Broadband in Merton

The basics here are close to their ceiling. Superfast at 99.2% clears the national average of roughly 97 per cent, gigabit-capable service reaches 94.1% of postcodes, and the below-10 Mbps tail is down to 0.2%, effectively a handful of addresses out of 3,500. Full fibre is where the internal contrast appears. Overall availability is 66.3%, in line with the UK figure of around 69 per cent of premises passed, but the split by outward code is stark. SW16, SW20 and SW18 all show near-complete fibre availability in the data. CR4, KT3 and SM3, by contrast, record none at all, leaving those codes reliant on the cable network for their gigabit options. Ten outward codes in total feed the averages. For an individual address the outward code is the strongest single clue to what will be on offer.

Practically speaking, nobody in Merton needs to worry about the floor. A 0.2% sub-10 Mbps share means slow addresses are vanishingly rare, and 94.1% gigabit coverage keeps top-tier options open almost everywhere. The choice that matters is technology. Addresses in the fibre-rich SW codes can pick full fibre products, while CR4, KT3 and SM3 households will be choosing among cable-based gigabit services instead. Same headline speeds, different networks.
