NABERS UK Licensed Assessors are a professional team of sustainability consultants, trained and licensed to perform NABERS ratings.


Assessors can generate independent revenue through NABERS assessments and can use the NABERS Licensed Assessor logo to promote their services.

What do Assessors do?


Licensed Assessors carry out physical assessments of buildings to collect and then verify the data required to provide a NABERS Energy for Offices rating.

Once the information is collected and the rating is calculated, the Assessor submits it to the NABERS Technical Team who carry out an audit of the information before certifying the building with the final rating. NABERS ratings can only be performed by Licensed Assessors, who collect and verify all the data for a rating according to the NABERS rules or validation protocols.

Look for the NABERS Licensed Assessor logo. Only NABERS Licensed Assessors can use this symbol to promote their services.


Am I eligible?


Anyone is eligible to do Assessor training. An ideal candidate will already have formal qualifications or be skilled in the management and operation of buildings.

If you have experience in energy efficiency in buildings, you may also be suited.
