It is quite difficult at this stage of their lives, to distinguish between this species, the Herring Gull and indeed others among this particular group of birds unless well versed in their differences. However, I am inclined to think that this is a Lesser Black-backed Gull particularly because of its totally black bill. One of the least confusing of determining characteristics.
