How to Finance a Home Renovation UK: Loans, Remortgage & Grants
Every Funding Option Compared for UK Homeowners
Quick Answer
UK homeowners have 7 main ways to finance a renovation: savings, personal loans, secured loans, credit cards, remortgaging, further advances, and equity release. Personal loans suit projects under £25,000. Remortgaging or further advances suit larger projects. Government grants like ECO4 and BUS cover specific energy upgrades.
Most UK homeowners cannot pay for a full renovation from savings alone. A mid-range kitchen can be £15,000. An extension can reach £50,000. A full house renovation often crosses £100,000. Understanding your finance options before you start can save thousands in interest and protect your home from overextension.
This guide covers every major way UK homeowners fund renovations in 2026: personal loans, secured loans, remortgaging, further advances, equity release, credit cards, and government grants. Each has different costs, risks, and best-use scenarios.

What Each Option Actually Looks Like
Each finance type has a different shape: rate, term, security, speed, and what happens if things go wrong. Expand each card for the detail that matters.
Government Grants for Renovations
UK government grants focus on energy efficiency. If your project includes insulation, heating upgrades, or moving off fossil fuels, check these first. You may not need to borrow at all for those specific measures.
| Grant | Covers | Amount | Eligibility |
|---|---|---|---|
| ECO4 | Insulation, heating upgrades | Up to £20,000+ | Low income or certain benefits, EPC D-G |
| Great British Insulation Scheme | Cavity wall, loft insulation | Partial or full cost | EPC D-G, specific council tax bands |
| Boiler Upgrade Scheme (BUS) | Air source heat pump, ground source heat pump, biomass | £5,000 to £7,500 | Own the property, replacing fossil fuel heating |
| Home Upgrade Grant | Wide range of energy efficiency | Up to £10,000 | Off gas grid, lower income, EPC D-G |
| Local Authority Grants | Varies by council | Varies | Check your local council website |
Grant schemes change over time and eligibility criteria vary. Always check the latest information on GOV.UK and from your local council before planning around a grant.
How to Choose the Right Option
The right option depends on four factors. Work through them in order.
1. Project Size
- Under £5,000: savings or 0% credit card
- £5,000 to £25,000: personal loan
- £25,000 to £50,000: secured loan, further advance, or remortgage
- £50,000+: remortgage, further advance, or combination
2. Your Current Mortgage Situation
- Mortgage deal ending soon: remortgage is efficient (bundles renovation cost into new deal)
- Mid-deal with Early Repayment Charges: further advance avoids breaking deal
- No mortgage (owned outright): secured loan or equity release
3. Risk Tolerance
- Unsecured borrowing (personal loan, credit card): higher rate but does not risk home
- Secured borrowing (secured loan, remortgage, further advance, equity release): lower rate but home is at risk if you default
4. Energy Efficiency Work?
- Check grants first: ECO4, BUS, Home Upgrade Grant, Great British Insulation Scheme
- You may not need to borrow at all for specific measures
- Even partial grants reduce the amount you need to borrow
Remortgaging vs Further Advance
These are the two most common options for larger renovations. They look similar but behave very differently in practice. The right one depends mostly on where you are in your current mortgage deal.
Remortgage
- Replace entire mortgage with new lender or product
- Best when current deal is ending (no Early Repayment Charge)
- Full affordability assessment
- Fees: £500 to £2,000 typical (product fee, legal, valuation)
- Timeline: 6 to 12 weeks
- Usually the lowest rate available on the market
Further Advance
- Additional loan from current lender, existing mortgage untouched
- No Early Repayment Charge issues on your main mortgage
- Still full affordability check
- Fees: usually lower (£100 to £500)
- Timeline: 2 to 6 weeks
- Rate: usually slightly higher than best remortgage deals
Quick Rule of Thumb
If your current mortgage deal is ending within 6 months, remortgage. If you are locked into a fixed deal with Early Repayment Charges and the renovation cannot wait, a further advance is usually cleaner.
Mistakes to Avoid
Five expensive mistakes UK homeowners make when arranging renovation finance. Avoid these and you will save thousands.
Taking out finance before getting final quotes
Builders can vary by 30 to 50 percent on the same scope of work. Do not borrow until you know real costs. Borrowing too much means paying interest on money you never needed.
Using credit cards for large projects thinking you will pay them off
0% promo rates end and rates jump to 20 percent or more. Only use credit cards for small projects with a clear payoff plan that fits well inside the promo period.
Not shopping around for mortgage deals
Going to your current lender first is common but often not the cheapest. A mortgage broker (typically free to use) compares across the market and may find materially better rates.
Forgetting fees
Product fees, legal fees, valuation fees, Early Repayment Charges. Always calculate total cost over the life of the loan, not just monthly payment. Cheap rates can hide expensive fees.
Skipping the grants research
ECO4 or BUS can fully or partially fund significant energy work if you are eligible. Check government websites before taking out loans for energy measures. Borrowed money you did not need is the most expensive money of all.
