Glow Green

"I chose Glow Green because I trusted their expertise to design the right solar and battery system for my home. Unfortunately, my experience has left me feeling disappointed. From the beginning, I provided information about my household and expected Glow Green to recommend a system that met my long-term energy needs. The system I was sold quickly proved to be undersized, and I have since had to purchase additional battery storage. Glow Green now claims the original design was based on an annual electricity usage of 2,000 kWh. My actual household usage is around 6,500–6,600 kWh per year, and I have asked them to provide evidence of where this figure came from because I do not believe I ever supplied it. The sales process was excellent while I was deciding whether to proceed. Megan was responsive and communication was quick. However, once I had paid my deposit, I felt the level of customer service changed considerably. Emails and phone calls that had previously been answered promptly became much harder to get responses to. The overriding impression I was left with is that securing the sale became the priority. Before I committed, communication was excellent, responses were almost immediate, and I genuinely felt like a valued customer. Once payment had been been made, that changed dramatically. Responses became slower, communication became more difficult, and the level of support I had received during the sales process disappeared. As a result, I was left feeling that the focus had been on winning my business rather than ensuring I received the right system and the level of after-sales service that should accompany an investment of over £9,000. In my experience, customer care appeared to take a back seat once the contract had been signed. The planning stage was particularly frustrating. Morgan, from the planning team, was often difficult to contact, and I received information that I found to be inaccurate or incomplete. This led to unnecessary confusion and delays throughout the installation process. There were also several issues with delivery and scheduling, and I felt I was often left chasing for updates rather than being kept informed. I was also disappointed with the design process. When I raised questions about the layout of the system before installation, I felt my concerns were dismissed and was simply told that the engineer would deal with it on the day. For a purchase of over £9,000, I expected a much more detailed and professional design service. To Glow Green's credit, they did provide a second battery and an additional panel at a discounted price as a gesture of goodwill, which I appreciated. However, I still feel the original system should have been specified correctly from the outset, avoiding the need for further expense. Overall, while the installation itself was completed to a good standard, the communication, planning, design process and after-sales support fell well below the standard I expected. Based on my personal experience, I cannot recommend Glow Green and i have rated there services a 1 star. If you are considering using them, I would strongly encourage you to carefully check the system they are designing before signing any contract, and ensure you are confident that the system genuinely meets your long-term needs as they only care about getting the sale completed."

"We paid tens of thousands of pounds to have a heat pump and solar PV installed by Glow Green. The solar installation was fine. The heat pump installation was one of the worst experiences of my life. Following the heat pump installation we were left with a large hole in our kitchen wall for three weeks where the old boiler had been removed, exposed electrical cables accessible to our young children, raw copper pipes left protruding from walls and floors, a damaged loft hatch that had to be replaced entirely, and extensive damage to our front lawn. Much of the resulting damage I had to repair myself, at my own time and expense. On top of this, the heat pump itself could not sustain a single shower — the water ran cold within minutes. These are not snags. These are serious failures that left our home in an unsafe, unfinished, and barely functional state for weeks. Getting any response from Glow Green required months of chasing. Emails went unanswered for weeks. Phone calls were not returned. Appointments were made and not kept, repeatedly, with no warning or explanation. Issues were passed between departments with no ownership. Eventually everything had to be escalated to CEO level just to get a response. A senior member of Glow Green's team verbally acknowledged during a site visit that the installation had not been handled properly. Glow Green subsequently opened a formal complaints process — and then closed it without resolution or explanation, apparently on the basis that one of many outstanding issues had been partially addressed nine weeks after installation. Despite everything described above, Glow Green have not offered a single penny in compensation or reimbursement. We have photographic evidence, Ring camera footage, and a full correspondence trail supporting everything stated here. Do not use this company."

"Look at the workmanship, impressive to make it look so awful, used the existing gate bracket which at some point will rot, they have drilled some massive screws into the wall. I wasn't asked about this, nor was I made aware that I would have pipes running outside rather than do it properly and go internally. Honestly, please avoid, pay a bit more and use the like of British Gas or a recommended independent who will value the work they put out. In addition to the work being terrible, this was after 3 or 4 days of being messed around regarding fitting. As above, please consider using someone else!!!"

"Recent heat pump Installation Absolutely disappointed with the service received from Glow Green. Since the installation, trying to get proper technical support has been extremely frustrating. Repeated promises of callbacks from the technical team were never followed through, despite chasing multiple times over several weeks. Repeatedly getting E912 errors… No control from Hive meter. Heating system shut downs after 10-15 minutes. Extremely cold at night. Customer service has been poor, communication has been inconsistent, and genuine concerns have not been handled professionally. It feels like there is very little accountability once the installation is completed. If I had known in advance that this would be the level of service and aftercare provided, I would never in a million years have chosen to proceed with this service. I expected much better support and professionalism. Unfortunately, this has been one of the worst customer service experiences I have dealt with."

"Smooth, Professional Service from Start to Finish I had a great experience with Glow Green from start to finish. Everything went smoothly, and the whole process was very well managed. I dealt with Ashley from the beginning — he was really helpful, answered all my questions clearly, and provided a quotation without being pushy at all. He was easy to communicate with, which made a big difference. On top of that, the price was very competitive for the boiler I had installed. Ashley also organised everything seamlessly. The installation team were spot on — they called ahead, kept me informed, and let me know once everything was completed. I also received a final call from customer relations to make sure I was happy with everything. Overall, the whole journey made me feel valued as a customer. I would definitely recommend Glow Green"
