Last of the Summer Wine's thirty first series was aired in 2010, beginning on 25 July. All six episodes in series thirty one were thirty minutes in length. All of the episodes were written by Roy Clarke and directed by Alan J. W. Bell.
This series is the first in 19 years to be 6 episodes long, this is due to the show originally due to be axed but the BBC re-commissioned the show , Juliette Kaplan who plays Pearl said on her website that this series is due to the fans response to the axe rumours in December 2008. Alan J.W. Bell has also credited this series due to fan response.
This series continues with the same trio as series 30 with Russ Abbot (Hobbo), Burt Kwouk (Entwistle) and Brian Murphy (Alvin), Peter Sallis (Clegg) and Frank Thornton (Truly), who were previous main characters, remained as secondary characters, they only filmed studio scenes due to the cost of insurance for the actors at their age on location, Jane Freeman (Ivy) also filmed in studio only scenes as well.
On the 2nd June 2010 the BBC announced that the 31st series would be the last series despite still having a strong fan base and series 30 averaging over 4 million viewers an episode. To commemorate the show the BBC broadcast Songs of Praise from Holmfirth, and show a special Countryfile about Last of the Summer Wine and Holmfirth and the surrounding area . The Countryfile special aired on 25th July straight after the first episode of the final series.  Songs of Praise from Holmfirth aired on 29th August on the day the last ever episode was broadcast.
That final episode, "How Not to Cry at Weddings" was dubbed "The Very Last of the Summer Wine" in the Radio Times edition dated 28 Aug - 3 Sept 2010. That title modification was not used when the episode was transmitted, however. The specified Radio Times edition included a lengthy article on Peter Sallis titled "It never occurred to me that I could be an actor".
This being the last series, inherently all twenty remaining cast characters made their final appearances. Ivy and Nelly's final appearances were in the penultimate episode, "Look Whose Wheel's Come Off". The remaining eighteen, listed below, signed off in the final episode, "How Not to Cry at Weddings". Most notable, of course, must be Norman Clegg who appeared in every one of the 295 episodes.
