Quick answer
Refurbishment finance is short-term secured lending used to fund property improvement works — a specialised form of bridging loan with drawdown structures suited to the works. You typically use it to buy a property, renovate it, then exit by selling at the improved value or refinancing onto a normal buy-to-let or residential mortgage, over a term of 3–24 months. The single most important thing to understand is the light-versus-heavy classification, because it decides your rate, your maximum loan, how the money is released, and the paperwork required. Light refurbishment covers cosmetic, non-structural work (new kitchens and bathrooms, decorating, rewiring — nothing needing planning permission or building control): funded against the property’s current value up to ~75% LTV, often released in a single tranche, priced from around 0.65–0.85% a month. Heavy refurbishment covers structural work, extensions, and conversions (needing planning/building control): funded partly against the gross development value (GDV) — what it’ll be worth after works — typically up to 70% LTGDV, released in staged drawdowns verified by a monitoring surveyor, priced from around 0.85–1.25% a month. The classic mistake — and a common reason applications stall — is misclassifying a heavy project as light; the lender’s surveyor catches it and the deal restructures or collapses. As with all bridging, the exit strategy is everything (sale or refinance, evidenced not hoped), and the cost stack includes an arrangement fee (1–2%), valuation, monitoring and legals on top of interest. Get the classification and exit right and refurb finance is the tool that makes property projects possible; get them wrong and it’s an expensive false start. Position as of July 2026.
Your property may be repossessed if you do not keep up repayments or repay the loan.

What refurbishment finance is
At heart, refurbishment finance is a bridging loan shaped around a works project. Where a plain bridge simply funds a purchase, a refurb facility is underwritten with the works in mind — the lender assesses what you’re doing to the property, confirms which category it falls into, and structures the loan (and the way funds are released) to match. It usually covers both the purchase price and a proportion of the refurbishment costs, runs 3–24 months, and is interest-only with the interest typically rolled up and settled at exit. The users are familiar: investors buying below-market or unmortgageable properties to add value, landlords upgrading stock (including HMO conversions), and developers running BTL refurb-to-let projects — anyone whose plan is “buy it, improve it, then sell or refinance.” Because a property that’s uninhabitable or mid-works can’t get a normal mortgage, refurb finance is frequently the only way to fund the gap between a wreck and a mortgageable home — which is exactly the niche it exists to fill.
Light vs heavy: the classification that decides everything
Light refurbishment
Cosmetic, non-structural work — new kitchens and bathrooms, decorating, flooring, rewiring, replastering — nothing needing planning permission or building control. Funded against the property’s current value, typically up to 75% LTV, often released in a single tranche with no monitoring surveyor. Fast: 5–14 days to advance. Rates from ~0.65–0.85%/month. The straightforward end — a tired flat made rentable.
Heavy refurbishment
Structural work, extensions, conversions — anything needing planning permission or building control, changing the footprint, or converting use (office-to-resi, house-to-flats — often commercial conversions). Funded partly against gross development value (post-works value), typically up to 70% LTGDV, released in staged drawdowns verified by a monitoring surveyor. More documentation, more underwriting. Rates from ~0.85–1.25%/month. The involved end — a project, not a refresh.
The line between them isn’t about how much you spend — it’s about what the works are: structural or not, consented or not. That distinction sets your funding basis, your LTV, your drawdown method and your paperwork, which is why getting the classification right at the outset matters more than almost anything else in the application (the misclassification trap below is where projects most often stall). Some lenders add a “medium” refurbishment band for work that’s more than cosmetic but short of structural — useful middle ground a broker can place.
Why heavy refurb uses GDV — and what that means for you
The single concept that trips people up: light refurb lends against what the property is worth today; heavy refurb lends partly against what it’ll be worth after the works — the gross development value (GDV). That’s genuinely useful, because it lets a project fund works that today’s value alone wouldn’t support — a lender advancing against a £400,000 post-works GDV can lend more than one capped at the £250,000 current value. The trade-offs: because the lender is betting on a future value, they underwrite harder — a detailed schedule of works, a monitoring surveyor checking progress before each drawdown is released, and evidence you (or your contractor) can deliver. Funds arrive in tranches tied to construction milestones, not all upfront, so you need working capital or a structure that funds each stage. And note the net vs gross point common to all bridging: with interest rolled up, the day-one cash you receive (net) is below the headline facility (gross), so confirm the net advance actually covers your purchase and early works. It’s more machinery than light refurb — but it’s the machinery that makes ambitious projects fundable.

Rates, fees and a worked example
Like all bridging, refurb finance is priced per month: roughly 0.65–0.85% for light and 0.85–1.25% for heavy in 2026, with the sharpest pricing for low-LTV, experienced borrowers with strong evidenced exits. Beyond interest, the cost stack: an arrangement fee of 1–2%, a valuation (higher for GDV assessments), monitoring surveyor fees on heavy projects (per drawdown), legals for both sides, and often a broker fee and possible exit fee.
| Project | Facility & rate | Term | Interest cost |
|---|---|---|---|
| Light — flat refresh | £180,000 @ 0.75%/mo | 6 months (rolled) | £8,100 |
| Heavy — extension & reconfigure | £300,000 @ 1.0%/mo | 12 months (rolled, staged) | £36,000 |
The number that actually matters isn’t the rate — it’s the project ROI after all finance costs. A light refurb adding £40,000 of value for £8,100 of interest plus ~£5,000 of fees clears a healthy margin; a heavy project only works if the post-works GDV comfortably exceeds purchase-plus-works-plus-finance. Run the whole sum, honestly, before committing — the cost of the money is only worth it if the value uplift beats it, and optimistic works budgets are where refurb projects most often disappoint.
The exit: sell or refinance
As with every bridge, the exit strategy is the basis of the loan, and refurb finance has two classic exits. Sell — flip the improved property at its new value and repay from the proceeds (the “buy, renovate, sell” model); lenders want to see the numbers stack at a realistic sale price, not a hopeful one. Refinance — the “buy, refurbish, refinance” (BRR) model beloved of landlords: once the property is renovated and mortgageable, remortgage onto a normal BTL or residential mortgage at the improved value, repay the bridge, and often pull much of your original capital back out to recycle into the next project. The refinance exit is what makes refurb finance a portfolio-building engine rather than a one-off — but it depends on the finished property valuing where you expect and a mortgage lender accepting it, so an evidenced exit (a decision in principle on the take-out mortgage, a realistic post-works valuation) prices the bridge cheaper and de-risks the whole project. A vague exit — “I’ll sell it, probably” — prices as the risk it is, or gets declined.
Getting it: criteria, process and the misclassification trap
Criteria centre on the project and the exit: a credible evidenced exit (sale or refinance), a detailed schedule of works and costings, LTV within the lender’s cap (75% current-value for light, 70% LTGDV for heavy), and your experience — seasoned refurbishers attract better rates and higher LTVs, while first-timers (including the self-employed and company borrowers) can still borrow at a premium with a solid team. Adverse credit is assessed as with bridging generally: it affects pricing more than eligibility, since these loans are asset-led. New SPVs and companies are routine, with directors’ personal guarantees standard. Process: terms in principle in a day or two, valuation (current value for light, GDV for heavy), legals, then completion — light cases in 5–14 days, heavy a little longer for the extra underwriting.
The misclassification trap — the #1 reason refurb applications stall
Presenting a heavy project as light refurbishment is one of the most common ways an application derails. Borrowers underestimate their scope — assuming a loft conversion or a knocked-through wall is “cosmetic” — apply on a light-refurb basis, and then the lender’s surveyor reviews the schedule of works, spots the structural or consented element, and the deal restructures onto heavy terms (different rate, LTV and drawdown) or collapses, wasting the valuation fee and weeks of time. The fix is simple: be honest and precise about the works up front, and let a specialist broker classify the project before an application goes in. Getting it right first time is faster and cheaper than being caught out.
The bottom line
Refurbishment finance is bridging built for works: short-term funding to buy, renovate and then sell or refinance, over 3–24 months. Everything flows from one classification — light (cosmetic, current-value, single tranche, ~0.65–0.85%/month) versus heavy (structural, GDV-based, staged drawdowns with a monitoring surveyor, ~0.85–1.25%/month) — and the commonest failure is misclassifying heavy as light. Nail the classification, evidence a real exit (sale or BTL refinance), and run the ROI after all finance costs, and it’s the tool that turns unmortgageable wrecks into profit or rental income. It’s specialist, broker-led, and unforgiving of optimistic budgets — so price it honestly and take advice.

Refurbishment finance: FAQs
What is refurbishment finance?
Short-term secured lending to fund property improvement works — a specialised form of bridging loan structured around the works. You typically use it to buy a property, renovate it, then exit by selling at the improved value or refinancing onto a normal buy-to-let or residential mortgage, over a term of 3–24 months. It usually covers both the purchase price and a proportion of the refurbishment costs, is interest-only with interest often rolled up to the end, and is the standard way to fund properties that are currently unmortgageable because they need work before a normal lender will touch them.
What’s the difference between light and heavy refurbishment finance?
The classification decides everything. Light refurbishment covers cosmetic, non-structural work needing no planning permission or building control (kitchens, bathrooms, decorating, rewiring) — funded against current value up to around 75% LTV, often in a single tranche with no monitoring surveyor, from about 0.65–0.85% a month. Heavy refurbishment covers structural work, extensions and conversions needing consents — funded partly against gross development value up to around 70% LTGDV, released in staged drawdowns verified by a monitoring surveyor, from about 0.85–1.25% a month. It’s about what the works are, not how much you spend.
How much does refurbishment finance cost?
Interest runs roughly 0.65–0.85% per month for light refurbishment and 0.85–1.25% for heavy in 2026, with sharpest pricing for low-LTV, experienced borrowers with strong exits. On top sits the cost stack: an arrangement fee of 1–2%, valuation (higher for GDV assessments), monitoring surveyor fees on heavy projects, legal costs for both sides, and often a broker fee and possible exit fee. The figure that matters most is your project ROI after all finance costs — a light refurb adding £40,000 for around £13,000 of total finance cost clears a margin; a heavy project only works if the post-works value comfortably beats purchase plus works plus finance.
What is GDV in refurbishment finance?
GDV is gross development value — what the property will be worth once the works are complete. Light refurbishment lends against current value, but heavy refurbishment lends partly against GDV, typically up to 70% loan-to-GDV, which lets a project fund works that today’s value alone wouldn’t support. The trade-off is harder underwriting: because the lender is betting on a future value, they require a detailed schedule of works, a monitoring surveyor checking progress before releasing each staged drawdown, and evidence you can deliver. Funds arrive in tranches tied to milestones rather than all upfront.
Can I use refurbishment finance to buy, refurbish and refinance (BRR)?
Yes — that’s one of its two classic exits, and the model landlords use to build portfolios. You buy a property (often below market or unmortgageable), refurbish it with the finance, then once it’s renovated and mortgageable you remortgage onto a normal buy-to-let or residential mortgage at the improved value, repay the bridge, and often pull much of your original capital back out to recycle into the next project. It depends on the finished property valuing where you expect and a mortgage lender accepting it, so an evidenced exit — a decision in principle on the take-out mortgage and a realistic post-works valuation — both prices the bridge cheaper and de-risks the project.
Why do refurbishment finance applications get declined?
The most common reason is misclassifying a heavy project as light: borrowers underestimate their scope, apply on light-refurb terms, and the lender’s surveyor spots the structural or consented work, forcing a restructure onto heavy terms or collapsing the deal and wasting fees and time. Other reasons mirror bridging generally: a vague or unrealistic exit strategy, an over-optimistic works budget or post-works valuation, insufficient borrower experience for the project’s complexity, or an LTV beyond the lender’s cap. The fix is honesty and precision up front — let a specialist broker classify the project and evidence the exit before an application goes in.
