Sorting & Dispatch

Although the Langley HWDC is manned, it is one of the most automated sorting centres for the Royal Mail in the UK. The site for Langley HWDC covers over 20 acres of land, all of which is utilised for sorting and dispatching mail across the UK and around the world.

Conveyor belts are used a lot on site, with machines able to scan codes on parcels and sort packages into their designated sections of the giant warehouse. Cameras are also used to sort out parcels and letters to their designated sorting pile, something which is hardly used in other Royal Mail sorting centres in the UK.

If mail is being transported out of the country via air travel and is fragile/oddly shaped, it is sorted into manual piles for manual loading onto aeroplanes and other means of travel. If you have tracking on your parcel, you can view exactly where your parcel is online with the Royal Mail parcel tracking website.


Delivery Services

All outbound international mail is handled at Langley HWDC. Although international delivery is hard to organise, the Royal Mail offer services that rival any other company offering fast international delivery. Items to Europe will take roughly 3 – 5 days, and countries outside of the EU (such as Australia and the US) will take longer. If you are sending parcels to countries outside of the UK, you will be given a window of time in which your items will be expected to arrive.

To send mail overseas, the price is considerably higher, and is designated by weight. You can check how much a parcel may be to send by heading over to the Royal Mail website. You may find that you can pay for your parcel online and print out a delivery label for you to stick onto your parcel yourself.


Prohibited Items Helpline

Although the Royal Mail are very lenient with what you can send both within the UK and around the world, there are items are prohibited from being sent via their sorting centres.
