Nexfibre Publish Q4 2025 UK Full Fibre Broadband Build Update – 2.6M Premises
Network operator nexfibre, which shares some parentage with its UK ISP partners Virgin Media (O2) and giffgaff, has just published their latest quarterly Q4 2025 build update and confirmed that their new 10Gbps capable Fibre-to-the-Premises (FTTP) broadband network now covers 2.6 million UK premises. But future expansion looks set to come from consolidation.
Just to recap. Back in 2022 Telefónica, Liberty Global and InfraVia Capital Partners setup nexfibre as a new £4.5bn joint venture (here), which aimed to deploy an open access (wholesale) full fibre network to reach “up to” 7m UK homes (starting with 5m by 2026) in areas NOT served by Virgin Media’s own network of 16m+ premises. The funding reflects £3.3bn of fully underwritten financing and up to £1.4bn in equity commitments.
However, as existing readers will already know, nexfibre’s roll-out plan suffered a significant blow last year after Telefonica launched a Strategic Review of their global business (here and here). The decision has since resulted in nexfibre scaling back their planned roll-out, which in practical terms means there isn’t currently a solid build plan for going beyond the current level of coverage. But as the recent deal to acquire Netomnia’s network shows, the focus now seems to be on expanding coverage through consolidation (here).

The latest Q4 2025 build update from nexfibre reflects the aforementioned change and confirms that their full fibre network has now reached 2.6 million premises as ready for service (up from 2.44m in Q3). But as is clear from their latest roll-out update and map, there’s currently no significant new fibre build planned for 2026 (this may change once the deal with Netomnia is done and they can plan for future deployments).
Rajiv Datta, CEO of nexfibre, said:
“With our network now extending to c. 2.6 million premises, we’re proud to be among the UK’s leading alternative fibre providers.
As we look ahead, I’m delighted that our shareholders InfraVia, Liberty Global and Telefónica have announced an agreement to acquire Netomnia, with more than 3 million fibre premises and 460,000 customers.
The combination of nexfibre, Netomnia and more than 2 million Virgin Media O2 premises, which will be upgraded by nexfibre, will create a scaled, financially secure challenger to BT Openreach, with a full fibre footprint of around 8 million premises by the end of 2027.
When combined with the growing fibre footprint of Virgin Media O2, our two networks will collectively reach 20 million premises, giving ISPs a highly attractive wholesale alternative, and enabling faster access to fibre for millions of homes and businesses across the UK.
I look forward to working with the Netomnia team over the coming months.”

Zzoomm could be a good target for Nexfibre. Very little overbuild and in a lot of cases butting up to edge of existing VMO2/Nexfibre areas.
Probably not then, they like to go for those that have lots of overbuild
Looking at that map something feels off, I may have misunderstood the article.
However if you look at the South Lanarkshire area on the map above its showing as green but I am not aware of NexFibre being in this area at all. While South Lanarkshire is quite expansive even if I look at my home town and various other areas next to it, I know this is VM areas served by HFC.
Again I could have misinterpreted the article but I haven’t seen anything NexFibre related in these areas whatsoever.
Is it just me or does it get quite murky in terms of what’s built and what’s built near VMs network.
Apologies if I have missed something happy to be correct if I am wrong.
It’s the age-old problem with putting big county-sized blobs of colour to represent coverage in an area where you actually only have a much smaller reach.
“When combined with the growing fibre footprint of Virgin Media O2, our two networks will collectively reach 20 million premises, giving ISPs a highly attractive wholesale alternative, and enabling faster access to fibre for millions of homes and businesses across the UK.”
‘Highly attractive’ if you’re owned by VM02 parents. VM Wholesale is an illusion.
Yep. If nexfibre wanted to be a true wholesale network, they would have done it already. nexfibre is just a way for Virgin to tell Ofcom they’ve built a wholesale network to alleviate competition concerns, while actually just hosting VMO2-owned ISPs.
based on the thinkbroadband article (https://www.thinkbroadband.com/news/what-would-the-next-bold-move-by-nexfibre-look-like-acquiring-cityfibre) Fibrus would be a good focus for takeover as the deployment is still missing from the map in West Cumbria. It was previously down to get Nexfibre but there is now no sign of this. Would be nice to have a symmetrical provider in the county as only Grain and B4rn are the only networks that do this. Fibrus want £240 a month (at last checking) so smacks of we don’t really want to supply this, everything else is Asymmetrical.
They still haven’t integrated any of the former UPP towns into their list
Am I reading it wrong or did Rajiv put 2 and 8 together to make 20?
I think there may be an element of accounting for future build plans too. Netomnia has not stopped its roll-out until the deal is done and their plan currently envisages reaching 5m by the end of 2027, which may be adopted into the nexfibre strategy – albeit perhaps targeting some different areas than previously planned post-merger.
