To the north of Pitsea is the Burnt Mills Industrial Estate which has many industrial units, including freight delivery, printing, a car wreck yard and a small amount of manufacturing, including Gardner Aerospace. Also in this area is the main delivery depot for the courier T.N.T.. The area also has the main sewage treatment works which during the summer has reportedly been the cause of a nasty stink, although Essex and Suffolk Water deny there is anything wrong with it. Also further along from there is the main local depot for the cable TV company Telewest Blueyonder, which came to the area in the early 1990s under the name of United Artists before changing its name to Telewest and then more recently to Virgin Media. This previously had been the main customer service centre for United Artists.
