Historically, it was in the parish of Newport Pagnell but today it is separated from Newport Pagnell by the M1 motorway and has become part of Milton Keynes. Just a few farms remained before the land was built on. It is now an industrial area.
Numerous companies operate from Tongwell such as Dawson Group, Mercedes-Benz UK and Volkswagen UK.
