Mortgage Broker Costs 2026: How Much Do Mortgage Brokers Charge?

It would be easy to assume that paying a higher broker fee would mean you get unique access to better mortgage deals, lower interest rates or an improved service, but that isn’t always the case.

In this article, we break down exactly how much a mortgage broker costs, how broker fees work, what they cover, who pays them and whether they’re worth paying. Along the way, we draw on findings from the Boon Brokers 2026 Mortgage Broker Fees Study to help put common broker fees into context. Let’s begin.

How Much Do Mortgage Brokers Cost in the UK?

How much you are charged will largely depend on their specific business model. Some brokers will charge a fixed sum, others calculate their costs as a percentage of the loan amount, while many offer fee-free advice and receive commission from the lender instead.

This variation is reflected in the Boon Brokers 2026 Study, which found that the average fee paid by UK homebuyers was £643 for a purchase mortgage and £623 for a remortgage.

These figures represent market averages, meaning your actual cost will depend on the firm you choose. It’s also worth remembering that not every mortgage adviser will charge an upfront fee. Many fee-free mortgage broker services receive commission from the lender instead, allowing borrowers to receive regulated mortgage advice without paying for it.

While cost should always be an important consideration, it should not be the only factor when comparing brokers. Understanding what’s included in the fee, the level of advice and support provided, and how the broker is paid will usually give you a better indication of value than price alone.

How Do Broker Fee Structures Work?

It’s crucial to take note of how a broker’s payment model works. This can make it much easier to compare, assess the overall value and to choose the service that best suits your circumstances.

Fee-Free Mortgage Advice

A fee-free mortgage broker does not charge the borrower directly. This includes the mortgage advice and support provided throughout the application process. Instead, they receive commission from the mortgage lender once the mortgage completes.

This business model allows you to access regulated guidance without paying an advice fee yourself. With that said, it’s still important to confirm whether the firm offers whole-of-market advice as this can affect the range of lenders and products that can be recommended.

Fixed Charges

A fixed broker fee is a single agreed amount that remains the same regardless of the size of your mortgage application. This business model allows you to know exactly what the cost of advice and supporting services are from the start.

Fixed fees are one of the most common charging structures in the UK and are often used for standard residential mortgage applications.

Percentage-Based Fees

Some brokers will calculate their fee as a percentage of the mortgage amount being borrowed. This means your overall cost can increase as the size of the mortgage increases.

Although percentage-based fees are far less common than flat rates, percentage models are still used for higher-value borrowing or specialist lending cases.

Combination of Fees

A combination mortgage broker fee is where the total charge is made up from more than one type of borrower fee during the mortgage process. For example, they may charge a fixed fee when your application begins, followed by a percentage-based cost once your mortgage completes.

This business model is far less common and is only typically used for more complex mortgage applications. Before agreeing to proceed, make sure you understand exactly how each cost is calculated, when it becomes payable and what services are included.

Who Pays Mortgage Broker Fees?

All mortgage lenders will pay a mortgage broker commission. This is more commonly known as a procuration fee and is paid only when a mortgage completes.

Commission usually forms part of the lender’s normal distribution costs and compensates the broker for advising the borrower, recommending a suitable mortgage product and supporting the application through to completion.

While some fee-free brokers rely solely on this commission, other brokers will also charge the borrower a separate fee depending on their business model and the complexity of the case.

The answer to “Who pays?” will ultimately come down to the firm’s business model. The table below provides an overview under each business structure:

Under Financial Conduct Authority (FCA) rules, brokers are required to disclose their exact payment structure before providing advice.

What Do Broker Fees Cover?

As a general rule, the core services provided by a mortgage broker, such as giving regulated mortgage advice, recommending a suitable mortgage, managing the application and liaising with lenders, should all be broadly similar whether the broker charges a fee or offers free advice.

The only place where brokers often differ is in the level of support they can provide, the complexity of cases they specialise in, their experience and the overall customer service they offer.

For this reason, before paying a mortgage broker fee, it is always best practice to make sure the services being offered match your needs. This includes confirming the broker can support your type of application, has access to lenders suited to your circumstances and provides the level of guidance you expect throughout the mortgage process.

To help you understand what a mortgage broker fee typically covers, we’ve provided an overview of the services that are commonly included.

One of the most common misconceptions is that fee-free advisers provide a limited service simply because they don’t charge clients directly.

Our 2026 study revealed that 31% of borrowers who paid an upfront fee were actually unaware that fee-free mortgage brokers can often access the same lenders and products. In reality, fee-free advisers can provide the exact same regulated support, lender communication, and application management.

Ultimately, the most important consideration is whether the broker has access to lenders that suit your unique circumstances and can provide the level of guidance you need throughout the mortgage process.

Do All Mortgage Brokers Charge a Fee?

There is no standard pricing model for mortgage brokers in the UK. As we’ve explored, while some brokers choose to charge borrowers directly, others operate entirely on lender commission, allowing them to provide fee-free mortgage advice.

Why Do Some Mortgage Brokers Charge a Fee?

In the UK, brokers will ordinarily receive a procuration fee from the mortgage lender once a mortgage completes. Where a broker also charges the borrower a fee directly, this is typically in addition to the lender commission rather than instead of it.

Charging a fee is simply one business model and does not necessarily indicate that the broker has access to better mortgage products or provides a higher standard of regulated advice.

Some mortgage brokers choose to charge borrowers in addition to receiving commission, with the fee forming part of the firm’s overall charging structure.

Why Do Some Mortgage Brokers Offer Fee-Free Mortgage Advice?

Many mortgage brokers choose not to charge the borrower a fee and operate on a fee-free business model. This is because they are content with the commission received directly from the mortgage lender, after the mortgage application progresses to completion.

This allows them to provide regulated mortgage advice, recommend suitable mortgage products and manage applications without charging the borrower directly.

Whether a mortgage broker charges a fee or operates on a fee-free business model does not determine the quality of the regulated mortgage advice they provide. In many cases, fee-free mortgage brokers can offer the same level of expertise, lender access and application support as brokers that charge a fee.

Ultimately, the decision to charge a borrower fee or operate on a fee-free basis usually comes down to the broker’s business model rather than the standard of advice provided.

Are Mortgage Broker Fees Worth Paying?

While paying for advice does not automatically guarantee a better deal or access to exclusive rates, there are scenarios where the additional cost may be justified.

This usually applies to borrowers who value face-to-face appointments or require additional support for more complex financial circumstances, unusual income structures or specialist lending requirements.

Many fee-free mortgage brokers operate primarily online, allowing them to reduce overheads and rely solely on lender commission rather than charging borrowers directly.

As such, for those who are comfortable receiving advice remotely, choosing a free online mortgage broker can provide the same regulated advice and lender comparisons without the additional cost.

To help you decide whether paying a broker fee is worthwhile, we always advise asking your broker the following questions before agreeing to any charges:

One of the key findings from our study revealed that only 4% of borrowers who paid a mortgage broker fee believed doing so would result in a higher quality service. This highlights the importance of understanding exactly what value a broker fee provides before agreeing to pay it.

Rather than using price as a measure of quality, compare the broker’s expertise, lender access, regulatory status and level of support before deciding whether they are the right broker for your circumstances.

For most straightforward mortgage applications, fee-free mortgage advice may provide everything you need, while paid brokers may offer greater value where specialist knowledge or a more personal face-to-face service is required.

What Is the Cost of Advice vs Going Direct to the Lender?

While paying a mortgage broker fee will increase the upfront cost, it is important to remember that not all advisers will charge for their services.

By using a fee-free mortgage broker, borrowers can receive regulated mortgage advice and lender comparisons without paying an upfront charge. In this way, using a fee-free mortgage broker will naturally cost the same as going directly to a lender, while still providing the advantages of regulated mortgage advice and wider-market lender comparisons.

With that said, the most important consideration when applying directly to a lender is to evaluate what you might gain and what you could be giving up when compared with using the services of a mortgage broker.

Whether you choose to pay for mortgage advice, use a fee-free broker or apply directly to a lender, the differences extend far beyond the initial cost of a mortgage broker fee.

For example, a whole-of-market mortgage broker can compare mortgage products from multiple lenders across the market, assess which lenders’ criteria best match your circumstances and identify the most suitable mortgage for your needs.

The advantage of this wider comparison is that it may help borrowers access more competitive interest rates and lower overall borrowing costs, potentially saving more over the lifetime of a mortgage than applying to a single lender directly.

Ultimately, comparing the cost of a mortgage broker fee vs directly to a bank only tells part of the story. The overall value will always depend on whether you are receiving the most suitable combination of advice, lender choice and support for your circumstances.

Should You Pay a Mortgage Broker Fee?

Now that you understand how broker fees work, the final decision comes down to your own circumstances and the type of support you want throughout the mortgage process.

If your mortgage application involves a highly complicated financial structure, adverse credit or you simply prefer face-to-face support, then paying a broker fee may be worthwhile.

For most borrowers with straightforward mortgage applications, including many first-time buyers, home movers and remortgage applicants, regulated mortgage advice can still be accessed without the need to pay a broker fee.
