Overview: Leeds Building Society enhance measurement of mortgage emissions
How did our Meter Insights product help Leeds Building Society?
Leeds Building Society is the fifth largest building society in the UK, with assets of £31.6 billion. They provide residential mortgages through a network of approved mortgage brokers and directly to members. As a mutual organisation, they are owned by their members and act in their best interests over the long term.
The switch to Meter Insights data has not only improved data quality and reporting accuracy, but also enabled efficient, cost-effective, and GDPR compliant data access. This has provided greater confidence in their reporting and streamlined the production process.
Challenge overview
The UK’s housing stock is one of the oldest and least energy-efficient in Europe. In fact, nearly 90% of the total carbon footprint of financial institutions, such as banks and building societies, comes from the carbon emissions of the properties and projects they finance.
