Leeds Building Society has launched a new partnership with Experian to improve the accuracy of its reported financed emissions within its residential lending portfolio.

The society said the move aligns with the transition to a low-carbon economy and the Government’s net-zero ambition.

By deploying Experian’s datasets, Leeds Building Society has been able to access aggregated and anonymised property level energy data and emission factors for properties in its portfolio.

This has removed its reliance on estimated energy performance certificate (EPC) data which had made the society overestimate its residential mortgage emissions by more than a third (36%).

Head of prudential and enterprise risk at Leeds Building Society, Graeme McRitchie, said: “Improvements in the accuracy of our climate data is key to underpinning our climate transition plan to ensure we are accurately reporting and informing our reduction plans.

“We are delighted with the impact Experian’s Meter Insights has already had on our reporting, and shows how accurate data can have a real, tangible impact on businesses.”

Director of market engagement, business information at Experian UK&I, Scott Harrison, said: “Rich granular data is fundamental for any business wanting to achieve its goals.

“Experian’s first-in-class data expertise means we can support pioneers such as Leeds Building Society, helping them move away from estimated to far more accurate, precise financed emissions data.

“This not only ensures higher quality reporting but also enables lenders to track tangible progress. Ultimately, it will help them comply with upcoming mandatory reporting rules as they work towards the goal of net-zero.”
