We present a systematic approach to the classification of the UV properties of higher dimensional operators spanned by $\Phi^\dagger \Phi$ and ordinary derivatives thereof (e.g. $\partial_\mu (\Phi^\dagger \Phi)\partial^\mu (\Phi^\dagger \Phi) , (\Phi^\dagger \Phi)^3, (\Phi^\dagger \Phi)^4, \dots$) in Higgs Effective Field Theories. The procedure is purely algebraic and thus regularization-independent. It relies on a novel set of hidden symmetries that can be formulated in an extended field space where the singlet $\Phi^\dagger \Phi$ is treated as a dynamical variable. The resulting relations stemming from such symmetries are valid to all orders in the loop expansion. Several applications to one-loop processes are considered.
