Why an energy credit check catches people off guard
You go to switch, fill in the online form, and halfway through there’s a line about a credit check you weren’t expecting. Cue a small wave of panic about mortgage applications, car finance, or whatever else is sitting on your credit file right now.
Take a breath. In the vast majority of cases, an energy credit check doesn’t touch your credit score at all. The confusion comes from the fact that “credit check” covers two very different things, and suppliers rarely explain which one they’re doing.
It’s a strange bit of the switching process to leave unexplained, given how much anxiety a single unclear line can cause. Suppliers have got better at flagging it upfront, but plenty still bury it in the small print rather than the headline steps.
Will switching energy supplier affect my credit score?
Usually not. Most suppliers run what’s called a soft search, which lets them see enough about your financial history to decide how to bill you, without leaving any mark that other lenders can see. Experian is explicit on this: soft searches aren’t visible to companies, so they have no impact on your credit score.
The exception is a hard search, which some suppliers use, particularly if you’re asking to pay by direct debit rather than upfront. A hard search is recorded on your report and stays there for around 12 months, where any company searching your file can see it. One on its own has only a small, temporary effect. It’s several close together, from any type of lender, that starts to add up, because the pattern of searches itself reads as risk.
What an energy credit check is actually looking for
Suppliers aren’t deciding whether to “approve” you the way a bank might. They’re deciding two practical things: how much deposit or upfront payment to ask for, if any, and whether to offer you a standard credit meter or push you toward a prepayment meter instead.
A thin credit file, a recent house move, or a history of missed payments elsewhere can all nudge that decision. None of it stops you switching. It just changes the terms you’re offered on day one.
How to find out which type of check you’ll get
Ask before you apply. Suppliers should tell you upfront whether they’re running a soft or hard search, and a reputable comparison journey will flag it during the switch rather than burying it in the terms. If in doubt, ask outright: “is this a soft or hard credit check?”
If a hard search genuinely worries you, mainly because you’re mid mortgage application, it’s worth asking your target supplier whether a soft search option is available before you commit. Many will offer one if you ask directly. Checking your own credit report first costs you nothing, since looking at your own file is a soft search and has no effect however often you do it.
What if I have little or no credit history?
A thin file trips up an energy credit check just as often as a poor one. Recent movers, people new to the UK, and younger switchers signing their first tariff in their own name can all get flagged simply because there isn’t much data to check, not because anything’s gone wrong.
If that’s you, the practical result is the same as a poor score: possibly a deposit, possibly a prepayment meter to start with. It’s worth mentioning upfront that you’re new to credit rather than letting the supplier guess, since some will offer a lighter check if you explain the gap. If you’ve recently moved and you’re renting, our switching while renting guide covers the extra steps that come with a new tenancy on top of the credit side.
A poor credit score doesn’t stop you switching supplier
Your home does not get left without energy because of your credit file. Suppliers work within Ofgem’s rules on supplying domestic customers, and a weak credit history changes how you pay rather than whether you are supplied at all. In practice that usually means a prepayment meter or a higher upfront deposit rather than a rejected application.
If you’re currently on a prepayment meter and want options beyond it, our prepayment meter rights guide covers what you’re entitled to ask for as your circumstances change.

Frequently asked questions about energy credit checks
- Can I refuse an energy credit check?
- You can decline, but most suppliers will then ask for a larger upfront deposit or offer a prepayment meter instead, since they’ve no other way to assess the risk.
- Does an energy credit check show up to mortgage lenders?
- Only a hard search would appear on your credit file where a mortgage lender could see it, and it stays visible for around 12 months. A soft search stays invisible to everyone except you.
- Will checking my own credit report before switching hurt my score?
- No. Checking your own report is a soft search and has no effect on your score or your chances of being accepted, no matter how many times you do it.
- Will switching twice in one year trigger extra checks?
- It might, since some suppliers view frequent switching as a minor risk factor, though it won’t stop you switching again.
- Do all energy suppliers run a credit check?
- Most do in some form, but the type and strictness varies, which is why asking directly before you apply is worth the thirty seconds.
- Does a joint account mean both people get checked?
- Usually only the named account holder is checked, though this can vary slightly by supplier.
An energy credit check sounds a lot scarier than it usually is. Ask which type you’re getting, and in most cases you can strike it off your list of things to actually worry about before you switch. Save the actual worry for whether you’re on a competitive rate in the first place.
