Average Mortgage Broker Fee UK 2026: What You Should Expect to Pay

A mortgage broker (also called a mortgage adviser or intermediary) arranges mortgages on behalf of borrowers, typically accessing lenders that borrowers cannot approach directly or providing whole-of-market advice across multiple lenders. Brokers are paid in one or two ways: a fee charged directly to the borrower, a procuration fee paid by the lender on completion of the mortgage, or a combination of both.

What the FCA Requires Brokers to Disclose

All mortgage brokers regulated by the FCA must comply with the Mortgage Conduct of Business sourcebook (MCOB). Under MCOB 4.4A, brokers must provide a clear written disclosure of:

• Whether they charge a fee to the customer and the exact amount or how it will be calculated
• Whether they receive a procuration fee from the lender and the amount or basis of that fee
• Whether they are restricted (limited lender panel) or whole-of-market
• The nature of their service - advised or execution only

This disclosure must be provided before advice is given, in the Initial Disclosure Document (IDD) or combined Mortgage Illustration. Never proceed with a broker who does not provide written fee disclosure upfront.

Fee-Free vs Fee-Charging Brokers

Fee-free brokers are not free - they are paid by the lender via a procuration fee, typically 0.35% to 0.5% of the mortgage loan amount. On a £250,000 mortgage at 0.4%, the lender pays the broker £1,000. This cost is factored into the lender's pricing but is not visible to the borrower as a separate line item.

The key difference between fee-free and fee-charging brokers is not always cost - it is often panel access. Some fee-free brokers work from a restricted panel of lenders. Whole-of-market fee-charging brokers access the entire lending market including lenders that do not pay procuration fees or only distribute through fee-charging brokers.

For standard residential cases with straightforward income and good credit, a fee-free broker may provide exactly the service needed. For complex cases - self-employed, adverse credit, portfolio landlord, HMO, bridging - a whole-of-market specialist broker with a fee is often worth the additional cost.

When to Pay a Higher Fee

Higher broker fees of £750 to £2,000+ are typical for specialist cases including:

• Self-employed borrowers with complex income structures requiring specialist lender assessment
• Adverse credit or previous CCJs requiring specialist adverse lenders
• Portfolio landlords requiring whole-portfolio PRA underwriting coordination
• HMO mortgages requiring specialist lender panel access
• Bridging and commercial finance cases requiring specialist origination
• Expat and foreign national mortgages

In these cases, the broker's ability to access the right lender at the right rate typically saves far more than the fee cost over the mortgage term.

How to Check a Broker Is FCA Authorised

Before using any mortgage broker, check their FCA authorisation at register.fca.org.uk. Search by firm name or FCA reference number. Authorised firms are permitted to give regulated mortgage advice. Appointed representatives operate under the authorisation of a principal firm - check the principal firm's authorisation if the broker is listed as an appointed representative.

If you have a complaint about a mortgage broker, you can refer it to the Financial Ombudsman Service (FOS) at financial-ombudsman.org.uk after following the firm's own complaints procedure.

How much does a mortgage broker cost in the UK?

Mortgage broker fees for standard residential cases typically range from £0 (fee-free, paid by lender) to £499 for simple cases and £500 to £999 for more complex cases. Specialist cases including self-employed, adverse credit, or portfolio landlords can attract fees of £750 to £2,000 or more. The average fee for a standard residential mortgage is around £500 to £600.

Are fee-free mortgage brokers really free?

Fee-free means no charge to the borrower - the broker is paid a procuration fee by the lender, typically 0.35% to 0.5% of the mortgage amount. This cost is factored into lender pricing but is not charged to you directly. Fee-free brokers may have a restricted lender panel, which is worth checking for complex cases.

Is a mortgage broker fee worth paying?

For standard cases, a good fee-free whole-of-market broker provides the same quality of service as a fee-charging one. For complex cases - self-employed income, adverse credit, HMO, portfolio landlord - a specialist whole-of-market broker with a fee typically finds better rates and lenders than going direct, saving more than the fee cost over the mortgage term.

What must a mortgage broker disclose about their fees?

Under FCA MCOB rules, brokers must disclose in writing before giving advice: the exact fee or how it is calculated, whether they receive a procuration fee from the lender and how much, whether they are restricted or whole-of-market, and the nature of their service. This is provided in the Initial Disclosure Document.
