Four steps from first call to cool air.
Most projects complete inside a fortnight. You'll have the same project contact from first call to commissioning.
Free site survey
An engineer visits, measures heat load, checks pipe routes and agrees where the outdoor unit sits. Around 45 minutes, and it costs you nothing.
Fixed written quote
Two or three options with equipment named, running costs estimated and everything itemised. Valid 90 days, no hidden extras.
Installation
A two-person team, protected floors and a tidy finish. One room is usually a day; a multi-split two to three.
Commissioning & handover
Pressure test, vacuum, F-Gas paperwork, app setup and a walkthrough of the controls before we leave.
Surveys are free, and there's no obligation to proceed. Weekend and evening appointments available.

Do I need planning permission for air conditioning? +
For most houses in England the outdoor unit falls under permitted development, provided it is below 0.6m³, not on a wall facing a highway and sited away from the boundary. Flats, listed buildings and conservation areas usually do need consent — we'll tell you at the survey and can prepare the drawings if needed.
How much does it cost to run? +
A 3.5kW unit cooling a bedroom draws roughly 0.6–0.9kW once the room is down to temperature — around 20p an hour at current UK electricity prices. In heating mode the same unit delivers about 3.5–4kW of heat for every 1kW of electricity, which typically undercuts a gas boiler per kWh of useful heat.
How noisy are the units? +
Indoor units from Daikin and Mitsubishi Electric run from 19–22dB on low — quieter than a library. Outdoor units sit around 45dB at one metre; we position them with your neighbours in mind and use anti-vibration mounts as standard.
Will it heat my home in winter? +
Yes. Every system we install is a reversible air-to-air heat pump, rated to produce full heat output down to around −15°C outdoor temperature. Many customers use theirs as their primary heat source in spring and autumn.
How disruptive is the installation? +
A single-room install is one day: one core drilled through the external wall, pipework run in trunking or concealed where possible, floors covered throughout. Multi-room systems take two to three days. We make good around all penetrations before we leave.
What servicing does it need? +
One annual service keeps the manufacturer warranty valid: filter clean, coil check, condensate flush and a performance test. Our domestic plan starts at £95 a year and includes priority callout.
Which areas do you cover? +
London and surrounding areas. Commercial projects considered nationwide — call the office to discuss.
