Compare energy deals when your fix ends
When a fixed rate energy deal ends, many UK households are moved onto their supplier’s standard variable tariff (often called the SVT). That can mean a higher unit rate and standing charge than your fixed deal — especially if your tariff was taken out before recent market changes.
EnergyPlus is a whole-of-market comparison service for home energy. Share a few details and we’ll help you compare available tariffs (including fixed and variable options) and understand your next steps — without the guesswork.
Tip: If you’re within the final weeks of your fixed term, it’s a good time to compare. Some suppliers allow switching with no exit fees once you’re near the end date, but terms vary.

What you’ll need (if available)
- Your current supplier and tariff name
- Whether you pay by Direct Debit or prepayment meter
- Rough annual usage (kWh) or a recent bill
Why comparing at the end of a fixed deal matters
Avoid rolling onto a higher rate
Many households move to an SVT automatically. Comparing helps you see if a new fixed tariff or alternative variable option suits you better.
See the real cost: unit rates + standing charges
A lower unit rate isn’t everything. We help you compare the full picture, including standing charges and payment method.
Switch with confidence
Switching usually doesn’t interrupt your supply. Your new supplier typically handles the transfer and notifies your current supplier.
Whole-of-market comparison service
Rather than relying on a single supplier, comparing across the market can reveal more suitable tariffs for your home and region.
Know your options if prices are volatile
If you’re unsure about fixing again, we can explain the trade-offs between fixed and variable tariffs based on your priorities.
Support for common situations

What happens when your fixed rate energy deal ends?
Your supplier should contact you before your fixed tariff ends. If you do nothing, you’ll normally be moved onto a default variable tariff. This is often the supplier’s standard offering, and while it’s subject to the Ofgem price cap (where applicable), it may still be more expensive than a competitive deal.
Typical timeline
- Supplier reminder: you’ll be told your end date and what your new rate could be.
- Your fixed term ends: your prices may change the next day.
- Automatic move (if no action): you’re placed on a variable tariff.
- You can still switch: even after the end date, you can compare and move to a new tariff.
What changes can affect your bill?
- Unit rates (pence per kWh) for electricity and/or gas
- Standing charges (daily fixed amount)
- Payment method (e.g., Direct Debit vs. pay on receipt)
- Tariff structure (single rate vs. Economy 7, smart time-of-use tariffs)
Good to know: Switching supplier typically does not require an engineer visit and should not disrupt your energy supply. You’ll continue to use the same pipes and wires; only the billing changes.
When should you switch at the end of a fixed deal?
The best time to act depends on your current contract terms, your end date and whether exit fees apply. Many fixed deals charge an early exit fee if you leave before the end date. However, some tariffs reduce or remove exit fees in the final period. Always check your agreement or the supplier’s message.
| Time to end date | What to do | What to watch for |
|---|---|---|
| 8–12 weeks | Start monitoring market rates and note your end date. | Exit fees may still apply if you switch immediately. |
| 4–6 weeks | Compare tariffs and shortlist options. Request a quote. | Supplier communications may include your expected new SVT prices. |
| 0–4 weeks | Often a practical time to arrange a switch if exit fees are reduced/removed. | Check exact end date and any final charges/credits. |
| After the end date | You can still switch—compare quickly if you’re on a variable tariff. | You may pay higher rates while you remain on the variable tariff. |
If you’re unsure: complete the form above and we’ll help you understand the practical next step based on your postcode and situation.
Fixed vs variable tariffs: what’s the difference?
Understanding the tariff types helps you choose what fits your household. Below is a simple guide to the most common options UK homes see when a fixed deal ends.
| Tariff type | How it works | Who it may suit | Key considerations |
|---|---|---|---|
| Fixed tariff | Unit rate and standing charge are set for a term (e.g., 12–24 months). | Households who want predictable pricing. | May include exit fees; check if rates are competitive for your region. |
| Standard variable (SVT) | Prices can change. Often where you land automatically when your fix ends. | Short-term stopgap while you compare. | Usually not the cheapest long-term; still worth comparing. |
| Tracker / indexed | Rates follow an index or formula (varies by supplier and product). | Those comfortable with price movement. | Understand how the tracking works and when it can change. |
| Time-of-use | Different rates at different times (often smart meter required). | People who can shift usage to cheaper times. | Check peak/off-peak rates carefully; not always cheaper overall. |

Common mistakes at the end of a fixed rate energy deal
Waiting for the first higher bill
If your fix ends, higher variable rates can apply immediately. Comparing early helps you avoid paying extra for longer than necessary.
Only comparing the headline unit rate
Standing charges can materially change annual costs. A slightly higher unit rate can still win if standing charges are lower (or vice versa).
Not checking exit fees or tariff end date
Switching too early can trigger fees. Switching too late can mean time on a variable tariff. Knowing your dates keeps you in control.
FAQs: end of fixed rate energy deal (UK)
Will my energy be cut off if I switch supplier?
In most cases, no. Switching normally changes billing and the supplier relationship, not the physical supply. Your gas and electricity should continue without interruption.
Do I have to stay with my current supplier when my fix ends?
No. You can usually choose a new tariff with your current supplier or switch to another supplier. Comparing whole-of-market options can help you find a better fit.
What is the Ofgem price cap and does it guarantee the cheapest price?
The price cap limits certain costs on default tariffs (for typical usage), but it doesn’t mean the tariff is the cheapest available. Many fixed and alternative tariffs can be priced differently, so it’s still worth comparing.
Will I pay an exit fee if I switch?
It depends on your current tariff terms and how close you are to the end date. Check your contract or supplier communications. If you’re unsure, submit the form and we’ll help you identify what to check.
Do I need my MPAN or MPRN to compare?
Not always. A postcode and basic details can be enough to start. Your MPAN (electricity) and MPRN (gas) can be helpful later for accuracy, especially if there are meter or address complexities.
I have a prepayment meter. Can I still switch?
Potentially, yes, but availability and pricing can differ by supplier and meter type. Comparing using your postcode is the best way to see what’s available for your home.
How long does an energy switch take?
Timelines vary. In many cases, switches can complete in days rather than weeks, but it depends on the supplier, meter type, and whether there are any issues to resolve.
