Insulating your home helps save energy, is good to the environment and also saves money on increasing utility bills. Insulation helps to keep you comfortable all year round by stopping the heat escaping and keeping the cold out in the winter, and keeping cool air in and the heat out in the summer.

Our Greener Living section has an interactive house for you to explore around to see where improvements can be made. We have also produced a technical guide to give a more detailed overview of areas of the home that can be insulated and what to consider when planning insulation works. 

The biggest areas of your home exposed to the elements are the walls. It therefore stands to reason that biggest savings can be achieved by insulating walls, whether cavity or solid.

The next biggest area is usually the loft and this is often the simplest and cheapest to insulate and therefore provides a quick return on any investment. It is recommended that you have 27cm (about 11 inches) of insulation in your loft.  Even increasing insulation from 12 to 27cm can save you £25 a year on your heating bills and keep you warmer. There may be funding available for some insulation measures, particularly cavity or loft insulation. Contact your energy supplier to see if they offer support for insulation measures. In addition some local authorities may offer grants.

Further savings can be made by insulating floors, insulating pipes and tanks, adding radiator reflector panels, and replacing or draught proofing windows and doors. All of these can improve the thermal efficiency of your home, how quickly your home cools down once the heating is turned off and how quickly it heats up once it is turned on.  The Energy Savings Trust energy calculator helps putting these tasks into financial and carbon dioxide savings perspective.
