The Application

  • Homeowner checks their eligibility on the Simple Energy Advice website. You’ll complete their online questionnaire to check which measures you are eligible to install. (*Please see note below for more detail on this.)
  • The homeowner finds a registered installer and gets a quote. An onsite survey by the proposed installer may be required, in order to give a realistic quote.
  • The homeowner fills out the application form and lodges the quote with the Scheme Administrator online.
  • The Administrator assesses the application and issues the voucher.

*NOTE: The government guidance is to get an EPC done for your property (or use an existing one if it’s not more than three years old) and get recommendations on top for the measures that are included in the Green Homes Grant scheme. The guidance also states that you should get independent advice from a source other than an installer. You will be required to tick a box on the application saying you have taken advice or are happy with your own investigations.

  • The name and date of birth of the property owner or owners
