Berth Sheehy of Energywise Ireland completed the installation of works at our new factory. We found Berth and his team very easy to deal with and knowledgeable on all areas. The installation comprised of covering a site of approximately 11 acres with single and three phase electrical supply for offices and industrial equipment, backup uninterruptable supplies for IT equipment with generator and UPS, a state of the art computer network for computers and IP telephony, wireless lan infrastructure for both data and voice traffic over the full site, knx building management and low energy lighting. I recommend them 1000%.

Energywise Ireland have recently completed a number of projects for our firm including the new 90 Bedroom Charleville Park Hotel and Leisure Centre with 25m swimming pool and nightclub. A new forty-bedroom extension to the Lake Hotel Killarney. A new therapy swimming pool and ancillary areas for St. Josephs Foundation Charleville. We were extremely pleased with their performance on these projects in terms of the installation on site, workmanship, attention to detail and competitive pricing. We would have no hesitation in recommending them to any prospective client for future projects.

The Lake Hotel had a deadline of 8 Months to complete our 40 room extension, we needed contractors who could deliver while maintaining standards. Energywise Ireland was one of those contractors who delivered. The teams professionalism and work ethic meant that we now have a top class hotel. We still use Energywise Ireland and they have since worked our new Restaurant and additional 10 Bedrooms.

Energywise Ireland completed the installation of our smart electrical systems at the Charleville Park Hotel, Leisure Centre and nightclub. The team was extremely professional and knowledgeable on all areas encompassing smart wiring and also in the integration of our many control systems.


William Savage, Charleville Park Hotel



I had been researching the new developments in renewable energy for a couple of years in preparation for my build. I met the Energywise Ireland team at their showroom in Blackpool in Cork City and found the team to be very knowledgeable. From the initial enquiry stage right through to the aftercare service has been of the highest quality and the ability to pop into the showroom at any stage is very reassuring. The team provided me with design drawings in advance of all works which gave me great assurance that I knew exactly what was being done in advance. The house is always very comfortable and we can’t believe how fresh the air is within our home. Our running costs have been very low to date and we are looking forward to a lifetime of comfort in our new energy efficient home.


Liam Looney, Blackpool, Co.Cork



Energywise Ireland were competitively priced at 15-20% lower than other suppliers offering similar services. They took the time to take us through the new systems being installed and the benefits and cost efficiencies of same. Darren and Berth and the team were extremely professional and knowledgeable. We are blown away by the perfect fresh air and heat balance that the combination of systems has achieved. The house temperature remains at 20 degrees which is a blissful living environment for an Irish winter. Thanks lads for making our self-build easy!

Energywise Ireland installed the electrical, led lighting, geothermal heating, HRV and central vacuum in our new home. We found Berth and his team to be very pleasant, focused and committed to their work. Their work was of a very high standard and Berth was always available to discuss any issues that arose during the project and provided invaluable advice. It was a pleasure to have to deal with just one company to cover so many services. I would highly recommend Energywise Ireland.


David Gaynor, Tralee, Co.Kerry


For a few years we have been considering the addition of a PV solar system on the roof of our home in County Kerry. We spent many hours researching available systems, ESB tariffs, size options, costs and all other aspects. We spoke to a handful of good companies about the subject. In the end we made the decision to give EnergyWise Ireland the go ahead to install a system. They laid out the complete project proposal for us to consider. They paid particular attention to our concerns about the effect high wind might have on the solar panels; our home is situated near a tidal bay subject to high winds in the winter. They outlined their reasoning for recommending the solar panels and the inverter manufactures; all the warranties and advantages. They oversaw all the official documentation needs, and they advised us on the process with ESB. On the two days of the installation, they were clean and professional. In fact, the wiring from the PV panels to the fuse panel and Inverter is the tidiest wiring in our home. Our system today cranks out power trouble free. In installing this system, we have effectively slashed our electricity cost permanently. We look forward to twenty-five plus years of greatly reduced ESB bills. I recommend EnergyWise Ireland even if you are just considering the option of PV solar panels on your home our business. They have the experience, expertise and resource to provide a professional first-class service and an excellent finished job.

Damien Clifford, QS, JJ Rhatigan Building Contractor



I just had the SEAI inspector looking at the solar installation today and he was super impressed. He said it was one of the best installs he has seen. He said everything from trunking to labelling was very impressive. He said it was great to see such an excellent professional job, zero issues found. Original review below –
10/10 – The work carried out was to an excellent standard and they installed a great solar system. The staff were amazing and they answered all my questions after the install. After install care was amazing. Highly recommend Energywise.

Recently got two air to water units and also 16 solar panels from energywise. Found them top class to deal with, had no problem getting grant application sorted with them and also very helpful when I went looking to become a microgenerator with ESB. Christina in the office is very knowledgeable and helpful.

Owen Glynn


I had my old MVHR unit replaced by Energywise, as well as an Air to Water Heat Pump retrofit (for a Heat Pump Grant) – very happy with both jobs.
Everyone I spoke with was very helpful, particularly Bryan and Kenneth – gave me a lot of great technical advice and even helped identify the source of a problem with the water tank I had.


Monika Wielogorska


The Energywise team provided an excellent service for several heat pump projects. From design phase and helping choose the most appropriate systems, through quick and timely installation, to assistance in ensuring the new Heat Pump systems were working optimally. Very impressed throughout.
