10mm may be needed, however 6mm may be suitable. Depends on how the cable is is installed.

True. However, if it were me, even if 6mm² were adequate for the present 9.3kW shower, I think I would probably use 10mm², in the name of 'future proofing', particularly if some of the cable was going to be buried beneath pretty tiles!

I would advise buying nothing, and having the electrician doing the wiring provide the cable.

Very commonly said.

A little while ago I was with a group of electricians, some of whom encourage their customers to provide materials, so I asked them "Why?". The answer, which I confess had never previously occurred to me, was that they wanted to keep their turnover below the VAT registration threshold, in order that they could offer competitive prices to their (almost all not VAT-registered) customers.

I wonder how common that is?

But what is your advice worth? Especially as you no nothing about the circumstances, so stop guessing wen you don't no.

Very common in my case, but for different reasons, most of my customers are VAT registered companies and I am not

I detest it when people buy materials for us to fit. We're pretty lucky in that it doesn't happen all that often, and my boss manages to talk them out of it most of the time (VAT registered company). The garbage you get handed is unreal. It's very likely LAP and awful. Or a B&Q light fitting that is downright impossible to fit

More than you can begin to comprehend.

The people I talked to certainly were not happy that they "had to do it", but said that being able to charge their (non-VAT-registered) customers nearly 17% less, for the same profit, was such an advantage they they had decided to accept all the downsides of letting customer's provide materials.

Having said that, they all said that, whenever possible, they told the customer exactly what they should buy.

So they remain competitive by making their customers pay more for materials than they need, and by being unable to reclaim VAT themselves on all of their business expenses?

An interesting business model.

Yea it can become tricky with warranty because you have to warranty your work, and if a customer supplies the materials, whose fault is it if a socket goes faulty?

Yes, it is an interesting model. They appear to believe, rightly or wrongly, that the increased business they get by 'being cheaper' more than offsets the fact that they cannot reclaim VAT.

If you want to argue about this, I am not the person you need to argue with - I am just the messenger.
