            The Daresbury SRS is a second generation synchrotron
            radiation source which ramps from its injection energy of
            600 MeV to 2.0 GeV. Beam orbit feedback systems have
            been in routine operation on the SRS since 1994 and are
            now an essential element in delivering stable photon
            beams to experimental stations. The most recent
            enhancements to these systems have included the
            introduction of a ramp servo system to provide the orbit
            control demanded by the installation of two new narrow
            gap insertion device and development of the vertical orbit
            feedback system to cope with an increasing number of
            photon beamlines. This paper summaries the current
            status of these systems and briefly discusses proposed
            developments.
