- Full-fibre coverage (fibre to the premises) has grown rapidly through both Openreach and alternative network builders.
- The government's wider ambition is nationwide gigabit-capable coverage, supported by the publicly funded Project Gigabit programme.
- Gigabit-capable coverage includes both full fibre and some upgraded cable networks, so it is a broader measure than full fibre alone.
- As of Ofcom's Connected Nations Spring 2026 update (data to January 2026), full fibre was available to about 82% of UK homes (around 24.9 million premises), with about 89% gigabit-capable; both figures continue to rise.
Full-fibre broadband has gone from a minority technology to one that passes the majority of UK homes in a remarkably short time. Understanding the 2026 state of play means separating two related measures, full fibre and gigabit-capable coverage, and reading the latest figures rather than relying on a number that is already out of date.
Full fibre versus gigabit-capable
Full fibre, or fibre to the premises, runs fibre all the way to your home and is the most future-proof technology. Gigabit-capable is a broader category that includes full fibre plus some upgraded cable networks able to deliver gigabit speeds. Government targets are usually framed around gigabit-capable coverage, so the gigabit figure is higher than the full-fibre figure. Keeping the two distinct avoids confusion when comparing headlines.
Who is building it
Two forces drive the rollout. Openreach, the largest network, is building full fibre at national scale and reselling access to many providers. Alongside it, a wave of alternative network operators, the altnets, are building their own fibre, often in areas they judge underserved. Government funding through Project Gigabit targets the premises that neither would reach commercially. Together these have driven coverage up quickly.
What remains to be done
The remaining work is the hardest and most expensive: scattered rural premises, awkward installations, and properties where wayleaves or access disputes slow progress. This is the "final" portion that public funding is designed to address, and it is why nationwide coverage takes longer than the rapid early gains might suggest. Coverage rising past the majority of premises does not mean the last tranche is easy.
Reading the current position
| Measure | What it counts | Where to read it |
|---|---|---|
| Full-fibre coverage | Premises passed by fibre to the premises | Connected Nations |
| Gigabit-capable coverage | Full fibre plus upgraded cable | Connected Nations |
| Government target | Nationwide gigabit ambition | Project Gigabit |
| Remaining premises | Hard-to-reach, publicly funded | Project Gigabit |
What it means for you
The trend is strongly positive, but national coverage figures do not tell you about your specific address. Read the latest Connected Nations report for the current percentages and the direction of travel, then run an address-level check to see whether full fibre has actually reached your home.
Frequently asked questions
What percentage of UK homes have full fibre broadband?
As of Ofcom's Connected Nations Spring 2026 update (data to January 2026), full fibre was available to about 82% of UK homes, around 24.9 million premises, with about 89% gigabit-capable. The figure keeps rising, so check the latest report for the current number.
Did the UK hit its gigabit coverage target?
Government targets are framed around gigabit-capable coverage and have been supported by Project Gigabit. Progress has been substantial, but for the precise position against the target, read the latest Connected Nations data and government updates rather than an older claim.
Who is building full fibre in the UK?
Openreach is building at national scale and reselling access to many providers, while alternative network operators, the altnets, build their own fibre, often in areas they see as underserved. Project Gigabit funds the hardest-to-reach premises.
How fast is full fibre coverage growing?
It has grown rapidly, moving from a minority of premises to the majority in a short period, driven by Openreach and altnet building plus public funding. The latest Connected Nations report shows the current pace.
When will full fibre be available everywhere?
The remaining premises are the hardest and most expensive, mainly scattered rural properties, so full nationwide availability takes longer than the early gains suggest. Public funding through Project Gigabit is aimed at closing that final gap.
