Edit: link didn't work
might be better to use something like these for the distribution circuits.
You suggested this one, but I am struggling to find anything bigger than a 32A.
I have found a 50A Single pole in India Hager Site but nothing on the UK Hager site.
I don't think you will find a 1 module carrier over 32A. realistically do you think you need to provide 50A to each office?
you will find it easier with regards to metering with 32A distribution circuits IMO as that's what most 1module din rail mounted KWH meters are rated to. just my opinion...
Only concern I have is they will be running 5 Double sockets, 1 Heater (1.5KW) and a 40W LED Lamp.
I dont think the load will exceed 32A but it might get close if they have a kettle & heater on at the same time.
how many computers per office?
Not big enough? The second link is a 24way TPN, that gives 72SP ways!Thanks but neither will be big enough, theres 40 offices, so needs to be 16 or 18 way TP&N
I was looking at the Hager or Havells 18Way DB, just need to find a suitable fuse carrier.
Does anyone have any concern about a 32A BS88 not being big enough for the demand? The calculations say it should be fine.
So calculate the design load of the submain and take it from there,Only concern I have is they will be running 5 Double sockets, 1 Heater (1.5KW) and a 40W LED Lamp.

They were only examples of what is available out there, its up to you to specify the exact product you need.
You are very unlikely to get a single board capable of fulfilling all your requirements here, much better to have a board for the distribution circuits and another for the final circuits.I didnt want to go down the route of a Reyley Board because this DB will also supply lighting and Sockets to the hallways and the toilets.

I thought this kind of basic design was still taught as part of an apprenticeship?
Theres 2 types of office.
Office 1: 1 Computer, 1 Heater (1KW) and lights. Total of 5 D Sockets
Size: 3m x 2.5m
Office 2: 2 Computers, 1 Heater (1.5KW) and lights. Total of 8 D Sockets
Size: 3m x 5m
You're buggered then of the pricing of the job is being done backwards, you wont be able to deliver a safe amd compliant installation.The other problem I have is the budget. It wont facilitate a £1,000 DB Board!

Design should be done first, then quotes submitted based on the approved design. Not the price set and then the design bodged to fit it.
