Switch to a Standard Variable Tariff in the UK: is it worth it?

A standard variable tariff (SVT) can be a sensible short-term option for some households — but it isn’t always the cheapest. Compare whole-of-market deals with EnergyPlus and see if a fixed tariff could cut your bills without losing peace of mind.

  • Check if your current tariff is an SVT, fixed, or price-capped default
  • See whole-of-market options (not just one supplier’s deals)
  • Understand exit fees, risk, and when an SVT may suit you

Find out if an SVT is right for you — or if you can do better

Many UK households end up on a standard variable tariff after a fixed deal ends, or when they move home and don’t choose a tariff straight away. SVTs are often the easiest option because they’re flexible — but that flexibility can come with a higher price.

Use this page to weigh up whether switching to an SVT is worth it for your home, and then compare whole-of-market tariffs with EnergyPlus to see what’s available right now.

Quick tip: If you’re currently on a fixed deal, check whether you have an exit fee before switching. If you’re already on an SVT, you can usually switch without fees — but always confirm in your account or bill.

Important: The UK energy market changes. Whether an SVT is “worth it” depends on today’s prices, your meter type, payment method, and how long you plan to stay on that tariff.

When switching to a standard variable tariff can be worth it

A standard variable tariff (SVT) is a rolling tariff where the supplier can change prices (usually with notice). In the UK, SVTs are often linked to the Ofgem price cap (for most households on default tariffs), which limits the unit rates and standing charges suppliers can set for a typical customer profile.

You want flexibility

If you’re likely to move home soon or you’re waiting for better fixed deals, an SVT can be a useful “holding” tariff because you can usually leave without exit fees.

You’re coming to the end of a fixed deal

If your fixed tariff ends and you don’t switch, you may move onto your supplier’s SVT automatically. Sometimes it’s OK briefly — but it’s still worth comparing.

You’re unsure how long you’ll stay with one supplier

SVTs typically have no fixed term. If you don’t want to commit to 12–24 months, an SVT avoids long contracts (but often costs more).

You’re actively monitoring the market

If you’ll keep an eye on rates and switch quickly when a better tariff appears, an SVT can be practical in the short term.

You want protection from unusually high pricing

For most default domestic tariffs, the Ofgem price cap limits the maximum charges suppliers can set (though your bill still depends on your usage).

Reality check: “Worth it” often means “worth it for now”. If you stay on an SVT longer than needed, you may miss a cheaper fixed deal.

What is a standard variable tariff (SVT) in the UK?

A standard variable tariff is a supplier’s default energy tariff. The price can change over time, and you’re not locked into a set end date like you are with a fixed tariff. Many people end up on an SVT when:

  • a fixed tariff ends
  • you move into a new property and inherit the current supplier
  • you sign up and choose not to take a fixed deal

How SVT pricing works (unit rates and standing charge)

Your bill typically includes a unit rate (pence per kWh) and a standing charge (pence per day). On an SVT, these can move up or down when suppliers update prices, often influenced by the price cap level (where applicable) and wholesale costs.

Feature Standard Variable Tariff (SVT) Fixed Tariff
Price changes Can change over time (usually with notice) Usually fixed for the contract length
Exit fees Often none Often apply if you leave early
Best for Short-term flexibility, people likely to switch soon Budget certainty and longer-term planning
Common risk Paying more than necessary if you don’t review Being locked in if market prices fall

If you’re not sure what you’re currently on, check your latest bill or online account. Look for wording like standard variable, “default tariff”, or the name of a fixed plan with an end date.

SVT vs fixed tariff: what’s better for most UK homes?

For many households, a competitive fixed tariff can beat an SVT — especially if you value predictable bills. However, the “best” choice depends on your goals and how confident you are that you’ll switch again if prices move.

Reasons people choose an SVT

  • No long commitment — typically no fixed end date
  • Often no exit fees — easier to switch again
  • Simple — common default when a deal ends
  • Good as a short-term bridge while you compare deals

Reasons people choose a fixed tariff

  • Price certainty for the contract term
  • Easier budgeting month to month
  • Potential savings vs SVT if the market is competitive
  • Peace of mind if prices rise during your term

A practical rule of thumb

Choose SVT if you need flexibility and you’ll review again soon.

Choose fixed if you want predictable rates and can accept possible exit fees.

Compare first if you’re unsure — the cheapest option depends on your postcode, meter, and payment method.

Not all SVTs are identical: rates and standing charges can vary by region and supplier. Comparing whole-of-market gives you a clearer view of what’s realistic for your home.

How to switch tariffs (and what happens to your supply)

Switching your home energy tariff in the UK is usually straightforward. Your gas and electricity supply stays on — you’re simply changing who bills you and at what rates.

  1. Check your current tariff. Look for the tariff name, end date, and any exit fee.
  2. Compare whole-of-market options. Consider unit rates, standing charges, contract length, and payment method.
  3. Apply to switch. Your new supplier (or switching journey) handles the admin.
  4. Submit meter readings if requested. This helps ensure accurate final and opening bills.
  5. Keep an eye on confirmations. Save emails/letters showing your tariff details and start date.

Will my energy go off?

No — switching supplier doesn’t interrupt your supply. Your electricity and gas still come through the same networks.

What if I’m in debt?

You may still be able to switch depending on your meter type and circumstances. Comparing can help you see what’s possible — and your supplier can explain any restrictions.

Common mistakes when choosing an SVT (and how to avoid them)

Staying on SVT by default

SVTs are easy to drift onto after a fixed deal ends. Set a reminder to compare before your end date so you can choose proactively.

Comparing on monthly direct debit only

Some tariffs price differently depending on how you pay. Always check whether you’re comparing the right payment method for your household.

Ignoring standing charges

A lower unit rate isn’t everything. Standing charges matter, especially if you use less energy or you’re away from home often.

Not checking exit fees

If you’re switching away from a fixed deal early, exit fees can reduce or remove any savings. Check your tariff terms before you move.

Assuming the price cap is a “maximum bill”

The cap limits unit rates and standing charges for typical usage. Your actual bill still depends on how much gas and electricity you use.

FAQs: switching to a standard variable tariff in the UK

Is a standard variable tariff always more expensive?

Not always, but often. SVTs can be competitively priced at times, especially when fixed deals in the market are limited or priced higher. The only reliable way to know is to compare today’s options for your home.

Will I pay an exit fee if I move onto an SVT?

If you’re leaving a fixed tariff early to go onto an SVT, you may face an exit fee (depending on your supplier and contract). If your fixed deal has already ended and you’ve rolled onto the SVT, exit fees are usually not charged for leaving the SVT.

Is the Ofgem price cap the same everywhere in the UK?

The cap level can vary by region because network costs differ. Your supplier sets your specific unit rates and standing charges within the cap rules (where applicable).

Does comparing tariffs affect my credit score?

Comparing tariffs doesn’t affect your credit score. Some suppliers may run credit checks when you apply for certain payment methods, but comparison itself is not a credit application.

I’ve just moved house. Should I switch straight away?

After moving, you’ll normally be supplied by the existing supplier on a default tariff (often an SVT). It’s usually worth comparing once you have your opening meter readings and your account is set up, so you can switch smoothly and avoid billing issues.

Can I switch if I have a prepayment meter?

Yes, you may have options — but availability can depend on your supplier, meter type, and circumstances. Comparing helps you see what tariffs are available for prepayment in your area.
