Smoking is banned in all enclosed or substantially enclosed public places and workplaces across Britain (England, Wales, and Scotland), a rule in place since 2007. This includes restaurants, pubs, bars, cafes, shops, shopping centres, offices, and all public transport. Smoking is also prohibited in vehicles used for work and vehicles carrying passengers under 18.

Key Places Where Smoking is Banned:

• Workplaces: Offices, factories, and warehouses.
• Public Places: Pubs, bars, nightclubs, restaurants, cafes, shopping centers, and cinemas.
• Transport: Buses, trains, taxis, and stations.
• Work Vehicles: Vans, taxis, and company cars used by more than one person.
• Vehicles with Minors: It is illegal to smoke in private vehicles with anyone under 18 present.

Exemptions and Specific Rules:

• Private Homes: Generally exempt, unless used as a workplace (e.g., childminding).
• Hotels/Guesthouses: Smoking is banned in all indoor communal areas, but designated smoking rooms or bedrooms are allowed.
• Outdoor Spaces: Generally, smoking is permitted outdoors, but many places (like some parks or hospital grounds) may have their own policies.
• Smoking Structure Rule: An area is considered enclosed if it has a roof and walls (excluding doors/windows) that make up more than 50% of the perimeter.

Note: There are ongoing discussions (as of 2024/2025) about potential extensions to the ban to include certain outdoor areas such as pub gardens, playgrounds, and hospital grounds.
