If you wish to check that an energy assessor is a member of an accreditation scheme, you can do this in two ways:

  1. verify the credentials of your energy assessor online via which provides a national register of accredited energy assessors. This will allow you to search by the energy assessor’s name or accreditation scheme membership number
  2. ask your energy assessor which accreditation scheme he/she is a member of (and his/her membership number). The accreditation scheme can confirm that your energy assessor is accredited to practise as a DEC energy assessor for your particular type of building
