The Government’s Building Digital UK agency has today published the latest Q4 2025 progress report on their £5bn Project Gigabit broadband rollout scheme. The data reveals that some 1.37 million premises have now received coverage from BDUK’s gigabit programmes since their inception, albeit only 177,840 via Project Gigabit’s GIS contracts (up from 131,090 in Nov 2025).

At present over 89.6% of UK premises can already access a 1000Mbps+ capable broadband network (here) and Ofcom separately forecasts that this could rise to between 91-97% of homes by January 2028 (here). Most of this has been delivered by commercial deployments (predominantly focused on urban and semi-urban areas), but there are some areas in the final 10-20% of premises that are simply too expensive for commercial providers.

Project Gigabit itself was originally established in 2021 to help extend broadband ISP networks capable of delivering download speeds of at least 1000Mbps (1Gbps) to achieve “nationwide” coverage (c.99%) by 2030 2032 (here) – focusing on the commercially unviable areas (usually rural and semi-rural locations). The project has already committed most of its budget up to 2030, but there are still some contracts yet to be awarded and others that have been scaled-back or switched suppliers (here, here, here and here).

The latest update builds on BDUK’s prior report and covers the period between 1st October and 31st December 2025, although it should be noted that the agency tends to publish a separate and more regular monthly update in order to cover the progress of individual contracts under the Project Gigabit scheme (here). Today’s report is thus more of a general overall progress update, without any individual contract specifics.

The latest Q4 2025 BDUK data

Of the premises delivered by BDUK between 1 October 2025 and 31 December 2025: 

• • 75% (41,830) were delivered under Gigabit contracts, or Government Infrastructure Subsidy (GIS) 
  • 18% (10,150) were delivered by vouchers 
  • 7% (4,050) were delivered by Superfast (e.g. the prior SFBB programme) & Hubs (e.g. Local Full Fibre Networks for the public sector)
• 90% (50,200) of the premises delivered between 1 October 2025 and 31 December 2025 were classified as residential premises and 10% (5,400) were classified as commercial premises.  
• The highest delivery between 1 October 2025 and 31 December 2025 was in England (80%, 45,100 premises), followed by Scotland (11%, 6,200 premises), Wales (9%, 4,800 premises), and Northern Ireland (< 50 premises) 
• Yorkshire and the Humber had the highest delivery between 1 October 2025 and 31 December 2025 among English regions (19% of England, 8,700), followed by the East of England (18%, 8,100) and the North West (17%, 7,700). 

The spreadsheet also includes some additional data and a regional breakdown of the figures, some of which we’ve included below. One key thing to note below is that Project Gigabit itself has still only delivered a relatively small amount of gigabit coverage, with the earlier Superfast Broadband Programme (SFBB) continuing to hold the lion’s share (largely because that ran for many years longer and Project Gigabit is much more recent).
