joining two feeds into one consumer unit.

Seperate consumer units then.

Or a 3 phase consumer unit

Your electrician would be better buying the equipment. Then he is responsible for. He will also probably not offer any warranty on items you have bought yourself.

He can also likely obtain it considerably cheaper than the OP can.

Good idea, I can just use two phases and somewhere for the third to be terminated.

You clearly have no understanding of a triple-pole (three phase) distribution board and the requirements for its supply. It maybe possible to utilise the existing cables but they need to terminated in an appropriate manner and not something you should consider doing yourself it is way beyond your scope of ability. You say you have an electrician so I suggest get them involved to assess what you have and how best to proceed.

Just had meeting with Electrician and all is well. Thanks for all your input.

Let us know what his plan is.

The dno will feed into a new meter box in the garage, this will feed a 3 phase distribution board.
From this:
Phase 1 will be connected to the house cu via existing swa.
Phase 2 will be connected to the existing garage cu.
A 25mm swa will feed the new workshop distribution board that will feed all the switched 3 phase plug sockets via 3x3 galvanized trunking and a ring main + lighting on phase 3.

My existing solar inverters will remain connected connect to phase 1 via existing swa to house cu.

I believe that I may be able to retain my house meter for reference so I can allocate the electricity cost proportionally between business and private.

One thing that may help me for neatness ( and yet to be discussed with electrician ). I would like to fix my metal clad sockets to the galvanized trunking and feed them from the back of the socket. I'd also like to do this with the 16A + 32A switched 3 phase sockets, I suspect they will be too big though. Any tips welcome.

Thanks

Greg.

Wait and see what your electrician intends to do, you are giving the impression that you are doing it yourself, so at least please do not fit all your accessories to the trunking lid.

Sounds like your electrician has the info he needs and can plan the install then. Dont worry about the fitting of sockets, he'll know how to do that.
