Abstract The H1 experiment has reported an excess of events with an isolated lepton, missing transverse momentum and a high E_T hadronic system. The kinematics of these events are mostly compatible with a leptonic W decay. Here we investigate W production in the jet decay channel. Using an integrated luminosity of 117 pb^-1, jets are selected using the inclusive k_T algorithm with a minimum transverse energy of 25 GeV. The phase space has been optimised to maximise the acceptance for W events and to reject other Standard Model processes. The data is compared to QCD expectations and an upper limit on the W cross section as a function of the E_T of the hadonic system excluding the W is established.
