Applications for a grant are welcome from private individuals who own their own home and reside in properties located within England, Wales, Northern Ireland or Scotland (excluding the Isle of Man and the Channel Islands).
To be eligible for a grant you must have received a grant offer letter before work starts on your installation.
How will the application process work?
Applications are accepted on a rolling first-come-first-served basis. An outline of the process is as follows:
1. Complete the energy efficiency measures required by the programme. This is to ensure energy use
is minimised prior to installing a microgeneration technology to enable the most efficient use of the
technology. For more details on the required energy efficiency measures please click here.
2. Obtain planning permission for your installation if necessary or contact your Local Planning Authority
to ensure that the installation is classed as a permitted development. Please click here for details on
planning permission.
3. Obtain a quote from a certified installer, ensuring that a certified product will be used. Please click
here for details on certified installers and products.
4. Make an application online. By applying online you will get an instant response to your request.
5. After receiving a grant offer letter via email, contact your installer to confirm that they are able to begin
installing the technology. The grant validity period varies by technology, please see the table below.
6. After you have completed the installation and you have paid your installer, you should submit your
grant claim documents to the Energy Saving Trust.
7. The grant claim will be checked within 25 working days of receipt of all the documentation and, if in
order, the grant will be paid to you.
