TJS Solar is named as the installer across a wide range of solar and battery jobs. One reviewer reports significant problems: a design that fell from 36 panels to 29, communication dropping off after the deposit, staff arriving hours late, and handover documents with wrong system sizes and a non-existent fourth string, with corrections only made after the reviewer spotted them. That reviewer also says the handover documentation and MCS certificates were held back until final payment, and that the complaint had still not been resolved after months. Many other reviewers describe the installation teams as polite, tidy and informative, and say they kept them updated through the work. One reviewer says the scaffolding company was unhelpful and the scaffolding was still up 10 days after installation.
Significant issues with system size, documentation and aftercare I engaged TJS Solar for a residential solar and battery installation in early 2026. The original design and quotation were for 36 panels. When other installers raised doubts about whether 36 panels would fit, I was reassured by TJS that they would “prove them wrong.” In the end only 29 panels could be installed. After the deposit was paid, communication dropped off noticeably. On delivery day TJS staff arrived many hours late with little prior notice, and I had to help unload the panels myself. The final invoice correctly applied a contractual reduction for the missing panels. The bigger ongoing problem has been the official MCS handover documentation. Multiple versions of the handover pack contained clear errors, including incorrect system size figures and a phantom fourth string in the commissioning reports (when only three strings exist). The Single Line Diagram still did not properly show the Sigen Gateway that provides the backup/island capability I specifically requested. Corrections were only made after I repeatedly identified the problems myself. The handover pack and MCS certificates were also withheld until the final payment had been made. I have spent many months trying to resolve these issues through direct contact with TJS, then via MCS and later through Green Homes Dispute Resolution / RECC. Progress has been slow and the matter remains unresolved at the time of writing. The roofers who attended were professional and helpful. However, the overall experience with sales assurances, post-deposit communication, documentation accuracy, and complaint handling has been poor. Prospective customers should carefully check the detail of any quotation, ask for written confirmation of what will be delivered, and be prepared to scrutinise the handover pack thoroughly.
The installation teams of Mike and Warren did a really great professional job and the standard of equipment installed is excellent.
Tony came out to complete the survey and answered all of our questions. TJS were recommended via a neighbour whose friend had used them. We were happy to go with a recommendation and also supporting a local company was important to us. The workmen who came to complete the installation were great - really polite, informative and respectful. They worked neatly and cleanly and tidied up after themselves. The system was installed and Ryan checked it was functioning correctly, showed us the SIGEN app and answered any questions. We would recommend TJS without hesitation. Our only frustration is with the Scaffolding Company who, despite us explaining we were going away on holiday and really wanted it removed before in order to access our garage, were very unhelpful and 10 days after installation, 5 days after we left for our holiday, still have not taken it away. I would advise TJS to consider this when engaging a scaffold company as it could unfairly reflect negatively on them.
Initial consultation was in-person and everything about configuring the system, how it would be built and payments to be made were explained in understandable language. Installation was quick and efficient and the system is now humming away nicely
Very efficient installation and excellent back up by all staff involved. Pleasant and kind workmen.
Great experience from start to finish. Couldn’t be happier with the system installed. Highly recommend TJS solar.
TJS Solar was one of several companies I contacted for a quote for solar and battery storage solution. However, they were the only one willing to make the 1.5hr journey to my property for the consultation, with competitors choosing to do it via MS teams. Stephen was knowledgeable. explained what system he thought would work for me, gave me a price, left his details and offered no more hard sell tactics. Throughout the installation, the workmen on sight were friendly and explained each stage of the install, with Dan in the office in contact to arrange each step. I asked for an additional panel mid way through which they sources and fitted with no issue. Tony took care of the application to the grid which was painless and the system was up and running, generating electricity within 6 hours of them arriving. All in all, highly recommended. I was dubious with who to choose due to all the unscrupulous solar installers, but I can confirm no such issues, and all paperwork was professionally produced and sent to me within a day of the job being finished.
TJS installed a 22 panels system for me with 11.5kw battery and 8kw inverter. Completed the work as promised and had been very responsive throughout the process. I found them technically skillful in the job. Post installation survay of the roof and repairs been the top notch. System is working above expection currently.
After a shaky start (not really their fault - scaffolding being cancelled at the last minute and equipment doing the same a couple of days later), the TLS team stepped up and worked like Trojans in some horrific weather conditions. The install looks excellent, works well (chucking out 5.5kW as I type) and batteries filling up nicely. The paperwork (albeit very complex) is reassuringly comprehensive. Very happy at this stage (1 month after install).
very good service
TJS SOLAR From start to finish were very professional and did an excellent job, it would wrong of me to choose an individual team because they were all very good. Well done boys and many thanks
Excellent work completed as predicted Ryan Rob & Tyler done a good job, I would recommend TJS Solar on price and workmanship 100% 🏴
Professional, prompt, friendly and courteous, you made the whole process smooth, questions answered and everything explained carefully. After installation queries similarly answered. Would recommend this company unreservedly
Prompt team with good work done.
I’m very impressed with the service provided by TJS Solar. Tony was transparent and never pushy, giving me honest information about costs, savings, and timelines. The whole process was quick and completely stress-free — it took just one month from the initial survey to having a full solar system installed. The customer service, workmanship, and professionalism of the team exceeded my expectations, and I can confidently recommend TJS Solar to anyone looking for a reliable solar installation.
I selected TJS Solar as they are Which recommended. Absolutely no regrets. Excellent to deal with from start to finish and excellent after sales service too. We got quotes from a couple of national installers, but were most impressed by Tony on TJS Solars offering. We opted for a Sigenstor and solar solution. Kept informed of DNO progress by Dan and booked in the job soon after approval. The team on the job were great and easy to get along with. Very pleased with the finished job. Since install Tony has offered help to quickly resolve a system issue. Highly recommend.
We had a really good experience with TJS Solar. The work was completed to a high standard and everything was finished neatly and on time. The presentation showing how the panels and battery would perform and benefit us was a big factor in choosing this company. There were a few issues along the way, but Tony handled them promptly and kept us updated throughout. They were also very responsive to all the questions we had along the way. Overall, great service — would definitely recommend!
TJS have installed my solar and battery system which I am very happy with. Their surveyor Garry was brilliant in answering all my questions and being very flexible in addressing my needs. Tony who oversaw the installation is also great. The installation process wasn't smooth, as to be expected, however what makes TJS Solar outstanding is how proactive Tony and the team were in promptly addressing any issues or challenges that I brought to their attention. Their pricing is very competitive, and as they are a growing company customer gets personalised approach (I hope this continues as they continue to grow). So overall I would use them again and would recommend them to whoever is looking for solar installation.
From start to finish TJS Solar were there with us, I fully recommed their service and acvice
Scaffolding up, panels and battery fitted and all commissioned in a week with very little disruption to us. I had to clear the patio for the scaffold to be put up, and make glasses of juice/ cups of tea as it was a hot week! I would highly recommend TJS who were professional throughout and have provided a brilliant Sigenergy system which is already working well
I got a few quotes for solar panels. But by far the most professional was from Tony at TJS Solar. He took the time to listen to what I wanted being a high user and then quoted for a system that would deliver what I needed. He explained all the technical jargon and how it all worked. I could see that he was passionate about his company and the job they do. Tony kept me informed at every step of the way about what was happening. His team were polite and worked in an efficient and tidy manner to get the job done. I’ve now had the system for nearly 2 months and it’s exceeded my expectations in helping me reduce my energy costs and I’m on track to payback my investment in 6-7 years. If you are looking to get solar energy, then look no further than Tony at TJS Solar.
Tony and team installed solar and battery system on our Manchester terrace. The site team were efficient and friendly and explained what they were doing at all stages. Very pleased with our system.
A great experience from beginning to end. Scaffolding up system installed and scaffolding down with a week. Tony kept us informed every step of the way and we're highly impressed with the completed install. We are now, in mid-August selling more energy back to Octopus than we are using which is fantastic. Would ( and have already) recommend TJS to friends as you cannot fail to be impressed with the system they have installed
We recently had solar panels and storage fitted by Tony and his team at TJS Solar. From start to finish the process was easy and well explained by Gary who did the quote to Tony who was always available to answer questions. The cost was very competitive and the install was completed to a very high standard within a couple of days. Would not hesitate to recommend.
The job was done efficiently and promptly once we had obtained the appropriate permit
Just had Solar system installed by TJS. Great service from Tony from first point of contact on our survey where he actually listened to our needs and customised a system to fit. He always made sure he kept in contact with us and kept us well informed through and after the installation. Can't fault the various teams either (scaffolders, roofers, sparkies), always made sure they respected the property and done all work swiftly with minimum disruption. All in all a great experience and every chance we will have we will 100% recommend TJS Solar. Thank you Tony & team!
Cannot recommend highly enough professional service from start to finish and very helpful
Good service with a very competitive price!
Great service both before, during and after instillation. TJS was the only company we got quotes from who put in the effort to fully map out the property with a drone to ensure they could maximise the efficiency of the space. Great communication at all times, friendly team, and the installation was quick. Would recommend to anyone considering solar panels.
TJS have just commissioned our Fox ESS PV system, it's great. Tony and his team really could not have improved on the whole experience end to end. Outstanding experience. Thanks
From start to finish TJS were amazing. It was clear they know what they are doing and answered all my solar questions. Install was done in 1 day, with a friendly team to do it. They have guided me through the whole process to switch tariffs also. Customer service is flawless. Honestly you won’t find a more friendly, trustworthy solar installer.
I'm delighted with my new solar and battery solution. The team at TJS were professional and knowledgeable from start to finish. I recommend you get a quote and see what you could be saving by going solar.
Very fast install very polite and experienced workers looks very smart on the roof not had long enough to say how well there running
I was pleased with the professionalism and great customer service provided by TJS. I felt well looked-after throughout the process of inspection, technical advice and installation. Post installation support was excellent. Furthermore TJS is registered with regulatory RECC, providing extra peace of mind. I will recommend TJS.
Had some 3-phase Puredrive batteries installed on my commercial site, will 150% recommend this company, professional, highly specialised and really good price for install!
TJS is probably one of the best installers I've spoken to in my field, I work with highly technical 3-phase installers and speaking with Ola/ Tony is always a pleasure when dealing with bespoke HV specifications. Heard recently they have become Duracell Energy platinum partners - well deserved!
Highly recommend TJS Solar - Tony is a great guy to work with
I worked with TJS Solar to install a 78KW roof mounted solar system using solar edge optimisers and inverters at Lappett Lancaster. Tony and his team did an excellent Job in an efficient timescale that included the edge protection of the roof, the full electrical installation and the roof PV system. I can confidently recommend them.
