THE £2BN CONSOLIDATION

HOW THE DEAL IS STRUCTURED

This is a complex split transaction designed to separate the physical network from the retail customers. It remains subject to CMA approval. Here is the breakdown of the moving parts according to the press release and later CMA case documents:

• nexfibre takes the network: They plan to acquire Substantial Group (Netomnia, YouFibre and brsk) for an Enterprise Value of £2bn.
• VMO2 takes the customers: If the deal is cleared, nexfibre plans to sell the retail business (YouFibre and brsk brands) to Virgin Media O2 (VMO2) for £150m.
• The Cash Injection: The owners are committing £1bn in new net funding. InfraVia is providing £850m, while Liberty Global and Telefónica are jointly contributing £150m.
• The VMO2 Windfall: In exchange for committing wholesale traffic on 4.6m homes, VMO2 would receive approximately £1.1bn in cash and an indirect 15% stake in nexfibre.

If cleared, the net effect is clear: nexfibre becomes a larger wholesale operator, while VMO2 secures the customer relationships and a substantial cash injection to deleverage.

THE NUMBERS AT A GLANCE

The figures cited in this proposed deal are significant. We have broken down the key data points from the announcement and regulatory update. Click a row to see the details.

VOICES FROM THE BOARDROOM

The leadership teams were keen to highlight the scale of this merger in their joint statement:

"By bringing our strengths together, we are creating a scaled and financially secure wholesale fibre challenger to BT Openreach – one that will enhance competition, strengthen the UK’s digital infrastructure and deliver greater choice... This transaction unlocks £3.5 billion in international investment."

— Vincent Levita (InfraVia), Mike Fries (Liberty Global) and Marc Murtra (Telefónica)

Crucially for existing customers, Jeremy Chelot, CEO of Substantial Group, added:

"Importantly, our retail brand, YouFibre, will remain post-close, ensuring our customers continue to receive the same trusted service they know today."

WHAT CHANGES FOR CUSTOMERS?

IF YOU ARE WITH YOUFIBRE OR BRSK

For now, nothing changes automatically because the transaction is still awaiting regulatory approval. If the deal is cleared, YouFibre is expected to remain as a retail brand, while the wider customer base would transfer to VMO2. For service context, read our YouFibre broadband review.

IF YOU ARE A VIRGIN MEDIA CUSTOMER

The deal identifies two specific groups of VMO2 homes. For wider context on service quality, speeds and customer experience, see our Virgin Media broadband review.

1. Adjacent Areas (2.1m homes): These are homes near the Netomnia network but currently on VMO2's older cable. nexfibre would finance the upgrade of these homes to full fibre, with most expected to be ready by the end of 2027 if the transaction is cleared.
2. Overlap Areas (2.5m homes): These are homes where both networks already exist. VMO2 would begin paying wholesale fees to use the fibre network at closing, signalling a potential faster migration from cable to fibre for these users.

For VMO2 customers, the practical upside could be faster access to full fibre in some areas, but the details depend on CMA approval, build timing and future package choices. You can compare current Virgin Media broadband deals or read our guide to Virgin Media pros and cons for a broader view.

STRATEGIC LOGIC: WHY DO THIS?

The press release makes it clear: this is about creating a "scaled, sustainable platform" to rival BT Openreach. The combined entity aims to have a full fibre footprint of around 8 million premises by the end of 2027. For wider market context, see our guide to fibre broadband in the UK.

For VMO2, the logic is asset-light expansion: it could move customers to better fibre without digging all the trenches itself, receive construction and managed-services fees from nexfibre, and receive around £1.1bn in cash to help reduce debt while retaining customer relationships. It also fits the longer history of Virgin broadband, where cable, fibre upgrades and network ownership have repeatedly shaped the brand's competitive position.

TIMELINE & NEXT STEPS

REGULATORY UPDATE: CMA PHASE 2

The biggest change since publication is regulatory. The CMA has moved the case from pre-notification and Phase 1 activity into a fast-track Phase 2 investigation.

• Status: Open CMA merger case.
• Referral date: July 1, 2026.
• Deadline: December 15, 2026.
• Why it matters: The CMA will assess whether the transaction could substantially lessen competition in UK telecoms markets, particularly where network footprints overlap.

That means the deal should be described as anticipated or proposed, not completed. Customers should not expect immediate contract, billing or network changes unless the transaction is approved and operational integration starts.
