Home Improvement Loans UK Calculator FAQ
Everything you need to know about home improvement loans, repayment calculations, and financing your next renovation project.
A home improvement loan is a sum of money borrowed to pay for renovations, extensions, or upgrades to your property, such as a new kitchen, bathroom, extension, or energy efficiency improvements. It is repaid in fixed monthly instalments over an agreed term.
Monthly repayments are calculated using the loan amount, the annual interest rate, and the loan term, spreading the capital and interest evenly across fixed monthly instalments. This calculator applies the standard amortising loan formula to estimate your repayment.
An unsecured home improvement loan is not tied to your property and is typically used for smaller amounts, while a secured loan is backed by your home as collateral, which can allow for larger amounts and sometimes lower rates, but puts your property at risk if repayments are missed.
Rates on UK home improvement loans vary widely depending on the lender, loan amount, term, and your credit profile, and can range from around 6% to 20%+ APR for unsecured loans. Always compare the representative APR across lenders before applying.
Many UK lenders allow early repayment, though some may apply an early settlement fee, often capped at up to two months’ interest under UK consumer credit rules. Check your specific loan agreement for the exact terms.
An unsecured home improvement loan is separate from your mortgage and does not affect it directly, though the extra monthly commitment will be considered in future mortgage affordability assessments. A secured loan, by contrast, sits alongside your mortgage against the same property.
