External wall insulation

British Gas are working in partnership with local authorities and housing associations to provide external wall insulation in certain geographic areas.

External wall insulation is a layer of insulation fixed to the outside walls of your home and covered in a special type of plaster or cladding. Houses built before 1920s usually have solid rather than cavity walls. Solid walls tend to let more heat escape from the home than cavity walls. External wall insulation helps reduce the heat travelling through your home's walls helping you reduce your fuel bills and helping to make your home warmer in winter and cooler in summer - the new weatherproof coating can help enhance the look of your home.[2]

The benefits

  • Save up to £475 a year on your energy bills.
  • Hassle free installation project managed from start to finish.
  • Helps reduce heat loss.
  • Save around 1.9t of CO2 every year.

External wall insulation requires a little preparation but at British Gas we will take care of everything, we’ll handle delivery of the scaffolding, materials and skip, as well as arrange for
their removal.
