The UK broadband market has entered a phase where the things that made challenger retail ISPs viable - differentiation, ethics, identity - are now structural liabilities.
Infrastructure owners and scaled ecosystems are setting price floors that layered retail ISP models cannot survive.
The models that will endure are the ones that own infrastructure, command genuine brand scale, or are willing to monetise in ways challengers deliberately avoided.

The economics of pure retail ISP and vISP models in the UK broadband market have broken down.
Fibre customer acquisition has become so aggressively price-competitive that once wholesale access and platform layers are paid for, the retail layer itself is barely viable. Service quality, cleaner pricing, sustainability initiatives, improved hardware and consumer-friendly policies expose the impossibility of the underlying economics.
