BS1363 plugs are joyfully oversized, yes (and make excellent caltrops if dropped) but they are in other ways excellently engineered. Inherently polarised, fuses to protect the appliance wiring[0], socket shutters that open on the earth pin only to prevent vigorous insertion of metal by children, sleeved conductors to avoid shock when partially inserted, essentially unbendable...

Plus, I will fight anyone who suggests that 1400W is enough for a decent kettle ;-)

[0] Admittedly this was mostly included to offset the idiosyncrasies of final ring circuit wiring, but it's still better than just a big breaker.
