A specialist guide to commercial bridging loans

What a commercial bridge is

A commercial bridge is a short-term loan secured against commercial or investment property, used to fund a purchase or works quickly and repaid within months rather than years. It is the same instrument as a residential bridging loan, but the security and the borrower differ: the property is held for business or investment, the borrower is a company, investor or trading business, and the lending is unregulated commercial debt. A commercial bridging loan buys speed and flexibility that a mainstream commercial mortgage cannot, which is why investors and businesses reach for it when a deal will not wait.

This brand arranges bridging finance for one window in particular: the stabilisation window, from practical completion or a recent letting through the income ramp to a stabilised income that supports long-term debt. A bridge held across that window carries a finished but part-let asset until it earns the income a term lender needs to see. That specialism runs through everything below, and our core facility for it sits at /services/stabilisation-bridge-finance/.

How bridging finance works

Bridging finance works on a simple pattern. A lender advances funds secured by a first or second charge over the property, the borrower services the interest monthly or rolls it up, and the loan is repaid in full on an agreed exit within the term. Because the facility is short and exit-driven, the funder underwrites the asset and the exit more than the borrower's income, which is what makes a bridge fast to arrange.

1. Agree the loan against the property's value and a credible exit, with the term set to match it.
2. Draw the funds to complete the purchase, repay a maturing loan or fund the works.
3. Service the interest monthly, retain it from the advance, or roll it up to be settled at the end.
4. Repay the bridge in full from a refinance onto longer-term debt or from a sale.

What a commercial bridge funds

A commercial bridging loan funds the moments where speed or a gap in the funding chain would otherwise cost the deal. The common uses across investment property are these.

• Acquisition: completing a purchase faster than a commercial mortgage allows, then refinancing onto term debt once the asset is held.
• Auction: funding a lot inside the 28-day completion window, covered in our guide at /blog/auction-finance-explained/.
• Refurbishment: buying and improving a tired asset to lift its value and rent, set out at /blog/refurbishment-bridging-loans/.
• Development exit: repaying a development loan at completion while the scheme sells or lets, alongside the development route at /blog/development-loans-explained/.
• Lease-up carry: funding interest on a completed asset until it reaches a stabilised income, often as a bridge-to-let, explained at /blog/bridge-to-let-how-it-works/.

Each of these is a short-term loan with a defined job and a defined exit: on investment stock the bridge is usually the step before a longer refinance, and on a development the step after the build.

Bridging loan rates and fees

Bridging loan rates are quoted as a monthly percentage rather than an annual one, because the term is short. Indicatively, commercial bridging interest runs at around 0.95 percent a month, and the market commonly quotes rates between 0.55 and 1.25 percent a month depending on the asset, the leverage and the strength of the exit. On top of the interest sit an arrangement fee of around 1 to 2 percent, a valuation fee, legal costs for both sides, and sometimes an exit fee. Our full breakdown of what a bridge costs is at /blog/how-much-does-a-bridging-loan-cost/, and you can model a figure at /calculators/bridge-cost/. All figures here are indicative and illustrative, not an offer of credit.

The market that funds these loans is large and growing. The BDLA put the UK bridging and development loan book at a record 13.7 billion pounds as at Q3 2025, up 51.6 percent year on year, and recorded 11.7 billion pounds of applications in Q4 2025, which the BDLA frames as evidence of demand for short-term and exit finance.

Loan to value, criteria and exit strategy

Loan to value on a commercial bridge is commonly up to 70 to 75 percent of the property's value, lower on more specialist assets and higher where additional security is offered. The criteria that matter most are the quality of the asset, the credibility of the exit, and the borrower's experience with similar deals; a clean, contracted exit will often secure keener pricing than the headline rate suggests.

Every bridge needs a defined exit strategy, because the loan has to be repaid in full at the end of the term. The two routes are a refinance onto longer-term debt or a sale, with a short extension where an exit slips. Where the exit is a term loan, we line it up in advance through /services/bridge-to-term-finance/, so the bridge repays cleanly onto the follow-on facility. What happens as a bridge reaches its end is covered at /blog/what-happens-when-a-bridging-loan-ends/.

Regulated versus unregulated bridging

Whether a bridge is regulated depends on the security, not the label. Stabilisation Finance arranges commercial finance for businesses, investors and experienced borrowers, and this lending is unregulated. A bridge secured on a borrower's own home is a regulated mortgage contract overseen by the Financial Conduct Authority, and where a transaction would require FCA authorisation we refer it to a regulated firm. We are an arranger and introducer, not a lender.

This is also where charge order matters. A first-charge bridge sits ahead of other lending on the property; a second-charge bridge sits behind an existing loan to release equity without disturbing it, as set out at /blog/second-charge-bridging-loans/. Both can be unregulated on investment and commercial security.

How we arrange the facility

We arrange commercial bridging loans by matching the deal to the funder whose appetite fits it and structuring the facility around a credible exit. As an arranger and introducer we place each loan with a lender, size it against the asset and the exit, and line up the refinance or sale in advance so the funding plan runs through to repayment. We arrange this across the UK, and local market data sits at /locations/. Send us the property, the purpose and the numbers and we will come back with a view on likely terms.
