Payment channels

Pay Aquarion Water Company of New Hampshire

Use the provider’s verified online, telephone, mail, or counter instructions. Check the final confirmation screen for the amount, processing date, and any transaction fee before submitting.

Primary online route

Use the official payment portal

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as KUBRA for one-time payments; Aquarion Customer Portal for enrolled accounts.. Never enter account credentials into a lookalike site reached through an unsolicited message.

2026 transaction pricing

Convenience fees

New Hampshire residential customers are not identified as subject to the $1.95 KUBRA fee in the payment page’s stated list; the page specifically applies that fee to Massachusetts and non-residential Connecticut/New Hampshire customers. Confirm the live transaction screen for the current 2026 amount.

Fees can vary by payment type, channel, account class, and processor terms. The checkout screen is the final fee disclosure.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by Aquarion Water Company of New Hampshire and matched to the account information on your bill. Online portals are convenient, but telephone, mail, counter, and drop-box options may follow different posting schedules and may use different fees.

For a routine payment, save the final confirmation page or IVR number and check when the transaction will post. For a same-day shut-off notice, do not assume that submitting a card payment automatically stops a field order; ask the provider what amount and confirmation are required.

Never send your account number, password, card details, or bank information to Water Ledger. Those details belong only on the provider’s verified payment channel or at an authorized counter.
