Sustain Heating and Renewables Ltd

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.

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.
