In several years with LOWW as a homebase I have never heard progressive taxi instructions nor the rather useful "follow the green" that Heathrow uses (or used?). Expect to be sent over to Ground (121,6 or 121,775) after vacating, then depending on general traffic level it may take more or less time to get through to the GND controller. You will get a taxi clearance that may be straight-forward or involve stopping at various holding points, swerving between parallel taxiways via a multitude of exits between them, holding short clear of an exit or two and the like. Having a pencil and a map ready will be very helpful, as some controllers do not seem to particularly like repeating their clearance.
Some first-time visitors mistake the 3 yellow lights at M2 or L2 (these are the handover points between the two GND frequencies during times of heavy traffic) for active stop bars and stop there also when not instructed to do so. This will draw a frown from GND. The real stop bars on the taxiways use red lights; those will always be off when You are cleared to cross them but may or may not be switched on when You are to hold short.
