Returning to UK after many years overseas as a British citizen

I have some savings that I will need to use for buying accommodation in UK and living expenses. If I deposit it in a bank account in UK do I have to pay taxes once I get to the UK? If not, is there a limit on the time I am in the UK before I must deposit it before any taxes are required?

Hi,
You wont pay tax on the capital but any interest that this then generates is taxable income.
Thank you.
