British household electrical systems are normally built as one large ring circuit, originally in order to save copper after WW2.
This means you don't have breakers for each branch circuit (there are no branch circuits), just the single mains breaker for the house. This single breaker is too large to trip from a short from occuring in the smaller wires inside an appliance.
So each plug (or hardwired device) needs it's own dedicated smaller fuse instead.
