Why join us?


B&ES membership is open to UK firms engaged in the design, installation, commissioning and/or maintenance of heating, ventilating, refrigeration, air conditioning, ductwork, plumbing, facilities services and energy management systems.

All B&ES members are subject to regular third-party competence assessment. Currently, BESCA administers this process using the services of BM TRADA a recognised certification body with a sound track record in the construction industry.

Potential members must undergo independent competence assessment prior to admission - and this complete inspection will take place for the first two years thereafter. Assessment is then repeated for all members every year with a full site inspection at least every three years.
The assessment will cover commercial capability – including such matters as administrative and business systems, financial and training records, insurance arrangements, and health and safety, environmental and equal opportunities policies and their application.
Additionally, it is designed to evaluate technical competence. This takes place on-site and involves the inspection of work in progress against a broad range of standards, devised and simplified by the B&ES in collaboration with the Building Services Research and Information Association (BSRIA).

  • are assisted in qualifying for membership of a Competent Persons scheme operated by Building Engineering Services Competence Accreditation Ltd (BESCA), and so are able to self-certify work they carry out in relation to Parts F,G J and L of the Building Regulations;
  • are pre-qualified for registration under the Government-inspired TrustMark scheme in England and Wales, and other partners to the SSIP because the core H&S checks have been satisfied under 'deemed to satisfy' arrangements;
