Air Conditioning Installation

A single-room air conditioning installation starts at £1,650 fully fitted, a lounge-sized split is typically £2,149, and a two-room multi-split around £3,490. Every price includes equipment, labour, F-Gas commissioning and VAT, and is fixed in writing after a free survey.

Most single-split installations are completed in one day. A two- or three-room multi-split usually takes two to three days, and commercial VRF projects are phased around your opening hours. We confirm the timeline at survey stage.

Most domestic installations fall under permitted development in England, provided the outdoor unit is not on a wall facing a highway, is below 0.6 m³ and is sited away from boundaries. Listed buildings and conservation areas usually do need consent — we check this before quoting.

Yes. Every engineer is F-Gas certified and we are REFCOM registered, which is a legal requirement for anyone handling refrigerant in the UK. You receive full commissioning paperwork and F-Gas records on completion.

Yes. Every system we install is a reverse-cycle heat pump, so it cools in summer and heats efficiently in winter — typically delivering 3 to 4 kW of heat per 1 kW of electricity used.

All installations carry a 5-year parts and labour warranty, backed by the manufacturer's own warranty on equipment, provided the system is serviced annually.

We install across London, Surrey, Kent, Sussex, Essex, Berkshire, Hertfordshire and Buckinghamshire, with engineers based in Reigate covering the surrounding towns daily.

A typical UK bedroom up to about 25 m² usually needs a 2.0kW to 2.5kW unit, while larger lounges often need 3.5kW to 5kW. Window area, insulation, occupancy and heat-producing equipment can change the result, so we complete a heat-load survey before specifying equipment.

You can complete limited preparation work, but connecting or commissioning a split system containing regulated refrigerant must be carried out by an appropriately certified F-Gas engineer. Professional installation also protects the equipment warranty and confirms the system is pressure-tested and leak-free.

We protect floors and furniture, core-drill a single 65 mm hole per indoor unit, mount the indoor bracket, run insulated copper pipework, condensate drain and cable, then site the outdoor condenser on anti-vibration mounts. The system is nitrogen pressure-tested, evacuated below 500 microns, charged by weight and commissioned in both cooling and heating before handover.

Yes. A fixed system needs a dedicated circuit from the consumer unit with an isolator local to the outdoor unit, installed and certified under Part P of the building regulations. We include the circuit and issue the electrical certificate in your handover pack, provided the consumer unit has spare capacity.

Any system with an effective rated output above 12 kW must be TM44 inspected at least every five years and the report lodged on the national register. That covers most offices, retail units and larger commercial installations; typical single-room domestic systems are below the threshold.

Modern inverter indoor units run at roughly 19–24 dB(A) on low fan speed, quieter than a domestic fridge, and outdoor condensers around 45–49 dB(A) at one metre. Correct siting away from bedroom windows and party walls, plus anti-vibration mounts, keeps noise within MCS 020 permitted development limits.
