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" > Source: Anonymous (5.0, via Checkatrade) > "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." > Source: Anonymous (5.0, via Checkatrade) ## Trades Plumber, Gas Engineer ## Services they list _Listed on public sources or the business's own website; check directly that they cover your job before you book:_ - Air Source Heat Pump Installation - ASHP - Air Source Heat Pump Servicing / Repair - ASHP - Bathroom & Kitchen Plumbing - Blocked Baths - Blocked Sinks - Blocked Toilets - Gas Boiler Installation - Gas Boiler Servicing / Repair - Gas Central Heating Installation - Gas Central Heating Servicing / Repair - Gas Cooker Installation - Gas Safety Checks - CP12 ## Areas covered _Towns and areas this trader lists serving.

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. - For the water-regulations side of plumbing, a WaterSafe-approved plumber is vetted, qualified to the water regulations and insured. You can check yours or find one free at watersafe.org.uk. - Confirm they cover your area and can actually come out in your timeframe before anything else. ## Contact - Phone: 07307 263091 - Website: https://azplumbingcontractors.co.uk/ --- Source: MyTrustedTraders, https://mytrustedtraders.com/traders/az-plumbing-contractors-ltd-2 Real public evidence only: every figure traces to a named source, and reviews are cross-checked across 2 review sources.
