The theoretical uncertainties on the hadronic quantities that enter into the flavour physics precision tests of the Standard Model are, nowadays, at the (sub) percent level. For some of these quantities a better accuracy can only be reached by taking into account QED radiative corrections. This is possible by means of lattice simulations once a coherent description of electrically-charged states in finite volume has been provided. In this talk I will discuss the long-standing problem of charged particles on a finite volume from a general point of view and present a solution to the problem that does not violate the axioms of local quantum field theory. Then I will discuss a method to compute QED radiative corrections to hadronic decay rates.
