Bridging finance is fast, short-term, property-secured funding — for buying at auction, breaking a chain, refurbishing, or moving quickly before longer-term finance is in place. Use the calculator to estimate your monthly cost, then source the lenders who can move at speed.

Products are uploaded directly by lenders, so you're sourcing live, current bridging deals. Once you've run your figures, shortlist what fits and apply online. Your application is then handled by Dynamic Commercial Finance, our specialist brokerage team, who fact-find your case and submit it to the lender.

What is a bridging loan?

A bridging loan is short-term finance secured against property, usually running a few months up to 18–24 months. It's designed to "bridge" a gap — completing a purchase before a sale or refinance goes through — and is priced monthly rather than annually because of its short life.

Common uses: auction purchases (28-day completion), chain breaks, refurbishment (light or heavy), buying before selling, releasing capital quickly, and pre-planning site acquisition.

Key features

First or second charge

A first charge is the lowest-risk, cheapest position; a second charge sits behind an existing mortgage and prices higher.

Interest structure

Rolled-up (accrues and repaid at the end), retained (deducted from the advance upfront), or serviced (paid monthly). Rolled-up is the most common for investors.

Exit strategy

How you'll repay (sale or refinance) is central to pricing and approval.

How the calculator works

Enter the loan amount, property value (for LTV), the monthly rate and the term, and the calculator estimates your monthly interest and total cost. Model rolled-up versus serviced interest to see the difference in cash flow and total cost.

The result is a guide, not a formal quote. Your rate depends on LTV, security, exit and experience — the live products you source reflect what lenders will actually offer.

Bridging loan rates in 2026

With the base rate at 3.75%, UK bridging loans in 2026 are typically priced in three bands (monthly rates):

  • Prime (≈0.55%–0.75%/month) — sub-65% LTV, prime residential security, clean credit, a confirmed exit.
  • Standard (≈0.75%–0.95%/month) — standard residential or light commercial, 65–75% LTV, good credit, clear exit.
  • Complex (≈0.95%–1.5%/month) — adverse credit, non-standard security, high LTV, development land or second charge.

A rate of 0.75% per month is roughly 9% annualised on a simple basis (higher if rolled up and compounding). The single biggest lever on your rate is LTV — lowering it and evidencing a solid exit is what secures sharp pricing. Loans typically range from around £50,000 to £25 million+, and beyond the rate you'll usually have arrangement fees plus valuation and legal costs.

Regulated vs unregulated: most investment and commercial bridging is unregulated; a bridge secured on your own home can be regulated. Dynamic Commercial Finance will place regulated cases appropriately.

Bridging loan FAQs

Common questions about interest structures, speed, exits and regulation.

How is bridging interest charged?

Monthly, not annually. It can be rolled up (repaid at the end), retained (deducted upfront) or serviced (paid monthly). Rolled-up is most common for investors.

What happens after I apply?

Your application goes to Dynamic Commercial Finance, our specialist brokerage team, who fact-find your case and submit it to the lender.

How fast can a bridging loan complete?

Bridging is built for speed — straightforward cases can complete in days to a couple of weeks, which is why it's used for auctions and chain breaks.

What is an exit strategy?

How you'll repay the loan — usually the sale of a property or refinancing onto longer-term finance. A clear, evidenced exit is central to approval and pricing.

Are bridging loans regulated?

Most investment and commercial bridging is unregulated. A bridge secured on your own home can be regulated — we'll place those cases appropriately.

Bridging blogs

A bridging loan is secured against property, which may be repossessed if you do not repay. Most investment and commercial bridging is not regulated by the Financial Conduct Authority. Bridging is short-term finance and should not be used for long-term borrowing.
