Tell us if anyone moves in or out of your household
You must tell us as soon as possible if someone in your household reaches their 18th birthday, or someone aged 18 or over moves in or out, as this may affect your bill.
If the change means that there is only one person aged 18 or over in the household, you can claim a single person discount.
If someone turning 18 is a full-time student, you can apply for a student discount.
If someone turning 18 is not a full-time student but child benefit is still being claimed for them, you can apply for a school leavers discount.

If you are claiming council tax support (CTS), you may also need to notify the Benefit Service of your change in circumstances.
