Energy bills can often make up a huge part of your monthly household outgoings, but there are some things you could do to help reduce the costs.

Cavity Wall & Loft Insulation


If your home is suitable, cavity wall and loft insulation could help you save up to £310** per year, and many companies even offer to install it for you for free as part of their obligations to energy efficiency^.

Cavity wall insulation works by filling the gap between the two layers of a buildings external wall, helping to keep warmth in and save energy. Most homes built after 1920 were built with cavity walls. Loft insulation works in a similar way as it helps to keep warmth in, but it can be even more effective as heat rises – up to a quarter of your heat could be lost through an un-insulated loft.

Before you begin this process, there are a few things to check. Not all homes are suitable for cavity wall or loft insulation. Some things that may make your home unsuitable are if:

  • You live in a housing association property or are a council tenant
  • You live in a flat
  • Your home is built from natural stone or concrete or has a timber or metal frame
  • You already have insulation (properties under 10 years old tend to already be insulated)
  • Most suppliers will carry out a survey to find out if your home is suitable.
