Prevent carbon monoxide poisoning

To reduce the number of victims of carbon monoxide poisoning, new legislation came into effect on April 1, 2023: the legal CO system. From that date, only CO-free certified companies are allowed to perform work on a gas combustion system. Hiring a non-certified company or doing DIY work on a gas combustion plant is prohibited from that date.
Certified companies to be found in registry
CO-free certified companies can be recognized by the CO-free logo and can be found in the 'register of gas combustion plants'. An installer also carries (digital) credentials with him or her that show he or she is working for a certified company. Companies that are not in the register after April 1, 2023, may no longer perform work on gas combustion installations until they obtain CO-free certification.

Carbon monoxide poisoning
Carbon monoxide (CO) is a deadly gas. You can’t smell, taste, or see it, but people who breathe it in can suffer serious health problems and even die. Every year, carbon monoxide poisoning causes five to ten deaths and hundreds of hospitalizations. Carbon monoxide often enters a home through a gas-burning appliance that is not properly installed or maintained, such as a furnace, water heater, gas stove, gas fireplace, or flue. This was revealed by an investigation by the Dutch Safety Board (OvV). The new legislation was therefore enacted on the recommendation of the OvV.
