With plenty of news out about parcel delays and mail strikes a lot of businesses will have had appropriate concerns over important business deliveries and how a lost parcel or significantly delayed one could reflect poorly upon them. This is why large parcel delivery services are the preferred choice for businesses of all sizes.
The kind of parcels being sent by large companies and businesses are typically much more sensitive than those being sent between family members, a decent level of security is hoped for as many business parcels or letters will include sensitive data or even confidential financial data which your company will definitely not want to get into the wrong hands.

Parcel Couriers are the better choice as they are not only more secure than the national postal service but they are quicker thanks to a less burdened mailing network complete with dedicated secure delivery vehicles and many companies having their own fleet of aircraft able to handle deliveries internationally.
As well as being more secure and quicker parcel couriers are more flexible with regards to what you can actually send, the Royal Mail has restrictions on parcels which is done to classify the size and how expensive it will be to send.
Couriers are able to handle larger and even abnormally shaped items and take greater care over them. Common parcel businesses send is poster tubes containing blueprints, artwork or any other large graphics and so this tube would be a difficult item to send unless you chose a dedicated parcel courier service to handle your important delivery.
