I had a sizeable job done at my house, full modernisation of heating system, tank, boiler, cylinder and controls. From the outset, everything went exceptionally well. Professional, confident,experienced crew. Worked long days to ensure job would be completed efficiently with minimum distruption. Cleaned up completely when they had finished. Have already been recommending Declan and the crew to others. Im confident that after sales attention will be just as good if l needed it.

The DS Gas-Oil Services team were excellent to work with. My old Gas Boiler Heating System was very inefficient, we were filling the external “Bulk Gas Tank” over 3 times a year costing us thousands. Right from the start Declan worked with us in discussing our needs and reviewed the history of our heating system. Together we chose a “New” Viessmann Gas-Fired Wall-Mounted Condensing Boiler with a  3 Zone Climote heating control system. The team installing the system were quick, precise and neat. The completed Heating System install was fully commissioned to a high standard and walked through with us by Declan on completion. It has now been more than a year since we having the system upgraded and our heating bills have been cut in half. At the time of the upgrade we took advantage of the Government Home Energy Grant, Declan and his team assisted us every step of the way is availing of the scheme. With the excellent service, professional install, and proven cost savings within the year, calling the DS Gas-Oil Services team was one of the best investments we have ever done for our home. If you are looking for an excellent way to reduce your yearly heating bills and add value to your home give the DS Gas-Oil Services a call.

Declan, Ken and the electrician (Liam) were model professionals. They explained clearly what they intended to do, they arrived on time and carried out the work neatly with a minimum of fuss. The electrician ran through the complete operation of the system with me and I am really pleased with the upgraded water/heating electronics and the new boiler. Regards and many thanks to all.

The plumber and electrician who did the installation were very efficient, friendly and very clean workers. Declan came back after the job was finished to check all was okay and spent time ensuring the paperwork for the grant was correct and completed correctly.

From the moment that Declan Smith arrived to do the site survey, right through the installation work carried out by his team and Declan’s follow up call to ensure that the work carried out by his team and had been carried out properly, we were delighted with the professionalism and quality of work carried out. Declan was extremely helpful in assisting us in deciding what was the best type of installation for us and was able to answer all of our questions. Once we had decided to go ahead, he gave us a firm date and time for the work and told us how long it would take. We were a bit worried that there would be major disruption to the household while this work was being carried out but our fears were groundless. Declan’s team turned up at the arranged time on both days and were well within the schedule they had given us when the work was completed. In between, they carried out all work, including groundwork and removal of the old system and installation and testing of the new boiler with great care, explaining patiently to us all the stages of the process. When they were finished, we were given thorough instructions about the boiler and its controls. When they were gone, it was hard to see where work had been carried out, so carefully had they cleaned up after themselves. the only real clue that they had been there was the warm and cosy home that they left behind. I would have absolutely no hesitation in recommending them Declan Smith to anyone who was interesting in having a Calor LPG system installed.
