Refurbishment Finance: Light vs Heavy, Costs and Metrics

What Refurbishment Finance Actually Is

You use refurbishment finance to fund the renovation, conversion or improvement of a building that already stands, rather than one built from scratch. It sits between a standard bridging loan and full ground-up development finance, and it covers a wide stretch of ground: a rewire and a new kitchen at one end, an office-to-flats conversion at the other.

Where your project sits on that stretch decides the facility, the rate and how quickly the money reaches you, which is why the light-versus-heavy split is worth settling before you approach a lender rather than after. Get it wrong and you find out late, when you file for a consent you had assumed you would not need. The building itself is what keeps the pricing kinder than ground-up: a tired terrace already secures more of your loan on day one than a cleared plot ever will.

Light vs Heavy Refurbishment

You’re doing light refurbishment when the work is cosmetic: redecoration, a new kitchen or bathroom, flooring, minor repairs, with no structural change and no planning permission. Lenders treat that as bridging, and you usually fund the works from your own cash flow.

Your project turns heavy the moment you touch structure, change of use, a conversion, or an extension that needs planning. That’s the real dividing line, and it isn’t a question of budget: a £40,000 cosmetic refit stays light, while a much smaller job that moves a load-bearing wall does not. Heavy work needs a monitored drawdown facility much closer to development finance, released in tranches against a surveyor’s certificate rather than handed over at the start.

So the architect who confirms your office-to-flats conversion needs consent has just moved the deal from a bridge to a monitored facility, whether or not anybody says so at the time. The lender will re-price it, and the works will now be paid for in stages.

How Refurbishment Finance Works

You take an initial advance that covers the purchase price, or redeems an existing mortgage, plus mobilisation costs, and then draw the build down in stages. Each drawdown is released only after a monitoring surveyor certifies the works are actually in place, so it’s the surveyor’s visit, not the builder’s invoice, that stands between the work and the money.

At 65 to 75% of current value on purchase, and up to 75 to 80% of total cost on heavy schemes, the day-one loan looks generous. The cap that binds in practice is the one on end value: most lenders limit exposure to 65 to 70% of what the finished building is worth, and the lower of the two sums is your loan. A scheme with a thin uplift hits that ceiling long before it reaches the cost limit.

You exit by selling the finished units or refinancing onto a long-term mortgage, and both take longer than the works do. Build the gap between the last drawdown and the first sale into the term you ask for at the outset, rather than into an extension you have to ask for at month-end.

What Refurbishment Finance Costs

You’ll usually pay less than on ground-up development, because the standing building is stronger security. Light refurbishment bridging runs around 0.6 to 1% a month; heavy refurbishment sits between bridging and development pricing, roughly 0.75 to 1.3% a month.

The catch on a small refurbishment is that your fees don’t shrink with the loan. An arrangement fee of 1 to 1.5% sits on top of the rate, along with the monitoring surveyor’s costs and legal fees for both sides, and those last two barely move with the size of the facility. The smaller your scheme, the more of your margin they take.

Rolled-up interest is the line you need to watch, because it does two things at once. It keeps the monthly payment off your cash flow while the works run, and it quietly grows the balance you have to clear at the end. Add it to the fees before you decide whether the finished scheme is worth building, not once the builders are on site.

Who Refurbishment Finance Suits

Refurbishment finance fits you best if you’re a property investor upgrading buy-to-let stock before refinancing onto a long-term mortgage, or a developer converting commercial property to residential, often under permitted development rights. The other classic case is buying to add value: distressed or unmortgageable stock bought to refurbish and sell, or a house extended or converted into a House in Multiple Occupation (HMO).

All of them need an uplift big enough to clear your borrowing with room left over. The finished value has to cover the loan, the interest that’s rolled up on it and every fee, and still leave a margin worth a year of your time. Run that sum before you buy rather than when you pay the first invoice, because if it only just clears, you’re doing the job for the lender.

Skip it if the money wouldn’t make the building worth more. Stock that’s already lettable and already mortgageable is a job for a term loan or a remortgage, not for a monitored facility with a surveyor attached to it.
