Introduction

There are many simple yet effective ways to insulate your home, which can significantly reduce heat loss while lowering your heating bills. 

Why

About a third of all the heat lost in an uninsulated home escapes through the walls and around a quarter through the roof. All that wasted energy costs money, as well as contributing to climate change. 

Lagging water tanks and pipes and insulating behind radiators also reduces the amount of heat lost, so you spend less money on hot water and it stays hotter for longer.  

In an uninsulated home, around one-third of the heat escapes through the walls 

How?

Loft insulation is cheap and simple to install and should pay for itself in a year through lower energy bills – 23 years if you pay somebody to do it for youLoft insulation should be fitted to a depth of 270 mm. 

If you have cavity walls and they are not insulated, this is a sound investment. Solid walls are harder to insulate – the options are external cladding or cheaper internal insulation. For a typical Victorian terraced house external cladding cost around £13,000 and internal insulation around £7,500 in 2020.  

Insulated wallpaper is not as good, but you’ll still notice a difference and it’s significantly cheaper.
