We present spectra of the Ultra-Compact HII region G29.96-0.02 taken with the SPIRE FTS on-board the Herschel Space Telescope. We detect the 12CO and 13CO ladder of lines and the [CI] line of neutral carbon. The FTS spectra are combined with ISO SWS and LWS spectra and literature fluxes to present a detailed spectral energy distribution (SED) of the source spanning three orders of magnitude. The quality of the SED longwards of 100 micron allows us to fit a grey body with an accuracy rarely obtained with previous instruments. The bolometric luminosity of the observed SED is coincident with that of the newly formed O-star that is powering the HII region.
