If in doubt call an engineer.
Oh by the way, the worst ones for leaking are the awkward rigid connections on gas cooker hobs. The connections are so awkward tucked away in the corner recess of the hob that they are are a swine to tighten up and there's loads of leaks found on those connections.

I do a regular and rough pressure drop test on my caravan and home. Turn everything off, then isolate the gas then leave it isolated for a few hours without turning anything on. When you reopen the isolating valve slowly listen carefully, there should be no hiss. The hiss indicates that pressure has been lost so there is some leak on the system somewhere.
It is not a replacement for a qualified gas engineer, but is a check which can be made quickly and easily.
