I had both solar panels (+batteries) and a heat pump installed by Green Flare. These people really know their stuff, and will go the extra mile to make sure your installation is a success. The heat pump model they use is amazing, far better than the low-end models you get from energy suppliers (huge COP and extremely quiet). As for solar, the quote from my energy supplier said they could only fit 4 panels on my roof: Green Flare had a proper look and got 11 on there (and fixed my roof while they were at it!).
I needed a custom hot water setup (photo attached - pure craftsmanship) which naturally had some teething problems, but they were up to the challenge, tweaking and fixing until it worked perfectly. I absolutely recommend Green Flare and their products, and I'm very glad I didn't go with a generic one-size-fits-all, churn-it-out-and-move-on type of installer.

We recently had GreenFlare install an air source heat pump and underfloor heating in our home, and we couldnt be happier with the service and results. The installation was done in phases, and the whole team made sure each stage was seamless. Special thanks to Ash, Callum and Matt, who were fantastic throughout they guided us through every step, helped us prepare, and made sure everything was perfectly set up.
Their customer service was outstanding, and they were incredibly understanding and flexible when we faced construction delays. GreenFlare made what could have been a stressful process smooth and enjoyable. Highly recommend!

Google doesn't have enough stars to properly rate Tom and his team! Working with Green Flare has been an absolute pleasure. It was clear from our first meeting that Tom understood not only his specialist field 'renewable energy', but also houses themselves and how different aspects of their construction came into play. We couldn't be happier with the results.
Not only have i received a great education, but Green Flare has helped us to drag our outdated project home well into the 21st century! On site everyone from Green Flare has been not only professional in their own specialties but also a joy to have on site and work alongside. Special mention to Rob and Kian who not only did their own work faultlessly but then helped me shift a ridiculously heavy 12 x 6 metre sheet of rubber through the house and out the back ready for installation. Without them it'd still be on the drive way. Long and short, don't hesitate to call them. Steve

Green Flare completed the installation of my 19-panel plus 12.4kWH battery and invertor a few weeks ago. It is working brilliantly, with big reductions in my energy consumption already. Tom went through the design of the system with me initially. He's a real expert and he has a system on his own house, so he advises from personal experience so provides much practical advice.
He didn't try to sell me extra bits. For example, a car charger. He advised it was best to wait until I got an electric car, as the charger technology may have improved by then. Joe in the office was extremely helpful, coordinating the installation with my builder's programme. The guys who fitted the system (Clay, Matt, Alex and the team) were extremely collaborative, ultra-helpful and very polite.
They are very professional and were responsive and keen to listen to our comments - even down to changing the colour of some trunking. I am delighted with the service, the quality of the system and the results. Thanks again guys, you have one very happy customer here!

Green Flare were amongst a number of companies we approached for a quotation to provide solar panels to the village hall. The boss, Tom was more than helpful and always available to answer our questions. He has an easy going, knowledgable personality and nothing is too much trouble. His communications skills are excellent and we were able to understand what we wanted and the cost (without VAT!) Green Flare had to bid for the 'grant funded' work but were the cheapest yet most comprehensive bid.
They are also local to the site. They managed the scaffolders and dealt with the integration with the battery, inverter and linking to provide and income from the National Grid. Green Flare did everything and more that we wanted and know they are just a phone call away if we have any queries understanding the App showing what we are generating! Thank you to all at Green Flare!

Green Flare installed a replacement inverter, battery and EPS system to my existing PV system. Work carried out very professionally. Staff very friendly and efficient. Support to help me configure the system as I would like it was also very good. System is working perfectly and saving me money from day one. Overall their quote was the best value of the five we had. We were very pleased with our choice

They made sure everything was working and continued to offer advice and support until I was happy that I knew how to control the system. I have no hesitation in recommending them.

Selecting a solar panel installer is a bit of a minefield - I met several before spotting a Green Flare van in our village an asking for a quote - I had very specific ideas about the sighting and visual impact of my installation and the Green Flare team worked hard to accommodate my requirements - The installation team were helpful and efficient and I am delighted with the finished product.

Greenflare originally came onboard as the heat pump supplier to backup the MVHR unit we were interested in installing. They ended up solving all our problems to do with renewable energy on our project. They managed the entire GSHP instillation including the boreholes, ground floor underfloor heating, cooling linked into the MVHR system, hot water tucked away in the loft and solar including batteries.
In doing so they overcame all the technical challenges of installing such a system in a 1930s semi. Matt and Ollie were great to work with on the GSHP and the guys on the solar just got on and did their job as well. Greenflare really did deliver. Were now living in a zero carbon house having had the gas disconnected, using a green electricity supplier (Octopus) and now that the days are getting longer generating most of the power we use! We are very happy with then service provided by Greenflare.

Moved into a property with a heat pump installed by Green Flare. I am in awe at the way it has been installed and the efficiency of the Mitsubishi pump. Additionally, they are at the end of a phone to speak and advise if like you are long in the tooth and determined to understand the new technology. Visitors to the property are intrigued as to how it all works and seeing a heat pump in situ. Thanks Green Flare

I couldn't be happier with the service provided by Green Flare! From the initial consultation to the final installation of our new solar panels, every step was handled with professionalism and care. The workmen were not only skilled but also friendly, making the whole process a breeze. They took great care to tidy up after themselves, leaving no mess behind.
Our new solar panels are already making a noticeable difference, and I highly recommend Green Flare to anyone considering solar energy solutions. Thank you for a job well done!

I've just had an air source heat pump installed by Green Flare and so far I've been very impressed by its performance, though it is early days. I decided to go for the more expensive option, which offered additional reliability and the possibility of the pump being repaired remotely, as the pump was for a holiday let. Before the pump, heating and hot water were provided by a wood burner with a back boiler, a very labour intensive and not very convenient system.
The team who installed the pump were hard-working, polite and very careful with the fabric of the cottage. I would definitely recommend Green Flare to anyone thinking of installing an air source heat pump.

Excellent and very easy to do business with-an excellent all round good experience from the quotation to the installation (who benefitted from the bacon rolls, tea, coffee and cakes). I was expecting a delayed start due to the very poor weather in the 2 weeks prior to the fitting but they turned up bang on time - brilliant

Very impressed with Green Flare installation which was completed faster than expected. All staff were friendly and thorough. The system is yielding beyond my expectations even with a wsw facing roof. The morning sun from the east is even covering the base load. 6.2kwh even on a dark miserable rainy day and 25.4 so far in April sun so high expectations for the summer. Highly recommended company

We're absolutely delighted with our new solar panel and battery installation by Green Flare. The team integrated the panels into our roof which looks amazing and unobtrusive on our old (unlisted) property. Just two weeks in, the battery system has taken our daily electricity costs down massively even on the dullest day. We're so pleased to have taken the plunge, and would highly recommend Green Flare.

Green Flare recently installed solar panels and battery storage system at our newly renovated home. From the moment they provided us with a quote to the sign off after the install, their professionalism, customer service and attention to detail has been faultless. The job they have done with us has been superb and the implementation team first class. I would not hesitate in recommending them to anyone.

Great company to do business with. No hard sell - just a company that knows what it is doing - which is so reassuring. Solar system bought off the back of 2 recommendations and I am happy to pass on my recommendation to others. Easy to understand how the system works. Importing from the national grid has plummeted!

We've not had it long so can't review the items but our experience with the entire Green Flare team from start to finish was great. From the initial quote, to the follow up information, right through to the installation team - all were professional and polite and did a great job.

I wanted green flare to come down to Cornwall and fit my solar pv panels. I wanted the best. Zak, clay and Tom came and stayed in our annexe and did a perfect, outstanding job. So pleased. The lads were clean, tidy and extremely good workers. The weather in oct 22 was awful for them, high winds and rain on the isolated north coast. The guys had a constant smile. Cant praise green flare enough. 10/10 would highly recommend

Following a recommendation we contacted Tom at Green Flare. The advice was professional, objective with options clearly explained and set out. We appointed Green Flare to install an ASHP and full underfloor heating and hot water system for our barn conversion. Tom and his team were highly professional, worked quickly, carefully and completed the project on schedule. The service received was excellent and I would most definitely use them again. Highly recommended.

I had been thinking about installing a heat pump for a while as our old oil boiler was on its last legs, but I had found it impossible to find an installer who knew what they were talking about. Then I spoke to Tom. He was a revelation, it was clear that he did fully understand the technology and he did not try to sell me anything which would not work in my old house.
I had initially contacted Tom because they deal with Stiebel Eltron but he ended up suggesting a Mitsubishi Ecodan as it was more suitable for our application. He surveyed the site and proposed a system, and then he and Aaron installed it in a matter of weeks. Aaron was prepared to take the time to install it in a way which worked best for us and the quality of his workmanship is superb.
Heat pump systems are more complex than boilers and you need someone who knows what they are doing. The system is working well, it is much quieter than the oil boiler, and it is more controllable. I would recommend GreenFlare whole-heartedly.

We wanted to reduce our carbon footprint and reduce our heating bills. Green Flare replaced a very old oil fired boiler system with an Air Source Heat Pump, also installing some solar panels on the roof. We did this in conjunction with some major insulation works. Result: From a cold and damp house to a warm and dry house saving us nearly 1,000 a year on energy bills. Have run the system through two full winters now and still very satisfied.

Tom helped me through the process of heat incentives available at the time and we worked out a design that we're very happy with and has been incredibly reliable.

I invested in a highly complex solar panel system 10 years ago when I renovated my house, which was installed by another company. Within 2 years it wasn't working properly and the company had gone AWOL. British Gas wouldn't touch it as they said it was too complicated. Tom was recommended by someone locally. He quickly identified the issue and replaced the faulty part with a much better system.
Over the last couple of years, he has saved me hundreds of pounds, as the solar power now generates all of my hot water throughout the summer. Recently, I have had some concerns over the boiler again and he has been quick to offer fixes, even when out-of-hours. Can't recommend highly enough.
