Leiston’s High Street serves as the business and market hub of the surrounding agricultural district. The town’s facilities include a post office, library, banks, pubs and a range of shops and other services. Leiston Film Theatre, a half-timbered building with street-front shops, is the oldest purpose-built cinema in Suffolk. The cinema is owned and run by Leiston-cum-Sizewell Town Council and backed by Leiston Film Theatre Support Club, which has raised money for stage refurbishment and enabled the cinema to install a digital 3D projection system.
