How will we guard against fraud?

We have rigorous requirements and checks in place to make sure that we prevent fraud, described below. In the unlikely event of fraud being detected, we will report and prosecute.  

  • Installer checks: all vouchers submitted for a claim must include the installer’s accreditation/registration number. We may  check voucher claims against work recorded with the accrediting organisations. Any installations that are found not to be recorded with the relevant accrediting organisation will be further investigated and, where necessary, there will be a home visit to ensure the work has been completed.
  • Boiler checks: we will also visit a random sample of applicants/homes to check that all the requirements of the scheme are met. This will be either when we receive the application for the voucher, to check the current boiler, or after the claim for cashback has been made, to check that the boiler has been installed.
  • Property checks: we will check all applications to make sure we only give one voucher per property. Multiple applications for the same property will be investigated.
  • Accreditation checks: if you are a landlord we may check your accreditation, or that of your agent, with the accrediting organisations. 

We reserve the right to conduct other checks and monitoring procedures.

Overall the scheme could save each year:


  • KWH: a kilowatt hour is a unit of energy
  • NOX: oxide of nitrogen is an air pollutant
