Guide figures including VAT for typical installations. Long pipe runs, scaffolding, electrical upgrades or difficult access add to the cost.
Price factors
What affects the cost of installing air conditioning?
System capacity (kW)
Bigger rooms, more glazing and south-facing aspects need more cooling power, which means larger, pricier units.
Pipe run length
Standard prices assume a short run. Routing pipework around a house or up several floors adds materials and time.
Wall construction
Solid stone, thick period walls and timber frames need different drilling methods and fixings.
Electrical supply
Most systems need a dedicated circuit from your consumer unit; older boards may need upgrading first.
Outdoor unit position
Ground-level pads are simplest. High brackets, flat roofs or scaffolding add access costs.
Condensate drainage
Where water can’t drain by gravity, a discreet condensate pump is fitted to carry it away.
Our process
The air conditioning installation process, step by step
Free survey
We measure rooms, check the electrics and agree the best positions for indoor and outdoor units.
Fixed written quote
An itemised price with no hidden extras, plus the model, capacity and efficiency ratings.
Installation day
Units mounted, a core hole drilled, pipework, cable and drain connected and neatly finished.
Pressure test & vacuum
The refrigerant circuit is nitrogen pressure-tested and evacuated before the system is charged.
Commission & handover
We test cooling and heating, show you the controls and register the manufacturer’s warranty.
Timescales
How long does air conditioning installation take?
For most homes, less time than people expect:
- Single wall-mounted or floor unit: usually one day, often finished by mid-afternoon.
- Two or three-room multi-split: typically one to two days.
- Ceiling cassettes: one to two days per area, depending on ceiling access.
- Ducted systems: scheduled alongside your builder — first fix during construction, second fix before decorating.
Lead times for equipment are normally short, and we’ll give you a confirmed installation date when you accept your quote.
Planning the layout
Where should indoor and outdoor units go?
Good positioning is the difference between a system that quietly does its job and one that’s noisy, draughty or inefficient.
Indoor units
Wall units work best high on a wall with a clear path for air across the room — not blowing straight onto a bed, desk or sofa. Allow space above for airflow and access for filter cleaning.
Outdoor units
Condensers need free airflow, a firm level base or bracket, and access for servicing. We avoid placing them beneath bedroom windows, next to a neighbour’s patio or in enclosed spaces where hot air recirculates.
Pipe routes
We keep pipe runs short and tidy, using colour-matched trunking outside and, where possible, back-to-back installations so almost nothing shows. Our photos of what to look for in an installer explain why neat pipework matters for performance as well as appearance.
Planning and permissions
Listed buildings, conservation areas and flats can need consent. We flag this at the survey stage so there are no surprises.

Explore floor-mountedHow big is the hole in the wall?
A single core hole of around 65mm diameter per indoor unit, sleeved and sealed after the pipework is fitted.
Do I need to be home on installation day?
Someone needs to let us in at the start and be available at the end for the handover and controls demonstration.
What warranty do I get?
Manufacturer warranties typically run for several years when the system is installed and registered by a qualified installer and serviced annually. We register the warranty for you and explain the terms.
Can you install in winter?
Yes — winter and spring are ideal, as installation diaries are quieter and your system is ready for the first warm spell. It will also heat your rooms in the meantime.
