Bridging Finance

Bridging Finance for Refurbishment and Development

From cosmetic updates to structural conversions, refurbishment bridging can fund works a mainstream mortgage won't cover — up to a point.

Written by Matt Stevens, Mortgage & Protection Adviser, The Mortgage Genie

The short answer

Bridging finance can fund light refurbishment and, with the right lender, heavier structural works or conversions, typically with funds for the works released in stages as work progresses. Larger ground-up development projects usually need a dedicated development finance facility rather than an ordinary bridge, because of the scale of staged drawdowns and monitoring involved. We can explain which route fits your project and discuss development finance as a separate facility where that's the better fit.

Start a bridging enquiry

Our service: Bridging enquiries are assessed internally by our team to understand your requirements and the appropriate route. Where referral to a partner adviser is needed, we will explain who they are, what information will be shared and any referral payment, and obtain your permission before sharing your details.

Light refurbishment

Light refurbishment covers cosmetic or non-structural work — new kitchens and bathrooms, redecoration, rewiring, or general modernisation — that doesn't require planning permission or building regulations sign-off for structural changes. This is the type of project most straightforward for bridging lenders to fund, often as a single advance rather than staged drawdowns.

Heavy refurbishment and structural work

Heavy refurbishment involves structural changes — removing load-bearing walls, extending, re-roofing, or significant works requiring building control sign-off. Lenders will typically want a detailed schedule of works, cost plan, and sometimes a monitoring surveyor involved, and may release funds in stages rather than as a single advance.

Conversions

Converting a property's use — for example splitting a single dwelling into flats, or converting a commercial building to residential — adds planning and building regulations considerations on top of the physical works. Bridging can fund conversions within the usual bounds of a bridging facility, but larger or more complex conversions may move into development finance territory.

How works funding is released in stages

Where a lender releases funds for works in stages, this is usually tied to verified progress — for example confirmed by a monitoring surveyor's inspection — rather than released upfront. It's important not to assume staged funding is automatically part of every bridging loan: some bridges fund the purchase only, leaving you to fund works separately, so always clarify this with your lender before planning cash flow around it.

Ground-up development: why it usually needs development finance

Building a new property from scratch is typically outside the scope of an ordinary bridging loan. Ground-up development usually requires a dedicated development finance facility, which is structured specifically around funding land, build costs and professional fees in stages linked to build progress, assessed against loan-to-cost (LTC) and loan-to-gross-development-value (GDV) ratios. We can discuss development finance as a separate facility if your project reaches this scale.

LTC (loan to cost) — the loan expressed as a percentage of the total cost of the project (land plus build costs plus fees).
LTV (loan to value) — the loan expressed as a percentage of the property's current value.
GDV (gross development value) — the estimated value of the finished, completed scheme.

Monitoring surveyor and cost plans

For larger or staged projects, lenders typically appoint an independent monitoring surveyor to review your cost plan, inspect progress, and confirm each drawdown is justified by work completed. This protects both you and the lender by catching cost overruns or quality issues early, though it does add a layer of process to manage.

Contingency, borrower experience and the overall budget

Lenders generally expect a contingency allowance within the budget to absorb unexpected costs, and will want to understand your relevant experience, particularly for heavier works or larger schemes. A realistic, well-documented budget with contingency built in makes a stronger case than an optimistic one that leaves no room for the unexpected.

Sale and refinance exits

Once works are complete, the usual exits are selling the finished property, or refinancing onto a standard residential, buy-to-let or commercial mortgage now that the property is in a mortgageable condition. Having a realistic view of likely post-works value and lender criteria is important before you start.

Risks: overruns, delays, valuation

Risk

Build cost overruns, delays, or a lower-than-expected valuation once works are finished can all affect your ability to repay the loan as planned. Budgeting conservatively, keeping contingency in reserve, and discussing a fallback exit with us before you start all help manage this risk. As with all bridging, the security property is at risk if the loan isn't repaid.

How our advice is paid for

Initial advice is free. If you go ahead, any fee will be explained and agreed with you in writing before chargeable work begins. A lender or finance provider may also pay commission.

We will assess your requirements and explain the finance routes that may be available. Where specialist support or an introduction is required, we will explain who will handle the case and any associated costs or commission.

Bridging enquiries are assessed internally by our team to understand your requirements and the appropriate route. Where referral to a partner adviser is needed, we will explain who they are, what information will be shared and any referral payment, and obtain your permission before sharing your details.

Frequently asked questions

Sometimes, but not always — some bridging loans fund the purchase only. Always confirm with your lender whether works funding is included and how it would be released before relying on it.

Light refurbishment is cosmetic or non-structural and usually simpler to fund. Heavy refurbishment involves structural work needing building control sign-off, and lenders typically want a detailed schedule of works and may use staged drawdowns.

Usually yes for ground-up development, because of the scale of staged funding and monitoring involved. We can discuss development finance as a separate facility once your plans are clearer.

This is a key risk with refurbishment and development projects. A realistic cost plan with contingency, and keeping us informed early if costs change, helps manage this — but ultimately the security property is at risk if the loan can't be repaid.
