MCS are administering the Standard for the scheme, and HETAS is committed to operate the scheme in accordance to the standard. Any complaints related to the scheme from a member of the public, will be assessed fairly. 

HETAS will report scheme data into MCS, Ofgem and BEIS to ensure that we all understand the success of the scheme and where we can make improvements for all users.
