Trusted HIU Engineers Across Greenwich

Greenwich has significant new-build development along the Thames, with Woolwich Arsenal and Greenwich Peninsula among the most prominent district heating zones in south-east London. Both schemes rely heavily on HIUs to deliver heating and hot water to thousands of flats across their respective residential towers and low-rise blocks.

Collide Group provides specialist HIU service, repair, installation and powerflush across the whole Greenwich borough. Our manufacturer-trained engineers carry parts for all major HIU brands and aim to resolve the majority of faults on the first visit.

HIU Engineering in Greenwich — A Local Guide

Greenwich borough has become a focal point for Thames-side residential development. The Greenwich Peninsula masterplan — one of the largest regeneration projects in Europe — has delivered thousands of new homes connected to a district heating network, with an HIU in every flat. Woolwich Arsenal, the former Royal Arsenal site, similarly features large-scale communal heating infrastructure across its mixed-tenure development.

Common HIU brands found in Greenwich buildings include Danfoss, SAV, Caleffi and Thermal Integration. New developments on the peninsula tend to feature the latest generation of compact, high-efficiency HIUs, while older regeneration stock at Woolwich may have units approaching the end of their service life.

Our engineers are familiar with the Greenwich building stock — from the Peninsula towers to the Woolwich Arsenal conversions and the Thamesmead estate. We carry common replacement parts on the van so most first-visit fixes are possible without a return trip.
