Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.
