Reasons why you will not be eligible for cavity wall insulation

There are a number of reasons your home may not be eligible for cavity wall insulation:

  • Your property was built before 1924 or after 1982.
  • The walls have already been filled with blown Insulation –  you will see refilled holes as highlighted by the red circle in the image.
  • You live in a flat and do not have the agreement of neighbours above and below.
  • There are any signs of damp on the inside or outside of the walls. This can be rectified before applying for cavity wall insulation.
  • The property is timber/steel framed, concrete or stone, however you may be able to insulate them in the same way as a solid wall – contact the National Insulation Association (NIA).
  • Ventilation is inadequate and a vent cannot be fitted.
