Grain Deploying UK Full Fibre Broadband Network to Doncaster in South Yorkshire

Carlisle-based broadband ISP Grain (Grain Connect), which has already built their 2Gbps speed point-to-point full fibre (FTTP) network to cover 270,000 UK premises (aiming for 600,000 in the future) and in 2025 secured a £225m funding boost (here), appears to have confirmed that they’ve started a new roll-out across the South Yorkshire city of Doncaster.

At present Doncaster, which is home to a population of over 87,000, already has wide access to three gigabit-capable broadband networks via Openreach, Virgin Media (inc. nexfibre) and CityFibre. In addition, there’s also a small bit of full fibre coverage from alternative networks like Hyperoptic, OFNL, Quickline and possibly others. Suffice to say, it seems like a risky bet for an altnet like Grain Connect, but that’s not stopped them before.

According to Business Doncaster, the local roll-out technically began in June 2026 and the first customers are set to be connected this Autumn 2026. “We’re excited to offer Doncaster residents an internet service that can keep up with their digital lives,” said Richard Cameron, CEO of Grain broadband. The City will thus soon join some of Grain’s other haunts across Yorkshire, including parts of Bradford, Castleford, Goole, Grimsby, Halifax, Huddersfield, Hull, Leeds, Scarborough and Sheffield.

ISPreview had a closer look at Doncaster and identified that Grain’s initial deployments appear to be taking place across various streets just above and below Balby Road, which leads into the city centre. As usual, Grain intends to try and undercut the established networks on price, with early sign-ups during July 2026 being offered symmetric package speeds from £19.99 per month for 250Mbps (four months of free service is also being promoted for faster speeds). All packages promise no in-contract price rises, no installation fees, and a Price Match Guarantee.
