Who is qualified to issue a Gas Safety Certificate in London?

Only engineers listed on the official Gas Safe Register can carry out gas safety checks and issue valid CP12 certificates. Always check the engineer’s ID to ensure their registration is active.

What happens if I don’t have a valid Gas Safety Certificate in London?

Failing to provide a valid Gas Safety Certificate can lead to severe penalties, including fines, prosecution, and even imprisonment for landlords. It may also void your property insurance and put lives at risk due to potential gas leaks or carbon monoxide exposure.
