Light vs heavy refurbishment finance

Light refurbishment covers works that improve a property without changing its structure, such as new kitchens and bathrooms, decoration, flooring, rewiring and replacement windows. Heavy refurbishment covers structural work, such as removing load-bearing walls, extensions, loft conversions, new roofs, and changes of use that need planning permission.

The line between the two varies by lender. Many treat a project as heavy once it needs planning permission, building regulations approval for structural work, or a large share of the purchase price spent on works. A project can also move from light to heavy once problems are found during the work.

Light refurbishment finance is usually a short-term loan, often a form of bridging, that funds the purchase and the works on a property that needs updating before it can be let, sold or mortgaged. The works money may be paid upfront with the purchase or released after the valuer confirms parts of the work are done.

Because the structure is unchanged, lenders see light refurbishment as lower risk. The loan is usually repaid by selling the property or refinancing onto a mortgage once the works are finished.

Light refurbishment suits investors buying dated homes to let, and buyers whose home is habitable but not yet acceptable to a mortgage lender.

Heavy refurbishment finance funds structural work, conversions and changes of use, and sits close to development finance. Lenders usually release the works money in stages, after a monitoring surveyor confirms each stage is complete, and they look closely at the borrower's experience, the contractor and the planning and building control position.

Interest is often rolled up or retained in the loan, rather than paid monthly, because the property produces no income during the works. That makes the total cost depend on how long the project takes, so a realistic programme matters as much as the rate.

Projects that create new homes from scratch, rather than converting or extending existing buildings, are usually funded as development finance instead.

Lenders check the purchase price, the cost of works, the value once the works are finished and the exit, meaning how the loan will be repaid. A schedule of works with quotes, plans where needed and the borrower's track record all help. Heavier projects add a monitoring surveyor, building control sign-off and sometimes a structural engineer's report.

The exit is checked as carefully as the works. A plan to sell needs evidence of local demand, while a plan to refinance needs a mortgage that will be available on the finished property. How that refinance works for landlords is set out on the buy-to-refurb mortgages page.

Comparing refurbishment finance means looking at the rate, the arrangement and exit fees, how and when the works money is released, whether interest is retained, and the monitoring and valuation costs. A lower rate on a light refurbishment loan can still cost more than expected if the works take longer than planned.

Asking each lender for the same details, such as the maximum loan against the purchase price and the finished value, the release timetable and any conditions, makes the comparison fairer, and it shows which lender's terms fit the programme rather than the other way round. Pricing across refurbishment lending is set out on the refurbishment finance rates page.
