- Ofcom's Connected Nations report is the authoritative source for full-fibre and gigabit-capable coverage by UK nation and region.
- Coverage is uneven: some nations and urban regions are well ahead of sparsely populated rural areas.
- The gaps are driven largely by the economics of building fibre to scattered premises versus dense ones.
- For the current headline percentages, always read the latest Connected Nations figures rather than older summaries, because coverage is rising quickly.
Full-fibre broadband is being rolled out across the UK at speed, but not evenly. Where you live still strongly determines whether you can get it. Ofcom's Connected Nations report tracks the regional picture, and reading it correctly means understanding both the figures and why the disparities exist.
Where the regional data comes from
Connected Nations is Ofcom's regular report on UK fixed and mobile infrastructure. It breaks full-fibre and gigabit-capable coverage down by the four nations and by region, drawing on operator-reported data. Because coverage is rising rapidly, the precise percentages change with each edition, so the reliable approach is to read the latest report for current figures rather than quoting an older number.
The pattern of the disparities
The broad pattern is consistent even as the numbers move: densely populated urban areas tend to have higher full-fibre coverage, while sparsely populated rural areas lag. Among the nations there are meaningful differences too, shaped by population density, geography and the pace of both commercial and publicly supported rollout. Northern Ireland, for instance, has benefited from earlier targeted investment, while remote parts of Scotland and Wales face the hardest economics.
Why the gaps exist
The core reason is cost per premises. Running fibre to a dense urban street connects many homes per mile of build; running it to scattered rural premises connects few. Commercial operators naturally build where returns are strongest first, which concentrates early coverage in towns and cities. Government programmes such as Project Gigabit exist precisely to fund the harder-to-reach premises that the market would reach last or not at all.
Reading the regional picture
| Factor | Effect on regional coverage |
|---|---|
| Population density | Denser areas covered earlier and more fully |
| Geography and terrain | Remote, rugged areas are slower and costlier |
| Commercial rollout | Concentrates on higher-return areas first |
| Public funding | Targets premises the market reaches last |
How to use the data for your area
Read the latest Connected Nations report for your nation and region to understand the trend, then run an address-level check for what you can actually order. The regional figure tells you the direction of travel; only the address check tells you what is at your door today.
Frequently asked questions
Which part of the UK has the most full fibre broadband?
This varies by edition of Ofcom's Connected Nations report, and Northern Ireland has historically been comparatively well covered due to earlier targeted investment. Read the latest report for current rankings, as coverage is rising quickly across all nations.
Why is full fibre coverage lower in some regions?
Mainly because of the cost of building fibre to scattered premises. Dense urban areas connect many homes per mile of build and are covered first; remote rural areas connect few homes per mile and are slower and costlier, so they lag.
What percentage of UK premises have full fibre?
The figure rises with each Connected Nations report, so quoting an older number is misleading. Check the latest Ofcom Connected Nations report for the current national and regional percentages.
How does Northern Ireland broadband differ?
Northern Ireland has historically had comparatively strong full-fibre coverage, helped by earlier targeted public investment. The latest Connected Nations report gives the current position relative to the other nations.
What is Wales doing to improve broadband coverage?
Coverage in Wales is supported by a mix of commercial rollout and publicly funded programmes targeting harder-to-reach premises, alongside the UK-wide Project Gigabit. Read the latest Connected Nations data and Welsh Government programme updates for current detail.
