Renovating a kitchen, extending a home or replacing an old roof all come with one shared challenge: working out how to pay for it. The right financing choice depends on the size of your project, your credit profile and how quickly you want the debt cleared. This guide walks through the six main ways UK homeowners fund improvement work, what each option actually costs, and how to compare offers properly before you sign anything.
What Is Home Improvement Financing?
Home improvement financing is any borrowing arranged specifically to pay for renovation, repair or extension work on a property. It ranges from short-term personal loans for a bathroom refit to long-term secured borrowing, such as a remortgage, for a full extension. The right choice balances three things: how much you need, how long you want to take repaying it, and how comfortable you are putting your home up as security.
6 Ways to Fund Your Home Improvement Project
1. Personal (Unsecured) Loan
A personal loan is not tied to your property or any other asset. Lenders base approval and rate on your credit history and income, not on collateral. It suits smaller, well-defined jobs, such as new flooring or a kitchen update, typically over one to seven years. Because there is no security involved, rates tend to sit higher than secured borrowing, though for many homeowners the simplicity and speed of approval make it worth it.
2. Secured Loan
A secured loan uses an asset, usually your home, as security for the lender. Because the lender has recourse to that asset if repayments stop, rates are generally lower than unsecured borrowing. This makes secured loans better suited to larger projects with a clear budget, but it also means your home is genuinely at risk if you cannot keep up repayments, so affordability checks matter more here than with any other option.
3. Remortgaging to Release Equity
If your property has increased in value or you have paid down a good portion of your mortgage, you may be able to remortgage and release some of that equity to fund the work. Repayment is usually spread across the remaining term of your mortgage, often fifteen to thirty years, which keeps monthly costs low but can add a significant amount of interest over the full term. It is worth running the total cost, not just the monthly figure, before deciding.
4. Home Equity Loan
A home equity loan gives you a lump sum secured against the value already built up in your property, usually at a fixed rate. It works well when you know the exact cost of the project upfront, such as a priced extension quote. As with any secured borrowing, missing payments puts your home at risk, so lenders will want to see clear evidence of affordability.
5. Home Equity Line of Credit (HELOC)
Rather than a single lump sum, a HELOC gives you a flexible credit line secured against your home that you draw from as needed. This suits phased renovations where the total cost is not fully known at the outset. Rates are usually variable, so repayments can rise if the Bank of England base rate increases, which is worth factoring into your budget.
6. Retailer or Contractor Finance
Some larger home improvement retailers and contractors offer zero or low interest finance for a fixed introductory period. These can be genuinely good value if you can clear the balance before the offer ends. Check what the rate becomes afterwards, since that is where costs commonly catch people out. Any credit agreement offered this way should be through an FCA regulated lender, and it is worth checking the Financial Conduct Authority register if you are unsure.
How Much Should You Budget Before Applying?
Price the full project first, then add a contingency of ten to twenty per cent for the unexpected extras that renovations tend to uncover, such as old wiring, damp or structural surprises behind a wall. If you are still at the planning stage, our interior design process guide breaks down each stage of a project and where costs typically fall, which is a useful reference before you approach any lender.
- List your total costs: materials, labour, permits and a contingency buffer.
- Check affordability: add up your monthly outgoings, including your existing mortgage, before deciding what you can realistically repay.
- Compare three or four lenders: rates, fees and terms vary more than most people expect.
- Read the small print: confirm whether the rate is fixed or variable and what happens if a payment is missed.
How to Choose the Right Option for Your Project
As a general rule, smaller and shorter jobs suit unsecured personal loans or retailer finance, while larger renovations with a longer payback horizon suit secured loans, home equity borrowing or remortgaging. If you are unsure which route fits your situation, free and impartial guidance is available from MoneyHelper and Citizens Advice, both of which offer independent comparisons that are not tied to any single lender.
Once your budget and financing are confirmed, planning the design itself is the next step. Our home interior design guide covers styles, layout and practical decisions, and if flooring is part of your project, the flooring and roofing section of the site has dedicated guides for common jobs, including hardwood installation.
Frequently Asked Questions
What is the cheapest way to finance a home renovation?
For smaller projects, retailer finance with a genuine zero interest period is usually the cheapest option if you can clear the balance in time. For larger projects, secured borrowing generally carries a lower rate than an unsecured personal loan, though it puts your home at risk if repayments are missed.
Can I get a loan for home improvements with bad credit?
It is possible, though rates are usually higher and lenders may ask for a guarantor or additional security. Checking your credit report before applying, and correcting any errors, can improve the rates you are offered.
Is it better to remortgage or take out a personal loan for renovations?
Remortgaging tends to suit larger projects where you want the lowest possible monthly payment, spread over a long term. A personal loan tends to suit smaller, well-defined jobs you want cleared within a few years, since the total interest paid is usually lower over a shorter term.
How much contingency should I budget for a renovation?
Most experienced renovators recommend adding ten to twenty per cent on top of your priced quote to cover unexpected issues, particularly in older properties.
Do I need to use an FCA regulated lender?
Yes. Any consumer credit agreement in the UK, including personal loans, secured loans and retailer finance, should be provided by a lender authorised by the Financial Conduct Authority. You can check a firm’s status on the FCA register before agreeing to any borrowing.
