Surrey Police said they were not looking for anyone else in connection with their investigation.
The boys’ mother Angelika Swiderski paid tribute to her sons as “happy, active children, full of life and happiness”.
“They were always smiling and even when I looked sad, they would say ‘Mummy smile like us’,” she added.
Senior investigating officer DCI Kimball Edey said: “I would like to express my sincere condolences to the family of Dominik, Kacper and Nikodem for their loss.
“They will continue to be supported by specialist officers as our investigation continues. I would ask that their privacy is respected at what is a tremendously difficult time for them.”
