Always excellent and flexible service. Bought our boiler from them and have had a service every year since.

Found these plumbers through Checkatrader, arranged for a plumber to come out the next day. This appointment was cancelled but I was only notified when I rang them. Someone came out the day after, couldn't find why I had no cold water in the bathroom. Said he would discuss with colleagues & get back to me-3 weeks later I'm still waiting. Basically paid £108 for nothing. Found another plumber who diagnosed the problem straight away.

Steve was professional and and he got the job done efficiently. He also explained things as he went along which was very helpful. I would definitely recommend this company.

Have been with them for a few years now after from installation to service each year and they’ve been top notch!
They’re great at reminding when the service is due to keep it all in order and are quick at the service itself and always polite.
Same person has been the last few years, Adam, and he’s great - punctual and efficient!

Absolute scam rip off company - DO NOT USE.

I called them to report a leak coming from my bathroom in a top floor flat. The leak was a slow trickle going into the flat below so needed to be fixed before it became a major issue.

I explained the situation to their office staff and asked if they would need access to the flat below. The resolutely said they would not require access to the flat below.

The plumber turned up, took one look at bathroom and said he couldn't do anything without access to the flat below and promptly left, having spent literally under two minutes on site.

I call again to explain the situation and they offer to send the plumber around again. This time I coordinate access to the flat below. The plumber comes around, takes one look at the flat below and promptly says the issue is leaky sealant around the bath. Clearly proving the plumber did not require access to the flat below.

The plumber then left stating he didn't have the equipment to complete the job (so a plumber rocks up without bathroom sealant).

A third call to this clown show and the plumber finally comes around with sealant and doesn't ask for access to the flat below and finally replaces the faulty sealant.

Total charge £492 for a 30 minute job and a tube of sealant that costs around £10.

DO NOT TOUCH THESE SCAMMERS.

Edit: I responded to Plumb Nation's request for further details by providing the invoice number 62642, but they have failed to provide a further response. Unsurprising as the invoice literally states £384 to remastic but omits the previous call out charge where they did nothing.

They did a good job quickly supplying and fitting new boiler

Efficient service, with great customer service.

Plumb London have been looking after my boiler and heating system for ten years , always clear honest, prompt polite and tidy! This year we have had historic leaking radiator issues that resulted in the boiler loosing pressure. they were very persistent in solving the problem and replacing failed radiators , always on time and keeping us informed. The work was led by Mo with Conor in the office. excellent service.

Plumb London completed the gas safety certificate in my house. On time, very polite and showed the tenants how to operate the boiler - very helpful - Thank You.

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.

I've used Plumb many times over the years

They are always reliable, trust worthy and have great workmanship

I always recommend them

Have used PlumbLondon dor yearly Boiler Service since 2017 and repairs when broken down. Also got them to fit gas cooker.

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
