We wanted a heatpump and new tank installed and were recommended AES, the office staff were very friendly, the tech guys very knowledgable and initial work carried out smoothly. they are much in demand so getting a install date is a little tricky so plan ahead. we had some issues with the system (component parts not the install) which required a number of follow up calls, visits and extra parts to cure. At no point did we feel fobbed off or a nuisance, quite the opposite. we will be using them to install Solar in the new year, that's our recommendation.
Getting a quotation and booking in the work was a very good experience The install guys were fantastic. The after documentation and getting the MPAN number for the exporting was lengthier than expected. Really pleased with the system and the way it is performing.
We have our air source heat pump and new solar panels for over three and a half years and recently propped up the battery power with AES. Overall we are very happy and grateful for their work. We had a few issues at the start when AES could not find the right site for the heat pump and we already dismantled our greenhouse to fit the pump, but in the end AES found a much better location and di all the plumbing and installation works very well!
our air source heat pump was installed years ago by another company who went out of business, AES attended on our request because it seemed intermittent and hadn't been serviced for several years. AES took all the details and identified several failures which needed urgent attention. The repair was done, and all became reliable again. The engineer was speedy in putting things right, and left us with good advice, we are now on the annual service. We received several follow up phone calls from polite knowledgeable people.
⭐ 5 stars — Excellent service from Henri AES Contractors Ltd supplied and installed our solar panels, battery system, inverter, iBoost and bird guards in September 2025, and already the benefits have been huge. We are saving money every month, especially with electricity prices going north, and the whole setup has made a real difference to our energy consumption. The installation was a breeze, and throughout the entire process AES Contractors Ltd have been consistently supportive, reliable and knowledgeable. Any queries I have had have been handled exceptionally. After installation I reached out and Henri responded calmly and reassuringly. His manner makes everything fully straightforward. The system they installed is solid, high quality, and their ongoing customer care has been exceptional. I fully recommend this company 😊
