How do I make a Child Benefit claim in London and does living in London affect what I can receive?

You claim Child Benefit through the same UK-wide process whether you live in London or elsewhere, usually online through GOV.UK or by completing form CH2. You may claim for a child under 16, or under 20 if they remain in approved education or training, and only one person can claim for each child. The amount is set nationally, but the High Income Child Benefit Charge may reduce the tax advantage for people with higher adjusted net income. Check the latest rules and claim online at GOV.UK, or contact HMRC if your circumstances are unusual.
