Will fused box Without RCD fail the EICR for Rented Property?

If you've had any recent alterations to the wiring you may pick up a C2 due to lack of RCD. If its original wiring with any alterations done prior to manadtory RCD protection then it's a C3 rating. No way C1.

I have found loads with fuseboards that have been satisfactory. I would find another electrician to be honest if only for a 2nd opinion. I think he may be using scare tactics as a way to generate work for himself. Have not seen it but this is not a C1 on an EICR.

I'll be short and sweet - no it's not a C1. More a C2. Potential to be a C3. C1/C2 both result in a unsatisfactory result anyway. It would be more a combination of issues ie no rcd on circuits feeding a bathroom AND no cross bonding in place. C1 is akin to a live wire hanging out the wall (immediately dangerous) C2 is dangerous in the event of a fault (no earth to a metal light) C3 - not to current regulations plus a lot more. Its hard to tell without seeing and giving a calculated answer. They could also be a 6WW (6 week wonder) where they have done a 6 week course and call themselves electricians - with no real life experience - the worst type of electrician...... Check if they have professional indemnity insurance which covers their opinion. If they do not have this then be aware that they are not covered to give their opinion of their interpretation of the regs. Big no no if it was to go wrong.....

Basically if you can plug something into a socket and take it outside ie lawnmower then it’s a c1 No bonding in bathroom on bath and taps c1
