The best triple split air conditioners, compared.
Top pick: Generic 989767 3-zone – Highest score at 60, the Generic 989767 3-zone at about £2,049. Best value: Generic 13214556 3-zone – Best value on a different ASIN, the Generic 13214556 3-zone at about £1,949. Updated 20 October 2026.
A triple split air conditioner is a fixed multi-split: one outdoor unit and three indoor heads, each with its own setpoint, usually for three rooms in a UK house or flat. Buyers are homeowners who want cooling and, on a reverse-cycle unit, heating, without three condensers on the wall. Quality is a named outdoor model, a kilowatt rating per room, a GB energy label with SEER, a named refrigerant, and a certified installer, not a marketplace headline of 27,000 BTU. On a standard multi-split the rooms can be different temperatures but not opposite modes at once; heating one room while cooling another needs heat-recovery. In this amazon.co.uk batch only three listings are actually three-zone systems, all unbranded, with no review text in these listings. That suits an owner who wants three rooms on one outdoor unit and can host an installer. A flat leaseholder must clear the freeholder before the condenser, and may fail the 0.6 m³ English volume test.

Question 1 of 2
What do you need it to do?
The Generic 989767 listing is a three-zone mini-split at £2,049.00 on amazon.co.uk, with 9,000 BTU named per zone and 27,000 BTU cooling overall. Heating power is printed as 30,000 BTU, which is the only heating figure among the three listings in this comparison. The page says a new outdoor unit is required, and it names the refrigerant as R410A. Inverter type is listed as no inverter, so the compressor is not sold as a variable-speed unit. The saved listing has no star rating and no review text, and the efficiency line prints SEER 23 rather than a GB energy label. Weight is given as 45.4 kg and the warranty field is empty. It is the top pick in this set because the listing is the most consistent on heating and the outdoor unit, which is a paperwork judgement, not a review verdict.
Pros
Cons
Best for: You want the staged listing that states a heating BTU and a required outdoor unit, and you will still ask for a GB fiche before you pay.
Less suitable: You need an inverter, a named brand, or a kit that already has amazon.co.uk reviews.
Specifications
Common questions
How many zones does the listing state?
Three zones, stated as 9,000 BTU per zone, with 27,000 BTU cooling overall. A new outdoor unit is required.
Does the listing include heating?
Heating power is listed as 30,000 BTU, and the title says heater. The operating-mode field says cooling, and inverter type is no inverter.
What refrigerant is listed?
R410A. The listing also prints SEER 23 and a 5-star BEE rating. It does not print a GB energy-label class.
Generic model 13214556 is listed at £1,949.00 on amazon.co.uk as a three-zone, 27,000 BTU mini-split, with an inverter claimed and a one-year warranty. The voltage field says 220 V and the weight is 100 kg. One line says a new outdoor unit is required and another says an outdoor unit is not required, so the page does not settle whether the condenser is in the carton. Refrigerant is not named, and no heating BTU is given even though the title says heater. The saved listing has no star rating and no review text. SEER is printed as 23 and efficiency as A, which sits on a different scale from a GB label where A+++ starts at a SEER of 8.50. It is the best value in this set on shelf price, if you get the outdoor unit and the gas confirmed before you pay.
Pros
Cons
Best for: A price comparison where you will not pay until the seller confirms the condenser, the refrigerant and a GB product fiche.
Less suitable: You need a listing that already states the outdoor unit and the gas in one consistent way.
Specifications
Common questions
Does the listing include an outdoor unit?
The listing contradicts itself. One line says a new outdoor unit is required. Another says an outdoor unit is not required. Neither line was resolved.
Does it heat as well as cool?
The title says air conditioner and heater. The spec table does not give a heating BTU or kW figure, and the operating-mode field says cooling.
Is an inverter listed?
Yes. Inverter type is listed as has inverter, and the special features name an inverter compressor. No UK energy label is on the listing.
Generic model 434232 is listed at £2,399.00 as a three-zone, 27,000 BTU system with an inverter claimed and R410A named. The power source is printed as solar powered, and cordless is yes, but the page gives no voltage and no panel specification. The listing says a new outdoor unit is required, and that line is consistent. The title says heater and the number of heating elements is 3, yet no heating BTU is given. Noise is printed as 20 dB with no indoor or outdoor split, the same bare figure as the other two listings in this table. The saved listing has no reviews. At the highest price here, leave it if you need a normal corded install on UK mains and the seller cannot document the panels.
Pros
Cons
Best for: You already have a solar design and the seller can document the panels, the inverter and the outdoor unit before you order.
Less suitable: You want a corded fixed system on UK mains with a stated heating output.
Specifications
Common questions

What heating detail is listed?
The title says heater and the number of heating elements is 3. No heating BTU is listed. The operating-mode field says cooling. Refrigerant is R410A.

Zone count. Keep a product only if it is one outdoor system and three indoor units. Single splits, two-zone kits and four-zone kits are different categories. Capacity per room. 9,000 BTU/h is about 2.6 kW.
Zone count. Keep a product only if it is one outdoor system and three indoor units. Single splits, two-zone kits and four-zone kits are different categories. Capacity per room. 9,000 BTU/h is about 2.6 kW. A Daikin 3MXM68A8 example uses three 2.0 kW heads on a 6.8 kW outdoor unit. Ask whether all three ports can run together. Same-mode limit. Each head has its own setpoint. Daikin states that all rooms share one mode: all cooling or all heating. GB energy label.
Mistakes: treating a one-room, two-zone or four-zone listing as a triple split; reading SEER 23 or BEE stars as a UK A+++ label; expecting opposite modes; assuming “pre-gassed” means DIY; ignoring a full consumer unit.
Call a professional for every refrigerant joint, any new circuit, planning or listed-building doubt, and for indoor water, a dead head, or ice on the outdoor coil.

Three typical situations, each with a recommendation from this comparison.
Owner of a house who wants three rooms on one outdoor unit and can host an F-gas installer. You want the staged listing that states a heating BTU and a required outdoor unit, and you will still ask for a GB fiche before you pay.
Flat leaseholder who must clear the freeholder before the condenser, and who may fail the 0.6 m³ English volume test.
Buyer comparing an unbranded amazon.co.uk kit with a named LG or Panasonic supply kit and an installed quote. You already have a solar design and the seller can document the panels, the inverter and the outdoor unit before you order.
The top pick is the Generic 989767 3-zone at about £2,049. It scores 60, the highest in this set. Best value is the Generic 13214556 3-zone at about £1,949, a different ASIN, with score 47. Skip the top pick if the limit in its listing is the job you actually have.
