Loft Conversion- 22 Aug 2025
I had Panesar Builders build a dormer extension garden room and a bedroom above the garage around two years ago. I deliberately waited before writing a review to be sure there were no hidden issues — and I can happily say everything has held up perfectly. Before choosing Panesar Builders, I researched and spoke with many builders. His quote came in at a fair, middle-ground price — not the cheapest, but not the most expensive either. I felt confident in my choice, and two years on I can say it was absolutely the right decision. The work was completed to a high standard, communication throughout the project was clear, and the whole process was smooth. Two years later, the extension is still solid, with no problems at all. It has completely transformed our home. I really appreciated the professionalism, reliability, and attention to detail shown. I would have no hesitation in recommending Panesar Builders to anyone looking for a trustworthy builder who delivers quality work that lasts.

Groundwork & Foundations- 22 Apr 2026
Artan and his brother built a shed concrete base in our back garden that is located on a steep ish hill. They are professional and polite, and Artan went over and above to ensure delivery of materials was resolved due to our road being a little challenging for an inexperienced lorry driver. They’ve done a stelar job and we are very pleased with the end product. We are planning to use their services in the near future for other works.

Plumbing- 20 Jun 2026
My husband and I super impressed with the work done for us. I was a bit skeptical at first because I couldn't see a lot of reviews under this company but just felt to go with them. Things that impressed me: - Prompt response to my messages - Sent me a proposal with the cost so I wasn't guessing. - Was willing to order and pick up a tap for me on his way. - when I said that I needed the work done today, he was able to fit me in. - We agreed on when he should come, he communicated when he was 30 mins away and arrived just in time. - Friendly, honest and straightforward guy. He and my husband were talking like they had known each other before. - He was also able to do a quick kitchen sink work for us whilst here. - He was willing to answer our questions. - The tap he fitted in place of the old one is even better. Our old one splashes water all over when opened, even gently but this one isn't like that. The overall service has been incredible. Thank you so much. Will defo be in touch.
