The True Cost of Short-Term Property Finance in London

Cost of Short-Term Property Finance in London

Bridging loan costs in London vary significantly depending on the property value, location, loan-to-value ratio, and the complexity of the transaction. A straightforward residential bridge on a Clapham terraced house will cost considerably less than a complex offshore structure for an ultra-prime acquisition in Mayfair or Knightsbridge. This guide breaks down every cost component so you can calculate the true expense of a London bridging loan before you commit.

The Components of a London Bridging Loan Cost

A bridging loan is not a single cost — it is a bundle of charges from different parties. Understanding each component allows you to compare lender offers on a like-for-like basis and avoid surprises at completion.

Monthly Interest Rate

The headline cost. London bridging loan interest rates typically range from 0.45% to 0.95% per month, depending on the property type, LTV, and borrower profile. Prime residential property in areas like Belgravia, Chelsea, and Kensington at conservative LTV (under 60%) attracts rates at the lower end — from 0.45% per month. Higher LTV facilities, properties in less established areas, or more complex transactions (offshore structures, adverse credit, unmortgageable properties) sit at the higher end.

Interest is almost always “rolled up” — meaning it is added to the loan balance rather than paid monthly. This means you make no payments during the bridge term, but the total interest cost is higher because you are effectively paying interest on interest. On a £1 million bridge at 0.65% per month held for 9 months, the rolled-up interest cost would be approximately £58,500.

Arrangement Fee (Facility Fee)

Charged by the lender for setting up the facility. Typically 1-2% of the gross loan amount. On a £500,000 bridge, a 2% arrangement fee is £10,000. Some lenders offer lower arrangement fees but charge higher monthly rates — always compare the total cost of the facility over the expected term, not just the headline rate or the arrangement fee in isolation.

Valuation Fee

The lender instructs an RICS-accredited surveyor to value the property. Costs vary by property value and type. Standard residential valuations in areas like Balham, Tooting, Fulham, or Islington typically cost £500-£1,000. Prime and ultra-prime valuations in Hampstead, Highgate, Holland Park, or St John’s Wood cost £1,000-£2,500 due to the complexity of valuing high-value period properties. Commercial and mixed-use property valuations cost £1,500-£3,000+. Some lenders accept desktop valuations (£150-£300) for lower LTV residential cases, which significantly reduces this cost and speeds up the process.

Legal Fees

You will pay your own solicitor’s fees and the lender’s solicitor’s fees. Borrower’s solicitor: £1,500-£3,000 for a standard residential bridge. Lender’s solicitor: £1,000-£2,500. Some lenders use a single solicitor to act for both parties (a “dual representation” arrangement), which can reduce total legal costs to £2,000-£3,500. Complex transactions — offshore structures, multiple securities, leasehold properties with title issues — will cost more.

Broker Fee

At Platinum Global we charge no broker fee on facilities of £500,000 or above. For smaller facilities, a broker fee of 0.5-1% of the loan may apply. Not all brokers operate on this basis — some charge 1-2% regardless of facility size — so it is worth confirming the fee structure upfront.

Exit Fee

Some lenders charge an exit fee (also called a redemption fee) when the loan is repaid. This is typically 1-1.25% of the loan amount. Not all lenders charge exit fees — we prioritise lenders with no exit fees wherever possible, as this can save thousands on the total cost.

Worked Cost Examples by London Area

The following examples illustrate how bridging costs vary across different London markets. All examples assume interest rolled up, no exit fee, and standard legal and valuation costs.

Example 1: Crouch End Victorian Terrace — Chain Break

A family purchases a 4-bed Victorian terrace in Crouch End for £1,100,000 while their existing Stoke Newington flat is still on the market. They need a chain break bridging loan.

Loan: £770,000 (70% LTV). Rate: 0.60% per month, rolled up. Term: 6 months (expected time to sell existing property). Interest: £27,720. Arrangement fee at 1.5%: £11,550. Valuation: £800. Legal fees: £3,000. Total bridging cost: £43,070 — representing 3.9% of the purchase price.

Example 2: Bermondsey Warehouse Conversion — Refurbishment

An investor purchases a warehouse unit in Bermondsey for £650,000 requiring £150,000 of conversion works to create a 2-bed apartment. Post-works value estimated at £950,000.

Loan: £455,000 purchase (70% LTV) plus £150,000 works = £605,000 total facility. Rate: 0.70% per month on drawn funds, rolled up. Average drawn balance over 10 months: £530,000. Interest: £37,100. Arrangement fee at 2%: £12,100. Valuation: £800. Legal fees: £3,500. Total bridging cost: £53,500 — against a projected profit of approximately £146,500.

Example 3: Wimbledon Village Family House — Bridge to Mortgage

A buyer purchases a detached house near Wimbledon Common for £3,200,000, bridging to a private bank mortgage from Coutts that will take 4 months to complete.

Loan: £2,240,000 (70% LTV). Rate: 0.50% per month, rolled up. Term: 4 months. Interest: £44,800. Arrangement fee at 1%: £22,400. Valuation: £1,500. Legal fees: £5,000. Total bridging cost: £73,700 — representing 2.3% of the purchase price.

Example 4: Hackney HMO Conversion — BRRR Strategy

An investor purchases a large Victorian house in Hackney for £750,000 and converts it into a 6-room HMO. Conversion costs: £65,000. Post-conversion HMO value: £950,000. Monthly rental income: £4,200.

Loan: £562,500 purchase (75% LTV) plus £65,000 works = £627,500 total. Rate: 0.70% per month, rolled up. Average drawn balance over 8 months: £595,000. Interest: £33,320. Arrangement fee at 2%: £12,550. Valuation: £900. Legal fees: £3,000. Licensing: £800. Total bridging cost: £50,570 — against a projected equity gain of approximately £200,000 and annual rental income of £50,400.

How to Reduce Your London Bridging Loan Costs

Borrow at Lower LTV

The single biggest lever on cost. A 50% LTV bridge will attract significantly lower rates than a 75% LTV facility on the same property. If you can contribute a larger deposit or offer additional security, the rate reduction can save tens of thousands on a London-scale transaction.

Choose Lenders with No Exit Fee

Exit fees of 1-1.25% add significant cost — £10,000-£12,500 on a £1 million facility. We prioritise no-exit-fee lenders across our panel of 100+ lenders.

Repay Early

Most bridging loans have no early repayment charges. If your exit strategy (sale, refinance, or mortgage) completes ahead of schedule, you stop paying interest immediately. On a £1 million bridge at 0.65% per month, every month saved is £6,500.

Use a Desktop Valuation Where Possible

For lower LTV residential bridges in established areas like Richmond, Putney, Greenwich, or Barnes, a desktop valuation (£150-£300) may be accepted instead of a physical survey (£500-£1,500+). This saves money and 1-2 weeks on the timeline.

Negotiate the Arrangement Fee

Arrangement fees are negotiable, particularly on larger facilities. On a £2 million+ bridge, the difference between a 1.5% and a 2% arrangement fee is £10,000. We negotiate arrangement fees as part of every placement.

How London Bridging Costs Compare to Other Finance Options

Bridging is more expensive than a conventional mortgage on a monthly basis — but it provides something a mortgage cannot: speed and certainty. A standard residential mortgage in London takes 6-12 weeks to complete. A bridging loan completes in 10-14 working days, or as fast as 5-7 days for urgent cases. In a competitive London market where properties in Notting Hill, Primrose Hill, Battersea, and Dulwich Village attract multiple offers within days, the ability to exchange quickly can be the difference between securing and losing a property. The bridging cost should be weighed against the potential cost of losing the property entirely — or being forced to accept an inferior alternative.

For refurbishment projects across Camden Town, Brixton, Peckham, Stratford, and Walthamstow, bridging is often the only option — conventional lenders will not lend on unmortgageable properties. The bridging cost is a project expense that enables the value-add strategy, not an avoidable overhead.

Frequently Asked Questions

What is the cheapest bridging loan rate in London?

The lowest rates we currently access are from 0.45% per month for prime residential London property at 50-60% LTV. This is available on properties in established prime areas — Mayfair, Belgravia, Chelsea, Kensington, Knightsbridge, and similar — where the property is in good condition and the borrower has a strong profile.

Are bridging loan costs tax deductible?

For investment properties, bridging loan interest and fees are generally allowable expenses against rental income or can be offset against capital gains. For properties held in a limited company, all finance costs are deductible against corporation tax. Always confirm with your accountant, as tax treatment depends on the specific circumstances of the transaction.

Do I need to make monthly payments?

No. Most London bridging loans offer rolled-up interest, meaning no monthly payments are required. The interest accrues and is repaid along with the capital when the loan is redeemed. This is particularly useful for refurbishment projects where the property is not generating income during the works period.

How much deposit do I need for a London bridging loan?

Typically 25-30% of the property value (for 70-75% LTV). On a £1 million London property, this means a deposit of £250,000-£300,000. Lower deposits (higher LTV) are available with additional security or for experienced borrowers with strong track records.

Can I add the bridging costs to the loan?

The arrangement fee and interest are typically added to the loan (rolled up). Valuation and legal fees are usually paid upfront out of your own funds, though some lenders will add these to the facility on lower LTV cases.
