What does it mean when fixed energy tariff deals are ending?

It means certain fixed-rate energy tariffs are being withdrawn or are no longer available to new customers. If you’re on one of these tariffs, you may still keep your rate until your fix ends, then you’ll usually move to your supplier’s standard variable tariff unless you switch or choose a new deal in advance.

Will my bill go up if my fixed tariff ends?

It can. When a fixed deal ends, many households are moved onto a standard variable tariff, which may be higher than your fixed rate. Checking the options before your end date can help you avoid an unexpected increase and potentially secure a better rate.

When should I switch energy if my fixed deal is ending?

You can usually agree a new tariff ahead of time. A good rule is to start reviewing your options in the weeks leading up to your fixed end date so you have time to compare rates and lock in a deal before moving onto a variable tariff.

Is there an exit fee for leaving a fixed energy tariff early?

Some fixed tariffs include an exit fee if you leave before the contract ends, but not all do. Check your tariff terms or your latest statement, and if you’re close to the end date, many suppliers waive exit fees during a final window—confirm this with your supplier.

How do I know when my fixed energy tariff ends?

Your end date is typically shown on your online account, welcome pack, or recent bill/statement. Suppliers also usually contact you before your fix ends with details of what happens next and what options you have.

What’s the difference between a fixed tariff and a variable tariff?

A fixed tariff locks in your unit rates and standing charge for the length of the contract, giving predictable pricing. A variable tariff can change (up or down) over time, often reflecting market conditions or price-cap changes.

Can I switch energy suppliers if fixed deals are ending?

Yes. If a tariff is being withdrawn, you can still compare available deals and switch supplier if it suits you. Switching typically won’t interrupt your supply—only your billing and tariff change.

Energy comparisons are based on the details you provide. Prices, availability and savings vary by region, meter type and usage.

Your fixed energy tariff is ending — what should you do?

When a fixed energy tariff ends, most UK suppliers move you onto their standard variable tariff (SVT) unless you choose a new deal. SVTs can be fine for short periods, but many households prefer the predictability of a fixed rate or a better value variable option.

EnergyPlus helps you compare whole-of-market home energy tariffs across the UK. Use the form to request a comparison and we’ll highlight suitable options based on your postcode, meter type and preferences (e.g., fixed vs variable, green options).

What happens when a fixed energy deal ends in the UK?

For most UK homes, when your fixed tariff reaches its end date you’ll typically be moved to your supplier’s standard variable tariff (SVT). Your supply continues as normal — the main change is the unit rate and standing charge you pay.

You won’t be cut off

Your gas and electricity keep running. Ending a fixed tariff is a pricing change, not a supply interruption.

Costs can change

Your new rates may be higher or lower than your old fix. Comparing tariffs helps you see what’s available for your postcode and meter type.

Key terms to know (quick glossary)

Fixed tariff: unit rates (and sometimes standing charges) are fixed for a set period.
SVT (standard variable tariff): price can change; often the default when your fix ends.
Standing charge: a daily charge for being connected to the network.
Unit rate: the price per kWh of gas or electricity you use.

Best time to act if your fixed deal ends soon

Timing matters because you may want to avoid early exit fees while also avoiding longer periods on an SVT. The right moment depends on your contract terms and the deals available at the time you compare.

When	What to do	Why it helps
6–8 weeks before end date	Check your current tariff end date, exit fees, and current rates on your bill.	Gives you time to compare and avoid rushed decisions.
Inside your exit-fee-free window	Request a comparison and shortlist tariffs that match your needs.	You can switch without paying an early exit fee (subject to your terms).
On or just after end date	Compare immediately to reduce time on SVT if it’s not right for you.	Helps you regain price predictability sooner.

Reminder: If you’re unsure about exit fees, check your welcome email, tariff terms, or your online account. If you tell us your end date, we can factor it into your options.

Common mistakes when a fixed energy tariff ends

Waiting for a “perfect” deal

Energy prices and tariff availability move. Comparing now helps you understand your real options for your postcode today.

Ignoring standing charges

Low unit rates can be offset by higher standing charges. Always look at both when you compare.

Assuming one tariff suits everyone

Household usage patterns differ. A tariff that works for a low-usage flat may not suit a larger home.

Forgetting meter readings

Accurate readings reduce billing issues at the switch point—especially if you don’t have a smart meter.

FAQs: fixed energy tariff deals ending soon (UK)

Will my bills go up when my fixed deal ends?

They can do. If you move onto an SVT with higher unit rates or standing charges than your fix, your costs may increase. Comparing tariffs helps you see current options for your home.

Do I have to stay with my current supplier?

No. You can choose a new tariff with your existing supplier or switch to another supplier. Your energy supply stays on during a switch.

Can I switch before my fixed tariff ends?

Often yes, but there may be an exit fee if you leave early. Check your tariff terms. Some suppliers waive exit fees near the end of a fixed deal, depending on the contract.

Is a fixed tariff always better than a variable tariff?

Not always. Fixed tariffs offer predictability, while variable tariffs can be flexible. The best choice depends on your household usage, budget preferences and the deals available at the time you compare.

Does my postcode affect energy prices?

Yes. Network costs vary by region, which can affect standing charges and unit rates. That’s why a tailored comparison uses your postcode.

What if I have a prepayment meter?

You may have fewer tariff options than credit meters, but there are still choices. We’ll consider meter type as part of your comparison.
