Next-Gen-Power 

⭐️⭐️⭐️⭐️⭐️
Exceptional Workmanship & Trustworthy Team – Highly Recommended

Louis, Jake, and Davey from Nexgen were absolutely outstanding from start to finish. Their work ethic was second to none — grafting hard every day, staying late when needed, and never cutting corners.

Right from the beginning, they walked me through exactly what they were going to do. Their communication was clear, respectful, and consistent throughout — I was kept well-informed at every stage, which gave me real confidence in the job being done.

Their attention to detail was spot-on. Every part of the job was done to a very high standard, and they took real pride in getting everything right — no shortcuts, no rushing. They even made sure my dogs were safe, calm, and comfortable while the work was going on — which says a lot about the kind of people they are.

I trusted them completely — even leaving them with my keys while I attended meetings. They locked up for me and even posted the keys back through the door. And to top it off, they cleaned everything up afterwards, hoovering the house from top to bottom. You’d barely know work had been done, it was left so tidy.

These lads are a true credit to Nexgen — hardworking, trustworthy, professional, and genuinely kind people. Can’t recommend them enough!

Thanks again for all your hard work guys

Customer service is absolutely terrible. We have been assured four times since March that the paperwork for our grant would be complete. Our grant application is now running out as we continue to get empty assurances that the paperwork will be completed by Next Gen.

I had the panels, the inverter, and the battery installed by Next-Gen Power NI in June 2022. All was working well until the 31st of March this year. Suddenly, the battery stopped charging. I reported the problem on the next day, the 1st of April, and... nothing. An engineer attended, confirmed an inverter fault, and the system has been off for over 7 weeks. I realised their warranty has NO TIME FRAME, so that they can replace my inverter in 100 years... under the warranty. I have been ringing many times, but nothing has happened, not even a date for fixing it. I am very disappointed...

Excellent after sales service, thanks to Mathew and Patricia for responding so quickly.

Had a few issues with storm damage and had to wait a while for it to be fixed. After a few phone calls all was sorted out to my satisfaction. I would recommend Next-Gen-Power. Thanks to Patricia and her team for all their help.

We've had the 14 panels since January 2020. Great system, saved us a packet, and now we are getting a feed-in-tariff, pays off quicker. One small issue. The dongle is not reporting back. So, if you could fix that!

Very poor customer service from nextgen. They have never returned our calls or done what they promised. Their invertor and battery cover was poor quality and was blown off in a storm. We have had two storms in two years with a power cut resulting. Each time next gen take over a month (or two) to return and jump start the battery, so our solar goes to the grid in the meantime

I'm very happy with the GivEnergy system (6.7 kW panels + 9.5 kWh battery and inverter) that was installed by Next-Gen Power. They were very good at responding to all my questions (and I had a lot) in advance of installing the system, and gave what I felt was a good price (after extensively reviewing about 10 other solar installers). The warranty on the battery, inverter, and car charger are all very good compared to other equipment. I also reviewed the GivEnergy system and software extensively before choosing to go with them - they have a very good reputation, they are based in the UK so have been easy to contact when needed (which I'd image would be trickier for the likes of Huawei equipment), and the quality of the equipment seems high now that it is installed.
Couldn't rate Matthew (the electrician) and Liam (the roofer) who installed the system any better, both great to deal with. Matthew did a very neat job on a complex wiring set up for our house.

There were some issues with getting the car charger set up, and some minor damage to the roof caused during the install, that took maybe 4 - 6 weeks to get corrected, but they are now fixed. I feel that timeframe was ok given how hard it is go get someone in the trades in at the moment.

The only other thing is the sales team promised the moon and stars with the system, and a couple of times the install team were a bit blindsided by what was promised. Nonetheless we managed to work through it all.

I've had no issues with the system since it's been up and running in early September.

Very good experience with next gen power. I had a 6kw solar system installed last month with 3.6kw GivEnergy hybrid inverter and their 9.5kwh battery. Everything works smoothly so far and the installation was very tidy. The work was done before the scheduled date which is even nicer.

Next Gen over promises and under delivers.

We agreed to pay them in full if they could guarantee an install before the end of the year in 2022. Paid them almost €25k for the install.

From the beginning they never followed through. The install didn’t happen until March and they contracted out the installation of the whole system, including electrical. The panels were installed a month before the electrical work was undertaken.

After the system was finally installed, I was told Next Gen over spec’d the project for my home which lead to us not being able to claim our grant. To be fair to them, they made up for this and credited back the grant amount but there were issues with the system from day 1. The breakers kept tripping and I was constantly calling to get a call out for service. I was ignored and eventually received a response saying they were going to place a call out. I had direct communication with the electrician that installed the system but he said he wasn’t working with the company anymore and couldn’t assist.

In January 2024 I was told someone would be out to us in a couple of weeks. Heard nothing after that. Out of nowhere, 7 months later, installers showed up unannounced to check the system. They disconnected the earth and said that it should be solved but 2 days later, still the same issues.

I wouldn’t recommended dealing with this company in any shape or form. They are quick to get paid but they under deliver on service.

When the system is working properly it works well but the after care service is terrible. The first year was a right off as the system was constantly faulting out. Once resolved everything worked well but unfortunately it has a fault again and I am waiting two months now for an engineer to call to rectify the problem.

Two months since installation and 1 Mwh of generated energy later and I couldn’t be happier with the 5kw Solar PV and Givenergy All In One system installed by Next Gen-Power.
Jacob was very helpful and knowledgeable during the configuration of our system, Patricia was amazing taking care of all the paperwork to make sure everything was done on time, the roofers did a very clean job and Mathew did an extremely neat installation of the All In One, Inverter and Gateway.
And the cherry on top of the cake, my first bill after installation and I am already building credit, even with charging the EV.

- Changed to 1 star

No response to emails or phone calls.

Got our system installed at the end of Oct 2023 and immediately had issues with the installation. The first issue which was resolved quickly only by turning off the system for a number of days while waiting on a part was the battery kept charging and discharging. As we got 2x 8.2kWh batteries and we were charging from the grid it cost us an extra £200 on top of your normal electricity bill for that quarter! We are only really recovering from this in the last month.
Once this was fixed another problem arose with the integration with the current solar system already in the property. There were multiple attempts trying to fix this and ultimately wasn't resolved for over a month. To the credit of Next-Gen Power they were initially very pro active in trying to fix the issue but towards the end I wasn't 100% sure they thought there was actually a problem. Ultimately I took it into my own hands and traced everything and approached them with a solution which was placing the c-clamp onto the tails coming into the property rather than inside the consumer unit itself. Once approached with this fix they came out promptly and moved the clamp which fixed the issue.
The last issue I had was around what happens if there is a power outage and the batteries don't work. I asked for a quote which was refused based on that it couldn't be done. I went direct to GivEnergy who said that it is possible. When going back to Next-Gen Power they confirmed that they are refusing to quote. Not really any meaningful explanation given so had to look elsewhere for this to get done.
Ultimately the system works great but there were a few issues and the interactions when there were issues have left a sour taste especially that I ended being charged a little over £200 more on my electric bill that month.

While the system functions well to the best of our knowledge we have five issues with which we are unhappy and we would really appreciate it if you could addtess them.
1. The most serious is that when you sent an engineer to carry out a BER test he gave us a shocking low rating D1 despite our instalation of 16 Solar panels, double glazing, attic insulation, wall insulation, one fireplace now with a woodburning stove, and a new Grant condenser oil heating system.
2. We were never given instructions on how to register or use the APP.
3. We called a few times because of our being unsure that the system was working and were told a representative would call but this did not happen.
4. After a power cut some months ago we noticed an unusually high bill and on looking at the eddie it appeared to be off. It was only after I located a switch on the side of the battery that the system restarted.
5. It is most unsatisfactory that when there is a powercut, the solar system also goes dead. This is not the case with others who have installed solar systems as they are given the means of switching to battery only power.

Overall while we have a sense that we are saving on energy costs the aftercare has disappointed us and that is to our regret.

Next-Gen Power are a fantastic company, I'm delighted with the GivEnergy AIO system they installed for me, thier general approach, service levels and workmanship.
They were one of the few companies I dealt with who actually listened to what I wanted, and selected the appropriate system, tailored to my needs, as opposed to the most common approach I encountered from other companies , who tended to want to sell you what they have and what they ‘usually do’, which is not the same at all as what you 'need'.
Their pricing was also extremely competitive, by far the best kWh/€ value for both solar and battery capacity. Their installation teams also did a super job, so neat and tidy.
Could not recommend them more!

Got 14 panels installed in 2019. Took just a couple hours and was very impressive to see. System is working without any problems since. That we now get some money back from the overgeneration in summer
makes it even more attractive. We are very happy!!!

We have 36 solar panels and 3 (5kw) batteries. All installed in the second half of 2022. Job well done made and everything works perfectly. THANK YOU
P.S. Thanks Patricia

Next-Gen engaged with me for Solar PV in 2019 and I have had a very positive experience since then. Install went smoothly and adjustments were not a problem at all. Any issues I had with the system were quickly assessed and actioned with minimum fuss. I would highly recommend Next-Gen-Power as a preferred supplier of Solar PV. Very happy with their service.

We got our solar panels, inverter, battery and microdiveters for hot water and ev car installed in 2019. Despite a few issues over the years we are very happy with the system. Patricia, Lee and Mark were always quick to help out and we have had an inverter replaced under warranty, as well as an upgrade to the battery. With the new microgeneration tariff and battery for winter use we have very low energy costs, couldn't recommend the system highly enough.
