What happens when my fixed energy tariff ends?

When your fixed energy tariff ends, your supplier will usually move you onto a variable tariff (often their standard variable tariff). Your unit rates and standing charge can change, so it’s worth comparing new fixed deals before the end date to avoid paying more than necessary.

Should I switch before my fixed tariff ends?

In many cases, yes—switching before your fix ends can help you secure a better rate and avoid rolling onto a higher variable tariff. Check your end date and any exit fees first; many tariffs have no exit fees in the final weeks of the contract.

Will I pay an exit fee if I leave a fixed tariff early?

Some fixed tariffs charge an exit fee if you leave before the contract ends. Check your latest bill, online account, or tariff terms to confirm the fee and whether it’s waived close to the end date. If you’re within the supplier’s no-penalty window, you may be able to switch without paying an exit fee.

How soon can I switch if my fixed energy deal is ending?

You can usually start comparing and switching several weeks before your fixed deal ends. Starting early gives you time to choose a tariff and reduces the chance of being moved onto a more expensive variable rate.

What is the best option when fixed tariff deals are ending soon in the UK?

The best option depends on your usage, region, and preferences. Many households look at new fixed deals for price certainty or compare competitive variable tariffs if rates are expected to fall. The most reliable way to decide is to compare quotes using your current unit rates, standing charge, and annual consumption (kWh).

Is a fixed energy tariff better than a variable tariff right now?

A fixed tariff can offer budget certainty because rates are locked for the term. A variable tariff can rise or fall, so it may be suitable if you want flexibility. Compare the total estimated annual cost (including standing charge) and consider whether you value price stability over flexibility.

How do I compare energy tariffs accurately?

To compare accurately, use your annual electricity and gas usage (kWh) from your bill (or your best estimate), then compare unit rates (p/kWh) and standing charges (p/day). Also check contract length, exit fees, payment method, and whether the tariff is fixed or variable.

Can I switch energy supplier if I’m in debt?

You may still be able to switch, but it depends on the type and amount of debt and whether you have a repayment plan. Some customers can switch through industry processes designed to help people move supplier while managing debt. It’s best to check your account status and speak to your supplier if unsure.

What information do I need to switch energy tariffs?

Typically you’ll need your postcode, current supplier and tariff details, and an estimate of your annual usage (kWh) for gas and electricity. Having your latest bill helps you compare like-for-like and choose the cheapest option for your household.

How long does it take to switch energy supplier in the UK?

Switching usually takes a few working days to a couple of weeks depending on the supplier and the switching process. You won’t lose supply—your gas and electricity keep flowing, and the changeover is handled between suppliers.

What should I do if my fixed energy tariff is ending soon?

Check your tariff end date, confirm whether there are exit fees, and compare available fixed and variable options based on your usage. If you find a better deal, start the switch early so you don’t default onto a potentially higher variable tariff. You can compare energy options at https://www.energyplus.co.uk/.

Why fixed energy tariff deals end — and what happens next

A fixed tariff is typically set for a defined period (for example, 12 or 24 months). When the term ends, suppliers usually move you to their default variable tariff unless you choose another deal. This is one of the most common reasons UK households see their monthly direct debit increase.

Your fix ends

Your contract term expires and your supplier issues end-of-tariff notifications (usually in advance).

You move to SVT

If you don’t pick a new tariff, you may roll onto a standard variable tariff (often not the most competitive).

Costs may change

Unit rates, standing charges and your direct debit can increase — especially in higher-use months.

Benefits of sorting your energy tariff before it ends

Searching early gives you more control. You can compare fixed deals ending soon in the UK against what’s available now, and plan a switch that fits your contract end date.

Avoid being rolled onto SVT

If your fix ends, doing nothing can mean landing on a tariff that isn’t aligned to your usage and payment method.

Budget with more confidence

A fixed tariff can help keep energy rates steady for the term (useful when prices are volatile).

Choose based on what matters

Price matters, but so do standing charges, exit fees, customer service and smart meter support.

Reminder: The cheapest-looking tariff isn’t always the cheapest overall. Standing charges and your actual usage have a big impact.

When should you switch if your fixed energy deal is ending soon?

For many UK households, the best approach is to start comparing several weeks before your fixed tariff ends. That gives you time to understand exit fees, compare rates and line up your switch date.

Check your end date on your latest bill, online account or contract summary.
Look for exit fees (and whether they reduce as you get closer to the end date).
Compare whole-of-market options for your postcode and payment method.
Pick a tariff that matches your usage (and consider standing charges, not just unit rates).
Confirm the switch timing so you don’t accidentally pay exit fees unnecessarily.

If you’re already out of contract: you can usually switch without exit fees. Comparing now can help you move off an SVT sooner.

What to check when comparing fixed tariff deals ending soon

If your fixed term is ending soon, it’s tempting to focus on the headline price. Use the checklist below to compare tariffs properly and avoid common pitfalls.

What to compare	Why it matters	Quick tip
Unit rates (p/kWh)	This is what you pay for each unit of gas/electricity used.	High usage? Unit rate often drives your annual cost most.
Standing charges (p/day)	A daily charge you pay regardless of usage.	Low usage? Standing charge can dominate the bill.
Exit fees	Fees for leaving before the fixed term ends.	Check if fees apply per fuel (gas and electricity).
Payment method	Direct debit, prepayment, or pay on receipt can change pricing.	Match tariffs to how you actually pay today.
Contract length	Longer fixes can offer stability but may reduce flexibility.	If you may move home, shorter terms can help.
Smart meter compatibility	Some tariffs or billing features work best with smart meters.	Not sure? We can still compare based on your current setup.

If you’re on Economy 7 / multi-rate

Make sure you compare like-for-like (day/night rates and standing charges). The “best” tariff depends on how much you use overnight.

If you’re prepay / pay-as-you-go

Availability can vary by region and meter type. Share your postcode in the form and we’ll focus on tariffs that fit prepayment options.

Common mistakes when a fixed energy tariff is ending

Waiting until after the end date

You could spend weeks on an SVT while you decide. Comparing ahead of time keeps you in control.

Ignoring standing charges

A slightly cheaper unit rate can be outweighed by a higher daily standing charge, especially for smaller homes.

Forgetting exit fees

Switching too early can cost more than it saves. It’s often about choosing the right timing, not just the right tariff.

FAQs: fixed energy deals ending soon (UK)

Will my supplier automatically renew my fixed tariff?

Usually, you won’t be automatically renewed onto the same fixed tariff. In many cases you’ll be moved to a standard variable tariff unless you select a new deal. Your supplier should contact you before the end date with options.

Is it worth fixing again?

It depends on current market pricing and what matters to you (budget stability vs flexibility). A fixed tariff can help you plan your costs, but it may include exit fees. Comparing whole-of-market options helps you make a decision based on your actual usage.

Can I switch if I’m in debt with my supplier?

In some situations you can still switch, but there may be restrictions depending on debt amount and meter type (for example, prepayment). If this applies to you, submit the form and we can help explain your options.

Will switching interrupt my gas or electricity supply?

Switching supplier should not interrupt your supply — the energy comes through the same pipes and wires. Your tariff and billing provider changes, not the physical supply.

How long does an energy switch take in the UK?

Timings vary by supplier and circumstances, but switches are typically completed within days to a few weeks. If you’re close to your fixed end date, lining up the switch is key to avoiding unnecessary time on an SVT.

What if I don’t have a recent bill?

That’s fine. Start with your postcode and contact details. We can still guide you on next steps and what to gather to firm up the comparison (such as annual consumption in kWh).
