Phase Energy SE Ltd Recenzje 

From quotation to installation all went well, timely and ordered manner thanks. The system works well and the saving are real which is great to have given these difficult times. Happy to use again in the future.

Good customer service from phase batteries working great

The products were great. When things needed to be rectified trying to get hold of someone was always tricky. But everything was sorted out

Liam has been very helpful and supportive throughout the installation process. We’re seeing the benefits of solar power already and the batteries. Wish we had had 4 batteries installed to start with but our choice to go with 2 and then we contacted Liam again a few months later to organise a further 2.

Very good service, very helpful

We have had a 15-panel Phase Energy solar panel system for a year. Unlike other contractors who offered a "take it or leave it" design, the Phase Energy team worked through several iterations with us to optimise the solution for our home, which had several roof angles to accommodate. The installation of panels, inverter and battery was planned well and smoothly delivered. Since then, we have been happy with the system and calculations suggest that it has delivered ahead of target. We have have had some queries concerning obtaining and understanding the data output on generation etc., which Phase Energy have been very ready to assist with. Overall, I am very pleased to recommend them.

7 months in we are delighted with your panels and they are certainly worth fitting and are paying at £8 per day and saving £15 per day on our normal electricity bills. Due to the tax relief we gained at the time of purchase, we would recommend Phase Energy. Thank you for our savings.

Recently had a solar and battery installation by Phase and I couldn't be happier. From the team in the office to the guys who worked tirelessly at my home, they have been brilliant from start to finish. Great job, keep up the good work!

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.

What a great company - very professional from survey to installation! They explained the use and benefits of solar panels very well, then sent over a survey document for us to read. They arrived on time and left everything clean and tidy after installation. 5 out of 5 - would definitely recommend.

Friendly and helpful staff, especially when it matters!
Enjoy watching to see how much money we are saving

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.

Good pricing, efficient installation, after the system was installed we had a glitch which was quickly fixed

We did have a few teething problems with our PV system which I had not anticipated.
To be fair Liam was suitably understanding and did everything required to get to the bottom of the issue. I would definitely use them again if we want to expand our array.

It’s always a worry when responding to cold calls but on this occasion I was very glad I did. Phase Energy are excellent, their staff are experts and know their stuff and I will certainly be using them again.
There aren’t many people who have this depth of knowledge about electricals.

I left it a year after installation before leaving this review in order to get a full seasons worth of data and i can confirm Phase energy were extremely accurate with their proposal.

Our installation was a small business, 80 panels in total and all was done in a day with the scaffolding erected the day before and removed the day after.

All very well done. couldn't ask for more.

From start to finish Phase Energy were a great company to work with.
The whole team were easy to talk with and had a friendly attitude.
Any issues were resolved quickly and professionally.
Very competitive on pricing.
Definitely recommend talking to these guys if you’re thinking of installing 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 in February 2026 the system is still incomplete, unfit for purpose, and I recieve no export payments.
Liam has not tried once to rectify the issues or even contact me of his own back. I have chased him up just to get poor excuses and no progress.

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 instalation team seemed to be poorly instructed and even the fact that the ground was sloping seemed to come as a supprise! Not the instalation teams fault but some comunication problems clearly.
Materials arrived from the day before install (inverters) and during the first two weeks of install including lories turning up to a private property at 8pm asking for a forklift! This meant that I had to help the driver offload equipment that should have been offloaded with a forklift. It was no problem (apart from missing an apointment at my sons school once) but it may be worth others knowing.
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 to chase him up 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!

Shame on you!!! Please spare me anymore excuses althoug I am sure your response will have lots of them.

Really bespoke service, friendly team and dealt quickly and fairly with all the challenges we had including running building work concurrently and ensuring the install was very neat and how we wanted it. We went for 16 panels & Powerwall and couldn't be more pleased, it's simple to use and saving me money.
