The search for the neutron electric dipole moment (nEDM) has a long history in constraining theories of CP violation. A number of efforts around the world aim at improving the sensitivity of this search by another order of magnitude or more. At the Paul Scherrer Institut (PSI) we have built a new high intensity source of ultracold neutrons (UCN) and, within an international collaboration, set up a nEDM experiment which is just entering its data taking phase. A next generation experiment called n2EDM is being prepared at the same time. Along with the motivation and the international context, I will discuss production and use of UCN and the nEDM experiment at PSI.
