Self-obsessed?
You lot? Well possibly - since the debate has gone on for many pages.
But this (well - at least Plumbing & Heating, where this started) is a DIY forum, ostensibly where people who have reached a 'DIY frontier' can maybe get some sort of answer that resolves a specific problem. Unfortunately, and especially in the context of gas, that will often be 'Get Someone In'. This is for two reasons: first because it's the only LEGAL thing to do, and second because anyone who is qualified to give any advice at all would risk their CORGI registration by saying anything different.
So the answer may not be what you want to hear. But why should it not be short and to the point? It's DIY, not PC Debating 101!
