I know this is a late post, but it may do someone some good - or at least upset the ivory towers.
Let's get something straight from someone grossly overqualified with a scientific background - (yeah, it does sound like I'm conceited, but there are those from whom I have had 'expert lectures, with Phd's, professors and Consultants in ALL fields, who weren't fit to wash my feet. I attach no importance to my professional qualifications as a result. Stick that in your ivory towers (No uni's mentioned)), The NIC and disbanded CORGI are only bodies of people who have been dealing with this stuff for a long time, or a concentrated time. No rocket science involved - I was CORGI registered until a short time ago, and got disgusted when they resized vents in the boiler cupboard twice. If you're looking for a safety margin, why not go the whole hog, stupid!
Before this, the NICEIC decided that my shower pullchord no longer needed to be 1.2M away from me in the shower - despite the fact I had always contended that the Bathroom door would be locked anyway.
These are but two minor points.
Of course we need a body of common sense, of course we need Health and Safety, but there are those whose reason is clouded by arrogance, greed and social ladder climbing, and those who feel a need to support those above them. (There is a name for this). The gasman has one advantage. He has a manometer which measures millibars - he puts it on the supply pipe, and if the pressure drops in a certain time, he knows you have a leak.
Fittings and pipework is reasonably tested, surprisingly enough, with soapy water. PTFE tape is the best sealant for joints to date.
I have seen poor jobs on soldering, boss white, and whole installations by CORGI registered installers - I have had a 16th edition qualified electrician NOT understand the principle of ELCB's.
So don't let's play pious - I advocate the thorough examination and questioning of an installation by the owner never mind the installer - they aren't always to be trusted
Remember your science lessons - double check for leaks, do the job right from the start, and if it doesn't feel right - recheck or re do. Switch all appliances off and watch the gasmeter over a couple of hours, see if the reading increases.
My concern for qualifications has always been the examiner - just as you get people who have no clue how to drive who have passed their 'test' - you know in your heart, the examiner was, at the very least, mistaken.
If you don't feel confident, don't do it - if you do, be prepared to question yourself.

listen here pal. we dont make the rules up we are just telling u the
law
you are not allowed by
law to fit a gas appliance unless you are competent person, ie passed ccn1 in gas.
sorry but that is how it is mate
You see you have now lost all credibility in my eyes because I know that isnt true. It is for people doing it for a living but not if diying at home. The law requires them to be competent but not to have a particular qualification.
If a job needs tests that a diyer cant do with test equipment he doesnt have then explain that and people will go away happy that they have had good advice but the kneejerk answer of "if it says gas anywhere you must use a gas fitter" and then rubbish like that about the law only looks like youre trying to hoodwink people and then theyll go away thinking that theyve had crap advice.
What are the more likely to follow? What they see as good advice or what they see as crap? If you really wanted to help people youd give them useful advice they could trust not tell them the law says things it doesnt and make them think they cant trust you.
