The UK Net Zero Carbon Buildings Standard is set for launch

The UK Net Zero Carbon Buildings Standard is the UK’s first cross-industry standard for net zero carbon aligned buildings. A pilot version was published in 2024 and, following pilot testing in 2025, the full Version 1 is set for launch in March this year.

The UK Net Zero Carbon Buildings Standard is a voluntary standard applicable across new build, existing buildings and retrofits. It was created through unprecedented collaboration within the UK built environment industry, and is backed by building data and science-led modelling.

The free-to-access technical Standard will enable the built environment to robustly prove that built assets align with the UK’s carbon and energy budgets, using an agreed methodology for defining what “net zero carbon” means for buildings in the UK. The Standard provides a set of rules to create robustness and consistency around such claims.

Following the close of the pilot testing, the feedback was analysed, collated and shared in the standard’s December 2025 Pre-Launch Update, as well as being incorporated into the development of Version 1, ensuring the standard will reflect the real-world insights shared ahead of the launch. A further pre-launch update was published in February ready for the March 2026 launch.

New annexes will be published as part of Version 1 on: Delineation, Deeming to Satisfy (formerly known as “Equivalence”) and an optional validity check at Practical Completion. The standard’s section on Verification will also be fully updated to detail the process, and how users will be able to communicate their Net Zero Carbon Aligned status.

Supporting resources also planned for publication include guidance for existing and heritage buildings, guidance for the legal profession on how to incorporate the standard into contracts, and further graphics and videos to support understanding and use of the standard.
