How do we check every number we publish?

Every number here makes three promises. If a number can’t keep all three, it doesn’t go on the page.

Official sources come first. Here’s who they are and what we use each one for.

Each guide lists its own sources at the bottom, with links. Tap “Show all sources” on any page to see them.

Pick what you’re checking and where you live. We’ll show you the official place to look. It’s the same place we look.

Links go to official sites, plus two nonprofits we name as nonprofits. We don’t earn anything from them.

Sometimes two official sources say different things. When that happens, the more binding source wins, and we show you both sides.

Real examples

• Illinois, checked August 2026: Ameren Illinois’s battery rebate page left out a virtual power plant rule that Ameren’s own bulletin required. Our guides follow the bulletin and tell you to confirm in writing.
• Texas: if a plan’s ad shows one price and its Electricity Facts Label shows another, we use the label. It’s the official sheet Texas requires for every home plan.
• Anywhere: if a company’s website and its contract don’t match, we go with the contract. Then we tell you to get the promise in writing.

Every number goes through the same 5 steps. We don’t skip a step to be first.

1. 1
   Find it

   We start at the official source, not someone’s summary of it.

2. 2
   Trace it

   We name who published it and when.

3. 3
   Cross-check it

   If a second official source covers it, we check that one too.

4. 4
   Label it

   If it’s our own math, we mark it as an estimate and show the inputs.

5. 5
   Log it

   It goes in the page’s source list. Any later change goes in the changelog.

Some things never go on this site, no matter who asks or how many clicks they’d bring.

The full list

• A number we can’t trace to an official source and a date.
• A rate or program rule before it’s officially published.
• A savings promise. Savings only show up as labeled estimates, with the math.
• An expired deal described as if you can still get it, like the federal homeowner solar credit after 2025.
• A score or rank for a company that pays us, or a paid spot inside any ranking.
• Fake deadlines, countdown timers or “only a few left” claims.
• Reviews written to look like they came from real customers.
• Any hint that we’re part of a utility, a government agency or a state program.

Prices and rules change. Each page shows two kinds of dates, and certain events make us check again right away.

What makes us check again

Every guide uses the same labels. Here’s what each one tells you.

Every page uses these same labels. If one isn’t clear, tell us and  we’ll make it clearer.

Not partners, not advertisers and not the companies we review. Here’s how we keep it that way.

• Partners never review, edit or approve our guides or scores.
• We don’t rate companies we partner with.
• Partner offer sections are labeled, and they use each partner’s own approved descriptions.
• Advertisers don’t pick our topics or see a page before it goes live. Google picks the ads, and ads never run on trust pages like this one.
• Companies we review don’t get a preview. If a company sends us a public record we missed, we check it like anyone else’s.

We write for regular people, not experts. Here’s what that means on every page.

• A team, not a byline. The Day Company review team writes and checks every guide. We publish as a team.
• The answer first. You get the short answer in the first few lines, then the details.
• Plain words. Short words and short sentences. When a key term matters, like “net metering” or “early cancellation fee,” we keep it and explain it.
• Honest about “it depends.” When the answer depends on your home or your plan, we say what it depends on.
• Fair to every company. One public formula, used the same way for everyone. See how we score.

Tell us. We’d rather fix it today than leave it up.
