HIU Engineering in Lewisham — A Local Guide
Lewisham has seen consistent regeneration investment over the past decade. The Lewisham Gateway scheme has brought hundreds of new flats into the borough's HIU stock, and ongoing development at Deptford and New Cross continues to add to the total. These new-build developments rely on communal energy centres with HIUs providing the interface to each individual flat.
Common HIU brands found in Lewisham buildings include Danfoss, SAV, Caleffi and Switch2. The mix of new-build developments and converted ex-social housing means engineers need to be familiar with both the latest generation of compact HIUs and older units that may require servicing or replacement.
Our engineers are well versed in the Lewisham building stock — from the Gateway towers to the Deptford riverside developments and the older housing association estates in Catford and Forest Hill. We carry common replacement parts on the van so most first-visit fixes are possible without a return trip.
