We report the final results of the search for gravitationally lensed flat‐spectrum radio sources in the 2384‐source Jodrell Bank–VLA Astrometric Survey (JVAS). We describe the process of selecting candidate lensed sources from 8.4‐GHz VLA snapshot maps. 66 sources were selected as lens candidates and were followed up with multifrequency VLA and/or high‐resolution MERLIN 5‐GHz observations. To illustrate the candidate elimination process, we discuss examples of sources representative of particular morphologies that have been ruled out by the follow‐up observations. There are six gravitational lens systems in the JVAS, five of which are new discoveries. We summarize the properties of all the systems.
