I'm not from UK so can't answer that. But if you think logically, there are some things you can't do in apartment, e.g. listen to loud music at night, or drill holes when others might be sleeping. Turning down heating to zero is one of them. AFAIR in some places there is a limit of how low your heating should be and if it is lower then you still pay a given set price - this is to discourage cheaters.
