Current unit is a MEM Memera 2000 with 7 connections - mix of fuses and
RCD.
To supply and install a new 18th edition consumer unit, replacing the existing dated fuse board. The new board will be metal clad and
incorporate RCBO's in order to apply the required RCD protection. The
main supply tails and earthing conductor will also be upgraded. A surge protective device (SPD) will also be installed. Clear and formal circuit identification will be applied. All supply cables entering DB-1 will be adequately supported and containment will be installed The new DB will
be installed and fully comply with wiring regulation BS7671.
This cost is based on the existing bonding being suitably sized.
We have also allowed to test the system upon completion but please be
aware that should there be any issues identified that prevent
certification to be completed, these would need to be rectified
additionally prior to certification being issued.
£695 + VAT = £834
***********
The electrician is the one the plumber used to wire up the new
controller and he made a very neat job of that.
Does that seem to fit the bill?
Should I specify a make (or choice of makes) for the consumer unit to
ensure it is a decent one?
Now my new boiler is up and running I want to have my consumer unit
replaced. Much as I would like to DIY it is beyond my physical abilities
and in any event needs to be certified. I have a quote as follows:

Well if using decent quality parts and assuming he means all circuits
are RCBO protected, then £250 of that is materials... (based on a quick pricing assuming 8 circuits in a 10 way Hager CU)
So all RCBO is good - better discrimination under fault conditions, and
less risk of nuisance RCD trips.
I expect he has factored in some time to allow for fixing existent
faults that may not be apparent at the moment (like borrowed neutrals etc).
Should I specify a make (or choice of makes) for the consumer unit to
ensure it is a decent one?
Might be worth enquiring what he would use...

Good question! If a fuse goes in the current unit it is a PITA to
replace
Aside from not being shiny and new, what is wrong with the current setup?+1 !!!
He already has RCD protection, though it sounds as if there is only
a single RCD. This is a 1983 property. What Wiring regs were in force
then ?
Because he seems to have a lot of computer stuff over and above an
average person, a single RCD installation might be tempting fate.

The only time any of my Wylex rewireble fuses ever 'went' was after
someone (cough) shorted something out. Ouch.

It is one RCD (or whatever they are called now) per circuit, it's just
part of keeping things up to date.

I have known incandescents take out fuses and MCBs, but not known such

If I were to redo my CU today I would fit RCBOs to all 13A outlets and a
main RCD of around 100mA to the whole box
and use a brand that I knew would be around for as long as MK has.

They have said they would fit a "Fusebox consumer unit", does that sound OK?
It's a budget brand, been going since 2017: https://consumerunitworld.co.uk/fusebox-389-c.asp
Sounds ok, in that the budget brands are still held to the same standards as everyone else so they should work as expected. The one question with budget brands is whether they're going to be around in years to come when you need to add extra circuits or otherwise modify the installation.
In theory you are only supposed to use components that the manufacturer has specified will work together, which means sticking will all one brand. eg there can be issues fitting busbars from one brand into the terminals of another. Not something that can't be worked around (worst case you could just use a wire), but less than ideal.
My CU replacement in 2021 was a similar scale job and similar price to yours, but that included using Hager components. They had suggested Fusebox
but I asked them to upgrade as I may put in further circuits in future. OTOH there's been inflation since then, which maybe covers the difference.

I think this is sound advice.

main RCD of around 100mA to the whole box and use a brand that I knew
would be around for as long as MK has. And leave some extra places for expansion.
Even if it cost another couple of hundred.

Are you a TT supply? I though not with your mention of replacement transformers etc ... why add a single point of potential nuisance trips?
and use a brand that I knew would be around for as long as MK has.
Are MK that safe nowadays? They announced in 2019 they were stopping
doing CUs, then changed their mind.
Look in the footer of <https://mksentrycircuitprotection.co.uk>
The MK brand is owned by Novar ED&S, in turn by Novar Holdings, who are
in liquidation, the head office is Honeywell House, which reflects the previous owner, the UK factory at St Asaph is gone, now made in China by Yihua ...

But would have thought they'd do an EICR beforehand so that they know
the state of ring continuity, insulation resistance, supply earth
impedance, missing earth on old lighting circuits, borrowed neutrals,
etc otherwise they could end up finding issues after the new board is
fitted ...

Except there really is no need for the main 100mA RCD and it would serve
no purpose apart from creating nuisance tripping.
If the supply had very long tails then perhaps I can perhaps understand
the 100mA RCD closer to the supply but it should then be one with a time delay for discrimination.

Apologies for coming back on this but I thought somebody had mentioned
good quality manufacturers, including Hager, but I can't find the post now.
Any recommendations please?
