Yes, not only those but also charts from
- Jeppesen
- French SIA (they cover the southern UK coast)
- French IGN (as above)
- French Cartabossy (as above)
etc
Equally legal will be other electronic representations which never existed in paper form e.g. Jeppesen Flitestar charts, PocketFMS chart data, etc. These are likely to be more current than printed charts anyway.
The thing which would IMHO be foolish would be flying with a printed chart which is say 5 years old. Yet, the latest VFR chart for Greece is the 1998 ONC one
