BESA has evolved throughout the years to reflect the growing needs of our members and encompass all of the specialist services available within the built environment.

Established in 1904, BESA has been known by several names throughout its history, most notably as the Heating and Ventilating Contractors’ Association (HVCA). Now trading as BESA, our primary focus is to support and serve our members active in the design, installation, commissioning, maintenance, control and management of engineering systems and services in buildings.

We are a membership organisation. Our mission is to act as our member’s voice, representing the best interests of firms active within the built environment at a regional and national level. Our members range from the smallest enterprises to the largest organisations within industry, we offer specialist support services, training courses and advice that is tailored to meet their individual requirements.

Our headquarters are in London, but we are active throughout the UK - with a longstanding presence in Scotland, Wales and Northern Ireland. Our nationwide and regional presence is facilitated by our dedicated membership team who build strong working relationships with each of our members, enabling networking and sharing of best practice, business opportunities and advice on all local and national developments.
