After a short motivation for non-minimal SUSY models, I will introduce a framework to study BSM models using the Mathematica package SARAH. In particular the interface between SARAH and SPheno is discussed. It is shown that this combination of codes provides a high precision and flexible spectrum generation for a wide range of models. This functionality has been extended in the last year by an automatised two-loop Higgs mass calculation. The methods and assumption used in these calculations are explained, and an outlook to future improvements is given. I will also discuss results for important corrections in the NMSSM in the large lambda limit which have been calculated for the first time with this setup.
