I am in the sales industry myself and am regularly left disappointed by companies I employ but I have to say that Glenn Ashby and his team have been absolutely superb from the very first meeting up to completion of my new solar system. His team also upgraded my loft insulation and installed LED lighting all done efficiently and without any hassle whatsoever. I am a very happy customer how has no hesitation recommending Techfor Energy 100%.

TechforEnergy installed a 2.4KWp system for us 9 months ago: 8 x 300W LG panels with micro inverters ??" 7 panels on the main roof of a mid-terrace house and one on a ground floor bathroom roof to maximise generation. I chose TechforEnergy because their communication skills were second to none. We had 2 other quotes (all WhichLocal recommendations) but Glenn Ashby was always on the end of the phone and happy to return calls. The company are professional and experts in their field ??" not just Glenn who carried out the survey, but John Appleby providing support from the office. Surprisingly too, TechforEnergy???s quote was the cheapest of the three. At no point did I feel rushed or pressurised. Glenn took as long as was necessary to answer all my questions and talk through alternatives. I felt confident at all times that he would recommend what was best for our situation because he wanted to provide a first class installation (which he has) and obviously appreciates the importance of safeguarding his well-earned reputation. I was particularly impressed by a previous review on Which that he had told one prospective customer that it would not be financially worth their while to install panels. So obviously honest. On the day, the system took just 2 hours to install on the roof (we had a very simple cable run). That included the time it took to go to a nearby builders??? merchant to replace a broken roof tile for us at no cost. You couldn???t ask for more. The guys who did the installation were professional, efficient, respectful, clean, tidy and friendly. It???s worth knowing too that TechforEnergy will reward their customers for any recommendations you make that result in an installation ??" I have a friend who has used them and they are also suitably impressed. If you are still wondering whether to install solar or not, I wouldn???t hesitate to recommend that you get TechForEnergy to carry out a survey for you. Quite apart from reducing carbon emissions, financial returns surpass anything you could get from a savings account at the moment. And installing a solar array guarantees an income, so it???s not got the associated risks of other investments. It???s worth bearing in mind that you need to use as much of the energy you generate as possible before you export to the grid to maximise savings. The predicted financial returns in your quote will be based on assumptions e.g. ours was based on being able to use 5?6kWh per day from our PV system (about one washing machine load). So behavioural change is key ??" you need to use energy when the sun is shining to maximise savings or set devices to run during peak production hours using timers if you are happy to do so. But any assumptions are stated in the quote you receive. The online ???Enphase??? monitoring system we have also tracks how each of our panels is performing ??" be warned for the first few months it???s addictive! You can sit in the office, find out the sun was shining, and wish you???d set the washing machine before you???d left the house. You will have access to daily, weekly, monthly and lifetime reports. It???s also telling me that last month we offset 3 trees worth of carbon. (Be warned, you may need to guard against being too self-righteous down the pub). Finally, with the cuts to FIT that the government is planning, now is the time to do it ??" don???t delay. The Government is proposing reducing the FIT to 1.6p from January 2016. Please sign the petition at: http://tinyurl.com/nqpelsg. TechforEnergy???s home page also has a link to it. Regrets? Only that we don???t have a bigger roof... [As an aside to this review, the solar trade industry estimates that 27,000 jobs are at immediate risk due to the proposed 87% cut to the domestic feed-in tariff and the government admits that ???carbon emissions will increase??ù as a result of the planned changes. People providing the kind of service TechforEnergy provide deserve to stay in the job].

Glenn Ashby spent a long time considering all our options and was careful to find out what we hoped to achieve from the system, both long and short term. As a result the final system was designed to suit us, not the installation team. Communications with the office before installation were excellent. The installation team was careful and kept disruption to a minimum. When contacted regarding minor issues after installation, the company was just as attentive and helpful and quickly sorted them out.

Glenn is extremely knowledgable and experienced which made the decision about choosing the company easy. The work was completed to an excellent standard during severe weather conditions of hard frost with sub-zero temperatures followed by persistent rain. Glenn's team of Michael and Wojciech worked extremely hard to keep the job on time without complaint. Harsh the electrician worked well beyond his hours to ensure a tidy installation and that the whole system was working correctly. I have no hesitation recommending Glenn and his excellent company.

Vanishing electricity cost

I am the delighted owner of a 6kw PV array and a Tesla battery. Our roof is SW facing and we have lots of tall trees nearby. We had lived in a grade 2* listed house for 46 years where PV panels are forbidden. On moving we chose Techfor Energy as Glenn told sensible facts, treated me as a colleague and did not try to force us into a deal. The panels were installed in December 2018 and the battery in May 2019. The battery has stopped us needing to use the mains and allows us to do the washing and tumble drying at times to suit. In winter the panels and battery will considerably reduce our reliance on the mains electricity – we will use Agile Octopus to charge the battery when rates are low. Software is supplied to enable me to monitor the panels and battery. Before the Powerwall we were exporting often more electricity than we were using from the mains. I have been extremely impressed with the standard of workmanship and communications from the company.

We chose this company on the basis of excellent Which? Trusted Trader reviews, and we have not been disappointed. It was very quickly evident that this company knew what they were talking about in a way that went far beyond other companies we approached, and were willing to take time to explain clearly what the options were, without any high pressure sales techniques. They did what they said they would do, when they said they would do it, and to a high standard, and so far (it's early days) the solar panels and battery storage system have been producing in line with Techfor's predictions. When we ordered the storage battery we were informed of a waiting list to receive these, but in the event it was fitted sooner than that. We had some technical issues with our electricity company over getting a smart meter installed, and Glenn at Techfor tireless, and an enormous help in sorting this out. I cannot recommend Techfor too highly.

I was recommended to them by another of their customers. The consultation and review of how we could obtain best results was very thorough. We also had loft conversion at same time, both tradesmen consulted each other ensuring Windows placed in optimum positions to gain maximum numbers of panels. Communication throughout was thorough and informative. All the tradesmen on site were very polite and obviously very knowledgable and experienced in the areas they were working.

Supply and install solar panels and storage battery
It was very clear from the time that our three bids for solar panels where received that Techfor Energy were offering the best technical advice about our specific needs and the quality of their bid. All three bidders were selected by having high check-a-trade scores, but Techfor stood out amongst the others. They were the only ones to do a structural survey during the first home visit. They were the only ones to suggest we consider installing an energy storage battery. I am so pleased we went with Techfor. The installation was in two phases, the first for the solar panels, the second, some months later, for a Tesla Powerwall storage battery. Both went well, with Techfor even rectifying a previously unknown sealing problem with one of our roof sky-lights. They listened to what we wanted and tailored their bid to meet our specific needs (e.g. control boxes and battery on the unused east side of our house, despite the electricity meter being, and main thoroughfare, on the west side of the house). The software that comes with the systems is fantastic. Every time the sun shines, I am glued to the apps looking how well the system is doing. I can even keep track of what the Children are doing (electrical usage wise) while we are miles away from home. I am really pleased with the system we went for, and really pleased with the way Techfor supplied, installed and commissioned the systems. Highly recommended.

We contacted 3 suppliers to get information & quote. Two of the responses were laughable. The Techfor response was a very informative call lasting 45 minutes from Glenn Ashby who demonstrated an interest in the requirement and provided information in a easy to understand way. Very professional. This was followed by a paid site visit (at reasonable cost and knocked off final bill) that resulted in an extremely detailed quotation covering solar panel and Powerwall installation. Questions arising from this were swiftly dealt with by Glenn. Very professional. With the quote accepted, installation date was agreed. Scaffolding was erected by the Techfor chosen partner and then the Techfor team turned up to install the solar panels and supporting electrical installation. This team worked with little fuss and carried out the difficult installation (slate roof with all the challenges of lifting substantial areas of slate to accommodate the roof mounting). This took 3 1/2 days to complete which Glenn had warned about and costed in so no unforeseen charges arising. All the work was completed with great professionalism by a very friendly team of guys. The end result is a very successful installation that is producing what was forecast. Glenn provided very useful information to get the most of energy supply and export tariffs. We are still waiting on the Powerwall which is on long lead time but Techfor are keeping us informed of expected delivery timescale. Overall - brilliant!

Techfor installed PV panels in 2016. Additional PV and Tesla battery installed operational from 21/7. What a difference. Very little grid power since then and only at night if battery goes to its minimum setting. System has incredible technology managing house demand between panels and battery. Techfor are a thoroughly professional organisation headed by a very knowledgeable leader, courteous fitters/electricians always keep the workplace clean. We got more than Techfor said we would get from our installation. This is a big investment we are making so choose the best. Techfor

Really helpful advice, not pushy, genuine chap
Spoke to Glenn looking for a solar thermal quote. His first reaction was that for our needs, supplementing our existing PV solution would be a better long term investment (about the same cost but far lower ongoing maintenance costs). He advised that we were outside of his area, but rather than just saying bye, he then took the time to walk me through a number of options for panels, pros and cons, installation sites (including the fitting to use) and options for expanding the system in the future with a battery, to use as a basis for talking with more local installers. It is not often you come across someone as genuinely helpful these days.

The team did a wonderful job installing a brand new system comprising forty solar panels which were spread across two roofs. The original survey was very thorough and he spent some time discussing our needs and how best to accommodate them. The installation went ahead as scheduled and completed a day earlier than forecast. His team were a delight to have on site, being efficient, courteous, tidy and helpful. I would have no hesitation in recommending Techfor Energy to anyone considering installing a Solar PV system.

Tech4 Energy originally initially installed our Solar PV, Tesla Powerwall II battery and myenergi equipment. They did a fantastic job and the system has been in operation for 3 years now. HOWEVER, we made the mistake of going with a 3rd party supplier (major UK "green" electrical supplier) to install a Zappi EV charger. BIGGEST MISTAKE EVER. The engineers from the 3rd party company were not trained, did not understand how to integrate the Zappi charger into our (myenergi) installation, violated Heath & Safety and electrical compliance standards. PLEASE DON'T MAKE MY MISTAKE, USE SOMEONE LIKE TECH4 ENERGY.

8 solar panels, 1 Tesla battery, 1 car charger

At the end of 2023 Techfor Energy installed 8 additional solar panels, a Tesla battery and a car charger at our property. Initially, I was mostly interested in a battery, but Glenn pointed out that I had space on a SE facing roof which could take additional solar panels to make us even more grid independent. I was very reluctant to let anyone onto our new roof, having had a bad experience with the company which installed the first solar array. However, Genn told me how meticulously he trains his roofers and how he ensures that nothing is damaged in the process. His team o scaffolders, roofers and electricians were very competent, polite and left the sites (roof, garage, driveway) spotless. Almost a year later, I am happy to report that we have been 100% self-powered (Tesla speak for not using any electricity from the grid, etc.) between the 17th of March and the 7th of September this year. Even in gloomy January we were 45% self-powered. Besides feeling smug about saving the planet and being grid independent, I am sure that electricity prices will inevitably go up even more to pay for the energy transition (increasing capacity of the grid) and that blackouts might become more common once net-zero forces everyone onto the grid. I highly recommend Techfor Energy and appreciate Glenn’s continued advice regarding most cost-efficient tariffs.

MY JOURNEY INTO SOLAR POWER! Best thing I ever did was phoning Tech4energy and speaking with the owner, Glenn. I made an initial appointment and Glenn visited promptly and carried out a full survey of my home’s potential for Solar Panels. The survey was extremely comprehensive and the following week I received a very detailed report with options and the relevant costings. At no time did I feel pressured to adhere to Glenn’s advice but I am happy I took it. Day of installation arrived and everything went extremely smoothly and to plan. The guys installing were extremely neat and tidy and everything was completely cleared up at the end of each day. On the 3rd day in the afternoon the Solar Panels went Live I had a battery installed and Electric Vehicle charger. These were suggested by Glenn and have proved to be invaluable. The battery stores up power during the day and I am running my home on Solar power. I have purchased an electric vehicle and a full charge costs approximately £7.50. I’m also now using my Tumble Dryer regularly - previously a once in a blue moon luxury. I cannot thank Glenn and his Company enough for the quality of my installation. My electric bill is now minimal and I am no longer afraid to use my electric appliances. My quality of life is so much improved and I just wish I’d switched to Solar Power sooner. If you are hesitant to install Solar Panels be assured it’s a win-win decision with this company I haven’t looked back Thank you Tech4Energy

Glenn and his team installed and upgraded a full, bespoke solar panel power system for us and we are delighted with the results. Of the four companies only Techfor carried out a full survey and discussed a bespoke installation for us. This was carried out in three stages: solar panel installation; a Tesla storage battery; and, most recently, an upgrade to the Tesla battery system that allows us to operate as an "island" in the event of a power cut. The work was carried out expertly by the polite and thoughtful Techfor team and annually provides two-thirds of all our electricity needs.
