Trusted HIU & MVHR Engineers Across Haringey
Haringey was an early adopter of district heating in London. Hale Village at Tottenham Hale was one of the capital's first large-scale developments built around a communal energy centre, and the wider Tottenham Hale regeneration has since added thousands more flats served by Heat Interface Units.
Collide Group provides specialist HIU and MVHR service, repair, installation and powerflush across the whole Haringey borough — from the new-build towers at Tottenham Hale to the converted and mid-rise stock around Wood Green and Hornsey.

HIU & MVHR Engineering in Haringey — A Local Guide
Haringey's housing stock is unusually mixed, and that shapes the work we do here. Tottenham Hale and Wood Green are dominated by newer network-connected apartment blocks with HIUs, while Crouch End, Muswell Hill and Hornsey hold far more period conversions.
Because Hale Village and the surrounding developments are now well over a decade old, we see a high proportion of age-related HIU faults in this part of the borough — scaled plate heat exchangers, worn diverter and control valves, failed actuators and units that have simply never been serviced. Brands across Haringey include Danfoss, SAV, Switch2 and Caleffi.
The newer Tottenham Hale blocks also rely on MVHR for ventilation. These units need annual servicing and a filter change every 6 to 12 months — London's traffic pollution clogs filters quickly, and once airflow drops, condensation and mould follow. We service MVHR from £120.
