The Great Consolidation, from the independent comparison service BroadbandSwitch.uk, forecasts a 68% probability that the UK fibre market resolves to three national platforms plus a niche tail by the mid-2030s
LONDON, ENGLAND, UNITED KINGDOM — Britain built more fibre broadband networks than it can pay for. A new report puts the odds on how that ends.
The Great Consolidation, published today by the independent comparison service BroadbandSwitch.uk, forecasts a 68% probability that the UK fibre market resolves to three national platforms plus a niche tail by the mid-2030s. It gives a 27% chance of a slower, messier shake-out, and just 5% that today’s crowded market survives intact.
The numbers behind the call are blunt. More than one hundred independent networks, known as altnets, raced to lay fibre after 2020. They now pass 19.7 million premises, but only 18% of the homes they reach actually take a service, against roughly 38% at Openreach. The sector carries more than £9bn of debt and lost £1.5bn in 2024 alone, according to Enders Analysis.
For households, the report’s answer comes first: broadband almost never stops working when a provider is bought or fails. The fibre in the ground is a working asset that passes to new owners, and both of this year’s distress cases kept customers connected throughout. The open question is price. Competition helped cut average broadband bills by around 6% in real terms in a recent year, and fewer rivals on the street means less of that pressure.
“While consolidation brings new terms and administrative hurdles, the physical fibre remains secure. Ultimately, this transition means a new name on the bill, not a lost connection.”

Unusually for market analysis, the forecast is designed to be marked. The probabilities were published on 12 June 2026, every figure in the report carries a date and a named source across 75 references, and the resolution criteria will be scored in public in 2028, whichever way events land.
The Great Consolidation is the twenty seventh research report from BroadbandSwitch.uk, following The Last Dial Tone, its June 2026 forecast of the analogue phone switch off.
