Heat and planning around Norwich

In Norwich last summer (2026) there were ≈9.4 nights that stayed above 18 °C — 5 times the 1991–2020 average of 1.8 (ERA5 reanalysis, grid ≈30 km, lower than street temperatures in cities). The figure is the household-weighted mean of 17 postcode districts where these offices are registered.

15% of sampled postcodes in Norwich sit in a conservation area (12,673 live postcodes across 17 districts).

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, June–August, minimum at or above 18 °C, household-weighted across the districts where these offices are registered, retrieved 25 Sep 2026. Conservation-area share: sampled postcode points, snapshot 25 Sep 2026. Distances are an equirectangular approximation to 0.1 km.

Better than a town directory that only lists names: each plumbing company links to its Companies House record and the local hot-night count.
