My original plan was to have 2 ring mains in the kitchen - one NOT protected
by the RCD which would carry just 4 things - the CH boiler, the fridge, the
freezer and the oven (which needs a 13A supply). The other ring would carry
everything else - kettle, washing machine, toaster, telly, etc., etc.

The guy has dropped a b*****k and made the NON-protected circuit a radial,
feeding just the boiler, the fridge and the freezer. He's used 2.5mm cable
and I know that as long as the MCB is 20A rated, that, in itself, is OK. The
oven is now on the protected circuit and I know that that circuit - even
given the extra loading of the oven - is, in itself, OK.

But it's not what I planned and it's not what I asked for.

To put it right would mean that he would need to use 4 junction boxes, which
would be under the floorboards in the bathroom - the same floorboards that
are going to be sheeted over with hardboard or thin ply before having vinyl
cushionfloor lain on top - in other words, not easy to get to them if needed
later on. OR, the other way to put it right would mean hacking chases in 3
of the kitchen walls - 2 of which have been newly plastered, the other newly
tiled (

So, should the oven be RCD-protected (leave things as they are) or not (get
him to put things right)??

just wondered why you planed the job and don't trust the electrician you
employed to do the work?
