Broadband speeds in LL78
Share of LL78 premises by the fastest download speed available, averaged across all 22 postcodes in the district.
An isolated zone relying heavily on wireless. Wireless services are available to 57.9%, exceeded only by LL76, indicating a remote or fibre-light area. Superfast covers 83.9%, with gigabit at 25.4%. Below-superfast hits 12.4%, and below-USO reaches 8%, the highest in the batch. The constellation of high wireless, high below-USO, and low gigabit paints a picture of delayed fibre rollout with heavy reliance on wireless alternatives. Most premises depend on wireless or copper connectivity. Gigabit access is limited. The 8% below-USO rate indicates copper-era speeds persist. The high wireless dependency and widespread below-USO coverage suggest ongoing infrastructure challenges. Households here face less choice and less consistent performance than better-served areas. Future-ready broadband is not yet available. Current service is adequate for basic needs but may frustrate demanding users.
