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.
