VIDEO: What happens after you post a letter?

Have you ever wondered what happens to your post after you pop it into the red letterbox?

The state-of-the-art sorting centre represents a £27million investment by the company, and has been at the Maxted Road site on the Maylands Avenue industrial estate since spring last year.

Three million items of mail are also sorted per day in the huge warehouse, which deals with letters, packages and parcels from across the UK, including Scotland and Wales. Many of the items that come in are manually sorted into different sections of the warehouse before being taken out for delivery.

Most of the people employed at the centre are parcel sorters, as parcels are the main growth area of the business due to the rise in popularity of internet shopping. The centre sees an average of 350,000 parcels pass through over a 24 hour period.

Much of the letter sorting is done using specialised automated machinery, but these are monitored on screens by staff who aim to sort around 40,000 letters an hour.

Delivery offices previously in Berkhamsted, Stevenage and Watford all began relocating to the new site in August 2011 on a phased basis and now operate under one roof in Hemel Hempstead.
