Ofcom Has Blocked an Openreach Broadband Discount: What It Means for Your Bill, Your Provider and Your Street

Who this is for: anyone who saw the headline and wondered whether their broadband is about to get cheaper or dearer, anyone in a Virgin Media area who has been thinking about switching, and anyone on a small fibre network who wants to know whether Ofcom just helped or hurt them. Wholesale pricing is the part of the broadband market nobody explains to customers, yet it sets the floor under every bill. This guide sets out what was decided, why, what it means at your address and what to do about it.

What did Ofcom decide on 28 September 2026?

Direct answer: Ofcom assessed six Openreach offers notified in June and July. It blocked one, the Incremental New to Openreach Customer Offer, and let the other five go ahead. It is the first time Ofcom has ordered Openreach to withdraw a commercial offer.

Openreach must give Ofcom and the industry 120 days' notice of any offer whose price depends on volumes, because Ofcom found in March 2026 that Openreach still has significant market power in the wholesale broadband market. The regulator's job is then to decide whether the offer would harm the development of competition between networks. Ofcom said on 28 September that it considered the cumulative effect of all six offers, not each in isolation.

Openreach's response, through its managing director for commercial, James Lowther, was that it had put the offer forward in good faith to help its customers compete and deliver better value, that it still believes the offer would have benefited customers and competition, and that it will review the decision carefully. It confirmed it will launch the other offers, including the one in the Virgin Media footprint. In July, when Ofcom first proposed the block, Openreach had said it did not believe regulation should protect poor business models; the industry body INCA called the proposal an important and timely intervention.

What exactly was the blocked offer?

Direct answer: a targeted discount on customers who were not already on Openreach. Providers that beat a quarterly baseline of new to Openreach orders would have paid £9.50 a month less on the extra lines for 18, 24 or 30 months depending on how far past the baseline they got, and £35 less per connection. Smaller providers would have received it on every such line.

"New to Openreach" has a precise meaning: a premises with no Openreach service of any kind in the previous 90 days. In practice that is three groups of people: Virgin Media cable customers, customers of alternative networks, and homes that have never had broadband from any Openreach provider. New build sites were excluded. The offer was national, for six months from 1 October 2026 with an option to run for 12.

The chart shows why Ofcom took it seriously. Openreach's Equinox price for a 160Mb line is £17.94 a month before VAT. Take £9.50 off and the provider pays £8.44 for the rebate period. Over the full 30 months that is £285, plus the £35 connection rebate: up to £320 a line, on the customers that the smaller networks most need to win. Ofcom's own email put it plainly: a discount of up to £9.50 per customer for up to 30 months that other reasonably efficient operators might not be able to match while also recovering their costs.

Why does a wholesale discount matter to my bill?

Direct answer: because for most big brand broadband, the Openreach charge is the biggest single cost inside your monthly price. Providers such as BT, EE, Sky, TalkTalk, Vodafone, Plusnet and NOW rent the line from Openreach and add their own network, support, router and margin on top.

Nobody publishes the exact split, so the illustration above uses two public numbers: TalkTalk's Full Fibre 150 at £25 a month and Openreach's 160Mb rental of £17.94. Strip out VAT and the Openreach charge is about 86% of what is left. The provider's real position is better than that because Openreach shares revenue above a threshold on faster tiers, and worse because of backhaul and connection costs, but the shape is right. Consumer broadband is a thin margin business, which is why a £9.50 wholesale rebate was big enough to change what providers could offer, and why Openreach based providers write £3.50 to £4 annual rises into their contracts. Our UK Broadband Price Index tracks what people actually pay, and our guide to which providers use Openreach explains the plumbing.

Why did Ofcom block it?

Direct answer: Ofcom's rule, set in March 2026, is that Openreach's full fibre prices must leave enough margin for a reasonably efficient rival network to compete. Ofcom modelled that rival's costs at £13.73 to £21.45 a month per line and found the offer would have pushed Openreach's effective price into the bottom half of that range, and for the deepest rebates below it.

The reasoning rests on a fact about the market. Full fibre now reaches 82% of UK homes and 75% of premises can choose between at least two networks, but around half of the homes able to get full fibre have not signed up. Ofcom's strategy since 2016 has been to get rival networks built and then let them win customers, on the theory that lasting competition between networks is what keeps prices down and service improving for the long term. It says that for altnets, take-up is the whole game: it takes time to build a customer base and reach the scale at which they can hold their own.

That is the imbalance the blocked offer would have widened. Openreach's own full fibre take-up is 40%. Altnets average 18%. A discount aimed precisely at customers who are not yet on Openreach, at a time when altnets are already pricing low to grow, would in Ofcom's judgement have forced them to match at prices below what an efficient operator can sustain. Ofcom was explicit that this is not about guaranteeing any particular altnet's survival, and that Openreach must be allowed to compete on price. Its objection was to a targeted cut, from a company with market power, for the specific customers its rivals depend on.

Two things worth knowing from the responses. Sky, BT and Openreach argued that providers would not have passed the full discount on to any individual customer, because they could not know at the point of sale which new customers would count above the baseline; Ofcom accepted that the retail effect was uncertain. And Openreach argued that most of the customers it would have won were Virgin Media cable users rather than altnet customers, which is part of why Ofcom let the smaller, Virgin Media areas offer through.

What changes for you on 1 October 2026?

Direct answer: on price, nothing. Nothing in today's retail prices depended on the blocked offer, so no bill goes up or down because of this decision. What changes is behind the scenes, and mostly in Virgin Media areas.

• Virgin Media areas. Openreach's £50 connection rebate starts for extra new to Openreach lines in the legacy cable footprint and the Project Lightning areas, around 16 million premises. Openreach's connection charge in those areas is £32.07, so the rebate more than covers it. If it reaches customers at all, expect it as free setup or switching credits from Openreach based providers for people leaving cable, not as a lower monthly price. No provider had announced a deal tied to it by 28 September. Our BT versus Virgin Media and Sky versus Virgin Media comparisons show what the switch looks like today.
• Faster tiers everywhere. Since 1 July, Openreach has capped a provider's average rental on new and upgraded lines at £19.32 and removed the £90 fee for the 2.5G box needed for 1.8Gbps. That makes gigabit and above cheaper for providers to sell; Sky launched a 1.6Gbps package on Openreach on 25 September, from £38 a month. Whether that flows into cheaper gigabit deals is a commercial choice for each provider.
• New build and newly built areas. From 1 December, Equinox pricing extends to Openreach full fibre made ready for service up to 31 March 2027, so a street that gets fibre next spring will be priced to providers on the same basis as everywhere else.
• Business lines. The Ethernet offer for leased lines also starts on 1 October and does not affect home broadband.

Which network is your provider on, and does it matter?

Direct answer: it matters more than the brand. The same provider can sell over Openreach in one town and CityFibre in the next, and the network sets both what you can get and what your provider pays for it.

Some brands cross the lines. Vodafone, TalkTalk, Sky and Zen sell over CityFibre as well as Openreach in the areas CityFibre has built, and Sky's fastest tiers are only available where it uses CityFibre. Virgin Media sells only its own network, and brands such as Community Fibre, Hyperoptic, YouFibre, Gigaclear and Fibrus each sell only on theirs. Our Openreach versus altnet explainer and Openreach versus CityFibre comparison cover the practical differences; the only reliable way to know what reaches your door is to check full fibre availability at your address.

The table is a snapshot, read from each provider's own site on 28 September 2026 without a postcode, and several providers say prices vary by location. The pattern is consistent, though: the cheapest gigabit deals on own networks are £9 to £13 a month below the Openreach based big brands, and the big brands add £3.50 to £4 a year. That gap is what Ofcom is protecting. If the blocked offer had gone ahead, the big brands would have had room to close it for exactly the customers the altnets are trying to win.

Would your broadband have been cheaper if Ofcom had allowed it?

Direct answer: for a few people, for a while, possibly. For most people, no. The discount only applied to customers new to Openreach and only above each provider's baseline, and the providers themselves told Ofcom they would not have passed the full amount on to any individual line.

The honest picture has three parts. First, if you are already with an Openreach based provider, the offer did nothing for you; it was about winning customers from other networks. Second, if you are on Virgin Media or an altnet and were thinking of moving to BT, Sky or TalkTalk, you might have seen a sharper welcome deal this winter; you may still see a smaller one in Virgin Media areas thanks to the £50 rebate. Third, the trade Ofcom made is between that possible short term deal and the survival of the networks whose presence is the reason prices have fallen at all: Ofcom's own figures show real terms gigabit prices falling from over £60 a month in 2021 to £35 to £45 in 2025, and prices falling fastest at the speeds where altnets compete hardest. Whether you think the trade is right depends on how much weight you give to next year's choice against this year's deal.

What happens next?

Direct answer: three dates. Late November for any appeal, 15 December for the CMA's decision on the nexfibre and Netomnia merger, and 2027 for any revised Openreach offer, which would need 120 days' notice.

Openreach can appeal an Ofcom direction to the Competition Appeal Tribunal, normally within two months of publication. CityFibre tried the same route in the other direction in 2022, against Ofcom's approval of the first Equinox offer, and lost; the Tribunal encouraged Ofcom to keep a careful eye on the market. Openreach has not said it will appeal. It has said it will keep engaging with Ofcom, and Ofcom said in March that as competition develops there may be future scenarios in which it can relax its position on Openreach offers. Enders Analysis, writing for ISPreview on 21 September, expects Openreach could try again in 2027 and argues restrictions like this will look harder to justify as altnets grow; that is an analyst forecast, not Ofcom's view.

The other moving part is who the altnets are. The CMA is due to decide by 15 December whether nexfibre can buy Netomnia, YouFibre and brsk, a deal that would create a network of around 8 million premises; our guide to what that decision means for YouFibre and brsk customers and our Great Consolidation report follow it. Ofcom's decision today makes life a little easier for those networks. It does not make them safe, and our guide to what happens to your contract if an altnet goes bust is worth a read if you are on one.

What should I do now?

Direct answer: do not wait for a discount that is not coming. Check which networks reach your address, check your contract end date, and compare the total cost over the contract rather than the headline price.

Frequently asked questions

What did Ofcom decide on 28 September 2026?

Ofcom directed Openreach to withdraw one wholesale offer, the Incremental New to Openreach Customer Offer, because the discounted prices were not fair and reasonable under the rules Ofcom set in its Telecoms Access Review 2026 to 31. It decided not to intervene in Openreach's other notified offers: a £50 connection rebate in Virgin Media areas, the Frontbook ARPU Share and Box Swap offers that started on 1 July 2026, an Ethernet offer for business lines, and an extension of the Equinox pricing area to premises built up to 31 March 2027. It is the first time Ofcom has blocked an Openreach commercial offer.

What was the Incremental New to Openreach offer?

A discount for broadband providers on customers who were new to the Openreach network, meaning no Openreach service at the address in the previous 90 days. Providers that beat a baseline of new to Openreach orders would have received a £35 connection rebate and £9.50 a month off the rental for 18, 24 or 30 months on the extra lines. Smaller providers with fewer than 1,000 orders in April 2026 would have received it on every new to Openreach line. It was due to start on 1 October 2026 for six months, extendable to 12.

Will my broadband bill go up or down because of this?

Neither, directly. Nothing in today's retail prices depended on the blocked offer, so existing customers see no change on 1 October 2026. What has gone is the chance that Openreach based providers such as BT, EE, Sky, TalkTalk, Vodafone, Plusnet and NOW could have used a wholesale discount worth up to £320 a line to fund sharper deals for people switching from Virgin Media or an alternative network. Ofcom's own view was that a large part of that discount might never have reached customers anyway.

Why did Ofcom block a discount? Surely cheaper is better?

Ofcom's test is whether a reasonably efficient rival network, renting Openreach's ducts and poles, could match the price and still cover its costs. It concluded that the discounted prices sat in the bottom half of its cost range, and for the largest rebates below it, so rivals could not. Ofcom's reasoning is that around half of homes with access to full fibre have not yet signed up, and that if Openreach can undercut rivals for exactly those customers, the smaller networks never reach the scale that keeps prices down for everyone in the long run.

Which broadband providers use Openreach?

BT, EE, Plusnet, Sky, NOW, TalkTalk, Vodafone and Zen all sell services over Openreach, and BT Group says more than 700 providers buy from it in total. Virgin Media uses its own cable and fibre network, and providers such as Community Fibre, Hyperoptic, YouFibre, Gigaclear and Fibrus run their own networks. Some brands sell on more than one network: Vodafone, TalkTalk, Sky and Zen also sell over CityFibre in some areas, so the only reliable way to know is a postcode check.

I am in a Virgin Media area. What changes on 1 October 2026?

Openreach's Geographic Incremental New to Openreach offer starts, giving providers a £50 connection rebate on extra new to Openreach lines in the areas Openreach defines as Virgin Media's legacy cable footprint and its Project Lightning expansion, around 16 million premises. It runs for an initial six months. The £50 is more than Openreach's £32.07 connection charge in those areas, so providers may use it to fund free setup or switching credits for people leaving Virgin Media. No provider had announced a deal tied to it by 28 September 2026.

What is Equinox?

Equinox is Openreach's long term full fibre pricing contract for broadband providers. It began on 1 October 2021 and runs to 30 September 2031. Providers get lower rental prices, for example £17.94 a month for the 160Mb tier from 1 April 2026, provided at least 80% of the new orders they place with Openreach are full fibre where it is available. Ofcom cleared Equinox in September 2021 and its Equinox 2 overlay in May 2023, and CityFibre lost a Competition Appeal Tribunal challenge to the first decision in July 2022.

What is the reasonably efficient operator test?

It is the way Ofcom decides whether an Openreach full fibre price is fair and reasonable. Ofcom models the monthly cost per line of an efficient rival that builds its own network using Openreach's ducts and poles, which in its 2026 model is a range of £13.73 to £21.45 a month with a midpoint of £17.59. If Openreach's price leaves too little room for such a rival to recover its costs, Ofcom can intervene. The blocked offer would have taken the 160Mb rental from £17.94 to about £8.44 a month for the rebate period.

Can Openreach appeal?

Yes. An Ofcom direction of this kind can be appealed to the Competition Appeal Tribunal, and the Tribunal's rules normally require an appeal within two months of publication, which points to late November 2026. On 28 September 2026 Openreach said it would review the decision carefully and continue to engage with Ofcom, but did not announce an appeal. CityFibre's 2022 appeal against Ofcom's Equinox decision was dismissed.

Will Openreach try again with a different discount?

It can. Ofcom's rules require 120 days' notice of any conditional offer, so a revised version could not start before early 2027 even if it were notified now. Openreach said on 28 September that it believes the offer would have benefited customers and competition. Analysts at Enders Analysis, writing for ISPreview on 21 September 2026, expect Openreach could propose something similar in 2027 and argue that restrictions like this one will look harder to justify as competition grows. That is a forecast, not an Ofcom position.

Does this decision affect customers on an alternative network?

Indirectly, and mostly in their favour. The blocked offer targeted the customers alternative networks are trying to win and keep, so its withdrawal removes one source of price pressure on them. Altnets still face their own challenges: INCA reported an 18% take-up rate across altnet networks in 2025, against 40% on Openreach's full fibre, and the CMA is due to rule on the nexfibre and Netomnia merger by 15 December 2026. If you are on an altnet, the practical questions are the same as ever: your contract end date, the price after the intro period, and what happens if the company is sold.

What should I do if I am out of contract?

Switch or re-contract now rather than wait for a discount that is not coming. Ofcom's February 2026 research found customers in contract pay £7 to £9 a month less than those out of contract, and its September 2026 update put the average out of contract bundle bill at £78 a month against £69 in contract. Check which networks reach your address, compare the total contract cost including the pounds and pence rise written into most 2026 contracts, and use One Touch Switch, where only your new provider needs to be involved.
