External solid wall insulation
If your home was built before 1930 it will most likely have solid external walls with no cavity.
Up to 45% of the heat from your home can escape through the walls if they are not insulated. External solid wall insulation works by adding a thermal layer of material to the exterior walls. The insulation slows down the rate at which heat is lost through the walls. It’s a bit like wrapping your home in a blanket to keep it warm.
Insulating these walls will keep the warmth in the house for longer and makes homes more comfortable and cheaper to heat.
If you’re not sure whether you have the right type of walls, our assessors will be able to identify whether your house is built with solid or cavity walls when they visit your home to undertake an assessment.
A fact sheet about external solid wall insulation from Centre for Sustainable Energy is available here
If you decide to go ahead with having external wall insulation installed, you will need to find out whether you need planning permission or not. If you do need planning permission, this will need to be in place before any works can commence. More information about solid wall insulation and planning is available here.
