32 year old Joshua Miller is accused of murder, while 27-year-old Jamie Cooper is charged with preventing a lawful burial.
The pair, both from Wandsworth, are due in court today after being remanded in custody.
The investigation began after officers were called to Kingfisher Court.
Officers attended the scene but no-one was found in the property, however, after carrying out a search, officers believed someone had come to harm at the address and an investigation was launched.
On Friday, officers attended a wooded area in Borstal, Kent where a man was found deceased.
Although formal identification is yet to take place, officers believe they know the identity of the victim and have contacted his next-of-kin, who are being supported by specialist officers.
The victim and the two men charged were known to each other.
