“Punctual and thorough boiler service.”

Kat LCheckatrade5.0 rating

“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 plumber”

AnonymousCheckatrade5.0 rating

“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.”

Adam was very responsive and managed to squeeze me into his schedule at the last minute (not something that can be taken for granted in central London). He resolved the issue quickly and was also able to provide practical advice on how to avoid the problem in the future, while also offering suggestions about shorter term fixes and longer term solutions. A very friendly and professional approach. Highly recommended.

Verified by CheckatradeBoiler service and fixed underfloor heating.

Adam serviced our boiler and fixed a problem with our underfloor heating. He immediately identified some dangerous problems with our boiler (Co2 and gas pressure) and called out Cadent to fix it promptly. Highly professional, knowledgable, considerate and thorough in what he does, respectful of our property (put on overshoes every time he came into our house). He even found a black pipe to replace a part of our flue to match other pipework in place. I highly recommend !!

Called out Adam due to a leaking radiator. He quickly diagnosed and fixed the issue and left everything neat and tidy. He also gave some good advice about our heating system! Would highly recommend!

We have had AZPC come out twice to help with plumbing issues and both times Adam has been excellent. Efficient, knowledgeable and exceptional reasonable on cost; he fixed both issues with minimal fuss. For our bathroom leak we had multiple other plumbers come and but AZPC were the first to actually identify the problem and sort it rather than just have a brief scan of the room and say we need a complete refit. Would absolutely recommend.

Verified by CheckatradeIdentifying the problem with the taps and fitting new ones

Adam was extremely professional, punctual and tried to get the best solution taking the cost into account. All the communication was clear and he helped me source some parts and gave me very clear instructions. The final result was very good. I have relied on Adam for a number of plumbing jobs now and I have been consistently happy with his approach and the result. He has the interests of the client at heart.

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 register
Agree 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.
