Broadband speeds in Flintshire
Share of premises by the fastest download speed available, averaged across every Flintshire postcode.
Flintshire's numbers read well from the top down. Gigabit-capable coverage at 86.3% of postcodes puts the fastest packages within reach of the clear majority of the county, and superfast availability of 95.5% is only a shade under the UK norm of roughly 97 per cent.
The weak spots are small but real. About 1.9% of postcodes still record speeds below 10 Mbps, roughly one in fifty. No standalone full fibre figure is recorded here, and since cable networks can deliver gigabit speeds, the 86.3% describes what speeds are orderable rather than which technology carries them. Taken together, the data describes a county where a fast connection is the default. Most addresses can choose between superfast and gigabit tiers, and the deciding factor for the typical household will be monthly cost rather than availability.

Flintshire at a glance
When availability is this broad, the sensible question shifts from can I get fast broadband to how much speed is worth paying for. A household with several simultaneous streamers or a home worker moving big files will feel the benefit of a gigabit tier. Lighter users at the same address could halve their bill on a superfast deal and notice no difference. The 1.9% of slow postcodes are the exception worth ruling out before exchange of contracts.
