Ohk Energy Reviews 

Overcharged for additional services/products. I got quoted 4,650 for a 9kw battery while a price match was 3,915. When I pointed this out to OHK I was hit with a threat that it will impact my warranty if I go elsewhere. Very disappointing after-sales experience. Avoid.

9/5/26 Update - OHK rolled back on the threat to my warranty. There are however tonnes of examples of others having the exact same issue with OHK on the SIGEnergy Ireland Facebook page. Id think very carefully before going with OHK. The SEAI shouldn’t be supporting this behavior with public money.

On the day of installation of our solar panels there was little to no disruption to us. Everything ran smoothly and it was a great service overall

The initial visit from Mark was very informative and answered all of our questions, we really appreciated his time. All work went to plan, we were kept well informed. All of the tradespeople, electricians and installers were efficient and tidy and very easy to deal with. Any questions we have had post installation have been answered by the office staff in OHK, we were apprehensive about this new technology, applying for SEAI grants, choices to be made etc, but it has all worked out very well due to the level of communication and workmanship. Thank you all at OHK, I would have no problem recommending you to friends and family

The consultation by Sean was very informative and helped me understand my current and projected future costs along with some areas of electricity usage that I needed to investigate. He also explained the best tariff that I should apply for best on new solar set up and my usage.

The install process was non intrusive, it was scheduled and done whilst I was away from home. The lead engineer called me with updates and picture to ensure I was happy with the install before signing off.

The BER Cert and Grant application was all handled by the Ohk team and was seamless.

Above all that I found the cost very competitive and I am already, even with a damp Jan and Feb, starting to see the benefits with more hot water, reduced grid intake which has seen lower monthly electricity cost.

I got good advice from outset, a clean and tidy install done at quick turnaround and a system im very happy with and is performing better than expected.

The cost was very competitive, but I feel I got an above value service and product so couldn't be happier.

Strongly recommend.

They left nails and roof tacks all over the grounds. Sloppy.

Very knowledgeable engineers, flexible and accommodating scheduling. System itself is also great, you can set and forget, or go as detailed as you want, theres even a third party home assistant integration.

I had a service done on a heat pump by OHK Energy recently and I have to say I'm surprised in what these guys are doing in peoples homes. I said I'd mention this so other people are aware of it and does not happen to them. I explained to the guy when he first arrived that he was to use the utility room sink for any water and cleaning of items. I said to him to let me know if there is anything else you need. He went out to get a bucket and went into the utility and started to fill with water, he then helped himself to the Cabinets in the utility looking into them and getting out washing up liquid without even asking me for it. It wasn't until after all this was done I realised what had happened. Not nice having someone going through your Cabinets with out you knowing it. Also he was very keen in wanting to use our bathroom sink to empty out all the dirty water from pipes even tho I said to use the utility sink for all of that. In fact, this did happen before from the previous person that came a year ago and helped himself to our bathroom sink without me even knowing and left it extremely dirty. He also went walking around the house looking for a outdoor tap, again, never asked me. He also asked to used our toilet, luckily enough no pee on floor. Sounds very like the the person that left a review on 18 Sep 2025 by someone else and descried him as 'black haired man with a donegal accent' This was the same for me, I'm not sure how many Donegal accents guys are working for OHK Energy but sounds very like it. The guys need to have more respect for peoples personal space and belongings in homes. I definitely wont be getting OHK Energy again after this second experience.

Ohk Energy amazing to work with... Made it easy and very informative on price install and information. All question were answered direct and timely... Overall a good experience from start to finish.

Every member of staff have been helpful, polite, knowledge, friendly and professional.
They take the time to explain everything involved, to make the Solar Panel experience easy, they prioritise working with and for you, at your pace & to do things to your time table, when it suits you. They are flexible and facilitate their customers rather than "Their" schedule.
No hard sell, no sign today or the price goes up ~ they have been a hugh pleasure to do business with.

I had to reschedule installation on 4 different occasions Started process in Oct' 2025 For personal circumstances/reasons I wasn't in a position to have the instillation start untill Feb 2026 ~ no problem, they were there to work to my schedule. An amazing customer service.
What's more, if they didn't have and answer to a question, they would check it out & always phoned back.
Exceptional customer service.

We recently had our solar system installed by OHK Energy and overall the experience was very positive from start to finish. The team were professional, punctual, and clearly knowledgeable about the system they were installing. Communication throughout the process was good, and the installation itself went smoothly with minimal disruption.

The system was only installed recently, so we are still learning how to optimise usage, especially during winter months when generation is naturally lower. However, everything is working as expected and the supplier has been helpful in answering follow-up questions as we get familiar with the app and energy management.

Installation quality and workmanship were excellent, and the setup was completed on schedule. It’s clear the team takes pride in their work.

I would recommend them to anyone considering this system, particularly for the professionalism of the installation and overall service provided

They made the solar panel process very simple. Very easy to deal with. Excellent workmanship done with de panels and battery. I would highly recommend OHK.

Everything was good from start to finish.installers and electricians were very professional and obliging.

Ohk Energy are a great company to deal with. They are very effecient. They give great advice and workmanship is first class. Very happy all round.

Very professional installation and sales team

Got installation done a while ago in Tubbercurry via electricIreland with NRH (this company name at that time) and now not responding !!

The work was done in only a few hours, which was great. The guys doing the work were fully professional and helpful. The Commisssioning problem was followed up on quickly (although I had to make a phone call to hasten it). So, overall I would be happy to recommend Ohk Energia to other people.

Very efficient and helpful workers, a pleasure to do business with them.

Very efficient, pleasant people installed my solar panels . Great job ! Thank you .

On time ,professional job done right ✅️
