I recently had a boiler installed/serviced by Narmis Boilers, and I couldn’t be happier with the experience. From the initial consultation to the final check, the team was professional, knowledgeable, and respectful of my home. The new boiler is working perfectly, and I’ve already noticed improvements in both heating performance and energy efficiency. I now feel confident going into winter knowing everything is running safely and smoothly. Not only did we have a Boiler change we got Air conditioning unit installed which lets out hot and cold air.

Outstanding and Reliable Service – Highly Recommended I have used Narmis Boilers on several occasions and have always been thoroughly impressed with their prompt and professional service. They are my go-to company for any boiler-related issues. Back in December, during the particularly harsh snowfall, my boiler failed, leaving me without heating or hot water. Despite the severe weather conditions, Narmis Boilers responded immediately and attended the same day. Their engineer quickly identified the fault and had everything up and running in no time, restoring heating and hot water just when it was needed most. More recently, I needed a new boiler and sought their advice. As always, they were incredibly knowledgeable and guided me through the best options for my home. The installation process was smooth, efficient, and carried out to a very high standard. Everything was completed on time and with minimal disruption, just before I was due to have guests stay. Their service has always been fast, dependable, and of the highest quality. I wouldn’t hesitate to recommend Narmis Boilers to anyone in need of a trustworthy and responsive heating specialist.
