Fibrenest and OFNL

Fibrenest is a full-fibre broadband provider that was established in 2018 by housebuilder Persimmon Homes. It delivers fibre-to-the-property (FTTP) connections to new-build homes across England, Wales, and Scotland, covering approximately 54,000 premises.

Unlike the OFNL network, where customers can choose from multiple providers, Fibrenest developments were locked to a single provider: Fibrenest itself. This gave customers no choice of ISP and limited competitive pressure on pricing and service quality.

The Acquisition

In August 2025, BUUK Infrastructure — the company that operates the OFNL network — acquired Fibrenest from Persimmon Homes for a total enterprise value of £100 million (£70 million on completion, with additional contingent payments based on business performance).

The acquisition brings together two complementary fibre networks. OFNL previously covered around 170,000 premises; adding Fibrenest’s 54,000 significantly expands the combined footprint. Crucially, BUUK operates an open-access model, meaning multiple ISPs can offer services over the same physical infrastructure — a fundamental shift from Fibrenest’s single-provider approach.

What This Means for Fibrenest Customers

The most significant change is choice. Fibrenest customers will gain access to the same range of ISPs available on the OFNL network — currently up to 21 providers — rather than being locked into Fibrenest as their only option.

Work is underway to open up the former Fibrenest network during 2026, allowing customers to switch providers. In the meantime:

  • Existing Fibrenest contracts, pricing, and support channels remain unchanged during the transition.
  • Fibrenest has applied a price freeze until April 2027 at the earliest.
  • Pre-registration is available for customers interested in switching to an alternative ISP once the network opens.

What This Means for Existing OFNL Customers

For those already on the OFNL network, the acquisition doesn’t change your service or provider options. The same providers and packages remain available.

The expanded network footprint does strengthen OFNL’s position as an infrastructure provider, which could attract more ISPs to the platform and lead to increased competition and better deals over time.
