Sustain Heating and Renewables Ltd

Sustain installed a 16 panel PV and battery storage system last month, and it is perfect. From the initial sales visit through to the quote to installation (in 4 weeks, the largest delay was waiting for grid approval) the whole process was smooth and efficient. Particular shout out to installers Callum & Scott and electrician Lucasz who were professional, friendly and helpful, consulting us an all aspects of the layout etc. We have no hesitation in recommending this company.

I recently had an upgrade of my heating system to an Air Source Heatpump. After much research I went with Sustain Heating and I am very glad I did. From the very outset I could tell that I was in safe hands and everything was explained clearly. The teams (plumbers,electricians) who came to do the work were a great bunch and left everything clean and tidy. The system has been in for just over 2 weeks now and I could't be more happy. A minor glitch at the outset was sorted out quickly and I know that if I should experience any problems or concerns that I can call Sustain at any time. So nice to find a company with proper values and customer service! Date of experience: 19 February 2024

Sustain have installed a co-ordinated system for our house, incorporating an Air Source Heat Pump, existing solar panels, 2 x 5v batteries, a car charger and all the necessary controls. Everything works seamlessly. They have been, polite, careful, professional, skilled and competent and really care about our system. We are so glad we chose them and are confident that they will sort out any problems should they arise. Many thanks.

Sustain's fitting and aftercare for our PV system and batteries have been outstanding. The personal care and monitoring of the system has been exceptional and response to any questions or issues has been prompt. Also, you generate electricity and save money.

We are really pleased with the work that has been carried and the pump is doing a great job although it's not winter yet, obviously, but we've tested it and the heat is good as is the water heat and flow. The work was a little later getting started that we were expecting but once the guys were here they did a fantastic job and worked incredibly hard turning up first thing in the morning and often working through lunch. I've had bad experiences with contract workers - builders etc. in the past - bunking off to other jobs but not in this case. It was a difficult job as it was for the main house and annexe and so a lot of pipe work and ground work. A huge channel had to be dug and a lot of mess dragged out and I thought it would be left behind but no, everything was taken away and it is as good as new. All of the packaging too was taken away and you'd never know anyone had been here working. There were a couple of small hiccups but all sorted. I've had to make contact with the company a couple of times to ask questions and these have been answered quickly. I can't fault the guys doing the job.

We chose Sustain to install an air source heat pump for central heating and hot water after going through a list of firms provided by Vaillant (we had a Vaillant gas boiler at the time) and having site visits by three firms. We chose Sustain as the best without having read reviews, but these confirmed our decision. The installation was done over six months after we signed the contract and paid a deposit, but this was mainly because we did not want it done in the depths of winter. The work was carried our efficiently, and with consideration for the elderly homeowners (my wife and myself) Given that the firm was replacing an existing gas central heating system in a 400-year-old house the job was done even more satisfactorily than we expected, and our worries beforehand proved unnecessary. It took a little longer than anticipated, but snags had to be overcome, and two weekends and two bank holidays intervened. Our only criticism is that some new pipework holes were not made good - a minor point. The men were helpful and kept us informed throughout. So far we have been very pleased with Sustain. The real test of the system will come next winter!

We have had Sustain out to fit our air source heat pump initially (in Dec 2021) and then to install Solar PV with battery storage (in May 2023). On both installations they have proven to be experts at what they do and treat the customer with utmost care. With the heat pump, the installation guys retrofitted into an existing gas system which involved replacing some pipework and adding some larger radiators following recommendations from a heat calculation survey prior to the installation. This, along with the heat pump Sustain advised for us, meant that we now have an efficient and eco-friendly (with the 100% renewable energy electricity tariff we are on) means of heating our home. Sustain were brilliant throughout the whole process, with spot on products chosen for the job and constant communication from the installers throughout the process. We then looked to install solar PV and batteries to further improve our home's green credentials. We didn't hesitate to chose Sustain again for this and we weren't disappointed. The installers were knowledgable of their trades and were friendly and spent time going through what was being done to ensure we were kept in the loop. Aftercare has been fantastic too. Minor teething issues with our heatpump soon after it was installed were dealt with immediately by Sustain sending out a technician the same day when it was apparent we needed an expert to look into it further. Highly recommend this company!

After getting quotes from 7 of their competitors, I decided to go with Sustain, and am very glad I did! All stages of the process was flawless, from initial planning, installation and support on how to optimise the use of my solar system. Highly recommended

I chose Sustain to install solar panels and air source heating. They were prompt to respond to my enquiry and within 6 weeks my order was submitted. This compared to 2 other companies I made enquiries with who took nearly 6 months to respond and 2 months to reply to any emails! Sustain have been superb from the beginning. Arranging timely appointments to view, assess, discuss options etc. Once signed up they completed and submitted all relevant paperwork from beginning to end. The installations were separate. The solar panels were first, fitted in one day in January and the final electric connections, including 2 batteries, completed 10 days later. No disruption. A run through of the app and how to monitor my solar power completed at the same time. Excellent. The air source was initially planned for late February but that did change to the 2 weeks over Easter. During the intervening time I was kept informed and as mine was a retrofit there were a number of visits to check proposed pipe runs, tank sitings, radiator suitability etc. There was a lot to do but by the Thursday after Easter , with minimum disruption, my heating system was fully commissioned and I had been briefed on how best to run my system to suit me. There were follow up visits after installation to check I was happy with how things worked and everything was okay. I can also call anyone of 4 people to get advice at anytime. I have already recommended Sustain to 3 other people and will continue to do so.

Highly recommended. A smooth installation by a conscientious and friendly team including the scaffolders, panel fitters and electrician. All completed in a timely fashion with minimal disruption and no glitches or hidden costs.
