Quick Answer: Best Home-Improvement Remortgage in 2026
Most mainstream lenders — Halifax, Nationwide, Santander, Barclays, NatWest — allow remortgaging to raise funds for home improvements, typically up to 85-90% LTV, with 'home improvements' being one of the most readily accepted reasons. You borrow at mortgage rates (around 4.5-5.5%) rather than personal-loan rates (8-15%), making it cost-effective for larger projects. Green/energy-efficiency upgrades may qualify for cheaper green remortgage deals. A broker maximises how much you can raise.

How Home-Improvement Remortgaging Works
You increase your mortgage to fund the project:
- Releasing equity — you remortgage for more than your current balance, taking the difference as cash to pay for the work. Your loan and LTV rise accordingly.
- Accepted reasons — home improvements are among the most lender-friendly reasons to raise capital; most won't query a reasonable kitchen, bathroom, extension or renovation.
- Value uplift — well-chosen improvements (extensions, loft conversions, kitchens) can add more to your home's value than they cost, partly offsetting the extra borrowing.
- Evidence — for larger sums, lenders may ask for quotes or plans; modest amounts are usually granted on declaration alone.
