They were really professional compared to the other builders that came and contacted me. The Project Manager was also on hand to answer any questions I had and offered me adviced on how best to move forward. We ended up refurbishing our entire bathroom which is looking great now. I would highly recommend London Builders.

Overall and excellent job. Turned up when he said, worked hard all day, tidy and professional throughout the week and an excellent standard of work. A friendly and excellent crew of tradesmen who I would highly recommend. Will be asking them back for my utility room and kitchen plumbing.

James did a bathroom refit for us, converting two rooms into one, and installing a new bathroom. Despite being a challenging job, James did excellent work through to completion. He even cleaned up the site after himself. He’s very skilled, honest and hard working. We highly recommend James.

I needed a quick but complete bathroom refurbishment. After being messed about by 3 other plumbers, Andrei was the only person who seemed interested in the project. He was very thorough and made sure I was happy with the results. He was able to look at every part of the project (Flooring, bath & Toilet installment & tiling), and stuck to the budget and quote that was established.

Backlog of work meant our job had to be cancelled, so unable to rate on quality and value (hence average 3 star rating). Had to source alternative tradesman.

Jason and his team were excellent right from quote to completion of the job. They stayed until late to get the job finished in the day. It was a bit awkward to get the tank swapped, but they got it done! Recommended!

Jon said he would be on site 0800 Tuesday and that the job would take two days. I wait in for him, he then advises at 08:47 on that he wont be there but promises to be there 0800 Wednesday. Arrives 09:45 Wednesday. I arranged access for him and was at work on Thursday and didn’t realise until he messaged me at 15:24 that he hasn’t turned into work again, can he come back on Saturday. Messages at 05:28 on Saturday saying he can’t come in but can do tomorrow (Sunday). Messed us around. Won’t use again.

Hired paul to reconfigure my kitchen. He did not complete the job and walked out after 3 weeks leaving numerous jobs unfinished. Many things they did have had to be redone, the finish was shoddy and I don't think he knows what a right angle is. Would obviously not recommend, other tradesmen that have seen his workmanship have told me to report him to trading standards. He left me with a half finished job, saying he was not able to achieve the level of finish I was looking for.
