- CityFibre, one of the UK’s largest alternative broadband network operators, plans to cut nearly a third of its workforce as part of strategic streamlining.
- The move reflects a broader shift in the UK full-fibre “altnet” sector from pure build-out to capital discipline and operational efficiency amid rising debt and competitive pressure.
What happened: CityFibre pivots to efficiency as market pressures mount
CityFibre, the UK’s third-largest full-fibre network provider backed by Goldman Sachs, Antin Infrastructure and Mubadala, is significantly restructuring its business, with plans to cut around 450 jobs — roughly one-third of its 1,400-strong workforce on 28 January. This strategic shift was outlined by new CEO Simon Holden, who joined the company in September amid mounting industry headwinds.
CityFibre has long been a central challenger to major incumbents like BT’s Openreach and Virgin Media O2, aiming to extend full-fibre broadband to millions of homes. Yet as debts balloon — around £3.7 billion — and customer take-up fails to accelerate as hoped, the company is reorienting toward simpler operating models and mergers and acquisitions rather than continued aggressive infrastructure build-out.
The workforce reduction follows a £2.3 billion refinancing round in 2025 intended to bolster liquidity and support long-term competitiveness, but also underscores the financial strain on alternative network operators (“altnets”) across the UK. Other smaller altnets have faced distress or collapse, as debt pressures persist in a market of high capital costs and falling broadband prices.

Why it’s important
This development illustrates a pivotal transition in the UK full-fibre market from rapid network expansion to capital efficiency and survival. The early phase of altnet growth — fuelled by cheap financing and ambitious rollout targets — is giving way to a reality where operational efficiency, balance-sheet strength and strategic consolidation are necessary for sustainability. For technology vendors, data centre partners and cloud and edge service providers, this matters because the shape of demand is changing: networks must now offer predictable returns and scalable service economics rather than simply connecting new premises.
The forced pivot underscores broader structural issues in telecom capital deployment: pure infrastructure build-out without robust monetisation strategies is proving unsustainable at scale. As major players like CityFibre prioritise operational discipline and potential acquisitions over standalone growth, smaller operators risk being squeezed out or absorbed, accelerating sector consolidation and altering procurement dynamics for equipment, software and managed services.
