Hi Gerry, I would like to formally acknowledge in writing how satisfied we were with the recent water conservation devices installation works completed by Renergise at various Aura Leisure Centres. We have had immediate saving in our water consumption of approx 40%, which is excellent. As a result of saving water, our fuel bills have been reduced also. Also I would like to thank you for the immediate response to the faulty fitting we had in the changing village in Carrick on Shannon. Your installers were very accommodating and nothing was an issue. They worked around our operational constraints and ensured absolute minimum disruption to our customers, in spite of the very tight time frame you had to complete the works. The few snags we had were addressed immediately and to our absolute satisfaction. Thanks again and we would have no hesitation using Renergise in the future.

Regards, Padraig Byrne Maintenance Manager

Friends First Life Assurance Co Ltd

To Whom It May Concern Friends First Lift Assurance Company contacted Renergise Ltd in 2010 as part of the Green Project we were implementing. We wanted to reduce our water consumption in the building. Renergise put in the following solution for us. The installation of Flow Aerators in all the sinks, bathrooms and tea stations conserving our water. The replacement of old taps, non Regulated flow taps with excessive water flow ranging from 12 Lpm to 20 Litres per minute.. And with the new system this reduced the flow rate down to 4 Litres per minute. We have reduced our water bills by 30%. The whole process was handled very efficiently and professionally by Gerry. It was a pleasure to do business with someone who believes in the company he represents and their products. In short I would recommend Renergise to anyone considering water conservation.

To Whom It May Concern, I would like to confirm we recently used the services of Renergise for a large Primary School in Killarney, Holy Cross National School, on our behalf. We asked them to carry out an analysis of the water consumption in the school. From the analysis we received, it was clear the school was consuming excessive water and as a result paying excessive water bills. Under the advice of Renergise we carried out remedial actions and the benefits are very encouraging. The latest water meter reading we received showed a reduction in water consumption of up to a third of previous consumption. We found the company very professional and easy to deal with, and we would have no problem recommending Renergise for projects of a similar nature.
