Commercial & Domestic Renewable Energy Specialists

Working alongside GSM Ltd during the heating decarbonisation installation at Tewkesbury Council offices, I was particularly impressed with their effective mobile app /  mobile HSE portal. It provided real-time visibility of on-site safety compliance and ensured that any issues, including potential hazards or near misses were flagged and addressed without delay.

Their innovative approach to health and safety, combined with clear documentation and instant access to RAMS and certifications, set a high benchmark. GSM Ltd demonstrated a proactive safety culture throughout — the streamlined delivery of their documents greatly assisted my delivery as CDM Advisor.

Fantastic service and installation, highly recommended

I was prompted to look at Solar by a local authority “Solar Together” initiative. Having got an “estimate” and outline through that scheme I had my doubts about the costs. I decided to contact local firms and GSM were recommended by a friend.

I have to say I was very impressed with the whole process. Allan Farr was our PM – he came out scoped the installation and provided a detailed quote the same day. GSM were much more competitive than the previous estimate I had and the proposed installation and equipment felt better all round.

Allan was on top of everything throughout and visited after completion to go through all operating instructions and to provide all the necessary documentation to make sure we were happy.

A great experience all round. I would recommend GSM to anyone considering a solar installation – in fact I have many times already!!

Great company , they did a very Fast high quality install from quote to order to up and running solar and battery storage within a month.

Positive experience. Polite and efficient.

Competitive price, excellent workmanship. All members of staff that we dealt with were pleasant, friendly and informative and always took time to explain any issues we were unsure of, from the initial discussions to handover and since. We certainly would not hesitate in recommending GSM to anyone considering installing Solar panels

GSM have demonstrated a consistent ability to design optimal, site-specific solar PV systems that maximise performance while remaining sensitive to the operational and structural limitations of each building. Their team has engaged collaboratively with our supply chain of consultants — particularly on structural assessments — helping to expedite technical approvals and avoid unnecessary delays. Their early engagement with structural engineers and proactiveness in resolving loading queries has streamlined the delivery process considerably.

GSM Ltd have delivered our solar PV projects to a very high standard. They bring strong technical understanding, dependable project management, and a genuine interest in delivering wider value for our district

100% Recommend GSM Solar panels etc efficient, tidy polite workmanship.

Excellent service from start to finish. After being repeatedly let down by other installers I was nervous but the GSM team delivered exactly what I needed when they said they would, quickly and efficiently. The entire Solar system was up and running in less than a day! Very pleased with the install.

From start to finish we have had an excellent experience with this company.
