Scotland Yard has confirmed a PC and a Sergeant for missing 12-year-old Tia's body at a house in New Addington, near Croydon. The Constable was also taken off specialist search duties.
They were part of the team that failed to find Tia's remains despite searching her grandmother Christine Sharp's home three times.
Police said lessons have been learned following an investigation into the "errors".
A Scotland Yard spokesman said: "The internal review into the searches at The Lindens during the Tia Sharp enquiry has been completed.
"A number of organisational learning points were identified which will be taken forward with the aim of helping to reduce any similar errors occurring in the future.

"Two officers, a PC and a Sergeant have received words of advice. A PC has been removed from search duties."
Tia's body had been wrapped in a sheet and plastic bag and hidden in the loft of her 47-year-old grandmother's house.
When she was eventually found on August 10th her body was badly decomposed because of the hot weather.
Experts failed to establish a cause of death and detectives fear they may never know how she died.
Met Police Commissioner Bernard Hogan-Howe apologised to Tia's mother Natalie for not finding her daughter sooner.
At the time he claimed the blunder was not down to any one individual officer, adding: "We want to learn lessons from this particular case."
Christine's boyfriend Stuart Hazell has been charged with the youngster's murder.
The 37-year-old, of New Addington, is due at the Old Bailey for a plea and case management hearing later this year.
