There is no age limit to buying lighters. You can be 2 years old to buy one HOWEVER, it is the stores decision to sell it to you. You have to be 18 to buy butane products, and lighter fluid, BUT, lighters such as the average BIC don't use butane. There is a law stating you cant sell cigarette paraphernalia to minors, and lighters don't fall under that category. So, basically there is no age limit to buying lighters in the UK.
