Effective date: 1 January 2023

What changes?

Does your company (or do you) work with boilers or gas-driven hot water tanks? Or do you handle plumbing for air supply or fume removal? From 1 April 2022 you will need to be certified to install or maintain gas appliances or pipes. If you do not have a valid certificate as of 1 April 2022 you are no longer allowed to perform these activities. This is then considered an offence. This legal obligation is introduced to prevent accidents with carbon monoxide.

For whom?

  • Installation agencies
  • (Self-employed) installation technicians


Installers need a valid certificate from 1 January 2023.
