What does a refurbishment bridging loan fund?
A refurbishment bridge can fund a property acquisition, release money against an existing property or include a facility for agreed works. The permitted purpose and release of funds depend on the product. Buying a property that needs renovation does not automatically mean the purchase loan also pays the building bills.
Distinguish cosmetic repairs from structural work, extensions and changes of use. Lenders define light and heavy refurbishment differently, so provide a detailed schedule rather than relying on those labels. Obtain the necessary planning, building-control and other consents for the actual project before assuming the timetable is achievable.
Current value and GDV are different lending measures
The legal security is the property. Gross development value (GDV) is an estimate of its value after the specified works; it is not cash available on the purchase date and is not a universal basis for every refurbishment loan.
Read the offer for each applicable limit:
| Measure | What to establish |
|---|---|
| Day-one loan-to-value (LTV) | Initial lending against the lender's stated current-value or purchase-price basis |
| Loan-to-cost (LTC) | Which acquisition and works costs count, and how much of them may be financed |
| Loan-to-GDV (LTGDV) | Total borrowing permitted against the supported completed valuation |
| Interest and fee allowance | Whether these fit inside the quoted limit or require additional headroom |
For a concrete product example, LendInvest's September 2026 Refurb GDV guidance distinguishes day-one LTV from completed-value lending and describes works drawdowns paid in arrears. Those are that lender's product arrangements, not market-wide rules.
There is also no single 24-month maximum for everything marketed as refurbishment bridging. Term, leverage, interest method and eligible works are contractual. Shawbrook's bridging page provides an example of a lender offering both a stated term limit and an option for upfront light-refurbishment funding. Compare the actual offers rather than combining the most generous features of different products.
Build a cash schedule before agreeing to staged funding
Prepare a dated schedule showing the purchase, works invoices, loan releases, interest and exit. If works funds are released after inspection, cash may be needed to pay the contractor before the lender reimburses eligible spending. Confirm the inspection process, release conditions, fees and treatment of cost overruns.
Separate VAT-inclusive costs, contingency, professional fees and any costs the lender will not fund. An undrawn works facility cannot pay a completion bill unless the lender permits that drawdown at the required time. Keep a reserve that remains accessible if a stage is delayed.
Worked example: acquisition loan plus a later works drawdown
The following assumptions are illustrative, not a quote or a lender's standard terms. Use a £150,000 purchase, £25,000 works budget and projected £190,000 completed value. Assume £112,500 of principal is advanced at completion and £25,000 at the start of month four. The second advance is assumed to follow reimbursement of eligible works initially paid by the borrower.
Assume 1% monthly simple interest, rolled up for six full months on the first draw and three full months on the second. Fees are 2% arrangement and 1% exit, both on the total £137,500 principal. The arrangement fee is paid from the borrower's cash. The contractual facility must separately allow the accrued interest; confirm that headroom with the lender.
| Calculation | Amount |
|---|---|
| Initial advance interest: £112,500 × 1% × 6 | £6,750 |
| Works advance interest: £25,000 × 1% × 3 | £750 |
| Total interest | £7,500 |
| Arrangement fee: £137,500 × 2% | £2,750 |
| Exit fee: £137,500 × 1% | £1,375 |
| Total finance cost before other charges | £11,625 |
| Redemption: £137,500 principal + £7,500 interest + £1,375 exit fee | £146,375 |
The purchase contribution is £37,500 before tax and transaction fees. If the full £25,000 works cost must be paid before reimbursement, the borrower temporarily needs £65,250 for purchase equity, works and the £2,750 arrangement fee, before other costs and reserves. Later reimbursement reduces the cash tied up but does not remove that earlier funding requirement.
Charging six months' interest on the full £137,500 would overstate this particular staged-interest example; charging only on £112,500 would understate it. Actual contracts can include minimum interest, compounding or different charging rules. The bridging cost calculator helps screen a facility, but reconcile staged releases with the lender's drawdown schedule rather than treating all funds as available from day one.
A valuation uplift does not guarantee a complete refinance exit
At the example's £190,000 completed value, a hypothetical 75% mortgage would be £142,500. That leaves £3,875 to repay the £146,375 bridge redemption, before refinance fees. At a £180,000 valuation, the same assumed LTV produces £135,000 and the shortfall becomes £11,375.
Those are valuation-limit calculations only. Rental coverage, property condition, borrower eligibility and other mortgage criteria may reduce the available amount further. The BRRRR cash snapshot can help compare refinance proceeds and capital left in the deal, using evidenced assumptions.
If all £137,500 principal remains outstanding for another two months at the example's simple rate, interest increases by £2,750, before extension fees or other contractual charges. Add any works overrun separately. Ask what cash or sale fallback repays the loan if both the valuation and timing deteriorate.
Evidence to obtain before committing
- A costed works schedule, contingency, contractor terms and evidence for the completed value.
- Confirmation of the initial net advance and conditions for every later release.
- A complete fee schedule, including legal, valuation, monitoring, drawdown and redemption costs where applicable.
- A supported sale or refinance exit with a lower-value and delayed-completion calculation.
- Written clarification of the facility's regulatory status. FCA PERG 4.4 sets out the regulated-mortgage test and exclusions; a refurbishment label does not decide the issue.
