Bitcoin and the UK Regulatory Landscape: What Is Changing and What Is Not

Bitcoin UK regulation is the editorial entry point for this explainer. The sources available for this piece — primary documents from the Financial Conduct Authority (FCA) and HM Treasury — speak to how the UK is bringing a broad set of cryptoasset activities and firms into a regulatory framework. They describe new regulated activities, financial‑promotion standards and transitional arrangements for firms, and they set dates for when particular parts of the regime will apply. The sources do not offer a single, universal legal classification of Bitcoin itself; instead they describe the treatment of cryptoasset activities, firms, promotions and market arrangements within UK law and policy.

Why this explainer exists

This piece collects, organises and explains the FCA’s and HM Treasury’s primary statements about the evolving UK regulatory approach to cryptoasset activities. It aims to help readers understand the regulatory framework as set out by those official sources — what has been decided, what is planned, and how different regulatory statuses relate to each other — without making legal, tax, investment or compliance determinations that the sources themselves do not make.

How to read this piece (scope and limits)

All regulatory facts in this article are attributed to the FCA or HM Treasury. Where the FCA or HM Treasury describe future steps, this article marks them as future rules or planned measures.
This article discusses regulatory treatment of cryptoasset activities, firms, financial promotions and market arrangements as described by the FCA and HM Treasury. It does not create or assert a universal legal classification for any particular cryptoasset, including Bitcoin.
The piece does not assess or state the regulatory status of any named firm, platform, wallet provider, advertisement, or individual holding cryptoassets.
Statements summarising or explaining regulatory distinctions are descriptive and based on the specified primary‑source material. They do not substitute for legal or compliance advice.

What the FCA and HM Treasury have published (summary)

Legislation and legislative context

HM Treasury says the government confirmed in November 2024 that it would proceed broadly in line with earlier proposals; it published draft statutory provisions in April 2025 and laid final legislation in Parliament on 15 December 2025. HM Treasury says the regime will create new regulated activities for cryptoassets, including operating a cryptoasset trading platform and issuing stablecoin, and will include admissions, disclosures and market‑abuse arrangements. (Source: HM Treasury)
The FCA states that the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 were passed by Parliament on 4 February 2026. The FCA says those Regulations brought a broad range of cryptoasset activities within the FCA’s regulatory perimeter for the first time, beyond the anti‑money‑laundering and financial‑promotion standards that previously defined the FCA’s role in the market. (Source: FCA)

FCA policy statements and activity‑specific material

The FCA says its policy statements set final rules and guidance for cryptoasset firms that will need FCA authorisation. The FCA describes activity‑specific material addressing firms that provide trading, dealing, custody, staking, and lending or borrowing services. The FCA also says separate material concerns admissions and disclosures and a market‑abuse regime for cryptoassets, including public offers and admission to trading on UK qualifying cryptoasset trading platforms. The FCA notes that cryptoasset markets are comparatively higher risk and that residual market‑abuse risk may remain higher than in more established markets. The FCA says the full scope of regulated activities under the regime will expand from 25 October 2027. (Source: FCA)

The current standing for firms operating now: MLR registration

The FCA states that a firm providing in‑scope cryptoasset services in the UK must register under the Money Laundering Regulations (MLRs) before it starts trading. Until the new Financial Services and Markets Act (FSMA) regime starts, firms must continue to meet the MLR registration requirement. The FCA says that firms providing in‑scope cryptoasset services must register under the MLRs before commencing trading. (Source: FCA)
The FCA emphasises that, under the new regime, firms carrying on regulated cryptoasset activities will need FSMA authorisation, including firms already registered under the MLRs. The FCA explicitly says that MLR registration does not guarantee later FSMA authorisation. (Source: FCA)

The planned FSMA cryptoasset regime: applications and commencement

The FCA explains that HM Treasury’s October 2023 proposals created new regulated activities for cryptoassets that will require firms wishing to provide associated services in or to the UK to be authorised and supervised by the FCA. The FCA says the Cryptoassets Regulations were made by Parliament on 4 February 2026. (Source: FCA)
The FCA says its final rules and guidance will apply to cryptoasset firms granted permission to operate under FSMA on or after 25 October 2027; the FCA says the new regime is expected to come into force on that date. The FCA says FSMA authorisation applications open on 30 September 2026 and that the regime is expected to start on 25 October 2027. These dates are presented by the FCA as part of its implementation timeline; the FCA describes the 30 September 2026 opening of applications and the expected 25 October 2027 start as part of the transition toward the FSMA regime. (Source: FCA)

Activities covered by the FCA’s final rules and guidance

The FCA says its activity‑specific material covers firms providing trading, dealing, custody, staking, and lending or borrowing services. The FCA also says there is separate material on admissions and disclosures and a market‑abuse regime for cryptoassets, including public offers and admission to trading on UK qualifying cryptoasset trading platforms. (Source: FCA)
The FCA describes cryptoasset markets as comparatively higher risk and notes residual market‑abuse risk may remain higher than in more established markets. (Source: FCA)

Financial promotions: what the FCA requires

The FCA says cryptoassets were classified as restricted mass‑market investments. The FCA says they may be mass marketed to UK consumers subject to restrictions and the overarching requirement that financial promotions are fair, clear and not misleading. (Source: FCA)
The FCA lists restrictions including clear risk warnings, a ban on incentives to invest, positive frictions, client categorisation and appropriateness assessments. The FCA says the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers regardless of where they are based or what technology is used. (Source: FCA)

Admissions to trading, disclosures and market‑abuse arrangements

The FCA states that its policy material includes provisions on admissions and disclosures and a market‑abuse regime for cryptoassets, including public offers and admission to trading on UK qualifying cryptoasset trading platforms. (Source: FCA)

Distinct regulatory statuses and what they mean

The FCA and HM Treasury materials set out different regulatory touchpoints. The descriptions below quote or paraphrase the sources; each paragraph indicates the source.

MLR registration (FCA): The FCA says a firm providing in‑scope cryptoasset services in the UK must register under the Money Laundering Regulations before it starts trading. Until the FSMA regime starts, firms must continue to meet that registration requirement. The FCA also says MLR registration does not guarantee FSMA authorisation. (Source: FCA)
FSMA authorisation (FCA): The FCA explains that new regulated activities for cryptoassets were created through the Regulations that Parliament passed on 4 February 2026. The FCA says its final rules and guidance will apply to firms granted permission under FSMA on or after 25 October 2027, and that applications for FSMA authorisation will open on 30 September 2026. The FCA says firms carrying on regulated cryptoasset activities under the new regime will need FSMA authorisation, including firms already registered under the MLRs. (Source: FCA)
Financial promotions (FCA): The FCA says cryptoassets were classified as restricted mass‑market investments and that the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers regardless of where they are based or what technology is used. The FCA lists the promotional restrictions and the overarching requirement that promotions be fair, clear and not misleading. (Source: FCA)
Asset ownership (context from FCA/HM Treasury): The FCA and HM Treasury materials focus on regulated activities, firms, promotions and market arrangements. Neither the FCA nor HM Treasury in the provided sources creates a single, universal legal classification for Bitcoin or any other specific cryptoasset across all contexts. This piece does not assert such a classification. (Sources: FCA, HM Treasury)

Myth‑versus‑distinction table (MLR registration, FSMA authorisation, financial promotions, Bitcoin asset ownership)

The table below explains common confusions using the FCA’s and HM Treasury’s statements. It does not make new legal determinations.

Myth	What the FCA/HM Treasury say	Practical distinction (explanation)
“MLR registration means a firm is authorised by the FCA for all crypto activity.”	The FCA says firms providing in‑scope cryptoasset services must register under the MLRs before trading, and that MLR registration does not guarantee FSMA authorisation.	MLR registration is an anti‑money‑laundering requirement. FSMA authorisation is a separate permission governed by the Cryptoassets Regulations and FCA rules; registration under the MLRs does not equal FSMA authorisation. (Source: FCA)
“If a firm is authorised under FSMA, financial promotion rules do not apply.”	The FCA says the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers regardless of where they are based.	Financial‑promotion requirements operate alongside other permissions; they apply to promotions directed at UK consumers and impose restrictions irrespective of an underlying FSMA status. (Source: FCA)
“A public announcement about Bitcoin automatically triggers admission rules.”	The FCA says it has separate material on admissions and disclosures and a market‑abuse regime for cryptoassets, including public offers and admission to trading on qualifying platforms.	Admissions and market‑abuse arrangements are specific to offers, disclosures and platforms as described by the FCA; not every public statement or announcement will fit those regulatory categories. (Source: FCA)
“This set of papers tells you the universal legal status of Bitcoin for every use.”	The FCA and HM Treasury materials focus on regulated activities, firms, promotions and market arrangements rather than a single, universal classification for any specific asset.	The regulatory materials set rules for activities and firms and describe future regimes; they do not assert a single status for an asset across all contexts. (Sources: FCA, HM Treasury)

Three clarifying tables

Table 1 — Status distinctions (MLR registration, FSMA authorisation, financial promotions, asset holding)

This table explains differences using the precise framing the FCA and HM Treasury supply.

Status or concept	How the FCA or HM Treasury describe it	What this explains
MLR registration	The FCA says a firm providing in‑scope cryptoasset services in the UK must register under the Money Laundering Regulations before it starts trading; this requirement continues until the new FSMA regime starts.	MLR registration concerns anti‑money‑laundering compliance and a firm’s permission to commence trading under the MLRs. (Source: FCA)
FSMA authorisation	The FCA says its final rules and guidance will apply to firms granted permission under FSMA on or after 25 October 2027; FSMA authorisation applications open on 30 September 2026. The Cryptoassets Regulations were made by Parliament on 4 February 2026.	FSMA authorisation is the permission regime under the new Cryptoassets Regulations; firms carrying on regulated cryptoasset activities will need FSMA authorisation when the regime applies. (Source: FCA)
Financial promotions	The FCA says cryptoassets were classified as restricted mass‑market investments and that the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers; restrictions include risk warnings, a ban on incentives, positive frictions, client categorisation and appropriateness assessments.	Financial‑promotion rules govern how cryptoassets may be marketed to UK consumers and apply in addition to firm permissions. (Source: FCA)
Individual asset holding	The FCA and HM Treasury materials in the provided sources speak primarily to activities, firms, promotions and market arrangements; they do not set a single universal legal classification for a particular cryptoasset in every context within these pages.	Discussions of regulated activities and permissions are distinct from private asset ownership; the sources do not equate one with the other. (Sources: FCA, HM Treasury)

Table 2 — FCA activity‑specific material (what the FCA says it covered)

The FCA describes final rules and guidance covering the following activity categories. This table summarises that description without expanding into additional conclusions.

Activity category	How the FCA described its coverage
Trading	The FCA says activity‑specific material covers firms providing trading services. (Source: FCA)
Dealing	The FCA says it covers dealing services in its activity‑specific material. (Source: FCA)
Custody	The FCA says custody is addressed in its activity‑specific material. (Source: FCA)
Staking	The FCA says staking is covered by its activity‑specific material. (Source: FCA)
Lending / borrowing	The FCA says lending or borrowing services are part of its activity‑specific material. (Source: FCA)
Admissions / disclosures	The FCA says it has separate material concerning admissions and disclosures. (Source: FCA)
Market‑abuse regime	The FCA says it has a market‑abuse regime for cryptoassets, including for public offers and admission to trading on UK qualifying cryptoasset trading platforms. (Source: FCA)

Table 3 — Dated timeline summary (key legislative and implementation dates cited by FCA / HM Treasury)

This table summarises the specific dates and the source that states them. Where a date relates to a future step in the source, the table labels it as a planned or future rule.

Date	Event	Source and note
November 2024	Government confirmed it would proceed broadly in line with earlier proposals.	HM Treasury describes this as policy context. (Source: HM Treasury)
April 2025	Draft statutory provisions published.	HM Treasury describes this as part of the legislative process. (Source: HM Treasury)
15 December 2025	Final legislation laid in Parliament (policy context per HM Treasury).	HM Treasury notes final legislation was laid on this date. (Source: HM Treasury)
4 February 2026	The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 were passed by Parliament.	The FCA says Parliament passed the Regulations on this date. (Source: FCA)
30 September 2026	FSMA authorisation applications open (future step described by the FCA).	The FCA states applications will open on this date. The FCA presents this as part of the transition toward the new regime. (Source: FCA)
25 October 2027	The FCA says the new FSMA cryptoasset regime is expected to come into force and that the full scope of regulated activities will expand from this date (future rules).	The FCA describes this as the expected commencement date for the new regime; the FCA presents this date as part of its implementation timeline. (Source: FCA)

What a reader should not infer

Do not infer from these sources that any specific cryptoasset, including Bitcoin, has one universal UK regulatory status across all contexts. The FCA and HM Treasury materials focus on activities, firms, promotions and market arrangements; they do not present a single, universal legal classification for particular assets in all uses. (Sources: FCA, HM Treasury)
Do not conclude that MLR registration equals FSMA authorisation. The FCA explicitly says MLR registration does not guarantee FSMA authorisation. (Source: FCA)
Do not assume that meeting financial‑promotion rules alone satisfies any separate authorisation requirement. The FCA says financial‑promotion requirements apply to how cryptoassets are marketed to UK consumers, and those rules operate in conjunction with permissions and registration requirements described elsewhere. (Source: FCA)
Do not treat the set of FCA policy statements and HM Treasury documents as legal advice. They set out rules, guidance and legislative context; any application of those rules to a particular business or situation requires specific legal or compliance assessment beyond this explainer.

Questions to ask before acting

Before making any decision that depends on the UK regulatory position for cryptoassets, these are practical questions worth checking with a qualified adviser or through official channels (this list is for orientation only and not advice):

Does the activity you or a firm intend to conduct fall into the activity‑specific categories the FCA describes (trading, dealing, custody, staking, lending/borrowing)? The FCA lists those categories in its activity‑specific material. (Source: FCA)
Is the activity in‑scope for MLR registration today? The FCA says firms providing in‑scope cryptoasset services in the UK must register under the MLRs before trading. (Source: FCA)
Will FSMA authorisation be required for the activity once the new regime applies? The FCA says firms carrying on regulated cryptoasset activities will need FSMA authorisation when the new regime applies; the FCA says applications open on 30 September 2026 and the regime is expected to start on 25 October 2027. (Source: FCA)
Are financial‑promotion rules relevant to any marketing or communications you plan to direct at UK consumers? The FCA says the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers regardless of where they are based; the FCA lists required risk warnings, a ban on incentives, positive frictions, client categorisation and appropriateness assessments. (Source: FCA)
If an activity involves public offers or admission to trading, how do the FCA’s admissions, disclosure and market‑abuse arrangements apply? The FCA has separate material on these topics as part of its final rules and guidance. (Source: FCA)

Illustration: the UK policy and regulatory context discussed in this source-linked explainer.

Reading the framework by activity

Start with a map of the official source categories the UK government and the Financial Conduct Authority (FCA) have published. The framework for cryptoassets is not a single document but a set of interlocking sources that speak to different activities, different timings and different obligations. Treat each publication as a layer of the map: primary legislation and Treasury policy notes, FCA policy statements and supervisory guidance, operational pages that explain how and when permissions will be handled, and targeted guidance on interim registration under the Money Laundering Regulations (MLRs).

HM Treasury’s policy note and draft/final instruments set out the shape of the regulated activities that Parliament approved. The Treasury states it laid final legislation in Parliament and that the regime creates new regulated activities, including operating a cryptoasset trading platform and issuing a stablecoin, and adds admissions/disclosures and market‑abuse arrangements (HM Treasury policy paper). The FCA’s policy statements then provide activity‑specific rules and narrative for trading, dealing, custody, staking and lending/borrowing, plus separate arrangements for admissions/disclosures and market abuse, as the FCA itself summarises (FCA cryptoasset regime overview).

Alongside those rule and policy documents the FCA maintains operational pages that explain the timing and process for firms seeking permission under the new Financial Services and Markets Act (FSMA) regime. The FCA’s “new regime” page describes when the authority expects the new FSMA permissions to apply and notes Treasury proposals requiring regulated activities and associated services provided in or to the UK to be authorised and supervised (FCA new‑regime page). Separately, and relevant to the interim period before the FSMA regime fully kicks in, the FCA’s guidance on registration under the MLRs sets out how firms should operate under the anti‑money‑laundering registration route and makes clear that registration under the MLRs is an interim measure that does not guarantee later FSMA authorisation (FCA MLR registration guidance).

The FCA’s policy statement on financial promotions (PS23/6) is a third, distinct source category. The FCA describes cryptoassets as restricted mass‑market investments and sets out rules for marketing to UK consumers: communications must be fair, clear and not misleading; risk warnings must be clear; there is a ban on investment incentives; firms should use positive frictions, client categorisation and appropriateness assessments; and the regime applies to all firms marketing cryptoassets to UK consumers regardless of location or technology used (FCA PS23/6).

Reading these documents together gives a reader a map by activity: what the Treasury has legislated as regulated activities; how the FCA intends to regulate specific activities once the FSMA regime applies; what firms must do in the interim under the MLRs; and the separate overlay of financial‑promotion obligations that apply to communications with consumers. Where a reader sees an activity in one document, they should check the others for timing, transitional arrangements and any additional policy detail.

Current obligations and future permissions

The materials make a basic temporal distinction that matters for any activity‑based reading. HM Treasury and the FCA identify transitional and destination states.

HM Treasury explains the new set of regulated activities created by legislation, including operating a cryptoasset trading platform and issuing a stablecoin, and that the regime also covers admissions, disclosures and market‑abuse arrangements (HM Treasury policy paper). The FCA’s overview notes that the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 were passed by Parliament and that the full scope of regulated activities expands from 25 October 2027; FCA policy statements address activity‑specific material for trading, dealing, custody, staking and lending or borrowing, plus separate admissions/disclosures and market‑abuse arrangements (FCA cryptoasset regime overview).

For the current, interim period the FCA has said firms providing in‑scope cryptoasset services in the UK must register under the MLRs before trading until the new FSMA regime begins. That registration is a money‑laundering registration requirement and is separate from FSMA authorisation; the FCA further states that MLR registration does not guarantee later FSMA authorisation (FCA MLR registration guidance). The FCA also notes operational dates for applications into the FSMA regime: FSMA authorisation applications open on 30 September 2026, while the FCA’s material explains final rules apply to cryptoasset firms granted permission under FSMA on or after 25 October 2027 (FCA new‑regime page).

At the same time, the FCA’s policy work characterises cryptoasset markets as comparatively higher risk and warns that residual market‑abuse risk may remain higher than in more established markets (FCA cryptoasset regime overview). That assessment helps explain why the FCA’s activity‑specific statements and the Treasury’s legislation take a granular approach to different activities (trading, custody, staking, lending/borrowing, admissions and market‑abuse arrangements).

It is important to read the publications as separate but connected permissions and obligations. MLR registration addresses anti‑money‑laundering reporting and registration obligations in the interim. FSMA authorisation under the new regime is the future permissions route for the defined regulated activities. Financial‑promotion rules (PS23/6) are a separate regulatory layer that governs how cryptoassets may be marketed to UK consumers at all times covered by the policy. None of those source categories — MLR registration, FSMA authorisation or financial‑promotion rules — should be treated as interchangeable or, by itself, as proof of another status.

Why promotion rules are a separate layer

Financial‑promotion rules operate across activities rather than replacing activity‑specific permissions. PS23/6 states that cryptoassets are restricted mass‑market investments and that firms marketing to UK consumers must comply with a package of requirements: fair, clear and not misleading communications; clear risk warnings; no investment incentives; positive frictions; client categorisation and appropriateness assessments (FCA PS23/6).

The FCA emphasises that these rules apply irrespective of where a firm is located or what technology it uses. That means the promotion rules sit alongside the substance of whether an activity is regulated under the FSMA regime or whether a firm is registered under the MLRs. Promotion rules do not, on their own, authorise a firm to carry on a regulated activity under FSMA; they regulate how products are marketed to certain categories of customers and the communications that reach consumers.

For readers following the evolving picture for Bitcoin UK regulation, treat promotion rules as an overlay. They restrict how cryptoassets can be described, advertised and incentivised to UK consumers and impose client‑suitability‑type processes where firms seek to communicate about restricted mass‑market investments. At the same time, the scope and timing of which activities become FSMA‑regulated — and which firms will need to be authorised to carry out those activities — are governed by Treasury legislation and the FCA’s FSMA implementation materials.

Repeat and keep in view: MLR registration, future FSMA authorisation and financial‑promotion rules are separate source categories and none alone proves another status. A registration under the MLRs is an interim anti‑money‑laundering arrangement; FSMA authorisation is the permissioning route for the defined regulated activities; and PS23/6 governs marketing and promotions to consumers.

Hypothetical (labelled): Worked reading exercise — questions raised by the official materials

Note: this is a hypothetical reading exercise. It poses questions that emerge from the FCA and Treasury publications; it does not answer them or recommend any course of action.

Hypothetical scenario: A reader is trying to understand how the official materials apply to a particular cryptoasset activity that involves custody, a secondary trading facility and customer communications directed at UK consumers.

Questions raised by the official materials:
– Which document defines whether custody or operating a secondary trading facility falls within the new regulated activities created by legislation? (See HM Treasury policy note and the statement that final legislation created a set of regulated activities, including trading platforms and stablecoin issuance: HM Treasury policy paper.)
– For activity‑specific requirements such as custody and trading, which FCA publication provides the detailed rules and narrative a reader should consult? (See the FCA’s policy statements describing trading, dealing, custody, staking and lending/borrowing: FCA cryptoasset regime overview.)
– If the activity is to be undertaken before the new FSMA regime is in force, what interim registration route is described and which FCA page sets out that requirement? (See the FCA MLR registration guidance on registration under the MLRs ahead of the new FSMA regime: MLR registration guidance.)
– What does the FCA say about the relationship between MLR registration and later FSMA authorisation? (See the explicit statement that MLR registration does not guarantee FSMA authorisation and that FSMA authorisation applications open on 30 September 2026: MLR registration guidance.)
– For communications to UK consumers about the activity, which source governs the form and content of promotions and what are the main promotional constraints? (See PS23/6 for the requirements on fair, clear and not misleading communications, clear risk warnings, a ban on investment incentives, positive frictions, client categorisation and appropriateness assessments, and the rule that the regime applies regardless of the promoter’s location: FCA PS23/6.)
– How do the FCA and Treasury describe market‑abuse risk and the regulatory interest in admissions and disclosure arrangements? (See the Treasury note on admissions and market‑abuse arrangements and the FCA’s statement that cryptoasset markets are comparatively higher risk with residual market‑abuse risk potentially higher than in established markets: HM Treasury policy paper; FCA cryptoasset regime overview.)

These questions show how a reading exercise proceeds by mapping activity to the correct source(s). The materials themselves indicate where to look for definitions, interim requirements, timing of FSMA permissions and promotional obligations — but the materials do not, in the documents cited, provide a single, definitive “one‑line” conclusion that collapses all issues into one statement.

For readers tracking Bitcoin UK regulation, use this map to allocate each question to the right source: Treasury for legislative scope, FCA policy statements for activity rules, the FCA new‑regime pages for timing and application processes, MLR guidance for interim AML registration, and PS23/6 for promotional rules. Remember: each source answers specific questions; read them together to form a coherent view, but do not treat one document (for example, MLR registration, FSMA authorisation or financial‑promotion compliance) as proving the legal or regulatory status set out in another.

What this does not tell a reader
The FCA and HM Treasury material in the specified sources provide authoritative statements about regulation and intended implementation, but they do not provide the following:

They do not provide tax guidance or determinations. (Not in sources provided.)

The FCA describes its final rules and guidance as applying to cryptoasset firms granted permission to operate under FSMA on or after 25 October 2027. The FCA presents this date as the expected commencement of the new regime and labels the related provisions as future rules. (Source: FCA)

Hypothetical example (clearly labelled hypothetical)

This example is hypothetical and intended to illustrate distinctions between regulatory statuses described by the FCA. It does not refer to any real firm or person.

Hypothetical
– Company X plans to offer a platform that enables UK customers to trade a range of cryptoassets and offers custodial services for customers’ assets.
– Under the FCA’s description, Company X would today need to consider whether its planned services are in‑scope for MLR registration; the FCA says firms providing in‑scope cryptoasset services in the UK must register under the MLRs before they start trading. (Source: FCA)
– Under the FCA’s explanation of the FSMA regime, if Company X will be carrying on activities that the Cryptoassets Regulations define as regulated activities, Company X would need FSMA authorisation when the new regime applies. The FCA says applications for FSMA authorisation open on 30 September 2026 and that the regime is expected to start on 25 October 2027; the FCA also says that firms already registered under the MLRs will still need FSMA authorisation under the new regime and that MLR registration does not guarantee FSMA authorisation. (Source: FCA)
– If Company X plans to market to UK consumers, the FCA says the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers regardless of where they are based, and that cryptoassets were classified as restricted mass‑market investments subject to specified restrictions including clear risk warnings, a ban on incentives to invest, positive frictions, client categorisation and appropriateness assessments.

FAQ (concise)

Q: Does the FCA say Bitcoin is regulated in the UK?
A: The FCA and HM Treasury materials in the provided sources focus on cryptoasset activities, firms, promotions and market arrangements. They describe what activities and services will fall within the regulatory perimeter and how the regime will operate, but they do not create a universal legal classification for any particular asset in every context. (Sources: FCA, HM Treasury)

Q: Is being registered under the MLRs the same as being authorised by the FCA under FSMA?
A: No. The FCA says firms providing in‑scope cryptoasset services must register under the MLRs before trading today, and that under the new FSMA regime firms carrying on regulated cryptoasset activities will need FSMA authorisation. The FCA explicitly states that MLR registration does not guarantee FSMA authorisation. (Source: FCA)

Q: When does the FCA say the FSMA cryptoasset regime will start?
A: The FCA says the new regime is expected to come into force on 25 October 2027. The FCA also says FSMA authorisation applications open on 30 September 2026. The FCA presents those dates as part of its implementation timeline. (Source: FCA)

Q: Do the financial‑promotion rules apply to overseas firms marketing cryptoassets to UK consumers?
A: The FCA says the financial‑promotion regime applies to all firms marketing cryptoassets to UK consumers regardless of where they are based or what technology is used. (Source: FCA)

Q: What activities has the FCA prepared rules and guidance for?
A: The FCA says its activity‑specific material covers firms providing trading, dealing, custody, staking, and lending or borrowing services; it also has separate material on admissions and disclosures and a market‑abuse regime for cryptoassets. (Source: FCA)

Conclusion and a clear no‑advice notice

What is changing: The FCA and HM Treasury sources show a clear policy trajectory. HM Treasury describes the legislative process leading to the Cryptoassets Regulations, and the FCA describes final rules, guidance and the categories of activity‑specific material it has prepared. The FCA says the Cryptoassets Regulations were passed by Parliament (4 February 2026) and that the full scope of regulated activities under the regime will expand from 25 October 2027. The FCA also says FSMA authorisation applications open on 30 September 2026 and that firms providing in‑scope services today must register under the MLRs before trading. (Sources: HM Treasury, FCA)

What is not changing (in the sources): The FCA emphasises that MLR registration remains an immediate requirement for firms providing in‑scope cryptoasset services and that MLR registration does not guarantee future FSMA authorisation. The FCA also sets out that financial‑promotion rules apply to marketing to UK consumers regardless of firm location. (Source: FCA)
