Cavity walls are constructed using two layers of brick with a space or cavity between them. Modern homes have insulation in the cavity, but houses built between 1924 and 1982 do not.

Installing cavity wall insulation can help maintain warmth and comfort levels in your home, keeping the cold out and the heat in. The insulation material, whether it is mineral wool, foam, or beads, should not be a concern. Our skilled and authorised surveyors will inspect your property to determine the best type of insulation for you. Additionally, we offer cavity wall extraction for inadequate insulation.

Emerald Green Energy can assist you in putting a stop to your central heating working overtime and 35% of heat escaping through your cavity walls by signing you up for the UK government’s FREE cavity wall insulation grant scheme. This scheme is designed to provide free cavity wall insulation to homes that do not have it.

You don’t need to know this in advance! Just take a moment to apply, and one of our surveyors will be around to inspect your property and keep you informed. Here are a few indicators that you will be suitable for a free cavity wall insulation grant:

  • The external walls are cavity walls
  • No cavity wall insulation currently fitted
  • Property has a 5cm wide cavity (or more)
  • Built before 1982 (even homes built before 2005 may qualify)
  • Brickwork, outer walls, and masonry in good condition
  • House not prone to flooding.
  • Walls not overly exposed to driving rain and harsh weather
