Home Insulation Grants

The grant scheme is open to all homeowners in East Herts District.

If you've been excluded from subsidised schemes because you used lofts for storage or have presence of narrow wall cavities, it's worth considering applying.

The council can help towards the cost of home insulation by providing a

  • 50% grant of up to £200 towards loft insulation works which provides 270mm depth loft insulation and
  • 50% grant of up to £300 towards the cost of cavity wall insulation

Loft and cavity wall insulation are very important and have some of the fastest paybacks of any home insulation measure.
