Work was accomplished to a high standard whilst I was abroad even with covid restrictions and difficulties. They responded immediately on my return with small teething problems. It is now working better than the old gas system and I am extremely pleased with the result. All the stages were well explained and the grant approval system worked well due to the attention to detail they undertook.

We did lots of homework and spoke to several companies before choosing the supplier to install solar at our home. We chose Sustain due to their knowledge, help and reassurance they provided. They were the company we could trust. And I’m pleased to say that (after a bit of a delay waiting for the products to land in the UK) they delivered. It wasn’t a straightforward install and the weather wasn’t kind, but nothing was ever a problem and they did a brilliant, and very tidy job. I’m pleased to say the panels and battery are performing brilliantly and (now the weather’s improved), we’re reaping the benefits and tapping into renewable energy. Loving it!!

I first contacted Sustain last October and from the first conversation, I had a great feeling of confidence in their knowledge of my requirements and the reliability of their services. I have not been disappointed. The climate crisis, plus the rocketing cost of gas and now the need to cease using Russian energy have all contributed to my decision to convert from gas central heating to an electrically run heat pump system. Sustain has both provided this efficiently and been a constant source of help and information along the way. Heat pumps are quite expensive and at the beginning of my enquiries, they pulled no punches. I had an upfront breakdown of costs and information about the heat loss survey and energy performance check that would be required as well as much help in sourcing Government funding which over the next 4 years will pay for over half of my new system. As soon as I decided to go ahead I was given a rough date for installation as mid-February, but despite the pressures the heating industry is under, this was brought forward to 24th January. In just over two days my heat pump was installed with all the new radiators and was up and running most efficiently. Since then Sustain has also installed a storage battery which is charged on a cheaper nighttime tariff and also makes much more use of power from the solar panels I’ve had for a few years. All in all, I cannot recommend Sustain more highly, for all the help and information I had before I decided on

We had been thinking about having an air source heat pump installed for some time and once we had seen one in action at a friends’ house, we decided to get on with it. Going by reviews of local, specialist companies, Sustain Heating and Renewables really stood out and we weren’t disappointed – excellent service from start to finish, with home visits to explain what would be involved, through to the installation itself. Sustain also arranges all the necessary checks and documents, making the whole process simple and straightforward. Our installers did a great job, explaining what would be happening on a day to day basis; doing their best to inconvenience us as little as possible (we were never without hot water or heating when we needed them); keeping our house in a tidy state while they worked; and listening to our specific requirements, making small changes when requested. We live in a typical early C20 terraced house but our initial doubts about where the heat pump would be sited and how the new system would link to existing pipework were all dealt with in a most professional and reassuring way. We love our new system – responsive, simple to use, providing us with a warm house, masses of hot water and satisfaction of knowing we are using less energy. If you are considering switching to sustainable heating, we strongly recommend that you consider using Sustain. If our experience is anything to go by, you won't be disappointed.

From the very first contact with Sustain, we found them to be extremely professional and knowledgeable. We had many questions and at all stages they were promptly and expertly answered. They provided us with realistic timescales, despite the high level of work currently being undertaken to meet the RHI deadlines. The installers were clearly experts in their field and ensured that disruption was kept to a minimum. We are delighted with how well the system is working and would have no hesitation in recommending this company.

I have had my old dysfunctional heat pump replaced. The whole process was painless. From start to finish I always felt in good hands with people who knew what they were doing, which is so important with heat pumps, as one needs a firm with trained and experienced heating engineers. The communication was working well, Sustain´s plumbers and electricians did a good job, and their engineers Neil and Ashley were superb - picking up everything which needed tweaking and answering all my questions, giving me the confidence to work the system. All the necessary certificates and paperwork was provided and best of all, I know whenever anything goes wrong, I can rely on Sustain to come and fix it!

We are in the process of building a large 3 story extension and were interested in an air source heat pump for the extension only. After discussing this with Sustain we were told it would make more sense to change the existing house’s ancient heating system as well as we would get a better RHI return this way. Doing the calculations, made complete sense in the end when I had all the figures in front of me. The house was still on a one-pipe system so floorboards were all lifted and it was major upheaval. Joe and his team were amazing at working around me (who works from home) and causing a limited disruption even with such a big job. It took 9 days to complete the installation and I must say I can’t be happier with the whole process. I didn’t realise how bad the previous system was until the new one was up and running! Sustain has been super efficient throughout the process and I would definitely recommend them for anyone’s future renewable energy needs.

This review will be a little different to most, but in some respects may be more informative. We chose Sustainable Heating on the basis of the Which Trusted Trader scheme and we are glad that we did. We have given a five star rating but the installation was far from straightforward. The problems were mostly outside the control of the company but they resulted in the start of the work being delayed, with the installation taking longer than expected. The standard of the workmanship was high with the solar panels and battery installed on time taking only 2 days. The 4 week experience with this system has shown it's worth. The heat pump installation needed the replacement of over 90% of the existing central heating. The inevitable disruption and damage was far less than anticipated, the plumbing and pipework is really neat and to a high standard. The fitters communicated very well with both of us and discussed all aspects of the installation with us. During this time we spoke to Richard and Tony and it was very clear that their goal was to deliver a system that we would be pleased with. This they have done. There were some communication issues and difficulties but they were resolved. Heat pumps are not pretty but Neil, the senior engineer, arranged the pipework etc. to minimise its impact. Today, due to the recent warm weather, was the first time the heating came on for real, so to speak, and I feel confident that we've made the right decision.

Sustain installed a Air Source Heat Pump System at our property in May 2021. The work was completed on schedule and in budget despite some unforeseen challenges. From the initial survey before they actually commenced to the final commissioning the standard of work was exemplary. The work was carried out with the least possible disruption for quite a major amount of work and with courtesy and respect. The Mitsubishi equipment installed is of very high quality and is working very efficiently. The support staff at Sustain ensured all the relevant paperwork, surveys, etc... was all in place from the initial order placement to the final commissioning.
