What our clients say about us

"We had a retrofit done on our house in July 2024. House was wrapped, new windows and door, air to water heat and solar panels. Everything is now run on electricity. No oil, no coal, no gas.

The solar pv. panels are wonderful. We have had no electric bill during the period February 2025 and January 2026. My next bill covering February and March 2026, I expect to be about €100. €100 for 12 months is just unbelievable, as we have plenty of heat all over the house and plenty of hot water .

We did a one stop shop with Harte Home Retrofit. The workmen came day after day and though the job took longer than expected, I never had to worry about the job not progressing as I knew exactly what was happening all the time.

Expensive yes. Was it worth it, yes. Plenty of heat and plenty of hot water.

E & S McGrathCo Waterford

“I used the team at Harte Home Retrofit to carry out extensive extension works and a full energy and heating upgrade to my home. From the planning phase through implementation there was excellent collaboration to find the optimal solutions to meet my needs and great knowledge on grants and best practice in the area to ensure costs were controlled.

The final result is a transformed home with space, light and amazing cost efficient heating throughout. I would recommend Harte Home Retrofit without hesitation”.

Richard CuddihyCo. Kilkenny

“Harte Home Retrofit and all the team were very knowledgeable and professional. Stephen was very easy to deal with, took his time to explain everything in detail and was quick to respond to any queries before, during and after the retrofit. Even though not everything was straight forward with our house, he was very good to advise us about the most practical, feasible options and made sure our expectations were achievable.

As Harte Home Retrofit is a smaller company, they took personal responsibility and ownership of our project, which may not be the case with larger businesses.

We are very happy with the result and now have a lovely warm, comfortable and more energy efficient home”.

Vera and Oliver KluteCo. Kilkenny

“I would highly recommend the Harte Home Retrofit Team. From the very first phone call until project completion they were available, approachable and professional. The house was old and not straightforward and their understanding and experience ensured that we ended up with a warm comfortable home while not compromising the look of the house. Their advice and recommendations meant adjustments to our original plan but this attention to detail and understanding of what was best for the building has resulted in a finish and comfort level that was above expectations and had minimum impact on the budget. I again, would highly recommend the Harte Home Retrofit Team.”

Kieran DunneCo. Kilkenny

"ERI and Stephen looked after the retrofit of our 1980s bungalow. A professional job from start to finish, but what really surprised me was the turnaround as soon as the contractors Harte Home Retrofit started work. All lined up, ready to go and work done to a high standard. Project management was great and saved us so much stress.
Would highly recommend using ERI and the team at Harte Home Retrofit, if you're considering an upgrade. We have a wonderfully warm and efficient house and value added."

AilbheCo. Kildare

“We cannot speak highly enough of Richard and his team who were consummate professionals from start to finish. They were a pleasure to deal with and completed all work to a very high standard. In particular they were always available for advice and to offer solutions to all the little snags and unforeseen problems that arise during a retrofit. We have since recommended them to family and friends and we would have no hesitation in recommending them to anyone seeking energy upgrade or construction services”.
