Openreach Price Cuts: Ofcom Review and £3.5bn Fibre Warning Explained

OPENREACH PRICE CUTS: KEY VERIFIED FACTS

WHAT IS OFCOM ACTUALLY REVIEWING?

“Openreach price cuts” is useful search shorthand, but the official description is more precise: Ofcom is considering four proposed wholesale pricing arrangements.

1. INCREMENTAL NEW TO OPENREACH CUSTOMER OFFER

This applies to Openreach FTTP wholesale services and is conditional on the volume or range of services purchased. It is notified to begin on 1 October 2026.

2. INCREMENTAL NEW OPENREACH CUSTOMER OFFER IN VMO2 AREAS

This FTTP offer overlays the first offer in areas associated with Virgin Media O2. It is both conditional and geographic. Openreach has applied for Ofcom's consent because the location-based element would otherwise fall within restrictions on geographic discrimination. It cannot take effect in that form without consent.

3. INCREMENTAL ETHERNET NET DEMAND OFFER

This applies to Openreach Ethernet wholesale services and is conditional on purchasing volume or range. Ethernet is primarily relevant to business and network connectivity rather than ordinary home broadband packages.

4. SIX-MONTH EXTENSION TO THE EQUINOX 550MB INCENTIVE

This extends an incentive covering Openreach's 550Mb FTTP wholesale rentals under Equinox 1 and 2. It is also notified to begin on 1 October 2026.

Ofcom is asking whether the conditional offers require early intervention, whether the geographic offer should receive consent, and whether any offer raises concerns about excessively low pricing or discrimination capable of harming competition.

WHAT DOES THE £3.5BN FIBRE INVESTMENT CLAIM REALLY MEAN?

The £3.5bn figure comes from the February announcement of nexfibre's proposed acquisition of Substantial Group. A footnote defines it as projected nexfibre capital expenditure between 2026 and 2040 resulting from the transaction.

That makes it a long-term, forward-looking estimate. It is not the purchase price, not an amount already spent and not a pot of cash that has been formally withdrawn. The transaction itself has a £2bn enterprise value, while the owners also announced £1bn of new net funding to finance the deal.

InfraVia partner Bruno Candès later told The Times that the future investment path depends on active enforcement of Ofcom's competition framework. That is an investor warning and a statement of commercial position. It should not be rewritten as “Ofcom has put £3.5bn at risk” or “£3.5bn has been cancelled”, because neither claim has been established.

The underlying concern is take-up. Fibre builders spend heavily before earning subscriber revenue. If large internet providers keep most new customers on Openreach because of conditional or localised incentives, a competing network may struggle to reach the utilisation needed to support further construction.

Openreach's counterargument is equally relevant: lower prices are a normal response to competition and can benefit providers and customers. Ofcom now has to test evidence from both sides.

THE NEXFIBRE, SUBSTANTIAL GROUP AND NETOMNIA DEAL EXPLAINED

nexfibre is a wholesale-only fibre network jointly owned by InfraVia, Liberty Global and Telefónica. On 18 February 2026, the partners announced an agreement for nexfibre to acquire Substantial Group at an enterprise value of £2bn.

Substantial Group includes the Netomnia fibre network and the YouFibre and Brsk retail businesses. Under the announced structure:

• nexfibre would acquire Substantial Group and retain the fibre infrastructure;
• the YouFibre and Brsk retail operation would be sold to Virgin Media O2 for £150m;
• Virgin Media O2 would commit wholesale traffic across 4.6m overlapping and adjacent premises; and
• nexfibre would finance fibre upgrades to 2.1m adjacent Virgin Media O2 cable premises.

The companies project that nexfibre, Netomnia and the planned upgrades will create an approximately eight-million-premises full-fibre footprint by the end of 2027. The announcement also says nexfibre and Virgin Media O2's growing fibre networks would collectively reach 20m premises.

The competition review must also be described carefully. The CMA case is open, but its latest page says the transaction remains in pre-notification and that a formal Phase 1 investigation has not yet been launched. Completion is still described by the parties as expected in the third quarter of 2026, subject to regulatory approvals.

WHY OPENREACH SAYS IT MUST BE ALLOWED TO COMPETE

Openreach's position is that network competition cannot mean rivals are free to cut prices while the largest network is prevented from responding. Chief executive Katie Milligan said Ofcom has recognised that Openreach should be allowed to compete and that the company intends to keep improving its network and offers.

That argument has consumer force. Lower wholesale charges can help internet providers make FTTP packages more attractive, reduce the premium for faster speeds or offer stronger switching incentives.

But Openreach is regulated because Ofcom has found BT to possess significant market power in relevant wholesale fixed-access markets. A nationwide network with deep ISP relationships may be able to structure discounts in ways that a smaller builder cannot replicate.

The correct regulatory question is not “should Openreach ever cut prices?” It is whether each specific offer represents fair competition or creates loyalty, volume or geographic effects that make an efficient rival unable to recover its costs.

COULD OPENREACH PRICE CUTS MAKE BROADBAND CHEAPER?

Potentially—but not automatically. These are wholesale offers for communications providers. A provider might use a saving to reduce a monthly price, offer cashback, waive an activation fee, include free months or make a 500Mbps upgrade more attractive.

It could also retain some of the benefit to cover equipment, support, marketing and other costs. Existing customers should not expect their direct debit to fall simply because an Openreach offer begins.

The most visible effects are likely to appear in new-customer promotions, renewal negotiations and upgrades where several networks are competing for the same household. Our earlier analysis of how Openreach full-fibre discounts could affect broadband prices explains why the retail outcome depends on each provider.

There is also a longer-term trade-off. A fair reduction can improve value and accelerate FTTP adoption. A discount that removes viable infrastructure rivals could reduce choice after the promotional period ends. Ofcom's assessment therefore has to consider both immediate price benefits and future network competition.

WHAT SHOULD CUSTOMERS DO NOW?

Compare the full contract cost at your address. Check setup fees, scheduled price changes, minimum speeds, router terms, contract length and the price after the minimum term. Being out of contract generally gives you the strongest negotiating position.

OPENREACH'S FIBRE GROWTH AND LINE LOSSES

BT's results for the year to 31 March 2026 show why Openreach wants commercial freedom. Its FTTP footprint reached 23m premises, and BT said it remained on track for 25m by the end of December 2026.

Openreach also added 2.2m net new full-fibre connections during the year, taking connected FTTP premises to 8.8m. At the same time, it reported 825,000 broadband line losses across the wider network.

Those figures are not contradictory. Openreach can migrate many customers onto its own FTTP platform while losing other wholesale lines to cable networks, alternative fibre operators, product changes or disconnections.

Our detailed breakdown of Openreach's 2.2m fibre connections and 825,000 line losses explains the difference between network expansion, take-up and wholesale line loss.

The numbers confirm that competition is real, but they do not determine whether the four proposed offers are fair. That requires offer-level evidence on price, conditions, geography and likely ISP behaviour.

WHAT HAPPENS NEXT?

Ofcom has a 120-day notification period for the conditional offers. It says the short initial-response window is intended to leave time for analysis and any consultation on provisional views.

Separately, the CMA's nexfibre/Substantial case remains open. Its latest published timetable lists the formal Phase 1 launch and decision deadline as “TBC”. The Ofcom pricing review and CMA transaction process are distinct, even though both affect the future structure of UK fibre competition.

OUR VERDICT

The accurate headline is that Ofcom is reviewing four Openreach wholesale offers while InfraVia argues that effective competition rules are important to the investment case behind nexfibre.

It is too early to say the offers are anti-competitive. Ofcom has not reached a provisional view, and a lower wholesale price can be a legitimate and useful response to rival networks.

It is also inaccurate to say £3.5bn has already been lost. That figure is projected nexfibre capex through 2040 arising from a transaction that has not completed.

The substantive issue is whether conditional and geographic terms give customers better value without preventing a reasonably efficient competing network from winning enough demand to survive. That is the evidence Ofcom now needs to test.

For households, the practical advice is unchanged: compare every live network and provider available at the exact address, because local competition matters more than national headlines.
