The cable is fine (assuming you don't need high-smoke).

It is odd that the electrician thinks you sourcing items will be cheaper.

I see two main possibilities.

1. The electrican is a sole trader trying to stay below the VAT threshold, it's easy to do this if you are just selling your labour, much harder if you are also buying and reselling materials.
2. The electrican does most of their work as a subby and doesn't want to get involved in the materials supply game.

While valid points as to why he does not want to be suppling materials, just telling the customer to get it in would generally result in a complete farce of stuff missing, stuff wrong, and stuff thats the cheapest brand possible.

It's best handled by communicating the list of what is required to the wholesaler, confirming that appropiate pricing will be used, and telling them that the customer will be comming along with their credit card to pay for them, and either picking them up, or leaving them to be picked and so you just have to swing by on the way there to pick up a box thats all been paid for and picked.

LSF cable is likely to be used in schools alright, although T&E type cable isn't. Singles in galvanised containment is the norm in schools.

I think your out of touch there, pics from a new school building 2017:

I see the brown and blue cores are stranded, which suggests to me larger than 2.5mm2...?

2.5mm stranded is available, but in the pic it does look like 4mm in comparison to the CPC

In which case your advice is irrelevant/inappropriate again

So popped my glasses on and looked at the cable, ran some muck round it and numbers appeared, its 4mm grrrr.
My swapsy has gone wrong .

4mm

You were correct

 

[sparkwright]

It can be used, but I suspect your electrician will have a moan about having to connect sockets with 4mm2 LSF.

There's no reason it cant be used in place of 2.5mm² as long as your electrician is happy to use it.

Thanks all , I'll have a chat with him later, if you guys think it's alright I'm sure he will.
It's going on a 16a mcb that's rcd protected too.
