Need a new consumer unit for approx three ring mains and two lighting circuits (kitchen/extension and cooker already on a fairly new one, no immersion heater).
One-man-band professional electrician coming round to quote at the weekend. What should I reasonably be expecting?
Got my 7 way replaced with a 14 way Hager CU with 8 RCBOs and SPD (a quality unit hence by no means the cheapest, parts cost £200-300), quotes were about £650-800. Due to scheduling constraints I went with the £800.
It's roughly a half a day job so work out your hourly rate. Parts costs upwards of £100 depending on what you want (RCDs, RCBOs, SPD, AFDDs*, etc etc).
Metal clad consumer unit, 5x RCBO , and probably an upfront, or, consumer unit integrated SPD, full test on completion, Install Certificate and Part P notification should be included. I would have SPD fitment if it was my house. £600 would be about right. £500 is possible if a cheaper type of no-name consumer unit is used, or standard circuit breakers with 2 x RCDs used. e.g. Fusebox' RCBOs are £12, Wylex are £32.
Yup, the subtext here is expect to uncover a few additional bits that might need fixing...
Equipotential bonding might not be up to scratch. Circuits might not text successfully (ring continuity etc), requiring extra investigation. There might be shared neutrals between circuits (will cause RCD trip), or circuits might fail insulation resistance checks.
Precisely. There's a lot to be said for letting sleeping dogs lie as far as existing circuits are concerned, and installing a new CU to current regs for any additional circuits.

Neither the installation for the new kitchen/extension, nor the smart meter, qualify for that.
Yes, the installation comprising the two old fuseboxes does, which is why I want them replacing, Dear Liza.
Part of me wants him to upgrade the tails (quite short) between the main fuse, the Smart Meter and the consumer unit backboard, with better than the 60A ones currently in place, so I can get the main fuse upgraded.
But on balance, I think it might just confuse the situation.
I get this a lot when talking to eg professionals in HR, IT, the law, that if you ask two, three, four or five questions at the same time, they only answer the easiest, and ignore the rest.
I'm about to send off a request to an IT department regarding three separate (but interlinked) tasks, and which would be *vastly* more efficient for them to do all three at the same time. But I have this sense of foreboding they'll just pick the easiest and ignore the other two.
So maybe they'll get a series of them, instead.
[Recursively, I asked the guy doing the electrics for the new extension to quote separately for doing this latest project, and despite several reminders - and not even needing to do a special site survey as he was already here - just ignored it. I suppose someone will now claim that's evidence it's "too difficult" work, rather than "I'm already fully booked till the end of the year"; which isn't true because I know for a fact these guys moonlight at weekends].
Well yes, but investigation takes time. Most electricians don't want "if then maybe" jobs they want predictable work so they can schedule the next. I think most will want to re-wire. If you have shared neutrals, for example between upstairs and downstairs lights how on earth can any one find that? It could be in any junction box. In my case it was linked smoke detectors that caused issues. Upstairs on on upstairs lights, downstairs one on downstairs lights. Linked by wire it was enough to trip the RCD/ELCB. Took me ages to find, and then get Sparks back to finish job.
Later when the kitchen was re-fitted we had issues with broken rings. Again a pig to find, you probably need to remove every socket.
No checks will have been done for Smart Meter. They just swap the meter. So you didn't get an EICR when you bought?
