The BT and TalkTalk review, October 2026 19 October is a report, not a ruling. Here is what comes next 5pm, 19 Oct deadline for the CMA's report to the Culture Secretary CMA case page 3 routes clear the deal, accept binding promises, or order a Phase 2 inquiry Enterprise Act 2002 24 weeks for a Phase 2 inquiry, if she orders one, extendable by up to 8 more Enterprise Act 2002, s51 Separate TalkTalk must be run apart from BT until the case is decided CMA order, 6 October On 19 October, the Competition and Markets Authority (CMA) hands its report on BT's purchase of TalkTalk to the Culture Secretary, Lisa Nandy. It's a report, not a ruling: the decision is hers. She can clear the deal, accept binding promises from BT, or send it for an in-depth Phase 2 inquiry that could run well into 2027. Under a new law made on 12 October, promises can't be accepted until Parliament approves it, or 24 weeks pass. Until the case is decided, a CMA order keeps TalkTalk running separately from BT, with its services kept as they are. If you're a TalkTalk customer, there's nothing you need to do. Key facts, checked 15 October 2026 Who this is for: TalkTalk customers who have seen the 19 October headlines, BT, EE and Plusnet customers, people whose broadband comes from smaller providers that use TalkTalk's wholesale network, PXC, families helping older relatives, and anyone comparing deals while the review runs. New to the story? Our 5 October guide covers the takeover itself and your contract rights. Direct answer: By 5pm on Monday 19 October 2026, the CMA must give its report on BT's purchase of TalkTalk to the Culture Secretary, Lisa Nandy. It's a report, not a ruling: the decision is hers. The CMA's case page says the report will cover whether BT's purchase "has resulted or may be expected to result in a substantial lessening of competition" in any UK market. Put simply: has the deal cut competition? It will also advise the Culture Secretary on her decision and summarise what people told the CMA about the public interest. The CMA hasn't published a list of the markets it's looking at. When it looked at BT and EE in 2016, it examined "10 areas of concern", including retail and wholesale broadband. What the CMA's report must cover For scale, BT says TalkTalk brings 1.5 million retail customers and 1 million wholesale customers. Ofcom counted 29.5 million fixed broadband lines in the UK at the end of June 2026, so TalkTalk's retail customers are about 5% of them, by our sum. The CMA's invitation to comment ran from 5 to 9 October and has closed. Direct answer: Because the government used special public interest powers. On 5 October, the Culture Secretary issued an intervention notice, so she decides, weighing competition against keeping phone and broadband services running. Who does what The CMA Looks at competition and reports to the Culture Secretary by 5pm on 19 October. She must accept its findings on competition. The Culture Secretary Lisa Nandy weighs the CMA's findings against the public interest, including keeping phone and broadband lines running, and decides. Parliament Must approve the new telecoms ground added to the law on 12 October, within 28 days, for it to count in full. In her words, "If TalkTalk services fail, there is a genuine risk to life and public services". The government says TalkTalk's networks support "calls to emergency services, ambulance and hospital communications and medical alarms". Ofcom has told BT it is "particularly concerned by the limited visibility of vulnerable customers served indirectly through resellers", such as people whose broadband provider buys its service from PXC. The two public interest grounds Public health emergencies An existing ground in the Act: the need to keep the UK able to deal with public health emergencies. Keeping telecoms running The new ground: avoiding disruption to public services, critical national infrastructure and customers who are or may be vulnerable. The law gives her the final say, but within limits. She must accept the CMA's findings on competition. If the CMA finds a competition problem, the Enterprise Act treats it as against the public interest "unless it is justified by one or more than one public interest consideration which is relevant". So the question becomes whether the public interest outweighs any harm to competition. One catch: until Parliament approves the new telecoms ground, the Act says she must set it aside where it would help justify harm to competition, unless she waits for that approval. Direct answer: Three things: clear the deal, accept legally binding promises from BT instead of a deeper look, or refer it to an in-depth Phase 2 inquiry by an independent CMA panel. Three routes after 19 October 1. Clear the deal What happens She decides not to refer it. The case ends, and so does the CMA's order keeping TalkTalk separate. How long After the report. The law sets no deadline. What it means for you BT can then start bringing TalkTalk in, and says it will give plenty of notice of changes. 2. Accept binding promises What happens BT offers legally binding undertakings instead of a deeper inquiry. How long Not until Parliament approves the new ground, or 24 weeks from 5 October pass. What it means for you BT would be bound by whatever it promised. Nothing has been proposed publicly. 3. Order a Phase 2 inquiry What happens An independent CMA panel investigates in depth, then reports back to her for a final decision. How long Up to 24 weeks, plus up to 8 more, then 30 working days for her decision. What it means for you TalkTalk stays separate from BT for months longer. She can also refer the deal on public interest grounds alone, even if the CMA finds no competition problem. If she clears it, the law says the matter is "finally determined" and the intervention notice ends, and with it the CMA's order keeping TalkTalk separate. No deadline is set for her decision after the report arrives. Direct answer: It adds keeping telecoms services running to the public interest grounds in the Enterprise Act. Until Parliament approves it, the law bars the Culture Secretary from accepting promises from BT instead of a Phase 2 referral, unless 24 weeks have passed. Key dates, so far and still to come The Order was made at 4.07pm on 12 October, laid before Parliament at 5.15pm and came into force on 13 October. It must be approved by each House "within twenty-eight days", with extra time for long breaks. Until then, the Enterprise Act says "No undertaking shall be accepted" while a ground in the notice "has not been finalised and the period of 24 weeks beginning with the giving of that notice has not expired". The Act also lets her wait for Parliament before deciding, for up to those 24 weeks, if she thinks approval is realistic. The new law also lets any enforcement order in a case like this include steps "to maintain in the United Kingdom the continuity of the supply of telecommunications services". Direct answer: Very little that would change your service. A CMA order made on 6 October keeps TalkTalk running separately from BT, with its brand, systems, customer lists and services kept as they are, until the case is decided. The order mainly ties TalkTalk's side. The CMA has agreed that BT can keep running and changing its own services as normal, and that named BT people can help stabilise TalkTalk under strict conditions, including confidentiality. BT has named Clive Selley CBE to lead "the stabilisation and integration planning". Planning is allowed; merging the two businesses isn't, while the order is in place. Direct answer: It depends on the route. Clearance could come soon after 19 October. Promises need Parliament's approval first. A Phase 2 inquiry has 24 weeks, which can be extended, then 30 working days for the final decision. How long each stage can take As an example, if she referred the deal in late October, the panel's report would be due around April 2027, or June 2027 with the full 8-week extension. Her decision would follow within 30 working days. These are our sums from the time limits in the Act, and the timetable can also be extended by agreement. However long it takes, TalkTalk keeps running separately in the meantime. Out of contract? Compare while you wait Nothing about the review stops you choosing your deal. See every deal we can find at your address, with TalkTalk and BT side by side as rivals. Prefer to talk it through? Call 0330 122 1223 Direct answer: BT and EE (2016) and Virgin Media and O2 (2021) were cleared with no conditions. Vodafone and Three (2024) was cleared only with binding commitments, including protected tariffs for new and existing customers. Vodafone and Three is the case that changed things for customers. The CMA found that deal "is likely to have a material upwards impact on retail prices", and said "time limited protections for at least three years" were needed. The final undertakings require named tariffs, including social tariffs, to stay available "to new and existing consumer retail customers" until the Year 3 network milestone. All three cases were decided by the CMA. This one is different, because the Culture Secretary decides. Direct answer: For now, nothing changes: TalkTalk runs separately, and BT says your price and contract stay the same. The outcome mainly decides when, and on what terms, BT can bring TalkTalk into BT. BT says that if changes are ever needed, "we'll explain them clearly, give you plenty of notice". Ofcom's rules still apply too: our 5 October guide explains your right to leave if your terms are changed for the worse. BT has announced no changes for BT, EE or Plusnet customers. If your broadband comes from a smaller provider that runs over PXC, the CMA's order covers PXC as well, so it keeps running separately from BT. Direct answer: Nothing, unless you want to. Keep dealing with TalkTalk as normal, treat any pushy message with care, and if you're out of contract, compare whenever it suits you. Four signs a message about the deal is genuine Comes through TalkTalk BT says it will use "recognised TalkTalk channels" to contact you. Mentions the review Messages BT sends under the CMA's permission must say the review is ongoing and TalkTalk runs separately. Keeps you with TalkTalk They must also say you keep dealing with TalkTalk for your account until the review ends. Never asks for passwords BT says it will never ask for passwords or full banking details by email, text or an unsolicited call. If you have a problem with your TalkTalk service, TalkTalk still handles it. If it isn't sorted, TalkTalk's complaints page points you to CISAS, an independent dispute resolution scheme. Since 8 April 2026, you can take an unresolved complaint to the scheme after 6 weeks, down from 8. Our guides to broadband complaints and telecoms scams have more. If you rely on a telecare alarm, our landline switch-off plan covers the separate January 2027 deadline. Direct answer: The big one: 19 October isn't a decision day. It's when the CMA reports. And BT has already bought TalkTalk; the review decides whether, and on what terms, BT can bring TalkTalk in. Myth or fact? Six things people assume Direct answer: Watch the CMA's case page and government announcements. In the Telegraph case in 2024, handled the same way, the CMA's reports were published on the day they were delivered. We'll update this page as soon as there's news. BT tells TalkTalk customers: "We will update this page when there is meaningful news and send you regular updates." You can follow the official record on the CMA case page. Nobody has said yet whether, or when, this report will be published. Free and independent. Deals listed by price, lowest first. Whoever owns your provider, you choose your deal See what's available on your line today, from BT, TalkTalk and every other provider we can find. Prefer to talk it through? Call 0330 122 1223 In summary Alex's closing thought It's easy to read "19 October" in a headline and expect a verdict that day. What actually arrives is a report, and the decision that follows could take days or months. The reassuring part is that the system is built to protect households while it runs: TalkTalk has to keep going as it is, and BT can't fold it into BT for now. And past cases show that when regulators spot a risk to prices, they can and do insist on protections. We'll update this page the moment there's news.

In a sentence: By 5pm on 19 October 2026 the CMA must report to the Culture Secretary on BT's completed purchase of TalkTalk, and she then decides whether to clear the deal, accept binding promises from BT (barred until Parliament approves the new telecoms continuity ground or 24 weeks pass) or order a Phase 2 inquiry of up to 24 weeks plus 8, while a CMA order keeps TalkTalk running separately from BT. No. 5pm on 19 October is the deadline for the CMA to give its report to the Culture Secretary, Lisa Nandy. She then decides what happens to the deal, and the law sets no date for her decision. The Culture Secretary. She used public interest powers on 5 October, so she decides, taking account of competition and of keeping phone and broadband services running. She must accept the CMA's findings on competition. She can clear the deal, accept legally binding promises from BT instead of a deeper inquiry, or refer it to an in-depth Phase 2 inquiry by an independent CMA panel. Up to 24 weeks, which the CMA can extend by up to 8 weeks, or longer by agreement. The Culture Secretary then has 30 working days to make her final decision. No. A CMA order made on 6 October keeps TalkTalk running separately, with its own brand, systems, customer lists and services, until the case is decided. It's one possible route. But the law says no promises can be accepted while the new telecoms ground awaits Parliament's approval, unless 24 weeks from 5 October have passed. Nothing has been proposed publicly. The Enterprise Act 2002 (Specification of Additional Section 58 Consideration) Order 2026. It adds keeping telecoms services running, including for vulnerable customers, to the public interest grounds. Each House of Parliament must approve it within 28 days. Nobody has said yet. In the Telegraph case in 2024, which was handled the same way, the CMA's reports were published on the day they were delivered. Keep an eye on the CMA's case page. BT and EE (2016) and Virgin Media and O2 (2021) were cleared with no conditions. Vodafone and Three (2024) was cleared only with binding commitments, including protected tariffs. All three were decided by the CMA, not a minister. No. Keep dealing with TalkTalk as normal. BT says there's no change to your price, contract or how you access billing while the review runs. It should come through TalkTalk's usual channels and mention that the review is ongoing. BT says it will never ask for passwords or full banking details. If unsure, go to talktalk.co.uk or call 0345 172 0088. The CMA's invitation to comment ran from 5 to 9 October 2026 and has closed.

What is BT allowed to do with TalkTalk right now?

The "range and quality" of TalkTalk's services must be "maintained and preserved" Your TalkTalk services carry on as they are.

What happened when other big telecoms firms merged?
Merger Cleared Outcome for customers BT and EE 15 January 2016 Cleared after a Phase 2 inquiry, with no conditions. The CMA found no expected loss of competition, including in retail and wholesale broadband. Virgin Media and O2 20 May 2021 Cleared after a Phase 2 inquiry, with no conditions.
