Broadband speeds in Sefton

Share of premises by the fastest download speed available, averaged across every Sefton postcode.

Superfast speeds are available at 98% of Sefton postcodes, a shade above the national norm of roughly 97%. Gigabit-capable connections reach 79.5%. Full fibre, at 78%, is the figure that separates the borough from much of the country, where the comparable average sits nearer 69% of premises passed. That margin matters for anyone comparing areas before a move.

Coverage is not spread evenly. L10 leads, with fibre recorded at 97.4% of its postcodes, and L21 and L23 follow at around 97%. L70, L75 and PR8 show no recorded full fibre in this dataset. Substandard speeds are vanishing: barely 0.1% of postcodes remain below 10 Mbps. Nearly all premises face a choice between speed options rather than searching for adequate connectivity.

Sefton at a glance

The value story here rests on the speed mix rather than prices. A household can plan around fibre being the default rather than the exception, so multi-room streaming, video calls and large uploads are realistic asks at most addresses. The caution is the trio of outward codes with no recorded fibre. An address in L70, L75 or PR8 may still connect well, but the borough-wide 78% figure cannot be assumed there.
