•
Francesca Annis as Joyce Cameron. Joyce is a pillar of the community, and the historical leader of the Great Paxford Women's Institute. Joyce is sophisticated and serene, and even her ex-nemesis Frances observes that she is a natural leader. Even though she can appear stern, pompous and vindictive, she is actually quite sympathetic to other people and proves herself to be a substantially good person. • Daisy Badger as Claire Wilson (née Hillman). The former maid of Joyce Cameron and current maid of Frances Barden. • Mark Bazeley as Bob Simms. An aspiring author following the minor success of his first book. He was a journalist in the First World War and suffered injuries to his arm and leg from shrapnel, though he admits it was nowhere near combat. Volatile, self-centred and pathetic, Bob is physically and emotionally abusive to his wife Pat. •
Leanne Best as Teresa Fenchurch. Great Paxford's new local teacher. She becomes a tenant in Alison Scotlock's home. •
Samantha Bond as Frances Barden. Leader of the WI. •
Clare Calbraith as Steph Farrow. A farming wife who comes to enthusiastically support the WI after some initial reluctance to join. Steph is very happy with her husband and only wants what is best for him; when he decides to enlist, she supports him through love rather than reason. •
Chris Coghill as Stanley Farrow. The local farmer and Steph's husband. He is brave and wants to enlist in the war, despite having unpleasant memories of the last conflict in which he served. Stanley loves his wife and son (also named Stanley) and works hard to provide for them. •

Claire Price as Miriam Brindsley. The wife of local butcher Bryn, and a member of the WI. The thought of war terrifies her, as she knows it will eventually take away her son David. •
Claire Rushbrook as Pat Simms. A member of the WI. A battered wife, she has been a victim of her husband Bob's physical and verbal abuse for many years. She makes every effort to keep him happy, but remains with him out of fear. She lies about his abuse and makes apologies for his behaviour. •
Daniel Ryan as Bryn Brindsley. The local butcher and husband to Miriam. Bryn fought in the First World War and survived. However, he was scarred by the events and Miriam forbids him from enlisting again. He cares greatly for his family and offers advice to his son David, who is determined to enlist. •
Fenella Woolgar as Alison Scotlock. Alison is a member of the WI. She lost her husband George during WWI, and his name can be seen on the memorial wall. Frances tells her husband that the WI is essential in Alison's case, because if she was not a member she would never leave the house and her life would revolve around looking at the memorial wall and caring for her dog, Boris. •
Jodie Hamblet as Jenny Marshall. Jenny is the switchboard operator for Great Paxford and works alongside Pat. • Jacqueline Pilton as Cookie. An elderly member of the WI.
