The 714's operation within the Greater London area (London Borough of Barnet will be under a London Service Permit, which Metroline also have for route 84 (New Barnet to St Albans). The 84 was the last route operated under a London Local Service Agreement, and for many years was a bit of an anomaly, a former 'red' bus route operating predominantly outside the Greater London area, and still retains the number within the TfL numbering system, although in theory TfL could reuse the number elsewhere. The 81 to Slough, always a 'red' bus route and still tendered by TfL is now perhaps the next most anomalous, although some might cite the incursion into Leatherhead in Surrey too.
