Watford Gap services are motorway services on the M1 motorway in Northamptonshire, England. They opened on 2 November 1959, the same day as the M1, making them one of the oldest motorway services in Britain. The facilities were originally managed by Blue Boar, a local company that had run a nearby petrol station before the M1 opened. Roadchef bought the services from Blue Boar in 1995. The services are named after the nearby Watford Gap, a crossing point of the limestone ridge just north of the village of Watford; the name is unrelated to that of the town of Watford in Hertfordshire.
