Financing Your Home Renovation

Bizzy DayPublished by Bizzy Day

A guide to financing home renovations in the UK — remortgaging, further advance, personal loans, green finance, and what each option means for your financial position.

Financing Your Home Renovation

Most significant home renovation projects require external financing — few homeowners have £30,000-£100,000 sitting available in cash. The right financing option depends on the size of the project, your existing mortgage, your equity position, your credit profile, and the interest rate environment.

Remortgaging to fund a renovation

If your home has increased in value since you took out your mortgage — or if you have paid down a significant portion of the capital — remortgaging to release equity is often the most cost-effective way to fund a large renovation. Mortgage interest rates are typically lower than personal loan or credit card rates, and spreading the repayment over a longer term reduces monthly cost. The downside is that you are securing additional debt against your home.

Further advance from your current lender

Many mortgage lenders offer a further advance — an additional borrowing on top of your existing mortgage, at either the same rate or a new rate. This avoids the cost and complexity of a full remortgage (which would include arrangement fees, solicitor fees, and valuation costs) if the current deal is still competitive. Ask your existing lender first before going to market.

Green renovation finance — specifically green mortgages and improvement loans tied to energy efficiency upgrades — is growing rapidly. Lenders are increasingly offering preferential rates for homes that meet minimum EPC standards.

Personal loans

For smaller projects (typically under £25,000), a personal loan avoids the need to remortgage and does not secure debt against your home. Interest rates are higher than mortgage rates — typically 5-15% depending on your credit profile and the lender — and repayment terms are shorter (usually 1-7 years). Personal loans are most suitable for projects where the cost is known and the renovation is complete within a short timescale.

Government-backed green finance

The UK government has introduced several schemes to finance energy efficiency improvements: the Boiler Upgrade Scheme (grants for heat pumps), the Great British Insulation Scheme (free or subsidised insulation for eligible households), and the ECO4 scheme. The Green Homes Grant Scheme ended in 2021, but similar schemes may be reintroduced. Always check current eligibility before funding energy improvements yourself.
