Your neighbour might have gigabit broadband. You might be on copper from the 1990s. Same street, completely different internet.
Ofcom's Connected Nations 2025 report puts full fibre availability at 78% of UK premises. That sounds like progress. But it means 22% of homes and businesses still cannot get it. Around 6 million premises. Stuck on technology the rest of the country is leaving behind.
What full fibre broadband actually means
Most people do not know the difference between "fibre" and full fibre. Broadband providers have not helped. They have been calling FTTC "fibre" for years.
There are three main connection types in the UK.
ADSL is broadband over copper phone lines. It tops out at around 10 Mbps. Distance from the exchange kills speed. If you are rural, 4 or 5 Mbps is realistic. Millions of homes are still on this.
FTTC (fibre to the cabinet) runs fibre from the exchange to a green street cabinet. After that, copper carries the signal to your home. That last stretch limits you to 30 to 80 Mbps. This is still the most common connection type in the UK. Many providers sell it as "superfast fibre". It is not full fibre.
FTTP (fibre to the premises) is genuine full fibre. The cable runs all the way into your home. No copper in the chain. Speeds go from 300 Mbps to 1 Gbps on most packages.
The speed difference in plain numbers
ADSL: around 10 Mbps download. Enough for one person browsing. Not much else.
FTTC: 30 to 80 Mbps. Fine for most households today. Not future-proof.
FTTP: 300 to 1,000 Mbps. Fast enough for an entire household to stream in 4K at once. Upload speeds match downloads, which matters for video calls and cloud backup.
FTTP also holds speed more consistently. FTTC slows during peak hours because copper is shared infrastructure. Full fibre is dedicated all the way to your door.
Who is building full fibre in the UK?
Four main players are laying full fibre across the country.
Openreach is the biggest. BT's network arm has passed over 16 million FTTP premises. They aim to reach 25 million by 2026. Most providers sell across the Openreach network. That means choice of supplier, even where only Openreach has built.
CityFibre is the largest independent builder. They focus on towns and mid-sized cities Openreach treated as lower priority. CityFibre covers around 60 cities and towns. Providers like Vodafone and Zen sell on their network.
Hyperoptic builds in high-density residential areas: large blocks of flats, apartment buildings, student accommodation. If you live in a big urban development, Hyperoptic may already be in your building.
Dozens of smaller regional builders, called altnets, fill the gaps. Some are community-funded. In rural areas, these operators often build where the big names will not go.
For genuinely rural areas, Project Gigabit is the Government's £5 billion programme to subsidise full fibre rollout. It targets areas where commercial providers have no financial reason to build. Project Gigabit is ongoing. Progress has been slower than original targets, but builds are happening.
The postcode lottery is real
Full fibre availability in the UK is not distributed evenly. Ofcom's data shows coverage above 80% in parts of England. In rural Wales and parts of Scotland, it drops below 30%.
Two houses in the same village can get different answers. One is on an upgraded cabinet and can get FTTP. The other is on old copper with no upgrade in sight. This is not a hypothetical. It happens across thousands of UK streets.

Who is still waiting for full fibre?
Rural postcodes are the obvious answer. Low population density means laying fibre costs more per home connected. That makes it commercially unattractive without subsidy. Not every rural community has a confirmed build date yet.
Listed buildings create a separate problem. Drilling through listed structures requires planning permission. Some listed building residents cannot get FTTP even when the street outside is fully upgraded. They must seek individual dispensation.
New-builds are a frustrating case. The UK Government mandated gigabit-ready infrastructure in new developments from 2022. But developers who built before that date, or who cut corners, sometimes skipped it entirely. A house built in 2021 might have no fibre infrastructure. Brand new, but stuck on copper.
Scotland has lower FTTP coverage than England overall. Urban Scotland, particularly Glasgow and Edinburgh, is well covered. But large parts of rural Scotland have no full fibre. No confirmed build date either. Highland and island communities are often last in any rollout queue.
What to do if you cannot get full fibre
If FTTP is not available at your address, you have three realistic options.
4G or 5G home broadband has improved a lot. Providers like Three, EE, and Vodafone offer fixed home broadband over their mobile networks. Speeds vary by signal strength. In good 5G coverage areas, 100 to 300 Mbps is achievable. Installation is simple: a router that picks up the mobile signal. No engineer visit needed.
Fixed wireless access works in some rural areas. A small receiver on your roof picks up a signal from a local tower or transmitter. Speeds are typically 30 to 100 Mbps. Latency is higher than fibre but lower than satellite. Coverage depends entirely on line of sight.
Starlink is the satellite option. It works anywhere with a clear view of the sky. Typical speeds are 100 to 200 Mbps. Latency sits around 20 to 40ms on the residential tier. Monthly cost is higher than most fixed broadband packages. But for remote addresses with no wired options, it has changed what is possible. The hardware cost and monthly subscription are both dropping as the network matures.
None of these alternatives match the reliability or speed ceiling of FTTP. But they are real solutions. If you are on ADSL in a rural area today, 4G home broadband or Starlink will likely be a significant step up.
Check if full fibre has reached your address
The coverage picture changes every month. New streets get upgraded. New providers launch in areas they skipped before. A postcode with no FTTP six months ago might have two providers competing now.
