Question 1

What is the cheapest way to finance a home extension in the UK?

Accepted Answer

For most homeowners with mortgage equity, a remortgage or further advance is the cheapest route because it secures the borrowing against the property at mortgage rates rather than personal-loan rates. Always compare arrangement fees and overall cost.

Question 2

Can I use a personal loan for a £40,000 extension?

Accepted Answer

Personal loans typically cap at £25,000–£50,000 depending on lender and credit profile. They are quick to arrange but interest rates are usually 2–4× higher than secured borrowing. Suitable for smaller projects or top-ups.

Question 3

What is a bridging loan and when is it useful?

Accepted Answer

A bridging loan is a short-term (3–24 month) secured loan used when you need fast capital — for example to fund a refurbishment before refinancing onto a standard mortgage. Rates are high (typically 0.6%–1.2% per month) so always have a clear exit strategy.

Question 4

Are there government grants for home renovations?

Accepted Answer

Yes — schemes include ECO4 (energy-efficiency for low-income households), Boiler Upgrade Scheme for heat pumps, and local-authority disabled-facilities grants. None of these typically cover a standard extension or refurbishment.
