What time do Royal Mail deliver packages?

Royal Mail do not deliver on a Sunday. Deliveries are only made Monday to Friday, with a reduced service on Saturday.

All mail for any given street / district handle by the assigned postman - who is responsible to ensure delivery of all mail to that round. Letter mail is their priority and parcels or packets go in the bags after the letters. If there are any parcels / package that too big, bulky or heavy to fit in the bag

All mail for any given street / district is the responsibility of the postman assigned to the round. He is required to ensure delivery of all mail to that round. However, letter mail is his priority though, so parcels and packets go into the sacks after the letters. If there are any parcels or packets that are too big, bulky or heavy to fit in his sacks, he can pass it to a driver who will cover several postmen's rounds and deliver the over-sized or overweight items, plus letter mail to any business or premises that regularly receive large quantities of mail. Whether it comes by van or postman really depends on the size, shape and weight of your item, and if its relatively small and light, it depends on how busy your postman is and how full his sacks are. Please be aware that there might be two deliveries a day (don't worry if its not with the first)!

Van or postman, either way, it ought to be delivered by 3 PM if its coming at all that day. It is possible to be later than this, but it will be because your local office is short staffed and another postman is doing it on overtime after his own round, but this is uncommon.

There can be no set parcel delivery time, because of the nature of the job: As not every address gets mail every day, and the route taken varies with the weight of the sacks and the individual postman. The same goes for the drivers, so you can't be sure of an exact time, just that it will be between 9 am and 2 pm on a weekday, and about 8 am and 12.30 pm on a Saturday.
