Individuals who carry out works and who are not registered will be subject to criminal proceedings.


To be eligible to join the Register you must show proof of training and qualifications. (level 6 advanced craft certificate in Gas Fitting, Electrical, Plumbing or Refrigeration or equivalent).

Trainees/apprentices must also register but applicants must show evidence of education/training achieved to date and must also be in a position to nominate a supervisor(s) who will take responsibility for supervising work and signing off completion certificates issued by the trainee.
