I don't think anybody knows for sure, but based on the info on the 'Design studio' page:
- You get the UMC included.
- UMC can have various adapters on the end of it, but for UK customers the blue 32A single-phase 'commando' plug adaptor is included; the red 3-phase equivalent is £75 extra
- There was in the past talk of a UK 13A plug adaptor, but no mention of it now. Probably need to build/buy a 13A->Commando adapter. Maybe the 13A adapter for the UMC will reappear later.
- NOT included is Type2 cable for public chargepoints. Tesla will sell you one for a whopping £500!
- CHAdeMO adapter listed at £850 if car has supercharging, or £2000 otherwise. The type2 cable price makes this look cheap!
