More than 300 made redundant
The business is based at Heathfield, near Newton Abbot and also has a site in Yorkshire and is the UK's largest manufacturer of ceramic wall and floor tiles.
313 people have been made redundant and 67 employees will stay on to help wind down the business.
Joint administrator Andrew Sheridan said: "British Ceramic Tile Limited is a leading player in the manufacturer of ceramic tiles, with a long-standing heritage in the local communities in which it operates and a stellar reputation for its quality products. Unfortunately, challenging trading conditions and the termination of a key customer contract in recent days have forced the business to enter administration and cease trading with immediate effect. We are currently providing support to the affected employees and are working closely with the Redundancy Payments Service to ensure the best possible outcome in this difficult period."
