Here is section 182 of the UK Copyright, Designs and Patents Act, 1988:

a performer's rights are infringed by a person who, without his consent—

1. makes a recording of the whole or any substantial part of a qualifying performance directly from the live performance,


2. broadcasts live, the whole or any substantial part of a qualifying performance,


3. makes a recording of the whole or any substantial part of a qualifying performance directly from a broadcast of, the live performance.

In an action for infringement of a performer's rights brought by virtue of this section damages shall not be awarded against a defendant who shows that at the time of the infringement he believed on reasonable grounds that consent had been given.

Seems pretty clear. If you don't have permission it's not lawful in the UK.
