Verification is coming in Q2 2026
The UK Net Zero Carbon Buildings Standard establishes the requirement for independent, third party verification. The Standard's verification process will provide confidence in buildings’ exemplary performance when they secure Net Zero Carbon Aligned status. The verification framework and methodology are currently being developed in partnership with Bureau Veritas, and will be launched in Q2 of 2026.
Published alongside Version 1, our Verification Primer explains the latest developments on how the verification framework and methodology are expected to operate. It includes explanations of the process, evidence requirements, and pricing. For those considering verifying a building, we recommend both reading the Primer, and familiarising yourself with the Standard.
The Verification Framework
Third party verification is a mandatory part of the process to becoming a Net Zero Carbon Aligned building, as defined within the UK Net Zero Carbon Buildings Standard. The Standard sets out the requirements for verification, and we are working with our partners Bureau Veritas to develop a framework for how the process will be operated and implemented.
The organisation chart on the left shows the framework of organisations / entities that will play a part in the verification of buildings to meet the Standard. More detail on each role is provided in our Verification Primer, alongside further details about how verification will work.
Appointing a Verification Administrator
We are currently in the final stages of appointing Bureau Veritas as the Standard’s Verification Administrator (VA) . Following the launch of Verification, the VA will run and maintain the Standard’s verification process, including developing a verifier training and accreditation scheme that will open up verification services to the wider industry.
Bureau Veritas will carry out the initial verifications “in-house”, up until the training scheme is available. As part of this work, we have defined the competencies a verifier will need, including around whole life carbon assessment. These competencies are available within Section 6.3 of the Standard.
Registration Coming Soon
The first step to securing verification will be to register a building. The Standard's registration portal is being finalised, and will "go live" within the weeks following the publication of Version 1.
Registration confirms the intent to verify a building. Registered buildings will be added to a UK NZCBS Register of Buildings, which will be visible on our website.
Those registering will need to:
-
Provide key information about the claimant and the building.
-
Sign up to terms and conditions.
-
Pay a registration payment.
