Update, 15 October 2026: Comments closed on Friday 9 October. The Competition and Markets Authority must send its report to the Culture Secretary, Lisa Nandy, by 5pm on Monday 19 October. She will then decide whether the deal goes to a fuller, phase 2 investigation. On 6 October the CMA also served BT with a pre-emptive action order, which limits what BT can do to combine the businesses while the inquiry runs. We will report the outcome.

On 5 October 2026, BT acquired TalkTalk Telecommunications and its wholesale arm, PlatformX, out of administration, at an estimated cost of around £400m. BT says the deal protects 1.5 million retail and 1 million wholesale customers, including vulnerable households and connections used by health and emergency services, and calls it "the only viable option to keep millions of customers connected and supported."

A rescue is better than a collapse. But look at what it leaves. BT already owns BT, EE and Plusnet, as well as Openreach, the network most other providers rent their lines from. TalkTalk has long sold itself on price. Folding it into the largest group in the market removes one of the cheaper alternatives for households watching every pound — the people this campaign exists for.

The UK Government has intervened. The Culture Secretary issued a public interest intervention notice the same day, citing among its grounds the "supply to customers who are or may be vulnerable." The Competition and Markets Authority must report by 19 October. BT says the two companies will operate separately and continue to compete until the review concludes.

The CMA invited comments from any interested party until Friday 9 October. WIRES has sent a submission asking that any approval protects low-cost tariffs, makes sure TalkTalk customers on qualifying benefits are offered a social tariff, and rules out forced price rises for vulnerable households.
