Home improvement loans are among the most common reasons UK homeowners borrow, whether for a new kitchen, an extension, or essential repairs. Used strategically, home improvements can genuinely boost your property's value — but not every project offers a good return, and the right way to finance it depends on the size and nature of the work.
Ways to finance home improvements
- Unsecured personal loan: Straightforward, fixed monthly payments, no additional security needed — usually the simplest route for small to medium projects.
- Further advance from your existing mortgage lender: Borrowing more against your home from your current lender, often at mortgage-comparable rates, but secured against your property.
- Remortgaging to release equity: Switching to a new mortgage deal for a larger amount, releasing the difference as cash — worth comparing against a further advance.
- Second charge mortgage: A separate secured loan against your home, useful if remortgaging isn't attractive due to your existing deal. See our second charge mortgage guide.
- Savings: Using cash reserves avoids interest entirely, though it's worth weighing against keeping an emergency fund intact.
Which improvements tend to add the most value?
Value uplift varies by property, location and local buyer expectations, but improvements that are consistently associated with adding value in the UK market include well-executed kitchen and bathroom renovations, loft conversions that add a genuine extra bedroom, and extensions that add usable living space, particularly where they bring the property in line with — or ahead of — comparable local homes. Energy efficiency improvements (insulation, double glazing, heat pumps) are increasingly valued too, both for running-cost savings and rising buyer awareness of Energy Performance Certificate ratings.
Improvements that often don't pay for themselves
- Very high-specification finishes that exceed what buyers in your local area typically expect or are willing to pay for
- Swimming pools and highly niche features with narrow buyer appeal
- Over-personalised décor or structural changes that reduce a property's general appeal (for example, removing a bedroom to create one large room)
How to budget and borrow sensibly
- Get multiple quotes from tradespeople before finalising a budget, and build in a contingency of at least 10-15% for unexpected costs
- Compare unsecured loan rates against a mortgage further advance or remortgage, particularly for larger projects (typically above £25,000-£35,000, where secured borrowing often becomes more competitive)
- Avoid over-improving relative to your local area's typical property values — ask a local estate agent for an honest view before committing to major structural work
- Check whether planning permission or building regulations approval is needed, and factor any related costs and delays into your borrowing timeline
Comparing loan offers for home improvements
As with any borrowing, compare the representative APR, total amount repayable, and any arrangement fees across several lenders. Our Loan Repayment Estimator lets you quickly see the monthly and total cost for different loan amounts and terms, helping you judge what's genuinely affordable before committing to a renovation budget.
The bottom line
Home improvement loans can be a smart way to fund renovations that both improve your quality of life and add genuine property value — but borrowing should be matched sensibly to the project size, with secured options considered for larger sums, and a realistic view of which improvements actually pay off in your local market.
