CityFibre Make Business FTTP Broadband Available to 4.5 Million UK Premises

The country’s largest alternative broadband operator, CityFibre, has this morning announced that they’ve “unlocked” their nationwide footprint and made their business Fibre-to-the-Premises (FTTP) services available across 4.5 million premises – offering wholesale business products at data speeds of up to 2.5Gbps (Gigabits per second).

The move comes shortly after CityFibre completed its upgrade from slower GPON to XGS-PON (Symmetric 10Gbps PON) technology, which is how they were recently able to launch a 5.5Gbps speed broadband product at wholesale (here) for residential ISP partners like Sky Broadband to use. But in the meantime, the operator’s business FTTP products have tended to lag behind a bit, although today’s announcement helps to rectify that.

NOTE: CityFibre is owned by Antin Infrastructure Partners, Goldman Sachs, Mubadala Investment Company, Interogo Holding etc. The network is supported by UK ISPs such as Vodafone, TalkTalk, Zen Internet, Sky Broadband and more (local ISP availability does vary). Some 730,000 customers use the network, which as of Oct 2025 covers 4.6 million UK premises (4.3m RFS).

The operator’s new business FTTP services are primarily designed to meet the needs of small businesses, small or home offices (SoHos) and home workers with symmetrical speeds of up to 2.5Gbps, which is useful for data backup, remote collaboration, scalable connectivity, work-ready WiFi for multiple users and more.

CityFibre’s business services also boast of “rapid fix times of less than eight hours and plans to introduce a greater choice of install points, bringing a connection directly to a home office“. The expansion follows CityFibre’s tripling of the availability of its dedicated, enterprise-grade Ethernet services to serve over 260,000 UK businesses, which resulted in over 50% YoY growth in the Ethernet sector for them in 2025.

Andy Nash, Director of Business, Government and Mobile at CityFibre, said:

“Opening up our full FTTP footprint is a game-changer for UK businesses and a great opportunity for our reseller partners. There are hundreds of thousands of small businesses across CityFibre’s network and we’re designing the Multi-Gig, ultra-reliable products they need to innovate and grow.”

Nathan Marke, Chief Strategy Officer at CityFibre partner Giacom, said:

“UK businesses, both large and small, increasingly rely on technology to operate, so reliable, Multi-Gig broadband is key. CityFibre has listened to the market and is making the most of its next generation network to bring greater choice and exceptional products and services to even more businesses across the UK.

Enabling access to the residential as well as business postcodes served by CityFibre’s network, through Giacom’s Cloud Market platform, is great news for our community of 6000 MSPs and expert technology resellers, and means even more SMBs can benefit from high speed, reliable, secure, great value connectivity.”

CityFibre still retains an ambition to extend their network to cover 8 million premises at some point in the future, through a mix of market consolidation and new fibre build. The operator has also recently spoken of their plans for upgrading the network to handle speeds of up to 100Gbps in the not-too-distant future (here).

    I’d love them to do something with their ethernet products that don’t make them feel so neglected. 200Mbps committed for £250 isn’t anything special.

      Historically, CityFibre only allowed its business products to be sold at addresses classified as non-residential. They’ve now updated their terms to allow ISPs to sell business products at any address within the CityFibre footprint. However, ISPs need to agree to a contract variation to take advantage of this change.
