Do I have 3 phase to to my house?

Are you friends with your neighbour?
I’d put a meter between their re live and your live to see if there are different phases present 400+ means yes

Better still: take a feed from each neighbour, and run them into one red socket.

Ta very much everyone.

If that cable is 3 phase, I would be surprised if they would give you a new feed to a 3 phase head fed from there its only a small cable so any bigger load would probably affect joint properties.( that's what i would expect locally your DNO may be ok).
