One to be careful with is the electrician Ben. The work seems alright, but his advise left us with excessive lighting in Kitchen and sitting room and our decision against TV sockets in ALL rooms was interpreted as NO TV and phone socket at all, which then later had to be added at extra cost and left the choice of suppliers limited. His crew also did the plumbing and the bathroom installation and the later was not done to the general standard of U&U constructions work.
