This document discusses where to keep cash if one were to inherit £100,000. It notes keeping it at home has advantages of easy access but disadvantages of risk of theft, loss, or aimless spending. A safer option is a savings institution like a bank or building society. These offer various deposit and savings accounts that pay interest. The interest income is taxed, with a personal savings allowance exempting the first £1,000-£500 of interest depending on tax bracket. Cash deposits provide benefits like interest, protection up to £75,000, and liquidity, but also risks like institution collapse, inflation eroding returns, interest/exchange rate changes.
