Eco Installer and Service Ltd Reviews 

This company is very well run and efficient. The engineers are top rate and go about their work professionally. The back office staff get appointments organised quickly. I will continue to recommend Eco Installer to others.

Chris arrived on time and carried out a full service of our ASHP. He also took the time to explain the difference between ECO Installer's specialists, how they collaborate and the values and attention to detail, from top down, that singles their company out from others. This only confirmed what we'd already thought about ECO Installer: we are in the best possible professional hands. Thank you!

Came to do annual service of heat pump and aircon units inside and out. Prompt per appointment. Engineer was friendly and happy to do an additional piece of work on under floor heating and even had the necessary spare. Great service from Engineer and the office who were in contact in advance and confirmed the extra work was ok to proceed so saved us a 2nd visit.

EcoInstallers stepped in to fix some issues on a complicated ASHP installation caused by another contractor. They were unbelievably helpful and knowledgable and did an excellent job.
They have maintained our equipment for the last three years.
A great team. And a very happy customer.

EcoInstaller replaced our old ground source heat pump with the latest model a year ago, and have maintained it since. First-rate service, both from the team on site, and the staff back at the office—everybody friendly, knowledgeable, good humoured and efficient throughout a complex process. Strongly recommended.

I cannot praise Eco Installer high enough as they have always provided us with a superb service. Ever since they installed our Air Source Heat Pump in 2020 they have serviced and repaired our system effortlessly. The latest problem we had was on New Years Day where our system would not heat up. Despite it being a Bank Holiday the office team responded to my (very hopeful) email sent on January 1st asking for help and Chris, an engineer who we have become to know well, was dispatched first thing to us on January 2nd. He diagnosed the fault quickly (a faulty motor on a 3-port valve), replaced it and waited to check that all was well. If you are looking for service excellence you will not need to look further than Eco Installer here in the Cambridgeshire area (and wider).

Had our annual service on our underfloor system and repairs for a faulty thermostat. All done with very speedy and efficient time, found Chris to be very knowledgeable and very polite, also Annette very excellent with her manner and very very helpful. Would endorse anybody who uses them .

Been using Eco Installer ever since they installed my heat pump 7 years ago as I find them to be knowledgeable in their field, professional, friendly, punctual both onsite with the engineers and in the office. The engineers also tidy up after themselves too.

recently eco INSTALLER fixed us up with solar panels, an inverter and a battery . . they have a good design based on FoxESS systems and components but not a 'one size fits all' approach as they were happy to discus options and respond positively to our requests . . installation was smooth, essentially taking just one day and scaffolding was taken down promptly . . back at the office all handover documents arrived promptly so that we were able to satisfy UK Power Networks and be added to the Smart Garantee Scheme
all our questions were dealt with promptly and the installion engineers went out of their way to be pleasant and provide the solution we were looking for

Very helpful arranging appointment and making changes. Gave me a discount for booking in summer and passed on discount for being local to staff.

Service for our ASHP, very good result and first class processes. Engineers are very knowledgeable and answered ALL our questions.
Happy to be a regular customer.

I have been using Eco Installer for a number of years now. They installed our ASHP system 5 years ago and have serviced it yearly since. They have always turned up when they said. Always polite , friendly, professional and knowledgeable. I would definitely recommend them.

We've been Eco Installer customers for four years. They installed our heat pump and have serviced it every year. They have always been helpful and reliable and respond quickly to queries. I'm pleased to recommend them.

Lovely people, very helpful.
Offered to talk to builders about faults they had found with the installation at my new build.
Didn't make out work needed doing when it didn't.

I asked Eco Installer to review my ASHP installation and they did this, giving me useful advice on what small changes could be done to ease servicing etc. Full marks for servicing (3 years) and pragmatic, honest, advice. Much appreciated.

Eco Installer have given good advice for us building a new home with them supplying the MVHR, Air source water and under floor heating and now give a regular checkups. Always friendly and helpful.

It is a pleasure to review this company,,they were efficient, not expensive.2 very nice friendly lads,,did a brilliant job ,,they are in my favourites for any future problems....,,would highly recommend them...it was in January 2025.

We had a heat pump service and some minor plumbing repairs. Mikey was thorough and fixed an issue with a diverter valve, which had been causing our radiators to waste heat in hot water only setting.

Mikey removed a radiator for me and installed a new one in a different location, he talked us through the process and was great throughout. Big thanks to Ashleigh for squeezing us in at short notice.

I had my heat pump serviced, and Chris did an excellent job. He not only completed the service efficiently but also identified a couple of issues with my heating system, specifically insufficient insulation on the outdoor pipework and a low antifreeze level. Following the inspection, he provided a clear and detailed report outlining the necessary remedial work.
