In this talk, I will first give a short introduction to post-Lie algebras and briefly explain how they can be used to build the structure group for quasi-linear SPDEs in the context of regularity structures, then I will present my last results concerning geometric deformations of post-Lie algebras and possible applications to the theory of regularity structures for the renormalisation of SPEs.
