I’m so pleased I came across this company, following a leak in my flat. Louis was very efficient, professional and helpful in detecting the leak and making sure he worked with minimal damage caused. I’ve already recommended him around and would use this company again.

Highly recommend - Louis was super prompt coming to assess our boiler, sent out the quote the same day and we were booked in (as an emergency) for just a few days later. Josh & Louis were super efficient on the day and had the new boiler installed in no time! They were both super polite, clean and answered all our questions. Couldn't recommend them both more!

Louis was top class. I had to have a shower fitted at really short notice and he made himself available even late after completing some work. Highly recommended and extremely professional and it’s nice to know he’s on the other end of the line if more work is needed for the future.

Marching-On 24/7 Plumbing did an excellent job with my shower installation. The team was professional, efficient, and completed the work to a high standard. They arrived on time, explained everything clearly, and the shower works perfectly with great pressure and no leaks. Fair pricing and tidy work. Highly recommend them.

Louis was quick to act when getting an emergency call out and was here very quickly. Access for maintenance was very poor from the original installer , Louis was quick to call in an extra pair of hands to assist when required. The leak was identified and repaired in a timely manor, would definitely recommend to anyone ! Thanks for your help Marching-On!

Louis came and explained what needed to be done and he did it. Replaced valves in a Perrin and Rowe triple tap. Worked patiently to get the old valves out and successfully installed the new valves. A job well done!
