A town shaped by its airport neighbour
Gatwick Airport lies just south of Horley, and the town's growth through the twentieth century has been closely tied to the airport's own expansion, bringing housing development alongside the older centre around Horley's high street.
Briefly moved, then returned to Surrey
A local government reorganisation in the 1970s temporarily placed Horley within West Sussex, but local opposition led to it being returned to Surrey soon after, leaving the airport itself just across the county line.

Planning through Reigate and Banstead
Horley falls within Reigate and Banstead Borough Council, the same authority responsible for Reigate, despite sitting some distance to the south of it.
