Discovering a leak led me to the Thames…

Discovering a leak led me to the Thames Water website to report it, where I found a list of suggested plumbers. Water Mains Engineering UK Ltd was listed at the top for my location. Although I planned to contact the first three, I dialed their landline and was promptly assured of a return call. Marlon, the owner, reached out within minutes. I didn't need to contact anyone else; I'd found the perfect match! Marlon and his team kept me updated via WhatsApp, messages, emails, and phone calls. Even when I mistakenly called them late at night, Marlon quickly called back. The job involved challenging, old London plumbing, but they tackled it with exceptional skill and precision, dedicating long weekend hours to ensure perfection. What might have been a daunting experience was flawlessly handled, timely and efficiently. Marlon’s expertise and professionalism are unparalleled, and I wholeheartedly recommend him and his team.

Rated 5 out of 5 stars

Excellent, hard working team, great communication.

I found a leak and went on the Thames Water website to report it. On the site were a list of recommended plumbers. Water Mains Engineering UK Ltd was on the top of the list in my area. I was going to contact the first 3. I phoned the landline number which was answered straight away by someone who said I’d get a call. Marlon, who owns the company, got back to me in minutes.
I never contacted anyone else as I had hit gold!
He and his team kept me informed all the way with WhatsApp, messages, emails and phone calls. I even accidentally phoned the number late at night, and he phoned me back immediately.
The work was very difficult being old London plumbing. They did it extremely well with great attention to detail, working long hours over a weekend to get everything right.
What a thought would- and could have been a nightmare was managed beautifully and on time. He is highly qualified and knowledgeable. I cannot recommend Marlon and his team enough.
