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.

Your options compared

Three ways to raise the money.

Further advance

Borrow more from your current lender. Often quickest, keeps your existing rate on the original balance.

Remortgage

Switch lender and borrow more. Can access better rates, but may trigger early repayment charges.

Second charge loan

A separate secured loan alongside your mortgage. Keeps your existing deal intact.

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

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.

Photo ID and proof of address
Bank statements (usually 3 months)
Details of credit commitments
Existing mortgage statement
Builder quotes
Planning information if relevant
