Great service
Our water softener was acting up. Contacted a couple of traders including one 'Trusted Trader' who did not respond after takeing all details. Other marketed new water softeners with cost up to £1500 without checking if the current kit could be repaired. I contacted Dan. He came one late evening given his busy schedule. Gave the equipment a check, advised me how to monitor if working and to get hold of a water softerenr checking kit from Amszon (cost £3.99). The softener is working fine since ! Dan did not charge ! He said he will invoice if more work is required and also advised further on what replacements to buy if required later.

Will definitely use again
This is the second time we've used Dan and are already in discussion for two more possible jobs. Dan is direct and to the point, something we appreciate greatly but explains all his opinions in a way that we can understand and makes sense. He advises not only what he thinks you should do but also what you don't need to do. His work is tidy and efficient. We had him and his colleague here for 2 days replacing an old lead mains pipe and I never saw them not working! A huge amount of effort went in and we are really pleased with the result. Everything was put back exactly how they found it. Very happy with the whole service and the price and have already recommended him to friends.

Electric shower replacement installation& cabinet repair
Thanks for the excellent work. Daniel explained all the key steps he took when replacing our electric shower and making good. Its working well and we will use him again. Daniel is clearly skilled, hard working and reliable. Daniel very much deserves to be a "Which Trusted Trader".

Bath & Shower fit
We recently had our bath and shower fitted and couldn’t be more pleased. Daniel was professional, reliable, and incredibly knowledgeable, taking the time to explain everything and going above and beyond to find the best solution for our bathroom. His work was completed to a very high standard — he is extremely trustworthy, and we would highly recommend him.

Competent, conscientious and good value
Daniel replaced our broken toilet at short notice. He fixed a number of related plumbing issues whilst he was here. Daniel worked fast and competently, explained clearly what he was doing and the problems he encountered. We are very happy with the standard of Daniel's work and will use him again in the future.

Reliable Gas Pipe Refitting – Thorough, Skilled, and Trustworthy
Dan recently refitted our gas pipes beneath the floorboards, and I couldn’t be more impressed with the quality of his work. He was incredibly thorough from start to finish, carrying out multiple tests and checking every detail to ensure everything was completed safely and to a high standard. His knowledge really stood out — he explained what he was doing at each stage and shared best-practice advice to make sure all the work met current regulations. The quote he provided at the start stayed exactly the same, with no unexpected add-ons, and it was very reasonable compared with others we received. It’s rare to find someone this reliable, transparent, and skilled. I’d highly recommend Dan for any gas work.

Thank goodness we found Dan
We have been struggling for a number of years with recurring issues from the water tank in our rental apartment. The feedback received from the letting agent appointed contractors was often nonsensical or even absurd, and issues just kept on returning. Recently the agent appointed contractors wanted to change the complete water tank due to a suspect heating element! While we have been fed up with the seemingly incompetent contractors appointed by the agent we did find it challenging to find a reliable plumber as we do not live close, luckily we stumbled across the which trusted traders page and noticed Dan was not far away and had great reviews. Lucky for us he had an opening that suited and managed to replaced both the heating elements (for the amount of trouble we decided to just have both replaced). He also managed to sort some other issues at the same time and provided some great pictures to show what has been done and that the heating elements were now both functioning. We can highly recommend Dan and will also keep his contact details for future issues.

Bathroom
Daniel fitted 3 new bathrooms in our property. The works included converting an old bedroom into two bathrooms & an old bathroom into a bedroom. Daniel was very helpful through out the project advising us on design & best materials/wares. The works took longer then anticipated as there were issues with the floor not being level, crumbling walls etc. But Daniel deal with all these issues, was very thorough & kept us informed throughout. Couldn’t be happier with the works & would definitely recommend

Bathroom refit
This is the 3rd time I used Daniel but it was for a complete bathroom refit and also upgrading the flats plumbing and pipework. Daniel is very knowledgable and always gets to the root of problems and then fixes things properly. He is punctual, professional and I would highly recommend him as a trustworthy and very professional plumber and bathroom fitter.

Plumber required
I was looking for a trusted Plumber and found Dan through Which Trusted Traders. I needed a plumbing issue fixed in our shower which Dan very clearly explained what was required and the time it would take. Dan also installed a new shower in our main bathroom. With both jobs, Dan suggested a couple of options before carrying out the work.

Recommend and will use again
Dan was tasked with a few jobs, attached by magnetic filter to the boiler, replacing radiator valves and installing a new dishwasher. He was friendly and considerate as we have young children and pets in the home, communicated clearly at each stage as the magnetic filter and dishwasher wasn’t straightforward with lack of space needed extra plumbing work. He kept the job within the estimated cost and time. Overall would recommend and will use again.

honest and reliable
Dan replaced a shower tap, fixed a shower and a shower rail and replaced mouldy silicon in our bathroom. He came on time, did exactly what he was asked to do and left the place clean. His quote was reasonable and there were no unexpected issues. He gave us some advice on what to do if we would like to carry out more extensive work in the bathroom, which was really appreciated. He was polite, did not waste time on the phone talking to his mates and did not smoke, not even outside our house.

IMPRESSIVE
Prior to quoting for the work I wanted i.e. replacement of 7 very old radiators Daniel very clearly an patiently explained how things would work and offered various suggestions. I was very impressed because he so obviously knew exactly what he was talking about and was very happy to explain things so I could understand. His quotation was very reasonable. Daniel experienced some problems during the fix due to crumbling walls ( 1930’s house) but he persevered and whilst he had to revise the quotation because of the extra work the overall cost was still very good. Daniel was always hard working & very polite. He worked late in order to leave the job each day in an acceptable state. I am hoping to get him back again in to do some work in our bathroom. I have no hesitation at all in recommending Daniel to anyone who needs a plumber.

Hard Working
Daniel is hard working and was requested to complete renovations of one bathroom and one shower room within 2-3 weeks. He delivered that. On top of that he pointed out several cost saving measures and a few good practical advice for bathroom designs. However the finished qualities of sealing and some renovations were rough. Maybe because of rushed jobs. There were leaks in the shower room post renovation and the leak did leave some damages on the wall. He did come back twice to try addressing the snagging and leak issues. Some were caused by the reuse of old shower screen ( not his fault) but others traced to the insufficient sealing of new panels and flooring.

Replace concealed cistern
Very happy with the quality and finish of the bespoke new unit (he even managed to fit my old tiled shelf on top) Daniel provided options and recommendations before and during the build. Some minor additional spending on replacing a pipe connector and buying another board, but for the amount of work completed his bill was very reasonable, especially considering he’d worked late to finish it

Worth checking yourself
Their public evidence comes from a single source. Look them up on another site before deciding.
Verify at the sourceCheck them yourself
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.
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.
