What G.Network does

G.Network is a London-based alternative network (altnet) provider that builds and operates fiber-to-the-premises broadband infrastructure exclusively in Central London. Founded in 2016, the company deployed a fiber optic network spanning approximately 420,000 homes across the capital, targeting residential consumers as its primary customer segment through direct-to-consumer sales. The company differentiated itself environmentally by using biodegradable, soy- or corn-based cable jackets, but this choice became a material operational liability because the plant-based material attracted rodents that caused extensive damage to the network.

The business operates a recurring subscription revenue model, charging residential customers for high-speed fiber broadband service in direct competition with established UK providers such as BT/Openreach, Virgin Media O2, and other altnets including Community Fibre and CityFibre. By January 2026, G.Network had acquired approximately 25,000 subscribers — a penetration rate of only ~6% of homes passed despite years of build-out, signaling substantial underperformance against its commercial potential. Headcount of 501-1,000 employees supporting 25,000 customers reflects a heavily infrastructure-weighted cost base.

The company's financial condition deteriorated sharply: it carried over £300 million in net debt against its modest subscriber base, prompting a lender-triggered sale to distressed debt firm FitzWalter Capital in January 2026. The PE owner subsequently placed G.Network into administration, appointing Alvarez & Marsal Europe LLP to market the business for sale. A potential rescue acquisition by Community Fibre collapsed after the rodent damage was judged too costly to remediate, and the company is currently being shopped to alternative buyers (with CityFibre cited as a candidate and Virgin Media O2 reported to have declined).
