Terence hillock

Great Job

I would highly recommend DG Gas Safety. We were having problems with our old boiler and got in touch with Glen through one of his team. Glen had a look at the job and the best way to complete it. He gave a really good price for the work and that's what was paid. The guys who did the work were excellent. They arrived on time, did a great job and left the place clean and tidy. Great customer service overall.

William Mcbride

Job well done

Had DG gas services out today having only phoned them the day before. Glen was amazing man.
Serviced my fire, not to say that it's as old as the hills and not been Serviced or cleaned in over 15 years.
What a fantastic job he did . Glen was friendly and helpful. Cleaned up the mess, totally dismantled the fire to reach the back boiler. Cleaned everything, tested everything with enjoyment doing his job.
I would recommend this company 100% too anyone.
Job well done

Stephen Laughlin

Fully Recommend

The guys at DG designed and fitted a complete heating system in our new store. They listened to our requirements and not only met them, but also suggested a few useful ideas such as including a Hive smart system which we LOVE. The work was carried out in a day and the place spotless. We at Beyond Performance 4x4 would have no hesitation in recommending DG Gas Safety.

Donal Hannaway

A very professional and reliable company

DG Gas Safety replaced my gas boiler. The boiler heats the property and provides hot water. The boiler broke down and DG Gas Safety prioritised the work immediately knowing that a family was dependant on the service. Excellent work and I will use DG Gas Safety for the annual maintenance service. A very professional and reliable company and I would recommend them to anyone. Thank you DG Gas Safety.

Fantastic Job

\Would highly recommend using DG. Lovely people, very professional and did a great job. They didnt have the most easy jobs to do, and took them longer than expected, moving boiler and pipes but did it in there stride. Everything was done neat and tidy and they cleaned everything before they left. It was fantastic. We have had some terrible workmen lately but these guys where brill. Thankyou
