Broadband in Lewisham

SE9 is the borough's high-water mark, with full fibre passing 99.9% of premises, and SE15 and SE16 sit close to full coverage as well. The borough-wide figure is 88.3% for fibre and 88.1% for gigabit availability, so the two measures track each other almost exactly. Superfast is broader again at 98.6%. Not every district keeps pace. SE3 is the clear outlier, where fibre reaches around two-thirds of premises, and SE6 and SE26 also trail the borough average. Even so, the floor is high. Across 4,818 postcodes, barely any address is left below 10 Mbps, with the share at 0.4%. For a household comparing streets within the borough, the difference between districts now shows up in maximum speed and provider choice rather than in the basic existence of decent broadband.

The practical effect of these figures is choice. At 88.1% gigabit availability, most Lewisham households can pick from the full range of speed tiers and let budget decide. The exceptions cluster in SE3, where a household needing a fibre line has two chances in three rather than a near certainty, so anyone moving within the borough should compare districts before exchanging contracts.
