Adoption in England and Wales is open to anyone over the age of 21 regardless of their relationship status. Single applicants as well as same-sex and heterosexual couples can all apply. However, you must have a permanent address in England or Wales (even if you are not a British citizen) and you must not have any criminal convictions (although this only applies to certain offences). For those who are looking to adopt through a local authority or an agency, there will be an assessment process.
