World Jewish Relief, Children in Need and Homeless Action in Barnet were among beneficiaries of Finchley Reform's activities. Organiser Debbie Juggler said: "We also continued our work on the Glebelands nature reserve, baked biscuits for the FRS friendship club, held a bake sale and promoted the FRS green group."

One of the participating schools was Hertsmere Primary, where pupils laid coins on a giant photo of Pudsey Bear - it was Children in Need day - to raise money for charity. Akiva pupils in Finchley baked challah for patients at the North London Hospice, decorated plant pots for care home residents and invited elderly guests to tea and entertainment. Children from Kenton's Sobell Sinai Primary visited the Barnet General Hospital children's ward to present gifts of picture frames that had been made at school.
