Sustain Heating and Renewables Ltd

The design and discussion of my PV system with Peter, the installation by Daniel and Scott through to the commissioning by Will has happened without any problem, damage or issue. A long discussion of my requirements and a detailed Q&A session led to agreeing an 18 panel system spread over two roofs with external batteries and inverter. The price was agreed, the date set and the system was installed over three days, as planned. Their attention to detail placed the panels centrally on the roofs so they look as good as they can and the electrical cabling and various boxes installed with a minimum of fuss. We are pleased with our PV system, believe it was value for money and feel it was a much easier process than we expected. I have no hesitation in recommending Sustain and should add an addendum to this review in a year's time to reflect on whether the performance reaches our expectations. For info: we have a 1954 detached house

Sustain Heating did an amazing job fitting the Air source heat pumps, replacing the old radiators with new efficient ones, removing the old gas boiler. It wasn’t an easy job in my stone-built 400 year old house on 4 floors, and they dealt with the unexpected problems with ease. They were great communicators and it was a really positive experience having them do this very complex installation

I was particularly concerned about installing an ASHP as there are many horror stories and much misinformation flying around. I met Sustain Heating at the Malvern Show and was encouraged by their approach and knowledge. We had quite a few visits from Sustain prior to the installation to ensure everything was in order. I was particularly impressed with the manner in which they ensured we were aware of all the safeguards and processes they have in place to ensure that the system is reliable and efficient. The installation proved a challenge but at no time did I feel that the guys didn't have a grip on it. They kept me informed throughout the process. What I found encouraging was that all their fitters, none of whom were sub-contact, were fully trained and were able to answer all my queries. The system is up and running and, although early days, I am happy with the outcome. I have been particularly impressed with the manner in which my subsequent queries have been dealt with. I have no hesitation in recommending this company.

We have waited a year before writing this review. We had solar panels and battery fitted and have been delighted with the performance of the system. Saved hundreds of pounds in the first year. Dealing with Sustain was a painless experience. The initial meeting with Peter was informative and all of my wife's extensive(!) questions were dealt with. The scaffolding was put up without fuss. We did have to push for it to be taken down (3 weeks after installation). A minor hassle. The guys who installed the panels were heroes! Torrential rain, but they stuck at it. Done in a day. The inverter was installed and set up two days later, along with the boost for the water tank. Neat and tidy. Up and running in less than a week! Very pleased with any responses we have had to queries about the system, made us feel that we were being looked after. All in all I would not hesitate to recommend Sustain as an efficient and highly professional company

Sustain were contracted to replace our solid fuel system with a heat pump. We already had underfloor pipework, so this was basically disconnecting the solid fuel system and replacing it with a heat pump system. It included replacing an existing thermal store with a heat-pump cylinder and replacing the old underfloor manifold ( which was faulty) and then running pipework to connect up the new system. All was accomplished in 10 working days as had been predicted (it was quite a big job) and finished in an exemplary manner. On more than one occasion there were 3 vans on the drive with the Sustain guys working around each other. Of particular value was the fact that Sustain were happy to fit around our timing plans, which were complicated by an unexpected occurrence. I'd have no hesitation in recommending them, but since I found them through Which Trusted Traders, this doesn't surprise me.

When I reached out to Sustain in the summer of 23, I wanted solar on one side of the house. This proved difficult based on the roof layout so I cancelled the order. They convinced me using both sides would still give me the results I wanted. We went ahead with the 5.6kw system with panels dotted all over the roof and garage roof. I had a SMETS2 meter installed by Octopus Energy in January 24 and since then I haven't received an energy bill, instead they pay me (from Feb onwards). With the help of Sustain I have future proofed the house with very low or non existent electricity bills. The lads who installed the system were respectful of the property and did an excellent job. I couldn't be happier with my Enphase solar system.

Sustain did a total heating system conversion for us, replacing 2 gas boilers with a Grant ASHP and MyEnergi Libbi solar PV battery storage, including 2 EV charging points. Everything from initial consultation to to the installation and commissioning has been 5 star. The crews were incredibly professional and the work completed to a very high standard. Sustain were great at keeping us informed and even managed to complete the project ahead of schedule. I would highly recommend Sustain for all your renewable heating and energy needs.

Excellent company. Heat pumps, solar PV and solar thermal all installed professionally and competently. Very pleased that the heat loss survey was done prior to heat pump installation to ensure that the system will meet our heating needs.

I have no hesitation in recommending Sustain. They know what they are doing, helpful, quick to respond and professional. It's a big deal having a totally new system installed in to your home and they take you though it step by step, always ok with answering lots of questions. It's very new and they are still available for aftercare. Thank you Sustain

We recently decided to remove our 20 year old oil fired heating and hot water system and install an Air Sourced Heat pump. Researching which company to use is time consuming and at times confusing. We approached a total of 5 companies for a quote. All except Sustain gave us a figure down to the nearest pound, with either no visit to the house or a cursory sales pitch on site. Sustain stand out as the only company to insist on a comprehensive third party heat loss survey being carried out before designing a bespoke system, schedule of works and quotation. It was this systematic and logical approach, together with the approachability and professionalism of everyone involved that convinced us to go with Sustain. The resulting installation has been completed to an extremely high standard by a most friendly team who clearly know exactly what they are doing. There have been a few “snagging” issues but all have been satisfactorily resolved with the minimum of fuss. The heat pump warms the house beautifully and we have a plentiful supply of hot water. Sustain is an extremely well run company with a family feel. Not too big so that you are just a number but with just the right economy of scale. The company owner even visited himself to explain the schedules of works and was always on hand to help the system settle down. I cannot recommend Sustain highly enough and would strongly urge anyone thinking of installing a heat pump to use them.
