This film is rated PG by the British Film Classification Board. Below is their reason for this rating.
PADDINGTON 2 is a comedy adventure sequel in which Paddington Bear gets into unexpected trouble when he attempts to buy a very special birthday present.
There are scenes in which Paddington is rescued from drowning, first as a cub as he floats on a log heading for rapids, and then when he is trapped in a train carriage that has fallen into a river. Although there is some tension and a sense of danger in both scenes, this is quite brief and the outcome is reassuring. There are also scenes of comic threat, played as slapstick, with characters attempting to cross from one moving train to another or making escapes along the top of trains, and Paddington facing the displeasure of prison inmates. The outcomes are all, once again, reassuring and no-one comes to any harm.
There is a scene in which a story is being told of a trapeze artist who fell to her doom after her equipment is sabotaged. The scene is very brief and without details of injury.
There is also very mild slapstick violence with fairground props, including floppy swords and a gun that fires plastic darts, being used as ineffectual weapons.
There is also a comic scene in which Paddington uses a pair of electric toothbrushes to clean his ears, nostrils and teeth.
There is infrequent use of very mild bad language such as 'bottoms' and 'oh my God'.
