What is Sustainable Warmth Funding?

Upgrading Energy Inefficient Homes

The Sustainable Warmth Competition encompasses two existing schemes:

  • Local Authority Delivery Phase 3 (LAD3): £287 million to support low-income households heated by mains gas
  • Home Upgrade Grant Phase 1 (HUG1): £152 million to support low-income households off the gas grid

The focus of the schemes is on upgrading the worst insulated owner-occupied homes with energy efficient installations, low carbon heating and renewable energy. Homes with an Energy Performance Certificate (EPC) of E, F or G are prioritised. Upgrades to properties with an EPC of D are allowed but will be limited. City Energy have secured funding across the following areas:

  • Bedfordshire
  • Berkshire
  • Buckinghamshire
  • Hampshire
  • Oxfordshire
  • Swindon & Wiltshire (HUG only)


If you live in one of these areas, you could be eligible to have up to £25,000 worth of work installed at your home completely FREE of charge. Typical measures you could get through the scheme are loft insulation, cavity wall insulation and solar panels.


Who is Eligible for Funding?

To be eligible for the funding, you must meet the eligibility criteria. This includes:

  • Have a gross household annual income of less than £30,000 OR be in receipt of an income related means tested benefit
  • Properties will need to have an EPC rating of band D, E, F and G homes
  • Must be domestic dwellings – primary focus will be to upgrade privately owned housing

If you are a low income household and own your home it is possible to get upgrades fully funded within the relevant cost caps and you do not have to contribute.
