A job we did in E11
Leytonstone E11
Samsung monobloc air source heat pump
On its own slab set clear of the fence line, with the condensate taken away below ground level instead of being left to run across the paving and freeze.
We install, service and repair air conditioning across Leytonstone E11. A single room is £2,400 to £3,200 fitted and a whole house is £8,400 to £11,300, with a free survey and a written price that does not change.
A single unit in a rear bedroom or a converted loft, condenser at ground level in the side return or on the kitchen extension roof. One day on site.
What the housing in Leytonstone means for the job
Leytonstone is largely late Victorian terraced housing, and the side return is the defining feature: most of these houses have one, most of them have had it built over or partially built over, and where the outdoor unit goes depends on which. Where the side return is intact, a ground-level position on a slab clear of the fence line is the answer, which is the job in the photograph above. Where it has been built over into a kitchen extension, the position moves to the rear elevation or onto the flat roof of the extension itself. Bushwood and the streets around it form a conservation area, which closes the permitted development route for anything visible from the road.
Worth knowing before you book. Loft conversions in E11 are usually the reason people call, and they are the room most often under-specified. Under a slate roof with a rear dormer, a converted loft needs the size up from what the floor area suggests.
Nearest postcodes we also cover: Tottenham N15, 3.9 miles; Wood Green N22, 5.6 miles; Palmers Green N13, 5.9 miles.

Hackney
Vaillant aroTHERM plus air source heat pump
Fitted in three days as part of a renovation, replacing the gas boiler. It now runs the underfloor heating and the hot water, from a unit on blocks in the side return.

Chingford
Vaillant aroTHERM plus air source heat pump
A smaller unit, sized to what the house actually needs rather than rounded up, fitted in three days during a renovation. It stands on blocks against the house wall.

N15
Tottenham
Air source heat pump with solar and battery storage
The whole electrical side on one wall: inverter, battery modules and every isolator in reach, with the conduit dressed in straight runs so a fault years from now can be traced without stripping the wall.

Heat pump
E1
London
Vaillant aroTHERM plus 7 kW air source heat pump
Built around underfloor heating during a renovation: the old system out and the heat pump running in three days, set on anti-vibration feet on a level base against the fence.

N4
Finsbury Park
Vaillant air source heat pump with solar panels and a battery
The panels on the roof run the heat pump through the day and the battery carries it into the evening, so the house buys far less from the grid. The unit sits on raised feet against the rear wall.

N1
Islington
Vaillant aroTHERM plus 7 kW air source heat pump
There was no room for it in the garden, so it went on the flat roof, stood on rubber blocks over a protective mat so the roof covering carries no point load.

Heat pump
N22
Wood Green
Samsung monobloc air source heat pump
Stood on a levelled base built up out of the border rather than on soil, so the feet stay out of standing water and the unit does not settle out of level over a winter.

Heat pump
N8
Hornsey
Vaillant aroTHERM plus air source heat pump
The owner wanted the indoor equipment out of the living space, so it went into the loft. The outdoor unit has its own base in the garden. Three days, gas boiler out.

See if it paysAir conditioning in Leytonstone: common questions
Am I in the Bushwood conservation area?
Waltham Forest publishes the boundary and it is worth checking before anything else, because inside it a unit visible from the road needs planning permission rather than permitted development.
Behind the building line at the rear, the position is usually straightforward either way. The eight conditions.
Can it go on my kitchen extension roof?
Yes, on a frame that spreads the load. On a Victorian terrace with a built-over side return it is often the best position available.
It also keeps the unit away from the fence line, which is where noise complaints between terraced neighbours start.
Do you cover the rest of Waltham Forest?
Yes. The borough page covers Walthamstow, Leyton, Chingford and Highams Park.
We have installations across E11 and E4.
