Broadband in Hertsmere

Start at the bottom of the market, because it is nearly empty. Just 0.9 per cent of postcodes here fall under 10 Mbps. Superfast coverage stands at 96 per cent, a fraction below the national norm of about 97 per cent, close enough that the difference means little in practice.

The gigabit figure of 83.9 per cent carries more consequence for households choosing a package. The recorded full fibre share is zero, including across the listed codes EN4, EN5 and EN6, so the data supports describing that gigabit footprint as cable network coverage and nothing more specific. Roughly five postcodes in six can reach the top tiers on the recorded figures. The rest wait, and the town-level data gives no way of telling which outward codes they cluster in.

The mix suits ordinary households well. A 96 per cent superfast share means the 30 Mbps floor is met almost everywhere, and the 0.9 per cent slow tail is small. Heavier users face a simple split: inside the 83.9 per cent gigabit footprint the fastest packages are on the table, outside it superfast is the ceiling for now.
