Under the Lake - Final ratings

The third episode of the year's series of Doctor Who, Under the Lake, was watched by 5.63 million UK viewers within one week of its transmission (not including online views via BBC iPlayer).  This means the episode has become the lowest rated episode since Doctor Who's relaunch in 2005.   However, the episode charted slightly better than the previous week's episode, coming in a respectable 22nd place.

Both The Witch's Familiar and Under the Lake were affected by being scheduled against important England Rugby World Cup on ITV.  With England now knocked out of the competition, Doctor Who ratings are likely increase.  The last episode, Before the Flood, had an overnight rating of 4.38 million so is likely to reach over 6 million after seven days.
