Properties that need real work often can’t be financed through a standard mortgage, since most residential lenders won’t lend against something that isn’t currently habitable or mortgageable. Refurbishment finance bridges that gap, funding the purchase and the works, with an exit onto a sale or a standard mortgage once the property is ready.
The right structure depends heavily on the scale of the work involved, which is why lenders draw a clear line between light and heavy refurbishment.
| Feature | Light Refurbishment | Heavy Refurbishment |
|---|---|---|
| Type of work | Cosmetic, such as a new kitchen or bathroom | Structural, extensions, or significant conversion work |
| Planning permission | Not usually required | Often required, depending on the scope |
| Typical LTV on purchase | Often up to around 75% | Often up to around 70% |
| Works funding | Sometimes funded upfront | Usually released in stages as work progresses |
The distinction matters because heavier projects carry more construction risk, which shapes both the rate a lender offers and how closely they monitor the works.
On heavier refurbishment projects, lenders typically release funds for the works in stages, similar to ground-up development finance, often based on either invoices for completed work or a surveyor’s inspection confirming progress. This protects against overfunding a project that stalls partway through, and it also means you’re not paying interest on funds you haven’t yet used.
We compare terms across a panel of specialist development finance lenders, including:
An investor found a two-bedroom flat needing a new kitchen, bathroom, and general decoration, priced well below similar properties nearby because of its condition. We arranged a light refurbishment bridging loan covering the purchase and the works, with the investor selling the finished flat within four months and repaying the loan from the sale.
A developer bought a large detached house intending to convert it into three flats, a heavier project requiring planning permission and structural work. We arranged heavy refurbishment finance with the works funding released in stages as the conversion progressed, and the developer’s exit plan was to refinance the completed flats onto buy-to-let mortgages rather than sell, building rental income into their portfolio.
Light refurbishment covers cosmetic work that doesn’t need planning permission or building regulations sign-off, such as a new kitchen or bathroom. Heavy refurbishment involves structural changes, extensions, or significant conversion work, usually requiring planning permission and closer lender monitoring.
Yes, this is exactly what refurbishment finance is designed for. Standard mortgages typically won’t lend on an unmortgageable property, which is why bridging-style finance exists to cover the gap until the property is habitable again. See our Bridging Loans page for more on how bridging finance works more broadly.
Lenders typically want a clear schedule of works with costs broken down, sometimes reviewed by a surveyor or quantity surveyor for larger projects. A realistic, well-documented budget makes the application process considerably smoother.
This is a common risk on any renovation project. Building a reasonable contingency into your budget from the outset, and flagging any overspend to your lender early, gives you the best chance of keeping the project on track without running out of funds partway through.
