The Take-Up Gap: Behavioural Economics of the Broadband Switch
- Jul 28

Full-fibre broadband at £19 per month. Legacy copper-fibre hybrid at £35. One is five times faster. It is also cheaper. Yet across the sector, over 80% of premises passed by an altnet remain on their existing connection. Why?
Start with what you're actually measuring. The industry has no standardised definition of "premises passed." As Light Reading and CityFibre have documented, the commercially meaningful metric is "Ready for Service" — a premises where a customer can order and have a working connection activated within five business days. The gap between reported coverage and actual RFS can be substantial, with real consequences for valuations. This is the first arbitrage opportunity most deal teams miss: overpaying for coverage that isn't yet commercially real.
But even where RFS is genuine, take-up stalls. The standard explanation — "consumers don't know about us" — is wrong. Research commissioned by TalkTalk and executed by Frontier Economics ("Unlocking the Gigabit Dividend") identifies a cluster of behavioural barriers that interact to suppress switching. Three are dominant:
First, inertia. Consumers on legacy FTTC connections that support video calls and streaming perceive no pressing need to change. The performance difference between 100 Mbps and 1,000 Mbps is invisible for most daily use. "Good enough" is the enemy of "better." Second, switching anxiety. Rural users who depend on broadband for remote work and health services experience the migration process as a high-risk event. The fear of a multi-day outage during switchover outweighs the theoretical benefit of faster speeds. Third, brand trust asymmetry. Over 100 new broadband brands entered the market in five years. Consumers cannot evaluate technical performance, so they default to familiarity — even when familiar providers offer slower speeds at higher prices.
The Frontier Economics analysis is valuable for identifying these patterns. Where GreySynth's approach diverges is in what we do with them. Rather than treating behavioural barriers as a sector-level problem requiring policy intervention (Frontier's recommendation), we treat them as a postcode-level diagnostic signal. The acquirer's question becomes: has this specific operator, in these specific communities, demonstrated the ability to overcome these barriers — through local engagement, seamless onboarding, and trust-building — with a measurably rising take-up curve?
