Child Benefit rules are the same in Manchester as elsewhere in the UK. You may qualify if you are responsible for a child under 16, or under 20 if they remain in approved education or training, and you meet the relevant residence and care conditions. Your income does not usually prevent a claim, but an income-related tax charge may apply when your adjusted net income is above the applicable threshold. Check the latest rules and apply through the official GOV.UK Child Benefit page, including if you want National Insurance credits.
