Public evidence profile · Checked June 2026
How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Water tank overflow
WPS repaired a severe leak with prompt action from excellent workmen with the minimum of delay at a sensible price. Office staff couldn’t be more helpful. We have used WPS a number of times and we wouldn’t hesitate to recommend them.

Highly recommended
Contacted WPS to fix a leak from the toilet from one of our bathrooms. I was given initial advice as to how to determine if it was a leak from usage or otherwise, and that would determine how urgent the matter was. Turned out it was a leak from being used, therefore it was a non urgent job. The appointment was booked. The charges were made clear at the time of booking. An engineer attended on time, got straight to the job, and fixed the other issues we also had. The engineer was quick, replaced the parts that needed replacing, tested the whole bathroom to ensure it was all working. He gave me a run through of why the toilet was leaking and how he fixed it and the other two issues. The bathroom was fully functioning within 2 hours of the engineer being there. He assured us that it should all work now, and if not we should contact them. Since then we have not had a problem with the bathroom. I would not hesitate in recommending WPS.
Work completed:
Great work and on schedule
They were able to solve all the problems that we had. Install a new boiler, replace four radiators and some pipe work and flush the system. They also got the fitted carpets back in place as if they had never been moved. The guys doing the work were conscientious, professional and friendly.

FANTASTIC SERVICE
I called WPS Plumbing Service at short notice in the morning as had blocked toilet. They arranged for someone to attend my address in the afternoon and did a brilliant job, they were quick, professional and friendly and would definitely recommend them and use them again
Work completed:
Great work, very efficient and helpful team
I came to WPS in quite a desperate situation - I had asked British Gas to fix a boiler issue (that they had flagged up a few months before) and they said not only that they couldn’t fix the issue, they verbally told me the boiler was safe and then wrote a summary report that it wasn’t safe, and refused to change the report. I was obviously very worried the boiler wasn’t safe and would make my home insurance invalid! I called WPS as my parents used them before and they went to see the boiler within 3 days. I also called the office to discuss accessing the property and their admin team was incredibly helpful. They were efficient, helpful, and straightforward. I can’t recommend them enough!
Work completed:
Excellent and efficient work, carried out professionally and with care.
The work entailed a new boiler and mag filter, new circulation pump, new valves, new air release, new shut off valve and minor alterations to the pipework, re-siting of valves, and a full system flush. The team who attended carried out the work with the absolute minimum of disturbance and with care to my property. They worked efficiently and professionally, and I was confident to leave them to the work. They were personable, courteous and friendly at all times, and it was a pleasure to work with them. At no time did I feel inconvenienced. I was delighted that the majority of the work was completed on the first day, enabling us to check the system and run it through the night to settle it down. The remainder of the work was completed the following day whilst they carried out a full system flush. The team created a good atmosphere whilst doing a very successful, professional and tidy job. WPS also registered the boiler on my behalf. All in all I'm delighted with an excellent result, which was achieved to time and to budget, and which actually exceeded my expectations. I now have a far more efficient central heating system as a result.

Fixed a leaking shower
Adam came on Saturday to fix a leaking shower that involved taking the plate off a tiled wall. He fixed the problem (which Thames Water had advised me about as my meter was running constantly) but also advised on some other work on my radiators and heated towel rail I asked him about. He was helpful, polite, skilled and professional. I was recommended WPS by my builder and will definitely use them again for all my work.
Work completed:
BOILER REPAIR
For a long time, our hot water was very slow to power our shower. We had the boiler serviced every year by the manufacturer who never noticed the problem. Watertight came and checked the boiler and found the unlying fault. A shut off valve, which was opened and rapidly restored the flow to normal. We have been able to reduce the water temperature. They also replaced our smart thermostat with Hive and that has made an amazing difference. I will now use them for all my plumbing needs
Work completed:
Fantastic service
I used Watertight Plumbing Services for a problem with my underfloor heating. They were highly professional, knowledgeable and a pleasure to deal with. The engineer not only fixed the problem, but also noticed something else wrong with the boiler and fixed that too. I can't recommend them enough - great value too.
Work completed:
Boiler service and repair
WPS initially installed my boiler around 10 years ago and have maintained it on a regular basis since then. They are responsive, professional and easy to contact via e-mail or phone, and work is carried out to a very high standard. It is particularly good to have continuity and still be working with the same team that installed the boiler.
Work completed:
I would highly recommend
WPS are fantastic plumbing and heating engineers, they are reliable, efficient and well priced. Any radiator or boiler problems, they are the ones to fix it. I highly recommend them to everyone.
Work completed:
Professional service and reliable
I used Ian and his team to replace my radiators due to remodeling in my house and also upgraded my boiler. He came round and calculated the correct sizes and BTU for all our rooms and fitted the correct size boiler for my requirements. His team completed the work within the estimated timescale and the price was fair. Elaine in the office was great and kept me updated with what was happening which I appreciated as I travel and couldn't be home. I would happily recommend Ian and his team for all plumbing and heating work.
