External Wall Insulation

External wall insulation is a cost-effective way to improve the energy efficiency of homes and buildings. The process involves applying insulation material to the exterior walls of a property and then covering it with a protective layer.

This can be done for a variety of reasons, including reducing energy bills, improving the appearance of a property and increasing the property value. One of the main benefits of external wall insulation is that it can significantly improve the thermal efficiency of a property, this means that less heat is lost through the walls, keeping it warmer in the winter and cooler in the summer. It can also help to reduce noise pollution from outside and can protect walls from damp and weather damage.

Overall, external wall insulation is a great investment for anyone looking to increase the energy efficiency and value of their property,


  • Can be applied without disruption to the household.
  • Does not reduce the floor area of your home.
  • Renews the appearance of outer walls – with various finishes/colours available, such as brick slips, pebble dash and render.
  • Improves weatherproofing and sound resistance.
  • Fills cracks and gaps in the brickwork, which will reduce draughts.
  • Increases the life of your walls by protecting the brickwork.
  • Reduces condensation on internal walls and can help prevent damp (but will not solve rising or penetration damp).
  • Is best installed at the same time as external refurbishment work to reduce the cost.
  • May need planning permission – check with your local council.
  • Requires good access to the outer walls.
  • Is not recommended if the outer walls are structurally unsound and cannot be repaired.

Grant Funding

Grant funding may be available for the works and the amount of grant and the cost of the works will vary depending your eligibility and on how much CO2 is saved by installing the measure
