Bridge First, Then Development Finance: When Bridging Comes First
Some sites have to be bought before a development facility can be put in place. This guide explains when a bridge comes first, how the bridge-to-development refinance works, and what to agree with the bridging lender at the outset.
When a bridge comes before development finance
A bridge comes first when you must buy a site faster than a development lender can commit: at auction, before planning is granted, or where the scheme is not yet ready for a build facility. The bridge secures the land, and once planning, costings and a contractor are in place you refinance onto development finance to fund the build.
If you are comparing the two products side by side, see our development finance vs bridging loans comparison. If you want the numbers, our cost worked example of the same scheme funded by a bridge and by development finance sets out the total cost of each. This guide covers the sequence where both are used: bridge for the purchase, development finance for the build.
Development finance is senior debt structured specifically for ground-up construction or heavy conversion projects. It covers land acquisition and build costs, with funds released in staged drawdowns as your project hits construction milestones verified by a monitoring surveyor.
Typical terms range from 12 to 24 months, with interest rates from 6.5% per annum. Lenders will fund up to 65-70% of the Gross Development Value (LTGDV), meaning you need equity or mezzanine to cover the rest.
Development finance is fundamentally a project loan. The lender underwrites your scheme - planning permission, build costs, contractor credentials, and exit strategy - not just the asset value today.
Expert Insight
Drawing on the £500M+ of property development finance our founder, Matt Lenzie, has arranged across his career, the bridge-first route works best when the refinance is planned on day one: agree early repayment terms with the bridging lender and have the development lender's criteria in mind before you bid.
What are bridging loans?
Bridging loans are short-term secured loans designed for speed. They bridge a gap between a purchase and a longer-term finance solution, or provide rapid capital for auction purchases, chain-breaks, or time-sensitive acquisitions.
Rates start from 0.55% per month (approximately 6.6% per annum), with terms from 1 to 18 months and LTV up to 75%. Unlike development finance, bridging loans are typically advanced as a single drawdown against the current value of the asset.
The key advantage is speed - funds can be available within 5-10 working days, compared to 4-8 weeks for a development facility.
Side-by-side comparison
Rates: Development finance from 6.5% p.a. vs bridging from 0.55% p.m. (6.6% p.a.). On the surface they look similar, but development finance interest is typically rolled up and only charged on drawn funds, while bridging interest accrues on the full advance from day one.
Loan-to-Value: Development finance offers up to 65-70% LTGDV (based on the completed project value). Bridging offers up to 75% LTV based on the current or purchase value of the asset.
Terms: Development finance runs 12-24 months to match the build programme. Bridging is shorter at 1-18 months. Both carry exit fees and potential extension charges if you overrun.
Drawdowns: Development finance uses staged drawdowns tied to build milestones. Bridging is a single day-one advance. This makes development finance more cost-efficient for projects with significant build periods.
Fees: Both typically carry 1-2% arrangement fees. Development finance adds monitoring surveyor costs (£500-£1,500 per inspection). Bridging may have exit fees of 1-1.5%.
| Feature | Development Finance | Bridging Loans |
|---|---|---|
| Purpose | Ground-up build & heavy conversion | Acquisition, chain-break, auction |
| Rate | From 6.5% p.a. | From 0.55% p.m. (6.6% p.a.) |
| LTV Basis | 65-70% of GDV | Up to 75% of current value |
| Term | 12-24 months | 1-18 months |
| Drawdown | Staged (milestone-based) | Single day-one advance |
| Speed | 4-8 weeks | 5-10 working days |
| Interest | Rolled up on drawn funds | On full advance from day one |
| Arrangement Fee | 1-2% | 1-2% |
When to use development finance
Choose development finance when you are undertaking a ground-up build, heavy structural conversion, or any project where the end value significantly exceeds the current site value. The staged drawdown structure means you only pay interest on capital as you need it.
Development finance is also the right choice when the project timeline exceeds 6 months, when you need to fund both land and build costs, or when you need to demonstrate to planning authorities or JV partners that you have an institutional-grade funding facility in place.
Typical projects: new-build residential schemes (3-100+ units), office-to-residential conversions, commercial developments, and mixed-use schemes.
When to use bridging loans
Bridging loans are the right tool when speed is the priority. Auction purchases with 28-day completion deadlines, securing a site before planning is granted, breaking a property chain, or acquiring a property that needs light refurbishment before refinancing onto a mortgage.
They also work well for short-term holds where you plan to sell within 6-12 months without significant works, or when you need to release equity from an existing asset quickly to fund a deposit elsewhere.
Do not use bridging for ground-up development - the single drawdown and shorter terms make it significantly more expensive than a proper development facility for projects over 6 months.
How the bridge-to-development refinance works
- Buy with a bridge. The bridging loan is advanced against the site's current value (typically up to 70% to 75% LTV), so completion can meet an auction deadline or beat other buyers to an unconsented site.
- Add value during the bridge term. Use the bridge period to secure or vary planning, discharge pre-commencement conditions, tender the build and appoint a contractor and professional team.
- Apply for development finance early. Development lenders typically need three to six weeks from application to first drawdown, so start the process well before the bridge term ends.
- Refinance on day one of the build. The development facility's first drawdown repays the bridge, and the remaining facility is released in stages as the build progresses.
Because the development lender values the site with planning in place, any uplift in value achieved during the bridge term can count towards your equity in the development facility. The bridge only has to cover the purchase, not the build; for how the two compare on total cost, see our worked cost example.
What to agree with the bridging lender at the outset
The bridge-first route gives you the speed of bridging with the cost efficiency of development finance for the build, provided the bridge is set up with the refinance in mind.
We arrange both facilities together, making sure the bridging lender's terms allow early repayment without penalty (or with minimum interest periods you can live with) when the development facility is ready to draw, and that the term leaves enough time for planning to be decided. Contact us to discuss your specific scenario.
For developers exploring other funding options, we also arrange mezzanine finance and refurbishment finance.

When comparing property finance options, consider the regulatory framework: the Financial Conduct Authority (FCA) regulates certain types of lending, while RICS standards govern valuations across all product types. HM Land Registry registration applies to all secured lending, and Building Regulations compliance affects the exit valuation regardless of which finance product you use.

Frequently asked
questions.
What is the main difference between development finance and bridging loans?
Development finance funds construction projects with staged drawdowns and is based on the completed value (LTGDV). Bridging loans provide a single lump sum quickly, based on the current asset value (LTV). Development finance is for building; bridging is for buying fast.
Which is cheaper, development finance or a bridging loan?
For construction projects over 6 months, development finance is almost always cheaper because you only pay interest on drawn funds. Bridging loans charge interest on the full advance from day one, making them more expensive for longer-term projects.
Can I use a bridging loan for a ground-up development?
It is not recommended. Bridging loans advance a single drawdown and have shorter terms (1-18 months). For ground-up builds you need staged drawdowns aligned to your build programme, which is what development finance provides.
How quickly can I get development finance compared to a bridging loan?
Bridging loans can complete in 5-10 working days. Development finance typically takes 4-8 weeks due to the need for detailed appraisals, monitoring surveyor appointment, and build cost verification.
