Why should they? There is no requirement to use metal.

Indeed - and, in any event, I'm not sure that a standalone isolator switch necessarily qualifies as a "consumer unit or similar switchgear assembly", does it?
I've also just noticed the seemingly rather strange wording of the second note to 421.1.201, which says:
Apart from being a bit of a grammatical mess, what on earth does the second bit of that mean? It seems to almost imply that non-combustible CUs were not permitted prior to the appearance of this new regulation!
Kind Regards, John
It means you can comply earlier if you want.
It means you may fit (and comply with the new regulation) before 2016.

I would have thought that an isolator was a switchgear assembly.
And it has plenty of current flowing through it to create plenty of heat.
I know that's what it says, but why is it saying it? Wasn't it equally permissible to fit a non-combustible CU in 2012 or 2007, or .... ? What has the new regulation (or the period between 5th Jan 2015 and 1st Jan 2016) got to do with this?

I don't really know what they intend. If you (and your criteria) are correct, then where does one stop - do you include standalone RCDs, shower isolators, cooker control units, switch fuses ..... ??
Kind Regards, John
Well certainly shower rcd/MCB units.
They want to encourage fitment ASAP rather than wait a year.
For safety, customer satisfaction and to get ppl used to them.

But some 'electricians' tell people that their rewirable fuse box is illegal and must be replaced.
It is to save them having to come back next year when their '17th edition' CU would become illegal because, obviously, two versions cannot be legal at the same time unless explicitly stated.
OK, it means you can claim compliance with the Amendment before it comes into force.
Not according to the definition in 61439 it isn't.

At the start of the lecture he held up both old and new regs and said any new installation can until June be designed to either set but you can't mix and match.
I did wonder what in the new is not permitted with the old?

Not sure. Perhaps he was just reinforcing the old point that you can indeed work to one or the other (before the changeover date) but not cherry pick from both.
I doubt that many would disagree with that - since it's "similar to a CU". ... but what about shower/cooker switches/isolators etc?
I must say that I wouldn't read it as particularly 'encouraging' me to do that. It is merely telling me that I am 'allowed' to do something during this year which I have, in fact, been allowed to do for decades!
Kind Regards, John
You haven't actually been able to comply with Amendment 3 until recently.
You could have fitted a CU in a non-combustible enclosure, but you couldn't claim compliance with the Amendment on the certificate.
