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

    I can think of a possible scenario where RCD in a box might not be a good idea.

    homeowner gets occasional tripping from said RCD and fumbles in the dark to reset it. Decides to fit a light next to CU so its easier. Takes the feed from the input side of the RCD, either as a mistake or deliberately (so stays on when RCD tripped). If an RCBO had been fitted, all of the circuit would be protected
