We apply a joint Renormalised Perturbation Theory and Numerical Renormalisation Group approach to the study of an n-orbital Anderson Model with a Hund's Rule Coupling. We apply the same methods to the analysis of a two-impurity Anderson model, and find the emergence of a single renormalised energy scale on the approach to two types of quantum critical point, such that it is possible to characterise the low energy physics in terms of this energy scale alone.
