Ordnance Survey (OS), Great Britain’s National Mapping Service, announces annual results for the financial year ended 31 March 2025 with revenues of £194.6m, representing 4.2% annual growth (2023-24: £186.8m). This performance has been driven by growing demand for OS data and services across both public and private sectors, with notable demand coming from the financial services sector.
The financial services sector is increasingly relying on geospatial data, with OS now the critical layer of the UK’s financial risk infrastructure. Its foundational, authoritative datasets, spanning floodplains, building footprints, building material, number of floors, roof types and proximity to critical infrastructure among others, are helping insurers to sharpen underwriting and property risk assessments for better decision making.
OS has also expanded through its expert partner network, which sells into a range of market segments including financial comparison websites, providing insurers with more detailed and accurate property information. In the past year, financial institutions have also increasingly turned to OS, using the power of the Unique Property Reference Number (UPRN) to improve address verification and reduce fraud.
The public sector continues to deepen its use of OS data; this year marked a significant step forward as OS was named as the operator of the National Underground Asset Register (NUAR), a vital digital map of underground pipes and cables that is essential information for utility companies and local authorities in planning and undertaking work. OS also continues to supply data for critical decision making in housing, utilities, and logistics. Building on its commitment to innovation, OS released several new datasets in 2024/25 offering valuable insights on buildings, including data on over 40 million roofs, that can be used to accelerate the roll-out of solar power energy infrastructure.
Over the past financial year, OS reached more customers than ever before reflecting its impact and reach. In the government and commercial sectors, OS’s National Geographic Database, containing 600 million location features and updated 30,000 per day, is a trusted, foundational infrastructure for the UK economy. In the consumer market the OS Maps leisure app continues to help more people explore and enjoy the great outdoors, increasing subscribers by 6%.
Nick Bolton, Chief Executive of Ordnance Survey, commented:
“OS is an organisation with over 230 years of history, and we continue to innovate to meet the evolving needs of the nation. Over the past year, we’ve focused on enhancing and connecting datasets to unlock deeper insights, supporting everything from housing growth to strengthening environmental resilience. This work is helping to build stronger communities and drive economic opportunity across both public and private sectors.
“Despite a challenging economic backdrop, OS has delivered growth, reflecting the increasing demand for trusted location data. Today, our data is estimated to be used 42 times a day by every UK adult, underpinning critical services from emergency response to infrastructure planning and financial risk assessment. We are now in a strong position to deliver even greater geospatial insight and completely fulfil our role as the National Mapping Authority.”
