Several important laws govern financial firms in the UK, but the Financial Services and Markets Act 2000 sits at the centre of the system. Other key legislation includes the Financial Services Act 2012, the Financial Services and Markets Act 2023, the Banking Act 2009, and regulations covering credit, payments and financial crime.
That may sound like a lot to take in, especially when different laws apply to different firms and activities. Learnera’s The Introduction to UK Financial Regulations & Professional Integrity provides structured CPD learning for anyone who wants a clearer understanding of UK regulation, ethical conduct and the responsibilities financial professionals may face.
Key Points
- FSMA 2000 forms the foundation of UK financial regulation.
- Other laws apply according to a firm’s activities, products and customers.
- The FCA and PRA provide detailed rules and supervision.
What is the main UK financial services law?
FSMA 2000 creates the broad framework for financial services regulation. It gives regulators powers, supports the authorisation system and underpins controls on regulated activities and financial promotions.
The Financial Services and Markets Act 2000 (Regulated Activities) Order 2001 helps define activities such as accepting deposits, managing investments and arranging certain deals. Under FSMA’s “general prohibition”, a person must not carry on a regulated activity in the UK by way of business unless authorised, exempt or covered by an exclusion.
Which other laws are important?
Different Firms, Different Rules
The legislation that applies depends on what a financial firm does, which products it provides and which customers it serves.
Each law addresses a different area, from banking stability and payments to consumer protection and financial crime prevention.
Financial Services Act 2012
Created the current FCA and PRA regulatory structure.
Financial Services and Markets Act 2023
Supports UK financial rules after retained EU law changes and extends regulatory powers.
Banking Act 2009
Provides tools for handling failing banks and protecting financial stability.
Banking Reform Act 2013
Introduced ring-fencing and stronger senior-management accountability.
Consumer Credit Act 1974
Important for consumer credit activities alongside FCA rules.
Payment & E-Money Rules
Cover payment services and electronic money businesses.
Money Laundering Regulations 2017
Set requirements to prevent money laundering and terrorist financing.
Financial Services Act 2012
This Act created the present FCA and PRA structure, shaping how financial firms are supervised in the UK.
There is no single law covering everything. The right rules depend on the firm's activities, products and responsibilities.
Is the FCA a law or a regulator?
The FCA is a regulator, not legislation. It regulates UK financial services firms, sets standards and holds firms to account. The PRA, part of the Bank of England, focuses mainly on the safety and soundness of banks, insurers and certain investment firms.
A simple way to remember the system is:
- Parliament creates legislation.
- Regulators supervise firms.
- The FCA Handbook and PRA Rulebook provide detailed requirements.
How does legislation affect everyday work?
The effect depends on the role. A compliance officer may review promotions and reporting controls. A customer-facing adviser may follow conduct and consumer-protection rules. Banking staff may work within prudential, operational-resilience and risk-management requirements.
Firms therefore combine legal advice, internal policies, workplace training and role-specific supervision. Reading one Act alone is rarely enough.
Do All Financial Firms Need FCA Authorisation?
Not automatically. It depends on the firm's activities, products, customers and whether an exemption or exclusion applies.
The short answer: No
Authorisation depends on what a firm does, not simply because it operates in financial services.
Activity
What regulated activity does the firm perform?
Products
What financial products or services are involved?
Permission
Correct FCA or PRA permission may be required.
Training
A certificate does not create authorisation.
Check the activity first
Firms should consider the activity they carry out, how it is performed and whether any exemption or exclusion applies before deciding if permission is needed.
Completing a financial regulation course improves knowledge but does not make an individual or business FCA authorised.
What should you remember?
UK financial regulation is a layered system, not one single law. FSMA 2000 provides the foundation, while later legislation, sector rules and regulator handbooks add detail. Understanding that structure helps professionals ask better compliance questions in their own roles.
