Bridging Finance for Commercial to Residential Conversions
Last updated: November 2025
Converting Commercial Spaces into New Homes
Converting offices or commercial buildings into homes is one of the most profitable and in-demand property strategies in the UK. But with complex titles, tight timelines, and changing planning rules, success depends on having the right finance partner from the start.
With the right planning permission or permitted development rights, these projects can turn underused buildings into attractive, high-yield homes. The key to making it work is access to fast, flexible funding. That is where bridging finance for conversions comes in.
What Is Bridging Finance for Conversions
Bridging finance for conversions provides short-term funding to help you buy and convert a property that would not qualify for a standard mortgage. It gives you time to complete works, secure tenants, or sell on, before refinancing or exiting through sale.
Traditional mortgages rarely fund conversion projects because the property is often unmortgageable in its current state. Bridging finance fills that gap, giving developers the speed and flexibility to unlock a site’s potential.
At GPS Financial, we arrange bespoke conversion finance for investors, developers, and landlords across the UK. With over a decade of experience, our team structures each facility around the project, ensuring the funds are released on time and the exit plan is achievable.
When to Use Conversion Bridging Finance
• Purchasing an office building or retail unit for residential conversion
• Buying a property with a short lease or vacant possession
• Converting a mixed-use building into self-contained flats
• Reconfiguring layouts under permitted development rights
• Releasing equity from another property to fund build costs
Key Features and Benefits
• Funding typically from six to eighteen months
• Loans from £100,000 up to £25 million
• Up to 75% of the property value, or higher with additional security
• Funds released in stages as work progresses
• Interest can be rolled up or retained to protect cash flow
• Available for individuals, companies, or SPVs
• Flexible terms designed around your exit plan
Step-by-Step Process
1. Decision in principle
We secure a same-day decision in principle to confirm borrowing potential and outline the structure of your facility.
2. Valuation and legal work
Once the purchase is agreed, valuation and legal checks begin immediately. We work closely with experienced solicitors who understand how to move quickly on commercial conversions.
3. Funds released
After approval, funds are released to your solicitor, allowing you to complete on the property and start works right away. Our team manages communication between lender, valuer, and solicitor, keeping progress on track so you can focus on the build rather than chasing paperwork.
4. Exit strategy
When the conversion is complete, you refinance onto a long-term buy-to-let or commercial mortgage, or sell to release profit.
Real Example: Office Conversion in Reading
A developer approached us to fund the conversion of a two-storey office building in Reading into eight modern apartments.
We arranged £1.8 million in bridging finance, covering both the purchase and 100 percent of the build costs. Drawdowns were managed through a monitoring surveyor, and the project completed within ten months.
Once finished, the client refinanced onto a long-term buy-to-let mortgage, achieving strong rental yields and releasing equity for their next purchase.
Outcome: completed on time, within budget, and refinanced smoothly into a profitable long-term portfolio asset.
Costs and Considerations
Rates typically start from around eight percent per year, depending on the loan size, property type, and borrower experience. Every conversion loan is bespoke, with fees, valuation, and legal costs confirmed in advance.
Every conversion is unique; that is why GPS Financial works with a wide panel of specialist lenders to match each project to the most suitable structure and terms.
We always begin with a clear exit plan to ensure the numbers work in practice, not just on paper.
