The published average monthly interest rate on UK bridging finance was 0.88 percent (Bridging Trends, 2025). It is the number that gets quoted everywhere, and it is close to useless for predicting what any single borrower will pay. An average is the output of thousands of cases with wildly different risk. Your rate is the output of yours. If you want to understand what you will actually be quoted, start with the model, not the average.
We arrange bridging cases every week, so we look at them the way a lender's pricing desk does: as a small set of inputs that push a rate up or down from a base. There are five of them. Understand these and you can predict roughly where you will land before anyone runs a quote, and change the inputs to change the price.
A quick disclosure before the model, because it matters. We are BridgeFinancing, a finance arranger and introducer, not a lender. We are not authorised by the Financial Conduct Authority (FCA). Bridging on investment and commercial security is unregulated commercial lending outside the mortgage perimeter, and where a loan is secured on a borrower's own home it becomes a regulated case that we pass to an authorised firm. Everything below is indicative market data, not our pricing and not an offer.
Variable one: leverage
The first input is how much of the property's value you want to borrow. First-charge bridging typically runs in a band from 55 to 75 percent loan-to-value, and the completed-case average was 60 percent (Bridging Trends, 2025). Where you sit in that band is the single biggest lever on price.
Borrow at the bottom of it and the lender has a thick cushion of your equity absorbing any fall in value, so the risk is low and the rate follows. Push toward the top and that cushion thins, the lender's exposure rises, and the price climbs to match. The last few percentage points of leverage cost disproportionately more, because that is where a lender's recovery gets tight if a sale disappoints. Asking for less is the cleanest way to pay less.
Variable two: charge position
The second input is where the lender sits in the queue if things go wrong. A first charge is repaid first from any sale. A second charge sits behind an existing loan and only gets paid once that first lender is cleared.
That ordering is the whole story on price. A second-charge lender is taking on more risk for the same property, because there is less equity beneath them and less certainty of full recovery. So second-charge bridging prices above an equivalent first charge, every time. It is often still the right tool, when you want to keep a cheap existing facility in place rather than refinance the whole thing, but you pay for the position.
Variable three: the property itself
The third input is what the security actually is. A standard, habitable house in a liquid market is the easiest thing a bridging lender can hold, because if the exit fails they can sell it quickly to a wide pool of buyers. A part-finished development, a property with no kitchen or bathroom, or a specialist asset with a thin resale market is harder to shift and therefore riskier to lend against.
The rate reflects how confidently a lender can turn the security back into cash. Habitable and standard prices best. Non-standard, unfinished or specialist prices higher, and may cap the leverage available too.

Variable four: the exit
The fourth input is the most underrated, and often the most powerful. A bridge is short-term money with a fixed way out, and the average term was 12 months (Bridging Trends, 2025). The lender is really pricing the credibility of your repayment, not just the property.
An evidenced exit is a sale already under offer or a refinance agreed in principle. A hoped-for exit is a plan to sell or remortgage with nothing yet in writing. The first lets a lender commit with confidence and prices accordingly. The second forces them to price in the chance the exit slips, so it costs more, and a genuinely vague exit may not get funded at all. Bringing evidence to the table is free, and it moves the rate more reliably than almost anything else you control.
Variable five: the borrower
The fifth input is you. Experience, credit history and the strength of the wider financial picture all feed the price. A borrower who has completed similar projects before, who has clean credit and who can show the project stands up even if one thing goes wrong is simply less risky to back.
This input tends to have the smallest swing of the five on a well-secured case, because the property and the exit do most of the work. But on a marginal deal it can be the difference between a yes and a no.
Putting the model together
Line the five up and the mechanism is clear. You start near a market base, then each variable nudges the price:
- Leverage: lower LTV pulls the rate down, higher pushes it up.
- Charge position: first charge cheaper, second charge dearer.
- Property: standard and habitable cheaper, non-standard dearer.
- Exit: evidenced cheaper, hoped-for dearer.
- Borrower: experienced and clean cheaper, thin profile dearer.
Four of the five are things you can act on before you ever apply. You can ask for less leverage, choose a first charge where possible, evidence the property position, and above all lock down a documented exit. Do that and you are not at the mercy of an average. You are shaping your own number.
If you want the model run against a real case, that is what an arranger is for. Bring the value, the security, the amount you need and your intended way out, and we will tell you honestly where it prices before you commit.
