Chesco is a general goods shop owned by Chesney Karib, located on Causweway Parade in Chatsworth. The shop was originally run by Kash and Yvonne Karib, parents of Chesney, it was called 'Karib's Cash & Carry' during this time. It spent a brief stint in Series 7 as the property of Joe Pritchard and was called Joe's Shop. Sometime between Series 7 and Series 8, Chesney's grandfather bought the shop to add it to his large empire of general good stores. In Series 9 Chesney turned the back room into a pawn shop, presumably both to help and capitalise on his neighbours recent evictions and desperation for money. At some point prior to Series 9 the shop began offering a video rental service.
In Episode 9 of Series 9, Chesney was shocked to discover his grandfather had ordered his cousin to clear out the shop, sell it and then send Chesney away to run a shop in another part of the country. Spurred by a recent near death experience, Chesney decided to try and buy the shop himself. He appealed to the Maguires for help but changed his mind when Jamie wanted the shop named 'Paddy's Market' after his father. An offer was later made on the shop, with Chesney having no money left after buying all the shelves and fittings he assumed that was the end of his dream. However, his cousin revealed he was going to sign the deeds over to Chesney, despite how their grandfather would react. Many of the residents then arrived to help Chesney paint and organize the shop, which he renamed 'Chesco'.

Which finally happened in Episode 716.
