National vehicle data backbone

The secure data network for UK road-usage charging.

VDCN – the Vehicle Data Communications Network – is a proposed national infrastructure platform that securely connects vehicles, public bodies and mobility services. Our purpose is to provide trusted vehicle telemetry for fair, usage-based road charging and smarter transport policy.

Secure by design Neutral & regulated API-first architecture
Why VDCN

A single, trusted source of truth for vehicle data.

Today, vehicle data is fragmented across manufacturers, telematics providers and apps. Governments and regulators struggle to design fair, future-proof road-usage charging because they cannot rely on a single, secure data source that covers all vehicles, all roads and all operators.

National infrastructure

VDCN is conceived as a national communications network for vehicle telemetry, similar in concept to the data backbone used for smart meters, but focused on road transport.

Standardised access

OEMs and commercial data aggregators connect once to VDCN and meet their obligations to supply verified telemetry for taxation and policy – without bespoke integrations everywhere.

Public-interest first

VDCN is designed to be neutral and regulated, serving public bodies, not private data capture. Charges, duties and obligations are transparent and subject to oversight.

What VDCN does

Core services of the Vehicle Data Communications Network.

1 · Telemetry

Collects trusted vehicle data

Securely ingests mileage, odometer and trip summaries from vehicles via manufacturer and data aggregator APIs, applying validation and integrity checks.

2 · Charging

Enables road-usage charging

Applies tariffs set by central and local government to generate usage-based charges that align more closely with actual road use.

3 · Billing

Generates billing records

Produces tamper-resistant billing records linked to registered keepers and exports them securely to DVLA and other authorised systems.

4 · Ecosystem

Supports wider mobility innovation

With appropriate governance, the network can support insurers, fleets and cities in building safer, smarter mobility services using trusted vehicle data.

Stakeholders

Built for government, industry and drivers.

VDCN provides different value for each part of the ecosystem, while keeping a single, consistent source of truth for vehicle usage and charges.

Government & regulators

Department for Transport, HM Treasury, DVLA, devolved administrations and local authorities can design and administer road-usage charging using accurate, trusted data.

OEMs & data providers

Vehicle manufacturers and commercial data aggregators connect once to VDCN, meeting their obligations securely via common standards and governance.

Drivers & fleets

Keepers and fleet managers use the Keeper Portal to see usage, understand charges, manage vehicles and raise disputes – with clear evidence for every record.

Principles

Design principles behind VDCN.

  • Public-interest first – serving public bodies and citizens, not exploiting driver data.
  • Secure by design – modern encryption, strong identity, full audit trails.
  • Neutral & regulated – operated under licence with transparent price control.
  • Technology-agnostic – works with any compliant vehicle, gateway or API.
  • Future-ready – supports EVs, HGVs, connected vehicles and emerging mobility models.

VDCN is intended to be infrastructure that the country can depend on for decades: stable, predictable and governed. While specific tariffs and policies may change, the need for a secure, trusted vehicle data backbone will only grow as transport electrifies and digitises.

Next steps

Get involved in shaping VDCN.

VDCN is designed to support national conversations on how the UK should modernise road taxation and mobility. We welcome engagement from policy makers, regulators, OEMs, data providers and other stakeholders.
