Last year our Priority letters service was suspended and our Regular letter services changed in response to COVID-19. These changes expired on 30 June 2021. From 1 July 2021, we’ll endeavour to deliver according to delivery timetables as best we can while the ongoing challenges of COVID-19 remain.

For most of our bulk mail services, customers can choose between two delivery speeds: Regular or Priority.

Please see the following delivery timetables:

Some of our services require you to sort your mail to benefit from the best possible postage discounts. We can help supply you with mail trays, sort plans and mail tray labels.

Barcoding is also a requirement for some bulk mail services. It helps us process it more efficiently - meaning cheaper postage rates for you. Find out more about barcoding.
