The service, which is open to the public, will take place on 8 September at the church, which remains central to the journalism community despite national newspapers moving away from the area.
Hammerl, a South African national who lived in Surbiton with his wife and three children, was shot and killed by pro-Gaddafi forces while covering the conflict within Libya.
For weeks it was believed that he was being held hostage along with four other journalists.
But upon their release it was revealed he had been fatally wounded at the time of the attack on the group.
According to a friend of the family, Hammerl's remains have not yet been located and returned.
At the end of May the president of South Africa Jacob Zuma claimed the Libyan authorities had indicated they would assist in finding Hammerl's remains.
The service will take place from 3-4pm on 8 September.
