Home energy grants

Around a third of carbon emissions in the borough come from residential properties and energy costs can have a significant impact on household budgets. The council is keen to support residents to improve the energy efficiency of properties and, in doing so, reduce carbon emissions. We often run schemes to provide financial support to upgrade homes.

The best way to reduce bills and carbon emissions is to install energy efficiency measures, such as insulation, or by using renewable technologies such as solar panels and heat pumps. Interested residents should note that eligibility requirements differ between the schemes and this page will be updated with new schemes when they are available.

If you are interested in registering for any schemes please click the links below and follow the instructions to register.

Current Schemes

Please check this page regularly for updates on upcoming schemes. You can also find updates on the council's social media on Facebook and Twitter.

The Royal Borough of Windsor & Maidenhead is currently supporting two schemes aimed at low-income households with homes that are difficult to keep warm.

Both schemes can help eligible homeowners, private tenants and landlords to improve the energy efficiency of their homes while reducing their energy costs and carbon footprint for free. If you are a landlord, you must have a maximum of four properties.

A survey will identify which scheme and the possible upgrades are suitable for your home. This will include a free updated Energy Performance Certificate (EPC) assessment.

If eligible, you may be offered one or more of the below installations: 

  • Insulation and ventilation upgrades to keep you warm in winter and cool in summer.
  • A low carbon upgrade to your current heating system.
  • Heating controls which make sure you only use heat when you need it.
  • An energy efficient hot water solution to keep your water warm for longer.
  • Photovoltaic solar panels to generate electricity.
  • Energy efficient lighting which has low running costs.

To help you determine which scheme is best for you please follow the flow diagram and then refer to further details on the relevant scheme below. Where you are not eligible for the schemes please check the Here to Help website.
