“Very hard working, knowledgable and reasonable price company. Elias arrived on time, he was straight to the task and fitted my new boiler with care. He is a great, honest and funny guy. If you’re looking for a new boiler installation, look no where else. These guys are professional and reliable.”

“I called RM as my boiler was broken and Rob was able to come at short notice. He was punctual and very friendly. He had the parts and fixed the issue in less than hour. I would recommend RM and happily use the company again.”

“Josh was great at replacing our leaking outside tap and fixing our dishwasher piping and boiler. He’s a very knowledgeable, skilled and friendly chap! He also had a lot of knowledge about general things to do with the house (for example our ongoing mould problem). We would highly recommend :)”

“This is a really good company to use for heating and plumbing issues. Responsive, friendly and good value.”

“Alex helped us understand whether an air source heat pump versus a boiler would be right for our home. We appreciated his deep knowledge of both, and his attention to detail and consideration for our home when installing a new boiler.”

“Great service from Shaibul yesterday who fixed my toilet leak same day for very reasonable price (including parts). My best plumbing experience in Wapping (and I had a couple). And he is very nice person as well always happy to help. Highly recommended!”

“Orpington Plumbing and Heating Solution - Thank you! Fantastic responsiveness. I ended up not using them but they were really responsive and great. It's unusual for this sort of business to be so on top of technology and so responsive, but they are and I appreciate it. Thanks!”

“Romaine carried out a whole range of different works to my property, first fix plumbing for kitchen refurb, boiler upgrades, new radiators and shower. He also dealt with an undiagnosed gas leak and disconnected an old gas fire. There was a lot to get though! He’s very focussed and organised and communicates clearly at every stage about what needs to be done and why. I thought he took a real pride in his work and was very professional and tidy. I wouldn’t hesitate to recommend him to anyone looking for a solid and reliable plumber, a rarity these days! He’s been a great find, and I wouldn’t think about using any other plumber in the future. Thanks Romaine!”

“Extremely professional, responsible, ethical and humble reliable contractor. Punctual and phenomenal attention to detail with strong team management and work planning. Complete peace of mind and work guaranteed provided. Their online care advice and consultancy is way beyond reproach, deeply dependable and trustworthy. Incomparable level of honesty and humility, a quality that is not usually found in contractors and tradespeople.”

“Came out earlier same day notice for my vehicle inspection, Was very very thorough and made sure everything to do with the vehicle was good before purchasing. Would highly recommend!”

“Niaz was very professional. I needed an emergency boiler repair today. Very reasonably priced. He was able to get to my property within an hour and fixed it immediately!! What a fantastic service!! Well Done and Thank you so much!!”

“3 years old boiler was off for 6 months and it would not turn on anymore. At the first visit the engineer after a few tests understood the pump was jammed. We agreed I was going to buy a new one and he was going to fit it when I got the new piece. A few days later the engineer was back at my place to fit it and the boiler has been working properly since. The engineer was flexible with the hours (he came at 8pm the first time and left at 9:30pm), he was honest and most of all the price was fair. I would definitely reccomend him.”

“Couldn't unscrew a nut on our toilet, so I called out the blue, great service, very knowledgeable and taught me a lot. Will be using again”

“We had a saniflow installation done recently, and the service was excellent. The engineer was professional ensuring everything was set up perfectly and explained the system to us.”

“We had an emergency call out on a Sunday for a faulty boiler and Zahid came out that afternoon. He was professional, courteous and conscientious, and diagnosed the problem quickly (after we had been messed around by a previous tradesperson). Would highly recommend!”

“Had a really good experience with them. The engineer was punctual, polite, and got the job done without any hassle. Everything was explained clearly, and the work was completed to a high standard.”

“⭐️⭐️⭐️⭐️⭐️ 5-Star Review for Thomas and Asset Plumbing and Heating. I couldn't be more pleased with the service provided by Thomas. He fixed a persistent pipe hammering issue and a leaking bathroom mixer tap both professionally and efficiently. From start to finish, Thomas was incredibly responsive and accommodating – even going out of his way to source and collect the required parts late in the evening, well outside of normal working hours. His workmanship was top-notch, and he clearly takes great pride in doing things properly. The pricing was very reasonable, especially considering the extra effort he made to get everything sorted quickly. Booking the job with Asset Plumbing & Heating (Tom) was smooth, his communication was excellent, and he's genuinely a lovely person to deal with – polite, respectful, and highly professional. I would absolutely recommend him to anyone needing a skilled and trustworthy plumber. Thanks again, Tom!”

“A brilliant service was provided! I would like to thank the team for their kindness and thorough, professional checks to the boiler and gas safety, for peace of mind in your home. I highly recommend them for residents that need an inspection completed.”

“Been using Steve and the team for over 6 years now on my Mercedes Vito London Taxi. Knowledge, reliability, customer service, affordability and an eagerness to get me back out on the road again are essential traits for me as my vehicle is my livelihood and these boys have never let me down. I wouldn’t go anywhere else for my servicing, maintenance and repairs. Take my view as a great recommendation because having been a London cabbie for nearly 30 years I have used many different garages all over London and I’d rate this place as the best.”

“Can't recommend this business enough. Very clear, came in and did the work. Brian was amazing, gave me very good tips and I trust him and if I ever have problems, I will be going back to them!”

“Yesterday, engineer Ally fixed a leak under the thermostat cup above the heating pipe. I'm very pleased with his approach. He did the job quickly, cleanly, and even gave me advice on choosing a boiler in the future. Also, the engineer arrived at the appointed time. Thank you very much, Ally!”

“Had a boiler breakdown last summer, was given a very competitive price and full transparency and advice to the best options for a replacement. Installation happened 2 weeks later and very happy since. Have used B2B for other properties and highly recommend to friends and family. Keep up the great work!”

“They are so nice and friendly. I like their hospitality. They sort my problem out quickly and cheaper. I am really satisfied with them. Thank you Guys”

“Very good service - Brooke was very helpful in having someone come over at short notice to diagnose an issue with our shower, they were great at finding parts at a reasonable price and Oliver did a great job of installing new unit and getting creative after uncovering some unexpected issues in the wall!”

“Dilwar has been looking after my boiler and heating for a few years now. As well as carrying out routine servicing and gas safety check, he's had to troubleshoot and replace failed mechanical and electrical parts. He's always responded quickly to emails and often arrives earlier than originally planned. I recommend him without hesitation - he's one of the good guys.”

“WPJ made the work on the central heating system hassle free. They accommodated to our timescale as best as they could and were always helpful during phonecalls. They discussed our requirements, flushing the system and fitting a filter, so that we were confident in our choices. On the day, they were professional and pleasant and tidied up after themselves. The cost did not seem exorbitant. I thoroughly recommend this company.”

“I could not recommend Liam enough. He was professional, punctual and good value for money. He was also very thoughtful as he made us a priority when our boiler could not be fixed ( extremely old boiler) and needed a new one. This was very important as we have a toddler and young baby. I would highly recommend him and he is a genuinely nice guy.”

“Fridge fan started making noise and stopped working. Went in with model number and next day they had the replacement fan available for pickup. Thanks so much for tracking down the part and speedy service.”

“Been using this plumbing shop for a while. Service is amazing, people are very friendly and prices are unbeatable. Would highly recommend !”
