NABERS UK Energy for Office ratings recognised under the UK Net Zero Buildings Standard

The NABERS UK Energy for Office ratings, certified by CIBSE and administered through its wholly owned subsidiary CIBSE Certification, may now meet the operational energy requirements of the UK Net Zero Buildings Standard (UKNZCBS), as defined in Annex C of the Standard.

Since taking on the role of NABERS UK administrator in 2024, CIBSE has worked closely with NABERS and the Better Buildings Partnership (BBP) to drive the decarbonisation of buildings through the rapidly expanding NABERS UK Energy for Office scheme. This recognition marks a significant milestone for the scheme, reinforcing its role as a trusted benchmark for operational energy performance.

Over the past months, the CIBSE Certification team and the UKNZCBS team have collaborated to ensure NABERS UK certified ratings align with the operational requirements of the Standard. Their joint efforts have been successful, ensuring that NABERS UK Energy for Office certifications – including the prestigious 4.5 star rating – may now be used to demonstrate compliance with UKNZCBS operational energy requirements for existing offices.

Kieran O’Brien, Director of CIBSE Certification, said: “We are thrilled that NABERS UK Energy for Office ratings are recognised under the UK Net Zero Buildings Standard. This demonstrates the credibility and robustness of the scheme, providing building owners, occupiers and investors with confidence that their operational energy performance meets one of the highest sustainability standards in the UK. It’s another step forward in CIBSE’s mission to support the decarbonisation of buildings and a net-zero built environment.”
