Quote (from the Government's website dedicated to the new legislation):
"Is this just about smoking in pubs?
No. Virtually all enclosed workplaces and public places, including offices, factories, restaurants, pubs, schools, public transport,
membership clubs and shopping malls are covered by smokefree legislation, meaning the enclosed parts of these places will become completely smokefree when the legislation is implemented on 1 July 2007."
