Aira is a Swedish company that designs its own R290 heat pump, builds it in Wroclaw, Poland, and sells and installs it directly to UK homes. It offers 6, 8 and 12 kW outdoor units, publishes real-world performance data from UK installs, and bundles a 15-year guarantee into a paid all-inclusive plan. As with Octopus Cosy, you cannot buy an Aira unit through an independent installer. We list the 8 kW: Aira does not publish the weight or sound power of the single-phase 12 kW.

Frequently asked questions
How much does a Aira heat pump cost in Scotland?
£14,229 to £19,500 installed before the grant, or £6,729 to £12,000 after a £7,500 grant. These are PumpSwap's indicative 2026 prices; your installer's survey sets the real figure.
Can I get the grant on a Aira heat pump in Scotland?
Yes, if your home qualifies: the Home Energy Scotland grant is not tied to a brand. Apply and get approval before the work starts.
What would a Aira heat pump cost to run in Scotland?
Roughly £640 a year for the Aira 8kW to deliver 10,000 kWh of heat at 26.11p per kWh (Ofgem price cap for Southern Scotland, 1 October to 31 December 2026). That assumes a 45°C design flow temperature, estimated from its MCS-certified SCOPs of 4.62 at 35°C and 3.52 at 55°C. A lower flow temperature, with bigger radiators or underfloor heating, costs less to run.
Who installs Aira heat pumps in Scotland?
MCS-certified installers across Scotland fit Aira. Ask for a heat loss survey and compare two or three quotes on the same basis: unit size, cylinder, radiator changes and warranty.
