Is a fire door closer needed?

[Guest Oliver]

Can someone tell me if a fire door designed to be kept locked shut requires a door closer to be fitted such as in a small laundry room in an educational establishment which is occasionally used by educational sraff but kept locked the majority of the time when not used to prevent children accessing the room.

Infrequently occupied cupboards designed to be kept locked shut don't have closers but rooms usually do, especially high risk rooms like laundries.
