Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 18 years on the register also points to an established business rather than a brand-new one.

Verified by Checkatrade
Adam has carried out a complete refurbishment of my downstairs cloakroom, removing the existing fittings and tiles. I’m really pleased with the finished result. He turns up promptly, says what he says he’s going to do and all to a high standard. He’s a tidy worker and clears up after himself each day. He’s also a really nice guy. I’d highly recommend.
Verified by CheckatradeFull bathroom renovation
Adam was great! He was professional, stuck to the pricing and went above and beyond. He was incredibly detailed and offered up finer little touches that would finish off the look of our bathroom. Adam is the best tradesman we have found in London and can’t wait to work with him on our next project!
Verified by CheckatradeRipping out and fitting a new bathroom
Adam was great from start to finish. Quick and clear communication, nice friendly manner and gave good advice on things we were uncertain about. Work was carried out effectively and to a very high standard. We couldn’t be happier with the whole experience and wouldn’t think twice about recommending him if we were asked.

Adam was absolutely brilliant. He was punctual and always willing to help. He was reasonable with his pricing. His work is very impressive too. I have already thought about using his service for a bathroom later this year.

Adam did a great job and delivered exactly on what I wanted at a really reasonable and affordable cost. Over two visits he replaced and updated new glass bath screens, new sink fittings/taps and full replacement of a radiator which included lifting floorboards, moving pipework, tiling and making it all up to a great standard. He helped advise on correct products to buy, including additional necessary valves, and suggested items to improve overall look. Otherwise, super personable, friendly and ill definitely rebook for any future plumbing work!
Verified by Checkatrade
Adam provided a detailed quote following a site visit. Communications were always quick and good. When it came to the works Adam was careful to protect the rest of the house, he provided whatsapp photo and video updates each day and was very helpful with collecting alternative materials when one of our deliveries was delayed. Would highly recommend him. Thanks Adam!

Thank you Adam & G&B for our beautiful bathroom. Completed before schedule, Adam kept us informed and updated through the whole process, very accommodating to our requests and changes along the way. Always cleaned up and left house spotless at end of the day & easy to talk to. Highly recommended! Thanks again Adam.

Adam installed a shower screen and replaced old sealant around the bathroom. Adam was friendly, efficient and reliable and he was very informative about bathroom installation ideas and solutions going forward. 10/10, would definitely recommend and use again!
Verified by CheckatradeEn-suite replacement
Third time we had used the services of this company and profoundly pleased with the results every time. Tired-1970’s replacement done efficiently on time including an emergency fix for two safety related issues found underneath floorboards. Cannot recommend highly enough.
Verified by CheckatradeBathroom fit out
James and his partner did work very hard. But there has been some leaking incidents. Also our ceiling fell down on Monday and i couldn’t get hold of James. Hopefully he can give me a call to take a look. Happy to pay but i heard nothing back from him.
Verified by Checkatrade
Adam has done various jobs in my flat ranging from plumbing to tiling. Each time the result was marvellous and he was pleasant to deal with. From installing a new sink cabinet, taps and bathpanel to putting tiles in the bathroom and kitchen. Adam has done all work to the highest standard and with care for the final result. I highly recommend Adam and G&B plumbing and heating. From my experience he is a safe pair of hands.

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.
