Under generic circumstances, the Standard Model Higgs is excited in the form of a condensate during or towards the end of inflation. The Higgs condensate is then forced to decay afterwards -- due to non-perturbative effects -- into the rest of the SM species. I will present the cosmological implications of this primordial decay, quantifying the necessary conditions to achieve a successful mechanism for ``reheating'' the Universe into the SM. If there is enough time, I will also discuss the implications of all this for primordial gravitational waves.
