EICR Certificate - Should Bathroom light not having RCD protection be C2 or C3?

AdamG

Hello,

Is anyone able to please clarify?  An electrician has just undertaken an inspection to allow an EICR to be issued.  They have stated there is a requirement to have RCD protection for the bathroom light (given it a code C2) and so they are quoting £600 to fit a new consumer unit.  I appreciate that if the house was being built today that it would need to comply with the 18th edition regs which came into force in Jan 2019 and hence would indeed need an RCD on the bathroom light but my house was built in 1956 although has a 16th edition CU with RCDs on socket circuits only but I thought this should be coded as a C3.  Any advice greatly appreciated.

Thanks

    Adam, is this a rented property? Much the easiest fix is the RCBO you have bought in a matching box (from Screwfix) in the lighting cable at any point outside the bathroom. This will then be fully compliant and removes all your difficulties. The batten holder you mention will also have to be changed unless more than 2.4 metres above/away from the bath for one that is at least IP44 and preferably class 2, which is not difficult to find. What is the light switch and where is it? This also needs to be outside of possible contact, ie: outside if a standard switch or a cord switch if inside. Doing these things will not take very long and will be much cheaper than your new CU quote, which may itself turn up other problems. You should document the position of this sub-board near the CU, if it is not obvious, and label it “Lighting RCD / CPD”.
