A letting agent has asked for a second opinion on a CU, Apparently the elderly and long term tenant passed April 2020 with covid, they took the opportunity to do some refurb including new CU and some rewiring and cert issued at the time shows an existing submain to shed on 25A MCB. and existing shed CU as 4 MCB circuits for: Outside DSSO - 16A, internal DSSO - 16A, light - 5A & pond pump - 5A.

Tenant moved out recently so EICR done and only shows one code which is shed CU C1 need replacing and quote for £600. From Agents description it sounds like it may be a metal Wylex with plug in MCB's.

Yes I know it's old and I haven't seen it yet so don't have any condition report, do any have a real opinion on the continued use of them or should they be replaced regardless? (I have 2 bakelite versions in use at home:notworthy:)

I'm assuming there is RCD there somewhere, else it shouldn't have passed 3 years back.

Nothing wrong with those plug in MCBs other than the lack of RCD protection.
If there is an RCD / RCBO for the shed submain, no separate RCD required in the shed.

For only 2 sockets, light and a pump, the shed doesn't really need a CU of it's own at all. Wire the sockets direct to the submain and add a couple of FCUs for the lights and pond pump.

In any event, nothing there that could justify a C1.
C2 if no RCD protection or some other unmentioned problem.
More than likely no code required.

That just about sums up my thoughts but I won't be there till next week to see what's what.
 
My thoughts have always been C1 is simple, you can touch some thing live. So missing base for plug in MCB's yes C1, but there needs to be some thing rather drastic to warrant a C1.

If no reason for a C1 then clearly an error so original EICR is void.

Nearly everything we give a C2 to, could also be given a C3, the potentially dangerous label is pointless, as all 230 volt is always potentially dangerous, so it is at the inspectors discretion as to what has a C2 and what has a C3, missing some thing yes trading standards can and have pulled inspectors up on it, but as long as the items are listed, and it would have passed when designed, then no one can really say the report is in error.

I feel all domestic premises should have all circuits with RCD protection, but unless TT this is secondary protection, so it is only recommended. With a TT then yes C2 or even C1, but not with TN, however this is a personal opinion, there is no rule either way.

@SUNRAY What did you find when you went to the site? What reg(s) did the EICR refer to when the inspector coded C1?

Blimey, can't believe this is a month already, still waiting for access, not sure what the hold up is as I'm going as a second person and a 'subby'.
 
WOW. that started over 2 months ago, apparently the tenancy agreement came to an end, the agent attended and completed paperwork/took possession of keys etc, electrician attended later that day for EICR then the tenant moved back in and claimed never moved out; AAAaarrgh!!

We are now expecting to get in early next week. In the meantime; part of the estimate for correcting the CI came via email including an apology the scan has cocked up formatting:

That's a steep estimate for a shed CU with 4 circuits and you still haven't said why the current fuse box has a C1 code. As already pointed out, the shed doesn't necessarily need a CU. In your first post you said there were 2 5amp fuses and 2 16amp breakers, but the quote has a 32amp rcbo. If this should be a 16amp rcbo, there is no need to change the main board.
