Sustain - Solar, Heat Pumps & HomePlans Reviews 

The lads were great! Got straight on with the job and were done in a few hours. They were helpful and respectful to me, and showed how everything works after the installation

The service and speed with which Sustain dealt with our issue has been second to none. Extremely willing to help, to find and fund a solution when initial inspection seemed to indicate no fault. Happy customer who would not hesitate to recommend Sustain to anyone who asks.
You could perhaps argue that the fault shouldn’t have been caused in the first place but I judge a company by how it addresses the abnormal, not so much on the day to day, which should be straightforward anyway.

I had an ASHP installed in April 2026 over a 4 day period.
The Sustain team were excellent- Jacob and Taylor were helpful, sociable and polite - they worked hard and kept me informed at all times on their progress. They tidied up each afternoon before leaving.
The electrician (Tom ?) was here for the 1st day and was equally pleasant and efficient.
From the outset, I was impressed with Adam who visited to prepare the design and price and gave me confidence that it would be a good decision to replace my old oil boiler and hot water tank and that the new ASHP would work effectively with my underfloor heating.
Ryan has also been very helpful with answering queries since installation.
So far, so good as regards electricity usage/cost where, even excluding the recent massive increase in heating oil costs, it seems that I will make savings when compared to the previous oil plus electricity bill.
I would highly recommend Sustain Homes.

I have been critical of this company before but their response to my criticism was to immediately sort out the problem. Their engineer, Charlie, even came out early on a Bank Holiday to find out what was wrong with our system and to put it right. It is a shame I had to first have a grumble on Trust Pilot before things happened but there is no doubt that the company did everything they could, very quickly, to put things right.

Solar panels & Air source heat pump installation.

All the contractors were amazing.

There was a 7 day tight deadline to work to.

All works completed on time to an excellent standard.
Contractor all so friendly, informative, professional and tidy.
Vulnerable adult 91 living at residence at the time of installation. I was worried about her being warm as doors needed to be opened and this week in March was quite cold.
The contractors worked around her ensuring she was kept warm. So grateful to them for this.

Highly recommend
Great work
Great team

Thank you again Sustain Homes Ltd.

Excellent service from start to installation and commissioning. Kept in the loop. Great engineers who knew exactly what they were doing. Highly recommended.

Cannot thank sustain and their superb engineer max who sorted all our issues very quickly, professionally and with minimum fuss . He was extremely knowledgable in his field and left us very satisfied with the job done , a valuable asset to sustain .
Thanks again .
Mr S Walsh.

Installation of solar panels was smooth and completed in a day with easy lead up communication with a dedicated contact. No issues or stress and would recommend.

I had solar panels and battery installed by the team from Sustain and can highly recommend this company. Throughout planning, installation and communication they were professional, efficient and very friendly.

Done a great job I'm saving g a good amount each month happily surprised.had a man called Simon come today to help me set up revenue

We just had a solar power system installed with six PV panels and a battery. Scaffolders arrived at 08:30 as expected on Monday. They were super efficient, courteous and considerate of our property. The scaffolding was all up in a couple of hours and they left at 11:00am. Then, also as planned, the roofers, electricians and the kit arrived about 08:45 on Wednesday. They worked flat out, were also very helpful, efficient and considerate. Our new panels went live about 15:15, and we’ve been off grid or exporting power to the grid ever since. We’re expecting the scaffolding to come down in a week’s time. This has been a really positive experience. The system installed is superb, good value, and we can’t fault the guys. This company deserves its good reputation and we’re very happy that Scottish Power are contracting them.

A big thank you to the Sustain team for their amazing aftercare. I had a fault on my system which they installed about three years ago - I had spoken to Fox who had done all they could remotely and they suggested speaking to my installer - the sustain team were out in a couple of days, fixed the fault ( which was caused by me moving a cable!!) and had us back and running in a couple of hours - absolutely top company with friendly and helpful staff. Thank you :)

Many thanks to Charlie, Adam and Guy and of course Chris Dylan and Frank. Great team work have done an excellent job installing our heat pump. It’s been a pleasure to have them working for us….very professional and helpful. Thoroughly recommend them.

I recently had an issue with my solar battery not working and contacted Sustain for help. Their response was exceptional from the very start. They arranged a visit at very short notice, and the level of communication throughout was first‑class.
The engineering team arrived promptly, quickly isolated the fault—which turned out to be a communication cable back to the CT clamp—and replaced it with zero mess or disruption. Everything was handled professionally and efficiently, and I was back up and running in no time.
A special thanks to John, who organised everything seamlessly, and to Sam, whose expertise in identifying and fixing the problem was outstanding. It's rare to receive service this good, and I couldn’t be more impressed.
Highly recommended!

Laurence at Sustain has been brilliant to work with. He has been helping us plan the installation of an air source heat pump as part of our home renovation and has been incredibly generous with his time and expertise.
He has taken the time to explain everything clearly, answer our many questions and help us think through the best options for our project. His knowledge and professionalism have given us real confidence moving forward.
We are very grateful for his support and would happily recommend him to anyone considering a heat pump.

All went well at the start but the aftercare isn’t there. I am actively losing money because they don’t respond to queries. I have called and messaged but there is no resolution

The Sustain team installed the panels to my satisfaction and kept me informed along the way.

I was impressed with Sustain when they installed a solar and battery system in 2023, and upgraded our batteries last year. Sam and Maddie were quick and effective. Not so impressed now, with no response after a week to an email asking for specific support, and nobody seeming to answer the phones.
I appreciate the follow-up and explanation in response to my review.

Outstanding experience from the first call to the final installation of our high-temp Samsung heat pump and Adia system. We never thought it would be possible to achieve such even heating throughout our flint cottage, but the results have been incredible. Even through heavy frosts, we have been perfectly cosy.

A particular shout-out to Laurence, who handled our design; Ryan, who managed the prep; and Jacob, Freddie, and Taylor, who worked tirelessly on the install.

The addition of the Adia system was a game-changer for us, allowing us to:

Minimise disruption: We had to change far fewer radiators than expected (bought 2 larger ones)

Total comfort: The sensors and controls provide perfectly even heat across the whole home.

Cost efficiency: The smart learning features optimise our heating based on our specific tariff.

I could not recommend this team highly enough.

We have not yet made a decision on converting our heating to an air source heat pump but the process of getting a quote from Sustain has been excellent. Adam - our contact who also did a site visit was open, honest explained the complexities very well and was a pleasure to work with.
