He fixed the problem that I had had with a non-functioning heated towel-rail in the bathroom that had worked until the revision of my central heating system to include a Central Heating Management System by an outfit that has since ceased trading. The system has separate zones for upstairs and downstairs and the towel-rail is plumbed in parallel with the heating coil of the hot-water tank. It took more than one visit to sort out the problem and then get the system balanced between the radiator flow and the towel-rail flow.

DA Heating and Plumbing relocated a new gas boiler for me. The work involved removing a back boiler located in the chimney breast, removing the hot water cylinder from the airing cupboard and removing the cold water tank and header tank in the loft. They then installed a new boiler and system in the loft. In addition I had a radiator replaced in the bathroom. I found Dave Armstrong to be a very professional trader. When carrying out extensive work Dave and Matt were careful and considerate in my home. They checked in with me regularly, making sure the work was as I wanted. The work was completed to a very high standard and my home was left clean as they finished. They made extensive work stress free. Dave and Matt are nice guys and I was comfortable having them working in my home. I would be very happy to recommend DA Heating and Plumbing to anyone considering heating or plumbing work.

I found their details on Google and phoned for a quote. The service was exceptional from start to finish, they were quick to provide me with a quote, accommodating to book the work in and the work was carried out in a professional manner. Communication was excellent, appointment reminders were sent and a text confirmed an engineer was on their way. Would definitely use again and would highly recommend.

We used DA Gas to shut off the gas supply to our cooker as we are installing a fully electric cooker instead. The receptionist who booked the appointment was lovely, very helpful and extremely pleasant. Daniel who came round to do the work was lovely. He worked very efficiently, made sure that we were happy with everything he was doing, was very knowledgeable and left the house clean and tidy. I recommend this company and would use them again. Thank you DA Gas!

I had my boiler serviced & a gas safety certificate to prepare for my house to be sold. I found the company really friendly & approachable when booking the appointment. Then on the appointment day, the engineer was on time & did a professional & thorough job. He was friendly & explained everything really well. I've recommended them for my parents as I was particularly impressed.

Boiler service
From the moment you talk with the officer manager Michelle to book the job in and then she calls after the job was done to check your satisfaction of the job is excellent. The boiler engineer was friendly, knowledgeable and a very helpful person. First class service all round wouldn’t hesitate recommending them. Third year on the trot I’ve used them.

Underfloor Heating Re-pipe

My son-in-law had an issue with the flowmeters on his underfloor heating and I had no hesitation calling DA GAS as I have used them before. The problem was diagnosed as the temperature control valve being incorrectly piped by the original installer. The pipes were reconfigured with the minimum of fuss and the system now operates perfectly.

I needed a plumber to investigate what I thought was an underfloor leak in my ground floor toilet. Contacted DA Gas Heating & Plumbing Ltd as a result of reading reviews on Which Trusted Trader. Dave agreed to call in later the same day to assess the job. He turned up on timed and quickly identified a much simpler problem of a leaking shut off valve of the toilet cistern, which I had missed. He replaced the faulty valve there and then, at a very reasonable cost. Throughout he was very professional and friendly. I was so impressed that I shall shortly be arranging for him to return to service my central heating boiler.

Thank you to Dave, Michelle and Kane for again being spot on with servicing my boiler, this time I had a few more jobs a leaky rad and a new shower hose all completed by engineer Kane in the time that I was told it would be done, Kane even gave me a courtesy call once he had finished the job to tell me the work had been carried out and when I returned home no mess was left behind. No need to look any further then DA Gas. Thanks again I’m looking forward to having my en-suite renovated later on in the year.

DA Gas replace two bathroom taps and an isolator valve for us. Due to a cancellation, the job was completed a couple of hours after I booked it. The young man who attended was very polite and respectful and completed the work to our complete satisfaction. There was a small misunderstanding regarding the price quoted as we supplied the taps, so were initially overquoted. However, Michelle from the office called me later to explain and reduced the price, even though I had accepted the original quote and would have been none the wiser. I really admired and respected this honesty.

Superb communications to book appointment, and text message to confirm engineer on their way. Invoicing and aftercare spot on. Plumber worked our problem, and new parts needed to be ordered. Second appointment to fit new parts very quick. Any company can have problems. It is how the company deal with the problem that is important. In this respect his company is exceptional. One is in contact with a central office - not trying to contact a plumber who may be working at another destination.
