Will a consumer unit upgrade give me correct RCD protection for Bathroom

The current downlights haven't the correct IP rating and the fan is not 12v, (the fan and 2 lights are very definitely in zone 1) the plan is to swap out for ones that are ... I was advised that this constituted added "new work"
IP rating is a separate matter.
Fans do not have to be 12V - 230V is fine as long as suitable for the location.

Replacement of appliances is not new work.
 
Regardless of what the regulations force you to do, it it still a good idea to add RCD protection to your installation where it does not currently exist.
 
so as long as i replace the fan with an ipx4 rated model and use the correct downlights in the original locations I'm okay?, i'll probably still change the CU it just means it can wait a few months as cash is tight ....
 
I'm not doing anything myself I'm going to use a registered sparks, i'm simply trying to establish what the regs are ..I'll book a registered electrician for all work whether a I need to change the CU first or not ....
 
While I'm on is there any such thing as an ip65 rated pull cord switch?
 
because after the new shower screen goes in, the existing pull light will be in zone 2 and if possible I'd rather not have to move it ... and yes the ceiling is lower than 2.25 meters .by about 10cms
 
Where exactly is it?

The other side of the shower screen is likely NOT in zone 2. Zone 2 will be measured 600mm. from the open end of the screen; not its corner with the wall.

Nearly all the diagrams on the internet are wrong.

Zone 1 should be in the shower enclosure.
 
cheers fella ...in that case i'm okay, when the screen is fitted there will be a 40-50mm gap to the ceiling. The switch is 50mm from the edge of that gap with screen on the ceiling which i thought made it zone 2 what with the ceiling height being so low
