A non-perturbative renormalisation prescription for the energy-momentum tensor, based on space-Time symmetries along the Wilson flow, has been proposed recently in the context of 4- dimensional gauge theories. We extend this construction to the case of a scalar field theory, and investigate its numerical feasibility by studying Ward identities in 3-dimensional scalar field theory. After introducing the Wilson flow for the scalar field theory we discuss its renormalisation properties and the determination of the renormalisation constants for the energy-momentum tensor.
