Excellent Service

At 6pm we noticed that the central heating wasn't coming on, although we still had hot water. Contacted our plumber, who in turn contacted Declan from Boiler Upgrade on our behalf. Declan arrived the next morning as promised, within 20 minutes, he had diagnosed the issue and happened to have the part on his van. All fitted and heating working as it should.
Excellent service, polite, prompt and knowledgeable. Would definitely recommend.

Central heating radiator issues

Declan from Boiler Upgrade was recommended to me by a friend. I was having issues with air locks in my central heating radiators which I could not remove by normal bleeding of the radiators involved. Declan was able to give me an appointment within two days of my phone call. On arrival he quickly diagnosed what was wrong, explained to me what had happened and sorted out the issue. I have lived in my bungalow for over 2.5 years and this is now the best my radiators have ever worked!! Thank you Declan.

My heating stopped working

My heating stopped working, so I contacted Declan, and he came out the same day to fix the problem. He is always courteous and does his best to fit me in whenever I need help. Fantastic service as always—highly recommended!

Excellent Service, highly recommended

Declan visited us at short notice for an oil boiler issue and was thoroughly professional, communicated clearly and gave great advice during his visit, as well as a repaired boiler and tank. Highly recommended.

Kitchen Renovation

We used Boiler Upgrade as part of our kitchen renovation, through our kitchen supplier. Their engineer arrived very promptly, was helpful, efficient and friendly. His work was carried out in line with an agreed schedule of works and to a good standard. We wouldn’t hesitate to use this contractor again.

Boiler upgrade are my company of choice

Boiler upgrade are my company of choice. I use them for servicing my boiler. However I called them out as it had suddenly stopped working. Declan came out on a Saturday and stayed until he fixed the issue. This issue was difficult to find but he did it. I would always recommend boiler upgrade.
