HIU Engineering in Croydon — A Local Guide
Croydon is south London's principal commercial and residential centre, and has been the subject of sustained regeneration investment over recent years. The town centre has seen significant new residential development with blocks connected to communal heating networks — the standard approach for modern large-scale residential in this part of London.
Common HIU brands found in Croydon buildings include Danfoss, SAV, Caleffi and Switch2. New-build developments in the town centre and along the tram corridor tend to have the latest generation of compact HIUs, while older stock in Thornton Heath and Norbury may have units approaching the end of their service life.
Our engineers cover the full extent of the Croydon borough — from the new-build towers in the town centre to the housing association estates in Thornton Heath and Selhurst. We carry common replacement parts on the van so most first-visit fixes are possible without a return trip.
