Overview

Does it even matter?

Same wires. Same grid. Same electrons. Neither company sponsors the Cowboys or runs rewards programs. Both skip the brand premium. But they’re solving different problems.

Here’s what separates them: Frontier exists for customers who need prepaid. Credit issues? No deposit? Just need power today? Frontier’s been doing that since 2008.

Rhythm exists for customers who are tired of confusing bills. The rate they show includes everything. No hidden fees, no tier games, no decoder ring required.

The real question: Do you need prepaid flexibility or pricing transparency? Frontier has the first. Rhythm has the second. Both are cheaper than TXU or Reliant.

Company Backgrounds

Frontier Utilities is backed by Centrica plc—a massive British company that owns British Gas. International corporate backing with 15 years in Texas. They’re not going anywhere.

Rhythm Energy is venture-backed and independent. Founded by people who came from major energy companies, not startup founders playing in a new space. Only 5 years old, but they’ve built real credibility through transparent practices.

Frontier has the track record. Rhythm has the momentum.

Plan Variety

Frontier keeps it traditional:

  • Fixed-rate (1-36 months)
  • Variable rates
  • Prepaid (no credit check, no deposit)
  • Green energy options

Rhythm goes deeper on features:

  • Fixed-rate plans with transparent pricing
  • Variable rates
  • Indexed plans (tied to wholesale prices)
  • Solar buyback (excellent rates)
  • 100% renewable options

Frontier has prepaid. Rhythm has indexed plans and solar buyback. Neither has free nights or weekend specials.

Deposit Policies

Frontier: Credit check for standard plans. If you don’t qualify, prepaid skips the deposit entirely—no credit check, no upfront cost.

Rhythm: Credit check required. AutoPay enrollment can help qualify some customers. No prepaid alternative.

If credit is your issue, Frontier wins by default. Rhythm doesn’t have a no-credit-check option.

Customer Experience

This is where they really diverge.

Frontier: Budget service for budget prices. Phone support with 20-30 minute waits. Website that works but looks like 2010. Prepaid customers get daily usage texts—helpful. No app worth mentioning.

Rhythm: Built for people who manage everything on their phone. Their app is genuinely excellent—real-time usage tracking, clear billing, no surprises. Support is digital-first (chat, email) with good response times. No phone support in the traditional sense.

If you’re comfortable managing things digitally and want to see what you’re using in real-time, Rhythm is miles ahead. If you want to call someone when something goes wrong, Frontier has a phone number (with long waits).

The Verdict

Frontier for budget and flexibility. Rhythm for transparency and tools.

Choose Frontier if:

  • Price is your #1 factor and you want the cheapest rate
  • You need prepaid electricity (credit issues, no deposit)
  • You prefer a company with a 15-year Texas track record
  • You don’t use apps and just want basic service
  • Corporate backing from a British giant helps you sleep at night

Choose Rhythm if:

  • You have solar panels and want competitive buyback rates
  • Transparent pricing matters—you want to know exactly what you’re paying
  • You manage your life through apps and want real-time usage data
  • You’re comfortable with a digital-first, newer company
  • Indexed plans interest you (willing to take on price variability)

The honest take: Frontier is for people who want the cheapest possible electricity and will never think about their power company again. Rhythm is for people who want to understand what they’re paying and prefer modern tools. Both are good at what they do—they’re just serving different customers.

If you have solar panels, Rhythm’s buyback rates make them worth serious consideration even if you’d normally lean budget.
