The government has confirmed a £180 million programme for the National Timing Centre, led by the National Physical Laboratory, to deliver a terrestrial timing signal for the UK. Announced on 7 March 2026 to coincide with British Science Week, the initiative is designed to keep mobile networks, online banking and other critical services operating if satellite timing falters.

Telecoms, finance and emergency services largely depend on Global Navigation Satellite Systems for precise time. Those space‑based signals can be disrupted by jamming, spoofing or technical faults, a risk underscored by repeated interference linked to the war in Ukraine. A UK government study estimates a nationwide GNSS loss would cost about £1.42 billion after 24 hours. (gov.uk)
Under NPL’s programme, a resilient time signal will be distributed free over the air, via the internet and by fibre. Two dedicated sites will host high‑stability atomic clocks to anchor the service, providing an assured alternative when satellite timing is degraded or unavailable. (gov.uk)
Funding moves the project from a multiyear R&D phase, which concluded in March 2025, into deployment. Earlier DSIT allocations set out £68 million for the National Timing Centre in 2025/26 and £71 million to start work on a national eLoran system-part of a wider Positioning, Navigation and Timing resilience plan. DSIT has flagged the NTC business case as proceeding through approval. (gov.uk)
Science Minister Lord Vallance described the upgrade as a safety net for national security and the economy. NPL’s chief executive Pete Thompson said assured timing would support industry and future secure applications. The department is led by the Secretary of State for Science, Innovation and Technology, Liz Kendall. (gov.uk)
For operators, the technical significance is direct. 5G base stations require tight synchronisation to avoid interference; replacing a single point of failure in satellite timing with a terrestrial backup reduces systemic risk. NPL already provides trusted network time protocol services at no charge, and the NTC will extend assured synchronisation paths into fibre and radio. (gov.uk)
Procurement activity has been under way since last year. A DSIT pipeline notice for National Timing Centre Delivery Programme Year 1, published on 22 May 2025, set an indicative contract window from 8 July 2025 to 31 March 2026, signalling the shift from design to build.

The programme also includes skills development to expand UK expertise in precision timing, with new routes for graduates, apprentices and, over time, PhD‑level training. In parallel, NPL is working with companies on applications across navigation, communications and radar. (gov.uk)
Taken together with work on eLoran, the National Timing Centre gives the UK multiple, mutually reinforcing timing routes-space‑based and terrestrial-that are harder to disrupt. The policy direction is to diversify PNT sources to protect essential digital infrastructure and the wider economy. (gov.uk)
