14 million UK premises have full fibre available but unused

A new BroadbandSwitch.uk report says about 14 million UK homes and businesses can already order full fibre but have never connected, even as coverage reaches 82% of UK homes. The findings sharpen the focus on switching, rural gaps and the 2027 landline shutdown that could push more households onto broadband decisions.

Why it matters: - The report shows a major gap between broadband buildout and actual use. - Around 14 million UK premises already passed by full fibre have never ordered the service. - That matters because unused availability limits the consumer and economic gains from the national rollout. - The findings also land ahead of the January 2027 analogue phone switch-off, when many households will have to make a broadband decision.

What happened: - BroadbandSwitch.uk released a new independent report, The 82% Country, verified against Ofcom raw data to 24 July 2026. - The report says full fibre now reaches 24.9 million UK homes, or 82% of homes. - The report says gigabit-capable coverage stands at 89%. - Of the premises that can order full fibre, 47% have done so, equal to 12.4 million connections. - The report says 13.9 million premises are passed by full fibre but have never connected. - The report says 6.2 million premises are still waiting for the build to reach them. - The three groups add up to 32.5 million UK premises.

The details: - The report uses Ofcom's July 2026 revision of open data, described as the latest national picture available. - The analysis says 1.2 million homes were added to full fibre coverage in six months. - The report notes that 82% is the homes-only coverage figure, while 81% is the homes-and-businesses base. - Ofcom's own measure shows households that drift out of contract pay £84 to £108 more per year than new customers on the same networks. - Around nine in ten households eligible for a discounted social tariff are not on one, leaving roughly £200 a year unclaimed. - Kingston upon Hull has 99.6% full fibre availability and 78% take-up. - Na h-Eileanan Siar in the Western Isles has 12% availability. - Kensington and Chelsea has the UK's lowest take-up at 19%. - Northern Ireland leads the UK with 95.5% of homes passed and 65% take-up among those with access. - Wales has reached 82.5% of homes passed, level with England. - Scotland sits at 74.9% availability. - The publicly funded R100 programme passed 100,000 connections in June 2026. - Urban areas have 84.4% full fibre availability, compared with 65.6% in rural areas. - About 39,000 premises cannot get a decent connection from any fixed or fixed wireless network. - Most of those premises are in the Scottish islands and rural Wales. - Ofcom estimates that counting affordable satellite services reduces that final figure to around 4,000. - The report is free, runs to 24 pages, and includes a machine-readable data companion.

Between the lines: - The report frames the UK's fibre build as nearly complete, but switching behavior is lagging far behind infrastructure. - The strongest availability figures do not automatically produce the highest take-up, as Kensington and Chelsea shows. - The rural divide remains a real constraint, even as national coverage improves. - The report also highlights that the affordability of satellite alternatives and the need for clear sky access limit how far those services can close the final gap. - The combination of One Touch Switch, the CMA review of nexfibre's proposed acquisition of Substantial Group, and the 2027 landline shutdown could accelerate broadband moves over the next 18 months.

What's next: - The Competition and Markets Authority has until 15 December 2026, unless extended, to review nexfibre's proposed acquisition of Substantial Group. - One Touch Switch passed three million completed switches in June 2026, which could make provider changes easier. - The analogue phone network switches off on 31 January 2027. - BroadbandSwitch.uk says its online report and PDF are available now, along with regional breakdowns on request.

The bottom line: - The UK has largely built the fibre network, but millions of households and businesses still have not used it. The next test is whether policy, pricing and switching rules can turn coverage into adoption.
