The Health Survey for England has revealed that 225 million litres of alcohol go unaccounted for each year. This amounts to drinkers in the UK consuming the equivalent of a bottle of wine per week more than they admit.
The figures also showed that 41% of men and 32% of women had consumed more than their recommended number of units of alcohol on at least one say in the previous week.
This includes 25% of men and 15% of women who had drunk more than twice the recommended maximum, which is 14 units a week for women and 21 units a week for men.
A Department of Health spokesperson said: “Many of us enjoy a drink, especially at Christmas, but too many people in the UK regularly drink more than is safe, often without being aware of it.
