GSM Limited

Can't praise the team enough for the Solar / Battery install they completed for me in January 24. Had 16 panels, 5kW inverter and 9.5kW battery from GivEnergy installed. Team are knowledgeable and professional, throughout the installation everything was clean and tidy. The routing of all the cables is very smart, being mid terrace I didn't want to see the cable routes, the team was able to sort this out. Both the Electrician and Roofer were diligent, from making sure that the panels were centred on the property to the location of the inverter and battery to ensure the optimal position. Actively considering having the team back to replace the gas boiler with a heat pump.

Shane and his team are amazing and have done a very professional and excellent job. Have had a 8.5kw system with a battery pack installed and additional cabling to future proof it. They are always on hand to explain the workings of the system and make adjustments if required. Highly recommended

A 3.2kW system installed on a raised seam metal roof on a stone built out-building. Eight JA 400w black panels tilted at 30 degrees are wired as two strings on four panels. The Solax inverter and 5kWh battery are installed in the room below. A pre-existing underground 4mm SWA cable and a CAT5 Ethernet cable connect back to the house metering. Note the spacing between the two rows of panels and the use of half cell panels to minimise shading in the winter months. We were able to discuss with GSM ahead of the installation in order to provide a solution and equipment that met our requirements. All professionally installed easily within 2 days. There was a short wait for the triangular mounts. As a heavy user with an EV car and electric AGA, the battery storage on a sunny day provides most of the power used in the afternoon and into the night. We do not export very much but our off grid consumption is noticeably reduced. I can only award 4 1/2 stars as the handover document contains several errors which do not accurately reflect the equipment and system finally installed since the initial quotation. Could do better!

After being let down by another company, I contacted GSM for solar and battery storage installation at my home. From the outset, it was clear they were far superior. They responded quickly, conducted a site visit within days, and worked closely with me to find the most suitable and efficient solution. They handled all the paperwork, installed everything swiftly, and accommodated my schedule seamlessly. Every team member was polite, friendly, and a true credit to the company—special thanks to Richard and Allen. From start to finish, GSM has been outstanding, and we are now mostly off-grid. Thank you!

I recently had solar panels installed by GSM, and the experience was fantastic. The team was professional, efficient, and explained everything clearly. The installation was quick, and I’ve already started seeing savings on my energy bills. I’m really happy with the results and would highly recommend GSM to anyone looking to switch to solar!

The courtesy of a reply to simply say not interested in our project, would have been nice

GSM Limited : Solar energy company in Newent, Gloucestershire England Renewable Energy Installers GSM came out quite promptly within a week and reviewed my ground pump issue. The chap was pleasant and seemed knowledgeable about heat pumps. Realisation and hindsight is that it’s easy to talk the talk…. and you should realise when a company asks you to pay for a service they are going to provide in advance, that perhaps they are not too confident they do actually know what they are doing. If you are reading this you are probably screaming no you didn’t pay in advance, school boy error. But apparently it was their policy to take payment upfront and honestly he seemed a nice guy, plus it was a reputable local company, I see there vans around all the time in Newent and the Forest of Dean area what could go wrong … So yes I paid up front. It then took weeks to order the part we were advise would probably solve the issue, sadly once it was installed you guessed it, this failed to fix the problem. After extensive discussions about how to actually resolve the issue, this company GSM Renewable Energy Specialists of Newent Gloucestershire simply disappeared without a word never came back to me and never heard from them again. Absolutely baffling and quite bizarre really. Complete radio silence. Strange way to run a business in 2025 when customers have a voice and global reach. But I guess plenty of people are switching to heat pumps and as the chap said they would much rather fit new installations than work on ones that go wrong it was more profitable. Eventually having realised GSM Limited Newent simply were not going to return my calls or come back to me, I had to call in a larger more professional company, Hewers based in Gloucester, black and red vans, you can’t miss them, they are all over the pace. Not only can these guys talk all the same talk as others, but have the financial resource, meaning I didn’t have to pay in advance and knowledgeable people to follow through, walking the walk. Hewers resolved my issue, it wasn’t cheap, nothing seems to be in renewable energy, but peace of mind has to come before cost sometimes… not sure where these GSM guys went, 3 months later they are not going to ring me back… are they even still in business ? In conclusion, I have a nice new multi timer for ground source heat pumps fitted by GSM Newent that I didn’t and still don’t need, Hewers said they would remove it and throw it away, it became quite a source of amusement whilst they carried out their work. Whilst It’s no longer connected, I requested they leave it on the wall, it gives me a little smile every time I look at it … lesson learnt …perhaps for all stakeholders in this review, I tell everyone of my heat pump experience and why size does matter.
