What question is Ofcom trying to answer?

Ofcom is deciding whether Openreach can use a targeted full-fibre discount without making it unreasonably difficult for rival networks to win the same new customers. Openreach has significant market power in wholesale broadband, so certain commercial offers receive advance regulatory scrutiny. On 28 July, Ofcom said it was provisionally minded to direct Openreach to withdraw the Incremental New to Openreach Customer Offer. This is a consultation, not a completed prohibition: responses close at 5pm on 27 August and Ofcom expects a final decision by the end of September.

The discount rewards growth above a baseline

The proposed six-month national offer would apply to qualifying new full-fibre orders from 1 October 2026. An internet service provider exceeding a quarterly target based on its April volumes could receive a £35 connection rebate and a £9.50 monthly rental rebate on incremental lines. The monthly rebate would last for 18, 24 or 30 months depending on how far volumes rose above the baseline. Smaller providers with fewer than 1,000 relevant April orders would receive rebates under a different structure. The design matters because it concentrates the strongest price benefit on the additional customers that Openreach and alternative networks are competing to supply.

Ofcom’s concern is the long game

A discount can help an ISP lower costs and encourage full-fibre take-up. Ofcom’s provisional concern is that rival networks may have to match a targeted price that does not let a reasonably efficient operator recover its costs. Those networks need new wholesale customers to fill infrastructure they have already built and to justify further investment. If a dominant network wins that contest through pricing rivals cannot sustainably follow, consumers could see less network choice and weaker pressure on price and service later. Ofcom says this would be the first time it has stepped in to block an Openreach commercial offer.

The disagreement is narrower than it looks

Openreach told Ofcom that the offer’s structure does not create a barrier to using rival networks because the price paid for Openreach volumes does not change according to how many lines an ISP places elsewhere. Its public response, reported by Reuters, says the proposal was made in good faith while households are watching bills and argues that regulation should not protect weak business models. Ofcom itself rejected some wider objections to the offer’s conditional structure. Its proposed intervention instead rests principally on whether the discounted price is fair and reasonable in current market conditions.

Not every Openreach offer is being stopped

Ofcom is not proposing action against the other notified FTTP and Ethernet offers. These include a one-off £50 geographic incentive in areas where Virgin Media operates and an arrangement intended to make higher-speed packages more attractive to internet service providers. The regulator’s provisional view is that their effective discounts are smaller and unlikely to prevent a reasonably efficient rival from competing. That distinction is important: this is a targeted competition assessment, not a general ban on Openreach discounts.

What UK readers should watch next

No household needs to change provider because of this consultation, and there is no reliable basis yet for predicting a retail bill reduction or increase. The useful signals will be Ofcom’s final decision, the evidence it publishes about reasonably efficient network costs and any revision Openreach makes to the offer. The wider test is whether Britain can convert broad full-fibre availability into adoption while preserving enough infrastructure competition to discipline prices after the build phase. Short-term discounts and long-term choice are both consumer interests; the regulator now has to show why its final balance is proportionate.
