Abstract : Since their discovery as VHE emitters by H.E.S.S. in 2004, the high-energy peaked BL Lacs PKS 2005-489 and H 2356-309 have been monitored at VHE to study their flux and spectral variability. To sample their SED, several multiwavelength campaigns with X-ray satellites have been performed, showing important spectral changes. Here we present the results of 3 years of H.E.S.S. observations together with multiwavelength data, in the context of the SED evolution and in comparison with the historical states.
