The authority is asking every resident to consider becoming a foster carer and has launched its very first fostering hub.
Sibling groups, young people aged 11 to 17 and children with disabilities are most in need of a home.
The hub connects foster parents with others in the borough, so they always have support and friendship.
They will also have access to a dedicated social worker, 24/7 support and a range of training and development opportunities.
If you are interested, you can register your interest by phoning 020 8770 5563 or by emailing fostering.duty@sutton.gov.uk.
