By late December of this year I will have £2000 to invest. What’s the best option.

I know that is not a crazy amount to invest for me it’s a start. I want to invest in something that isn’t a scam and is reliable. And I know this sounds typical but I don’t want to have it sit there for 5 years to get like £200 profit. I want something that’s worth putting money into, is reliable and won’t take ages for little to no pay off. Any help would be appreciated greatly :)
