TN22 broadband and area guide

Cable gigabit infrastructure has reached 61.6% of TN22's 971 postcodes across Lewes, a substantial achievement for a rural postcode area. Superfast availability at 93.3% is close behind the national average of 97%, suggesting most premises benefit from modern fixed-line investment, even if ultrafast gigabit remains concentrated. The speed tier breakdown is revealing: 61.6% have access to 300 Mbps or higher through cable networks, 31.7% cluster in the 30 to 300 Mbps superfast band, and just 1.3% dip below superfast into basic broadband. The universal service gap is minimal at 0.4%, meaning almost all postcodes meet the 10 Mbps legal floor. Residents choosing between locations in TN22 will generally find gigabit or solid superfast available, with only a tiny fraction of postcodes at risk of sluggish service. The 6.7% gap between superfast and gigabit availability suggests infrastructure investment is active but spotty.

TN22's postcode spread reveals uneven infrastructure rollout typical of rural districts receiving selective cable investment. The 93.3% superfast coverage indicates that areas without gigabit cable usually have traditional fixed-line fibre or copper reaching superfast speeds. Postcodes in the 6.7% below superfast are concentrated in the district's most remote corners.
