Results are presented on a number of searches for new physics in ep collisions at HERA using the ZEUS and HI detectors. Limits are presented on the production of elicited fermions, contact interactions, as well as a heavy right handed neutrino and W-R boson. Also presented are ZEUS results on the excess of events at high x and Q(2).
