I've used Ronseal Wood Filler to fill a much bigger hole than that in a window sill. You can also get a liquid which helps to stabilise any surrounding rotten wood - paint that on first, and let it dry.

The hole in my sill was so big that I used offcuts of wood (which was meant to be kindling) mixed in with the filler to bulk it out.

I'm under no illusions that my bodge repair is anything permanent, but it will do until I have the windows replaced.

Thanks Ectophile, I read this out to DH, we're going to go with your plan rather than spend another tenner on expanding foam!
