The UK’s largest alternative 10Gbps capable Full Fibre (FTTP / XGS-PON) broadband network, CityFibre, has today revealed that their network now covers 4.8 million UK premises (4.6m RFS) and revenues grew to £164m (up 36% from £120m last year). But shareholders have also prepared £900m in a “new equity commitment” to help drive future altnet consolidation.
The details were released as part of a new trading update to 30th September 2026, which also revealed that customer connections had grown to total 1.108 million (up 52%) and consumer revenues had surged by 61% to total £127m (up from £79m). Part of that no doubt reflects the impact of securing Sky Broadband as a major retail ISP partner.
The figures mean that consumer penetration on their wholesale broadband network now exceeds 26%, which continues to trend in the right direction. Adjusted EBITDA (i.e. earnings before interest, taxes, depreciation, and amortization) also quadrupled to £60m, as “customer growth, operating leverage and continued cost discipline drove improved profitability“. This reflects annualised run rates of over £220m p.a. revenue and £100m p.a. EBITDA.
