A Great Experience

I had Solar panels and a battery installed by Sustain. They were very good in sales information, giving me all the information that I needed to know and what differentiated them from their competition. I chose them over a rival and was not disappointed. The work was carried out over the two days as promised (although the scaffolding was left for over a week, apparently they contract out fitters). Been very happy since installation. Great customer's service, especially when I wanted to understand what was going on and how to calibrate it to my own needs.

Effective planning and installation of my solar system

Sustained Heating and Renewables installed my solar panels, batteries and inverter in July 2023. The detailed planning and discussion of options were thorough and informative, and I am confident we found the best possible solution for my situation. From then on Sustain handled the planning application and all the necessary prior to installation. The installation itself, was quick and very professional. Others have since commented on the thorough work done. Since the installation my electricity has cost virtually nothing, as the panels have delivered enough electricity for my needs and allowed me to export sufficient electricity to cover the standing charge in all but the darkest months (November to February). I can thoroughly recommend the company. Their quote was competitive (if not the absolutely cheapest), but what won me over was the long guarantees for the installation and the attention to detail during the planning process.

So very pleased we used Sustain Heating and Renewables for our solar upgrade. We had a false start with another company who turned out to be terrible, so started off nervous, but everyone we dealt with at Sustain were welcoming and reassuring. They took time to go through all our concerns and everything we wanted and translated it into a bespoke system. The team did a thorough and excellent job, including removing and disposing of the old system, meticulously patching and repairing the roof and installing new panels and batteries and all the electrical gubbins to make it work. The whole team were extremely professional and delightful to have around and they all clearly knew exactly what they were doing so were able to explain every step. All of them clearly took great pride in their work – a refreshing change from contractors simply following instructions. And Daniel was always at the end of the phone to answer any additional questions, and still is as we get used to the new system. We now have a top-class system that generates electricity even on a dull day, heats our water, charges our electric car and lets us control it all from an app on our phones. We would urge people to beware of inadequate companies hiding behind glossy brochures who turn out to be incompetent. Sustain Heating and Renewables are a fabulous small family business who have done an excellent job for us and we highly recommend them.

Superb Heat Pump installation by excellent company: Results in lovely warm house

We chose Sustain for our heat pump because (a) we were delighted by their installation of solar panels for us and (b) they were the only local firm prepared to fit a Viessmann R290 pump, top-quality German engineering. The team fitting our system had just been trained by Viessmann. Although Sustain would have provided us with heaters, we chose to rent locally. We popped in almost daily and were most impressed by the care taken by the team, and at conclusion, the house was left spotless. After 8 days of no heat, it took 2-3 days to bring the house to a lovely temperature everywhere. Sustain's calculations of which radiators needed enhancing have proved spot-on. Hot water is plentiful and shower pressure excellent. We live in a dormer bungalow with low eaves, and we could have been better forewarned that this would mean a vast array of exposed pipes from the quite elegant tank enclosure. The pipes have now been beautifully covered by a local curtain firm, but are still accessible for service. The large and amazingly quiet pump is outside and we have planted trees on either side to encourage birds and butterflies. The system is controllable world-wide by an uncomplicated smart-phone App, and by thermostatic radiator valves. it's too early to comment on running costs, but as heat pumps are much more efficient than gas boilers, we expect significant annual savings, while doing our bit to save the planet for our grandchildren and yours. We highly recommend Sustain.

Perfect PV installation

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

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.

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!
