The Health Act 2006 is a large Act with several different parts. For most ordinary businesses, the section with the clearest operational impact is Part 1, headed Smoking. The contents page shows that this part deals with smoke-free premises, smoke-free places, vehicles, no-smoking signs, offences, fixed penalties, enforcement and interpretation.
The Act is not just about smoking. It also includes parts on prevention and control of healthcare associated infections, controlled drugs, medicines and pharmacies, pharmaceutical services, ophthalmic services, NHS fraud, audit, appointments and other miscellaneous matters. Those parts are more likely to matter to regulated health-sector operators than to a typical SME.
That means the Act has two very different kinds of business impact. For most employers, retailers, venues and service businesses, the practical focus is smoke-free compliance in England. For healthcare and pharmacy operators, the Act may also affect regulated services, medicines handling, pharmacy premises and sector-specific enforcement powers.
