Sustain Heating and Renewables Ltd

I would definitely recommend Sustain Heating and Renewables. They have recently installed a solar PV system to our property and have been very professional throughout. When there was a problem with the inverter post installation, it was dealt with quickly and the issue has now been resolved with a new inverter fitted under warranty.

We have just been through our first winter with a Vaillant Arotherm Plus air source heat pump installed by Sustain last June. I am pleased to say that our home has been warm and comfortable throughout the past winter and we have always had plentiful hot water, even when visitors have been staying. I think this is the mark of a well-designed and well-installed system. After-sales service to sort out two very minor snags was excellent and Sustain responded to my call very quickly even though it was the beginning of winter and the company was very busy at the time. I thoroughly recommend Sustain Plumbing and Heating.

I am pleased to write a positive review for Sustain Heating, investing quite a lot of money on a system I was fairly unfamiliar with was a bit nerve wracking. My worries turned out to be completely unfounded, Sustain Heating completed the installation with the following positive points and no negative points. There were no hidden costs, the price quoted was the price paid. The work was carried out on the promised schedule with small amendments closer to the time but with full upfront communication and agreement. Panel changes due to global demand and delivery issues from the original quote were notified upfront and the Longhi panels finally purchased with the order are by no means substandard from the original proposal. The workmen, scaffolders and electricians (Fully MCS qualified) were all very courteous and extremely helpful in explaining the purpose and use of each item of equipment. The support from the Sustain office was pretty much immediately available. Queries from their on-site staff and myself were answered very promptly. All administration paperwork for permissions for National Grid access and MCS certification etc. was all completely handled by Sustain Heating In summary, I would not hesitate to recommend Sustain Heating to anyone considering a solar PV panel installation.

Sustain installed 21 all-black solar panels over my south-west facing roof space along with all required infrastructure - batteries and inverter. I started with 5 quotes and lots of discussions before finally choosing Sustain for my installation. Explanations with regards installation and pricing were crystal clear and once started the installation progressed and concluded as expected. In a project of this nature and the current difficulties in supply chain links it was inevitable that some delays would be encountered. Sustain managed my expectations professionally and reasonably well and in the final analysis the projected completion and commissioning date was achieved. I had very minor issues with communications BUT nothing to warrant any significant comment. All in all, a very easy project to complete largely due to the very good works from all the staff at Sustain particularly the panel installers and the electricians - many thanks - thinking about an ASHP next!

This was a large project, involving solar panels, storage batteries, replacement of all the radiators and installation of an air source heat pump. All phases of the project were carried out very professionally and the various teams carrying out the work were always a pleasure to deal with. Although some phases of the project were quite disruptive, the teams tried to keep disruption to a minimum and worked as quickly/efficiently as possible. All the work has been performed to a high standard. To the extent that there have been any teething troubles, they have been solved promptly and effectively. The company really does want to install a heating system that the customer is happy with and is prepared to go the extra mile to ensure customer satisfaction. Overall, 5 stars!

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.
