Above and beyond
Tim and crew did a fabulous job fitting new central heating and the plumbing for the new kitchen. They had to deal with difficult builders but were very professional. They went above and beyond to help me get the extension finished. Think it was out of pity from problem builders! No hesitation in recommending them. Quality work, decent price.

Reliable and professional
I have used Tim and his company TDC for a number of years now. From gas leaks to plumbing. Last month, Tim's team attended to repair a leaking garden pipe. The work was carried out promptly and professionally, and everything was left clean and tidy afterwards. Communication was straightforward and the service was reliable. I would be happy to use their services again. Thank you

The best plumbers in town!
Having experienced a third leak in our property, TDC had no hesitation in coming out to rectify the problem. We’ve now used TDC several times with ongoing maintenance & will continue to do so! From the outset, their staff are approachable, polite & friendly! Their knowledge about plumbing is second to none, whilst listening to the customer! They work extremely hard, barely stopping for lunch! Their prices are reasonable. More importantly, they respected our home using floor covers etc. We’ll have no hesitation in recommending TDC to family & friends for ALL our plumbing needs! Hence the title … The best plumbers in town! Thanx u TDC Plumbing & Heating! ☺️

Considerate Team from start to finish
I engaged TDC Plumbing following a bad experience with another company. Team set to put things right. Without exception the guys were calm, considerate, informative and I was left feeling confident that I would use them again in the future. I’d have no problem recommending them. Thank you.

"Fantastic job replacing the leaking valves in my radiator, draining, refilling the whole central heating system, Theo was professional, knew exactly what he was doing, Great communication and very tidy workmanship. Would definitely use again....no mess left behind...spotlessly clean. 5 stars!"
Verified by Checkatrade
I had 2 showers - one that was running too hot and one that was running too cold. Theo explained what the issues could be on the phone and it was agreed that new showers would be needed. He ordered them straight away and came out the next day to sort it. He was really friendly, explained the issues clearly and was tidy. Would highly recommend!
Theo sounded scary when I first spoke to him. But I couldn't be more wrong. Hes a gentleman, professional, friendly and reliable. I am very happy with the advice he gave and the pump installation. You can see he takes pride in his work as he is just as restless as you until the job is done and looks good.

Excellent communication, people and work undertaken
Ricky and Josh fitted a new kitchen mixer tap for me. They were extremely friendly and completed the job quickly and tidily to a high standard. Prior to the appointment, I was kept well informed, being sent confirmation and then a reminder for the upcoming appointment.

A plumber you would be confident to recommend to your best friend
Theo responded promptly to my enquiry to carry out the work I required. He gave me an acceptable costing and a date the work could be carried out. He arrived to do the work on the agreed date. Was professional, knowledgeable and friendly. He explained what he was doing and carried out the work to a high standard in a clean and tidy manner. He respected my property. I wouldn’t hesitate to recommend him or his company.

Theo was great from start to finish. Responded quickly and came within 48 hours to quote for the job. We had a pump fitted and new shower, taps and kitchen sink installed.

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.
