Home energy conservation

We are committed to achieving significant improvements in domestic energy efficiency for local residents.

Improving the energy efficiency of our homes has many benefits:

  • Making our homes warmer in the winter and cooler in the summer
  • Saving on fuel bills, making our homes more affordable to heat
  • Reducing carbon dioxide emissions which contribute to climate change.  Emissions from housing contribute up to a third of the carbon dioxide emitted in the UK.
  • Reducing the use of finite fossil fuels (coal, oil and gas)

Cavity wall and loft insulation are simple and cheap measures to improve the insulation standard of your house. Whether you own or rent your home you may qualify for free cavity wall insulation through the Energy Company Obligation scheme. Visit our Warm and Safe Wiltshire webpage for more about home insulation and the current support available.

Energy Company Obligation Scheme and Great British Insulation Scheme – Flexible Eligibility

The Energy Company Obligation (ECO4) and the Great British Insulation Scheme (GBIS) are obligations on energy suppliers to deliver energy efficiency and heating measures to domestic premises.

The ECO4 scheme will focus on supporting low income and vulnerable households. The scheme will improve the least energy efficient homes helping to meet the Government’s fuel poverty and net zero commitments.

The Great British Insulation Scheme will support the ECO4 scheme in the delivery of predominantly single measures targeted at a wider range of households.

The flexible approach for Local Authorities to identifying fuel poor and vulnerable households who may benefit from heating and energy saving measures is referred to as “ECO4 Flex” and “Great British Insulation Scheme Flex”.

The following documents detail how we will identify households as eligible and what criteria we will use.

Current version

Version 6 is the current version and should be used from 9 October 2023. Version 6 has superseded Version 5, which ran from 23 February 2023 to 8 October 2023.

Previous versions

The Home Energy Conservation Act 1995 requires English Local Authorities to prepare and publish a report every two years, starting from 2013.

The report sets out the energy conservation measures that the Authority considers practicable, cost-effective and likely to result in significant improvement in the energy efficiency of residential accommodation in its area.

Reporting is to continue up to and including 31 March 2027.
