We present the average pressure profile of 461 galaxy clusters from the 2500d South Pole Telescope catalogue measured in the Planck and SPT-SZ data jointly. The joint measurement is performed in Fourier space for the first time, and takes advantage of the complementarity between the high resolution of SPT (1.75 arcmin beam) and the coverage of large angular scales by Planck (> 30 arcmin). The redshift leverage of the catalogue allows the study of the evolution of the profile. We also constrain the profile shape in the outskirts.
