All licensed a/d's appear in the UK AIP.
If you look at
http://www.ais.org.uk/aes/pubs/aip/p...es/302BK01.PDF for example (Sywell) you will see in "Aerodrome Regulations" that only r/w 03/21 is licensed for night use.
If you look at
http://www.ais.org.uk/aes/pubs/aip/p...es/302KA01.PDF (Shoreham) under "Use of Runways" you will see that 02/20 (grass) is unlicensed.
Also on the ICAO aerodrome chart 02/20 (grass) is clearly marked as unlicensed.
