• Parent Company: Centrica plc
• Years in Texas: 15

• Avoid If: You want a good app and online tools—theirs are bare-bones
• Deposit Required: Conditional (credit score 650+ typically means no deposit)

Company Overview

Frontier Utilities saves you $200-$350 per year compared to TXU and Reliant [ComparePower rate analysis]. Same electrons. Same grid. Different price tag.

Centrica plc [LSE: CNA]—a British energy giant worth more than Vistra (TXU’s parent)—owns Frontier. They’ve operated in Texas since 2008. No bankruptcy scares, no financial instability. They just don’t advertise.

That’s the entire pitch: Frontier skips the Cowboys sponsorships, the Texans stadium naming rights, the rewards programs you’ll never use. Those savings land in your pocket—10-15% below the big brands on almost every plan comparison we’ve run.

The trade-off exists. Frontier’s app looks like it was built in 2012. Hold times hit 20-30 minutes. Nobody will proactively call you about anything. But if you set up autopay and don’t need hand-holding, Frontier is the obvious choice for price-conscious Texans.

Where Frontier Operates

Frontier serves deregulated areas across Texas including Houston, Dallas–Fort Worth, parts of the San Antonio area, Corpus Christi, and regions covered by Oncor, CenterPoint, AEP Texas, and TNMP.

Plan Types Offered

Fixed-Rate Plans Standard lock-in rates from 1-36 months. Often priced competitively against larger competitors.

Variable-Rate Plans Month-to-month with no commitment. Rates fluctuate with the market.

Green Energy 100% renewable options available for environmentally-conscious customers.

Deposit Requirements

Frontier runs credit checks. Score above 650? No deposit. Below that? You’re paying $50-$150 upfront depending on how far below.

Frontier doesn’t offer prepaid plans. If your credit is rough, look at Payless Power or Discount Power’s prepaid options instead.

Budget First, Everything Else Second

Frontier’s pitch: why pay for Reliant’s app and TXU’s call center if you never use them?

What you won’t find at Frontier:

• Rewards points
• Free nights or weekends promos
• Home security bundles
• An app worth downloading

What you will find: rates that are often 10-15% lower than the big brands. That’s real money—$15-$25/month on a typical Texas home.

Customer Service: The Real Story

Frontier cut costs by cutting customer service infrastructure. You’ll notice.

Worth knowing:

• Phone wait times: 20-30 minutes average [Service testing, Q4 2025]—it’s consistent.
• Website: Pays your bill. Shows your usage. That’s it. No fancy dashboards.
• Daily usage texts: Actually useful for tracking spending.

The catch:

• Complex billing issues take multiple calls to resolve
• No 24/7 support—call during business hours or wait
• Online reviews consistently cite poor service as the trade-off for low rates

The math: Frontier saves you $200-$350/year. TXU’s better customer service costs $200-$350/year. Neither is wrong—just know what you’re choosing. If you call customer service once a year, Frontier wins. If you need regular help, pay the TXU premium.
