Heat and planning around Washington
In Washington last summer (2026) there were ≈2 nights that stayed above 18 °C — 5 times the 1991–2020 average of 0.4 (ERA5 reanalysis, grid ≈30 km, lower than street temperatures in cities). The figure is the household-weighted mean of 3 postcode districts where these offices are registered.
2% of sampled postcodes in Washington sit in a conservation area (2,156 live postcodes across 3 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.
