The Office for National Statistics (ONS) calculated that the average UK price for a packet of 20 king size cigarettes was £12.77 (December 2022) which works out at £4,661 per year for a pack-a-day smoker.
By comparison, it is estimated that a vaper (who has totally switched from smoking) could expect to pay roughly £400-700-a-year on vaping, resulting in a saving of around £4,000-a-year.
In fact, according to an August 2022 ASH (Action on Smoking and Health) report, saving money was the second most common reason given by current smokers for choosing to switch to vaping (16%) with cutting down on smoking cited as the main reason (17%).
