UK Tax allowance

Hi,
does anybody know what is the limit for not declaring goods bought in Japan when entering the UK?
and if you trespass that limit and they tell you to declare, how much you need to pay?
cheers

This question is better asked by contacting the Customs service in the UK:

# If you bring in something worth more than the limit of ��145, you must pay charges on the full value, not just the value above ��145.
# You and anyone you are travelling with cannot pool your individual allowances to bring in an item worth more than the limit. You will have to pay charges on the full value of the item.
# If you are bringing back any duty-free or tax-free goods you bought when you left the UK, these count as part of your allowance.

If you do not declare the goods in the red channel, you are breaking the law and we may prosecute you. They usually confiscate the goods.
