Royal Mail typically delivers mail and parcels from around 7 am to 3 pm in most urban areas Monday to Saturday, with rural deliveries sometimes extending until 4 pm or slightly later. While the standard delivery process generally stops after 5 pm, some tracked or special deliveries may arrive later in the evening, sometimes as late as 7 to 9 pm at the courier's discretion. Royal Mail does not officially guarantee deliveries after 6 pm but occasional later deliveries can occur depending on driver schedules and local circumstances. Deliveries do not normally happen on public holidays, though some services like Special Delivery Guaranteed may have specific options including early morning deliveries by 9 am the next working day or Saturday deliveries. Sunday deliveries are limited to certain areas and service types. Overall, the majority of normal deliveries will be completed by mid-afternoon to early evening at the latest.
