We prove a locally uniform lower bound on the density of states of continuum random Schrödinger operators in the localised regime. The main technical ingredient is a new bound on the expectation of the spectral shift function for random Schrödinger operators in the localised regime, corresponding to a change from Dirichlet to Neumann boundary conditions along the boundary of a finite volume. The bound scales with the surface area. (Joint with Adrian Dietlein, Abel Klein, Peter Hislop, Peter Müller)
