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.

Whilst fairly pleased with the work, the renderer (Anatoly), did not place scaffold back into existing location. A scaffold ladder was left hanging by a single clip. Bars and boards not returned closer to the building leaving huge gaps. Red brick dust has stained 4 days after completion. The disgraceful condition of the scaffold is gross in my opinion

David and his team were very quick, responsive and professional. They have not only insulated and applied new rendering to my house but also addressed a couple of minor issues (repointing of coping stones and correcting a flashing detail). Very good contact throughout the whole process. Highly recommended!
