The United Kingdom National Energy League is part of the World Championship for Energy Savings (WCES), a global initiative developed under the Global Alliance for Buildings and Construction.
It is implemented in partnership with the Department for Energy Security and Net Zero (DESNZ), which leads the UK's energy and climate policy, including the transition to net zero, building decarbonisation, and energy efficiency frameworks.
The league aims to identify and showcase the most energy-efficient buildings across the UK based on real, measured performance data.
Buildings compete at the national level and may qualify for international recognition at major climate events.
The UK has established a strong regulatory and policy framework to improve building energy performance and reduce emissions.
In this context, the WCES provides a complementary, performance-based approach to identify leading buildings, support market transformation, and inform future regulatory developments.
The league is operated in collaboration with leading industry partners, including:
CIBSE is a leading professional body for building services engineering, supporting the development of knowledge, standards, and best practices in energy performance and sustainable buildings.
