Phase Energy SE Ltd

I was recommended Phase Energy from a colleague who had his system installed by them and I'm really pleased i was. The process was stress free from the initial contact to installation. Great work from the Phase team.

The team at Phase Energy provided an excellent service and delivered the system on time and it has operated flawlessly for the last year. Other electricians have even commented on the quality of their electric work on the system. I would recommend them without hesitation.

Fantastic experience with Phase Energy. From the initial enquiry through to completion, the team were friendly, professional and really helpful. They kept us informed throughout and did a great job. Very happy with the service and would happily recommend them 😊

I am very pleased with my solar and battery installation. The service from start to finish was excellent, the customer support was consistently responsive and helpful. The installation team were outstanding - efficient and tidy and completed the entire job in a day. The overall cost was very competitive and cost-efficient compared with other quotes I received.

After much deliberation (and late nights comparing quotes I could have sworn were duplicating in front of my eyes) I eventually took the plunge with Phase Energy. Initially picked due to a vast understanding and their attention to detail compared to their competition. They weren’t necessarily the cheapest, I’ve always been a firm believer of “pay cheap, pay twice”, but a competitive quote nonetheless. The scaffolding arrived as planned. The fitters were a fantastic bunch of chaps. The install was done in 3 days. As the wary, sceptical “old fool” I am, I was reluctant and hesitant. Turns out the only foolish thing about me was my reservations towards these guys. I wish I done it sooner. Absolute pleasure to do business with. I admit - as the colder days draw in - I will probably be in touch in the near future to expand my battery storage capacity. FA

Great service from Phase Energy. From the initial contact through to installation & aftercare these guys have been great. We highly recommend them to anyone thinking about solar - they will walk you through the whole process from start to finish. Thank you again

We’ve recently started working with Phase Energy and, so far, everything has been going smoothly. The installation and setup process was straightforward, and the system has been up and running without any issues. It’s still early days for us, but we’ve been very happy with how things have gone so far and would be happy to recommend them based on our experience to date

Excellent service from start to finish. We have 108 panels installed on our barn roof and with the summer we have had we have seen our bills go from £300 per month to almost nothing. Would recommended Phase Energy.

After seeing my farm's electricity bills climb through the roof, I decided to explore solar and was put in touch with Daniel at Phase Energy Ltd. From the very first conversation, it was clear I was dealing with people who are polite, knowledgeable, and take the time to ask the right questions about my energy usage and what I was hoping to achieve. I quickly learned that they aren't your typical 'man in a van' type of company. The entire process was handled professionally and transparently. Communication was excellent throughout. Especially with Liam, with quick responses and clear explanations at every stage. The team's expertise was obvious, and they gave me complete confidence that installing was the right solution, for my ever growing bills. The installation itself was completed to a very high standard, and the results have been fantastic. They hastily completed it and made sure to leave nothing behind to signal we had work being done. I made sure to make this clear because we have a lot of customers coming to our farm and we wanted to maintain our aesthetic appeal whilst the work was being completed and they did just that! My electricity bills have gone from being a constant source of frustration to being minimal, which has made a huge difference to the running costs of the farm. Having the extra disposable income is a huge benefit to us because we finally have that extra capital to reinvest into areas we previously struggled to due to cash flow issues I couldn't be happier with the outcome. Phase Energy delivered exactly what they promised, and the savings have exceeded my expectations. If you're considering solar, I would highly recommend them. Our system has been running for several months now and although we had a couple hiccups getting everything online at first, the team were quick to not only resolve our issues. They also explained why they occurred and what to do to ensure it doesn't happen again! Special thanks to Liam for the organisation and execution of our install. He was integral throughout our install process and was only ever a phone call away! Honest team and a good company.

The installation itself went well, but everything that has happened afterwards has been an absolute nightmare. We've had multiple issues and queries since the system was installed, and every single time any action to be taken has been painfully slow. The latest issue, where the batteries arent working at all has now been ongoing for over two months and still without resolution. What has made the situation even worse is the complete lack of communication and reliability. I've taken time off work on many separate occasions after being told by Liam that someone would be attending to investigate the problem or resolve the issue. Every single time, nobody turned up. No phone call, no email, no apology, and no attempt to let me know they weren't coming. I then have to waste more time chasing for updates because nobody contacts me. We were also promised a battery backup installation. Despite countless emails, phone calls and repeated chasing, this still hasn't been completed. The installation team may do a good job initially, but the aftercare is honestly one of the worst experiences I've had with any company. Once they have your money, getting support appears to become their lowest priority. For anyone considering Phase Energy, I'd strongly advise looking beyond the sales process and asking serious questions about their after-sales support. Based on my experience, if something goes wrong, be prepared for months of delays, missed appointments, poor communication, and the burden of constantly having to chase them yourself.

Wish I never heard of this company. We spent £20.000 on a system and still doesn't work properly after 8 months just keeps triping out. Numerous phone calls and nobody ever rings me back its normally liam is in a meeting i'll get him to ring you back . I'm in Banbury in Oxfordshire and the first two cowboys that came out were a solar company from Hull they lasted a day. then two other guys turned up and had a look then said they were going to get parts never came back. Then a chap from Doncaster turned up to wire up inverters he left me with wires dangling loes over back door. On one of the occasions I did get to speak to Liam he said its working most of the time I want it working all the time for £20.000 They sent another sub contractor electrician out before Christmas he said he thought it was the wiring on roof that was coursing the problem he sent pictures to Liam and they agreed it looked shoddy and he would send a roofing team out after Christmas it's now 18th of March and still nobody has shown up. Im now going to have to pay another company to sort it out.

We recently had a solar installation completed by Phase Energy and are extremely happy with the service. Communication was excellent throughout, especially from Liam, who kept us fully informed and was always quick to respond to any questions. On installation day, Sean, the main installer, was great — professional, friendly, and clearly very skilled. The work was carried out efficiently, and everything was left neat and tidy. The system is performing exactly as expected, and we’re very pleased with the overall experience. I’d highly recommend Phase Energy to anyone considering solar

I bought a 40KW ground mount PV system with 2x20kw inverters and 20Kwh battery for my business. I paid £55,000 and now 8 weeks later the system is still incomplete, unfit for purpose, and I recieve no export payments. The contract was based on a survey by Phase energy. In their sales pitch there seemed to be no limits to what this company could do and they praised themselves for not taking payment before the system was fully completed and up and running. The weather was not good and the ground workers and installers worked hard in the rain to get the pannels installed over 3 weeks which was much longer than anticipated. This was partly due to the weather and partly due to poor organisation by the office. I was disapointed that even though I paid 55K for this system, the designers in the office could not spare someone coming out to look at the site just once to deal with issues. But as Jessie from the office said "I am in the office and to busy selling, I cant come out" Anyway the install team worked really hard to complete the install and we really appreciated it. However, I noticed that although we had clearly agreed and signed a contract for two 20kw inverters, Jessie and Liam decided to install a 17kw and a 20kw inverter. No one told me of this change and when I questioned it, Liam told me that they could not get 2 x 20kw inverters from the supplier at the time of order. They had 3 weeks to sort this out and there are plenty for sale. I was then told that it would perform almost as well and with only a 0.4% drop in performance compared to two 20kw inverters. So 0.4% in the system lifetime is just over £1000 of lost performance according to their own calcualtion at POS. They did agree to a £1000 reduction but I would ideally have wanted the correct inverter which I told them. This is absolutely not ok but luckily I noticed. I had also made it very clear to Jessie that the monitoring of this system on an app was very important for me and Jessie assured me that this would not be a problem. He had many ways to overcome the fact that there was no internet signal where the inverters and battery were to be installed. The electrician installing the inverters also had a good idea of what TP-link was need to get the system online based on its location. So the install was switched on on 12/12/2025 but work for the internet connection was to follow in early January. Despite promises of not requesting payment before the system was fully completed, Liam requasted the final payment at this point. AND how silly was I!!! On 19/12/2025 the system was completely dead. I phoned Liam and he could not say what was wrong with the system as there was no internet connection. Fair enough, but the interest in helping me getting the system online was mildly put as lacking. After sending him an email pointing out that I would have got better support with sour milk in Aldi than from him I finally got the info I needed to reset the system manually. The system has since been offline 4 times and despite me chasing Liam up in January he could only give poor excuses and he has shown zero interest in fixing this. Absolutely unbelievable when a customer has paid £55k and the system is now still not fit for purpose. He has also failed to supply me with the DNO details which I need in order to get my companys export payments. This is the whole buisness case and there is clearly no appreciation that this is now losing my company money every day. It is now early February and Liam has still shown no consideration to the fact that his install is unfit for purpose and what he should be doing. So I am now contacting NICEIC to see if I can get the system removed and have my money refunded. Next step is legal. I had alot of sympathy for the issues due to the poor survey or what ever went wrong there, as well as the deliveries and the poor weather. We even gave the team some money for their hard work. But sadly Phase Energy has no consideration for peoples money and with Liam being the director it comes right from the top!

Fantastic company to deal with from start to finish.

I am very happy with my solar install, the system is working very well, and I very happy with the installation configuration. PhaseEnergy arranged the install quickly and gave good advice. The scaffolders managed to bridge over our conervatory despite the kitchen extension on one side: and that is no mean feat! Communication and follow up has been excellent. The quality of the work was generally high and I am a bit of a perfectionist. The price was very competitive. There were a few minor hiccups along the way but all fixed and no big deal. The 5 stars reflects my view of the final result. I would use PhaseEnergy in the future and I do recommend PhaseEnergy's services.

Great company to work with. Very efficient!

Initially, I had doubts about using Phase Energy SE Ltd based on the fact that their trading history was limited. However, I decided to give them a chance, and I'm incredibly glad I did. Their team was professional and efficient throughout the entire process. They skilfully installed a 16-panel system on my garage roof, paying great attention to detail and ensuring everything was done to the highest standard. The results speak for themselves. My electricity bills have been reduced by an astounding 80%, which I find to be highly impressive. This significant decrease has not only saved me money but also given me peace of mind knowing I'm contributing to a greener environment. Overall, I am extremely satisfied with the service provided by Phase Energy SE Ltd and would highly recommend them to anyone considering solar energy solutions.
