The Importance of a Gas Registered Engineer Gas Safe registration is required in the UK for plumbers and engineers who work with gas. This is important because carbon monoxide poisoning, defective central heating systems, and boiler installations kill many people each year. Engineers must prove their qualifications and competency to be Gas Safe registered. To do this engineers must pass tests. If they pass the test, they will receive the status of probationary registration.
