I can honestly say this experience has been amazing. After hearing so many horror stories about boiler installations I was anxious. From the very beginning, Glen and Nicole were so helpful, informative, and knowledgeable. The installation took place with Nicole calling to ensure all was well, she also called to ensure I was happy and had no issues at the end of the process. The engineer was so good, he did not stop working until everything was complete and all tested. I cannot thank the team enough and would recommend it to my family and friends.
