Three fibres on one street

Walk a mile of inner London, Leeds or Manchester in 2026 and you can still see the history of British broadband stacked on the pavement: a grey copper cabinet, a newer green full-fibre frame, sometimes a third box from an alt-net that arrived while the first two were arguing about ducts. The national story is no longer “will fibre come?” It is “which fibre, on which terms, and is the one in the advert actually the one in your wall?”

A national average is not a service

Ofcom’s Spring 2026 Connected Nations snapshot put full fibre at about 24.9 million homes — roughly four in five — and gigabit-capable broadband near 90%. Thinkbroadband’s mid-year tracking sits in the same band: around 85% of premises can order an FTTP service from someone, and just over 90% can order a gigabit-capable line if you include Virgin Media’s remaining hybrid-fibre coaxial network.

Those figures are useful for politics and almost useless for a household. Availability is an address fact. Openreach, CityFibre, Virgin Media / Nexfibre, Community Fibre, Hyperoptic, YouFibre, Gigaclear and a long tail of regional builders do not share a single map. A postcode can contain a block that is live, a terrace that is “coming 2027”, and a mews the surveyor has not finished.

Coverage is not a vibe. It is a particular socket, on a particular network, ready for a particular order.

Who actually built what

Openreach remains the giant. Independent tracking in early September 2026 put its ready-for-service full-fibre footprint at 23.5 million premises — about seven in ten UK homes and businesses — with the long-stated 25 million target now a matter of months rather than years. CityFibre is the largest wholesale alt-net, a little over four million ready-for-service premises. Netomnia / YouFibre, Nexfibre, Community Fibre and Hyperoptic each pass more than a million. Rural specialists such as Gigaclear sit in the hundreds of thousands, which is everything if you live on their lane and nothing if you do not.

Take-up still lags build. Ofcom counted about 12.4 million live full-fibre connections at the start of 2026. A street can be “covered” for years before most of the houses have moved off copper. That gap is why a comparison that starts from the premises — not from a national league table — is the only honest one.

When three vans can serve one door

Point Topic recorded more than 13 million premises with two or more FTTP networks by the first quarter of 2026. In parts of London, Birmingham and a cluster of smaller cities, three is no longer exotic. Overbuild is good for the person who bothers to compare: it is how an alt-net 900 Mbps lands on a first-year cost that undercuts an incumbent 150 Mbps with a longer promotional teaser.

It is also how people get confused. An advert that says “full fibre in your area” may mean a network you cannot order, a network that stops at the cabinet, or a wholesale product rebadged by three retailers. The only reliable sequence is: postcode, address, then the list of products that can actually be supplied there.

Passed, live, and “coming soon”

Networks love the verb “passed”. It photographs well. It is also three different facts pretending to be one. A premises can be in a build polygon, have a chamber at the kerb, have a blown fibre to the boundary, have an ONT on the wall, or have an active service. Only the last of those is broadband. The others are a project.

“Coming soon” is weaker still. Build dates slip because of wayleaves, blocked ducts, streetworks permits and the weather. If a comparison or a provider page cannot give you an orderable product, treat the date as a diary note, not a promise. Register interest with the builder. Do not terminate a working contract on the strength of a orange sign in the road.

What to do with the map

The quiet revolution is not that fibre exists. It is that, for a growing majority of British addresses, choosing broadband now looks more like choosing a supermarket than waiting for a utility. The work is to keep the choice honest — address first, full cost second, and no borrowed authority from Ofcom or TOTSCo along the way.
