Expand Group followed up promptly, I had a visit the next day to inspect the issue, advice and a quote was provided. When I did a bit of market research the quote was very competitive and I really liked their professionalism and friendly approach. I accepted the quote, and I was very happy with the service and product installed. This is local company which is important to me as a consumer. The guys cleaned up after themselves and left my house safer (and warmer) than it was when they got here! I will be passing their details on to my friends and would not hesitate to recommend them.
