Constellation Energy customer service
Constellation Energy earns mostly positive reviews on Google and Trustpilot, with many customers praising its competitive rates and helpful customer service. However, the company does not offer a satisfaction guarantee in Texas, which limits your ability to cancel or switch plans without penalty. This downside negatively impacted Constellation’s overall customer service score, resulting in 3.1 out of 5 stars.
Constellation Energy online accessibility
Constellation Energy offers a convenient digital platform that lets customers manage their accounts and pay their bills. However, its accessibility score was lowered to 4.3 out of 5 due to plans with usage minimums that can result in confusing pricing structures.
Constellation Energy plan options
Constellation Energy receives 4 out of 5 stars for plan variety, thanks to a mix of plan types and green energy options. Despite this, it didn’t earn a perfect score because its offerings are limited to fixed rates and one- to two-year contracts.

Positive reviews
“When I called Constellation customer service to inquire if I would be able to get their new, lower rate since I had just signed up for their service less than a month before, the gentleman was very pleasant and helpful. They did give me the lowest rate and I was both pleased and grateful.” – MAB. (Trustpilot)
“Switching was a breeze, everything was explained thoroughly.” – Latrina T. (Trustpilot)

“Customer service (was) not helpful, same ‘canned’ message every time I speak to them.” – RR. (Trustpilot)
“I’ve had no communication or updates from (Constellation Energy) after signing up.

(Trustpilot)
