Bridging Costs Comparison for UK Property Deals

An auction buyer can see a headline rate that looks manageable, then lose several thousand pounds to arrangement fees, legal costs and interest charged for longer than expected. A proper bridging costs comparison starts with the total amount payable over the likely term, not the monthly rate alone. Bridging finance is short-term, specialist funding. It can protect a purchase, fund a refurbishment or break a property chain, but it is expensive money and only works when the exit is credible.

What a bridging loan really costs

A bridging quote has several moving parts. The interest rate matters, but it is only one part of the price. A lender charging a lower monthly rate may have a larger arrangement fee, higher legal fees or a more conservative valuation approach that reduces the loan available.

Interest is normally quoted monthly rather than annually. On a £300,000 loan, a rate of 0.85% per month means £2,550 interest for each full month outstanding. If the loan runs for six months, that is £15,300 before fees. If the refinance is delayed and the bridge runs for nine months, interest rises to £22,950. The difference is why the exit timetable deserves as much scrutiny as the rate.

LTV, or loan-to-value, also affects the cost. This is the loan divided by the current property value. Lower-LTV cases generally give lenders more security and can access a wider range of pricing. A 65% LTV bridge on a readily saleable house is a different proposition from an 80% LTV facility against a non-standard property requiring heavy works. Neither is automatically wrong, but the latter will normally need stronger evidence on valuation, works, borrower experience and exit.

Interest payment methods change the cash needed

With retained interest, the lender sets aside the projected interest from the gross facility and releases the net advance after deducting it. This reduces the cash you need during the term, but it can reduce what is available for the deposit, works or purchase price.

Rolled-up interest accrues and is added to the balance, then paid when the loan redeems. It can suit a project with no rental income during works, although the accrued debt must remain within the lender’s maximum exposure. Serviced interest is paid each month from your income or rental income. It may preserve more of the initial facility, but lenders will assess whether those monthly payments are affordable.

A comparison should show the gross facility, every deduction and the net amount you will actually receive. The gross loan is not always the money available to complete.

Bridging costs comparison: the charges to put side by side

Ask each lender or broker to show costs on the same assumptions: the same purchase price or valuation, LTV, term, interest method and proposed redemption date. If one quote assumes six months and another assumes 12, they are not directly comparable.

The main costs to compare are:

• Interest: the monthly rate, whether it is charged daily after the first month, and the cost if the loan runs beyond the intended term.
• Arrangement fee: commonly expressed as a percentage of the loan. A 2% fee on £300,000 is £6,000, and it may be deducted from the advance or paid separately.
• Valuation and monitoring: the valuer’s fee is usually paid up front. Refurbishment or development-led cases can also require monitoring surveyor fees and staged drawdown administration.
• Legal, administration and exit fees: you may pay your own legal costs and the lender’s legal costs. Some facilities include an exit fee, usually calculated as a percentage of the loan or gross facility.

There may also be broker fees, title indemnity costs, asset manager fees on complex security, drawdown fees, transfer fees and default interest. Default interest is not a routine cost to budget as if it were ordinary pricing. It is a serious consequence of breaching the facility terms, including failing to repay on time.

A useful comparison separates unavoidable third-party costs, such as valuation and solicitors, from lender charges and advisory fees. It also identifies which sums are payable up front and which are deducted from the loan. Cash flow often decides whether a structure is workable.

Compare the net advance, not just the headline facility

Suppose you need £240,000 to complete a purchase and cover immediate works. Lender A offers a £300,000 gross facility at 0.79% per month with a 2% arrangement fee and six months of retained interest. Lender B offers £300,000 at 0.89% with a 1% fee and serviced interest. Lender A may look cheaper on rate, but its retained interest and fee could leave a lower net advance. Lender B could release more cash on day one, provided you can service the monthly interest.

This is particularly relevant for auction purchases. A traditional auction contract normally requires completion within 20 working days, while Modern Method of Auction commonly allows around 56 days. Either timetable can be too tight for a standard mortgage, especially where the property is unmortgageable at purchase. The cheapest bridge is of little use if valuation, underwriting and solicitors cannot complete within the contractual deadline.

For refurbishment projects, check whether works money is advanced in one payment or through staged drawdowns. Staged drawdowns can control cost and support a higher overall facility, but each release may need evidence of progress, invoices or a monitoring surveyor’s sign-off. That can affect the programme as well as the finance cost.

The exit is where the real comparison is won or lost

A bridge should be priced against its exit strategy. The usual exits are sale, refinance to a buy-to-let or residential mortgage, sale of another property, or repayment from a confirmed transaction. Each route has different risks.

If the exit is refinance, assess it before taking the bridge. Will the property be mortgageable after works? Is the anticipated rental income sufficient for the buy-to-let stress test? For a homeowner, does income support the planned residential remortgage? If you intend to refinance from a limited company or SPV, the lender and product must fit that ownership structure.

A low purchase price does not by itself make the exit safe. Lenders will look at the current value, the anticipated value after works where relevant, comparable evidence, scope of works, timescales and the route to repayment. On development exit finance, they may also assess GDV, or gross development value, unit sales, unsold stock and any existing development debt. Day-one LTV is the leverage against today’s value, while GDV-based lending considers the anticipated completed value. They answer different questions and should not be treated as interchangeable.

From our experience arranging specialist property finance, cases most often stall because the exit was discussed in broad terms rather than evidenced. Underwriters regularly query a valuation that does not support the expected refinance figure, planning or building regulation gaps, a missing schedule of works, unexplained adverse credit, or a company structure that does not match the application. These are not necessarily deal-breakers. They become problems when they appear late, after legal work and deadlines have already started.

When a second charge may be the better comparison

For homeowners and landlords with a low fixed rate on their first mortgage, remortgaging everything to raise capital can be unnecessarily expensive. An early repayment charge, or ERC, on the first mortgage may outweigh the apparent benefit of a new blended rate. A second charge mortgage can raise funds while leaving the first mortgage in place.

A second charge sits behind the existing first-charge lender in priority. The first lender may need to give consent to the second charge, and affordability is assessed across both commitments. It adds another loan secured against the property, so it is not a lighter decision than a remortgage. However, for home improvements, business capital, debt consolidation or landlord investment, it can be more cost-effective than replacing a favourable first-charge deal.

The right comparison is therefore not simply bridge versus bridge. It may be bridge versus second charge, remortgage, development facility or waiting until a property is mortgageable. The best route depends on urgency, security, affordability, the property condition and how certain the exit is.

Before committing, ask for a written illustration that shows the loan amount, net advance, all fees, interest method, total estimated cost at your likely redemption date and cost if the exit slips. A regulated adviser should also test the proposed repayment route rather than treating it as a box to tick. That preparation gives you a better chance of completing quickly without discovering the real price after funds have been committed.

Lending is subject to status, valuation and lender criteria. Unregulated bridging, buy-to-let and most development finance are not regulated by the Financial Conduct Authority.
