Pay in £500 and then £100 pm.
So in a year you pay in £1700.
Quidco = £170 (very good tracking reliability).
Their fees are small (just short of 1%) so obviously whilst stocks and shares can go up and down a starting position of 9% is in my view incredible.
You get to choose the risk (I went for the 4th risky "growth").
Their website is very easy to use and they seem to have lots of positive feedback.
They have a more expensive 'fully managed' account but this is more expensive (not by much).
