The government has approved a £180 million programme to build a terrestrial timing network, led by the National Physical Laboratory (NPL), with the aim of keeping payment systems, telecoms and other critical services online if satellites are disrupted. Announced on 7 March 2026 to coincide with British Science Week, the National Timing Centre (NTC) moves from R&D to national rollout. (gov.uk)

The commercial case is blunt. The Department for Science, Innovation and Technology (DSIT) estimates a 24‑hour loss of satellite timing could wipe around £1.4 billion from UK output, with recent wartime jamming in Ukraine a reminder that Global Navigation Satellite Systems (GNSS) are vulnerable. For banks and networks, time isn’t a technical nicety-it’s a dependency. (gov.uk)

Rather than depending on a single space‑based feed, the NTC will broadcast a resilient time signal free of charge over the air, the internet and fibre. Two dedicated sites will run high‑precision atomic clocks and distribute signals via fibre, satellites and radio, creating diversity so no single point of failure can take services down. (gov.uk)

For finance teams, this is business continuity in practical terms. Trade timestamping, card authorisations, settlement windows and fraud analytics all rely on traceable, legally defensible time. NPL’s UTC(NPL) standard already underpins such services; the new network extends access and adds domestic redundancy when GNSS is degraded. (npl.co.uk)

Telecoms operators benefit directly. 5G-and future 6G-need tight synchronisation so thousands of devices share spectrum without interference. A terrestrial feed provides a local reference that reduces exposure to satellite jamming and supports denser mobile rollouts and private industrial networks. (gov.uk)

DSIT says the funding will also build skills-creating training paths from apprenticeships to PhDs-so the UK has enough specialists to operate and extend the service. The R&D phase concluded in March 2025; the new investment funds delivery and talent development for the long term. (gov.uk)

NPL frames the approach as combining geographically separated atomic clocks with multiple distribution channels. Recent partnerships and trials, including delivering UTC‑traceable time over Janet with Jisc and demonstrating eLoran radio distribution for grid applications, show how assured time can reach sectors far beyond telecoms.

Ministers are pitching resilience as an economic priority, not an academic one. Science Minister Lord Vallance calls the project a safety net for national security and everyday life, while NPL chief executive Pete Thompson points to benefits for industry and digital infrastructure as the service scales.

What should firms do now? Map where time enters your systems, confirm suppliers can provide UTC(NPL)‑traceable feeds, and schedule failover tests that simulate a GNSS loss. For regulated institutions, incorporate terrestrial timing into 2026–27 resilience plans and vendor contracts.

Procurement watchers should look for milestones on coverage and service levels as the two sites come online. Government tender notices referencing the NTC delivery programme have already appeared, signalling a pipeline across hardware, networks and systems integration for UK suppliers.

The announcement lands during British Science Week, with DSIT highlighting the programme’s role in skills and innovation. The department also notes forthcoming ministerial engagement-another signal that resilient timing is being treated as core infrastructure for the digital economy. (gov.uk)
