Our History

Founded in 1949 by Sidney Inwood Sealy, S I Sealy and Associates has grown over the intervening years into one of the foremost, and most respected, Building Service Engineering Consultants in the North of England.

In 1991, the Practice became a Private Limited Company with the original Practice Partners becoming Directors. During the past few years, further Directors have been introduced to the Practice to further the continuing expansion and development of the Practice at home and internationally.

With the rapid development in technology over the past few years, our engineers continually develop and expand their knowledge of new technology and techniques to provide clients with an up to date service, making full use of both latest and well established technology and practices, incorporating an accredited Quality Assurance system.
