Suggestions to find Gracenote IDs for UK channels?

[sheilnaik]

I’ve seen comments about folks using Zap2It to find the Gracenote IDs for US channels (for use with the tvc-guide-stationid tag in custom m3u playlists). Is there an equivalent to find Gracenote IDs for UK channels?

I know of one round about way

Find lineups in UK postal code L2 2DP
http://192.168.1.4:8089/tms/lineups/gbr/L2%202DP
"lineupId": "GBR-1000118-DEFAULT","name": "United Kingdom - National",
"lineupId": "GBR-1000193-DEFAULT","name": "United Kingdom (extended) - National",
"lineupId": "GBR-1000040-DEFAULT","name": "Freeview",
"lineupId": "GBR-OTABL2",         "name": "Local Over the Air Broadcast",
"lineupId": "GBR-1008138-DEFAULT","name": "Astra FTA - National",
"lineupId": "GBR-1000039-DEFAULT","name": "Freesat - North West",
"lineupId": "GBR-1002100-DEFAULT","name": "Freesat from Sky - National",
"lineupId": "GBR-1000042-DEFAULT","name": "Sky SD - North West",

one of them is Freeview using "lineupId": "GBR-1000040-DEFAULT"
{
 "type": "OTA",
 "device": "DEFAULT",
 "lineupId": "GBR-1000040-DEFAULT",
 "name": "Freeview",
 "location": "North West",
 "mso": {"id": "1000004","name": "DTV Services Ltd"}
}

So Freeview uses GBR-1000040-DEFAULT
Find stations in lineup GBR-1000040-DEFAULT
http://192.168.1.4:8089/dvr/guide/stations/GBR-1000040-DEFAULT
one of the results is BBC1NWHD using "stationId": "120572"
{
  "type": "",
  "name": "",
  "channel": "101",
  "callSign": "BBC1NWHD",
  "stationId": "120572",
  "preferredImage": {
    "uri": "https://tmsimg.fancybits.co/assets/s120572_ll_h15_aa.png?w=360&h=270",
    "height": "270",
    "width": "360",
    "primary": "true",
    "category": "Logo",
    "text": "",
    "tier": ""
  },
  "videoQuality": {"signalType": "Digital","videoType": "HDTV","truResolution": ""}
}

And using the call sign in the station id lookup agrees
