Hypnotism
You must hold a permit, under the Hypnotism Act 1952, to stage a public performance of hypnotism for entertainment purposes - whether live or broadcast. You won’t need a permit if the hypnotism is for the purpose of scientific demonstration or research, or if you are only hypnotising yourself.
"Hypnotism" includes hypnotism, mesmerism and any similar act or process which produces or is intended to produce in any person any form of induced sleep or trance in which the susceptibility of the mind of that person to suggestion or direction is increased or intended to be increased but does not include hypnotism, mesmerism or any such similar act or process which is self-induced.
Permits can be obtained by applying to the local authority within which the performance premises is located.
If you stage hypnotism for entertainment purposes without a permit or break any of the conditions on your permit, you could be fined up to £1,000.
