Child Benefit is claimed through HMRC, not Manchester City Council, and the rates are set nationally, so they do not normally vary by location. You can usually claim if you are responsible for a child under 16, or under 20 if they remain in approved education or training. Apply online through GOV.UK or use form CH2, and make sure you claim promptly because delays can affect National Insurance credits. If you or your partner has a higher income, the High Income Child Benefit Charge may apply, depending on your circumstances.
