The church in Kent, southeast England, is also where the 25-year-old television presenter and socialite married musician Tom Cohen, the father of her two young children, in 2012.
It was also the venue for the marriage of Bob Geldof - who organised the Live Aid concert to raise money for the victims of the Ethiopian famine in 1985 - and Yates in 1986.
The Geldof family said the service on Easter Monday would be a private affair.
Police have described her death as "non-suspicious" but "unexplained". A post-mortem failed to establish a cause of death and toxicology tests are being carried out.
Peaches' mother died from a heroin overdose in 2000, aged 41.
