Business transfer agent fees in the UK
UK business transfer agents (business brokers) typically charge either a retainer plus a lower success fee, or no upfront fee at all in exchange for a higher success fee when the sale completes — commonly landing between about 3% and 12% of the sale price on smaller deals, and well under 1% on the largest ones. Most agreements also include a sole-agency tie-in period, and some carry a withdrawal fee if you leave early. Because business transfer agents fall outside the law that regulates residential estate agents, the written contract — not a regulator — is what protects you.

How business transfer agents charge
A business transfer agent — usually just called a business broker — is the business-sale equivalent of an estate agent. It values the business, prepares marketing materials, finds buyers, and helps negotiate the deal. Nothing in UK law fixes how it can charge, so terms vary firm to firm, but they fall into two broad models.
The first is a retainer, or instruction fee, paid when you sign up, plus a lower success fee when the sale completes. Retainers for a straightforward small-business sale often run from a few hundred pounds up to around £5,000; for larger or more complex mandates handled by a corporate finance adviser, upfront fees can reach the tens of thousands of pounds. The success fee that follows is usually lower than in a no-retainer deal, commonly 3% to 5% of the sale price.
The second model is no-sale-no-fee: no retainer, nothing owed if the business doesn't sell, and a higher success fee — commonly 8% to 12% — if it does. Marketing costs, such as portal listings, a sales memorandum or photography, are sometimes bundled into the success fee and sometimes charged separately as a monthly fee regardless of outcome. Ask which applies before you sign.
What agents typically charge, by deal size
Success fees are usually quoted as a percentage of the final sale price, and the percentage tends to fall as the deal gets bigger, because the work involved doesn't scale up in proportion to the price. Typical ranges reported by UK business brokers and corporate finance advisers:
| Deal size | Typical success fee | What tends to apply |
|---|---|---|
| Smaller business (roughly up to a couple of million pounds) | 3%–10% of sale price, sometimes up to 12–15% on a no-retainer deal | Flat percentage, or a fixed minimum fee if that's higher — e.g. "£5,000 or 10% of the price, whichever is greater" |
| Mid-market (roughly £10m–£20m) | 2%–3.5% | Usually paired with a larger retainer |
| Larger deals (£20m+) | 0.5%–1% | Often a sliding scale (a “Lehman” or “double Lehman” formula) paying a higher rate on the first slice of the price and progressively less above it |
Add VAT to any quoted rate unless the agent confirms it's already included. And check what the percentage is calculated on: the headline sale price, or the total consideration including any deferred payment or earn-out — these can differ significantly.
Retainers, minimum fees and marketing costs
A retainer is meant to cover the agent's upfront work — valuing the business, preparing an information memorandum, and building a buyer list — win or lose. Ask exactly what it buys: a written valuation, professional photography, portal listings, or simply admin time.
Minimum fees matter more than the headline percentage on smaller deals. A broker quoting "10% of the sale price" with a £5,000 minimum charges the same 10% on a £500,000 sale but effectively far more than 10% on a £30,000 one. Ask for the minimum fee in pounds, not just as a percentage.
The exclusivity and withdrawal-fee trap
Most business transfer agreements include a period of sole agency (only this agent may market the business) or the stricter sole selling rights (you owe the fee even if you find the buyer yourself), running for a fixed term — commonly a matter of months — before you can appoint someone else or take the business off the market without penalty.
Watch for two specific clauses. A "ready, willing and able purchaser" clause — standard agency-contract wording that also turns up in some business-transfer agreements — means the agent earns the fee the moment it introduces a buyer able to complete at the asking price, even if you then decide not to sell. And a withdrawal fee (sometimes called a cancellation or abortive fee) charges you for taking the business off the market or switching agents during the tie-in period, on top of any retainer already paid. Sellers should be wary of any agreement combining an upfront fee with an open-ended withdrawal charge, and should ask for the exact figure in writing rather than accepting wording like "reasonable costs incurred." It's worth having a solicitor read the agency agreement itself, not just the eventual sale contract.
Why there's no regulator to complain to
Estate agents selling residential or commercial property are regulated under the Estate Agents Act 1979 and, if things go wrong, must belong to a redress scheme. But the Act only covers work done to buy or sell "an interest in land" — freehold or leasehold property. Selling a business's trading assets, stock and goodwill is not an interest in land, so a business transfer agent handling that kind of sale sits outside the Act: no licence requirement, and no compulsory redress scheme. If a sale also includes the freehold or leasehold premises the business occupies, that part of the transaction can bring the agent's property-related work back within the Act's scope.
In practice, that means the written contract is doing the job a regulator would otherwise do. UK government business-support guidance recommends checking that a transfer agent belongs to a recognised trade body — such as Propertymark or a business brokers' association — since membership carries a code of conduct even without statutory backing, and gives you somewhere to complain.
Not every seller pays an agent commission at all. Some list the business themselves first — bizflip, for example, lists businesses for sale at no cost — and only bring in a broker later if they want more reach or negotiating support.
Questions to ask before you sign
- Is this a retainer-plus-success-fee deal or no-sale-no-fee, and what's the percentage in each case?
- What is the minimum fee in pounds, not just as a percentage?
- Is the fee calculated on the full sale price, or does it exclude any earn-out or deferred consideration?
- Are quoted rates inclusive or exclusive of VAT?
- Is this sole agency, sole selling rights, or a non-exclusive (open) listing — and what does each mean for what I owe?
- How long is the tie-in period, and what notice do I need to give to end it?
- Is there a withdrawal or cancellation fee, and is the amount fixed or open-ended?
- Does a "ready, willing and able purchaser" clause, or anything similar, appear in the contract?
- What exactly does the retainer or marketing fee cover?
- What trade body, if any, does the agent belong to, and what's their complaints process?

- Estate agents (the regulatory model the Estate Agents Act 1979 covers) are not currently required by law to be licensed or qualified; the Act, plus the redress-scheme duty under the Consumers, Estate Agents and Redress Act 2007, is the principal statutory framework for this kind of agency work. — House of Commons Library
