"I have had a heating system including a Vaillant boiler, Megaflo and underfloor heating installed by DGN GAS. A very professional service and am extremely happy. I especially like the after sales care. Would highly recommend."
"Absolutely wonderful service. 100% reliable, transparent and competitive. A company you can trust and feel in safe hands with."
"I had a new hot water cylinder fitted. DGN GAS arrived the next day, carried out diagnostics and resolved the problem. Everything came to a very fair price. I would highly recommend DGN for all my plumbing needs."
"Have used DGN GAS a few times now. They installed a boiler at my parent's house and do the annual boiler servicing. I had a boiler and underfloor heating installed at my house too. Very happy with everything."
"DGN Gas installed a new Baxi Boiler for me in February 2021, they have serviced and carried out the landlord gas safety inspections ever since. Excellent professional service. Extremely satisfied."
