How can I go about recreating this with a procedural material. It's part of a comission and it needs to have seemingly randomly scattered spots of slightly different sizes and colours on a white surface.
Node set ups would be much appreciated!

It's quite simple node setup so I don't know if it needs explanation:
You could pass the upper Voronoi's Color through a color ramp to define your own colors, or you could connect it to Hue inside Combine HSV node to have all circles with very intense and bright colors.

$\begingroup$ This is great, thanks so much, excuse my node naivety but where can I find the scale, circle size and randomness nodes? $\endgroup$ Commented Jul 14, 2021 at 16:25

1$\begingroup$ Those are all just Value nodes that you find in inputs when you add a node. The OP simply changed the labels on the nodes to make them clearer. $\endgroup$ Commented Jul 14, 2021 at 20:21

Try something like this. Just take the inverse of some 2D Voronoi dots (Clamped with a ColorRamp) with the randomness turned down, then multiply it by the colors from the Color Output, then invert it again:
