In a significant move that could reshape the UK’s digital infrastructure landscape, Liberty Global has partnered with Spain’s Telefónica and French private equity firm InfraVia Capital Partners to acquire UK-based fibre broadband provider Substantial Group for approximately £2 billion.
The acquisition will be executed through their existing joint venture, nexfibre, and is being viewed as one of the most important infrastructure deals in the UK telecom sector this year.
Deal Structure and Key Highlights
This is not just a standard acquisition—it is part of a long-term infrastructure expansion strategy.
🔹 Deal Value

How effectively these challenges are managed will determine the long-term success of the deal.
