We present a new framework for calculating multi-jet observables through a resummation of hard emission. The framework is based on high-energy factorisation of amplitudes, with the region of applicability extended by constraining the behaviour of the scattering amplitudes according to other known all-order results. As an example of application we study predictions for Higgs production at the LHC in association with at least two jets through gluon fusion. The result is matched to the known tree level matrix elements for 2 and 3 jet final states, and implemented in a Monte Carlo generator. The technique is readily applicable to other multi-jet processes.
