Just an update on last weeks review.

After another weekend of sitting in the cold we had another no-show from this pack of con men today.

Tell Ollie Hughes that he can contact us any time he wants via the same e-mail that he used to hound us for looking money but he is obviously too much of a big timer these days to bother with his customers unless there is a camera around.

Do not give this company the time of day.

Waited for more than a month after which the call was cancelled and said it would be through phone and not teams call. Never heard back after that. We have got the assessment completed a year back with them. Waste of time and energy dealing with them. Extremely unprofessional company.

Thank you for taking the time to share your experience, and I’m really sorry to hear how this has unfolded. Waiting over a month, having your appointment changed, and then not receiving a follow-up is not acceptable and falls well short of the standards we aim to deliver.

Given that you had already completed your assessment with us, I completely understand how frustrating and disappointing this must have been, especially after investing your time in the process.

This clearly shouldn’t have happened, and we would really like the opportunity to look into what went wrong and put things right for you. If you’re open to it, please contact us directly at info@ohkenergy.com with your details, and we will prioritise your case immediately.

I got basic system installed by them via electricireland few years ago.
Wanted to do more panels and work and despite emailing, phoning amd leaving messages, no replies!!
Wanted advise on current system but no contacts !!
They probably thrive via Govt grants plus personal connections in big companies as it seems.....
I will NOT go to them again .
They have changed their name to ohk or something now!

Very slow service

Very slow service , the solar failed and Electrician failed to turn up for the arrange appointment after waiting nearly 2 weeks for an appointment , Have to wait another week for the next appointment and no guarantee an electrician will turn up for the next appointment either , So it will be three 3 weeks since solar generation failed before it might get looked at . I would expect service to be quicker.

We’re very sorry for the delay and for the inconvenience this has caused. We completely understand your frustration, especially when you have already waited nearly two weeks for an appointment and the electrician did not arrive as scheduled.

This is not the level of service we aim to provide. While there are occasions where delays can occur due to availability or unforeseen issues, your system failure and the missed appointment should have been handled with clearer communication and greater urgency.

We appreciate that being without solar generation for this length of time is unacceptable, and we understand your expectation that service should be quicker. Please contact our office directly so we can prioritise your case, confirm the next appointment, and ensure you are kept informed every step of the way.

Thank you for raising this with us, and again, our sincere apologies for the experience.

Female customers beware

Myself and my husband had an online meeting with a rep. I introduced myself at the start of the meeting. After a boring 45 minute presentation the rep asked my husband what he thought-completey ignoring me!! My husband deferred to me and when the rep quoted us I was so annoyed I said I'd pay €4k less than what he quoted and he said yes?!?!!! Ridiculous, sexist and untrustworthy. We obviously didn't go with them

I recently had my solar system installed by NRG Solar, and I’m very happy with the entire experience.
The team — two electricians and two roofers — worked efficiently, professionally, and with great attention to detail. They were polite, well-organized, and left everything clean and tidy once the job was done.

Special thanks to Rob Cook, who managed the project perfectly from start to finish. He was clear in his communication, answered all my questions, and made sure everything was completed to a high standard.

Overall, NRG Solar delivered excellent service and workmanship. I would definitely recommend them to anyone looking for a reliable and professional solar installation company.

Glycol - top up

I am extremely disappointed with NRG Panel. They were supposed to come on 16/10 to top up the glycol. They showed up, charged me €205, but in reality did absolutely nothing.

I only discovered this year that the work I paid for was never carried out. This is unacceptable, unprofessional, and feels like outright dishonesty. When a company charges for a service, the least they can do is actually perform it.

I would strongly advise anyone considering NRG Panel to think twice before using their services. Based on my experience, I cannot trust them and will not be dealing with them again.

Thank you for your feedback. We’re sorry to hear of your concerns and would like to clarify the service that was carried out.

A full service was completed on your system on the date in question. During this visit, our engineer also identified a leak on a factory fitting. While this was outside the normal scope of a standard service, the engineer repaired it on the spot to ensure your system continued to function properly. This was done at no extra charge, despite the additional time required.

At the time of service, the glycol concentration was tested and measured at -5 degrees, which provides sufficient protection for your unit. For reference, glycol top-ups are only required if the concentration is at -3 degrees or above. As such, no top-up was necessary and therefore was not carried out. Please note that adding glycol is not part of a standard service scope or costs.

We hope this explanation provides clarity, but we are happy to discuss further if you would like to review the details of the service with our team.

No Cert??

Hmm, not sure what to think of Ohk energy yet. I had organised a BER assessment for my home with the potential to doing energy upgrades. The BER assesor was out and completed the BER, but 4 months later I still haven't received the certificate or been contacted by Ohk energy at all.

I had a heatpump installed 3 years ago, service was great. Most recently, the heatmiser hub has stopped working. Despite multiple calls and emails over the past 2–3 months, I have yet to receive any support. This level of service is simply unacceptable.

It's been a great experience from the beginning staff are incredible and great customer service I'm delighted with my panels and overall smooth process. What really stuck out was the staff that do the grant process I put in my own bank details instead of my Partners as the grant would be in his name. Got an email from saei but I would never look at emails so completely missed it. I got a phone call from a very lovely girl called Aimee and she made me aware about this very pleased with this company and would recommend them to anyone, excellent communication

storm aftermath

We are so thankful for the staff from NRG after the storm last week. We made a call on Monday to NRG and knew with so many in trouble we could be waiting a while. The engineer arrived on Tuesday and checked all the panels. We had had the foot of the panel slip and he realigned the panel and made sure all the rest were safe . We have a review here from the installation and just to confirm that we are 100% happy with both the panels and service from day 1 with Francis . All the paperwork completed in no time just to sign. The panels have been a great success to us , mind a little slow in late 2024 with the fog and cloud and lovely winter . and that was down to weather nothing else. The worry we had last week in the height of the storm when the panels were shaking and felt like the roof would come off, to only have a foot slip we were lucky . Thanks again NRG for the great back up service

I give one star but really it's zero

I give one star but really it's zero. Booked a consultant online for one stop shop as our home has defeative block and we are due to demolish. The website say book a free consultant and there was absolutely nothing free about it. They contacted us and said we need BER rating and they need payment upfront for €650 for the BER that was the consultant. We made the payment waited week and had to chase them up final sent someone out to do the rating again had to wait weeks before we heard back. Only for them to tell us our house was air tight. What a joke, anyone who has a defective house knows there is not way they are air tight, even with the fire light and heating on the house is freezing. The insulation in our attic space is landing on the floor the draft coming through the windows is ridiculous and during the last storm my front sitting room was flooded from water coming in the front windows. Was a waste of time and money. Wouldn't advise anyone with defective blocks to use NRG.

I asked for a quote to replace an inverter they fitted for my father a few years ago. They insisted to come and have a look at the inverter with a call out £180 charge for 5 minutes . I them asked for a quote to replace said inverter no reply. After 5 phone calls no one got back to me, a total waste of £180. I am now using another company and will not go back to them ever.

AVOID

AVOID

Set up was great. Salesman was very knowledgeable and having done our due diligence on three other companies, including having them out to the house, we were happy to proceed. Installers irked me a bit when they didn't arrive anywhere near their scheduled times but I let it pass as the installation went rather quickly.

The reason for the 1 star review is their after service. It's ridiculously poor. We switched internet providers and not only did it bring down the system's ability to record data or provide us with hot water (via our Eddi) no one at the company had the first idea how to fix it. They kept fobbing us off with redundant instructional videos and didn't seem to know the first thing about what they were selling.

We feel incredibly conned and will be considering how we can get our money back.

Hi there Patrick,

Thank you for sharing your experience, and I sincerely apologise for the issues you’ve faced with our aftercare service, this is not the standard we strive for. While I’m glad the initial site survey went smoothly, it’s clear we fell short when it came to resolving your post-installation issues.

Your concerns are very important to us, and I’d like to ensure this is addressed properly. I will personally escalate this matter to our technical team to identify what went wrong and provide you with a solution as quickly as possible.
