Why developers use bridging loans
Property development projects often involve properties that are outside the criteria of standard mortgage lenders. A derelict house, a former commercial building earmarked for residential conversion, or a structurally compromised property that needs significant renovation — these are all situations where conventional finance is unavailable or impractical. Bridging loans fill this gap by providing short-term funding secured against the property, allowing developers to purchase, renovate, and then either sell or refinance.
Speed is another critical factor. Development opportunities are competitive, and the ability to move quickly can be the difference between securing a deal and losing it. A bridging loan can complete in days or weeks, whereas development finance from traditional sources often takes considerably longer to arrange.
Bridging vs development finance
It is important to understand the distinction between a bridging loan and a dedicated development finance facility. A bridging loan provides a lump sum secured against the property, typically up to 75% of the current value. It is most suitable for light-to-medium refurbishment projects where the development costs are relatively modest and the borrower can fund the works from other sources or from a proportion of the loan advance.
Development finance, by contrast, is a more structured product designed for larger projects. It typically provides funding in stages (known as drawdowns) as the development progresses, with each stage released after an inspection confirms the previous phase is complete. Development finance also usually lends against the gross development value (GDV) rather than just the current value, potentially providing higher levels of funding.
For many small-to-medium property developers, bridging loans are the preferred option because they are simpler to arrange, faster to complete, and involve less ongoing administration than staged development finance. The choice between the two depends on the scale and complexity of the project.
Types of development projects suited to bridging
Light refurbishment
Light refurbishment involves cosmetic and non-structural work: new kitchens and bathrooms, redecoration, new flooring, garden landscaping, and similar improvements. These projects typically cost less than 15% of the property value and can be completed within a few months. Bridging loans are ideal for light refurbishment because the work does not fundamentally change the property and the risk to the lender is minimal.
Heavy refurbishment
Heavy refurbishment involves structural work: removing or adding walls, re-roofing, underpinning, installing new plumbing and electrical systems, or extending the property. These projects are more complex, take longer, and cost more. Bridging lenders will typically require a detailed schedule of works and may retain a portion of the loan funds to be released in stages as the work progresses.
Conversion projects
Converting commercial property to residential use — particularly under permitted development rights — has become a popular development strategy. Bridging loans fund the purchase and conversion of offices, retail units, and other commercial buildings into flats or houses. These projects typically require planning permission or a permitted development certificate, and the bridging lender will want to see evidence that the necessary consents are in place.
Development exit finance
Development exit bridging is used at the end of a larger development project when the main development finance facility is due for repayment but units have not yet been sold. Instead of extending the development loan at potentially unfavourable terms, the developer takes a bridging loan to repay the development finance and then sells the remaining units at their own pace. This can save significant costs if the development finance was at a high rate.
How lenders assess development bridging applications
For development bridging, lenders assess the current value of the property, the proposed works, the estimated end value after completion, and the credibility of the developer's plan. Experience matters — first-time developers may face more questions and potentially higher rates than experienced professionals with a track record of successful projects.
The exit strategy is critical. If the plan is to sell the completed property, the lender will scrutinise the projected sale price against comparable evidence. If the plan is to refinance onto a buy-to-let mortgage, the lender will want to know that the property will meet the criteria of mainstream mortgage lenders after the works are complete.
Lenders also consider the development timeline. If you say the refurbishment will take three months, the lender will want to see a realistic schedule of works that supports this timeframe. Overly optimistic timelines are a red flag that can lead to application decline or, worse, a completed project that runs over schedule and incurs additional bridging costs.
Costs for development bridging
Development bridging loan rates are similar to standard bridging rates, typically ranging from 0.5% to 1.2% per month depending on the LTV, the complexity of the project, and the borrower's experience. Arrangement fees of 1% to 2% of the loan amount apply, along with valuation fees (which may be higher for development projects requiring a dual valuation of current and projected end value) and legal costs.
For a typical refurbishment project — purchasing a property for £200,000, borrowing £150,000 on a bridging loan at 0.7% per month for eight months — the interest cost would be £8,400, plus an arrangement fee of £2,250 (1.5%), valuation of £800, and legal costs of £2,000, totalling approximately £13,450.
Funding the development works
A key consideration is how the actual renovation works will be funded. The bridging loan covers the property purchase, but the development costs need separate funding. Some developers fund works from their own cash reserves. Others negotiate with the bridging lender to include a works fund within the bridging loan, though this is more common with heavy refurbishment bridging and may require staged drawdowns.
For larger projects, combining a bridging loan for the purchase with a separate development finance facility for the works can be efficient, though this adds complexity. Your broker can advise on the most cost-effective funding structure for your specific project.
Finding the right development bridging lender
Not all bridging lenders are comfortable with development projects. Some specialise exclusively in light refurbishment, while others have dedicated development bridging teams with expertise in heavy refurbishment and conversion projects. Choosing the right lender for your specific project type is important, and this is where a specialist broker adds significant value.
Nesto matches you with bridging loan brokers who have specific experience in property development finance. They understand development timelines, can structure the funding to suit your project, and know which lenders are most competitive for your type of scheme. The matching service is free.
