Note that the quantities shown in ubasses’s link are not “Duty Free” allowances. Since 1999 there have been no DF allowances for travel between EU countries. You may bring in as much tobacco or alcohol as you wish providing tax/duty has been paid in the country of origin, you transport them yourself and that the goods are for your own use. However, HMRC has set down guideline amounts beyond which they will question you closely about the reasons you have the goods and these quantities are those shown in the link
