UK business broker fees typically range from 5% to 15% of the sale price for small businesses, often with a minimum fee and sometimes an upfront retainer. The structure varies widely — and understanding it before you sign anything is essential.
Quick Answer
A UK business broker will typically charge a success fee of between 5% and 12% of the completed sale price, sometimes with a minimum fee of £5,000–£15,000 regardless of outcome. Some brokers also charge an upfront instruction fee or a monthly retainer. The total cost depends on deal size, broker type and what services are included.
In short:always read the full agreement before signing, understand what triggers the fee, and be clear on what happens if the business does not sell.

How business broker fees work
A business broker acts as an agent for the seller — finding buyers, managing enquiries, facilitating negotiations and, in many cases, supporting the deal through to completion. In return they charge a fee, usually as a percentage of the final sale price.
Unlike estate agents selling residential property, business brokers are not regulated in the UK. There is no mandatory qualification, no licencing requirement and no industry-wide code of conduct that all brokers must follow. This means the quality, professionalism and fee structures vary considerably.
Understanding how broker fees work — and what you are and are not getting — before signing any agreement is one of the most important things you can do as a seller.
Typical fee structures
Business broker fee structures in the UK fall into several common patterns. Most brokers use a combination of elements.
Success fee only
The broker receives a percentage of the sale price only if a transaction completes. No sale, no fee. This is the simplest structure and aligns incentives — the broker only gets paid when you do.
In practice, pure success-fee-only arrangements are more common for larger deals where the broker is confident the business will sell. For smaller businesses, brokers typically add an upfront or retainer element to cover their costs.
Upfront fee plus success fee
The seller pays an upfront instruction fee (typically £500–£5,000) when engaging the broker. This covers the broker's preparation work — writing the listing, producing a business summary, photography and so on. A success fee is also charged on completion.
This is one of the most common structures for SME brokers. The upfront fee is generally non-refundable even if the business does not sell.
Monthly retainer plus success fee
The seller pays a monthly retainer (typically £200–£800 per month) throughout the marketing period, plus a reduced success fee on completion. This is more common for larger, more complex transactions or where the marketing period is expected to be long.
Fixed fee
Some brokers, particularly online-focused operators, charge a fixed fee for listing and marketing — regardless of whether the business sells. This is similar to a marketplace listing but with more hands-on service. The risk is that the fee is paid regardless of outcome.
What the fee covers
What a broker's fee includes varies significantly between firms. At the higher end, a full-service broker will typically provide:
Business valuation guidance
Preparation of a detailed confidential information memorandum (CIM)
Listing on major business-for-sale platforms
Marketing to their existing buyer database
Buyer enquiry handling and screening
NDA management
Facilitating meetings between buyer and seller
Negotiation support
Supporting due diligence management
Liaison with solicitors through to completion
At the lower end, a broker may simply list the business on their website and pass enquiries through to you to handle yourself.
Before signing, establish exactly what is included and what you will be expected to do yourself.
Upfront fees and retainers
Upfront fees are a normal part of many broker arrangements — but they deserve scrutiny.
What to check:
Is the upfront fee refundable in any circumstances?
What do you receive in return — a written valuation? A professional CIM? Photography?
Is the upfront fee credited against the success fee at completion?
How does the contract work if you decide to withdraw or the business does not sell?
A modest upfront fee (£500–£2,000) for a full written business summary and listing is generally reasonable. A large upfront fee (£3,000–£10,000+) without a very clear deliverable list is worth questioning.
Be cautious of any broker who requires a large upfront payment before you have seen the quality of their previous work or had a chance to check references. High-pressure tactics to sign quickly and pay immediately are warning signs.
Success fees and minimum fees
Success fee percentages
For businesses selling at under £250,000, success fees typically range from 8% to 15%. For businesses selling between £250,000 and £1 million, 5% to 10% is more common. For larger deals above £1 million, fees often fall to 2% to 5%.
These are general market ranges — individual brokers vary, and negotiation is possible, particularly if the business is likely to sell quickly or if there is a competitive situation between brokers.
Minimum fees
Most brokers apply a minimum fee regardless of the actual sale price. Common minimums are £5,000 to £15,000. This means that even if the business sells at a lower price than expected, the broker is guaranteed a floor payment.
A minimum fee of £5,000–£8,000 for a business selling at £50,000–£80,000 represents a very high effective percentage. Check the minimum fee and make sure it is reasonable relative to your expected sale price.
VAT
Broker fees are usually subject to VAT at 20%. Check whether the quoted fee is inclusive or exclusive of VAT — a 10% success fee plus VAT is effectively 12%.
Tiered and sliding scale fees
Some brokers use tiered success fees — a higher percentage on the first tranche of the sale price and a lower percentage above a threshold. For example:
10% on the first £100,000
7% on the next £150,000
5% above £250,000
This can work in the seller's favour if the business achieves a higher price, but it can also mean the effective total fee is harder to calculate upfront. Always ask for an example calculation at your expected sale price and at a higher and lower price.
What triggers the fee
The fee trigger is one of the most important clauses in any broker agreement. A fee becomes payable when a defined event occurs — but the definition of that event is critical.
Completion-based trigger:The fee is only payable when the sale legally completes and funds are received. This is the most seller-friendly trigger — if the deal falls apart, no fee is owed.
Exchange-based trigger:The fee triggers when contracts are exchanged, not when completion occurs. In most SME deals exchange and completion happen simultaneously, but if they are separate, this could mean paying a fee on a deal that later collapses.
Introduction-based trigger:The fee is payable if the sale completes with a buyer the broker introduced — even if the broker played no further role in the deal. This can cause problems if you later sell privately to a buyer the broker introduced years earlier.
Tail period:Many broker agreements include a "tail" — a period of 12 to 24 months after the agreement ends during which the fee is still payable if the business is sold to anyone the broker introduced. This is standard and reasonable, but check the length and definition of "introduction."
Broker vs marketplace: what is the difference?
It is worth understanding clearly what a broker does versus what a listing marketplace does, because they are not the same thing.
What they do - Act as your agent — valuate, market, negotiate, manage the deal - Provide a platform where you list your business for sale
Fee structure - Success fee (% of sale) + often upfront fee - Listing fee or subscription (fixed cost, not tied to sale)
Who manages buyers - The broker - You, the seller
Who writes the listing - Usually the broker - Usually you, or with guidance
Negotiation support - Yes — broker negotiates on your behalf - No — between buyer and seller directly
Due diligence support - Varies — better brokers help manage it - No
Legal involvement - Broker liaises with solicitors - No — you instruct your own solicitor
Regulation - Unregulated - Unregulated
A marketplace is not a broker, and a broker is not just a listing service. Both have a role depending on what you need.
If your business is straightforward, well-documented and you are comfortable dealing with buyers yourself, a marketplace listing gives you direct access to buyers at much lower cost.
If you want an agent to handle everything — valuating, writing, marketing, screening, negotiating, managing due diligence — a broker may be worth the fee, provided you choose one carefully.

How to choose a broker
If you decide to use a broker, the quality of the one you choose matters enormously. Here is what to assess.
Track record and specialisation
Ask how many businesses they have sold in your sector and at your price range in the last 12 months. A broker who specialises in hospitality is not the same as one who specialises in professional services. Ask for examples of completed deals — they will not share names but should be able to describe comparable transactions.
Buyer database
Ask how many active buyers are currently registered and looking for businesses in your sector and price range. A broker with a large, active database of pre-qualified buyers can market your business more quickly than one relying solely on listing platforms.
Realistic valuation
Be wary of brokers who give you an unusually high valuation during the pitch. Some brokers inflate their initial valuation to win the instruction, then gradually manage expectations downward after you are signed up. A good broker will give you a realistic range and explain the reasoning — not just tell you what you want to hear.
References
Ask for two or three references from sellers who completed a sale through the broker in the last two years. A reputable broker will be happy to provide these.
Contract terms
Read the full agreement before signing. Understand the fee, the trigger, the notice period, the minimum fee, the tail period and what happens if you want to terminate. If anything is unclear, ask for clarification in writing.
Questions to ask before signing
Before engaging any broker, get clear answers to these questions:
What is your success fee percentage and minimum fee?
Is there an upfront fee? If so, what does it cover and is it credited against the success fee?
What exactly triggers the fee — completion, exchange, or introduction?
What is the tail period after termination?
How long is the initial contract term and what is the notice period?
What is included in your service — valuation, CIM, photography, buyer screening, negotiation?
How many businesses have you sold in my sector and price range in the last 12 months?
How will you market the business and where will it be listed?
Can you provide two or three references from recent completed sales?
What happens if I find my own buyer — do I still owe you a fee?
Red flags to watch for
High upfront fees with vague deliverables
A demand for a large upfront fee (£3,000+) with no clear written specification of what you receive is a warning sign. Reputable brokers will specify exactly what your money covers.
High-pressure sales tactics
A broker who pressures you to sign immediately, tells you the market is about to change, or creates artificial urgency is not acting in your best interest. Take your time, compare options and read the agreement carefully.
Unrealistic valuations
A broker who quotes a sale price significantly above what others have suggested, without a clear evidenced rationale, may be trying to win your instruction rather than give you an accurate view. Overpriced businesses take longer to sell — or never sell — and waste months of your time.
Lack of transparency on fees
Any broker who is evasive about the total fee, who uses complex language to obscure what triggers payment, or who changes the terms once you are in the process is a concern.
No references or track record
A broker who cannot provide any evidence of completed sales in your sector should be treated with caution.
Excessive tie-in periods
A 12-month exclusive agreement with a six-month notice period means you could be locked in for 18 months even if the broker is delivering no results. Look for reasonable exclusivity terms — typically three to six months — with clear performance expectations.
FAQs
Do I have to use a broker to sell my business?
No. Many sellers list directly on a marketplace, handle their own buyer enquiries, and use a solicitor and accountant for the legal and financial aspects of the deal. A broker adds value when the business is complex, when you need access to an active buyer database, or when you do not have the time or experience to manage the sale process yourself.
Can I negotiate broker fees?
Yes. Broker fees are not fixed, and most will negotiate, particularly for larger deals, if the business is well-documented and likely to sell quickly, or if you are considering multiple brokers. Negotiation is normal and expected.
What if I find my own buyer?
This depends on your broker agreement. Many agreements include a clause stating that even if you find a buyer yourself during the contract period, the success fee is still payable. Read the contract carefully — and if you have an existing buyer in mind, discuss this upfront before signing.
Is a business broker regulated in the UK?
No. Business brokers are not regulated. There is no mandatory qualification or licencing requirement. Some brokers are members of professional bodies (such as the IBBA — International Business Brokers Association), but membership is voluntary. This means due diligence on your broker is your responsibility.
Should I use a local broker or a national one?
Both have advantages. A local broker may have strong regional buyer relationships and sector knowledge. A national broker has a larger database and wider marketing reach. The quality of the individual broker matters more than geography.
What is a Confidential Information Memorandum?
A CIM (also called an Information Memorandum or IM) is a detailed written document about your business prepared for serious buyers after NDA. It typically includes financial performance, business overview, assets, staff, lease, customers and reason for sale. A good broker will prepare this for you as part of their service.
Should I get professional advice before signing a broker agreement?
Yes. A broker agreement is a legally binding contract. If you are unsure about any term — particularly the fee trigger, tail period or exclusivity clause — ask a solicitor to review it before you sign.
Key takeaways
UK business broker fees typically range from 5% to 15% of the sale price, with minimum fees of £5,000–£15,000 and often an upfront element.
Always understand what triggers the fee — completion, exchange or introduction — before signing.
Tail periods mean the fee can be owed months after the agreement ends if you sell to a buyer the broker introduced.
High upfront fees, unrealistic valuations and high-pressure tactics are red flags — take your time and compare options.
A broker and a marketplace are not the same thing: a broker acts as your agent; a marketplace provides a platform for direct seller-buyer contact.
Broker fees are negotiable — particularly for larger or well-documented businesses.
Business brokers are unregulated in the UK — checking references and track record is your responsibility.
For straightforward businesses, a marketplace listing plus your own professional advisers may be a cost-effective alternative to a full broker service.
