Bittersweet honour for air quality champion

Air quality and child health campaigner Rosamund Adoo-Kissi-Debrah has been made a CBE for services to public health in the King’s New Year Honours. 

She described the award as “bittersweet” because her campaigning was prompted by the death of her nine-year-old daughter Ella, who is the first person in the UK to have air pollution stated on her death certificate. 

“It is an absolute honour and recognition for the campaign [but] children are still dying, and my ambition is to keep on campaigning so that no other parent has to experience what I went through,” she said. 

MPs are currently debating her proposed Clean Air (Human Rights) Bill – also known as ‘Ella’s Law – which has already received approval from the House of Lords and the London Assembly.  

The new law would introduce specific responsibilities for building operators to meet indoor air quality (IAQ) targets in line with World Health Organisation (WHO) guidance and Kissi-Debrah has become a prominent voice in the push to improve standards of ventilation in buildings through her work with the Building Engineering Services Association (BESA).

BESA Academy wins digital transformation award 

The Building Engineering Services Association (BESA) Academy has been awarded a prestigious Association Excellence Award (AEA).

The online technical training service came out top in the crowded Digital Transformation category and was recognised by the judging panel because of its rapid response to increased industry demands for digital services during the Covid-19 pandemic. 

The Association completely transformed its training provision in just four months to support the sector during lockdowns.

The AEA judges recognised the importance of this work in supporting the building services sector through a critical period and congratulated BESA for its speed and breadth of response during a celebratory awards lunch at the Kia Oval, London last week.

The AEA Awards were set up to celebrate and encourage the vital work that trade bodies, professional organisations and chartered institutions do for their members to ensure their voices are heard and their causes are championed.

BESA had already planned to take more of its training provision online but accelerated the programme at the start of the Covid emergency and the BESA Academy was launched in August 2020 – it now has more than 9,300 users. 

About Us

The Building Engineering Services Association (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 a proud heritage and 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 the 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, as well as eight regional offices. Our regional presence is facilitated by a team of dedicated Association Managers 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.

Specialist Groups


The specialist groups within the BESA provide members with an opportunity to address issues and set standards across the disciplines that comprise building engineering services.

- Ventilation The group is committed to maintaining the highest technical, efficiency and safety standards in ductwork manufacture and installation.

- Refrigeration, Air Conditioning & Heat Pumps The group is committed to safeguarding the environment by promoting and improving professionalism in the refrigeration and air conditioning sector.

- Heating & Plumbing Services The group is committed to the delivery of sustainable, energy-efficient heating and plumbing solutions in residential and small commercial buildings.

- Service & Facilities The group is committed to promoting the highest standards in the management and control of engineering services systems and facilities across the built environment.

Specialist Interest Groups


From time to time, special interest groups are formed within the BESA when issues arise that call for particular focus, either for a specific period or on an ongoing basis.

- Ventilation Hygiene – Formed by the Service and Facilities Group, the Ventilation Hygiene Branch was instrumental in the development of the BESA Guide to Good Practice for the Internal Cleanliness of Ventilation Systems (TR19), and continues to focus on topical issues relating to ductwork cleaning.

- Indoor Air Quality – The Indoor Air Quality Strategy Group – membership of which comprises manufacturers and consulting engineers as well as contractors – has been formed to build positive contacts within local and central government and to develop alliances with like-minded organisations.

The Building Engineering Services Association (BESA) has announced the passing of its former president Peter Hoyle at the age of 76 with great sadness.

Hoyle was the first president of the Association since the Second World War to serve two consecutive terms following his election in 2000. He then became only the sixth person in the history of what was then called the HVCA to be awarded its Distinguished Service Award.

BESA chief executive officer David Frise said only individuals who rendered exceptional levels of service to the Association and its members received this special accolade.

“We refer to it as BESA’s ‘Hall of Fame’ and Peter certainly deserves to be regarded as one of our most outstanding past presidents for his totally dedicated service to both the Association and the industry at large,” he said.

Formerly managing director of Bradford-based Mitton Mechanical Services (now Mitton Group), Hoyle was also president of GCI-UICP, the European umbrella body for the building engineering services sector, and achieved considerable success as the UK’s representative on the international stage.

He served on the HVCA’s Council for more than 20 years and carried out vital work for the benefit of all members through his work on the Membership, Operations, Finance and House committees. He was also a director of the Association’s subsidiary Piper Enterprises and chairman of its training provider Building Engineering Services Training Ltd (BEST).

“He was a totally genuine man who, above all, recognised the value of the people he worked with and the importance of investing in their development,” said Frise. “In his inaugural address, Peter insisted that quality began and ended with people – and that any organisation, business or trade body, could only be as good as the individuals involved.

“Peter Hoyle will be remembered for his kindness and desire to help and support others whether in his business or personal life. We are truly grateful for his long and distinguished service.”
