We selected Techfor Energy having looked at a few suppliers as it was clear they knew exactly what they were talking about. The pre-contract survey was incredibly detailed and resulted in the design of the perfect system for what we wanted. They are absolutely not the cheapest solution but we have total confidence the extra cost was a worthwhile investment in system quality, the quality of the installation work and the after-sales support. The selection of Tesla for the battery storage caused us some unexpected delays in delivery but the solar panel installation was very efficient and everything has worked perfectly since day one. Would totally recommend Techfor Energy.

We had a roof array installed as well as a car charger and Tesla battery+dc expansion fitted. The team that came was really friendly and easy to have around. The team at our house and those we communicated with by email ensured regular communication, which was really helpful. We had an issue setting up our export tariff with our energy provider, and Oscar was especially helpful, ensuring we had all we needed to get our tariff set up. The product/apps are great, my techy husband is especially pleased with the end result. 10/10 would recommend.

10 We first considered solar panels in 2015 and having researched on Which Trusted Traders we contacted Glenn Ashby and his team at Techfor Energy, found them very knowledgeable, thorough and indeed impressive. We consulted them again 7 years later when our roof needed retiling and after listening to their advice agreed to their installing further panels, a Tesla battery and myenergi equipment. We are always happy to speak to them to check when we need advice. on any aspect as happened today! Job location: RH4

Installation of solar panels, battery and EV charger

We are very happy with Techfor Energy and their installation of our solar panels, battery, and EV charger. Glenn is evidently very knowledgeable, and during pre-sales calls, he took the time to carefully explain the technical details of the proposed solution, and I really appreciated their scientific approach to picking the panels they supply as a company. The scaffolding was put up/taken down when it was meant to be, and the roofers and electrician were all tidy and polite. Minor issues that arose were handled without fuss. Overall, we are very happy with our system and will gladly recommend Techfor.

It was immediately evident from my first conversation with Glenn that he had vast knowledge in the Green Energy field, unlike some other companies I spoke to. From the first interaction to the final installation and subsequent ongoing support, he was by far the most helpful of all the solar companies I contacted. I had 13 panels & Tesla Powerwall II installed, and I was slightly sceptical as to the savings promised, but I must say it's definitely lived up to what I was told to expect. Currently, I have absolutely no hesitation in recommending Glenn & his company.

We had Techfor replace our current solar array with a bigger one, and fit a Tesla Powerwall battery. Great comms throughout the process, from initial discussion and survey to advice and help on how to switch our FiT deemed export over to a SEG Export tariff - they fully understood all of the complications of having an existing FiT array and could answer any and all questions I threw at them. Install was completed on time by a great friendly crew who did a very neat job. We're really happy with the result - been completely off-grid since the install was completed earlier in the week, and that includes charging our MG4. The quote and cost may have been a little higher than others we had received, but well worth it for the obvious knowledge and experience. For example suggesting we'd be better off replacing our existing garage roof kit with new panels, rather than just adding on a completely new array on top of the house - therefore removing the need for any complicated scaffolding.

Thoroughly recommended for solar panel & battery fitting

We have been very impressed by the service and workmanship provided by Glenn Ashby and his team at Techfor Energy. Glenn is clearly very knowledgeable and experienced in this area. He carried out a thorough survey and explained his suggestions and our options very clearly. The quote was comprehensive and competitive (something to be aware of when comparing with other people for example, one of the competitor’s quotes did not include the cost of scaffolding whereas Glenn’s did). The fitting team were totally professional and unfailingly polite and respectful of us and our property. At the peak of the work they were on the roof and in the loft, kitchen and garage but were still considerate. Since having the system fitted and switching to a suitable tariff, we have used hardly any full-price electricity. In winter, the house battery and car (plug-in hybrid) charged overnight on cheap power; with sunnier days now, the charging mainly happens with solar power. In 2023 & ’24 our electricity cost £168 per month on average for January and February; this year we paid £42 per month for those months. No doubt this will be even better as we move into summer.

Solar panel installation on old tennis court

We wanted to install solar panels on our tennis court which we no longer used rather than on our roof. I spent several months researching a subject I knew little about and spoke to a large number of companies. Techfor Energy stood out as one of the most knowledgeable. We were impressed with their survey and detailed quote which seemed extremely thorough. Now that the work has been completed we are extremely happy with the end result and believe we made the right choice. We are self producing a good percentage of the electricity we consume and with the Tesla batteries are able to store it at off peak rates. There have been one or two teething problems but these have all been resolved so far, and the support has been first class. I would certainly recommend Glenn and his team to anyone who is looking for a quality solar energy installation

Techfor Energy provided an extremely professional, technically excellent and friendly service throughout my project. The project management was excellent. All the tradespeople involved in the installation were polite, very competent and reliable. The workmanship was excellent and the project was completed on time, on budget and without fuss. The technical director was very closely involved throughout and was very impressive with his depth of knowledge and professionalism. All my questions were answered promptly and fully. I would recommend this company without hesitation.

We had solar panels, a new car charger, water heater and batteries installed. Everything was great from the initial scoping of the project and planning all the way through to having scaffolding up and panels installed and subsequent battery installation. The whole team are great, and were a pleasure to have on site. I have recommended now several times and would continue to do so.
