Hmm. Just noticed an extra part of your reply - didn't notice it last night, and suspect that you added it while I was composing my response. Anyway...

But note this was the law in 2003 when this was printed. New gas LAWS came into effect this year.
You refer to some relationship between a law being printed and being in force. There is no such relationship.
So, I continue to be unware of what you colloquially call "new gas laws" coming into effect this year, unless you're referring to the new changes to the Building Regulations 2000. I note that SI 2004:3210, regulation 3(5), states:
In relation to building work of a description within the first 3 heads of column 1 of Schedule 2A (installation of a heat-producing gas appliance, of an oil-fired combustion appliance or oil storage tanks and pipes, or of a solid fuel burning combustion appliance) where the contract for the provision of the work is entered into before 1st April 2005 and the work is completed before 1st July 2005, the principal Regulations shall continue to apply to that building work as if the amendments made by regulation 2( 8 ) had not been made.
My interpretation of all that is that, where SI 2000:2531 permitted installation of a gas boiler to be performed by a CORGI installer,
without notifying the LABC, they must now notify in the way that non-CORGI installers always had to, although there is a caveat based on time to allow (I surmise) work in progress to be completed.
I don't know whether or not this supports any of the points that you've been trying to make, because they've all been so garbled. If it does, then so be it; the point I would make is that these changes to the Building Regulations are not contradicted by anything I've posted on this topic.
It might be that you don't realise that guidance notes, and explanatory notes, published by the ODPM, are not law, and that some of them are even wrong with respect to the law. For this reason I don't rely on them, don't refer to them, and don't quote from them.
