Have you tried looking at the below link - seems like that might do what you want

You can set the color range of each subplot to be equal and then add a colorbar only to one of the plots. Then change the colorbar position.
caxis(ax,[min,max])
Where ax is an axis handle and [min,max] is your color range.

This is fine but surely it would make the subfigure to which it is applied a smaller window than the others?

By default, yes. That's why my answer suggests to change the colorbar position which would change the subplot back to it's standard size. Here's a demo for you to run
figure()
h = arrayfun(@(i)subplot(1,3,i),1:3);
cb = colorbar(h(end))
% After executing this line below, subplots will be same size.
cb.Position(1) = .93
