Highlights
“Good Experience, communication, timeliness and work performed all excellent”
“Darren was extremely helpful and friendly. Respectful of our home. He was the ideal person to replace our boiler.”
“Super quick in responding to 'call out' for the work needing to be done and they were able to send someone out that morning to check the issue. The issue was found pretty quickly and they were able to go off, source the part and do a full repair all within about 3 hours on the dame day. Great service and great guy that they sent over that explained everything he was doing and what was needed and why. Very reasonable cost.”

Overall it was a good experience. The survey was carried out promptly and the qoute was provided the next day. The plumber was polite and efficient. The only criticism I have was I had to ring the office a couple of times as the plumber was late due to problems with a previous job. would have been better to have been kept informed

Really attentive company, offered to go out of their way to help when the original time wasn't met. Plumber arrived, unblocked the pipes and left with very little fuss. If you're like me and super paranoid about being ripped off for simple work, these are your guys! Trustworthy, positive and good at what they do. Recommended.

The initial consultation from Plumb London was excellent, and then a call received quickly do explain a detailed quote. The appointment for the work was quick and the work to the bathroom carried out quickly and expertly by Mounir to a high standard. From start to finish a seamless service and a very happy customer.
Very prompt response. Was a quick easy fix to stop the leak, but didn’t feel comfortable doing it myself and glad I have piece of mind all fixed by a professional! Thank you!
Verified by CheckatradeGreat annual boiler service
Plumb London provided a great service with our annually builder check. Really easy process. They reminded us of the service in advance so we were covered then were efficient and communicative throughout.

Very professional tidy work good service
Engineer arrived quickly and showed us how to fix the error in future too
Verified by Checkatrade
Had a boiler service carried out - overall a good service, no issues and engineer called to say when he was on his way. This is one of the main reasons I use Plumb London - they call if the engineer can’t make it or is running late so you are not left waiting for a no show.
Verified by CheckatradeBoiler issue
The Plumb London team were great. Par on the initital visit dig a thourough check of our boiler and heating. We were not surprised by the recommendation of a new boiler as the old one was 20+ years old. Par and Stefan took a day to completely sort everything including the new boiler, additional pipes and radiator caps. Everything was as expected from an execllent business. I would use them again and recommend.

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.
Check the WaterSafe registerAgree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
