Plumb London recently replaced two very old radiators in our kitchen, and we are very pleased with the results. The engineer was very knowledgeable and courteous, and ensured that all the other radiators in the house were bled properly before completing the job, as the system had to be drained down. We were very pleased with this efficient service.

They supplied a competent chap who knew the boiler and related control devices. Found the fault on first visit and came back next day with the replacement.

Plumb London deliver a consistently excellent service. In 2025, my boiler was repaired swiftly before the annual service, and the skilled, friendly engineer arrived at the allotted time after a courteous 30‑minute call ahead. The fixed service charge remains very reasonable. I always find Plumb London highly competent, professional, friendly, and reliable. They remember who you are - they installed my boiler in 2017 - and they’ve provided exceptional service ever since. I wouldn’t hesitate to recommend them.

I used Plumb London every year to service my boiler and for other plumbing needs. They are friendly and professional. The work is thorough and any issues is dealt with quickly. Happy to recommend them.

Would always use this company

I called the same day my boiler was leaking and they promptly assisted me and sent an engineer to check within the same day in the evening. Following day they shared all the findings and the proposal, so we opted for a new boiler and they have done everything and sent the same engineer the day after for installation, which took the whole day. Very impressed with the service and the quality. highly recommend

Arrived punctually, knew what he was doing, worked efficiently. Checked the whole system as well as fixing the problem.

Cautious yet thorough and professional plumber. They got the job done and done right. It’s a relief to find a real plumber and I’ll likely be calling them first next time.

I've used Plumb many times over the years

They are always reliable, trust worthy and have great workmanship

I always recommend them

They are friendly, importantly honest, reliable, well priced and know what they are doing and not pushy with up selling shizzle. A rare gem in trade world and definitely recommend.

Massive Thanks

I’ve used PlumbLondon for over 10 years and I think they are brilliant.
The engineers are friendly and professional.
I would highly recommend in the Sutton area.

I've used Plumb London a few times for different jobs, organising the appointment is easy and where there was a problem which meant the engineer couldn't attend the pre-arranged date, they told me in good time and rearranged for quite soon after. The engineer this time was the same one who checked and serviced it last time, which meant there was continuity of service and all went smoothly.

Got in touch with Plumb London about my leaky shower. They go back to me instantly and I had someone booked in straight away after a quick phone call. Can’t fault the customer care. The job was undertaken with care and everything explained. Matt did a great job! They even gave me a courtesy call after the job was completed to check all was ok. Wouldn’t hesitate to recommend them in the future! Thanks so much.

Really reliable firm for a boiler service. Peter was great and has for the past few years managed to squeeze into a very tight spot to give the boiler a service. Really appreciate the reliability and flexibility.

Vlatko diagnosed the boiler fault quickly and returned later the same day to fit the replacement parts. Excellent professional service.

Had a great experience, solved the problem. Very good at keeping us informed throughout of when they would turn up.

Great job, leak under floorboards identified and fixed quickly. Very polite, professional. I would recommend. Only issue is floor a bit creaky now but this is easily fixed. I have used this company many times and always happy. Reasonable prices too. Thank you

Fast service (next day) for the initial assessment of the issue. Then, even though it was not an emergency per se (needed broken shower pump replaced and associated inter-connecting pipe work), the team managed to source the part and fit me in the very next day. Engineer was polite, knowledgeable and very professional. A pleasure to have in the house and left us very happy customers! Will definitely use again!

Had a small issue with our boiler timer which unfortunately turned into a full boiler replacement after the old unit failed a carbon monoxide test. The team at Plumb London were fantastic in arranging an immediate installation for a new Glowworm boiler, and everyone in the office was extremely polite, professional, and clear about the process.

My only concern was with the engineer. His tone came across as harsh and caused unnecessary stress for my partner and me. While I fully understand the seriousness of the situation, being told repeatedly that the boiler would “never pass” a safety inspection felt more like a reprimand than helpful guidance. We aren’t experts in central heating, and I had ensured the boiler was serviced this year and the year before, so it was upsetting to feel blamed for something beyond our knowledge.

That said, the engineer did eventually give us the options and did a good job removing the old boiler and installing the new one quickly, and the installation itself was done well.

Overall, the service was prompt and professional, though I hope future engineers could approach stressful situations with a bit more understanding and clear guidance rather than alarm.
