Many thanks for the confirmation, I did ask him to put a 20 amp MCB in instead but he was adamant that there was nothing wrong with using a 32 amp MCB & when asked about the cable running in conduit he said those are guidelines only & not rules.No it shouldn't be on a 32A protective device.

Also because not all of the run was in conduit these "guidelines" do not apply.

He is incorrect. We cannot pick and choose which regulations we want to comply with or not. The cable rating for 4mm2 in conduit is at best 30 amps. If grouping is also a factor then it's even less.He is incorrect.

So a 20 or 25 amp MCB is needed.
