Green Homes Grant home insulation

Free cavity wall and loft insulation for your home

We're offering our residents' cavity wall insulation and/or loft insulation, for free.

Hurry, though; this offer is only available to a very limited number of homes and for a very limited time period.

To get the free insulation, you must:

  • have a household income of less than £30,000 a year
  • have an EPC (energy performance certificate) rating for your home of E, F or G

Apply for free insulation

Why you should insulate

Insulating your home can:

  • save you money on your energy bills
  • make your home warmer and cosy
  • reduce your carbon emissions
  • increase your energy efficiency 
  • give you peace of mind, with insurance-backed guarantees

If it's free, who pays for it?

It's paid for by the Green Homes Grant (provided by the government). This is available to improve the energy efficiency of older, poorly insulated, homes.

Watch the two videos to hear how two residents have benefited from having their park homes insulated through the scheme.

After you've applied

Before work can start

If you're having loft insulation, your loft:

  • must be cleared of all possessions
  • must be accessible by an existing loft hatch
  • can't be insulated, if it's already boarded or converted to habitable rooms

If you're having cavity wall insulation:

  • cavity walls must not already be insulated
  • access to all external walls is required
  • the condition of the brickwork and mortar on the external walls will be assessed
  • the property will be assessed for ventilation and where necessary, mechanical and/or background vents will be replaced/installed

Who does the work?

Cornerstone, a Trustmark-approved contractor, will do the work. Cornerstone will contact you to arrange a site survey, produce an EPC and do the work.

After the work is finished

After the work is complete, another EPC will be done. This is to show the improvements in energy efficiency for your home. You'll also have the chance to check you're happy with the work and provide feedback.


The cavity wall insulation is guaranteed for 25 years.

The loft insulation is guaranteed for 2 years.
