Anyone know a simple way of calculating the second moment of area for an L shaped object, a formula would be good, or some method to work it out.

and that would give me the total area then, and not the second moment of area

split the L into two so its 2 rectangles then measure legnth and width of both and add the 2 areas together.

You need to use the parallel axis theorem. Find the neutral axis for the L shape. Split it into two rectangles, work out the I for the first rectangle and add the area x distance from neutral axis squared then repeat for the second rectangle and add both together.
