EXCELLENT Based on 52 reviews Posted on Mr ChrisTrustindex verifies that the original source of the review is Google. Called Mark up on monday morning as my boiler was dripping water and losing pressure. They came out first thing the next day , Isolated the issue so it no longer leaked, Came back the next day with the parts and got it sorted. Also kindly fixed a slow running kitchen tap. Very prompt and friendly.Posted on Maxwell TylerTrustindex verifies that the original source of the review is Google. Mark and Darren recently replaced our boiler, hot water system, and bathroom toilet, and we couldn’t be happier with the results. From start to finish, they were professional, reliable, and incredibly easy to work with. Mark kept us fully informed throughout the process and made everything straightforward, while Darren's workmanship was excellent and everything was completed to a really high standard. They were tidy, respectful of our home, and worked efficiently without cutting corners. The difference in our heating and hot water has been amazing, and the new bathroom toilet installation was handled perfectly too. Highly recommend both Mark and Darren for anyone looking for trustworthy, skilled plumbers who genuinely care about the quality of their work. Ps, If you are a baker, they love a sponge cake and a cuppa tea ;)Posted on John MartynTrustindex verifies that the original source of the review is Google. Mark provided us with a quick response and a job well done at a reasonable cost. He not only remedied the identified problem, a leaking WC waste pipe, but also attended adjacent unseen issues. I will certainly use his company in the future.Posted on mark lundTrustindex verifies that the original source of the review is Google.

MFP&H have carried out various works for us, up to and including a new boiler install, they are always very proffesional, carry out work to a good standard, and are clean and tidy, whilst remaining good value for money.Posted on Matt McDonoughTrustindex verifies that the original source of the review is Google. I am slightly nervous when it comes to hiring tradesmen off the internet without a recommendation, however once we had used Mark, these fears were put this to rest. We initially had a heating Survey by Mark as part of a house sale, which revealed the need for a new boiler as the system had been playing up. Mark was upfront, very quick to visit us (next day) and talked through our options. He then sourced a quality boiler (Worcester) for us, at a very competitive price and fitted it within a matter of days. His labour costs were superbly competitive and he followed up with all the legal documentation required. I highly recommend Mark, and we now have a local trusted plumber and heating engineer we can trust and rely on!Posted on Karina JorgensenTrustindex verifies that the original source of the review is Google. New to the area and he sorted us a new boiler. Great service and communication throughout. Good to know we have a go-to already!Posted on Lucy MurphyTrustindex verifies that the original source of the review is Google. Mark and Darren have recently carried out a boiler replacement and fitted a new radiator in our conservatory! We were very pleased with their workmanship; they are a great team, very knowledgeable, helpful and easy to communicate with throughout the whole process. Would definitely recommend them, in fact we have already got them booked in for our bathroom and cloakroom refurb :) Thank you very much!Posted on Steph SmithTrustindex verifies that the original source of the review is Google. Such lovely friendly guys! Came and fixed my broken toilet same day, came with the parts and were super friendly. They even fixed my taps at the same time. Really reasonably priced and trustworthy. Really recommend!
