Notice and timing
How delinquency is handled
Grace period after the due date
Five additional days after the payment due date are allowed for a payment to post before MDC applies interest to the remaining unpaid balance.
Late-fee calculation
After the five-day posting allowance, MDC applies 1% interest to any remaining unpaid balance. The account may also enter the formal collection process, with repeated notices, shutoff, a property lien, and potential legal referral if the delinquency continues. The reviewed 2026 pages do not identify a separate fixed late fee beyond the 1% interest.
Disconnection timeline
MDC does not publish one fixed day-count from the first missed due date to field shutoff. The published process is several attempts to contact the customer, a serious-past-due/final notice, and possible shutoff if payment or a payment plan is not made after the final notice. Customers should call 860-278-7850 press 4 immediately after receiving the notice.
