- CityFibre reveals new symmetrical 5.5Gb wholesale product, twice as fast as its fastest, currently available service
- New 5.5Gb service is enabled by CityFibre’s 10Gb XGS-PON upgrade, with even faster, multi-gig services to follow in 2026
3 June, 2025, London: CityFibre, the UK’s largest independent full fibre platform, has today revealed its new ‘Multi-Gig’ broadband product, offering its ISP partners symmetrical speeds of 5.5Gb, more than twice as fast as CityFibre’s current market-leading service of 2.5Gb.
The new wholesale product is made possible by a 10Gb XGS-PON technology upgrade, already rolled out across 85% of CityFibre’s network and due for completion later this summer. This will enable ISPs to introduce the next generation of Multi-Gig broadband speeds to millions of UK consumers and businesses and confirms CityFibre’s place as the market-leading wholesale platform.
The 5.5Gb product will be made available over CityFibre’s full nationwide network, with even faster Multi-Gig services due to launch in 2026. Over three times faster than BT Openreach’s fastest available 1.8Gb downstream / 0.12Gb upstream service, and available at a much lower wholesale cost, CityFibre’s 5.5Gb symmetrical product will enable partners to offer a range of Multi-Gig speed tiers to customers, improving margins whilst providing a valuable customer retention tool for the long term.
Greg Mesch, CEO of CityFibre, said: “The UK’s full fibre future is here, thanks to CityFibre’s powerful, 10Gb XGS-PON network. Our ISP partners are already connecting customers with speeds over 2Gb and exceeding expectations when it comes to quality and reliability, but our next generation of full fibre will set a new standard for what’s possible.
“CityFibre started out to challenge the incumbents and bring choice and competition to the UK market. This is another huge step-forward, giving ISPs more power and flexibility than ever before and bringing affordable Multi-Gig speeds and an unrivalled experience to millions of UK consumers.”
