Air conditioning installation in Kent typically starts from around £1,200 to £1,500 for a single wall-mounted split unit, including the indoor cassette, outdoor condenser, copper pipework, F-Gas compliant refrigerant fill, electrical connection and commissioning. Multi-zone whole-home setups usually run £3,000 to £8,000 depending on the number of indoor heads and pipework length.
Most single-room split-unit installations take between 4 hours and a full working day. Multi-zone systems typically take two to three days. Listed buildings, conservation area properties, or installs that require electrical upgrades or core drilling through cavity walls can extend the timeline. Reputable Kent installers will confirm a time estimate after a free site survey.
Most domestic installs do not need planning permission, but the outdoor condenser must usually be at least 1 metre from a property boundary and cannot face a highway. Listed buildings and conservation area properties often require listed building consent. Always check with your local Kent council, especially in Tunbridge Wells, Canterbury and Sevenoaks, before booking.
Look for F-Gas certification (a legal requirement for handling refrigerants), REFCOM membership, Part P electrical compliance, and product and public liability insurance. REFCOM Elite signals enhanced compliance for refrigerant handling. Manufacturer-specific badges such as Daikin Business Partner or Mitsubishi Pro Partner suggest deeper product training and access to extended warranties.
Daikin, Mitsubishi Electric, Panasonic, Fujitsu, Toshiba and Samsung are the most commonly installed brands across Kent. Daikin and Mitsubishi Electric are generally regarded as premium options for quiet running and energy efficiency, while Panasonic and Toshiba offer strong value. Your installer should match brand and model to your room size, insulation level and intended use.
Yes. Modern reverse-cycle air conditioners (sometimes called air-to-air heat pumps) provide both cooling and heating. They are often more efficient than electric heaters, deliver low-cost shoulder-season heating, and pair well with smart thermostats. Kent installers including All Kent Cooling and JP Air Conditioning routinely fit combined cooling and heating systems for homes and offices.
Each company was scored on six transparent criteria: published starting price, years of trading in Kent, manufacturer partnerships, F-Gas and REFCOM accreditation, geographic coverage across Kent towns, and public review feedback on Google, Trustpilot or Trustindex. Information was cross-checked against each company's own website during May and June 2026. Directory-only listings without independent contact details were excluded.
