Bridging Loans: When and How to Use Short-Term Finance

The Power of Unregulated Bridging for LTDs:
Because corporate borrowing is unregulated, lenders can underwrite loans on asset value, developer track record, and exit credibility rather than rigid consumer income checklists. Approvals can be granted within hours.
In This Guide:
1. What is a Commercial Bridging Loan?
A bridging loan is a short-term property-secured debt facility lasting typically between 1 and 24 months. Designed as a temporary bridge to a long-term funding arrangement or asset disposal, bridging finance prioritises speed of drawdown and situational flexibility over low long-term borrowing costs.
2. When to Use Bridging: Auctions, Chain Breaks & Refurbishment
Commercial bridging loans serve several indispensable corporate functions:
Auction Purchases
Auction contracts require unconditional legal completion within 28 days. High street banks cannot meet this timeline; bridging lenders regularly complete in 10 to 14 days.
Unmortgageable Properties
Dilapidated properties lacking kitchens, bathrooms, or structural integrity fail standard mortgage criteria. Bridging funds the purchase and refurbishment works.
Property Chain Breaks
Allows a company to secure a new commercial freehold immediately before the sale of their existing premises has legally exchanged.
3. Interest Options: Retained, Rolled-Up & Serviced
Borrowers can select how interest is handled across the term:
- Retained Interest: The total anticipated interest for the facility term is calculated upfront and deducted from the gross advance on day one. Borrowers pay zero monthly payments. If repaid early, unutilised interest is rebated.
- Rolled-Up (Accrued) Interest: Interest compounds monthly against the loan balance and is repaid in a single bullet payment upon redemption.
- Monthly Serviced: The borrower pays interest on a monthly standing order, exactly like an interest-only mortgage. Requires documented proof of monthly cash flow. Model retained vs rolled-up interest and net advances with our interactive Commercial Bridging Loan Calculator, or test term debt options via our Commercial Mortgage Calculator.
4. Securing a Bulletproof Exit Strategy
No bridging lender will advance capital without an explicit, verifiable exit strategy:
- Exit 1: Term Refinance: Securing a long-term commercial mortgage or SPV buy-to-let mortgage once works are completed and commercial tenants or residential ASTs are in place.
- Exit 2: Open Market Sale: Selling the upgraded asset on the commercial open market to redeem the loan balance.
5. Costs, Rates & Facility Fees in 2026
Current typical market benchmarks across the UK specialist lending panel:
- Monthly Interest Rate: 0.60% to 0.85% per month (7.2% to 10.5% annual equivalent) for residential investment and mixed-use; 0.70% to 0.95% for pure commercial assets.
- Lender Arrangement Fee: 1% to 2% of the gross loan facility, typically deducted from the net loan advance.
- Exit Fee: Frequently 0% with prime specialist lenders, though some charge 1% upon facility redemption.
- Heavy Refurbishment & Class MA Conversions: Up to 70-75% Loan-to-Value (LTV) on day-one acquisition, with 100% of construction and conversion works funded in arrears up to 70% of completed GDV (as verified by RICS valuations; see our Valuations Guide).
6. Frequently Asked Questions
How fast can a commercial bridging loan complete?
Commercial bridging loans can complete in as little as 5 to 10 working days, provided the valuation and title searches are expedited. This makes bridging finance the gold standard for property auction purchases.
What is an exit strategy and why is it mandatory?
An exit strategy is the clearly documented method by which the bridging loan will be repaid in full at the end of the term (typically within 6 to 18 months). Common exits include property sale or refinancing onto a long-term commercial mortgage.
Can bridging loan interest be rolled up?
Yes. Most commercial bridging lenders allow interest to be retained or rolled up into the loan facility, meaning the borrower makes zero monthly payments during the loan term.
