The UK’s best-selling 12,000 BTU smart split — in stock and installable this month.

  • Heats and cools all year: 4-in-1 cool, heat, dehumidify and fan.
  • LG Dual Inverter keeps working hard in extreme weather — and is covered by a 10-year compressor warranty.
  • Control it from anywhere with the LG ThinQ app; set schedules so you never cool an empty house.
  • Active Energy Control caps consumption at 80% / 60% / 40% to keep bills down.
  • A++ rated, so a typical evening’s cooling costs pennies, not pounds.

Sized for rooms up to 24m². Supplied complete with indoor unit, outdoor condenser, wireless remote and full UK warranty. Add F-Gas certified installation from £1650 + VAT at checkout — one team, one invoice, no sub-contractors.
