Is the EII scheme auditable….and if so by who?

The EII scheme is managed by the BEIS (Department for Business, Energy and Industrial Strategy). BEIS will monitor applications and it reserves the right to undertake further validation or investigation, if deemed necessary, before issuing a certificate.

They have also indicated that there will be a random check made of a sample of applications.  Their current plans are that this will be done by a BEIS official but they may also use an independent verifier.
