What is a bridging loan and how do they work?

So, what is a bridging loan once you look past the definition? In practice, it works by giving a lender security over your property in exchange for fast access to funds. Here's the mechanism, in outline.

The lender places a legal charge on the property you're using as security, either the one you're buying or one you already own. Once that charge is registered and the valuation and legal checks are complete, the lender releases the loan, often within days rather than the weeks a standard mortgage takes. Some lenders can turn around an urgent case in as little as 24 to 48 hours, though a week or two is more typical once you allow for a proper valuation and legal work.

You then repay the full amount, plus interest and fees, when your exit strategy completes. An exit strategy is simply your plan for how you'll repay the loan, such as selling a property, remortgaging onto a standard rate, or refinancing to another lender. Lenders will usually ask you to evidence this plan before they agree to lend, rather than taking your word for it.

Interest is usually charged monthly, and many lenders let you "roll up" the interest so you make no monthly payments during the term, adding it to the balance instead. Some lenders offer a "retained" option, where the interest for the full expected term is deducted from the loan upfront, or a "serviced" option, where you pay the interest monthly as you would on a standard loan. Which option suits you best depends on whether you have income available to cover monthly payments during the term, or whether you'd rather the cost is settled in one go when your exit strategy completes.

Because the loan is secured against property, your home or other secured asset could be repossessed if you don't keep up repayments or your exit strategy falls through. This guide focuses on the fundamentals. For the full step-by-step process, including valuation, underwriting, and legal completion, see the full step-by-step bridging loan process.

Bridging loans are flexible, but they're built for time-sensitive situations rather than everyday borrowing. Here are the most common scenarios where people use one, including using a bridging loan to buy before you sell and, for business owners, bridging finance for business and commercial property.

Not all bridging loans work the same way. Three distinctions matter most: whether the loan is open or closed, whether it's a first or second charge, and whether it's regulated or unregulated. Understanding these affects how quickly you can be approved and what consumer protections apply.

The regulated vs unregulated distinction matters most for approval speed and your protections if something goes wrong. Regulated bridging loans involve more affordability checks, which can slow things down slightly, but they also come with stronger consumer protections and access to the Financial Conduct Authority complaints process. You can check any firm's authorisation on the Financial Conduct Authority register. Unregulated bridging loans, more common for investment or commercial property, tend to move faster because fewer affordability checks are required, but you have less recourse if a dispute arises. For a closer look at what this means in practice, see our guide to regulated vs unregulated bridging loans explained.

Most lenders offer combinations of these categories rather than a single fixed product. For example, a closed, first charge, regulated bridging loan might suit someone who has exchanged on a sale and needs to complete a purchase before it finishes. An open, second charge, unregulated bridging loan might suit an investor raising capital against a property they already own, with no fixed sale date in mind. Your advisor or lender will help you identify which combination fits your circumstances.

Bridging loans cost more than mainstream mortgages, reflecting their speed and flexibility. Rather than a single headline rate, you're likely to come across several separate charges:

• Arrangement or facility fee - typically a percentage of the loan amount, charged for setting up the facility
• Monthly interest - charged monthly rather than as an annual rate, and often retained, serviced, or rolled up depending on the lender and your preference
• Valuation fee - covers the lender's assessment of the property used as security
• Legal fees - for both your solicitor and the lender's solicitor, since a legal charge needs to be registered
• Exit fee - some lenders charge a fee when the loan is repaid, though not all do

Exact pricing varies by lender, loan-to-value, and your risk profile, so it's worth comparing more than one quote. For current bridging loan costs and fees matched to your circumstances, speak to an advisor. You can also get an instant bridging loan cost estimate before you apply.

Bridging lenders assess your application differently to a mainstream mortgage lender. Rather than focusing mainly on income, they look closely at the property you're securing the loan against and how you plan to repay it. There's no fixed minimum deposit for a bridging loan in the way there is for a mortgage, but you'll generally need enough equity to keep the loan within a lender's maximum loan-to-value, commonly around 70-75%. For example, on a property worth £300,000, a lender capping borrowing at 70% loan-to-value would lend up to £210,000, meaning you'd need £90,000 in equity or deposit to cover the rest.

Credit history is considered in context rather than as an automatic bar. Bridging lenders are typically more flexible than mainstream mortgage lenders on past credit issues, such as missed payments, defaults, or even a County Court Judgment, provided your exit strategy and security are strong. This is one reason bridging finance appeals to borrowers who wouldn't currently pass a mainstream mortgage lender's affordability checks, though it isn't a substitute for a mortgage and shouldn't be treated as one long-term.

Age, employment status, and income still play a part, but they carry less weight than they would with a standard mortgage application. Self-employed borrowers, contractors, and those with complex income are generally assessed on the same basis as anyone else, since the lender's main concern is the strength of the security and the exit plan.

A bridging loan isn't always the right tool. Depending on your timeline and circumstances, a standard mortgage, a secured loan, or even a personal loan might serve you better and cost less. Here's how the main options compare.

A bridging loan tends to be the right tool only when speed matters more than cost and you have a genuinely reliable exit strategy. If you can wait a few weeks and don't have a pressing deadline, a standard mortgage or a secured loan will usually work out cheaper over time.

A remortgage or further advance can also be worth considering if you already own the property and simply need to release equity, rather than complete a purchase against a deadline. This route generally takes longer to arrange than a bridging loan, but it avoids the higher short-term costs. A personal loan can suit smaller, unsecured borrowing needs, though lenders typically cap these well below what most bridging cases require, and it won't be secured against your property.

In practice, most people who genuinely need a bridging loan already know why a mainstream alternative won't work for their timeline. If you're not sure which category you fall into, it's worth talking through your situation and exit strategy with an advisor before assuming a bridging loan is your only option.

The main downsides of a bridging loan are cost, risk, and the pressure of a short deadline. Interest and fees are considerably higher than mainstream mortgages or secured loans, reflecting the speed and flexibility on offer. Your home may be repossessed if you do not keep up repayments on a mortgage or any other debt secured on it, and because bridging loans are secured against property, this risk applies directly if you can't repay the loan or your exit strategy fails.

Short terms also mean less room to recover from a delay. If a sale falls through or a refinance application is declined, you have far less time to find another solution than you would with longer-term borrowing. Rolled-up interest is another factor to weigh carefully: because it compounds monthly and is added to your balance rather than paid off, the amount you owe grows steadily throughout the term, even though you're not making any payments in the meantime.

Bridging loans also depend heavily on property market conditions holding up. If values fall or a sale takes longer than expected, the amount raised from a sale might not be enough to clear the loan in full, leaving you needing to find the shortfall from elsewhere.

What happens if your exit strategy fails?

If your exit strategy doesn't complete on time, most lenders will consider extending the facility, usually at a higher rate. Some borrowers refinance to another bridging lender instead. If neither is possible and the loan remains unpaid, the lender can ultimately force a sale of the secured property to recover what's owed. This is why lenders, and advisors, place so much weight on your exit strategy being realistic before the loan is agreed, and why it's worth having a backup plan in place before you commit.
