From humble beginnings as a one man band in 1984, then called Anthony Owen Services. We had a change of name in 1991 to reflect our commitment to Energy Efficiency, and we became AOS Energy Efficient Heating Systems Limited.

Since 1984 AOS has continued to grow, developing existing staff and engineers through it's training programme. We have developed a culture of customer first where we relentlessly monitor customer satisfaction and quality of work.

We are still a family orientated business based in Cheshunt, Herts. Primarily our work is plumbing, heating and electrical work within the domestic market.

We are very proud to be in the position of competing with the National Companies, but by being a regionally based and family orientated company we can offer that personal touch.

Our goals for the future are to develop new products and services, and to provide an even more comprehehsive service to our customers. This website is at the forefront of that commitment, and will provide new and existing customers with the very latest advice and information.
