Excellent install with great care and flexibility

We spent a long time researching solar panels and fittings, holding out for a system that would look clean and discreet on our standing seam roof. The team totally delivered – the panels are ultra low-profile, beautifully fitted, and performing brilliantly. As well as the panels, we had an inverter, battery and solar diverter installed. Everything was integrated neatly and is running smoothly, generating loads of power without any issues. We had a couple of unexpected snags (including a pull-cord our builders had installed, which didn’t pull the electric cables through the wall cavity as planned), but the team were calm, flexible and helpful throughout, working around the issues without fuss. Everything was installed with care and attention to detail, and we couldn’t be happier with the result.

What an absolute pleasure to deal with such a friendly and professional team. From initial phone contact through site survey (by an independent energy consultant) through technical review and design, installation walk through, and finally the installation and commissioning of our new replacement air Source Heat Pump; the team at Sustain, every single one of them, were totally committed to getting the job done despite the difficulties posed by minimising disturbance in an 1850s stone walled cottage. I would have no hesitation in recommending this company.

Air source heat pump

The quality of installation of my air source heat pump was high, and Sustain Heating were responsive to my requests (mainly to ensure that pipework was as invisible as possible). They were quick to reply by email and easy to reach by phone. The time between first contact and completion of the work was short. Good value for the quality of the work. Highly recommended.

Highly professional work

I cannot praise too highly the professionalism of Sustain from start to finish of our heating project. Ours is a 1840 townhouse, five storeys, listed grade 2*, in a conservation area. Sustain commissioned an independent heating survey and built up the specifications for the project in order to meet our requirements for heating. There was an unfortunate 5-month delay while we obtained planning consent from the city council, and then we agreed with Sustain on a start date in the spring. Sustain completed the whole work as promised in eight working days, including two air source heat pumps, new cylinder and total upgrade of the central heating system. We are very satisfied with the finished result.

Heat Pump and Solar PV Installation
Customer Service

We commissioned Sustain to install an air source heat pump in 2023, after getting several alternative quotations. Sustain stood out by providing the optimum balance of system design, cost, and knowledge of the technology. After 2 faultless years of heap pump operation, saving us an estimated £600 a year on heating bills (previously an oil-fired boiler), giving us a very cosy warm house, we started looking at the possibility of having a PV solar system installed. Again, Sustain stood out as the best company in terms of cost, size of system, and technical expertise, after having detailed discussions with 2 alternative suppliers. We are very glad that we again chose Sustain for the PV system. Sustain's staff, the roofer, electricians, and office personnel were very easy to get along with and a pleasure to have on site.

We had air conditioning installed by Sustain. From our initial request a site visit and quotation was supplied promptly, followed by installation which again was carried out by people who know their job and were always polite and friendly. Our home was left clean and tidy with all the packaging etc removed, the air conditioning fitted is superb. It was a pleasure to do business with Sustain.

I cannot recommend Sustain highly enough. The customer service and quality of advice was top notch from the start. Knowledgeable people throughout the whole process,kept us fully informed and involved. Installation happened as planned and in a timely manner. Those who came to site were a pleasure to have in the house (and on the roof!), and our batteries and panels work a treat. A top class experience, outstanding service and a pleasure to deal with.

Sustain arrived on time and worked hard to install my heat pump

Sustain arrived on time and worked hard to install my heat pump. All of the plumbing is very neat and it all works as expected. They also managed to include my existing Solar Thermal panels. They replaced everything except the panels and I now have a warranty that covers the whole system. The lads could not have been more helpful and I have no hesitation in recommending them

An excellent company in every respect

Sustain have over the recent past installed both solar panels and an air source heat pump system. We are absolutely delighted with the products and the service received. With regard to the air source heat pump project nothing was too much trouble. Glenn, Richard, Alex, Ollie, Will ,Adam, Daniel and Tony went above and beyond what might be expected. When a glitch was discovered Glenn stayed until 9pm to sort it out successfully despite facing a drive in excess of one hour to get home. After installation head office support has been readily and cheerfully available. When we were investigating this project, Wayne, Peter and the ever cheerful Geraldine were very helpful! We recommend this company without reservation!

Solar Panel Installation

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
