- UK broadband operator G.Network has entered administration after struggling with rising debts and slow customer growth.
- Alvarez & Marsal is managing the process, aiming to keep services running and find a buyer, but the future of the company and its ambitious expansion plans is uncertain.
What happened: Broadband provider’s financial distress leads to administration
London full-fibre broadband provider G.Network has formally entered administration after accumulating around £300 million of debt and attracting relatively few customers compared with its network reach.
The move follows G.Network’s acquisition last week by distressed debt specialist FitzWalter Capital, which quickly applied to appoint administrators a week after taking control. The professional services firm Alvarez & Marsal Europe LLP has been appointed to oversee the process, including seeking potential buyers for the business while keeping operations running.
Founded in 2016, G.Network built a full-fibre-to-the-premises (FTTP) broadband network covering roughly 400,000 homes in London, but is understood to have served only about 25,000 customers at the time of its sale, a modest commercial uptake relative to its infrastructure footprint. The company’s plans once included extending its network far beyond central London, supported by significant investment pledges from shareholders such as the Universities Superannuation Scheme and Cube Infrastructure Managers and secured financing, but those ambitions have stalled.
Administrators have stressed that broadband services will continue to be provided to existing and new customers during the restructuring period, but the appointment marks a dramatic shift for one of the UK’s better-funded alternative network operators.

Why it’s important
G.Network’s entry into administration highlights broader financial strains in the UK’s so-called “altnet” sector — alternative network operators that have been building full-fibre broadband networks to challenge incumbents such as BT’s Openreach and Virgin Media O2. Despite significant investment by private equity and pension funds in recent years, slower-than-expected customer growth combined with high build and financing costs has crimped cash flow for some operators.
Industry analysts have pointed out that many such networks carry high levels of debt, with combined net borrowings across several prominent altnets estimated in the billions, underscoring the risk inherent in the infrastructure build-and-deploy model when commercial traction lags.
The administration also raises questions about how sustainable competition will be in the UK broadband market if smaller challengers cannot convert network reach into profitable customer bases. While administrators are seeking to sell G.Network as a going concern, it is unclear who might step forward with the financial capacity and strategic intent to take on a network with such significant liabilities and mixed commercial results.
For customers, the immediate assurance that services will continue offers some short-term certainty, but the long-term strategic direction of the network — including investment in upgrades or expansion — remains uncertain. The situation also prompts scrutiny of how future broadband infrastructure projects should be financed and regulated, particularly if ambitious build-out plans falter before achieving economies of scale.
