Quality of Service


Royal Mail's regulatory conditions require us to measure quality of service from handover to Royal Mail at inward mail centre's through to the final delivery address. Measurement is carried out by an independent research company using a combination of posting and recipient panelists and Radio Frequency Identification (RFID) devices.
