Vincent Tabak is due to face Bristol Magistrates' Court today accused of killing the 25-year-old.
Detective Chief Inspector Phil Jones, who led the inquiry, said that on Saturday evening Vincent Tabak was charged with the murder of Joanna Yeates.
He added: "I would like to pay tribute to Jo's family and Greg for their assistance and dignity in the most difficult of circumstances.
"Their support to us has been invaluable.
"I would also like to thank the general public for their help and the information they continue to provide to the investigation, and the residents of Canynge Road for their co-operation and patience."
Dutch engineer Tabak, who lived next door to Miss Yeates at 44 Canynge Road, Clifton, Bristol, was arrested on Thursday.
Specialist search teams have been examining Tabak's flat, which he shares with his girlfriend, Tanja Morson, an analyst for Dyson, in Malmesbury, Wiltshire.
Miss Yeates shared her rented home with her boyfriend, Greg Reardon, 27.
Tabak, a trilingual engineer, is an expert in the flow of people through buildings, including sports venues.
Tabak's arrest was the second to be made by detectives since Miss Yeates's frozen body was found dumped in a lane on the outskirts of Bristol on Christmas Day.
