To clarify, this study purposely does not include borrowers who opted for a fee-free broker, as the focus is on those borrowers who decided to pay a broker fee.

Average Mortgage Broker Fees for Purchases

The data below relates to the mortgage broker fees charged for residential property purchases. For the avoidance of doubt, data was not collected on the broker fees charged for commercial or buy-to-let purchases.

Average Purchase Broker Fee

The average purchase broker fee was £643.00. This figure is weighted across all participants, based on 1,000 responses. Compared to our study from 2025, where £500.00 was the average, this represents a 28.6% increase in broker fees charged.

Most Common Fee Charged

The research confirms that £500.00 was the most popular mortgage broker fee selection, followed by £700.00 and £600.00. Although the difference between the £700.00 and £600.00 selections was marginal. Fewer than 10% of participants were charged £300.00 or less.

Most Common Fee Charged – Residential Purchases

After reviewing the data, it’s clear that mortgage broker fees of £300.00 or less for purchase cases are uncommon.

As the majority of participants paid between £500.00 and £700.00 (56%). This suggests a clear pricing concentration within the purchase market.

When comparing these results to our Average Mortgage Broker Fee study in 2025, the average purchase broker fee has significantly increased in just one year.

When the Broker Fee was Charged

Respondents were asked when a mortgage broker fee was charged during their purchase transaction.

The most popular selection (46%) confirmed that their broker fee was charged after the mortgage offer was issued but before the transaction completed.

The second most popular selection (27%) confirmed that the broker fee was charged after the mortgage application was submitted, but before the mortgage offer was issued. This proportion is significantly higher than the equivalent figure for remortgage transactions (12%).

Just 15% of respondents were charged a broker fee for their purchase application before the mortgage application was submitted.

Type of Broker Fee Charged

The data below showcases the type of mortgage broker fee charged to participants.

The most popular selection was a fixed fee (44%), followed by a percentage of the loan (29%) and a percentage of the property value (19%). Just 7% of respondents were charged a split fee, where the broker fee was divided across multiple stages of the purchase transaction.

These results closely mirror those reported by remortgage respondents, suggesting brokers do not materially alter their fee structure between purchase and remortgage cases.

Rationale for Paying a Broker Fee

As all participants paid a mortgage broker fee, they were asked for their primary reason for not selecting a fee-free broker.

You can view the full list of options available to participants in the research file.

The most popular selection was: “I was unaware that fee-free mortgage brokers can have the same access to mortgage lenders and products as fee-charging brokers.” 31% of respondents selected this option.

The second most popular option was “I was unaware that a fee-free, whole-of-market, mortgage broker was an option”, with a 20% selection.

The third most selected option was “I used the fee-charging mortgage broker affiliated with the estate agent”, selected by 12% of respondents.

Only 4% believed they would receive a higher quality service by using a fee-charging broker.

As showcased in the same data below for respondents who remortgaged, the primary reasons for respondents opting for a fee-charging broker are due to them being unaware that fee-free brokers exist or due to a misconception regarding mortgage product access.

Conclusion

The average mortgage broker fee charged in the UK for purchase and remortgages has increased significantly in the past 12 months – to £643.00 and £623.00 respectively.

£500.00 remains the most common fee across both purchase and remortgage transactions, with consistent representation across regions.

Brokers are increasingly charging fees later in the mortgage process, with the majority collecting fees after the full mortgage application stage.

Like last year, respondents chose a fixed broker fee as their most popular fee type.

The majority of participants opted for a fee-charging broker because they were either unaware that fee-free alternatives exist, or they believed that fee-charging brokers have greater mortgage access.

This study highlights clear information asymmetry for mortgage borrowers choosing a mortgage broker. Consumers should be made aware that fee-free mortgage brokers exist and that a broker’s decision to charge a fee is unrelated to their mortgage product access.

The findings suggest that consumers need more education on mortgage broker operations, their fee structures, and product access. This will enable them to make more informed decisions to suit their circumstances.
