OFNL completes integration of FibreNest’s UK full fibre broadband network

Alternative full fibre operator Open Fibre Networks (OFNL), which serves developments of new build homes, have notified their broadband ISP partners across the UK that they’ve completed the integration work for FibreNest‘s network. In other words, retail ISPs on both sides of the network are now starting to gain access to each other’s fibre infrastructure.

Just to recap. BUUK Infrastructure (Open Fibre Networks Limited) originally acquired FibreNest from Persimmon Homes for a discounted total enterprise value of c. £100m back in May 2025 (here). At the time of the deal, OFNL covered an estimated 170,000 premises and FibreNest reached around 54,000 with their respective gigabit broadband networks.

The deal meant that FibreNest would ultimately become just another retail ISP on the combined network alongside OFNL’s other retail partners, although physically integrating the Fibre-to-the-Premises (FTTP) infrastructure from two different operators is often a slow, complex and costly process.

OFNL recently confirmed to their ISP partners that they have “now started to add FibreNest plots onto the OFNL Address base“. The first such site (has a postcode area outcode of IP9) appears to have been added last week and “further sites will be added over the next few weeks” (credits to one of our readers, Dale, for spotting this).

As a result OFNL’s other ISPs, such as seethelight, internetTY, 1310, Direct Save Telecom and many more, should now be able to place orders for services on the OFNL Portal or the OFNL API for these addresses connected to the FibreNest network. However, ISPreview understands that OFNL’s Portal doesn’t yet fully support everything ISPs may need once customers are connected, but that will also be resolved in the “next few weeks“.

The downside is that much of this newly consolidated network will still often exist on new build property developments where there are no other rival FTTP networks to OFNL’s infrastructure.
