Yes – Properly insulating your property is one of the best ways to keep down the amount of money you spend on your energy bills. With insulation, you can save hundreds of pounds year on year.
On average, cavity wall insulation will save you around £255 a year in a detached house, £150 a year in a semi-detached house, and £95 on a terrace. If you have solid walls, you can save even more money: without insulation, on average, you’ll be spending around an extra £435 a year in a detached house and around £260 in a semi.
In a typical semi-detached property, loft insulation knocks around £135 a year off your energy bills.
