Illegal Gas Fitters Convicted: HSE Warning
14 Sep
Summary
- Seventeen individuals convicted for illegal gas work since 2025.
- Unregistered tradespeople pose risks of leaks, explosions, and CO poisoning.
- Check engineer's Gas Safe Register status before hiring for safety.

The Health and Safety Executive (HSE) has reported a sharp increase in convictions for illegal gas fitting. Since the start of 2025, 17 individuals have been convicted for performing gas work without the necessary accreditation, a notable rise from previous years. This trend underscores the dangers associated with employing unregistered tradespeople for gas appliance services.
Improperly installed or serviced gas appliances, such as boilers, cookers, and fires, can have catastrophic consequences. These include gas leaks, explosions, fires, and potentially fatal carbon monoxide poisoning. With colder temperatures increasing the reliance on heating systems, the HSE emphasizes the critical importance of hiring Gas Safe registered professionals.
As part of the annual Gas Safety Week, the HSE issued a strong advisory: always check if your gas engineer is listed on the Gas Safe Register. Hiring unregistered individuals to work on gas appliances is a serious risk that could lead to life-threatening incidents. The public is urged to refuse entry to any engineer who cannot provide their registration details.
