I've done a smidge of gas work, and it's not gone wrong. I made sure it
wouldn't by testing it - I didn't want to just guess.

As I said to Peter, this stuff isn't magic. It's not that hard to do
appropriate testing to demonstrate that it's not going to go wrong as a
result of what you've done.

Also disagree with logic "Ultimately, when doing work for yourself, the
person that you need to convince of competence is yourself " at some
point someone else may own that house and therefore your work is then no
longer for yourself.

Their problem. When buying a house you take on all the crap which comes
with it - and get professional advice if you're worried.

Your standards don't count .... it's what is the accepted standards ...
eg GasSafe & Corgi registrtaion.

It appears that the certification isn't required on selling a house, ie
it doesn't matter whose standards one is using.
