Aira

Recently contacted Aira with a minor heat pump issue. I phoned the team Monday morning 9am, by midday I had an engineer at my house solving the problem. Very friendly customer service, extremely quick to send out an engineer, and Alfred (the engineer) was very quick to locate and solve the problem. Very happy customer.

The full process from initial enquiry through to install and completion was excellent. The quote wasn’t the cheapest I received, but I was sold on the level of service, the quality of the product, and the warranty that came with it. The install was a bigger job than some as the house required a complete re-pipe. The team kept the house as clean as possible, putting floorboards and carpets back at the end of each day. The majority of radiators were replaced, and the finished install is neat and tidy. Since the install we’ve had a house that stays at a constant temperature no matter how cold it gets outside. We’ve also never once run out of hot water. The app to manage and control the system is very user-friendly. The system itself makes very little noise — I actually think it’s quieter than the gas boiler was. The install was completed in July 2024, meaning we’ve now had it for two winters. Bills have been slightly cheaper than with the previous gas combination boiler, but the biggest difference is how much more comfortable the house now feels. My experience with Aira from start to finish has been fantastic.

The best bit is the 15 year maintenace guarantee. This wasn't my initial top priority. I was just looking for low initial cost but am very glad that I ended up with Aira. There have been some issues but the way these have been dealt with in my case has been exemplary. Many issues can be sorted remotely (Thank God for the internet!) but on a Sunday when this was not possible an engineer drove immediately some 30 odd miles to fix the issue. Couldn't be better. This is not a "top of the range" service as the price is "competitive" so they don't do cosmetic re-instatement. If you need that then you have to factor in the extra cost. On the other hand when they found deficiencies in our existing infrastructre they upgraded it without asking for extra money. (Anticipating this was what swung my decision to choose Aira. Their quotation had no caveats in this area.) Small details: The neutral (muddy?) colour of the outdoor unit I prefer to the stark white of other units on the market. On the other hand the fan is not as quiet as some are ... but unless you live more than a half mile from the nearest road, or waterfall it's not going to be a problem.

We had a heat pump installed to replace an old Baxi back boiler installation in a standard terraced house (normal cavity wall insulation, loft installation and double glazing). The installation involved changing most radiators in the house and adding some new ones, a couple of these were not straightforward, and I was impressed with communication at the visit and planning stage, with different options considered and changes made to the installation as a result of my feedback. The trickiest part was probably some of the preparation needed by me prior to the installation, including installing a loft platform for the tank, but ultimately this was all fine. The removal and installation itself went smoothly. The communication throughout on progress/ queries from a friendly team was good (despite the team clearly being pushed for time). My only slight issue was I was told there was a component replacement needed that was promised to be fixed by a repeat visit by the electrician, this never happened but when I chased Aira I was assured there was actually not a problem. Since the system is working absolutely fine this seems to be true, and if there's any minor issue I hope it will be fixed at service. Carbon saving was our main motivation but due to the age of the previous installation I was hoping we'd also save money on bills and I'm now confident this is the case. Otherwise the system looks good, is very quiet, the Aira app is great, and the constant temperature is a real benefit.

Installation took 4 days, the team(Lloyd & Chris) worked on our existing pipe work, changing all radiators to new specifications for the system. They were professional and friendly at all times, keeping us updated on the progress of the install. System came online Thursday and before the team left the house was warming up nicely. Since then, we've been impressed with how warm the house has been in cold weather and how well the hot water system works in the summer and the winter. One of the unexpected benefits of the system is we no longer get condensation on the inside of our windows. The thermostat works well within the house but you do have to have it in the correct position. We have ours in the middle of the house away from any radiators. The heat pump is extremely quiet when operating. It's no louder than a domestic fan. Cool down settings for night operations(10pm -3am) reduces temperature by 1 to 2 degrees centigrade is best for comfortable sleeping and efficiency. The house is never cold being set between 22 and 23° c. In the summer months the system adjusts to only heating the water as heating is not required. We monitor the system through an app but the system is self managing. We have had no issues with installation & our first year living with our Aira heat pump. We would never go back to a gas boiler and would recommend Aira as first choice with the 15 year comfort and maintenance guarantee.

Great installation, price and equipment. Our heating bills have reduced. At the time Aira's deal for purchase and maintenance was the best on the market (and may still be). However the software is still evolving and every release has issues. Aira won't share their optimisation algorithm. My opinion is that this is still immature. They have listened to feedback on other areas and made changes. Overall very happy with the purchase but expecting more bumps over the next few years as the software catches up with the hardware and sales. Maintence is also an unkown.

Aira fitted our new Heat Pump in July 2025. We also had piped underfloor heating installed downstairs at the same time but this was done by another trades person. The installation went very well and the team were very professional clean and tidy. There's a lot involved in retrofitting a heat pump into a 1990s house. There are many things to consider and some unexpected differences to our old gas boiler set up. Intially we found that the downstairs with the underfloor heating was getting much warmer than the upstairs with radiators. But an Aira engineer came out and spent a whole day checking everything and making the necessary adjustments. Since then we seem to have gone through our first winter with a nice warm home. 21 degrees all day long. I must admit I'm still trying to get the optimal setting to suit out house and our energy tariff, but like the whole energy transition thing, it's just a matter of experimenting and noting what works best. I've not noticed a huge difference in my energy bills, but again that's difficult to do a straight comparison as we now have an electric car, solar panels and house battery as well. I do know that the solar and battery set up saved us around £1000 in the first year and electric car another £1000. I've certainly not noticed any increase in my bills due to the heat pump. So far very pleased with the Aira heat pump.

This was new for us and as Aira UK was new to this field it was new to them but it went well. A few problems afterwards and breakdowns but they resolved it well and timely. We have a great system which works for us but … you do need good insulation for this to work for you

Brilliant work the heat pump is more efficient and keeps the house warm all day. It is strange as the radiators are not red hot but give a nice constant heat Water is set on the lowest temprsture and is still red hot all day.

Aira wanted to complete our installation within 5 days. They started on a Tuesday (after a bank holiday) and needed this Saturday to complete. Fortunately, the senior installers were able to accommodate staying late on that Saturday to get the job done. Prior to error being on site, I had arranged for some new pipework to be installed which will have saved Aira both time and money. However, Aira did not acknowledge this gesture. During the installation a small amount of damage to our property was encouraged, particularly wooden floors because the storage unit is so large I'm difficult to move in the confines of the house. We are fortunate to have sufficient loft space that the 100 litre secondary tank was able to be fitted without interfering with space at in all living areas. The installation has worked well over the last year after initial teething problems. Our house now remains at a constant 20° which we find very comfortable. We did try to set a lower temperature at night but were never able to achieve it because the system ignored the command! The hot water has also worked well. The system does require pumped water between the external heat exchange unit and the secondary tank and of course between the storage unit and all the house radiators. We are aware of an amount of water coursing noise in the house because of these two systems. This can be a little disconcerting. We have not needed to call upon Aira to revisit the installation over the last year.

We live in an 125yr old cottage with a 30yr old granny annex and always believed ASHP was for modern well-insulated houses. We had the survey done and the Aira technicians did a very thorough survey and built a virtual model of our house and ran it for a week or so to test that it reached and maintained the desired temperature. (19.5C in house & 21.5C in the annex). Although our house is old with all solid walls we do have modern double glazing and quite good celotex roof insulation. Because of the guarantee of the required temperatures and the fact that all the equipment was Aira’s and that they didn’t use subcontractors we decided to go ahead. The whole experience was great. From initial enquiry to final commissioning everyone of the Aira staff couldn’t do enough to please. We got a well-designed, well-installed split system with 2 thermostats and 5 upgraded radiators out of 15. Nothing was rushed and everything was clean & tidy. We have just lived through our first winter with the system running 24/7. Yes we have used more electricity but no where near the cost of £1300 we were spending on heating oil and boiler servicing. Yes we have got solar panels and a battery, but we believe even without this there would still be a saving. We won’t know until a year has passed how much we have saved, but it’s looking substantial. The other major plus especially for my elderly mother is that the house & annex is always warm & we have loads of hot water. We’re very pleased with Aira

We moved into a bungalow which had a gas boiler that was 14 years old. We decided that rather than wait for it to fail we would research the market. Having done much reading we set about sorting insulation measures prior to having an air source heat pump installed. The property was listed with an EPC of E so we had cavity wall insulation and hubby set about the loft which was poorly insulated. We chose Aira as we thought they would have a lot of experience (60pc of homes back in their country were on heat pumps). The installation was easier than we were expecting. We had to have 2 extra radiators added and 3 of the existing ones upgraded. There was hardly any mess and I can honestly say we have never been warmer. We were able to take advantage of the government grant and this was all taken care of by Aira with no hassle for us. This made a big difference to overall cost..... And we have gone green saving tons of CO2 going into the atmosphere.

We had a 8kW Outdoor Unit, 250litre Indoor Unit, 40ltr buffer and all pipework and electrics, plus 12 Radiators as part of our new Air Source Heat Pump system. We also had Solar Panels and Batteries installed by the Sister Company (All Seasons) From Quote to Install the whole process was smooth, efficient and simple and we were kept informed throughout They even allowed us to purchase a Designer Radiator for our Kitchen because it was on show and their standard one was not suitable cosmetically in our opinion. They were very helpful in advising what criteria the radiator needed to meet, and were more than happy to fit it as part of the job The installation Team(2Plumbers&1 Electrician)were extremely pleasant and friendly and very considerate of our Residence. They took 4 days in total, driving down to the Midlands from North West on Day1 and then staying in a Local Hotel until the job was finished. They started early in the morning about 8 am and worked continuously until 5-6pm with a brief lunch break. They were a joy to have work for us. It has been a year since system installed and we are extremely happy. House has been warm during the wet cold winter. Hot water readily available. Quiet outdoor Unit. Aira App allows adjusting settings and viewing of output as well as Holiday settings when heating/water not needed. It has been a lot cheaper than old Oil Central Heating System(though mainly due to Solar, which strongly recommend) A minor issue after install was fixed rapidly

I was so pleased to have been recommended AIRA!. I had started the process of having a heat pump installed by 2 other companies which I did not follow through. The process of design, consultation, visits from AIRA were so professional and any queries I had were followed up by a dedicated team. When the work was carried out the team were considerate and tidy. ( Some home baking seemed to help the energy levels) I have been left with a warm cosy home which I am delighted with. I make use of the app to make optimal adjustments. I felt that a company that offered 15 year guarantee was good and its connection with a Nordic country that use heat pumps as their main source of heating must have the expertise needed. The pump works alongside my solar panels.

Didn’t pay too much attention to the sales meeting. It was a usual meeting with a sales person. Tech survey was good. There was a glitch at the design stage - the initially proposed design simply wouldn’t fit into the dedicated space. I’m not sure if it was an issue in tech survey or a miss on the design stage. When I saw the design I clarified all dimensions for the equipment it became obvious it would be impossible to fit. But the issue was quickly fixed - the design team suggested an amended design that was feasible. Installation went smoothly, the team was attentive to the pipes allocation to make the outside part of the installation better looking and less disruptive. The whole setup including an all-in-one unit and 100l buffer was fit into a custom kitchen unit. System performance is above expectations, it’s Ben performing better than the previous boiler based system (that was 2yo) even at a higher setpoint temperature at the highest comfort level. A bit disappointing the system doesn’t provide any means to monitor its consumption for smart home systems, it would make the system even better. In tandem with a battery the system worked cheaper than gas every single month of the heating period

I was a bit concerned about having a heat pumpdue to a previous experience but after some research I contacted Aira. They could not have been better. Fully explained the system to me in terms I could understand and detailed what would be my experience of the install. They two installers were most respectful of my home and worked for two days arriving when they said they would and leaving the place clean and tidy when they left. Before finally leaving they explained the system again and took me though the app in order that I had full control. During this year I have had two very minor problems and the response was very quick in fact they attended the next day and fixed the issue. Firstly I would highly recommend a heat pump to anyone considering it. We have saved over £100 per month to date. Secondly I would highly recommend Aira not only for their exceptional product but for the service at every stage.

When we were considering installing a heat pump we spent much time researching the market, bot on the equipment side and looking at installers. Heat pump installation and controls are critical. Incorrect installation can be very costly throughout the life of the heat pump. My control engineering background helped with both aspects: I was able to assess the equipment and also make sure that the installers knew what they were talking about during the initial visits and in their quotes. We had five visits and four quotes, and this is my advice to anyone planning to have a heat-pump installed. Keep asking questions, get several quotes. Aira stood out in terms of the T&Cs as well as my perceived know-how of their designers. And we are not disappointed. A year and four months later we are still enjoying an efficient heating system, its set-and-forget well-designed controls, and above all a warm and healthy house with no on-off of high heat gas powered heating, no fluctuating temperatures, no cold spots. The installation did not involve lifting the floorboards, just replacing the radiators, adding some, and of course removing the old gas boiler and installing the new HW tank and the "machinery". The installers spent a working week with us - the experience was excellent. In spite of a relative (controllable) upheaval they have shown care and respect, and high professional skills. Customer support was responsive and effective. I highly recommend Aira.

A 4 - day installation of 8 radiators and heat pump. All carried out with care by an experienced team. As soon as the system started up we could feel the warmth spreading throughout the house. Places that had never been warm with the old gas boiler were suddenly comfortable to sit in. It was like those adverts you see with snow on the ground outside whilst people are sitting on the warm on the other side of the window! Monthly bills dropped from £177 to £120. Also no need to keep the gas boiler maintenance insurance. The number pipes and tanks that are required to support the pump were a bit of a shock, but with care by the installers they were all fitted into existing cupboards and our utility.

Aira quoted me a price and there was no extras the installers were excellent at their job and there was no mess left at the end of etch day they were working here. the heat the heat pump does exactly what they told me it would do,it’s still early days but I am othe opinion that it will be more efficient and economical than my old gas boiler was. Regards

We took the leap to move away from our oil fired heating and hot water setup and have an ASHP. After looking around and listening to several companies offerings we chose AIRA. Our house is over 200 years old, but we do have recent double glazing and an insulated loft. The whole process was mapped out after several surveys (during which the size of ASHP required was reduced), and we had an installation date set for the begining of June 2025. On the first day of installation the team arrived, along with a lot of kit to be installed, and they immediately started the work. It took 3 and a half days to install the kit (and upgrade 4 radiators) and the team were extremely efficient, cleaned up as they went, and explained what they were doing as they went along. On the first day the installation team identied a flaw in the system design that required an extra pump to be installed, and this was supplied and fitted at no cost to us, as the issue was with the AIRA design. Once completed we were walked through how to control the system with the App, and all rubbish (and there was a lot) was removed by AIRA, so everything was left clean and tidy. We have only had one issue which was when an App upgrade caused the hot water function to be turned off, but this was rectified within an hour or so. I would use AIRA again in the future without hesitation, and willingly recommend them to family and friends.

Almost everything was excellent, and I am now, after my first winter, very happy to be a heat pump owner. The system definitely uses less electricity (by cost to run) than my gas boiler used to. There were a couple of glitches during installation but the Project Manager was very proactive in coming up with solutions which I believe cost AIRA extra, but no complaints from their side. There was some post-install snagging but engineer ANDY wouldn’t rest until these were all solved. So a few weeks inconvenience, true, but now all is good. I think AIRA did a good job overall. They also handled the whole Government Grant side of things so I paid for less than 50% of the system value.

Quick straightforward planning and installation. Aira stood by initial quote despite deciding to install a larger heat pump and more radiators later in the design process. They were also very understanding when there was a delay in money coming from a government grant and loan. One slight troubleshooting issue following installation was sorted almost immediately. Great service. Great people. The product has worked perfectly. I don’t know how we coped without it.

Process from survey, quote and to installation was excellent. Now, we are off gas and supporting Climate action whilst living in a warm house. With Octopus Go and Cosy, bills are no more expensive and probably cheaper than on gas. And once electricity pricing is reformed to reflect the lower and less prone to tutors party influences of Gas then this will be even better. So forget Daily Telegraph nonsense and switch now!

First of all, I'm extremely reluctant to leave a review that is critical of any business. I've only done it before to warn of a scam. I've thought long and hard before leaving this review. For me, the test of how good any business is is how they behave in the event something goes wrong. Do they resolve the problem? I originally had a Heat Pump installed by Aira in June 2024. That was followed by the Aira Solar and Battery in November 2024. There were problems with both installations, but I'll talk only about the Heat Pump here. The Heat Pump system was a mix of excellent planning and suboptimal installation that took longer than originally planned and left a long snagging list. To their credit, Aira did return on multiple occasions to fix all the snags to my satisfaction. But the system does not work. For a long time, the system pumped out excessive heat and could not be stopped. This has been partially rectified. (the sensor in the buffer tank not inserted fully issue). More recently, the system demands huge amounts of energy and supplies excess heat when not required. The thermostat seems to have no material effect. When this issue was raised, I believe their tech support changed something remotely. Now, the system struggles to maintain 17 degrees and will just not warm up. Out-of-hours calls are answered but never followed up. Customer Service, during office hours, seems to care little about no heating nor inability to meet their "comfort guarantee". Avoid.

Following our brilliant installation on the 7 March, we had Charlie and Ryan (Operations Service Manager), back on site for a couple of days to iron out some teething problems and true to form, they were yet again outstanding. Stripping down my UFH manifold, replacing old valves and flow meters, resolving a flow issue with my main bathroom, flushing the entire system and balancing it again with exquisite precision. So glad I chose Aira, out of my 5 contenders, and got the 15-year peace of mind parts and labour warranty, which I have already needed to access and they delivered. To my mind, these guys are the John Lewis of Heat Pumps and I feel very supported by the Facebook customer group called ‘AIRA heat pump owners UK’, which is friendly and supportive. John, Asher and Kishore were first-class ambassadors of Aira, working with total professionalism, creativity, flexibility & tenacity. Each and every day they were working by 8am and some days did not finish until 8pm without taking a break during the day with Kishore the electrician, putting in an 8 am to 11 pm one day. Nothing was too much trouble and this team truly went the extra mile. Based on the quality of Aira's Heat Pump, their exemplary service and the deep knowledge and experience of their System Design Engineers, installation teams and on-call engineers, and their 15 years warranty, I have no hesitation in recommending them as the first choice for heat pumps.
