How to fire a UK business broker
Six steps, a template letter, and the mistakes that cost sellers thousands. Notice periods run 30–90 days, retainers rarely refund, and tail fees can survive termination for a year or more — handled properly, you can walk away with minimal damage.
By Chris at Sell LtdLast updated The six-step termination
Standard UK broker contracts require 30 days' written notice, sometimes 90. Some are non-terminable for the first 6 months without cause. Establish exactly what your contract says before drafting anything.
If you have grounds for termination for cause — no buyer introductions in 90 days, missed marketing commitments, breached confidentiality — get the evidence in writing before you serve notice. Emails, missed milestones, undelivered work.
Registered office address, not personal email. Send by both email and recorded post. Reference the clause number you're relying on and the effective termination date.
The tail clause typically survives termination. Request in writing the broker's complete list of buyers introduced during the mandate. This is your named exclusion list for the tail period — anyone not on it is fair game.
The retainer is usually non-refundable and any earned commissions on live buyers may survive. Get a final statement in writing before terminating. Disputing later is much harder.
If the tail is 6–12 months and you can wait, do. If not, some brokers accept a small settlement to release the tail early. Get it in writing.

Termination of Mandate Agreement dated [date]
Dear [Broker contact],
I hereby give written notice to terminate the Mandate Agreement between
us dated [date], pursuant to Clause [X.X] (Termination).
The effective date of termination shall be [30/90 days from date of this
letter], being the notice period specified in the Agreement.
Prior to the effective date, I require:
1. A complete written list of all buyers introduced to the Business
during the Mandate ("Introduction List"), consistent with the
surviving obligations at Clause [X.X] (Tail).
2. A final statement of any outstanding fees, itemised.
3. Confirmation of any earned commissions in respect of live buyer
discussions, together with the basis on which they were earned.
The Introduction List, once confirmed in writing, shall be the
exclusive scope of the tail provisions. No other buyer shall be
subject to the Success Fee.
I remain willing to discuss a mutually satisfactory closure.
Yours sincerely,
[Signature]
[Your name]Template only — have a corporate solicitor review before sending on any mandate above £10,000 exposure.

Frequently asked questions
How do I fire my UK business broker?
Serve written notice in accordance with the termination clause of your contract (typically 30–90 days). Send to the broker's registered office by email and recorded post. Reference the clause you're relying on and the effective termination date. Get the introduction list in writing before termination takes effect.
Can I fire a broker mid-mandate?
Depends on your contract. Most UK broker mandates allow termination on 30 or 90 days' notice, some are non-terminable for an initial 6-month period without cause. Termination for cause (breach, non-performance, confidentiality breach) usually accelerates timings — but you need documented evidence.
Will I owe fees if I fire my broker?
The retainer is almost always non-refundable. If the broker introduced a buyer who later completes within the tail period, the success fee is owed. Any other outstanding invoices (marketing costs, disbursements) survive termination. Get a full final statement before serving notice.
What is a 'tail clause' and does it survive termination?
Yes, tail clauses survive termination. They typically entitle the broker to their success fee for 12–24 months post-termination if you sell to a buyer they introduced. Best defence: request the introduction list in writing at termination and only accept a written, dated list — not 'buyers we spoke about'.
Can I fire my broker without cause?
In most cases yes, if you comply with the notice period. You'll typically lose the retainer and remain subject to the tail. If you have documented cause, you may exit faster and dispute residual fees more successfully.
What counts as broker cause?
No buyer introductions in 90–180 days, missed milestones (IM not delivered, listing not published, promised marketing not run), breached confidentiality (revealed identity without consent), or unresponsiveness. Document everything in writing while it's happening.
Is there a template letter?
The template letter section below covers standard drafting — registered office, effective date, clause reference, introduction list request, final fee statement. Have a corporate lawyer review before sending on any mandate above £5,000 in fees or exposure.
What if my broker refuses to release the introduction list?
Send a follow-up written request citing your legal entitlement under contract and, if relevant, GDPR data-portability principles. If they still refuse, a solicitor's letter usually resolves it — brokers rarely want a dispute on documented non-cooperation.
Can I then list on Sell Ltd?
Yes — once your termination is effective and the exclusivity clause has ended. You remain bound only by the tail (which restricts specific buyers on the introduction list, not the platform itself). Sell Ltd's onboarding survey lets you name excluded buyers to ring-fence.
Will firing my broker damage the sale?
In our experience, no. Broker mandates that reach termination were usually not going to complete anyway — the underperformance signal is real. Sellers who fired an underperforming broker and moved to Sell Ltd often close within 3–4 months on the new mandate.
Do I need a lawyer?
For any mandate above £10,000 exposure, yes — one hour of a corporate solicitor's time (£300–£500) before serving notice will typically save far more than it costs. For smaller mandates, careful reading of the contract plus a well-drafted notice letter usually suffices.
How long does the process take?
From decision to full release: 30–90 days for the notice period, plus 6–24 months for the tail (only affecting named buyers). You can list elsewhere the day after the notice period ends, subject to the named-buyer tail restriction.
After termination — list on Sell Ltd
You can name excluded buyers in the survey so the tail is fully respected.
