I'm not looking for quick payoff.Once things begin to show a resemblance of stabilisation, I would split it between an equity fund such as Vanguard 80% Equity and perhaps an oil ETF for a longer term perspective, and some sort of ISA where you can't access it for a while but you get an interest rate higher than inflation (hard to find now). You'd have to give much more info than just the amount though, such as timeframe, do you want quick access to it, what's your risk appetite etc.
