British office ratings to get a 'prime' tier overhaul, focusing on sustainability and health.

The British Council of Offices (BCO) plans a major overhaul of its office rating system, introducing a new "prime" tier for the highest quality spaces. This move aims to better reflect office quality, as the current three-tier system (grades A to C) is deemed outdated. The BCO is consulting on changes that would measure aspects like sustainability and health, to provide clarity for investors and improve industry standards.
