"Merrion Security were awarded the contract to update the CCTV and door locking. They started the installation on the date agreed and the engineers went about their work in a very professional manner and were very aware of the location risks present in a financial institution. We have now switched all our fire and security services to Merrion and would have no hesitation in recommending them." Fiona Kane, Firhouse Credit Union Manager


"Switching to Merrion Security has been one of the smoothest changeover procedures. During the 1st service visit, the engineers checked every camera, alarm sensor, smoke detector and fire extinguisher providing us with information, which we never received by our previous service provider. The monitoring operators are understanding, even if the alarm is activated by mistake, the operator will still ask all safety questions and ensure all is OK. We are so glad we switched to Merrion and would highly recommend them to any Credit Union." Blaithin Bailey, Enfield Credit Union
