Review for Daniel – Radiator Leak Repair
Daniel visited today to fix a radiator leak and delivered excellent service from start to finish. He took the time to make sure everything was working perfectly before leaving and genuinely felt like he had ticked every box. This was a courtesy goodwill call‑out that the team didn’t have to attend, so I’m especially appreciative of the outstanding customer service. Thank you for going above and beyond.

If it’s solar these are the go-to guys
If it’s anything solar these are the ‘ go to ‘ guys nothing was too much. from the original contact to ronnie the surveyor to the installers the office staff and the accounts department they are all superb the install went without a hitch scaffolding was put up Friday the install was done Tuesday the install was done before 1pm that’s 16 panels an inverter and a battery
The one thing I did notice that grant store actually care they actually want to help you get your system installed. The big box companies like edf ,boxt, octopus all give quotes that are drastically more for less kit ie smaller batteries and less panels and then don’t even call you back
My system has been installed 3 weeks now and it’s amazing how much extra I am generating
You don’t have to look any further
Thanks for all your help guys

Professional Team, Quality Work & Bespoke Solution which caused Logistical Delays - Highly Recommend
Overall, we are very happy with the final solar installation from Grant Solar. The team were professional, courteous and accommodating throughout, particularly Martyn (Electrical Engineer) and David the surveyor.
We had several bespoke requirements including underground routing of the armoured cables into the garage instead of external trunking, plus specific positioning of the inverter and battery system to maximise garage space. The team listened carefully and delivered exactly what we requested.
The installation quality itself was very good and the final system looks clean and professional both internally and externally. David also returned after installation to inspect and verify the works, which was appreciated.
The reason for 4 rather than 5 stars was mainly due to project delays and coordination issues. The installation was delayed by around two weeks because of a lost/delayed armoured cable delivery, and there was also an issue where the Tigo optimisers had initially not been installed, requiring panels to be removed and reinstalled which added further delay. Communication regarding programme dates and scaffold removal could also have been clearer at times.
There was also some minor surface damage around the garage cable penetrations and a few finishing details identified during inspection, although these were relatively small compared to the overall job.
Despite the delays, the installers themselves were excellent and the final outcome met our expectations. I would still recommend Grant Solar overall.

Awful experience, do not use them
Awful experience. They installed solar panels and an air source heat pump. They rushed the job, cutting corners and requiring multiple visits to correct poor workmanship. No care was taken during the installation and they left a trail of destruction behind them. It has been a really stressful experience having had them install these items. I am still having to sort issues out following their work and revisits to try and resolve the problems.

Air Source Heat pump Installation
I had Grant solar install an Air Source Heat Pump back in January. I’m really happy with the outcome the guys came up to Cumbria and installed the system with precision, efficiency and little to no mess. Chris the installation manager was brilliant, he kept us up to date with any issues and gave us great advice and solutions. since having the heat pump installed it has transformed our home into a lovely warm home and has knocked £100’s off our bills. We did have an issue with the hot water but I contacted the team and they were very quick to identify the issue and send some to resolve it. A special mention to John who came and inspected our system after installation. He talked through how to use the system and how to set it up to suit us. He showcased great knowledge and confidence in what he was doing. He also did a great job fixing our hot water system. In January, I had Grant Solar install an Air Source Heat Pump. I’m delighted with the result. The team arrived in Cumbria, installed the system with precision efficiency and minimal disruption. Chris, the installation manager, was fantastic.

We did encounter a hot water issue but the team quickly identified and resolved it. A special shout-out to John, who inspected our system after installation. He expertly demonstrated how to use and configure the system to suit our needs. His knowledge and confidence were evident. He also expertly fixed our hot water system.

I had problems with the Foxcloud app
I had problems with the Foxcloud app, when it was upgraded without warning the reading on the app disappeared. I tried contacting Foxcloud via email but all I got is a Key number, several in fact and in reply to my message to them I got a reply in Spanish which was useless. Having contacted Grant Store I won't mention his name but he sent me an email with an attachment to watch a video and follow the instructions to get the app working properly. That failed. The next day I telephoned again and this time I got through to a lovely lady Katie Chee? She was so helpful, see talked me through the video again and the ask my to WhatsApp screenshots of what was happening, after several screenshots she said she would get back to me soon and she did, there was obviously an issue that needed someone to come out and fix. A week later three young men turned up and after the main Man scratching his head for a few minutes he found out that my address had disappeared on there list, so he promptly created the address again and it's working fine. A big faff but thanks to Katie and the rest of the team its sorted.

Thank you so much for taking the time to share your detailed feedback with us. We truly appreciate your patience and understanding throughout what sounds like a frustrating experience with the Foxcloud app upgrade.
We’re sorry to hear about the initial difficulties you faced, particularly with the lack of clear communication and the challenges in getting support through Foxcloud directly. We understand how inconvenient it must have been to lose access to your readings and not receive helpful responses.
