The WITCH experiment aims to study a possible admixture of a scalar or tensor type interaction in beta decay by determining the beta-neutrino angular correlation from the shape of the recoil energy spectrum. The experimental set-up couples a double Penning trap system to form a scattering-free radioactive source and a retardation spectrometer to probe the recoil ion energy. The intensive commissioning of the set-up is ongoing at ISOLDE (CERN). The layout of the WITCH set-up and results of commissioning tests performed until now will be presented. Results of the data taken during 2006 (two beam times with 124In) will be shown as well, presenting the first recoil ion spectrum obtained. Finally, perspectives of the physics program will be discussed.
