September 2017

Dear Valued Reliable Oil Customer,

After servicing homeowners in Colchester and the surrounding area for the past 30 plus years, the ownership and management of Reliable Oil has passed ownership of the company effective August 1, 2017 to Daniels Energy. In an effort to ensure that customers would receive the same care and level of service,  Daniels Energy was chosen for its 91 years of continuous family ownership, its active participation in the Colchester community as members of The Colchester Business Association, and the availability of services that it will be able to provide to meet the growing home comfort needs of its customers. On behalf of the previous owners of Reliable Oil we extend their deepest gratitude for the loyal patronage you have afforded them over the years and they do so in knowing that you will be well taken care of by the Daniels Family and our Staff
