What has changed?
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? You need to be certified to install or maintain gas appliances or pipes. If you do not have a valid CO certificate of proficiency (CO-certificering), 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.
CO-free certified companies have the CO-VRIJ logo (CO-free logo) and can be found in the gas combustion plants register (in Dutch).
- installation agencies
- (self-employed) installation technicians
Installers need a valid CO certificate from 1 April 2023.
