In the search for new fundamental forces and constituents of matter, we will have to look for small deviations from the standard model in the coming years. As the windows for new physics shrink and no candidate for new physics emerges, automated precision tools become indispensable for studying Beyond Standard Models (BSM) at particle colliders. In my talk I review the technology used by the community to automate the computation of next-to-leading order amplitudes in UV complete models and effective field theory. I will discuss obstacles in the automation of UV complete models using the example of renormalization of mixing angles. Finally, I conclude that although BSM EW renormalization is not trivial, automation of EW corrections can be achieved for a large class of BSM models.
