TalkTalk and PXC Leased Lines After the BT Deal
BT now owns TalkTalk's wholesale network business, PXC, subject to regulatory review. What that means for a business on a TalkTalk or PXC-delivered leased line, what does not change, and when to compare the alternatives.

Key Facts
Quick answer
On 5 October 2026 BT bought TalkTalk's consumer business and PXC, the wholesale network arm behind many UK business Ethernet circuits, out of administration. Nothing changes for an existing TalkTalk or PXC-based leased line today: the deal is under government and CMA review, the companies run separately until it concludes, and Ofcom says existing regulatory obligations still apply. The real decision comes at renewal, when a PXC circuit is likely to sit inside the same group as Openreach - which matters most if you rely on it for price competition or as an independent backup path.

When Each Option Wins
Stay on your current TalkTalk or PXC circuit if...
You are mid-contract, the service is good and price was competitive when you signed. The deal does not end your contract, and BT has said it will protect continuity of service. Note your renewal date and diarise a comparison three to six months before it.
Compare the alternatives if...
You are within six months of renewal, you used a PXC-based reseller specifically to get a non-BT price, or your primary and backup lines both ride Openreach. From now on a TalkTalk or PXC circuit and a BT circuit may sit in the same group, so genuine diversity means Virgin's network or an alt-net such as CityFibre.
Renewal is where the money is
Leased line prices are set per address and per route. A renewal that rolls over by default skips the one moment you have leverage: when several carriers can bid for the same building. A multi-carrier postcode check shows every route that reaches you, including Openreach, Virgin and alt-net fibre, with construction charges stated before you sign.

The AMVIA Recommendation
Don't panic-switch and don't auto-renew. If your TalkTalk or PXC-delivered line works, let the contract run while the review concludes. Six months before renewal, get like-for-like quotes across Openreach, Virgin Media Business and the alt-nets for your exact address. If the line is your backup, check what it physically rides: a second Openreach-based circuit was never truly independent of BT's network, and after this deal it is not independent of BT's ownership either.
Get a like-for-like comparisonTalkTalk was never a network owner in the way BT or Virgin Media are. Its business leased lines and the Ethernet it sold to other providers ran through its wholesale division, rebranded PXC (PlatformX Communications), over Openreach and alt-net fibre such as CityFibre. That made PXC one of the main non-BT routes to market for UK business circuits: in September 2022 TalkTalk said its wholesale arm held over 25% of the UK B2B high-speed Ethernet market and more than 3,000 on-net exchanges. Many leased lines sold under other brands were delivered through it.
What happened in 2026
TalkTalk Group spent 2025 and 2026 looking for buyers for its consumer business and PXC. In September 2026 talks with other bidders fell away, and on 5 October 2026 BT bought both TalkTalk Telecommunications and PXC out of administration, run by Alvarez & Marsal, on a debt-free basis. BT put the total cash impact at around £400 million. The government issued a public interest intervention notice, the CMA was asked to report, and Virgin Media publicly objected to the deal. Until the review concludes, BT has said TalkTalk and BT will operate separately and continue to compete. Ofcom said existing regulatory obligations will continue to apply.
What does not change for a business customer
- Your contract: a leased line contract with TalkTalk, PXC or a reseller built on PXC carries on. The government said customers do not need to take any action.
- Your circuit: the fibre to your building, its SLA and its repair arrangements stay as contracted. BT has said it will protect continuity of service, including for critical national infrastructure connections.
- Your renewal rights: if a provider later raises prices beyond what your contract allows or makes significant changes, check your terms; that is the point to take advice and compare.
What does change, and why it matters at renewal
The structural point is ownership. Openreach is part of BT Group. If the deal is cleared, PXC will be too. For years, businesses and resellers used TalkTalk's wholesale Ethernet as a competitive alternative to buying BT direct. That alternative now sits inside the same group, which is exactly the concern analysts raised about wholesale competition. Two consequences follow:
- Price competition at renewal: if your provider's quote rides PXC, it may no longer be the independent bid it used to be. Compare it against Virgin Media Business and CityFibre-based offers for your address.
- Resilience: a primary BT line with a TalkTalk or PXC backup was usually two Openreach circuits anyway. If you want a backup that does not share a network or an owner with your primary, look at a different physical network. Our backup connectivity guide covers how to design that.
How to check what your line actually rides
Your invoice brand rarely tells you the network. Ask your provider three questions: which access network delivers the circuit (Openreach, CityFibre, other), which wholesale platform it is ordered through (PXC or another), and what the notice period and renewal terms are. Then run a multi-carrier postcode check six months before renewal. For the wider market, see our UK leased line providers comparison and the business leased line cost guide.

Frequently Asked Questions
BT agreed on 5 October 2026 to buy TalkTalk's consumer business and PXC, the wholesale and network division that delivered TalkTalk's business Ethernet, out of administration. The deal is subject to a government public interest review with input from the CMA. Until that concludes, BT says the two businesses run separately and continue to compete.
Yes. Buying the business out of administration does not cancel existing contracts, and the government said customers do not need to take any action. Your circuit, SLA and repair terms carry on as contracted. The decision point is your renewal date, not the deal date.
PXC (PlatformX Communications) is the name TalkTalk gave its wholesale and network business, previously known as TalkTalk Wholesale Services and, for business Ethernet, Virtual1. Many leased lines sold under other providers' brands were ordered through it, mostly over Openreach and partly over alt-nets such as CityFibre.
Not mid-contract just because of the deal. Switching early usually means paying out the remaining term and a new install of 30 to 90 working days. Compare properly three to six months before renewal, and act sooner only if service quality changes or you need a backup line on a network BT does not own.
Usually not a fully independent one. Most TalkTalk and PXC circuits ride Openreach, the same access network as BT, and after this deal they may share an owner too. For a backup that survives an Openreach fault, choose a circuit on Virgin Media Business's own network or an alt-net such as CityFibre, and confirm the physical route into your building.
Prices are set per address. Across the market, 100Mbps starts from about £69 a month and 1Gbps from about £129 a month where an alt-net or Virgin is on-net, with Openreach-based circuits and construction charges varying by route. A multi-carrier postcode check gives you the actual figures for your building, typically within 24 hours.
