Windlesham is a village in the Surrey Heath borough of Surrey, England and civil parish that covers Bagshot and Lightwater in the same borough. Its name derives from the Windle Brook which runs south of the village into Chobham and the common suffix 'ham', the Old English word for 'homestead'. A few large companies of late-20th-century origin have based themselves in Windlesham, including Rainbow Play Systems and the Linde Group.
