What homes around N1 need

In N1 last summer (2026) there were ≈10 nights that stayed above 18 °C — 5 times the 1991–2020 average of 1.9 (ERA5 reanalysis, grid ≈30 km, lower than street temperatures in cities).

56% of sampled postcodes in N1 sit in a conservation area (on-record, 2,282 live postcodes).

In England an air-source heat pump on a house can be permitted development under Class G when the conditions hold, including the MCS 020a noise limit of 37.0 dB(A) (§3.2 Step 8).

Companies House snapshot 1 Sep 2026, retrieved 25 Sep 2026. The address shown is the registered office, not a verified operating base. This catalogue is a directory of incorporated businesses, not an exhaustive installer register. Hot nights: ERA5-ARCO for N1, June–August, minimum at or above 18 °C, retrieved 25 Sep 2026. Conservation-area share: sampled postcode points in N1, snapshot 25 Sep 2026.

Better than a town-wide list: these are the registered offices in N1, with that district's hot nights and planning rule.
