The vast majority of underage drinkers first sample alcohol at home rather than in a pub, according to new government research.
A study of 4,000 adults and children by the Department for Children, Families and Schools revealed that half of young people who have drunk alcohol were given it by their parents.
Only 17 per cent of the youngsters quizzed said they drank at a pub, with 11 per cent saying they drank at a club or a disco.
When asked about their behaviour over the past week just over one in seven of young people claimed to have had a drink.
This compares with nine per cent of children overall who said they drink at least once a week.
The publication of the research coincided with a government announcement about plans to tackle underage drinking including extra police powers, a best practice guide and a national football tournament.
The government also wants parents to be more proactive in educating children about alcohol.
Schools minister Vernon Coaker said: "Today's research shows that parents underestimate their influence over their child's drinking and attitudes to alcohol, yet a quarter of young people have never spoken to their parents about the issue.
"That's why through the 'Why Let Drink Decide?' campaign we are giving parents and young people the confidence to have open conversations about alcohol, to ultimately delay the age at which young people start drinking.
Alcohol awareness charity Drinkaware boss Chris Sorek, said: "Children need to know the facts about alcohol and often parents are in the best position to give it to them."
