Neutron electric dipole moment (nEDM) experiments require precision magnetometry to correct for systematic effects due to magnetic field fluctuations. I discuss the options for such magnetometers and present details of a 12-SQUID magnetometry system constructed for use in a cryogenic nEDM experiment. This has been developed to operate in 0.5 K superfluid helium and installed and tested in apparatus at the Institut Laue Langevin, Grenoble. The system is designed to track fields at the 0.1 pT level, consistent with a proposed experimental limit on an nEDM of $d_n \sim 10^{-27}\,e$cm.
