Sustainability record for Leeds’ 11 and 12 Wellington Place
MEPC’s grade A offices are the first in the country to achieve a NABERS UK Five Star Energy Rating following a full year of occupancy, underlining its energy efficiency credentials.
The buildings were already the first outside of London to achieve a ‘Design Reviewed Target Rating of Five Stars’ prior to construction, and have now proved their credentials through operational data.
The offices use a renewable energy tariff and 7,500 sq ft of solar roof panels to run the all-electric buildings, meaning they are Net Zero Carbon ready, saving an estimated 407 tonnes of CO2 each year.
This is alongside smart building technology and sustainable travel options such as EV charging points and cycling facilities.
Several buildings have achieved NABERS UK target ratings, but 11 and 12 Wellington Place are the first to achieve it in practice rather than just theory.
The operational performance of the buildings has been assessed by benchmarking the energy consumption against performance data from across UK offices.
Since completion, the buildings have attracted leading organisations including JLL, Lloyds Banking Group, Arup, EY, GHD, and Hill Dickinson, underscoring strong market demand for high-performing, sustainable workspaces.
Administered by the CIBSE Certification, NABERS UK is rapidly becoming the gold standard for assessing operational efficiency in the UK built environment.
Miles Jones, development director at MEPC, the development and asset manager behind Wellington Place, said: “This achievement reflects the vision, dedication and collaboration of everyone involved, from investors and consultants to property managers, contractors, and occupiers who worked to improve energy efficiency, from initial design through to day-to-day operations.
“It marks a significant milestone not only for Wellington Place but for the NABERS UK certification itself. We’re committed to continuing this momentum with future developments that set new standards for sustainability and performance.”
