The City of London Corporation has set a new precedent in sustainable development by formally integrating NABERS UK ratings into its Planning for Sustainability Supplementary Planning Document (SPD). This move positions NABERS UK London as a key framework for achieving measurable energy performance in commercial buildings.

Under the updated NABERS UK planning policy, developers are expected to meet ambitious targets:

• New office developments should aim for a NABERS UK 5-star rating
• Major refurbishments should target a 4-star rating

This policy reflects a growing industry shift toward performance-based sustainability standards and supports the City of London’s goal to reach net zero carbon emissions by 2040.

What Is NABERS UK?

NABERS UK is a building performance rating system adapted from Australia’s successful NABERS scheme. Unlike traditional design-stage assessments, NABERS UK focuses on actual energy use, helping to close the gap between predicted and operational performance.

By requiring NABERS UK ratings in planning, theCity of London NABERS UK approach ensures that sustainability commitments translate into real-world outcomes.
