If you do it right, no one will ever know. If you do it really wrong and
there is big bang they will, but they aren't going to be bothered about
ascertain your competence at that point.

The problem is, if a house caught fire / exploded .... and you had
worked on the gas, and you hold no formal gas qualifications ... be
pretty difficult to prove competency.

As the PP said, there is no legal definition of competence in this
context. Holding 'formal gas qualifications' *might* meet a legal
definition, if that was ever tested in court. At present, that doesn't
seem to be the case.

Remember, we are answering the OP's question about DIY-ing on his own
gas installation, which is a different issue to that of paid-for work.
