Insulation and Heating Grants in Flintshire, Wales – 2023 Update

Flintshire Council have announced their support for the Energy Company Obligation scheme for eligible residents!

This is good news as it means that the Government’s Energy Company Obligation grant scheme can be accessed by residents of Flintshire. By supporting the scheme, the council have increased the number of people that are able to access grants. This includes anyone with a health condition, vulnerable residents and those with an income of less than £31K. Read on for more details to find out what you can get!

What grants are available in Flintshire?

The Energy Company Obligation grant scheme is now available to all Flintshire residents. Grants available through this grant program include:

  • Energy efficiency grants for eligible householders and landlords, including free energy assessments and installation of energy saving measures such as insulation, boilers and heating systems.
  • Renewable energy grants for households wishing to install heat pumps and, in limited cases, solar panels or other renewable technology for your Flintshire home.

What’s changed for 2023?

Flintshire Council published their Statement of Intent (SOI) for ECO4 Flex on 24th November 2022 at and this means that residents will be able to access grants throughout 2023. Without the Statement of Intent, residents wouldn’t have been able to apply through the eligibility pathway called ECO4 Flex, and they would only be eligible through the benefits pathway.

The two main ways to qualify are:

  1. Benefits eligibility – where applicants live in energy inefficient housing and are in receipt of certain benefits
  2. ECO4 Flex eligibility – where applicants are vulnerable, have a low-income or if they have a health condition made worse by living in a cold home

There are many councils in the UK that haven’t released ECO4 Flex details yet, so it is great that Flintshire have made the grants available to their vulnerable residents. If you’d like to skip to see if you are eligible, you can check if you qualify for grants here.
