How Insulating Your Loft Can Help To Save on Energy Bills

How insulating your loft can help to save on energy bills

What is loft insulation and how can it help you to save on your energy bills?

Loft insulation is where a barrier made from different materials, is installed into your loft space to help trap heat, making your home warmer. For example, insulation rolls can be made from glass fibre, sheep wool, or mineral wool. You can also get different types of insulation, such as insulation boards, insulation slabs, or foil insulation.

Insulation rolls are normally installed between the joists horizontally, whereas insulation boards are normally installed vertically, between and over the rafters.

A quarter of the heat in an uninsulated home is lost through the roof. Insulating your roof can help to keep your home warm, and save on energy bills. Loft insulation has a life span of around 40 years, and if installed correctly, will pay for itself many times over. It can also help to reduce your households carbon footprint significantly, by reducing huge amounts of C02 produced every year from your home.

How much does loft insulation cost to install, and how much can you save on your energy bills?

Loft insulation can cost around £300-£400 to install professionally, and from £150-£250 to DIY it. This can then help you to save around £115-£215 a year (depending on the house) on your energy bills, meaning the installation costs of the insulation will be paid off in a few years.

The annual savings you could make on your energy bills as estimated by the Energy Saving Trust:

  • Detached house - £215
  • Semi-detached house - £130
  • Mid-terraced house - £115
  • Detached bungalow - £185
