Broadband in West Dunbartonshire

This is a fibre district first and foremost. Ofcom data puts full fibre at 85.3% of West Dunbartonshire's 2,343 postcodes, and gigabit availability sits at exactly the same 85.3%, which suggests fibre is doing the heavy lifting at the top end here. G14 and G13 lead the way with 100% coverage, and G81 follows at 89.8 per cent. The laggards are still respectable by most standards. G82 records 81.2 per cent and G60 79.7 per cent, both above the national norm. The genuine outlier is G63, where the dataset shows no full fibre at all, a reminder that even a strongly fibred district can carry a blank spot. Underneath the fibre story, the fundamentals hold up. Superfast coverage of 98.7% beats the roughly 97% UK average, so postcodes outside the fibre footprint still have fast options in nearly every case.

For households the takeaway is that fibre-grade packages are the default expectation rather than a lucky find. In six of the seven outward codes the odds of a full fibre option are high, and in G14 and G13 the data makes it a certainty. Anyone in G63 faces the opposite situation and should focus on the superfast market, which covers 98.7% of the district's postcodes.
