How Do Bridging Loans Work?

Right, let’s actually get into the mechanics here, because “it bridges a gap” is the one-line answer everyone gives, and it doesn’t tell you anything about what actually happens once you apply. Let me walk you through it properly, step by step.

Bank of England held base rate at 4.25% in June 2026 - waiting for inflation to cool.

73% of UK SMEs expect to grow in the next 12 months - confidence remains strong.

Step one: understand what you’re actually borrowing against

A bridging loan is secured against property, either the one you’re buying, one you already own, or both. Unlike a mortgage, the lender isn’t primarily interested in your monthly income, they’re interested in the property’s value and, crucially, exactly how you plan to repay the loan.

Step two: work out your exit strategy, before anything else

This is the single most important part of the whole process, more important than your credit score, more important than your income. Your exit strategy is simply your plan for repaying the loan, selling the property, refinancing onto a mortgage, or another confirmed source of funds arriving. Lenders will scrutinise this closely, and a vague or unconvincing exit strategy is the most common reason applications stall or get declined.

My top tip: if your exit is a property sale, get an estate agent valuation and evidence of demand before you apply, ideally a property already under offer or with exchanged contracts. If your exit is refinancing onto a mortgage, get that mortgage agreed in principle first. Both dramatically strengthen your application.

Step three: how much can you actually borrow?

Lenders cap lending as a percentage of the property’s value, the Loan-to-Value (LTV). Typical caps currently:

• Residential property, first charge: around 70-75%
• Commercial property: around 65-70%
• Second charge lending (where there’s already an existing mortgage on the property): around 65%

For heavy refurbishment projects, lenders often size the loan against roughly 70% of the property’s projected value once works are complete, rather than its current value.

Step four: understand how interest actually works

This is where bridging genuinely differs from a mortgage. Interest is quoted monthly, not annually, typically somewhere between 0.5% and 1.5% a month depending on your LTV, the property, and how strong your exit strategy is. You’ll usually choose between:

• Retained interest: the total expected interest is calculated upfront and deducted from the loan itself, so you make no monthly payments at all.
• Rolled-up interest: interest accumulates monthly and is added to the balance, repaid in full alongside the loan at the end.
• Serviced interest: you pay interest monthly, as you would with a standard mortgage, reducing what’s owed at the end.

Most bridging borrowers choose retained or rolled-up specifically because it means no monthly outgoings during the loan term, useful if you’re mid-renovation or waiting on a sale.

Step five: first charge or second charge?

If there’s no existing mortgage on the property, or the bridging lender takes primary legal priority, that’s a first charge loan, generally the cheaper option. If you already have a mortgage and the bridging lender sits behind it, that’s a second charge loan, priced higher to reflect the lender’s increased risk if things go wrong.

Step six: the actual application and completion process

• Initial application, covering the property, the loan amount, and your exit strategy
• Valuation, a surveyor assesses the property’s current value, and its projected value if refurbishment is involved
• Underwriting, the lender reviews your exit evidence, the property, and your circumstances
• Legal work, solicitors handle the charge registration and any other legal requirements
• Funds released, once everything is confirmed

For straightforward cases, this whole process can complete in as little as 5-14 working days, though more complex cases, unusual properties, adverse credit, complicated ownership structures, can take longer.

Step seven: what happens at the end of the term?

Bridging loans typically run from a few months up to around 18-24 months. Once your exit event happens, the sale completes, the refinance goes through, you repay the loan in full, principal plus whatever interest is owed depending on your chosen structure. If your exit is delayed, most lenders offer some flexibility to extend, though this usually comes at additional cost, which is exactly why a realistic, well-evidenced exit strategy matters so much from the outset.

What can a bridging loan actually be used for?

Genuinely broad, but common uses include:

• Buying a property before your current one has sold
• Purchasing at auction, where completion is required within 28 days
• Funding refurbishment before refinancing onto a standard mortgage
• Buying a property that isn’t currently mortgageable in its existing condition
• Raising quick capital against a property you already own

Who can actually get a bridging loan?

Individuals, partnerships, limited companies, SPVs, LLPs, and trusts can all apply, and for investment or commercial purposes, many lenders require no trading history or income verification at all, the loan is underwritten on the property and your exit strategy instead.

The bottom line

A bridging loan works by lending against a property’s value for a short period, typically a few months up to 18-24 months, with interest charged monthly and structured so you often don’t need to make ongoing payments during the term. What actually determines whether you’re approved, and at what rate, is your exit strategy far more than your income or credit history, get that evidenced properly before you apply, and the rest of the process moves considerably faster than most people expect.
