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.

Had a very positive with Mark and the Unique Lofts team for our loft conversion. I would highly recommend them. Michael and Brad (our team) were friendly, dedicated and hardworking. Our neighbours, who had the skip chute cross their garden, also shared how considerate and friendly they were. Michael kept me in the loop, followed up on my enquiries and gave some really helpful advice in moving airing cupboards and opening up the loft space for more natural light. All in all, highly recommended.
