Six weeks. That was how long it used to take for changes in Ordnance Survey data to reach the teams who needed them. For an Asset Manager monitoring a water network across hundreds of kilometres of ageing pipe, or a Network Planning Engineer modelling new fibre routes through a dense urban area, six weeks is a long time to be working with information that no longer reflects the world it describes.
That cycle is over. The Ordnance Survey National Geographic Database (OS NGD) – launched in 2022 and now updated 20,000 times daily – represents what OS itself has called “the biggest step change in access to OS data in a generation.” And through Idox Geospatial, a strategic OS partner, UK utility companies can access it now, on their terms, without rebuilding their systems to do it.
The question is not whether to migrate. The question is how long you can afford to wait.
What the OS NGD Actually Is (And Why It’s Different)
Previous OS data told you a building existed and gave you its height. The OS NGD tells you its age, its primary construction materials, whether it has a basement, how many addresses it contains, and what it is currently used for. It maps over half a billion geographical features across Great Britain – all structured for analysis rather than simply for reference.
“It’s designed for analytics. It’s designed for ‘ask me a question and I’ll try to answer it’.” – Dean Paulley, Head of Product, Ordnance Survey
For a Risk Analyst modelling asset exposure, or a Utilities Planner assessing how climate change might affect infrastructure in a specific catchment area, this analytical depth is not a nice-to-have. It is what turns a base map into a decision-making tool.
The UK Pressures That Make This Urgent
UK utility companies are navigating a uniquely demanding period. Ofwat’s PR24 regulatory settlement requires water companies to demonstrate evidence-based investment and deliver meaningful leakage reductions – against a backdrop of almost 3,000 million litres wasted daily across 346,000 km of mains water pipes. The target is a 50% reduction from 20178 levels by 2050.
Energy transporters and providers are under tightening HSE requirements – needing precise, current data on which buildings may have exterior cladding, where asbestos might be present in older infrastructure, or where lead piping remains a risk in underground works. These are not abstract compliance questions. They require property-level spatial data that is accurate today, not six weeks ago.
Meanwhile, the UK’s major fibre operators are rolling out connectivity at pace, and every decision – which premises to connect first, which route costs least, where wayleave negotiations are unavoidable – depends on understanding properties in granular detail.
“For utility companies, the OS NGD is an enhancement for their base map. It provides an analytical database that allows them to do more. A lot more.” – Daniel Slater, Commercial Director, Idox Geospatial Division
The Migration Question (And Why It Is Easier Than You Think)
The most common objection is practical. Many utility teams already find six-weekly data updates challenging to process and federate. The idea of moving to daily updates sounds like a system rebuild. It is not.
“We connect utility companies to data that’s built to be consumed in layers, or piece by piece, or however they want to consume it. Their existing applications can connect directly to the data they need, in our managed world. You don’t have to build new systems.” – Daniel Slater, Idox Geospatial
Idox Geospatial’s model is deliberately flexible. Raw data feeds, API access, managed web services – all are available. Update frequency is configured to match your operational reality. You do not need to take the whole dataset; you buy the layers you need, at the scale you need them.
The public sector has already moved. The Office for National Statistics now runs analysis on OS NGD data. Government infrastructure bodies have built systems on it. If your organisation serves a public sector operating on more current information than you are, that gap has a cost.
Net Zero, and What the Data Makes Possible
Every major UK infrastructure operator has a net zero commitment. Anglian Water, Northumbrian Water, and National Highways have signed up to the Construction Leadership Council’s Five Client Carbon Commitments, targeting diesel-free operations by 2027 and net neutrality by 2050. The UK’s major fibre networks have committed to net zero between 2028 and 2050. The energy transition – offshore wind, grid flexibility, distributed generation – is already reshaping the asset landscape.
You can only manage what you can measure. OS NGD buildings data creates the foundation for leak detection and prevention in water networks, energy performance modelling for hard-to-heat homes, real-time asset visibility for all sectors, and the kind of coverage mapping that credible decarbonisation strategies require.
“Decarbonisation and net-zero targets cover so many organisations. There’s going to be a huge focus on modelling the energy performances of buildings to improve the design, reuse of materials, retrofitting, and green energy solutions in future years.” – Jessica Gaskell, Ordnance Survey
That is the foundation on which net zero planning gets done. Without current, granular data, you are modelling a world that no longer exists.

Frequently Asked Questions
What is the Ordnance Survey National Geographic Database (OS NGD)?
The OS NGD is the most comprehensive geographic database for Great Britain, storing all Ordnance Survey spatial data in a single, structured, analytics-ready platform. Launched in 2022, it is updated 20,000 times daily and covers over half a billion geographical features including building age, use, construction materials, land cover, and transport infrastructure.
How does the OS NGD differ from previous Ordnance Survey products like MasterMap?
Previous OS products were updated on a six-weekly cycle and required separate access for different dataset types. The OS NGD consolidates all OS data in one place, updated continuously, and structured for analytics – enabling utility and infrastructure teams to run granular queries against current, accurate data rather than static reference layers.
How can UK utility companies access the OS NGD?
Ordnance Survey provides direct OS NGD access only to Public Sector Geospatial Agreement (PSGA) members and strategic partners. Idox Geospatial is a strategic OS partner and acts as the primary access route for utility companies – delivering data via bulk feed, API, or managed web service at the update frequency and scale each organisation requires.
Do utility companies need to replace their existing systems to use the OS NGD?
No. Idox Geospatial’s approach is additive rather than disruptive. Existing applications connect directly to OS NGD data layers within Idox’s managed environment. There is no requirement to rebuild internal systems, and data scope and update frequency are fully configurable.
How does the OS NGD support net zero targets for UK utilities?
OS NGD data enables water companies to improve predictive leak detection; energy networks to model building energy performance and identify hard-to-heat homes; telecoms operators to plan efficient and cost-effective rollout; and all sectors to build the real-time asset visibility needed for credible carbon reduction planning under Ofwat, Ofgem, and HSE regulatory frameworks.
Which roles benefit most from OS NGD access through Idox Geospatial?
Asset Managers, Asset Data Analysts, Network Planning Engineers, Infrastructure Managers, Utilities Planners, Water Resource Managers, Energy Network Planners, Telecoms Network Planners, and Risk Analysts in utilities and energy all benefit directly from access to current, granular OS NGD data.
