Broadband in Richmond upon Thames

SW14 tops the borough's fibre table, with just under nine postcodes in ten able to order full fibre, and SW13 follows at 87%. SW15 drops to about two in five. Then comes the cliff edge: KT1, KT2 and KT8 all show zero full fibre in the data, an unusual gap for a borough whose overall figure is 79.8%.

The zeros overstate the problem for actual speeds. Gigabit-capable coverage across all sixteen outward codes runs at 87.4%, so plenty of addresses without fibre can still buy gigabit over other networks. Superfast availability is 97.8%, a shade above the national average, and only 0.2% of the 4,247 postcodes fall below 10Mbps. Anyone weighing an SW address against a KT one is really choosing between technologies, not between fast and slow.

House hunters comparing the borough's postcodes get a rare luxury: the floor is extremely high everywhere. A 0.2% below-10Mbps share is close to nothing across 4,247 postcodes. The meaningful difference sits at the top end, where SW14 and SW13 offer near-universal full fibre and the KT codes rely on alternatives. For most households that difference will not show in day-to-day use, but anyone with a strong preference for a fibre line should weight SW14 and SW13 accordingly.
