Although Iāll note (because none else has) that the real reason you shouldnāt actually do this, isnāt electrocution risk - but rather that UK āring mainsā circuits are often 35A and rely on the Type G plug having a lower value fuse (3A, 5A, or 13A) to prevent all of that being drawn (and starting a fire) in the event of a dead short in the appliance.
