Broadband in Harlow

The gigabit figure does the talking here. At 79.5 per cent of postcodes, gigabit-capable coverage is broad, yet the dataset records no matching full fibre share, a pattern consistent with cable network coverage rather than a complete picture of what is in the ground. Superfast availability reaches 94.7 per cent, slightly under the UK norm of about 97 per cent. The tail matters more. Some 1.5 per cent of postcodes cannot get 10 Mbps, a small share but a frustrating one if your address is in it. With only four outward codes, CM17, CM18, CM19 and CM20, conditions do not swing much across town in the recorded figures, so the postcode-level pages are where the exceptions show up. That combination, wide gigabit reach alongside a thin slow tail, is the whole Harlow story in the current data.

A household picking an address in Harlow faces decent odds. Roughly four postcodes in five sit within gigabit-capable coverage, and superfast is close to universal. The 1.5 per cent stuck below 10 Mbps is the group with a real decision to make, since no ordinary fixed line there will comfortably handle modern use. Confirming a specific postcode before exchanging contracts is cheap insurance.
