A retained service agreement means iPower takes ongoing responsibility for the maintenance of your generator on a contract basis. Depending on scope, this covers: scheduled servicing at defined intervals, emergency call-out response with agreed response times, consumables supply (oil, filters, coolant, belts, batteries), load bank testing, ATS functional testing and documentation, and a full asset management record. For life safety facilities, we tailor the agreement to fully satisfy BS 8519 operational and testing requirements.
