BT–TalkTalk deal faces public interest review, report by 19 Oct

The Secretary of State for Digital, Culture, Media and Sport issued a public interest intervention notice on 5 October 2026GOV in relation to the completed acquisition by British Telecommunications Limited of TalkTalk Telecommunications Limited and PlatformX Communications LimitedGOV. The notice invokes the existing public interest ground of public health emergency together with a new proposed ground of preventing disruption to public services, critical national infrastructure, and supply to customers who are or may be vulnerableGOVGOV, under sections 42(2), 58(2E) and 58(3) of the Enterprise Act 2002GOV.

The effect is that the Secretary of State, not the CMA alone, will decide whether the transaction operates or may be expected to operate against the public interestGOV and whether it should go to a phase 2 assessmentGOV, taking account of both competition and public interest issues. The CMA must still investigate and reportGOV: its report to the Secretary of State is due by 5pm on 19 October 2026GOV under section 44 of the ActGOV.

That report will cover whether the transaction has created a relevant merger situationGOV and, if so, whether it has resulted or may be expected to result in a substantial lessening of competition in any UK market for goods or servicesGOV. It will also advise on the considerations relevant to a reference under section 22 of the Act so far as they bear on the Secretary of State's decision, and summarise representations received on the public interest considerations specified in the notice.

Third parties can feed into the assessment now. The CMA invites comments on the transaction from any interested party on competition or public interest issuesGOV, with written representations due by 9 October 2026GOV, sent to bt.talktalk@cma.gov.ukGOV. The window runs 5 to 9 October 2026, so interested parties have days rather than weeks to respond.

For merger parties and advisers, the timetable is compressed twice over: representations within the week, and the CMA's report to the Secretary of State by 19 October 2026. Anyone whose interests turn on continuity of TalkTalk or PlatformX services — including arrangements serving vulnerable customers — should consider whether to make representations on the public interest grounds as well as on competition effects.

Legal basis: public interest intervention notice of 5 October 2026 under sections 42(2), 58(2E) and 58(3) of the Enterprise Act 2002, with the CMA's reporting duty under section 44 of that Act; operative dates and contact details in the CMA's BT/TalkTalk merger inquiry case page.
