11/12 Wellington Place in Leeds has reached a significant sustainability milestone, becoming the first new buildings in the UK to achieve a certified NABERS UK Five Star Energy Rating, completing the Design for Performance (DfP) process.

11/12 Wellington Place has set a new benchmark for energy-efficient workplace design in the UK after achieving a certified NABERS UK Five Star Energy in Use rating. This achievement marks the successful completion of the Design for Performance journey and demonstrates what can be delivered through a truly collaborative, performance-led approach to building operation.

The milestone was made possible through the combined efforts of developer MEPC Limited, alongside project partners CBRE, Arup, Linear Control Systems Ltd, and NG Bailey’s Facilities Services team. Together, the team has delivered a workplace that not only meets its design ambitions but performs to the highest standard in real-world operation.

At NG Bailey, our data-driven approach to energy management is central to supporting high-performing buildings. By combining on-site engineering expertise with real-time insight from our Facilities Services Advisory team, we enable informed decision-making and continuous optimisation.

For 11/12 Wellington Place, this included deploying a robust energy management platform, establishing virtual meters aligned to NABERS Design for Performance calculations, and undertaking regular weekly and monthly performance reviews. Transparent reporting and proactive optimisation have been key to avoiding performance drift and maintaining operational excellence from day one.

This landmark achievement demonstrates how clear performance targets, strong collaboration and ongoing operational focus can deliver measurable benefits, setting a new standard for sustainable commercial buildings across the UK.
