Events with high energy isolated electrons, muons or tau leptons and missing transverse momentum are studied using the full e+- p data sample collected by the H1 experiment at HERA, corresponding to an integrated luminosity of 474 pb-1. Within the Standard Model, events with isolated leptons and missing transverse momentum mainly originate from the production of single W bosons. The total single W boson production cross section is measured as 1.14 +- 0.25 (stat.) +- 0.14 (sys.) pb, in agreement with the Standard Model expectation.
