WHAT OUR CUSTOMERS SAY

Our old boiler stopped working and Kieran came round very quickly to have a look. Boiler was 19 years old and in bad condition and not worth fixing up. So 4 days later, new boiler was installed with Google Nest controls. Absolutely fantastic advice and workmanship from Kieran and nothing was too much trouble. Very happy indeed and would recommend Deehan Boiler Services to anyone, thank you!


Colin Sortwell

Even though I contacted him late in the day, he was around to the house within 45 minutes and sorted the problem. Greatly appreciate this. Thank you

''A big THANKS to Kieran, who came out this afternoon and fixed my Mum's central heating when her usual plumber couldn't. Would highly recommend and will definitely be using Kieran from now on. Thanks again Kieran.''


Aileen Caughey

Great service from these guys today quick, clean and tidy. Great work done relocating and fitting a brand new oil boiler. Couldnt have done enough triple checking everything works and making sure we know how to use the new features. Definitely recommended these guys.


Patrick Rice-Early

DBS did an excellent job installing a new boiler for me today. Kieran and his colleague arrived on time, worked exceptionally hard in spite of the awful weather. They were friendly, polite and professional. They took away the old boiler house, boiler, flue etc and did a great job of tidying everything up. Kieran ensured that every thing was working to my satisfaction and did all the necessary paperwork before he left.


This was the first time I had used this company and couldn’t be more pleased. Thank you Kieran.
