What our customers are saying...

"I LOOK FORWARD TO USING FOR MANY YEARS TO COME"

"Danny is a honest and professional Tradesman, he has an outstanding work ethic, with huge amount of passion to deliver an outstanding end result, good communication throughout. He kept me in the loop from quotation to commissioning, sourced all the parts at honest prices no ridiculous mark-ups, cleaned up afterwards, and his pipework is so neat and tidy, Honestly couldn't recommend enough. I look forward to using DM Plumbing & Heating for many years to come."

"CANNOT RECOMMEND THIS COMPANY ENOUGH"

"I can’t recommend Danny and his company enough. Really nice guy and very knowledgeable. I needed a new boiler and the radiators flushed through. Danny arranged for his employee Jude to complete the work required which he did efficiently, tidily and kept me informed of what was happening throughout the day. Danny called me later on to check that everything went ok with the work completed and I was happy to tell him how pleased I am to have a lovely warm, toasty house again."

"THE MOST RELIABLE TRADES PERSON I HAVE USED"

"Danny was recommended as someone to rely and trust. He was absolutely by far the most reliable trades person I have used. He kept his word to when he would complete the job/turn up. I had incorrectly given him the wrong problem and he let me know and sorted it without any issues at all. He will be recommended to anyone who needs a plumber. Thanks once again for turning up and completing the work when you said you would which never happens nowadays."

"GREAT LOCAL PLUMBER, RESPECTFUL AND EFFICIENT"

"Great local plumber, respectful and efficient. Fixed the job that needed doing and made sure everything else was all in order before leaving. If you want a plumber who's going to turn up on time and fix the problem Danny is your man."
