Broadband speeds in Blackburn with Darwen

Share of premises by the fastest download speed available, averaged across every Blackburn with Darwen postcode.

Superfast availability is the number to watch here. At 95.9% of postcodes, Blackburn with Darwen falls a little short of the UK average of around 97 per cent. The gap is about one percentage point, small but real, and it means a minority of addresses still cannot order a 30 Mbps connection. At the faster end the picture is healthier. Gigabit-capable coverage reaches 84.6% of postcodes, so most households can buy far more speed than a typical family uses. The genuinely slow tail stays modest, with 0.9% of the district's 3,298 postcodes recording downloads below 10 Mbps. Taken together, the numbers describe a place where the top end is well served and the gaps sit in the middle, among addresses that clear 10 Mbps but miss the superfast threshold.

Blackburn with Darwen at a glance

Value hunters get a reasonable deal from these numbers. Because gigabit-capable coverage runs well above eight in ten postcodes, competition for faster packages exists at most addresses, and the 0.9% slow tail means very few are locked out entirely. The households most affected are those in the roughly 4% of postcodes without a superfast option, for whom the choice of packages narrows sharply. Checking the exact postcode is sensible before renting or buying in the district.
