Trusted HIU & MVHR Engineers Across Hillingdon
Hillingdon is our closest borough — our base is in Northolt, UB5, just minutes from Hayes and Uxbridge. That means we can typically reach Hillingdon properties faster than anywhere else in London, which matters when a flat has no heating or hot water.
The borough has seen major residential regeneration, particularly around Hayes, where former industrial sites like the Old Vinyl Factory and the Nestlé factory have been converted into large residential developments served by communal heating networks with Heat Interface Units.

HIU & MVHR Engineering in Hillingdon — A Local Guide
Hayes has been transformed over the last decade. The Old Vinyl Factory — once the EMI record works — and the former Nestlé factory site have delivered thousands of new apartments, many connected to communal heating with an HIU in each home. The arrival of the Elizabeth line has accelerated development right along the corridor.
Because we are based in Northolt, Hillingdon is effectively our home patch. We know the local building stock well and carry the parts that the developments around Hayes, Uxbridge and West Drayton typically need. Common brands here include Danfoss, SAV, Caleffi and Switch2.
The converted factory developments in Hayes are built to modern standards and ventilated by MVHR. These systems are frequently overlooked entirely by residents until condensation or mould appears. We service MVHR from £120 and can combine it with an HIU service on the same visit.
