Building safety has never been more important. An essential part of being able to ensure our built environment is safe for all communities is to ensure they are designed, built, and maintained to the correct standards by competent and compliant firms. As the trade association for the mechanical building engineering services sector, we represent firms committed to building safely.

Members of BESA must meet industry compliance, regulatory, legal, and technical requirements through assessment of their competence.  This guarantees clients' peace of mind that contractors delivering their projects are technically competent, have a skilled workforce and deliver high-quality services.
