No smoking signs are a legal requirement in the UK. Smoking in enclosed places was banned in the United Kingdom on the 1st of July 2007. We recommend that you display no smoking signs at each entrance of a smoke-free public building or workplace. The no smoking signs in this category will implement the no smoking law on your premises and will ensure your visitors or employees do not smoke on site to avoid any hefty fines or prosecutions. All no smoking signs are manufactured using high-quality external grade sign materials so they will last for many years to come.
