Notice and timing
How delinquency is handled
Grace period after the due date
SPU considers a bill past due if it is not paid by the due date printed on the bill. The public customer pages do not state one universal numeric grace period before the first late charge; further collection action can include late fees, past-due notices, and service interruption. Customers receiving an Urgent Notice or Final Shutoff Notice should act immediately because the Final Shutoff Notice is described as the last notification.
Late-fee calculation
Seattle's public customer pages describe late fees and collection action but do not publish a single current percentage in the ordinary payment guide. The final bill and applicable Customer Account and Billing Management rules control any charge. Customers can avoid escalation by paying the balance, arranging a short-term plan within 60 days, enrolling in PromisePay when eligible, or applying for emergency assistance; SPU says payment plans are available to all customers regardless of income or immigration status.
Disconnection timeline
If a bill is not paid by its due date, SPU treats it as past due and may issue past-due notices. The customer-facing sequence culminates in an Urgent Notice and then a Final Shutoff Notice; the Final Shutoff Notice is the last communication before disconnection. The public page does not provide one universal day-count because account history and collection status affect scheduling. To prevent shutoff, pay the past-due balance, set up a payment plan, or apply for assistance. If already disconnected, call 206-684-5800 to pay, arrange a plan, and schedule reconnection; same-day restoration is not guaranteed.
