Barnet’s suburban streets favour larger detached and semi-detached houses compared with inner London, generally with more garden space and fewer conservation restrictions outside a handful of designated areas, which simplifies outdoor unit placement considerably.
Two trends drive a lot of enquiries locally: loft conversions and garden room extensions. Both create new living spaces that were never part of the original building’s heating and ventilation design, and both tend to overheat significantly in summer without dedicated cooling — a converted loft directly under the roofline is often the warmest room in the house by some margin.
Because many Barnet properties have more usable garden space, multi-split systems covering several rooms — including a garden office or converted loft — are common, with condensers sited discreetly at ground level or on a rear wall.
