For the first time this year, we actually had to scrape the frost off our van’s windscreens this morning. The cold winter weather has well and truly hit. So, while we all rush out to buy our hats, gloves and scarfs to keep ourselves warm, what about considering how to keep our home warm as well? (without excruciating heating bills).

The main area where homes lose heat is through the walls and the roof. Studies have shown that some houses lose as much as 1/3 of their heat through the walls and as much as ¼ of their heat through the roof. Other areas of heat loss include windows, doors and floors.

To try to minimalise this heat loss, you need to ensure that your loft and walls are fully insulated.


Lost insulation is fairly easy to install and once completed, can last for up to 40 years.

To fit lost insulation, you have to lay down insulation blankets, sometimes referred to as ‘quilts’, across the surface of the roof. These quilts should be at least 270mm thick. If you already have insulation, you should check that they meet this minimum thickness level, and if not, you should be topping it up.

The most common material used for quilts are foil-backed felt, glass or mineral fibre. However, more environmentally friendly materials are cork, straw and wood board.


Most houses built after 1990 should have been built with wall insulation included, however this is not so common in older houses. The type of insulation you will need will depend on the type of wall you have. Cavity walls are the easiest to insulate, and are the most common walls in houses built post-1920.

To insulate solid walls you have to place insulation on the external or internal side of the wall to keep the heat in. This tends to cost more than insulating a cavity wall, but normally gives you higher savings on your heating bill. Other types of wall, such as steel-frame, timber-frame or prefabricated concrete will not have a cavity, so you may be able to insulate them in a similar way to solid walls, though it’s always best to speak to a specialist to insulate a non-standard wall.

We recommend always using an expert to fit wall insulation.
