NABERS UK Version 2.0 will launch on Wednesday 19th of April, completing the NABERS UK Energy for Offices suite.

We are delighted to let you know that NABERS UK Version 2.0 will launch on Wednesday 19th of April. This will extend the NABERS UK scheme to include Whole Building and Tenancy ratings.

These two additional ratings will join the NABERS UK Base Buildings rating, launched in November 2020, and will complete the NABERS UK Energy for Offices suite.

We will shortly be releasing ‘the rules’ documents on our website and invite those interested in registering a project against NABERS UK Version 2.0 or becoming a licensed assessor to keep up to date through the form below.

NABERS UK Version 2.0


BRE have been working very closely with NABERS and BBP on operationalising Whole Building and Tenancy assessment offerings for NABERS UK. Once launched, office tenants will be able to use NABERS UK to assess the energy used by their tenanted space. Typically, this would include lighting and power, special tenancy requirements or local air conditioning.


Additionally, building owners will be able to undertake assessments on their whole building. This allows the sum of the base building and all the tenancy ratings in the building. This rating can also be used by owners where the metering configuration does not facilitate base building rating.



Buildings can be rated based on their central services like heating and cooling systems, lifts and lobby lighting.




Enables energy used by the tenant to be rated, typically for lighting and power, plus special tenancy requirements or local a/c.




Provides assessment of energy used by office tenancies and by Base Building services to lettable and common spaces.


Details of the launch will be going out through our usual communication channels, but if you are keen to keep up to date, we can add you to our registered interest list.
