Bridging Loan Costs: A Full Breakdown for 2026

A bridging loan is a short-term secured facility designed to bridge a financial gap — typically until a property is sold, a mortgage completes, or a development is refinanced onto longer-term debt. Unlike a conventional mortgage, where costs spread across decades, bridging costs concentrate into a short window of six to eighteen months. That concentration is precisely what makes understanding the full picture so important before you draw down.

The total cost of a bridging loan breaks into three main components: monthly interest on the outstanding balance, a set of one-off fees charged at arrangement and completion, and legal costs on both sides of the transaction. Every element is negotiable to a degree, and the combination varies considerably between lenders and deal types.

To illustrate, a commercial bridging loan of £500,000 arranged for nine months at 0.75% p.m. carries gross interest of £33,750. Add a 2% arrangement fee (£10,000), a valuation (circa £1,200), and dual legal costs (circa £3,500 combined), and the total cost of funds approaches £48,450 — approximately 9.7% of the loan value. That is materially higher than a term mortgage, which reflects the speed, flexibility, and short-term certainty that bridging finance delivers rather than cheapness.

The distinction between regulated and unregulated bridging is also relevant to cost. A regulated bridging loan is one secured on a property the borrower occupies or intends to occupy as their main residence; affordability checks and consumer credit rules apply. An unregulated bridging loan is secured on investment or commercial property — the product most property developers and professional investors use, covering houses, flats, HMOs, offices, retail units, industrial buildings, and hotels — and it typically carries different pricing dynamics and broader lender appetite across the specialist market.

Most bridging facilities are secured via a first charge over the subject property, which gives the lender the senior legal charge and priority on enforcement. Second charge bridging is also available where there is an existing mortgage on the security property, but second charge facilities carry tighter LTV limits and higher rates because the lender sits behind an existing charge-holder in the repayment waterfall.

Interest on bridging loans is quoted monthly, not annually, which can obscure the true annual equivalent cost. Market rates in 2025–2026 range from approximately 0.55% p.m. on prime, low-LTV deals with a clean funded exit, up to 1.5% p.m. or more for higher-risk cases. The bulk of mainstream commercial bridging transactions price between 0.65% and 0.99% p.m.

To translate monthly rates into annual equivalents: 0.75% p.m. compounded equates to approximately 9.4% p.a., while 1.0% p.m. compounds to around 12.7% p.a. These figures are substantially above standard commercial mortgage rates, reflecting the speed of capital deployment, the absence of long-term lender commitment, and the flexibility to exit early without penalty on most facilities.

Interest can be structured in three ways — retained, rolled-up, or serviced — each with different implications for cashflow, gross loan size, and the total interest charged. Understanding the difference is critical when comparing lender term sheets side by side.

When interest is retained, the gross loan amount — the figure the LTV is calculated against — includes the full interest stack for the agreed term. On a £500,000 net advance with nine months of interest retained at 0.75% p.m., the gross loan becomes £533,750, and loan-to-value is calculated against that higher figure. Always clarify whether a lender's stated LTV refers to the net or gross loan before accepting a term sheet.

Beyond monthly interest, a bridging facility carries several one-off fees. Some are unavoidable market-standard charges; others vary significantly between lenders or can be negotiated, particularly on larger loans. Mapping every charge before you sign ensures no surprises at completion.

The arrangement fee and exit fee interact significantly on total cost. A facility priced at 0.65% p.m. with a 2% arrangement fee and a 1% exit fee may cost more in aggregate than one at 0.75% p.m. with a 1% arrangement fee and no exit fee — particularly on a short three-to-six month term. Always model the all-in cost across your expected hold period rather than comparing headline monthly rates in isolation.

Broker fees deserve particular attention. A whole-of-market broker with access to 100+ lenders can often secure materially better rates and terms than approaching lenders directly, particularly on larger or more complex transactions. The cost of specialist intermediation is almost always offset by the saving achieved on the rate, arrangement fee, or both. Lenders routinely reserve their sharpest pricing for intermediary-sourced cases where due diligence has been completed before the deal reaches credit.

A bridging loan calculator is a simple but powerful tool for modelling the real cost of a facility before you approach a lender. Because bridging costs concentrate into three distinct buckets — interest, lender fees, and legal or professional fees — an accurate calculation needs to capture all three. A calculator that only returns monthly interest understates the true cost by 2 to 4 percentage points on most deals.

To model a bridging loan effectively, input the gross loan amount you require, the lender's monthly interest rate, and the expected term in months. Most calculators then allow you to select between retained, rolled-up, and serviced interest — each produces a different net advance and total cost figure. Add a realistic arrangement fee (typically 1.5% to 2% of the gross loan), a valuation fee appropriate to the property value, and budget figures for both sets of legal fees. Once these are included, the calculator shows you the net cash received at drawdown, the gross balance due at redemption, and the effective annualised cost of the facility.

For developers modelling a land acquisition or refurbishment deal, the calculator should also incorporate the post-drawdown costs that affect the exit — for example, the stamp duty payable on purchase, any professional fees associated with planning or architects, and the refinance costs on the exit product (whether a term mortgage, buy-to-let, or development facility). Treating the bridging cost in isolation produces a misleading picture of overall project profitability.

The single most useful modelling exercise is a sensitivity analysis on the term length. Model the loan at six, nine, and twelve months. If your realistic exit is nine months, retaining twelve months of interest adds three months of cost you will largely reclaim through an early-redemption refund, but it still creates a higher gross loan and therefore a higher LTV calculation. Conversely, retaining too few months risks a term extension and additional arrangement fees if the exit slips. The right answer is usually one or two months beyond your realistic exit date, negotiated with an extension option upfront.

Worked examples make the numbers concrete. The following illustration uses a typical commercial bridging scenario — a property investor purchasing an unmortgageable property at auction, intending to refurbish and then refinance onto a buy-to-let mortgage.

In this example, the all-in cost is approximately 9.5% of the gross loan amount over nine months. If the borrower redeems early at month six, unused retained interest is typically refunded, reducing the total cost to around £16,300. Early redemption provisions matter enormously: always confirm the lender's policy on refunding unused retained interest before drawdown, and ensure it is stated explicitly in the facility agreement.

For transactions with a sub-28-day completion deadline — such as an auction purchase — timing constraints add further complexity to structuring. Our guide to bridging loans for auction purchases covers how lenders approach compressed timescales and what documentation to have ready before the auction date.

Lenders price bridging loans individually based on the risk profile of each deal. There is no single published rate that applies universally — the rate you are offered reflects a lender's assessment of six core variables.

Loan-to-value (LTV) is the most important pricing factor. Lenders in the mainstream commercial bridging market will typically advance up to 75% LTV on a first charge against residential investment property, and 65–70% against commercial security. Lower LTV means less lender risk and a lower rate. Deals at 50% LTV or below attract the keenest rates available in the market.

Exit strategy quality is second only to LTV. A clean, funded exit — a sale agreed, or a refinance offer in principle from a term lender — commands a better rate than a speculative exit dependent on market conditions or planning being granted. Lenders scrutinise the credibility, timing, and fallback position of your exit before agreeing terms.

Property type and condition affect lender appetite and pricing. Prime residential property — houses and flats in major UK cities — is the easiest security class. Commercial property, mixed-use assets, development sites, HMOs, offices, hotels, retail units, and properties in poor condition all attract either higher rates or require specialist lenders from a broader panel. It is worth understanding whether a full development finance facility would be more appropriate than a bridging loan for transactions involving significant construction work, or whether refurbishment finance better suits a light refurbishment project.

Loan size influences pricing in both directions. Loans under £100,000 are often more expensive proportionately because the fixed costs of legal work and valuation weigh more heavily against the loan amount. Loans above £2M to £3M typically attract sharper rates because lenders compete aggressively for volume tickets.

Borrower credit profile and track record affect the market available to you. Bridging lenders are considerably more tolerant of adverse credit than conventional mortgage lenders — but significant county court judgements, undischarged defaults, or prior repossessions will narrow the pool of lenders and push rates higher. A demonstrated track record of successful exits, on the other hand, can open access to professional investor pricing.

Term length rounds out the key variables. A clearly defined, short term with a specific redemption date carries less risk than an open-ended facility. Most lenders offer terms of one to eighteen months; some specialist lenders extend to twenty-four months for the right transaction.

Preparing a strong, well-packaged application reduces the rate you are offered. Lenders price uncertainty into their rates; a deal presented with clear exit evidence, a credible business plan, professional valuations, and a demonstrated track record of completed transactions reduces perceived risk and directly improves the offer.

Structuring interest as serviced rather than retained eliminates the compounding effect and keeps the outstanding balance flat throughout the term, reducing total interest paid. This structure is only viable where monthly cashflow is available — but for investors with rental income or other liquid resources, modelling the saving is worthwhile.

Comparing all-in cost rather than headline rate is essential. A lender quoting 0.65% p.m. with a 2% arrangement fee, a 1% exit fee, and high legal panel costs may be more expensive overall than a lender at 0.80% p.m. with a 1% arrangement fee, no exit fee, and a fixed-fee legal panel. Always model the full cost across your expected hold period.

Using a specialist broker with a large lender panel delivers consistent savings. The difference between the best and worst bridging rates available for an equivalent deal can be 0.2–0.4% p.m. — on a £500,000 loan over nine months, that gap represents £9,000 to £18,000 in interest alone. Accessing the full market through a broker with 25+ years of experience and a panel of 100+ lenders consistently achieves better outcomes than approaching individual lenders directly.
