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

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

More than likely should be a C3 but even if it did need RCD protection a RCBO would be a cheaper option or move the lighting circuit to the RCD side. Was this the only C2 code?
