What We Service (And What We Don’t)

We currently specialise in HIU boiler servicing only. Unfortunately, we don’t service gas, oil, or LPG boilers at this time, as many customers now use care plans from providers like Boxt or British Gas. However, if you’re looking for proactive maintenance and peace of mind beyond your boiler, we’ve got you covered with our Plumbing Property Care Plan.

1 Free Preventive Maintenance Check
1 Free Emergency Callout* (terms apply)
Discounts on Labour for any plumbing works

It’s a smarter alternative to traditional boiler-only plans, giving you broader protection for your pipes, fixtures, tanks, and HIU systems.

Fantastic service from Mr 24 Hour Plumber! Scott and his lovely apprentice Emma came out within the hour to help fix an issue I was having with my toilet. They quickly figured out the problem and had it sorted in no time.

They were both so friendly, professional and approachable and what really impressed me was that they took the time to show me what to do in an emergency if I ever had the same issue again and needed to turn the water off. That extra bit of advice was really appreciated.

I wouldn’t hesitate to recommend them to anyone looking for a reliable, honest and efficient plumber. Thank you both so much!☺️

 Trustindex verifies that the original source of the review is Google. I called Mr 24 Hour Plumber Ltd  yesterday to sort out a few leaky, drippy problems that had arisen in my elderly Father's house. Scott and his apprentice turned up on time, established what needed doing, gave me a price and got stuck in. Very efficient, friendly and explained everything well. Thank you so much Scott and Emily for an excellent, professional service xxx

 Trustindex verifies that the original source of the review is Google. I phoned Scott early Sunday morning, and he arrived early afternoon he sorted all our problems (and there were many). As we had just moved into our new house he gave me lots of useful advice to maintain our house. He was very knowledgeable and professional and knew his trade very well. What i also liked was the fact you talk to the tradesman who was doing the job and not to a call centre who haven't got a clue.  I can't speak highly enough of Scott and wouldn't recommend any other company. Thanks Scott you done great
