DG4 broadband and area guide

Gigabit via cable reaches 59.9% of postcodes, reflecting concentrated infrastructure investment in core settlements. Superfast (30-300 Mbps) covers 37.8%, whilst 0.7% fall short of the 10 Mbps floor. Below-10-Mbps postcodes number roughly three out of 171. Speed tiers sit at the two ends of the range in DG4, with few premises on intermediate speeds. Most premises either reach gigabit cable or face the superfast ceiling of 300 Mbps. Investment has followed density; peripheral areas remain on older superfast infrastructure. For the vast majority, speed adequacy poses no concern. Residents targeting gigabit connectivity should note that availability is concentrated in specific postcodes.. Fibre deployment forms the gigabit foundation, extending to postcodes where cable infrastructure remains incomplete. Postcode location determines whether households access gigabit or superfast infrastructure.

97.6% meet the superfast threshold or better, well above the UK average of 97% on superfast. The 0.7% below 10 Mbps represents a small isolated tail; for most residents, speed is not a limiting factor.
