Nikko Oil, LLC describes itself on its website as a family owned and operated home heating oil delivery business from Canterbury, CT. The site says it accepts Access and TVCCA. Its stated service area includes Norwich, Plainfield, Putnam, Killingly, Griswold and Montville. An r/Connecticut commenter says pretty much 97% of their deliveries are from Nikko Oil. A 2026 r/Connecticut commenter said the company had been easy to work with and "100% accurate on their delivery day/time, even immediately after storms." A 2025 customer said the company came out on a Sunday morning of Christmas weekend, at 9am. A 2025 customer who was not a regular and was low on oil said Nikko came the next day and topped off the tank. A 2024 customer who used Nikko through the heating assistance program said the company filled the tank, and that the man who delivered the oil also restarted the furnace. A 2023 customer said Katelyn or Christy always answered calls in a cheerful manner and took the time to answer questions during busy times of the year. A 2024 customer said a delivery mistake, once confirmed as the driver's error, was quickly fixed. A 2023 customer said that when the company calls to confirm an order and the call is missed, it cancels the order, and advised answering. A 2023 customer gave one star after leaving a coupon in the door that the driver did not take.
