Daikin Air Conditioning Review

Daikin is the brand most UK installers name first when asked what they would fit in their own home. Here is our independent look at the range, what it costs installed, and where it makes sense to pay the premium.

An HVAC specialist, not an electronics giant

Unlike most rivals, Daikin makes little else besides heating, cooling and refrigeration — and it shows in the engineering.

Daikin is one of the world's largest dedicated air conditioning manufacturers and was an early pioneer of the R32 refrigerant that is now the industry standard. Its domestic wall-mounted splits sit at the top of the efficiency tables: the best Perfera models reach class-leading seasonal efficiency — SEER up to the ~8.5 mark on smaller capacities — which translates into genuinely low running costs at 2026 electricity prices.

Strengths

  • Efficiency: consistently among the best seasonal figures in each capacity class, in both cooling and heating modes.
  • Quietness: premium indoor units run near-silent on low fan speeds — a real benefit for bedrooms.
  • Build and longevity: installers report low fault rates, and spare parts support in the UK is strong.
  • Design options: Emura and Stylish are among the best-looking wall units on the market if the standard white box puts you off.
  • Installer network: a large pool of Daikin-approved UK installers, which matters more for long-term support than the badge on the box.

Considerations

  • Price: expect to pay several hundred pounds more than a comparable mid-range unit — worthwhile in daily-use rooms, harder to justify for occasional summer cooling.
  • Range complexity: the model line-up is broad and changes regularly; lean on your installer to match the right series to the room rather than fixating on one model name.
  • Premium features cost extra: the design-led Emura and Stylish carry a further premium over the technically similar Perfera.

Who Daikin suits

Daikin is the safe recommendation when the unit will work hard: a home office in daily use, a main bedroom cooled every summer night, or a living space you also plan to heat through winter using the unit's air-to-air heat pump mode. The efficiency premium repays itself fastest with heavy use, and the quietness matters most where you sleep or concentrate. If you want cooling for a couple of heatwave weeks a year, a strong mid-range brand will do the job for less. There is also a 2026 twist for anyone weighing all-electric heating: since 28 April 2026 air-to-air heat pumps — which is exactly what a Daikin wall split is — can qualify for a £2,500 Boiler Upgrade Scheme grant in England and Wales, provided the unit is the home's main heat source with no fossil-fuel boiler retained.

Installer accreditation and warranty

Daikin operates approved-installer schemes in the UK (its D1 network and Sustainable Home Network). Buying through an accredited installer typically unlocks extended warranties — commonly up to 7 years when the system is registered after installation — versus around 3–5 years otherwise. Whoever you choose must be F-Gas certified; that is a legal requirement for anyone handling refrigerant. All engineers we match you with are vetted and F-Gas certified.

Daikin FAQs

For rooms in daily use, usually yes. Daikin's class-leading efficiency lowers running costs, its premium units are exceptionally quiet, and extended warranties of up to 7 years are available via approved installers. For occasional summer-only cooling, a good mid-range brand delivers most of the benefit for several hundred pounds less.
A single wall-mounted Daikin split (2.5–3.5 kW) typically costs £2,000–£3,000 supplied and installed in 2026, depending on the range (Perfera, Emura or Stylish), pipe run length and installation complexity. Multi-room systems start from around £2,800–£5,000 for two rooms.
Yes. Daikin wall splits are air-to-air heat pumps, so they heat efficiently in winter with a typical SCOP of 3.5–4 or better — meaning 3.5–4 kW of heat per kW of electricity. Since 28 April 2026, air-to-air systems like Daikin's wall splits can qualify for a £2,500 Boiler Upgrade Scheme grant in England and Wales, but only where the unit is the home's main heating with no fossil-fuel boiler retained — so a typical summer-cooling install alongside a gas boiler will not qualify.
Typically 3–5 years as standard, extending to as much as 7 years when the system is installed by a Daikin-approved installer and registered after installation. Warranty terms usually require annual servicing, so budget £75–£150 per unit per visit to keep cover valid.
The Perfera is the usual recommendation: it is among the quietest units on low fan speed and highly efficient overnight. Choose the Stylish if wall space is tight or looks matter, and the Emura if you want the flagship design. Your installer will size the capacity to the room.
It can, under the 2026 rules. From 28 April 2026 the Boiler Upgrade Scheme was extended to air-to-air heat pumps, and a Daikin wall-mounted split is an air-to-air heat pump — so it can attract a £2,500 grant in England and Wales. The condition is that the unit must provide the property's main heating with no fossil-fuel boiler kept as backup, and air-to-air systems don't produce hot water. That means most people fitting Daikin for summer cooling alongside a gas boiler won't qualify, but households going all-electric for heating may. Your installer applies for the grant on your behalf and can confirm eligibility at survey.
