Save energy and reduce your energy bill by insulating your home with loft and cavity wall insulation
Home insulation could enable you to save energy and reduce your energy bill by up to £390/year*. A typical house can lose half of the heat through the walls and loft. If your house has a cavity wall, but no insulation, you could benefit from installing cavity wall insulation. Similarly the recommended level of loft insulation is 270mm; if you have less than 160mm, you would benefit from insulating your loft to prevent heat loss through your roof.

Generally, homes built between 1930 and 1995 have empty cavity walls. Cavity wall insulation simply involves filling the cavity with an insulating material, usually by drilling small holes in the wall and injecting the insulating material until the cavity is filled. Depending on the size of your home this process usually takes around 2-3 hours.
Costs can be as low as £149 (or free if you qualify) and you can save you up to £270 on your energy bills.
Loft insultation is an effective way to save energy and money on your energy bills and can cost as little as £149 (or free if you qualify). The current recommended level of loft insulation is 270mm (10.5"). If you have less than this or if you have no loft insulation at all you can benefit by losing less heat through your roof.
Insulating your loft, simply involves laying rolls of mineral wool fibre (or some other insulating material) between and across the joists in your roof space and the work usually takes around 1-2 hours depending on the size of your property.
