Aira's all-inclusive heat pump plan: monthly price, what it covers and the terms

Aira sells heat pumps differently from most installers. Instead of quoting a lump sum for the appliance and the fitting and then leaving servicing and repairs to you, it wraps everything into one subscription-style arrangement: the air source heat pump, the installation, a 15-year guarantee, the maintenance and remote monitoring, all held together in a single monthly plan¹. Which? lists Aira as a clean energy-tech company offering exactly that: an all-inclusive heat pump plan backed by the 15-Year Aira Guarantee².

The plan is free for the first year, after which it moves to its ongoing monthly payment for the rest of the 15-year term¹. Aira also offers flexible finance so the upfront costs can be spread across affordable monthly payments³. The route in is a free home energy assessment, from which Aira builds the installation and the plan around it³.

For a household thinking about energy independence, the plan changes the shape of the decision. It removes the gas boiler and the gas supplier from the equation, but it binds the heating system to one company for a very long term: the guarantee, the servicing, the monitoring and the app all run through Aira. This page sets out what the plan covers, what it excludes, what it costs, and what the small print does.

What the all-inclusive plan is, and what it covers

The all-inclusive plan is Aira's whole-product offer: the heat pump, the installation, the guarantee, the maintenance and the monitoring arrive together, and the householder pays for them as one ongoing arrangement rather than as separate purchases¹. Which?'s Trusted Traders profile describes the same structure, with the system "backed by our 15-Year Aira Guarantee and all-inclusive plan"². The plan begins with a free home energy assessment, moves through what Aira calls seamless installation, and ends at the 15-year guarantee³.

What arrives inside the plan, as Aira lists it:

• the heat pump and its installation¹
• the 15-Year Aira Guarantee¹
• all the maintenance the heat pump needs¹
• remote monitoring and fix¹
• premium app features and heat pump performance reports¹
• 4G connectivity if home Wi-Fi drops out¹

The installations behind the profile show the range of work the plan can absorb. In January 2026 a Derbyshire customer had a 12 kW Aira heat pump plus four replacement radiators fitted in place of a gas boiler; days later another installation involved radiator upgrades, pipework reconfiguration, removal of loft tanks and conversion to direct mains pressure². Those are the kinds of costs that, under a conventional purchase, land on the householder as extras, and under this plan sit inside the monthly figure.

The certification backdrop matters too. The Installation Assurance Authority describes itself as currently the only certification body that mandates an end-to-end consumer protection approach, covering pre-suitability assessments, product suitability, system design, installation quality, consumer protection and aftercare support⁴. That is the standard of scrutiny the industry is moving toward, and a 15-year bundled plan is the sort of product that needs it.

What the plan costs: free first year, then monthly

Aira's product page puts the pricing position simply: "Complete peace of mind. And it's free for the first year."¹ After that first year the plan continues as a monthly payment across the 15-year term. Aira does not publish the ongoing monthly figure on the product page itself, so the number that matters is the one in your own plan documents, quoted after the free home energy assessment¹.

Alongside the plan, Aira offers flexible finance options, so that "you'll have the option to spread the costs across affordable monthly payments"³. That matters because a heat pump installation is a large upfront outlay under the conventional model; the cost of a heat pump is normally paid as a capital sum, and Aira's structure converts it into an ongoing cost instead.

Two things follow from that structure. First, the total paid over 15 years of monthly payments may exceed a one-off purchase price, and the only way to judge that is to compare your quoted monthly figure against an outright quote for the same work. Second, the free first year is a genuine discount on the plan itself, not on the installation, so read which figure the first-year waiver applies to in your paperwork.

The 15-Year Aira Guarantee: the promise and the exclusions

The headline term is the 15-Year Aira Guarantee, which Aira attaches to the heat pump as part of the plan¹. Which?'s profile confirms the same structure: the system is backed by the 15-Year Aira Guarantee and the all-inclusive plan together². Fifteen years is long by the standards of the market, as the table below shows.

The guarantee also carries a performance element. Aira states that the 4X efficiency figure in the Performance Guarantee "is based on an overall heating performance of 340% efficiency for an Aira Heat Pump compared to 85% for a standard gas boiler over the course of a year"¹. Those are the maker's own figures, and the comparison basis is stated by Aira rather than independently measured; the general background to efficiency measures is covered in heat pump efficiency: COP, SCOP and SPF.

The exclusions are specific. The plan "does not cover damage or malfunction caused by e.g. components not supplied by Aira, improper or negligent use, vandalism or violence to the heat pump, or unauthorised tampering with the heat pump"¹. Note the "e.g.": that list is illustrative, not exhaustive, and the plan is limited by Aira's terms and conditions¹. The practical consequence is that any third-party work on the system, or damage from outside, can fall outside the guarantee. As a general rule elsewhere in home energy, faults caused by poor workmanship should be covered free of charge by the installation warranty while it runs⁶, so the boundary between Aira's work and anyone else's is worth keeping clean.

Beyond repairs: maintenance, monitoring, the app and 4G backup

The plan bundles the running of the system, not just its repair. Aira's own line is "All the maintenance your heat pump needs. Included."¹ That covers the routine servicing that a heat pump needs each year, which under a conventional purchase is a separate contract with a separate company. Aira does not publish the visit schedule on the product page; separately, regulations require air conditioning systems to be "inspected by an energy assessor at regular intervals not exceeding five years" for accessible parts of the system⁷, which sets a regulatory backstop for inspection of systems holding refrigerant, though it is not Aira's service schedule.

On top of maintenance, the plan includes remote monitoring and fix, premium app features, and heat pump performance reports¹. The remote monitoring means Aira watches the system from its end and can act before a fault becomes a breakdown; the performance reports give the household visibility of how the system is actually running. The smart-control side of the offer is covered in more detail in Aira Intelligence: the app and smart controls.

One detail is quietly important for reliability: the plan includes "4G connectivity if your Wi-Fi drops out"¹. Remote monitoring depends on a data connection, and a home broadband outage would otherwise blind it. The 4G backup keeps the monitoring alive when the household's own connection fails, which reduces, though it does not remove, the dependence on the home network.

Opting out: the basic 5-Year Product and Installation Warranty

The all-inclusive plan is not compulsory. Aira's own FAQ poses the question of paying for the Aira Guarantee later, asking whether you "can I pay for the Aira Guarantee when my basic 5-Year Product and Installation Warranty runs out?"¹ The wording confirms the structure: a householder who opts out of the all-inclusive plan falls back on a basic 5-Year Product and Installation Warranty, and the 15-year guarantee is the upgrade path from there.

Five years is the floor of the market rather than its ceiling. The ECO4 innovation listings show the competing terms: an Aira ASHP with an extended 10-year parts and labour warranty, and the Ideal Logic Air with a 10-year warranty at no cost to the end-user⁵. Against those, a basic 5-year term is short, which is presumably why the upgrade question exists on Aira's own page.

The trade-off is straightforward. Opting out removes the monthly plan payment and the bundled maintenance, monitoring and app features, and leaves a shorter warranty with servicing to arrange separately. Opting in buys 15 years of cover and everything that runs alongside it, at an ongoing cost. Which suits a given household depends on how much of the running of the system it wants to hand to one company, and for how long.

Instalments and grants: how the cost can be offset

Aira's finance position is that after the free home energy assessment "you'll have the option to spread the costs across affordable monthly payments with our flexible finance options"³. How that interacts with grants depends on the scheme. Under the Boiler Upgrade Scheme guidance for installers, arrangements where the installation is paid for in instalments, alongside unsecured personal loans, can still qualify where the property owner becomes the legal owner⁸; that is the condition that matters for a subscription-style plan, and it is a question to put to Aira in writing before signing.

Beyond the Boiler Upgrade Scheme, the wider funding landscape is expanding:

• The Warm Homes Plan provides fully funded government support to install insulation for people on low incomes⁹.
• It also provides fully funded support to install solar panels for people on low incomes, with low and zero-interest loans for homeowners regardless of income¹⁰.
• The Warm Homes Local Grant is fully funded by the government, so residents who qualify do not pay for the measures covered¹¹.
• Disabled Facilities Grants can be paid in instalments as the work progresses¹².
• Payment plan options for utility bills generally include paying by weekly or monthly instalments or using a pre-payment meter¹³.

The full picture of what is available is in heat pump grants and funding.

The independence angle is worth stating plainly. Grants reduce the capital cost of getting off gas; the plan then converts the remainder into a long-running monthly relationship with one provider. A household that takes both ends up with no gas supplier and no separate servicing contractor, but with a 15-year financial commitment to Aira.

Selling your property: does the plan move with the house?

Aira's own FAQ asks "Can I transfer my Aira all-inclusive plan if I sell my property?"¹, which confirms transfer is a live question for the plan rather than a settled yes. The product page poses the question; the answer sits in the plan's terms, so it is one to nail down in writing before signing, because long-term home energy arrangements behave very differently from one another on sale.

The comparisons make the range clear:

• A Green Deal loan is attached to the property rather than the individual, so if a homeowner sells, the loan passes to the new owner¹⁴.
• A rent-a-roof solar lease can require the householder to get consent during the term if they want to sell or make alterations near the system¹⁵.
• Free solar PV arrangements are supposed to set out arrangements for assigning the arrangement if the property changes hands¹⁶.
• An insurance backed guarantee should include a provision to transfer it to a new owner of the property¹⁷.
• Loan agreements may also let the lender assign rights under the agreement¹⁸.

For a householder, the practical test is which of these patterns the Aira plan follows: does the plan and its payment obligation pass to the buyer like a Green Deal charge, does it end on sale, or does it need Aira's consent to assign? Each has different consequences for a sale, and the only reliable answer is the one in your own contract.

Contract basics: formation and the applicable version

Two pieces of consumer law shape what the plan's paperwork has to do. Under section 50 of the Consumer Rights Act 2015, every contract to supply a service is treated as including "anything that is said or written to the consumer, by or on behalf of the trader, about the trader or the service" if the consumer took it into account when deciding to enter the contract or when making any later decision about the service¹⁹. In plain terms, the claims on Aira's product pages, including the free first year and the bundled inclusions, become part of the contract if you relied on them.

On what a written contract should contain, the Consumer Protection Association guidance is that every contract should include the contractor's registered business name, address and contact details, the full agreed price and payment schedule, warranties and guarantees, complaints and disputes handling, and the right to cancel²⁰. Fairness is assessed under section 62 of the Consumer Rights Act, taking into account the nature of the subject matter of the contract and all the circumstances existing when the term was agreed, together with the other terms it depends on²¹. A 15-year plan with an age deduction clause in its terms is exactly the kind of long contract where those fairness rules bite hardest.

On versions: Aira's all-inclusive plan terms carry version numbers and effective dates, and the version in force when you sign governs your contract. The current terms, version UK-AIP-2.3/2026, took effect on 19 May 2026²². If your plan started earlier, your paperwork may sit under an earlier version, so check the version stated on your own documents rather than assuming the latest published terms apply to you.
