Gift from grandmother from abroad

Hello, my grandmother wants to gift me $20-30k from the US. She is not a UK resident, but I am. Will there be any taxes involved in this transfer?

Hi

There are no income tax implications on the receipt of a cash gift unless the cash gift generates interest or dividends.
These would then potentially be subject to tax. Further guidance can be found here Tax on savings interest and Tax on dividends 

Thank you
