Connecticut is the best-instrumented heating oil market in the country. The state runs its own weekly dealer survey and publishes a searchable credential register, so a household here can check both the price and the dealer without taking anyone's word for it.

State level print for the week ending 30 March 2026. The survey pauses after March, so this figure ages until the season resumes in October.
Where this sits
Of the twenty one states with a published print for this week, Connecticut ranks 15. The cheapest is Nebraska at $3.97 and the dearest is Delaware at $5.91, a spread of $1.94 a gallon. On a 261 gallon fill that national spread is worth $506.60.

The market here
Dense, competitive and dominated by independents, with the national retail brands layered over the top in the Fairfield County and Hartford corridors.
Fuel rules
Connecticut has legislated a rising biodiesel blend requirement for heating oil sold in the state. Ask a dealer what blend is in the truck, because the answer changes the energy content of the gallon you buy.
Ordering
Use the DEEP survey the week you order. It is a real distribution of dealer quotes, and a quote well above the range is worth one more phone call.

The state survey and the federal print
Connecticut points at the Connecticut DEEP weekly heating oil price survey. Where a state runs its own dealer survey it usually samples more dealers than the federal collection does in that state, so the two figures will not match exactly and neither is wrong. Use the state survey to sanity check a quote in the week you order, and the federal series to compare across states.
Assistance
Help here runs through Connecticut Energy Assistance Program. Applications go to the state, never to the federal office, and for a delivered fuel the benefit is normally paid to a participating dealer against a delivery rather than to the household.
