The Gas Safe Register is the official gas registration body of gas businesses and engineers in the United Kingdom. By law, all gas businesses and their engineers must be on the Gas Safe Register to work legally on gas equipment downstream of the meter, therefore QHS is a Gas Safe Registered business.

A gas engineer can only be affiliated to a registered business and be issued with a license to undertake gas work on behalf of a registered business if they hold a valid and current qualification. This evidence of competence relates only to matters of gas safety and is obtained by every engineer through a recognised route of training and assessment, such as the Accredited Certification Scheme for Gas.
