61 year old Paul Sander was sentenced at Guildford Crown Court after pleading guilty to 10 offences.
The offences included direct sexual contact, assault, voyeurism, public indecency and taking indecent photos of children.
Surrey Police have said that he will not be eligible to apply for release for ten years and then only if the parole board considers it safe.
Detective Sergeant Alastair Bagshaw, said: “Paul Sander is a dangerous sexual predator and I am pleased that this was recognised in the lengthy, and type of, sentence that he has received.
“Because of this, he will not be eligible to apply for release for ten years and even then, only if the Parole Board consider him safe to do so.
“I cannot emphasise enough how much admiration I have for the strength that Sander’s victims have shown in coming forward and talking about the horrific experiences that they had to endure. It is thanks to their bravery that he is now no longer a risk to other children.
“I hope that this case can reassure others that Surrey Police is committed to protecting and supporting vulnerable people and bringing dangerous offenders to justice.”
