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.

Rhys is a young man who was polite and professional, who did a good job and cleaned up well afterwards. He charged me the amout he had quoted on the 'phone even though it probably took him a bit longer than he thought. I would definitely use him again.

I am very happy with Richard, he was polite, informative, reliable as he turned up on time. Attention to detail, as he measured everything twice to make sure it was correct. He even tidied up after himself. The lights look amazing and the extra socket he added is a godsend as I've used it twice already. I'd certainly recommend Richard. In-fact I've got 3 jobs lined up already.

Matt undertook a 4 month project which involved removing walls, installing flooring, kitchen, bathrooms, new radiators, windows, bifold doors. He was 100% reliable and was onsite daily, always happy to give guidance and advice and worked tirelessly to ensure our building went to plan. His work is of a high standard and he has a positive outlook making it easy to work with him and resolve issues. We are over the moon with the end result and would not hesitate to recommend Matt or use him again.

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 an Electrical Certificate for my rental property. I chose this company because the price was competitive. I knew there were issues with the electrics in the flat and I wanted a new oven and hob installed. Nicholas clearly explained everything to me what was required and why. I am so happy with the high quality of work and the timely manner in which all jobs were completed. The old oven and hob were taken away. I have received all certificates and documents that I needed.
