10 General Plumbing
Posted 4 days ago
Finally someone who actually knows what they’re doing
Adam and Kirsty are simply the best — first call, every time, no question. Third engineers in for persistently low water pressure. First to actually fix it. Diagnosed the root cause in 15 minutes flat — something two other companies AND the developer’s own engineers had missed across multiple visits. Came fully equipped, kept me in the loop, fixed the main issue AND helped with a secondary one on the same visit. Big-name plumbing companies are a waste of time and money. AZ Plumbing are the real deal. Just call them.Job location: EC1V10 Gas Central Heating Servicing / Repair

Fixing plumbing problems
Adam at AZ has helped me with several domestic plumbing issues in recent years. He's the best I've used: straightforward, honest and highly skilled in his trade. He takes the time to clearly explain the diagnosis and solution in an understandable way. Also: he is always on time, thoughtful and friendly which goes a long way. I can't recommend Adam highly enough to anyone in need of a plumberVerified reviewerJob location: N510 Gas Boiler Servicing / Repair

Gas safety cert and boiler service
Adam was prompt responding to my enquiry and turning up at the appointment time. He immediately got on with the jobs: a gas safety check and servicing the combi-boiler. He was very thorough in his work, and patiently and clearly answered my queries. He also tidied up after the job was finished. Adam was polite, friendly, knowledgeable, and professional. He was clear up front about his rates, which he publishes on his website. I was impressed with his work and happy to have him back to do a second job for me. Will use again next for next year's boiler service.Verified reviewerJob location: WC1H10 Gas Safety Checks - CP12

Resolving issues after previous contractor's shoddy workmanship
AZ Plumbing was brought in to resolve several major problems. There were several visits to the house, but Adam put it all to rights. He's very knowledgeable, thorough and professional. No bodged work here! An excellent plumber/heating engineer. I wouldn't hesitate to recommend him.Verified reviewerJob location: N110 Gas Boiler Servicing / Repair

Boiler service and fixed gas leaking
Adam is amazing. He is professional, thorough, fast and reliable. He corrected the installation mistakes of the boiler, also found out a gas leak in the house which is life saving. He does things in a very proper way and he is completely trustworthy.Verified reviewerJob location: N1
