There are 3 routes to qualifying for a Great British Insulation grant.

  • The “low income” Group.
  • The LA Flex route.

You need to say Yes to the following 2 questions to qualify.

  1. Is your Council Tax Banding in Wales an A, B, C, D or E (or in England A to D). If you don’t know, you can find your Council Tax Banding on Gov.Ukand
  2. Is your EPC (Energy Performance Certificate) rating a D, E, F or G. You can find your EPC on the EPC Register. Don’t worry if your property doesn’t have an EPC – we can take care of that.

2 yeses and you qualify.

These rules apply to both owner-occupiers and privately renting tenants.

However, the Government have decided that if you are a privately renting tenant and you want cavity wall insulation or loft insulation you will need to receive a qualifying benefit. You will not require a qualifying benefit if you want Internal Wall Insulation.

The personal qualification criteria for the “low income” group, is that you are in receipt of a qualifying Government Benefit. Your EPC (Energy Performance Certificate) must still be a D, E, F or G rating.

This is a list of the qualifying benefits.

  • Pension Credit 
  • Income Based Job Seekers Allowance
  • Universal Credit – No income threshold
  • Income Related Employment and Support Allowance
  • Tax Credits (including Working and Child Tax Credits) – No income threshold
  • Income Support 
  • Housing Benefit – NEW
  • Child Benefit/Family Allowance. Income Thresholds apply

LA Flex stands for Local Authority Flexible Funding. However, it is not Local Authority funding it is ECO funding managed by the utility companies.

The Government has set up a different set of criteria for qualification which the Local Authorities manage.
