Commercial property campaigns often move quickly. Photography, listing copy, brochures, building banners and expressions of interest may all be prepared while legal, leasing and technical information is still being assembled.

For disclosure-affected office space, however, the Building Energy Efficiency Certificate should not be treated as an item that can be added after the campaign has launched. A current BEEC must be registered before the office space is advertised or offered to the market, and its NABERS Energy for Offices rating must be included in the advertising.

This guide focuses specifically on the checks commercial property agents, owners and asset managers should complete before publication. For the wider explanation of BEECs, Tenancy Lighting Assessments, NABERS and the Commercial Building Disclosure framework, visit the TLA and BEEC Knowledge Hub.
