ECO-Flex: Grant Towards Domestic Energy Efficiency Improvements

The Energy Company Obligation (ECO) is a grant scheme allowing energy efficiency improvements for residents in fuel poverty or who are vulnerable.

The Council has published a Statement of Intent allowing delivery of this scheme in Pembrokeshire.

If your home (rented or owner-occupied) is energy inefficient, and you either spend more than 10% of your income on fuel or are vulnerable to the cold, you may be entitled to a grant towards home energy efficiency measures involving heating upgrades and insulation.

Grants are administered by agents working on behalf of energy companies. Agents collect client details, perform home energy surveys and arrange works for successful applicants.

The Councils involvement is to simply vet applications, ensuring qualifying conditions are met. The final decision on whether a household receives a measure and the level of grant available under flexible eligibility or other ECO funding streams will be made by the energy company or their agent.

For more information, please email:

Unfortunately, the scheme does not apply to Social Housing tenants.

Landlords and members of the public – please do not submit an application form to us yourself, it requires the partnership of an energy company or their agent before you do this, please email us for further details.

Nest (Wales)

Nest is the Welsh Assembly Government’s New Fuel Poverty Scheme and British Gas is the delivery partner for the scheme.

The programme is designed to make private sector households warmer and healthier places to live. The scheme offers householders a range of free home improvements to help them heat their homes more efficiently and stay warm without facing huge energy bills.

The Nest scheme takes a ‘whole house’ approach to determining what energy improvement work would be most suitable, some examples include:

  • Loft and cavity wall insulation
  • Solid Wall insulation
  • Draught Proofing
  • Boiler Replacement

To qualify for Nest you must be a private home-owner or private tenant, have a property with an energy efficiency rating of F or G and in receipt of one of the following means tested benefits:

  • Child Tax Credit where the household income is below £16,010
  • Council Tax Benefit (excluding the single person occupancy reduction)
  • Housing Benefit
  • Income Based Job Seekers Allowance
  • Income Related Employment and Support Allowance
  • Income Support
  • Pension Credit
  • Working Tax Credit where the household income is below £16,010

Not sure if your property qualifies, typically an F or G rated property would have all, or most, of the following characteristics:

  • No central heating or a central heating system with a very inefficient boiler. (Usually a boiler of 15 or more years old).
  • Homes heated by a fuel other than mains gas
  • Solid Walls
  • Un-insulated cavity walls
  • No loft insulation / less than 100mm
  • Single glazed windows

Also, detached, semi detached or end terraced properties are more likely to be F or G rated.
