About Us

A1 is a family business, founded in 2000 by Steve Mills, who, during his early career in loft conversion construction, recognised that many individuals within the industry operated without due care and consideration for clients. Hence A1 was established with the intention of guaranteeing the highest level of services and excellence in the finished product. Our extensive portfolio of satisfied clients reflects our dedication in providing a first class service.
