There is an annual exemption, that allows an individual to give away a total of £3000 worth of gifts each tax year without them being added to their estate.
You can give gifts or money up to £3,000 to one person or split the £3,000 between several people.
You can give as many gifts of up to £250 per person as you want each tax year, as long as you have not used another allowance on the same person. You can see further guidance here:
