NABERS UK has expanded to include Whole Building and Tenancy ratings, alongside the existing NABERS UK Base Building rating to complete the NABERS UK Energy for Offices suite.  Our accompanying NABERS UK training programme also reflects these updates to the scheme.  These updates to the scheme have been completed in April 2023.

Anyone in the process of completing the training will now have access to Whole Building and Tenancy rating modules alongside Base Building.  For anyone who has completed the training, you will have access to the revised training content through your BRE Academy dashboard and the original course now reflects the Whole Building and Tenancy changes to the scheme to support you in your journey as a Licensed NABERS UK Assessor.

NABERS UK is a new scheme for rating the operational energy efficiency of UK offices. NABERS UK will play a vital role in bridging the performance gap between the design and in-use energy performance of offices in the UK and create much-needed transparency for the market.

NABERS UK Energy ratings measure and verify the actual energy use of existing offices, providing a rating from 1-6 stars. This rating will help office owners to accurately target, measure and communicate the energy performance of their buildings. The rating system encourages improvements and therefore office owners can demonstrate improvements in energy consumption, which can be used to demonstrate whether offices are on a net-zero carbon trajectory and provide investors and occupiers with the confidence that the buildings they own and occupy are aligned with their climate change ambitions.

This fully online training course is specifically designed for built environment professionals that have a background in the energy management of office buildings.  The training focuses on the NABERS UK rating process and methodology. Course fees include training and exam administration.

At this time, only training provided by BRE Global is considered acceptable for eligibility for NABERS UK licensing.  Once a Candidate has completed the training and successfully passed the examinations, they will be eligible to apply for a NABERS UK license within one year of successfully passing the exam.  Candidates who do not apply for a license within that time period will need to retake the course to regain their eligibility for licensing.

While there are no formal prerequisites to carry out this training course, we recommend that the ideal candidate will have:

  • formal qualifications, or be skilled in the energy management and operation of offices and energy rating systems;
  • experience in energy efficiency projects in buildings;
  • an ability to read a single line diagram and understand how low voltage electricity is supplied throughout a building to different electrical boards;
  • an ability to identify time scheduling methods, operate a building management system, identify any meters on-site and discern between different mechanical equipment.

We also encourage you to register for the free introductory online NABERS Essentials course, where you can learn about the basics of NABERS ratings, as they are offered in Australia.

This course is for any individual that would like to become a NABERS Energy for Offices Assessor. The course is delivered fully online. You may start and stop the course as many times as you like. You must pass each of the three sections in order to move onto the next.

It contains three modules and three associated exams:
