Bridging Loans Explained: How They Work, What They Cost, and When to Use One

Bridging loans are one of the most misunderstood products in commercial finance: fast and flexible when used well, expensive if used wrongly. This guide explains what a bridging loan actually is, what it costs, and when it is the right tool for the job.

What is a bridging loan?

A bridging loan is a short term, property secured loan designed to bridge a gap in funding, usually for a few weeks up to 12 to 24 months. It is used when speed matters, or when a property or borrower does not fit a mainstream lender's criteria. The loan is repaid in full at the end of the term from a defined exit, such as a sale or a refinance onto a longer term mortgage.

The key mental shift is that bridging is not a cheaper or faster mortgage. It is a tool for a specific job: getting from A to B when the normal route is too slow or temporarily unavailable. Used for that, it is excellent value. Used as a substitute for term borrowing, it is expensive.

When does bridging finance make sense?

• Auction purchases where completion is required within 28 days.
• Chain breaks, buying a new property before your existing one sells.
• Refurbishment of a property that is not currently mortgageable.
• Time sensitive opportunities where a mainstream mortgage would be too slow.
• Releasing capital quickly against an existing asset.
• Buying below market value, where speed is what secures the discount.
• Lease extensions and title defects, funding the fix so the property becomes mortgageable.

When it does not make sense

Bridging is the wrong answer when there is no clear exit, when the underlying problem is affordability rather than timing, or when a term lender could do the same job with a few more weeks. It is also the wrong answer if the numbers only work on an optimistic sale price. If the exit depends on everything going right, the cost of the bridge is the least of the risks.

Regulated and unregulated bridging

Bridging secured against a property you live in, or intend to live in, is regulated by the Financial Conduct Authority and comes with additional consumer protections. Bridging on investment or commercial property is normally unregulated, which allows more flexibility on structure and speed. Both are legitimate. Knowing which one your case is tells you what protections apply and which lenders can help.

What does a bridging loan cost?

Bridging is priced per month rather than per year, reflecting its short term nature. Costs typically include:

• Monthly interest. Often charged as a monthly rate, commonly in the region of 0.55% to 1.5% depending on the case. Interest can be serviced, retained (deducted upfront), or rolled up and paid at the end.
• Arrangement fee. Commonly around 1 to 2% of the loan.
• Valuation and legal fees. Paid to third parties, and you usually cover the lender's legal costs as well as your own.
• Exit fee. Charged by some lenders on repayment, though many no longer apply one.
• Broker fee. Which should be disclosed in writing before you commit.

Because the headline rate is monthly, always compare the total cost over your expected term, not just the rate. A slightly higher monthly rate with no exit fee and lower legals can easily be the cheaper deal.

How interest is charged

This is worth understanding properly, because it affects how much you actually receive. Serviced interest is paid monthly like a normal mortgage, which needs income to support it. Retained interest is deducted from the advance at the start, so you borrow more than you receive but make no monthly payments. Rolled up interest accrues and is settled with the capital at the end.

Retained and rolled up are the norm on refurbishment cases, where the property produces no income during the works. It also means the loan you need is larger than the cash you require, which surprises borrowers who have budgeted only for the purchase.

Loan to value and exit

Most bridging lenders advance up to around 70 to 75% of the property value, sometimes higher with additional security. The single most important part of any bridging application is a credible, evidenced exit. Lenders want to see exactly how and when they will be repaid. A weak exit is the most common reason bridging deals fall down.

What counts as evidenced varies. A refinance exit is strongest when a term lender has already indicated appetite in writing. A sale exit is strongest with an agent instructed, comparable evidence and a realistic price rather than a hopeful one. Vague answers get either a decline or a much higher price.

How fast can it complete?

Well prepared bridging cases can complete in a matter of days to a few weeks, far quicker than a standard mortgage. Terms are often issued within 24 to 48 hours. Having a valuation, solicitor and clear exit ready in advance makes all the difference.

The most common cause of delay is legal work, not lending. Using a solicitor who has done bridging before, and who has capacity this week rather than next month, is the single biggest thing within your control.

Frequently asked questions

How quickly can a bridging loan complete?

Well prepared cases can complete in seven to ten working days, and faster where there is no valuation delay. Terms are usually available within 24 to 48 hours.

What is an exit strategy?

It is how the loan gets repaid, normally a sale or a refinance onto a longer term mortgage. It is the most important part of any bridging application, because the lender is lending against that repayment.

How much can I borrow on a bridging loan?

Usually up to around 70 to 75% of the property value, and higher where additional security is available. Lenders normally work from the lower of purchase price and valuation.

Do I make monthly payments?

Often not. Interest is commonly retained from the advance or rolled up and settled at the end, which keeps cash free during a refurbishment.

Can I get bridging with bad credit?

Frequently yes, because bridging is security led rather than income led. Adverse credit will affect the rate and the loan to value rather than automatically ruling the case out.

What happens if I cannot repay at the end of the term?

You should speak to the lender early. Some will extend for a fee where the exit is close, but default interest is high and the lender can ultimately take possession of the property. This is why the exit matters more than the rate.

Can bridging be used on commercial property?

Yes, on commercial, semi commercial and mixed use property as well as residential investment. The loan to value is often slightly lower on commercial security.

Is a bridging loan cheaper than development finance?

They do different jobs. Bridging suits purchase and light refurbishment. Development finance suits ground up build and heavy works, with funds drawn in stages against progress. Using bridging for a full development is usually more expensive and riskier.
