Sir Bob (pictured above at February's Amnesty International Concert), 62, arrived with daughter Pixie, 23, at Heathrow before making his way to his Battersea home in south west London.
Just a day after releasing a statement describing the family as being "beyond pain", the Live Aid founder arrived from San Francisco for today's postmortem on what police have called a "non-suspicious but unexplained and sudden" death.
The police were called to 25-year-old Peaches' Kent house by worried neighbours on Monday, where they found the mother-of-two dead.
Yesterday's search on the five bedroom property conducted by forensic officers and sniffer dogs found no trace of drugs, a suicide note or sign of injury.
Peaches had widely been seen as finally having found her calling in motherhood, writing in her Mother and Baby column last month:
"I lived a life of wanton wanderlust. Other than work there was nothing stopping me from having constant fun. But it was becoming boring, I wanted an anchor – I craved it."
Then came her ‘two fat little cherubs’ Astala and Phaedra- still just babies- by 23-year-old rocker husband, Thomas Cohen.
She wrote: "I had the perfect life, two beautiful babies who loved me more than anything. It was, and is, bliss. The transition can be hard and scary. I had it all. I’m happier than ever.
"My real old friends have stuck by me and connect me to my old life…right now life is good."
