  Results of a general search for new phenomena at high transverse momentum and
of a dedicated search for events with isolated leptons and missing transverse
momentum are reported. These searches were performed on a data sample collected
at HERA in e+-p collisions with the H1 detector in the period 1994-2004. The
results obtained in the isolated lepton search are compared with those obtained
by the ZEUS collaboration in the period 1994-2000 and limits on the anomalous
FCNC production of single top events are presented.
