Jonny and Ryan Work was excellent, very efficient, quick and friendly. Reviewing on behalf of my grandparents, they were great with them and there very happy with service provided From Alnwick

Mr Dave Joyce was the man that came to my house today.He was very professional in all ways possible,explaining everything in great detail of what would happen when heating is installed. He advised us on the best places for the radiators and boiler to be fitted .He was very polite and answered all our questions .in terms we could understand.All round very nice person.

very helpful and very tidy and would have them again/the service was absolutely wonderful

A fantastic experience using GSL from the initial surveys to installation. Very importantly, GSL spent a lot of time talking to us about the solar panel configuration on our roofs as it wasn’t straightforward- we had two surveys & they delivered an excellent proposal which we took forward. During the installation, we had a few ‘hiccups’ but the measure of a good customer-centric company is how well they resolve issues & GSL were excellent! Special mention to Lorraine in the office - her customer service was outstanding! Also thanks to Zoe (office) & Martin (electrician) who also delivered fantastic customer service. I would DEFINITELY recommend GSL 👍

Install went well, installers appear to have done a good job and were very helpful. Unfortunately 2 weeks later scaffolding is still up and I don’t have a date it will be removed and it’s partially blocking the drive. Grant store need to realise this has resulted in a negative review

I recently had an installation completed, and I couldn't be happier with the entire experience! The team was incredibly professional, efficient, and meticulous in their work. The installation was completed in an impressively short time without compromising on quality. Every detail was executed to absolute perfection, showcasing their exceptional craftsmanship and expertise. From start to finish, the process was seamless, and the level of professionalism was truly outstanding. I highly recommend their services to anyone looking for top-quality work done with precision and care!

A really excellent job! We had great support from the office team, Lorraine was brilliant at following up on any questions and generally keeping us informed of progress. The site team, led by Hassan, did a really neat job, completed on time and did a good handover explaining and setting up the App. Thanks

We had 8 panels and a 5kwh battery installed by the Grant Store. The good: -Good value for money for what we had. -Scaffold, panel and electrical installation were all done by different people over a number of days. All the guys I met were friendly and hard working and left the place in a clean condition. Not so good -We were left with virtually no information on how the system runs or what the software was telling us. -Because of the above I wasn't sure if something was wrong when we were exporting all of pur solar generation. -I phoned them to get some help. The people I spoke to on the phone were polite but weren't technical. Every single time I rang, and a had to ring a lot, the technical team were in meetings or on a call. Despite being told they would call me back each time it was only on the fourth day of trying that I actually got a call back (but not from someone technical) to tell me there was in fact a problem and they'd send someone out. At this point, the original electrician came out and fixed the problem with incorrect wiring. He was very apologetic. Overall, I cannot recommend The Grant Store until they improve their aftersales. The software supplied (fox) is not great which isn't Grant Stores fault but it means that people will probably need help understanding what's going on. It's not acceptable to not be able to discuss potential issues. On the positive side, I do now have a working solar setup that will significantly reduce my electricity bills for years to come.

Very good service and tradesmen

First class response from the HQ particularly Zoe who went out of her way to keep us informed, chase up the fitting team and much more. The team that fitted the panels the electrician who made a great job of wiring and connecting everything together. Great work and well done team. We would recommend your company to friends and neighbours. Regards Michael and Janette Brady
