CIBSE’s membership is a worldwide network of building services professionals. There are currently over 21,000 members in nearly 100 countries.

Through our network of 20 volunteer led Regions we seek to connect, inform and inspire our members and the wider communities in which they work and live.


You are automatically enrolled into a region when you create an account. To update your region you will need to update your details by visiting and updating your Profile with your address change. You can also opt-in to receive communications from other regions from your Profile.


Our Regions are run by committees; teams of volunteers that are elected annually at each region's Annual General Meeting. CIBSE members wishing to become a part of the committee can put their name forward for election when the date is announced to the Region. Committees can co-opt members at any point throughout the year. The regional chairs sit on the CIBSE Council.


You can email [email protected] with any questions.
