"I highly recommend MWH Heating and Plumbing for all plumbing and all issues with gas boilers. Courteous, professional, and very reliable. A good plumber is hard to find. Once you have used MWH, you’ll never use another plumber. Exceptional service!"
by Colin Doughty - Cardiff Bay, Cardiff
"We’ve used MWH Heating and Plumbing on a number of occasions for boiler servicing, gutter repairs and most recently the installation of our extremely heavy and awkward cast iron vintage radiator! The service provided by MWH Heating and Plumbing has been exceptional every time; friendly, professional and affordable we would not hesitate to recommend him to others."
by Helen Davies - Riverside, Cardiff
"We cannot recommend MWH Plumbing highly enough. Helpful, trustworthy and very reliable. Fantastic service time and time again!"
by Lynsey and Jamie Coleman - Lisvane, Cardiff
"We have had a fabulous experience with MWH installing and building an en-suite into an existing bedroom. Coordinating plasterers, carpenters, plumbers, electricians and tilers could have proved difficult but the result is fantastic! The attention to detail was awesome and all the lads were dedicated craftsmen. Thanks so much! Judith and Dave."
by Judith James - Llandaf, Cardiff
"We are so pleased with how Marc and his team have dealt with our (not insignificant!) project. They have an unflappable attitude and are meticulous about quality. The work undertaken has been of an exceptionally high standard and we would not hesitate to recommend them."
by Huw and Angharad Triggs - Tongwynlais, Cardiff
"The MWH team are always on hand for us here at Cardiff Arms Park. No matter how large or small the project we can always rely on them to deliver a high quality service, within budget and on time. Whether they're transforming our changing rooms and showers, installing a state of the art recover suite or reviving the stadium heating system, MWH have given the home of Cardiff Blues a new and efficient lease of life."
by Jamie Muir - Cardiff Arms Park
"MWH have been top-notch from the first time we used them over 3 years ago with our cranky old boiler. They've seen us through everything from boiler servicing, keeping an aged boiler alive as long as they could (until the fatal fault), fitting our new boiler and many little things in between. Marc and his team have always proven to be professional, friendly, punctual and reliable. Would happily recommend them to anyone. Top notch service from a fantastic company!"
by Pete Kelly - Risca, Newport
"Having tried 3 other plumbers who either didn’t turn up, or didn’t come back, I found MWH. Can’t fault them! Initial response, assessment of the issue, and necessary repairs were all carried out effectively and efficiently. No hesitation in recommending them. Thank you!!"
by Chris Binstead - Marshfield, Cardiff
"What a saviour! Our boiler stopped working last night, our house temperature dropped to a chilly 12 degrees but he was happy to give instructions over the phone, as not operating today due to snowy weather conditions, and got it working. Thank you!"
by Carolina Avila-Jones - Pontcanna, Cardiff
"Gwasanaeth gwych a Chymraeg gan Marc a diolch i’r bois i gyd am eu gwaith safonol. An excellent service from an experienced team and will be recommending them to everyone! Diolch"
by Meurig Jones - Tongwynlais, Cardiff
"Top class workmanship and brilliant customer service. I'd give them 6 stars if I could. Easily a plumbing firm I'll be using for life."
by Marios Yiannou - St Mellons, Cardiff
"Fantastic service from Marc and his team following my DIY disaster which resulted in a burst central heating pipe. I would highly recommend MWH to anyone looking for a highly professional and trustworthy company."
by Gareth Rees-Jones - Penarth
"Excellent Service, friendly Engineers. Would highly recommend! We first got in contact with Marc at MWH for a boiler service when we first moved to Risca a couple of years ago. He was recommended by a friend at work and we are very pleased he was! We are very happy with his service, professional manner and honest advice from the start. If we could give 6 stars we would!"
by Pete and Pauline Kelly - Risca, Newport
"What a find this firm was for me! I had a problem with my unvented hot water cylinder - water was leaking to the overflow when the cylinder was heating up. They quickly identified the problem and stayed on at the end of the working day to remedy the issue and leave the cylinder installation safe. Efficient service at reasonable cost from people who are good at their job. I couldn't ask for more."
by David Gough - Rhiwbina, Cardiff
