A measurement of the integrated luminosity at the ep collider HERA is presented, exploiting the elastic QED Compton process ep - GT e gamma p. The electron and the photon are detected in the backward calorimeter of the H1 experiment. The integrated luminosity of the data recorded in 2003 to 2007 is determined with a precision of 2.3%. The measurement is found to be compatible with the corresponding result obtained using the Bethe-Heitler process.
