Introduction
Taking out a personal loan should be straightforward and transparent. Unfortunately, some UK borrowers experience problems ranging from unfair charges and poor customer service to unaffordable lending and misleading information during the application process.
If you believe a lender has treated you unfairly, you have legal rights. The UK’s financial regulatory framework gives consumers several ways to challenge lenders, seek compensation, and resolve disputes. Understanding how to complain about personal loan UK FCA Ombudsman guide procedures can help you achieve a fair outcome while avoiding unnecessary stress.
This guide explains your rights, how to submit an effective complaint, when to involve the Financial Ombudsman Service (FOS), and what support is available if you need assistance.
Your Rights as a UK Personal Loan Borrower
FCA Consumer Duty — What Lenders Must Provide
The Financial Conduct Authority (FCA) introduced the Consumer Duty framework to strengthen consumer protection standards. The rules came into force for most open products and services on 31 July 2023 and require firms to act to deliver good outcomes for retail customers. The Duty requires firms to act in good faith, avoid foreseeable harm, and support customers in achieving their financial objectives.
For personal loan customers, this means lenders should:
- Provide clear and understandable information
- Explain fees and charges transparently
- Assess affordability responsibly
- Avoid misleading sales practices
- Offer appropriate support when customers experience financial difficulties
- Handle complaints fairly and promptly
When lenders fail to meet these standards, borrowers may have grounds for a complaint.
Consumer Credit Act 1974 — Key Borrower Protections
The Consumer Credit Act 1974 remains one of the most important pieces of legislation protecting UK borrowers.
The Act provides protections relating to:
- Loan agreements
- Early settlement rights
- Credit advertising
- Default notices
- Consumer cancellation rights
- Unfair relationships between lenders and borrowers
If a lender has breached the requirements of the Act, this may strengthen your complaint.
What Counts as Unfair Treatment by a UK Lender
Examples of situations that may justify a complaint include:
- Loan approval despite obvious affordability issues
- Misleading information about costs or interest rates
- Incorrect charges or fees
- Administrative errors causing financial loss
- Failure to assist vulnerable customers
- Aggressive debt collection tactics
- Failure to investigate disputes properly
- Credit file errors caused by the lender
- Discrimination or unfair treatment
Not every disagreement results in compensation, but lenders must investigate complaints fairly and provide a reasoned response.
Step 1 — Complaining Directly to Your UK Lender
Before involving regulators or the Ombudsman, you must first give the lender the opportunity to resolve the issue.

What the Lender Must Do Within 8 Weeks
The FCA requires regulated firms to investigate complaints promptly.
In most cases, lenders must provide a final response within eight weeks of receiving a complaint. If they cannot resolve the issue within this period, they must explain the delay and inform you of your right to approach the Financial Ombudsman Service.
During the investigation, the lender may:

Getting a Final Response Letter
