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

Aira sells a heat pump with a service plan attached, and the plan is the part that makes the offer unusual. The published price is £19.90 a month for 15 years, and Aira states the plan is free for the first year¹. In exchange, the household gets a 15-Year Aira Guarantee, all the maintenance the heat pump needs, remote monitoring and fixes, premium app features and 4G connectivity if the home wi-fi drops out¹.

The plan is optional. A household that declines it keeps a basic 5-Year Product and Installation Warranty instead, and Aira's own material asks whether a customer can pay for the Aira Guarantee later, when that shorter warranty runs out¹. So the choice is not between a guarantee and no guarantee, but between a long one paid monthly and a shorter one included.

What the plan does for energy independence is narrow and specific. It keeps the heat pump working and monitored without the household arranging its own servicing, and it removes the gas boiler and the gas supply from the house. What it does not remove is dependence on a company: the guarantee, the monitoring, the app and the 4G backup all run through Aira, and the monthly payment runs for 15 years.

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

The plan bundles a heat pump installation with a long guarantee and a service arrangement. Aira describes it as complete peace of mind, free for the first year, and lists what sits inside it: the 15-Year Aira Guarantee, all the maintenance the heat pump needs, remote monitoring and fix, premium app features, heat pump performance reports and 4G connectivity if the home wi-fi drops out¹. The company's own profile describes it as an all-inclusive heat pump plan with a 15-Year Aira Guarantee².

The route in starts with a free home energy assessment, which Aira describes as running from that assessment through to installation and the 15-year guarantee³. That assessment is where the heat pump is sized and where any radiator or pipework changes are identified. Aira's own installation records show what that can involve in practice: a 12 kW heat pump with four replacement radiators in a Derbyshire home, and a separate job involving radiator upgrades, pipework reconfiguration, removal of loft tanks and conversion to direct mains pressure².

For a household, the plan's value is that it converts a set of separate obligations, servicing, monitoring, repairs, into one monthly figure and one point of contact. The trade-off is duration. Fifteen years is longer than many households stay in a property, and longer than the period over which a household can be confident about any company's circumstances.

The wider certification picture is worth knowing. The Installation Assurance Authority states it is 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 describes a standard a scheme can be measured against, not a statement about any particular company.

Price: £19.90 a month for 15 years, with the first year free

The headline is simple. Aira states the plan is free for the first year, and the published monthly figure is £19.90 across a 15-year term¹. The first year being free does not shorten the guarantee: the 15-Year Aira Guarantee is the term being paid for, and the free year sits at the front of it.

Read as a total, £19.90 a month over 15 years is a long commitment, and it is a commitment to a company as much as to a machine. The plan is not a warranty that comes with the hardware and stays with it regardless; it is a service contract with a monthly payment and a term.

There is no published Aira list price for the heat pump itself in the material available here, so the cost of the installation is quoted rather than listed. Aira states that households have the option to spread the costs across affordable monthly payments with flexible finance options³. That is separate from the £19.90 plan charge, and the two should not be confused: one is the cost of the equipment and its fitting, the other is the cost of the guarantee and service arrangement that follows.

The 15-Year Aira Guarantee: what it promises and what it excludes

The guarantee is the centre of the offer. Aira calls it the 15-Year Aira Guarantee and pairs it with the all-inclusive plan¹. An independent business profile describes the arrangement the same way, stating that the system is backed by the 15-Year Aira Guarantee and all-inclusive plan².

Its performance promise is expressed as efficiency, not temperature. Aira states that the four times efficiency figure in the Performance Guarantee is based on an overall heating performance of 340% efficiency for an Aira heat pump compared with 85% for a standard gas boiler over the course of a year¹. That is an annual modelled comparison between two technologies, and it is the maker's own figure. It is not a commitment that any room reaches a particular temperature on any particular day, and it is not an independently verified seasonal performance figure for a specific house.

The exclusions are set out plainly. Aira states the plan is limited by its terms and conditions and does not cover damage or malfunction caused by components not supplied by Aira, improper or negligent use, vandalism or violence to the heat pump, or unauthorised tampering with the heat pump¹. Those four categories cover most of the ways a heat pump can be damaged by something other than fair wear.

There is also a warranty age deduction clause in the plan terms, which Aira's own questions and answers raise directly, offering an example of how it works¹. A deduction clause reduces what a guarantee pays as equipment ages. The percentages and the worked example sit in the terms themselves, and the version that applies is the one supplied with the contract.

What's included beyond repairs: maintenance, monitoring, app and 4G backup

The plan is broader than a repair promise. Aira lists all the maintenance the heat pump needs as included, alongside remote monitoring and fix, premium app features, heat pump performance reports and 4G connectivity if the home wi-fi drops out¹.

The 4G backup is the detail that matters most for how the system behaves when the broadband fails. Remote monitoring and remote fixes depend on the heat pump being reachable over a network. A 4G connection provides a second route when the home wi-fi is down, which keeps monitoring and remote diagnosis working. It does not make the heat pump dependent on the mobile network to heat the house; it keeps the monitoring layer connected.

The app features and performance reports are the visible part of the same arrangement. A household can see how the system is running, and Aira can see it too. That is the trade: better visibility and faster diagnosis in exchange for the manufacturer holding a live connection to the equipment.

On servicing frequency, the published material states that maintenance is included but does not set a fixed number of annual visits. For context on how inspection intervals are handled in law elsewhere, air conditioning systems are required to be inspected by an energy assessor at regular intervals not exceeding five years for accessible parts of the system⁵. That is a statutory minimum for a different category of equipment, not a service schedule for a heat pump, and it should not be read as one.

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

The plan is not compulsory. A household that declines it keeps a basic 5-Year Product and Installation Warranty, and Aira's own material asks whether a customer can pay for the Aira Guarantee when that basic warranty runs out¹. So the shorter warranty is the default, and the plan is the upgrade.

Five years is a common length for a heat pump warranty in the UK market. For comparison, an extended 10-year parts and labour warranty appears in official scheme documentation for an Aira air source heat pump, and a 10-year warranty at no cost to the end user appears for an Ideal Logic Air unit across four model sizes⁶. Those figures show what sits at the longer end of the market, and they are recorded in scheme documents rather than in a sales page.

The practical difference between the two Aira routes is what happens in years six to fifteen. Under the plan, the guarantee and the maintenance continue. Under the basic warranty, cover ends at five years unless the household buys the plan later, which Aira's own question implies is possible¹.

For a household weighing independence, this is the clearest structural point on the page. The longer protection is not attached to the machine; it is attached to a continuing payment and a continuing relationship with the company that installed it. A household that wants the 15-year term is choosing a 15-year commercial relationship, and should read it as one.

Paying in instalments and how government grants offset the cost

The installation cost and the plan cost can be handled differently. Aira states that households have the option to spread the costs across affordable monthly payments with flexible finance options³. That is the maker's own description of its finance route, and the terms of any credit agreement are separate from the plan.

Public funding works alongside private finance rather than replacing it. The Warm Homes Plan is described as including fully funded government support to install insulation for people on low incomes⁷, and separately as fully funded government support to install solar panels for people on low incomes, with low and zero-interest loans for homeowners regardless of income⁸. The Warm Homes Local Grant is described as fully funded by the government, so residents who qualify do not have to pay for the measures covered⁹.

Independent analysis of retrofit support describes a package combining fully funded upgrades for low income homeowners in inefficient homes, grants tapered by household income, and government-backed low interest loans¹⁰. Older schemes show the range of models that have been used: the Green Homes Grant covered up to 65% of the total cost for able-to-pay homeowners¹¹, while its low-income arm was intended to cover the full cost of the improvements installed¹².

Payment arrangements themselves vary. Disabled Facilities Grants are paid in instalments as the work progresses¹³, and for utility bills the options include paying by weekly or monthly instalments or using a pre-payment meter¹⁴. Those are different contexts, but they show that staged payment is a normal structure in UK domestic funding.

Selling your property: can the plan transfer with the home?

Aira's own questions and answers include the question of whether the all-inclusive plan can be transferred if the property is sold¹. That the question is asked on the maker's page is the fact available here; the answer sits in the plan terms.

The wider UK pattern for arrangements tied to a property is that they often run with the building rather than the person. A Green Deal loan is attached to a property rather than an individual, so if a homeowner sells, the loan passes to the new owner¹⁵. Insurance backed guarantees commonly include a provision to transfer the guarantee to a new owner of the property¹⁶. Free solar panel arrangements include stated arrangements for assigning the arrangement if the property changes hands¹⁷.

Other arrangements work the other way. Registered exemptions under the private rented sector minimum energy efficiency standard do not transfer with the property and cease to apply once it is sold, though the energy performance certificate can transfer¹⁸. A rent-a-roof solar contract analysed by Which? stipulated that the householder would have to get consent during the term of the lease if they wanted to sell the house, or make alterations near the system¹⁹.

For a 15-year plan, this matters more than it would for a five-year warranty. A household that expects to move within the term needs to know, before signing, whether the remaining payments and the guarantee move to the buyer, whether the seller keeps paying, or whether the plan ends on sale. That answer is in the terms version supplied with the contract, not in the marketing page.

The terms: how the contract is formed and which version applies

The Aira All-Inclusive Plan terms version UK-AIP-2.3/2026 took effect from 19 May 2026¹. A contract is formed on the terms in force when it is agreed, so the version number and date on the document that comes with the quote are what govern the arrangement.

Consumer law adds a layer that households often do not expect. Every contract to supply a service is treated as including as a term anything 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 a decision about the service afterwards²⁰. In plain terms, a statement made during the sales process can become part of the contract.

Fairness is judged in context. A contract term is assessed taking into account the nature of the subject matter of the contract, all the circumstances existing when the term was agreed, and all the other terms of the contract or of any other contract on which it depends²¹. That is why the whole document matters rather than one clause read alone.

Independent guidance on what a written contract should contain lists 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 cancel²². For heat networks, official guidance goes further: a relevant supply contract must be in writing, drafted in plain and intelligible language, set out in a single pack that does not incorporate terms by reference to any website, and include all terms and conditions for the supply. That standard applies to heat networks rather than to an individual heat pump contract, but it shows the direction of travel in consumer protection for domestic heating.

For energy supply contracts, the licence condition requires the licensee to ensure the terms and conditions of each relevant contract comply with and reflect the condition, and not to enforce incompatible terms²³. Again, that is a different market, and it illustrates the principle that terms are not simply whatever a company writes.
