How do I know when my current fixed tariff ends?

You can find your tariff end date on a recent bill, in your online account, or in the welcome email/contract from your supplier. Your supplier should also contact you ahead of the end date with renewal options.

Should I switch before my fixed energy deal ends?

Often, yes—because many customers who do nothing move onto an SVT, which can be more expensive. Comparing available fixed and variable tariffs before your end date can help you lock in a competitive rate or choose flexibility, depending on what suits your household.

Will I pay an exit fee if I switch early?

Some fixed tariffs include exit fees if you leave before the end date. However, in many cases you can switch without penalty in the final weeks of your fixed term (check your tariff terms). Always confirm any exit fees with your supplier before switching.

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

You may still be able to switch, depending on the type and level of debt and whether you pay by credit, prepayment, or have an agreed repayment plan. If you’re unsure, check with your current supplier and compare options that can accommodate your circumstances.

How far in advance can I switch before my fixed tariff ends?

You can usually start comparing and applying well before your end date. Many suppliers allow penalty-free switching in the final 49 days of a fixed deal, but terms vary—so it’s best to begin checking deals early and confirm any exit fee window.

What information do I need to compare fixed tariff deals ending soon?

You’ll typically need your postcode, current supplier/tariff details, payment method, and estimated usage (kWh) for gas and electricity. Having your annual consumption from a bill makes comparisons more accurate.

Is it better to choose another fixed tariff or a variable tariff?

A fixed tariff can offer price certainty for the fixed term, which many households prefer for budgeting. A variable tariff can offer flexibility, but rates can change. The best choice depends on your risk tolerance, budget, and how long you want price certainty.

How long does switching energy supplier take in the UK?

In many cases, switching can complete within around 5 working days, though timings can vary. You should not experience any interruption to your energy supply—only the billing and customer service change.

Will my energy supply be interrupted if I switch?

No. Switching supplier does not stop your gas or electricity supply. Your energy still comes through the same pipes and wires—only the company that bills you changes.

What happens if I do nothing when my fixed deal ends?

If you don’t choose a new tariff, you’ll usually be moved onto your supplier’s standard variable tariff (SVT). This can change over time and may be higher than fixed options available—so it’s worth comparing before your end date.

Fixed energy tariff deals ending soon in the UK

Q: What does it mean when a fixed energy tariff deal is ending soon?

It means the supplier’s fixed-rate tariff is close to its end date. When the fix ends, you’ll usually move to that supplier’s standard variable tariff (SVT) unless you choose a new deal. Checking end dates helps you avoid unexpected price changes and gives you time to switch or renew.

If your fixed deal is ending (or you’re about to come off a cheap fix), you could be moved onto your supplier’s variable tariff. Compare whole-of-market home energy deals with EnergyPlus and request a callback to switch at the right time.

Check deals ending soon When should I switch?

Home energy only. Switching depends on tariff terms, meter type and availability. We’ll explain your options before you decide.

Compare fixed deals before your tariff ends

When a fixed energy tariff deal ends, most UK households are moved onto their supplier’s standard variable tariff (SVT) unless you choose a new deal. If you’re within the switching window, you can often line up a new tariff so you avoid paying more than you need to.

EnergyPlus is a whole-of-market comparison service for home energy. Tell us a few details and we’ll help you compare options that match your meter and preferences, including:

Fixed tariffs (price certainty for a set period)
Variable tariffs (rates can change, usually linked to the SVT level)
Dual fuel (gas + electricity) or electric-only
Smart meters, traditional meters, and many Economy 7 setups (where available)

Tip: Even if your fixed deal ends soon, you may be able to secure your next tariff ahead of time. Check your contract terms for exit fees and the fee-free switching window.

Request your comparison (no obligation)

Are you on a deadline? If your fixed energy tariff ends in the next 60–90 days, it’s worth checking early – some suppliers allow you to secure a new tariff before your end date.

What happens when your fixed energy tariff ends?

In the UK, when a fixed tariff reaches its end date, you’re usually moved to your supplier’s default variable tariff (often the SVT). Your supplier should contact you before the end date, but it’s easy to miss emails or letters – and the first higher bill can be a nasty surprise.

1) You stay supplied

You won’t be cut off. Energy supply continues as normal. The change is typically the unit rates and standing charge.

2) Price certainty ends

A fixed deal protects you from some price changes for the term. Once it ends, your tariff can change with supplier pricing and market conditions.

3) Your monthly payment may shift

If you pay by Direct Debit, your supplier may review your payments based on expected annual usage and your account balance.

Good to know: If you switch supplier, your supply won’t be interrupted. Your energy comes through the same pipes and wires; only the billing and tariff change.

Why act before your fixed deal ends?

Avoid drifting onto a higher tariff

If your supplier moves you to an SVT when your fix ends, you could pay more than you need to for the same usage. Comparing early helps you make an informed choice.

Lock in price certainty (if suitable)

A fixed tariff can help budgeting by keeping your unit rates stable for the term. We’ll show what’s available and explain trade-offs like exit fees.

Choose what matters to you

Prefer a shorter fix, longer fix, no exit fees, or greener options? Whole-of-market comparison makes it easier to match tariffs to your household needs.

Reduce admin and uncertainty

Instead of trying to interpret tariff names and small print, we help you compare like-for-like: unit rates, standing charge, term length, and any fees.

Plan around your household changes

If your usage has changed (working from home, EV charging, heat pump, or a new baby), your tariff fit may have changed too. We’ll take your situation into account.

Best time to switch when your fixed tariff is ending

The best time depends on your current contract’s end date and whether your tariff has exit fees. Many fixed tariffs allow you to switch without paying exit fees in the final weeks of your contract – but policies vary by supplier and product.

Find your end date. Check your latest bill, online account, or supplier email/letter.
Check for exit fees and the fee-free window. If fees apply, see when they stop being charged.
Compare suitable deals. Use your postcode and meter details to find tariffs available to your home.
Time the switch. Aim for a switch that starts as your fix ends, so you minimise time on an SVT.
Submit meter readings (if asked). This helps ensure your final bill and opening bill are accurate.

How EnergyPlus helps you compare whole-of-market deals

We collect the right details (quickly)

Your postcode helps identify regional pricing and available tariffs. We may also ask about your meter type (e.g., smart, prepayment, Economy 7) and current supplier to improve accuracy.

You see clear comparisons

We focus on what matters: unit rates, standing charges, tariff length, payment method, and any exit fees or conditions – so you can compare like-for-like.

You stay in control

We’ll explain your options and answer questions. You decide whether to proceed. No pressure, and no need to call your current supplier unless you choose to.

Switching is straightforward

In most cases, switching supplier is managed for you by the new provider. You keep your supply, and the process is designed to be smooth for households.

Fixed vs variable tariffs: what’s the difference?

If your fixed energy tariff is ending soon, the decision often comes down to certainty vs flexibility. This table summarises the typical differences – your actual options depend on availability and your meter setup.

Feature	Fixed tariff	Variable tariff (incl. SVT)
Price certainty	Rates are usually fixed for the term (standing charge can vary by product terms).	Rates can change – supplier may update prices with notice.
Exit fees	Common, especially on cheaper deals; may be waived near end date.	Typically none on SVTs, but check tariff terms.
Budgeting	Easier to budget due to stable unit rates.	Harder to predict if prices change during the year.
Best for	Households wanting more certainty and willing to commit for a term.	Households prioritising flexibility or waiting for better fixed deals.

Important: Don’t compare deals on headline price alone. Standing charge, unit rates, payment method, and tariff rules can change the real cost for your household.

Common mistakes when a fixed energy deal is ending

Waiting until after the end date

You can still switch after your fix ends, but you may spend time on a variable tariff in the meantime. Comparing ahead of time helps you plan.

Not checking exit fees

Some fixes charge a fee if you leave early. If you’re close to the end, you may be able to switch in a fee-free window – but it’s not universal.

Comparing without meter context

Economy 7, prepayment, smart meters and regional network costs can affect availability and pricing. Whole-of-market comparison helps avoid false matches.

Ignoring the standing charge

A low unit rate doesn’t always mean a cheaper bill. Standing charge can make a significant difference – especially for low-usage homes.

If you’re unsure, submit your details and we’ll help you sense-check the options for your household.

FAQs: fixed energy tariff deals ending soon (UK)

Will my supplier automatically put me on the standard variable tariff?

In many cases, yes – when a fixed deal ends, suppliers usually move you onto a variable tariff unless you choose another product. Check your supplier’s end-of-fix communications and your tariff information.

Can I switch before my fixed tariff ends?

Often you can, but you may pay an exit fee if you switch too early. Many fixed tariffs include a fee-free switching window near the end date. We’ll help you understand your likely timings and options.

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

Timelines vary, but switching is typically designed to be straightforward. Your supply continues during the switch. The exact timing can depend on your meter type and supplier processes.

Do I need to contact my current supplier to cancel?

Usually, no. When you switch, the new supplier typically handles the transfer. You should still keep an eye out for your final bill and provide meter readings if requested.

What if I have a prepayment meter or Economy 7?

Tariff availability can differ for prepayment and multi-rate meters. Share your postcode and any details you know, and we’ll focus on options that match your setup and what’s available for your address.

Is it ever better to go onto a variable tariff?

It can be, depending on market pricing and your appetite for risk. Variable tariffs may offer flexibility and no exit fees, but prices can change. We’ll explain the pros and cons based on what’s available now.
