NATS is busy switching off the NDBs as fast as the CAA will let it. As en-route procedures using the NDB are removed/RNAV'd the entry for that beacon is taken out of the en-route section of the AIP. Several of them are still included in airport procedures in which case they have been moved from the en-route listing to the listing for the relevant airport(s). That of course makes it next to impossible to find out whether or not an NDB is still in service without searching through the entry for any airport that might be nearby. The same will increasingly start to apply for VORs.
WCO was a part of Cranfield procedures, if it's gone from their AIP entry it's probably switched off. CHT and HEN still feature in some airport procedures which is why they are still switched on. For some reason they followed a different approach for WOD and marked the en-route entry to say it has no en-route dependency even though they also put it in Heathrow's part of the AIP.
