Comparing bridging loan deals in the UK means weighing up more than the headline interest rate. You need to look at arrangement fees, exit fees, loan-to-value, how quickly a lender can actually complete, and whether the exit strategy they'll accept matches your plan. Get any one of those wrong and the cheapest-looking deal on paper can end up the most expensive, or the one that falls over entirely.
What this means in practice
Comparing bridging loan deals differs from comparing mortgages because the numbers move faster and the small print carries greater weight. A rate that looks 0.2% cheaper a month can be wiped out by a higher arrangement fee, a minimum term clause, or an exit fee you weren't expecting.
We see clients every week who've gone straight to the lender with the lowest advertised rate, only to find the real cost of the deal is higher once fees, valuation costs and legal charges are added in. The only way to properly understand how bridging loans work is to work out the total cost of the loan over its actual expected term, not just the monthly rate quoted on a lender's website.
Bridging loans are typically priced monthly rather than annually, which catches a lot of borrowers out. A rate of 0.75% a month sounds low until you realise that over six months it's roughly 4.5%, and that's before fees. Compare that to a competitor at 0.85% a month with a lower arrangement fee and no exit fee, and the second deal might actually work out cheaper depending on how long you need the money for. For current pricing information, see this guide to bridging loan rates across the UK.
To make this concrete, take a £250,000 bridging loan needed for six months. At 0.75% a month with a 2% arrangement fee, you're looking at roughly £11,250 in interest plus £5,000 in fees, giving a total cost of around £16,250 before valuation and legal costs. At 0.85% a month with a 1% fee and no exit charge, the interest comes to about £12,750 plus £2,500 in fees, a total of £15,250. The second deal, despite the higher headline rate, is actually £1,000 cheaper over that term.
This is exactly why we always ask clients how long they realistically expect to need the loan before we start comparing lenders. A deal that's cheaper over three months might be the more expensive option over nine, simply because of how the fees and rates interact. Getting this wrong is one of the most common and costly mistakes we see borrowers make when they compare deals themselves.

Arrangement fees and how they affect the real cost
Arrangement fees on UK bridging loans usually sit between 1% and 2% of the gross loan amount. On a £300,000 loan, that's anywhere from £3,000 to £6,000 added straight onto the cost before a single month of interest has been charged. Some lenders will let you add this fee to the loan itself, which helps cashflow but increases the amount you're paying interest on.
Always check whether the arrangement fee is calculated on the gross loan or the net amount you actually receive. On a retained interest deal, this distinction can make a noticeable difference to the real cost, and lenders rarely spell this out clearly in their initial illustrations. Ask for the figure in writing before you commit to anything.
Exit fees, minimum terms and loan-to-value
Exit fees are less common than they used to be but they still catch people out. Some lenders charge 1% of the loan on exit, others charge a flat fee, and a few charge nothing at all. If you're comparing two deals with similar rates, the presence or absence of an exit fee can be the deciding factor, especially on larger loans where 1% might mean several thousand pounds.
Some lenders also apply a minimum term charge, sometimes called an early repayment fee, which means you'll pay interest for a set minimum period even if you repay the loan early. If your exit strategy involves a quick sale that might complete in eight weeks rather than the six months you've applied for, this clause could cost you far more than a slightly higher advertised rate elsewhere.
Loan-to-value is another area where headline figures can mislead. A lender offering 75% LTV sounds generous until you discover they've valued the property conservatively, effectively reducing the amount you can actually borrow. Always ask how the valuation will be conducted and whether the lender uses their own panel of surveyors or accepts an independent valuation you've already commissioned.
Ask also whether the LTV is based on the current market value or the projected value after any works are completed. For refurbishment short-term property finance, some lenders will lend against gross development value, which can significantly increase what you're able to borrow compared to a lender who only lends against the property's value as it stands today.
Speed of completion and exit strategy
Speed of completion varies enormously between lenders, and comparison tables often fall short because they only show cost, not timescale. Some specialist bridging lenders can complete in seven to ten days if the case is straightforward and the legal work moves quickly. Others, particularly those requiring more extensive underwriting or committee approval, can take four to six weeks even when they've quoted a fast turnaround.
If your bridging loan is funding a time-sensitive purchase, such as securing a property at auction or beating a chain collapse, the cheapest rate is worthless if the lender can't complete in time. We've had clients lose deposits because they chose a marginally cheaper lender who then couldn't meet the completion date they'd promised. This applies whether you're arranging bridging loans in London, bridging loans in Birmingham, bridging loans in Norwich, or bridging loans in Reading, as local solicitor relationships and valuation panels can all affect timescales.
One practical way to compare timescales is to ask each lender for a realistic completion date in writing, not a marketing claim. Ask specifically about their track record on cases similar to yours, and ask whether their legal team works with your solicitor regularly. A lender who already has a relationship with your conveyancer can often shave several days off the process.
Exit strategy acceptance is probably the most overlooked part of comparing bridging deals. Every lender has different appetite for how you plan to repay the loan, whether that's selling the property, refinancing onto a term mortgage, or using proceeds from another transaction. Some lenders are comfortable with a sale as the sole exit, others insist on seeing a mortgage offer in principle already in place before they'll lend.
Ask each lender directly what evidence they'll need of your exit strategy at application stage versus what they'll want to see before completion. A lender who's flexible early on but strict later can leave you scrambling for paperwork at the worst possible time, right when you're trying to complete the deal.
Regulated lending, interest structures and second charges
Regulated versus unregulated bridging loans is another distinction that affects how you compare deals. If the loan is secured against a property you or a family member will live in, it's likely to be regulated by the FCA, which brings additional consumer protections but can also mean slower underwriting. Unregulated bridging, typically used for investment or commercial property, tends to move faster but with fewer built-in protections.
Interest can be structured in three ways on a UK bridging loan: paid monthly, deducted from the loan upfront (retained), or rolled up and paid at the end. Retained interest reduces your monthly outgoings but also reduces the net amount you receive from the loan, which matters if you're working to a tight budget on a refurbishment or purchase.
Rolled up interest, sometimes called compounded interest, means the interest is added to the loan balance each month and you pay it all off along with the capital at the end. This tends to suit borrowers who need every penny of the gross loan upfront but be aware that it means you're paying interest on interest, which can add up faster than a retained or serviced structure over longer terms.
Second charge bridging loans, where you're borrowing against a property that already has a mortgage on it, tend to come with slightly higher rates and more restrictive LTV caps than first charge lending. If you're comparing a first charge deal against a second charge one, don't assume they're directly comparable without adjusting for that risk difference. For a closer look at how different providers stack up, this roundup of leading bridging loan lenders in the UK is worth reading.
You should also check whether the existing first charge lender needs to give consent for a second charge loan to be secured, as this step alone can add days or even weeks to a timeline if it's not sorted out early. Some lenders will chase this on your behalf, others expect you or your broker to manage it, so it's worth clarifying at the outset.
Building a total cost comparison
When you're weighing up two or three quotes side by side, it helps to build a simple total cost comparison rather than relying on the headline rate alone. Add together the arrangement fee, expected interest over your realistic timeframe, exit fee if applicable, valuation fee, and legal costs, then compare that total figure across each lender's offer.
A basic spreadsheet with these five columns for each lender, arrangement fee, monthly rate multiplied by expected months, exit fee, valuation cost, and legal fees, will give you a genuine like-for-like figure. It takes about twenty minutes to put together properly and it's the single most useful thing you can do before signing an offer letter.
Broker fees are worth factoring in too, though a good broker should save you more than they cost through better rate negotiation and faster access to the right lender. At Boxx Finance, we're often able to get preferential terms from lenders we have strong relationships with, which can offset any broker fee several times over on a typical loan size.
Ultimately, the right bridging loan isn't always the cheapest one on paper, it's the one that completes on time, matches your exit plan, and doesn't leave you with unexpected costs at the end. Taking an hour to properly compare total costs and lender flexibility before you commit can save thousands of pounds and a lot of stress further down the line.
