10/10 · New Air Conditioning Installed
"From my first enquiry to completion of works I found them to be very courteous, hard working and competitively priced. Dan carried out a full survey and gave a cost breakdown for works. A date was booked and the guys turned up on time and work was completed within the given timescale. They were very polite and tidy and even vacuumed after completion. I am so happy with my new hot/cold air conditioning unit which will enable me to work comfortably from home and sleep at night. They even sorted my dripping tap free of charge! I would highly recommend DM Heating and Cooling."

"I had a new combi boiler installed and had my old one removed. Excellent service and a very productive team. They were helpful with boiler and thermostat advice and quick to reply. I would highly recommend their services."

"Boiler repair after using another company that could not fix the issue. Dean was amazing. After resolving the issue with no parts cost. I'd recommend Dean from DM Plumbing."
10/10 · Gas central heating installation
"Dan and his team arrived at the given time and carried out the replacement of my boiler and all radiators in a speedy and efficient manner.

I was very happy with the outcome for a very competitive price and will gladly use them again and happily recommend them."
10/10 · Gas central heating installation
