A Risk Too Far: Why UK Terrestrial TV Shouldn't Switch Off in 2034

Ian Whittaker joins Justin Lebbon to discuss his report "A Risk Too Far", commissioned by Arqiva, which argues the UK's digital terrestrial television switch-off — technically possible in 2034 — should be delayed to at least 2044. The two spar over whether switching TV entirely to IP delivery would erode the medium's premium, and what it means for households that still rely on terrestrial. Why the report now: A consultation is underway; Whittaker argues the debate has focused too narrowly on cost, ignoring national resilience (terrestrial as a "sovereign asset") and household access. The commercial risk: Once a switch-off is announced and all spend runs over IP, Whittaker predicts boards will treat TV, YouTube and TikTok as "one bucket" of video spend, eroding the AVOD/BVOD premium. The numbers: PSB combined ad revenues estimated at ~£3.65bn under a 2044 scenario vs ~£3.1bn if switched off in 2034 — a 16% gap. ITV hit ~12%, Channel 4 potentially ~20%. Justin's counter: Addressable, data-driven, second-by-second BARB-measured IP TV could attract audience-based buyers and command higher CPMs — quality still matters to marketers. The board argument: With marketing treated as a cost under accounting standards, boards under earnings pressure raid the marketing line and favour the cheapest medium. Access divide: ~5.4m primary sets still expected in use in 2034 (per MediaTek), concentrated among older, poorer and rural viewers; gigabit passes ~89% of premises but only ~47% take full fibre. Terrestrial is "egalitarian" — IPTV quality depends on household income and broadband tier. Agencies: Their media profit increasingly comes from proprietary businesses and buying margins, giving them an incentive to push product cost down, not support price inflation. Politics: New PM Andy Burnham's northern working-class seat may shift the calculus; the abolition of DSIT (a stronger backer of the digital move) may help the case for a later switch-off — but the Treasury will weigh in. Key takeaways Whittaker's report 'A Risk Too Far' argues the UK DTT switch-off should be delayed from 2034 to at least 2044. He estimates PSB combined ad revenues of ~£3.65bn (2044 scenario) vs ~£3.1bn (2034 switch-off) — a 16% reduction, hitting Channel 4 (~20%) harder than ITV (~12%). His core thesis: once all spend runs over IP, boards will lump TV in with YouTube and TikTok, eroding the BVOD premium faster than expected. Justin Lebbon counters that addressable, data-driven, BARB-measured IP TV can attract audience-based buyers and justify higher CPMs. Access is a key concern: ~5.4m primary sets still in use by 2034, and only ~47% of premises take full fibre — leaving older, poorer and rural viewers exposed. The decision sits in a consultation period, shaped by national resilience, Treasury views, and shifting political priorities.
