Did you know that today's heating oil burns cleaner than natural gas? It's called Bioheat—a blend of ultra-low sulfur heating oil with biodiesel, a domestic, sustainable heating oil replacement. And, it's the fuel that has been heating your home for years. We are proud to deliver Bioheat to the Gault family of customers.

Payment Options

Our payment programs suit every need and budget.

The Gault Advantage: This program is designed to protect you from winter bill spikes by way of one low monthly payment. To determine your monthly payment, we average your heating costs over the last two years and divide it into 12 equal payments. During the heating season, we will periodically review your account and make necessary adjustments to the payment amount.

Auto-Pay: Automatic payment options are designed to save you valuable time. We can automatically charge payments directly to a credit or debit card, or, for Gault Advantage customers, payment can be drafted from your bank account.
