How CMS Payment Bands Work
Nil Rate: £0 if income is very low or certain benefits apply.
Flat Rate: Around £7 per week if on benefits.
Reduced Rate: Lower payments for income roughly £100–£200/week.

Can Expenses Reduce Payments?
Most everyday costs do NOT reduce CMS payments:
- School fees
- Travel
- Clothing & essentials
- Holidays or activities
- Extra voluntary payments
However:
- You can request a Mandatory Reconsideration (MR)
- If refused → appeal to a tribunal
- Some costs (like travel for contact) may be considered in rare cases
Each case depends on evidence and circumstances.
