It is unusually to have ceiling below 2.25 meters high (Zone 2) but where they are than IPXXB or IP2X for plus IPX4 or if exposed to water jets, e.g. for cleaning purposes, IPX5 is limiting factor as well of course as having an RCD.
XXB = Protected against access with a finger (minimum 12 mm diameter test finger, 80 mm long) (adequate clearance from live parts).
2X = (a) Protection against access to hazardous parts with a finger
(b) Protection against solid foreign objects of 12.5 mm diameter and greater.
IPX4 = Protected against water splashing from any direction
IPX5 = Protected against water jets from any direction
So either IP24 or IP25 in real terms you can forget about the IP2X as if to IPX4/5 it will be better than IP2X.
There are loads of lamps that comply with this just go to local whole sale outlet.
There is no such thing as a Part P consumer unit. There are consumer units which can easy be configured to BS7671:2008 which will normally have at least two RCD's and bathroom lights will now be covered by an RCD.
