thing is mate;
there will be the group that go to the niceic registration and become legal, with this a price will have to be passed on to the coustemer.

then you will have band two, made of people who have their city and guilds,  and dont see why there should be their extra cost, so will keep going as they are.

personly, i stand between the two
i have C+Gs
ill keep going as i am
ive got to go and do the test and inspection course
and then get registered, i will do it eventualy, if somone comes along and actuly somhow enforces it then i have a mate who is getting registered and ill just stick say £150 on top of my bill for the test to be done.

its not enforcable however so bugger em, they know where they can shove it

i also doubt that the landlord who i do the maintenance for will care either
