Sustain Heating and Renewables Ltd

I can't rave enough about this company. They have done our air source heat pump and we have paid the deposit for solar panels. Every step of the way communication and customer service have been great. Any concerns, issues, etc. They respond right away. Did fantastic work and really just an all around great company. Even moved out install up a few weeks because they knew we didn't have any heat and did the whole thing incredibly quickly.

Sustain installed all black solar panels split between east and west facing elevations plus a three phase FusionSolar home battery system with backup function for power outages or cuts. The installation is really neat. I have had neighbours from my estate that I dont know knock on the door to find out more attracted by the way the panels are installed/look. They also are impressed by the slim profile battery system which is mounted on external wall alongside the meter boxes. The installation was really quick and guys worked really hard. The scaffolding was installed just before installation and taken down a few days later. A very smooth operation. Now we are into september with cloudy skies I am really impressed with how well the system works and I am expecting it to make a big difference to my energy costs and my carbon footprint as I also have an ASHP. I approached other Which trusted traders and they were not as responsive as Sustain and the ones that did respond were not as technically aware as Sustain in their proposals. We are very pleased to get this system in.

As a Which member I looked for a Which Trusted Trader for my projects. I contactted five trusted traders and one other large national company. The large national company came to the house to present a quote to us. We laughed after the salesman left - it was far from value for money (caveat emptor). Two trusted traders responded fully to my request for a costed solution. I selected Sustain on technical considerations and overall ease of dealing with them. The team worked really hard as there were some really hot days at the time and a lot of instalaltion work took place in the loft. A major rework of the plumbing was necessary as the existing was far from standard design plus microbore. Install included a water cylinder in the loft, combi boiler plus gas fire removed and gas supply capped. They dug a trench in the garden for the services for the heat pump and even took away the spoil. They installed a Mitsubishi Ecodan system which works really well. It heats the hot water very quickly and playing around with the controls I managed to get the house far too hot one morning in the the recent colder spells (much to the ire of my wife), so the system definitely heats the house. Sustain are very responsive to any querries plus there is a free homeowner support line provided by Mitsubishi which is excellent - no question too stupid! We are very pleased with the end result and I must admit I was very apprehensive initially. The team were very friendly and helpful throughout.

Sustain Heating installed an Air Source Heat Pump system for us to provide heating and hot water in our house which is an old stone farm building. They provided us with an excellent service in every way. This included: - A detailed estimate and prompt replies to queries. - A pre-installation visit when all the key issues were agreed, such as locations for all elements of the system, routing of pipework, etc. - The installation itself was done by a team who all knew each other well and worked well as a team. They were all polite, worked hard and kept us informed on the work planned each day. - Detailed decisions were discussed when appropriate before the work was done. - Tools were put away and the house was left tidy and clean at the end of each day's work.

We had a major solar PV installation completed by Sustain this April. We chose Sustain because they are Which? Trusted Traders and they were helpful and responsive to enquiries. (Another WTT solar firm rejected the house as unsuitable based only on looking on Google Earth!). As we have East and West facing roofs, we accepted Sustain's suggestion of having twin installations and a large battery. Our main motivation was ethical, but we were fortunate that the price difference between selling a London house and buying in North Somerset, enabled us to make the investment painlessly. The planning and execution of the work was excellent and we were kept in touch all the time with progress. The actual installation took about 2,5 days only. In practice now, in these days of maximum light, we use no paid for electricity at all, and a total of less than 1kw since April. In these days of energy crisis, Briish Gas has reduced, not increased our monthly standing order. So we recommend Sustain very highly. They are not perfect and in our case still need to do more to explain to a couple of OAPs how to get the best out of the system and the App, so they score 90%, but we'd certainly have them again and their staff are polite, skilled and helpful.

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.
