Broadband Altnet Fibrus Surpasses 30 Percent UK Full Fibre Take-up

Infracapital-backed alternative broadband ISP Fibrus, which is building a full fibre network across parts of Cumbria (England) and Northern Ireland, recently revealed that their Fibre-to-the-Premises (FTTP) infrastructure had now achieved a customer take-up of 30% (up from 28% in March 2025) – we make that roughly 135,000+ subscribers.

The operator’s full fibre infrastructure currently covers over 450,000 UK premises (up from 440k in Sept 2025), mostly in Northern Ireland where their roll-out has largely completed. But their most active build is currently focused on rural parts of Cumbria (they’ve already reached well over 100k premises in that county), which reflects a mix of both commercial build and publicly funded work via their Project Gigabit contract in the same region (Lot 28).

“We’re delighted to reach 30% customer take-up across our Full Fibre network – one of the highest rates among alt nets – a clear sign that more people are choosing faster, more reliable broadband built for modern life in the areas we serve,” said Fibrus in a brief statement earlier this month.

New customers to the service currently pay from £22.99 per month for an unlimited 159Mbps (34Mbps upload) package with an included router and free installation, which rises to just £34.99 per month for their top 982Mbps (310Mbps upload) tier on a 24-month contract term. Fibrus are currently offering the first 3 months of service for free, although service discounts may vary between different parts of their build.
