What Is the Total Cost of a UK Bridging Loan, Including All Fees?

The monthly interest rate is the number everyone quotes first, and the number that tells you the least about what a bridging loan will actually cost. Interest is just one line in a bill that typically includes several other costs, and the only way to genuinely compare two bridging quotes is to add every single one of them together.

Bank of England held base rate at 4.25% in June 2026 - waiting for inflation to cool.

73% of UK SMEs expect to grow in the next 12 months - confidence remains strong.

What actually makes up the total cost?

A typical UK bridging loan involves several distinct costs, layered on top of each other:

Interest

Charged monthly, typically somewhere between 0.5% and 1.5% per month depending on the specific deal, structured as retained, rolled-up, or serviced interest. This is usually the largest single cost, and it scales directly with how long the loan runs.

Arrangement fee

Typically around 2% of the loan amount, charged by the lender for setting up the facility. Some lenders allow this to be added to the loan rather than paid upfront, which reduces the immediate cash outlay but slightly increases the overall borrowing.

Valuation fee

Covers the cost of a surveyor formally valuing the property, required by the lender before funds are released. This varies depending on the property’s value and complexity, more unusual or higher-value properties typically cost more to value.

Legal fees

Bridging loans require legal work on both sides, your own solicitor, and typically the lender’s solicitor too, with the borrower often covering both sets of costs. Commercial and bridging legal work tends to cost more than standard residential conveyancing, reflecting the more involved nature of the transaction.

Broker fees, where applicable

Some brokers charge a fee for arranging the loan, though a genuine no-upfront-fee model means many cases can be arranged without this cost falling on the borrower directly.

Exit fees, with some lenders

Not universal, but some lenders charge a fee when the loan is repaid, worth checking specifically before signing anything, since this can catch borrowers out if it isn’t factored into the total cost calculation from the outset.

What does this look like in a worked example?

Take a £300,000 bridging loan, running for 6 months, at 0.75% per month interest, with a 2% arrangement fee:

• Interest: £300,000 × 0.75% × 6 months = £13,500
• Arrangement fee: £300,000 × 2% = £6,000
• Valuation fee: typically a few hundred to a couple of thousand pounds, depending on the property
• Legal fees: often somewhere in the region of £1,500-£3,000 across both sides, depending on complexity

Added together, the total cost of this facility could realistically sit somewhere in the region of £21,000-£25,000 across the six-month term, considerably more than the headline interest figure alone would suggest.

Why does the loan term matter so much to the total cost?

Because interest is charged monthly, the total cost scales directly with how long the facility is outstanding. The same £300,000 loan running for 12 months instead of 6 would roughly double the interest cost, while the arrangement, valuation, and legal fees stay largely fixed regardless of term. This is exactly why an unnecessarily extended bridging term quietly becomes expensive, and why having a clear, realistic exit strategy matters as much for cost control as for the lender’s own risk assessment.

Does the interest structure affect the total cost?

Not dramatically in principle, retained, rolled-up, and serviced interest are different ways of timing the same underlying cost rather than fundamentally different prices. What differs is cash flow, retained and rolled-up structures mean no monthly outgoings during the term, while serviced interest means paying monthly but potentially reducing the final amount owed at completion.

What affects where your specific total cost lands?

A number of factors move the overall figure:

• Loan-to-value. Lower LTV typically earns a lower interest rate, reducing the largest cost component.
• Property type and condition. Standard, straightforward properties generally cost less to value and legally process than unusual or complex ones.
• Credit profile. Adverse credit tends to push the interest rate towards the higher end of the range.
• Loan term. Shorter terms reduce total interest cost, provided the exit strategy is realistic and achievable within that timeframe.
• Lender-specific fee structures. Arrangement fees, exit fees, and whether legal costs are shared or borne entirely by the borrower all vary between lenders.

How can you actually calculate this before applying?

Rather than estimating manually, Money Pilot experts help borrowers model the total cost of a bridging facility directly, interest across the expected term, arrangement fees, and other associated costs, before committing to any specific lender, giving a genuine, comparable total cost figure rather than relying on a headline monthly rate alone.

The mistake borrowers often make

Some borrowers compare bridging quotes purely on the advertised monthly interest rate, without adding in arrangement fees, valuation costs, legal fees, and any exit charges. A quote with a slightly lower interest rate but higher fees elsewhere can end up costing more overall than one with a marginally higher rate but more competitive fees across the rest of the facility.

The bottom line

The total cost of a UK bridging loan includes considerably more than the headline monthly interest rate, arrangement fees, valuation costs, legal fees, and sometimes exit fees all add to the final figure, and the loan term itself scales the interest cost directly. Comparing quotes properly means adding every one of these together, not judging a single percentage in isolation. Money Pilot’s calculator and content are built specifically to surface that full total cost picture, helping borrowers understand exactly what a bridging facility will cost before committing to it.
