DGN GAS installs air conditioning across Hampstead (NW3) — discreet, quiet split and multi-room systems that cool period homes and mansion flats in summer. F Gas qualified, and experienced with the conservation, listed-building and freeholder rules that come with NW3. Free no-obligation quote.
Hampstead’s Georgian and Victorian period homes — solid walls, big windows, south-facing rooms — can get uncomfortably warm in summer, and a well-designed air conditioning system fixes that quietly. We install wall-mounted split systems for a single room and multi-split systems that cool several rooms from one discreet outdoor unit, with slim, tidy pipework runs.
Every system is sized to the room and the property rather than guessed, installed by F Gas qualified engineers, and finished cleanly — which matters in homes where appearance is everything. Modern units run very quietly and double as efficient heating in the cooler months.
The catch in Hampstead is rarely the cooling — it’s the permission. Much of NW3 is conservation area with Article 4 restrictions, and many homes are listed, so an external condenser unit usually needs planning permission rather than falling under permitted development. In a mansion flat you’ll also need freeholder or managing-agent consent.
We plan the condenser siting and pipework to be as discreet and compliant as possible — out of sight of protected frontages, sympathetic to the building — and advise on where consent is needed before any work starts. Getting this right first time is the difference between a smooth install and a planning headache.
Around the village, Frognal and Belsize Park the stock is grand villas, period townhouses and mansion-block flats, each with its own siting challenge. On a house with a garden we can often place the unit discreetly at the rear; in a flat we work with the available external space, lightwells or roof areas, and the building’s rules.
We’re used to the standards Hampstead clients expect: a quiet system, an outdoor unit kept as invisible as possible, clean interior fitting and a tidy site throughout.
