  Nowadays, one needs to consider seriously the possibility that a large
separation between the scale of new physics and the electroweak scale exists.
Nevertheless, there are still observables in this scenario, in particular the
Higgs mass, which are sensitive to the properties of the UV theory. In order to
obtain reliable predictions for a model which involves very heavy degrees of
freedom, the precise matching to an effective theory is necessary. While this
has been so far only studied for a few selected examples, we present an
extension of the ${\tt Mathematica}$ package ${\tt SARAH}$ to perform
automatically the matching between two scalar sectors at the full one-loop
level for general models. We show that we can reproduce all important results
for commonly studied models like split- or high-scale supersymmetry. One can
now easily go beyond that and study new ideas involving very heavy states,
where the effective model can either be just the standard model or an extension
of it. Also scenarios with several matching scales can be easily considered. We
provide model files for the MSSM with seven different mass hierarchies as well
as two high-scale versions of the NMSSM. Moreover, it is explained how new
models are implemented.
