As from the 1st October 2015 Under the Children and Families act 2014 you have to be over the age of 18 years old to purchase e-liquid and electronic cigarettes.
Due to the new regulation companies selling e-liquid need to be able to prove that their customers are over the age of 18. There are a couple of ways to check someone's age. First is by asking customers to upload photo identification via email etc. This method is used by a wide range of industries such as gambling websites. These sites also use Age Verification companies to perform automatic checks the same as we do.
We perform the check only once when you create an account, via a company called GBG to validate your age. They check information from various sources, such as the electoral roll register, birth index data, GB driving licences and credit activity data.
Our check leaves what is called “a soft footprint” meaning that nobody other than yourself will be able to see the check. The check only leaves a soft footprint so that you know that the check has been performed. These checks are quite common for ID checks and you also get them when you apply for insurance cover etc. This check is not a credit-application search (Hard Footprint) so it does not affect your credit score. Here is a quick article from thisismoney.co.uk with more info on soft footprint checks.
