“I couldn’t be happier with the service I received! From start to finish, the team was professional, friendly, and highly skilled. They arrived right on time, quickly diagnosed the problem, and explained everything clearly before starting the work. The repair was done efficiently, and the quality is outstanding—you can tell they really take pride in their craftsmanship. What impressed me most was their attention to detail and respect for my home. They kept everything neat and clean, and the price was very fair for the level of service provided. It’s rare to find a company that is this reliable and trustworthy, but they exceeded my expectations in every way. I will definitely be using them again for any plumbing needs and highly recommend them to anyone looking for honest, dependable, and top-quality service.”
“Joseph is very professional, good at his job, he's reliable, his communication is great at all times. Joseph did three separate jobs in my kitchen and bathroom. I'm super happy with the results. Highly recommended.”
“I had my boiler replaced by Carmine two days ago, and he did an excellent job. He was professional, reliable, and very responsive, even late in the evening and at weekends. The whole process was smooth and stress-free. I would highly recommend this company.”
“Brilliant quick service, my mums 89 and had no heating so a big worry. Brennan plumbing put her at her ease and reassured her and worked quickly to solve the problem. Fantastic service would definitely recommend and use for all my plumbing and heating too.. charges and costs are also very reasonable.”
“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.”
“They are a great company, they go above and beyond to make their customers happy. Been using them for years now, would absolutely recommend.”
“Paul did a great job with my boiler service. Super friendly, on time, and really helpful. Would definitely recommend!”

“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 have used Paul for a number of years now on our boiler which is ancient compared to most. Paul is reliable and honest and will tell you what needs doing and what doesn't. He's punctual and his work is impeccable, taking the minimal amount of time needed to resolve the problem. I personally wouldn't use anyone else.”
“I had a issue with my boiler and Jiri came to my house and fixed it quick and it did not cost me an arm and a leg. I highly recommend his services!!!”
“Peter undertook a complete boiler and gas inlet pipework upgrade in our garden flat, his approach was meticulous, professional and he came in well on budget. He also patiently answered our varied questions about products and what was required for our refit when initially drawing up a short list of potential contractors. Peter did not rush when on the job and took a pride in the task at hand. I would happily endorse his services and intend to use his skillset again in the future.”
“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!”
“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!”
“I contacted Heat In London for a last-minute job, and Louis couldn’t have been more accommodating. The team was professional, friendly, and their craftsmanship was top-notch. Everything was handled smoothly and on time. Great service, competitive pricing, and a pleasure to deal with. Highly recommend—thank you so much!”
“Have used Perry and Heating & Gas solutions on 4 occasions now and won't use anyone else for my boiler servicing. Also used them for a full gas installation 3 years ago and have never had any issues at all with the boiler system. Really great company, very trustworthy, always on time and well priced.”
“Another happy customer reporting for duty! These guys at Tailored Plumbing & Heating (Erol and Dave) are just amazing. I had an old boiler system with cylinder, tanks in the loft, and a complicated pipework that needed replacing. They installed a new combi boiler, scale reducer, shock arrestor, magnetic filter, new pipework and nest thermostat. They were punctual, professional and I would definitely recommend them.”
“Dev and his colleague has been great installing the Worcester Bosch Greenstar 4000 combi boiler at our home. From initial consultation onwards Dev has been very helpful and knowledgeable. I’m very pleased with the new boiler and the installation was quick and pain free. I’ll definitely recommend Dev as a very competent heating engineer!”
“An excellent service, with a quick response to a plumbing problem, with follow up to install a water tank system. Ali is local to me and I now feel I have a plumber I can call on in the future.”
“I cannot fault the team at Heatsource! I had a different company out before to fix my boiler- they made no official diagnosis, just started pushing for complete boiler replacement after 10 minutes of aimlessly poking around. I had James out after; he was a delight to have in my home, so professional, polite and friendly and he had the boiler up and running within half an hour- no parts needed! As a single female living alone, I so appreciate a company who won't try and take you for all you are worth and I will only be using Heatsource from now on!”
“Gary is reliable and honest. He has completed a variety of jobs for me from installing a tap, servicing a boiler. Higly recommend. 5star”
“We have an old Valiant boiler that had an error which prevented it from supplying hot water and heating around the house. My housemate called PCH and they kindly assisted us over the phone and helped us troubleshoot our issue. PCH really knows their stuff when it comes to boilers and provided exemplary customer service. 10/10.”
“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!”
“Steve and Ben were amazing, we called them up because our boiler was playing up. We had no hot water. Came quickly gave us a fair price quote and started the work Thursday. They changed several components heat exchanger which got ruined by bad sludge water from old rads. Fitted new pump as well and a new valve. They recommended a system flush after seeing all the sludge build up ect.. and completed the job that day, they worked hard and were very knowledgeable. All problems solved and we're back in business. Would definitely recommend, use again. Thanks Steve and Ben, very happy.”
“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!!”
“Kyle recently changed two radiators for me at my flat and replaced a leaking mixer tap on my bath. From start to finish was a great experience with Kyle. He has brilliant communication and advises clearly and thoroughly on which products will work best and why, for the job you are having done. Prices are clear from the outset and he'll keep you updated on any changes. He really knows his stuff and did a fantastic job at my place. I'll definitely be hiring him again, plus recommending him to others. Natasha Bradshaw”
“I can't recommend Dan highly enough. I thought I needed a new boiler as there was so much wrong with it but Dan did his magic and 18 months later its still working fine. I had him on an urgent call out a few days ago but he soon had the system back to normal with a bit of a service. Many thanks Dan for giving us peace of mind with our heating system.10/10”
“These guys are the real deal. After a few other plumbers to come sort our issue out who never turned up. These guys came down straight away. Chris was the initial contact who was extremely professional. The issue was sorted in a couple days after waiting for replacement parts. Their work was very tidy and neat. Their pipe work was impressive and neat. Hands down a great team and company. Not many of these around nowadays that take pride in their work. Thanks Chris and team…”

“Ryan and his co-worker arrived promptly and worked hard throughout the day installing a new boiler after flushing the whole system through thoroughly and replacing ceased parts, which I was shown, in the process I would definitely recommend him and his Company as I found him to be very reliable, efficient and also self sufficient with respect he nor the gentleman working with him didn't ask for food or drinks as they had arrived fully catered The boiler which was fitted is excellent and our heating and hot water works like a dream This is a Family Business and Ryan was taught by his Father many things, his Father we have always used for our central heating needs for at least 30 years without any problems, and totally trust what he says, he has never let us down in all that time and I just know Ryan his Son will be the same, conscientious, very reliable working to a very high standard Many Thanks Indeed!”
