Aira's heat pump subscription is a fixed monthly fee covering installation
The Aira heat pump subscription model charges a monthly fee (typically £25–£50 depending on property size) that includes the heat pump unit, installation, ongoing servicing, and any repairs for the contract term (usually 10–15 years). Unlike buying outright, there is no upfront capital cost; the homeowner pays a single monthly payment. The subscription does not cover electricity costs to run the heat pump, those are billed separately by the household’s energy supplier (DESNZ, 2026).
A typical Aira heat pump subscription costs between £25 and £50 per month for a standard 3-bedroom home
Monthly subscription fees are quoted by Aira based on property size and heat loss; for a 3-bedroom semi-detached house, the figure is approximately £30–£40 per month in 2026 pricing. The subscription is fixed for the contract term, so increases in the Retail Price Index (RPI) or other inflation metrics are not applied annually, Aira guarantees no price rises during the term (Aira UK pricing page, 2026). This fixed-rate structure differs from energy tariffs, which can fluctuate annually under Ofgem’s price cap.
The subscription covers installation
Installation includes the heat pump unit, indoor cylinder (if needed), pipework, and commissioning, all covered by the monthly fee. Annual servicing is mandatory and included; Aira schedules and pays for the visit. Any component failure or repair during the contract term is covered with no additional charge to the homeowner (Aira subscription terms and conditions, 2026). This contrasts with outright ownership, where a single compressor failure can cost £1,000–£2,000 to replace outside warranty.

Aira subscription eligibility requires a suitable property and an MCS-certified installer
The property must have adequate space for an outdoor unit and an indoor cylinder (typically 1–2 square metres indoors, 1 square metre outdoors). A heat loss survey is required before approval; homes with poor insulation (e.g., no cavity wall or loft insulation) may be rejected or require upgrades. Aira uses MCS-certified installers for all subscription installations; the homeowner can verify the installer on the MCS register (MCS register, 2026). TrustMark also provides additional quality assurance for all work carried out under the scheme (TrustMark, 2026). compare heat pump subscription eligibility criteria
The Aira heat pump subscription reduces your heating bills by 20–40% compared to a gas boiler
Running costs for a heat pump are typically 3–4 times more efficient than a gas boiler (a Seasonal Coefficient of Performance of 3–4 means 1 kWh of electricity produces 3–4 kWh of heat). For a 3-bedroom home using 12,000 kWh of gas per year (gas price 6.5p/kWh in 2026), the gas heating cost is £780; an Aira heat pump (electricity price 24p/kWh, SCOP 3.5) costs £822, but this is before the electricity price cap or time-of-use tariffs (e.g., Economy 7) can reduce it further. Estimated bill reduction: 20–40% if replacing an old gas boiler (G-rated, 60% efficient) or electric storage heaters; 10–20% if replacing a modern condensing boiler (90% efficient) (Energy Saving Trust, 2026; Ofgem energy price cap, April 2026).
You can cancel the Aira subscription early, but you pay a penalty
Early termination fees are calculated based on the remaining months of the contract term (e.g., 50% of remaining monthly fees if cancelled after 5 years). If you sell the property, the new owner can take over the subscription (subject to Aira approval) or you pay the early exit fee (Aira subscription contract terms, 2026). This compares with other heat pump subscription providers such as Octopus Energy and E.ON, which typically charge similar exit penalties but may offer shorter 5-year terms.
Aira’s heat pump subscription is eligible for the Boiler Upgrade Scheme grant of £7,500
The Boiler Upgrade Scheme (BUS) provides a £7,500 grant for air source heat pumps in England and Wales, applied directly to the installer (Aira), the homeowner does not handle the grant. For subscription customers, Aira deducts the grant from the overall system cost, reducing the monthly fee (Aira quotes the fee after grant deduction). The BUS is available until 2028 (confirmed by DESNZ in 2026); eligibility requires the property to have a valid EPC with no outstanding recommendations for insulation (GOV.UK Boiler Upgrade Scheme, 2026). check if your home qualifies for the Boiler Upgrade Scheme
