Complaints against a UK business broker — your options
UK business broking is unregulated. There's no dedicated ombudsman, no FCA authorisation requirement, no mandatory fee disclosure. That doesn't mean you have no options — it means the options are court-based and evidence-based. Six escalating routes, honest timelines.
By Chris at Sell LtdLast updated Six escalating routes
Send by email and recorded post to the broker's registered office. State the facts, the specific breach, and the remedy sought (fee refund, contract termination, correction of information). Keep it factual, not emotional.
The International Business Brokers Association (IBBA) and the Business Transfer Agency (BTA) both accept complaints against member brokers. They can compel disciplinary review but cannot mandate compensation. Useful pressure — many brokers settle rather than face review.
The FOS only accepts complaints where the broker is FCA-authorised (rare in general business broking — more common with corporate finance boutiques). Check your broker's FCA authorisation status before assuming FOS jurisdiction.
For fee disputes under £10,000, small claims (Money Claim Online, moneyclaim.gov.uk) is fast and cheap (£70–£410 issue fee). No lawyer required, though corporate lawyer review of your claim summary is worth £300–£500 of time.
For larger fee or damages claims. Legal representation strongly recommended. Costs are recoverable if you win, which usually creates settlement pressure — many brokers settle rather than face a full hearing on documented underperformance.
For misleading advertising (retainer disguised, fees not disclosed clearly, success rates misrepresented), Trading Standards and the ASA can act on egregious cases. Won't recover your money but can force practice changes.
The regulatory gap — worth knowing
UK business broking sits in a genuinely unregulated space. There is no FCA authorisation requirement, no fee cap, no mandatory fee disclosure, no dedicated ombudsman, and voluntary trade codes (IBBA, BTA) carry limited enforcement weight. Your legal remedies are contractual and civil — court-based, evidence-based, slow. This is one of the strongest arguments for sector reform. Until it happens, contract literacy at signing is worth more than complaint strategy after the fact.

Frequently asked questions
How do I complain about a UK business broker?
Six routes, escalating: (1) direct written complaint to the broker, (2) trade body complaint (IBBA or BTA if the broker is a member), (3) Financial Ombudsman if the broker is FCA-authorised (rare in business broking), (4) small claims court for disputes under £10,000, (5) County Court for larger disputes, (6) Trading Standards or ASA for misleading advertising.
Are UK business brokers regulated?
No. UK business broking is unregulated. There is no FCA authorisation requirement for general business broking, no fee cap, no mandatory fee disclosure. Some corporate finance boutiques hold FCA authorisation, but retail-facing broker services generally don't.
Can I get a refund of my broker retainer?
Very rarely, and only if you can evidence a material breach — no work delivered, no buyer introductions in the promised timeframe, breached confidentiality, misleading pre-contract statements. Even then, expect to negotiate or litigate. Most retainer clauses define the money as earned on signing.
What's the Ombudsman route?
The Financial Ombudsman Service accepts complaints only where the firm is FCA-authorised. Most retail-facing UK business brokers are not FCA-authorised, so FOS has no jurisdiction. Check the FCA register (register.fca.org.uk) before assuming this route is available.
Is small claims court realistic?
For fee disputes under £10,000, yes. Money Claim Online (moneyclaim.gov.uk) is the standard route. Issue fee £70–£410 depending on amount. No lawyer required. Hearings typically 6–9 months from issue. Brokers often settle before hearing to avoid the reputational cost.
Can I complain about misleading fees?
Yes — Trading Standards and the Advertising Standards Authority can act on materially misleading advertising. Retainer disguised as 'preparation fee' when the marketing said 'no upfront fee', undisclosed minimum success fees, or falsely advertised completion rates are all actionable. Reports won't recover your money but can force practice changes.
What evidence do I need?
Everything in writing: the contract, all emails, missed milestones, marketing screenshots making the disputed claim, timeline of your requests and their responses. Contemporaneous notes of phone calls (dated). Save it all before serving notice.
How long do I have to complain?
For trade body complaints, usually 6 months from the incident. For small claims / court, the Limitation Act gives 6 years on contract disputes. For Trading Standards, no fixed limit but sooner is better. FOS: 6 months from the broker's final response.
Will complaining hurt my sale?
The sale is already hurt — that's why you're complaining. Practically: complaint procedures at any stage rarely delay a sale that was going to complete. If the broker was underperforming enough to warrant a complaint, moving to a different route usually improves outcomes.
Is there an ombudsman just for brokers?
No. There is no dedicated UK business broker ombudsman. Trade bodies (IBBA, BTA) run voluntary codes with limited enforcement. This is one of the strongest arguments for regulatory reform of the sector — but it's the state of play today.
What's the deposit dispute for buyers?
For buyers who paid a deposit to a broker on a deal that collapsed: most buyer deposits are refundable per contract if the seller pulls out. If the broker refuses release, the same small claims route applies. Send written demand first, then Money Claim Online.
Can I make the complaint public?
Yes, provided you stick to fact and don't defame. Trustpilot, Google Reviews and specialist forums accept fact-based reviews. Get a corporate lawyer to review anything you write publicly if the broker is threatening defamation action — the safest defence is documented truth.
