You asked (1) if the law allows a home heating oil company to require a consumer to buy a minimum amount per delivery and (2) if it could do so without stating the requirement in it advertisement or through another means of communication.

The law prohibits retail fuel oil dealers from requiring regular customers to accept a minimum delivery of more than 150 gallons or 75% of the primary tank size, whichever is less (CGS § 16a-22a). The prohibition apparently does not apply to those who are not regular customers.

The law does not require dealers to state minimum delivery requirements in their advertisements. It requires dealers to give consumers, on delivery, a delivery ticket stating the per gallon price, the total number of gallons sold, and the amount of any delivery surcharge in a conspicuous place (CGS § 16a-21). It prohibits dealers from charging more than this amount. Violators are subject to a fine of up to $100 for a first offense and up to $500 for subsequent offenses.
