The Best Plumbers in Four Marks, Hampshire, United Kingdom (2025)

Excellent boiler service from Simon and friendly, informative customer service from Kelly. Highly recommend

I can totally recommend Simon at Flash Heating and Plumbing. He quickly found and sorted out my leaking system in a highly competent way. He was extremely friendly, polite and explained everything to me. I feel very relieved to have found a trustworthy plumber for any future repairs

Having had an extension done a few years ago, we have had multiple issues with the new plumbing. Those plumbers have since gone out of business (shock) - and i struggled to find a plumber who could come in and fix the various issues honestly and with integrity. I was finally recommended to Simon and I'll never change! He's responsive, upfront, clear and fair. He runs it how a business should in 2025 with clear and quick invoicing and whatsapp messaging. Highly reccomend.

Absolutely top class service. Got back to me quickly. Fixed my leak in my airing cupboard and serviced my boiler the next day and replaced a pump that the previous engineer put on upside down!!! Friendly and very reasonable price too. No hesitation in recommending Simon.

We were recommended Flash Heating and Plumbing solutions by our surveyor Brian Gale Surveyors as we needed additional checks done for a house purchase. Simon was great, really quick to respond when I reached out and after being in to do the checks was so fast to send over the details we needed. 100% would recommend.

Completed a bathroom from start to finish which included stripping out,plastering,tiling,bathroom design and fitting bathroom, was a 5 star service ,very professional and clean,tidy and reliable and I wouldn’t hesitate to use this company again. Thanks for all your hard work and giving me my dream bathroom

Dan did a brilliant job solving a plumbing problem in my house several years ago and I’ve been highly recommending him to other people ever since. This month he took on another challenging project and he again showed his first-rate skills and attention to detail - and I now have a beautiful new bathroom. Dan is always courteous, patient and totally trustworthy and I’ll continue to recommend him without reservation.

Can't recommend Dan highly enough. We had a fault that meant we had no heating or hot water. I contacted Dan late that day and he responded within an hour to say he would drop by next day. He arrived next day, diagnosed the fault, went to get the part, came back same day and then fitted the new part. Everything back to normal in just over 24 hours. Can't ask any more than that. Thanks Dan

Contacted Dan about serving my boiler and renewing kitchen tap. Dan was on time happy with the work carried out and already recommended to friends

Dan and Al replaced our old failing boiler with a new Combi boiler. From the start, we had great communication from Dan. He is clearly knowledgeable, professional and has a calm nature. Just as well, as a lot of the work was in quite confined spaces, removing and modifying pipework. Great work, thoroughly recommended.

Absolutely brilliant service, Harry managed to fix a plumbing issue that no one else could solve, he communicated excellently, arrives when he says he will, is a very tidy worker and above all knows his subject. I will be using Harry for all my plumbing requirements in the future and would recommend highly.

The heating engineer was extremely helpful testing my radiators and explaining controls. In addition, he provided a gas safety certificate after checking my gas supply and cooker. Highly recommend this personal service - have used OnTrack Heating for over 4 years.

Outstanding Service from OnTrack Heating! We recently had OnTrack Heating sort out our underfloor heating, and they did a fantastic job from start to finish. Communication was excellent from the outset—they kept us informed throughout the process, explaining everything clearly. They arrived on time, worked professionally, and installed all components to a high standard. Everything was thoroughly tested before they left, giving us complete confidence in the job. Now, we have a wonderfully warm kitchen diner, and we couldn’t be happier! Highly recommend them for anyone needing heating services.

Just 10 weeks after moving home our 'new' boiler broke down. Thankfully, with outside temperatures extremely low, Dave recognised our vulnerability and his team installed a new boiler with remarkable speed. The new boiler is doing a great job, and we are so grateful for their excellent service.

I’ve been using OnTrack for the past three years to service my boiler, and Luke has handled each visit. He’s highly knowledgeable and always polite. I wouldn’t trust any other company for my heating needs.

Totally reliable and trustworthy. Recently serviced my boiler and in the past have replaced all radiators in my home. No fuss, on time, and very professional. Very happy to recommend, you will not be disappointed and their fees are very reasonable.

From start to finish of installing a new gas boiler, Upsher were efficient and professional from Claire, Lorraine for customer service to Mark and Ethan that completed the work. Thank you

Great experience with Upsher Heating + Plumbing! Claire provided excellent customer service and kept us informed throughout the process. Macca and his colleague fixed the issue promptly and expertly exactly as described. Fair prices and quality work—highly recommend!

Macca came out to sort out a loud noise that was coming from upstairs. I was notified by text of timings. He was such a polite young man and knew what he was doing. He didn’t take any shortcuts and even though it was 5pm he kept working until the job was finished. 100% recommend this company. Macca is a credit to your company.

I've used ECS for a number of jobs both large and small. We did extensive remodelling in our house and used ECS to completely re-plumb the building, fitting new underfloor heating and radiators, boiler and plant room. They did a great job and over the past 4 years I've used them for annual boiler maintenance, tap leaks and more recently sorting out a drain issue. ECS are always on time and have often coming out quickly or at short notice. They provide a quote before doing any work, payment is easy and they produce a job report so you can see exactly what's been done. I highly recommend them!

We had our heating system upgraded by ECS with a new boiler installed. They were great from the first quote to getting the job done. They listened to us from the start, discussed our options, and were contactable and responsive during the job. The team working at our house were tidy and respectful. I would recommend them highly!

Ross and the team at ECS have helped with various things over he passed couple of years, heat pump servicing, plumbing work etc and they’ve been fantastic. Great company, very well organised and reliable.

I could not be more impressed. We had an issue with our air source heat pump system. ECS responded immediately and identified the issue instantly. They suggested several options and talked through each with us. They did a superb job and constantly kept cost in mind ensuring we received the most cost effective repair. We’re delighted with the result. I really couldn’t recommend them more highly.

We were very pleased with the work (new bathroom) that Mark Smith did for us. Their advice with design and choice of materials was really helpful. The office staff made themselves available whenever we needed information and responded promptly to our questions. The quotation was clearly set out and reasonable. The tradesmen who worked on the project were thorough, careful and clearly very skilled. They kept us up to speed with what they were doing and were very considerate when it came to the inconveniences of having to turn off the water supply! They were punctual throughout and completed the work in the promised two and a half weeks. Overall, we'd have no reservations in recommending them.

We used Mark Smith Plumbing last year to install our new boiler so we asked them to replace 2 leaking syphon valves in 2 toilets. Despite some difficulties in obtaining the correct parts and the job expanding into a bigger one, we were very pleased with the final result and the final invoice was very acceptable.

Very pleasant person came to service our boiler. He did a thorough job and fixed a problem we had. Easy to book and pay online.

Excellent service from start to finish. Communications were very good. The plumber completed the work in a very timely and professional manner. He was also very helpful and pleasant. I have no hesitation in recommending Mark Smith plumbing and will be using them in the future.

Just wanted to say thank you to Jamie and team. Had a very unpleasant job of trying to work out what was blocking outside pipe leading from toilet. Guys worked hard and did a great job. Family now very happy to have a toilet upstairs that works.

Jamie & Wally did an excellent job in removing an old leaking shower and replacing it with a new one. Work involved removing the shower rear wall panel, supplying and fitting new sub frame with plasterboard then re-tiling etc, new wall. All done with expert experience with a minimum of disruption plus, completed in two days and at a very competitive price!!!! Many thanks JRS . TONY
