Cash gift from India from parents

I am in UK with an ILR . I pay tax in UK . My parents want to bank transfer cash gift approx £14000 to help towards deposit for house . Wanted to know how much money is allowed to be accepted as gift through bank transfer . If it remains in bank for a certain time before a house is brought then do we have to pay tax on whole amount or only interest generated . Is it taxable if we keep the amount in cash ISA ,

Hi Harshal PATKAR
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
Tax on dividends
Individual Savings Accounts (ISAs)
Thank you.
