Refurbishment Finance

Refurbishment finance is a type of short term loan used to fund the purchase and renovation of a property, or to fund renovation works on a property you already own. It falls under the broader category of bridging finance and is designed specifically for projects where the property needs work before it can be sold, let, or refinanced onto a longer term mortgage.

This guide covers the different types of refurbishment finance, how funds are released, what lenders look for, the costs involved, and how to plan your exit strategy.

Light Refurbishment vs Heavy Refurbishment

Lenders split refurbishment projects into two categories: light and heavy. The distinction is based on the scope and nature of the works, and it affects the loan structure, the interest rate, and the monitoring requirements.

Light Refurbishment

Light refurbishment covers cosmetic and minor works that do not alter the structure of the building and do not require planning permission. Typical examples include the following:

• New kitchen and bathroom installations
• Redecoration throughout, including new flooring, painting, and plastering
• Rewiring and replumbing
• New central heating systems or boiler replacement
• Replacing windows and doors
• Damp treatment and minor roof repairs
• Garden landscaping and external redecoration

Light refurbishment loans are simpler to arrange. The works do not usually require building regulations sign off beyond electrical and gas certificates, and the lender may release the refurbishment funds in a single drawdown or in two stages.

Heavy Refurbishment

Heavy refurbishment involves structural changes to the property. This category includes projects that alter the footprint, layout, or use of the building. Common examples include:

• Loft conversions and basement conversions
• Extensions, including single and double storey
• Removing or adding load bearing walls
• Converting a house into flats or an HMO
• Change of use, such as commercial to residential
• Full structural renovation of a derelict or uninhabitable property
• Adding additional storeys

Heavy refurbishment loans are more complex. They typically require planning permission and building regulations approval. The lender will want to see detailed schedules of works, costings, and often appoints an independent monitoring surveyor to sign off each stage before releasing the next tranche of funds.

How Funds Are Released

Refurbishment finance is not released as a single lump sum. The loan is structured in two parts.

Initial advance. The first portion of the loan covers the property purchase or, if you already own the property, is released against its current value. This is available at completion.

Refurbishment drawdowns. The remaining funds, earmarked for the renovation works, are released in stages as the work progresses. The number of stages depends on the project size and the lender.

For light refurbishment, some lenders release the full refurbishment amount in one or two drawdowns, sometimes on a day one basis if the works are minor. For heavy refurbishment, the funds are typically split into three to five tranches, released after the lender’s monitoring surveyor confirms each stage of work has been completed to an acceptable standard.

This staged drawdown process protects the lender by ensuring money is only released as value is added to the property. From the borrower’s perspective, it means you need to be able to fund each stage of work upfront and then reclaim the cost from the lender once the work is signed off. Some borrowers use their own funds or a facility with their contractor to bridge this gap.

LTV: Current Value vs Gross Development Value

Lenders assess refurbishment loans using two valuations.

Current market value. This is what the property is worth today, in its current condition. The initial advance is based on this figure. Most lenders will advance up to 70% to 75% of the current market value for the purchase or refinance element.

Gross development value (GDV). This is the estimated value of the property after the refurbishment works are complete. The total facility, including the refurbishment drawdowns, is capped as a percentage of GDV. Most lenders allow up to 65% to 70% of GDV for the total facility on a heavy refurbishment, and up to 75% on a light refurbishment.

For example, consider a property with a current value of £200,000 and a post works value of £300,000. The lender may advance 70% of the current value for the purchase, which is £140,000. The total facility including refurbishment costs may be capped at 65% of GDV, which is £195,000. This leaves up to £55,000 available for the refurbishment drawdowns.

Understanding how these two valuations interact is essential for structuring the deal correctly. If the refurbishment costs exceed what the lender will release based on the GDV calculation, you will need to fund the shortfall from your own resources.

Planning Permission and Building Regulations

For light refurbishment, planning permission is rarely needed. The works fall within permitted development rights in most cases. You will still need to comply with building regulations for specific elements, such as electrical work and gas installations, but a full building control application is not usually required.

For heavy refurbishment, planning permission is almost always necessary. If you are extending the property, converting its use, or making structural alterations, you will need to submit a planning application and receive approval before the lender will release funds for those works. Many lenders will require planning permission to be in place before they complete the loan.

Building regulations approval is required for all structural work. The local authority building control team or an approved inspector will need to sign off the works at various stages and issue a completion certificate when the project is finished. This certificate is important because it confirms the works are safe and compliant, and without it, you may have difficulty selling or refinancing the property.

Exit Strategies

Every refurbishment finance application needs a clear exit strategy. The lender wants to know how you plan to repay the loan when the term ends. The three most common exit strategies are as follows.

Sale of the property. You complete the refurbishment, put the property on the market, and repay the loan from the sale proceeds. This is the standard approach for property flippers.

Refinance onto a buy to let mortgage. You complete the works, achieve the target value, and refinance onto a long term buy to let mortgage. The BTL mortgage repays the bridging loan in full. This is the most common exit for investors pursuing a buy, refurbish, refinance strategy.

Refinance onto a residential mortgage. If the property is your intended home, you remortgage onto a standard residential mortgage once the works are complete and the property is habitable.

Lenders take the exit strategy seriously. A vague plan is not sufficient. They want to see evidence that the exit is realistic, whether that means a remortgage decision in principle, comparable sales data to support the GDV, or a clear timeline for completion of works and sale.

Costs and Fees

Refurbishment finance carries several layers of cost beyond the headline interest rate.

Interest rate. Monthly rates typically range from 0.55% to 1.0% per month for light refurbishment and 0.65% to 1.25% for heavy refurbishment. The rate depends on LTV, the property type, the borrower’s experience, and the lender.

Arrangement fee. Usually 1% to 2% of the gross loan facility.

Valuation fee. A surveyor will value the property in its current condition and provide a projected GDV. Fees range from £300 to £1,500 depending on the property.

Monitoring surveyor fee. For heavy refurbishment, the lender appoints an independent monitoring surveyor to inspect the works at each drawdown stage. Each inspection typically costs £250 to £500, and there may be three to five inspections over the project.

Legal fees. Borrower and lender solicitor costs combined typically range from £1,500 to £3,500.

Broker fee. Typically 1% to 1.5% of the loan amount.

Exit fee. Some lenders charge 1% of the loan on repayment. Not all lenders apply this, so check before committing.

Timescales

Refurbishment bridging loans can complete within 2 to 4 weeks from application. The speed depends on the complexity of the case, the valuation timeline, and how quickly legal work can be completed.

The total loan term is usually 6 to 18 months for light refurbishment and 12 to 24 months for heavy refurbishment. Lenders set the term based on your schedule of works and the expected time to complete the refurbishment plus the exit. Always build in a buffer; renovation projects frequently overrun.

Who Is Refurbishment Finance For?

Refurbishment finance is used by a range of borrowers, from experienced property developers to first time investors taking on their first renovation project.

Property flippers who buy below market value, renovate, and sell at a profit.

Buy, refurbish, refinance investors who renovate to increase value and then hold the property as a rental, refinancing onto a long term mortgage to recycle their capital.

Landlords who need to bring a property up to lettable standard, including meeting EPC requirements or HMO licensing conditions.

Homeowners who have purchased a property that needs significant work before they can move in.

Lenders are generally happy to work with both experienced and first time refurbishment borrowers, though first time applicants may face slightly tighter criteria or lower LTV limits.
