Borrowing for Home Improvements
“Your home has potential. Let’s unlock it.”
If you’re planning a renovation, extension, or major improvement, a further advance or remortgage could be more cost effective than a personal loan, particularly if your property has gone up in value.
Quick answer
You can fund home improvements by borrowing more against your home, through a further advance from your current lender, a remortgage to a new lender, or a second charge loan. Rates are usually lower than unsecured loans because the borrowing is secured. The main thing to know is that it increases your total debt, and your home is at risk if repayments aren’t kept up.
How borrowing for improvements works
A further advance adds a new loan with your current lender, often at a separate rate and on a separate product.
A remortgage replaces your mortgage with a bigger one from a new lender, which can be cheaper if your current deal is ending.
A second charge loan sits alongside your existing mortgage, useful when you want to keep a low rate you already have.
Funding different projects
Extensions and loft conversions often add value, and lenders may ask for plans and builder quotes.
Large projects may need staged funding or specialist lenders. Cosmetic updates are usually straightforward.
Eligibility and what lenders assess
Who may qualify
Homeowners with equity who want to improve the property they live in.
Equity and LTV
Most lenders cap total borrowing around 85% to 90%.
Income and affordability
Reassessed for the total new borrowing.
Credit history
Recent missed payments limit options.

Planning or building control may be needed for major works.
Common reasons for decline
Insufficient equity, or unclear purpose for the funds.

Costs, risks and when it may not be suitable
Being upfront about this is part of doing it properly.
Costs to budget for
- Product and arrangement fees
- Valuation and legal costs
- Early repayment charges if you leave a deal early
- The total cost of borrowing over the full term, not just the initial rate
- A longer term lowers monthly payments but increases the total interest you pay
Risks to weigh up
- Unsecured debt becomes secured against your home
- Works that overrun can leave you short of funds
- Your home may be repossessed if you do not keep up repayments on your mortgage
When it may not be suitable
- For small projects, an unsecured loan paid off quickly can cost less overall
- If you’re near the end of a fixed deal, waiting to remortgage may be cheaper than a further advance now
What you will need
The exact list depends on your lender, but this is what to start gathering.
