Edwardian and 1930s houses with real plots, which makes this one of the easiest places in London to install properly. The conservation area around the Green is the exception.

A job we did in N21
Winchmore Hill N21
Air source heat pump with roof-mounted solar
The panels sit across the rear pitch and the heat pump at the side of the house, which is the pairing that lets the pump run on its own generation through the middle of the day.
What the housing in Winchmore Hill means for the job
Winchmore Hill is the kind of housing stock that makes an installer's job straightforward: Edwardian and interwar semis and detached houses with side access, gardens deep enough that an outdoor unit is nowhere near a boundary, and plenty of room for a proper base. Rooms are generous, which usually means a 3.5 kW unit where a smaller house would take 2.5 kW. The exception is the conservation area around Winchmore Hill Green and the older streets near it, where anything visible from the road needs thinking about first.
Worth knowing before you book. Loft conversions are common here and they are consistently under-sized by installers working off floor area alone. A converted loft under a slate roof gains heat all afternoon and needs the next unit size up.

Everything we do in N21
Cooling is most of it. Since 2026 the same machine also heats, and we fit the renewables side too.
Installation
Wall units, ceiling cassettes and concealed ducted, one room or a whole house.
Servicing
Annual service from £95 plus VAT, any make, whoever fitted it.
Repair
£89 plus VAT to diagnose, waived if we do the work.
Heating too
The same unit is an air-to-air heat pump. It heats at three to four times the efficiency of an electric heater.
Winchmore Hill sits in Enfield, and the borough page covers the rest of it. All the areas we cover.
Air conditioning in Winchmore Hill: common questions
I am in the conservation area near the Green. Can I still have it?
Usually yes, but not under permitted development if the unit would be visible from the road. That means a planning application rather than a refusal.
We survey with that in mind and design for a position that avoids the problem where one exists. The conditions are here.
Can one outdoor unit serve the whole upstairs?
Up to a point. One condenser can run several indoor units, but every room still needs its own unit and the condenser has to be sized for all of them running at once.
The difference between a single split and a multi-split, and what each costs.
How close are you?
We are in N14, so N21 is about five minutes. This is the closest work we do and it is usually the quickest to book.
Surveys here are often the same week.
