Radiative kaon decays are extremely relevant modes in the search for physics beyond the Standard Model, as well as to learn about the Standard Model itself below the confinement scale. The field experienced a vigorous boost due to the scientific programs started by KTeV and NA48 more than 20 years ago. In this write-up I will focus on the potential of the radiative kaon analyses to be performed at NA62 and LHCb to constrain further the Standard Model at low energies.
