Looking for no smoking signs? Since the no smoking ban came into effect in 2004 it has been illegal to smoke in the workplace and many public areas. Sometimes however people forget, and smoke in places they are not allowed to. A no smoking sign strategically placed can stop smokers from lighting up where they are breaking the law. In some instances you may wish to stop smokers congregating outside your premises, and again our no smoking sign range will offer a gentle reminder. You can choose from signs with graphics only and signs that combine text and graphics.
