There are two main ways to use your mortgage to fund home improvements. A further advance means borrowing additional money from your existing lender, secured against your home. A remortgage to raise capital means switching to a new lender and borrowing more than your outstanding balance — releasing equity for the works.
Both options typically offer lower interest rates than unsecured personal loans, because the borrowing is secured against the property. However, you'll be increasing your total debt, and it's important to make sure the monthly payments remain affordable.
The viability of both options depends on your current loan-to-value (LTV) ratio. If your property has increased in value since you bought it, you may have built up significant equity that can be released.
A further advance is simpler and faster — you stay with your current lender and add to your existing mortgage. A full remortgage can access better rates and more equity but involves more process. If you're approaching the end of a fixed deal, a remortgage often makes more sense. We'll compare both.
It depends on your property's current value and your outstanding mortgage balance. Most lenders will advance up to 85–90% LTV for home improvements. We'll get your property valued and confirm exactly how much is available.
That's ultimately a question for a surveyor or estate agent — but extensions, loft conversions, and kitchen upgrades typically add measurable value. We'll help you think about whether the borrowing makes financial sense in the context of the property's overall value.
