Find the cheapest fix-and-fall energy tariff for your home
“Fix and fall” usually means locking in a fixed tariff now but keeping the flexibility to switch again if prices drop later. Some households use this as a strategy rather than a single product: fix to protect your budget, then review regularly and move to a cheaper deal when it appears.
EnergyPlus helps you compare across the wider UK market (where available) so you can weigh up: unit rates, standing charges, exit fees, contract length, and whether a tariff suits your meter (including smart meters and prepay where supported).
Tip: The “cheapest” tariff isn’t only about the headline rate. A lower unit rate can be offset by a higher standing charge depending on your usage. We’ll ask a few details to estimate your annual cost and identify best-value options.
What you’ll need (takes about 2 minutes)
- Your postcode (to check local distribution region)
- Your name and contact details (to send your comparison and next steps)
- Optional: current supplier/tariff info if you have it handy

UK-specific guidance
Standing charges and unit rates vary by region. Your postcode helps us reflect local network costs and availability.
Fits your risk level
If you want budget certainty, fixed deals can help. If you can tolerate price movement, tracker/variable options may suit you better.

We’ll guide you through what to check before switching: contract end dates, exit fees, and whether you’re on a smart or prepay meter.
What does “fix and fall” mean for UK energy bills?
In UK home energy, “fix and fall” is usually shorthand for a practical plan:
- Fix now to protect your household budget with a set unit rate and standing charge for a defined term.
- Monitor the market (or set reminders) in case cheaper tariffs appear or price conditions change.
- Switch later if it becomes worthwhile—while checking any exit fees and the difference in total annual cost.
Important: Not every fixed tariff is suitable for a fix-and-fall approach. The key factor is the exit fee (and how soon you might need to leave). A low exit fee—or a shorter term—can keep you flexible if better deals appear.
When “fix and fall” can make sense
- You want certainty and you’re worried about near-term price increases.
- You can commit for a period, but you also want the option to switch if the market softens.
- You’re happy to review tariffs before your fixed term ends and plan ahead for renewal.
When it may not be right
- Your current deal has high exit fees or you’re within a period where leaving costs more than you’d save.
- You use very little energy—standing charges can dominate the cost difference.
- You don’t want to review again for a long time (a longer fixed term may suit you more).
Fixed, variable, tracker: what to compare
If you’re searching for the cheapest fix and fall energy tariff deals in the UK, it helps to compare tariff structures as well as price. Here’s a practical overview.
| Tariff type | How it works | Pros | Watch-outs |
|---|---|---|---|
| Fixed | Unit rate and standing charge stay the same for the contract term. | Budget certainty; protection if prices rise. | Exit fees can limit “fall” flexibility; not always cheapest if prices drop. |
| Variable (SVT or variable deal) | Prices can change (often with notice). Standard Variable Tariffs (SVTs) are common after a fix ends. | More flexibility; often no exit fee. | Less certainty; may be more expensive than competitive fixed deals. |
| Tracker | Price tracks an index (supplier-defined, e.g., wholesale-related) and can move regularly. | Can benefit when prices fall; transparent movement rules. | Bills may rise quickly; not ideal if you need stable monthly payments. |
| Time-of-use (e.g., Economy 7) | Different rates at different times (day/night). Often tied to specific meters. | Cheaper off-peak if you can shift usage (storage heaters, EV charging). | Can cost more if most energy is used at peak times; ensure the tariff matches your lifestyle. |
What to prioritise for “cheapest”: compare the annual cost estimate (based on your usage), then check the standing charge, unit rates, term length and exit fees. If you expect to switch again, exit fees matter more.
How to judge if a fix-and-fall deal is actually cheaper
Two tariffs can look similar, but cost different amounts over a year. Use this checklist when comparing electricity, gas or dual fuel:
1) Compare total annual cost
Look beyond p/kWh. The cheapest tariff depends on how much energy your home uses. A deal with a lower unit rate can still be worse value if the standing charge is higher.
2) Check standing charge differences
Standing charges vary by region. If you’re a low user (e.g., smaller flat), a high standing charge can outweigh a “cheap” unit rate.
3) Factor in exit fees
For fix-and-fall strategies, exit fees are crucial. If you switch early, fees can cancel out the savings from moving to a cheaper tariff later.
4) Mind contract end dates
Many households drift onto an SVT when a fix ends. Set a reminder 4–6 weeks before your end date so you can compare again without rushing.
Common comparison mistakes (and how to avoid them)
- Comparing only one fuel: dual fuel can be cheaper, but not always. Check gas and electricity separately too.
- Ignoring meter type: prepay and Economy 7 have different options. Always compare like-for-like.
- Assuming “cheapest” stays cheapest: energy prices move—review periodically if you want to “fix and fall”.
- Not checking payment method: direct debit tariffs can differ from cash/receipt of bill options.
If you’re not sure how much energy you use, you can still start a comparison with your postcode and contact details. We can help you estimate usage from your household and heating type when discussing options.
Eligibility and practical switching considerations
Who can switch?
- Most UK households can switch electricity, gas or dual fuel.
- If you rent, you can usually switch as long as you pay the energy bill and your landlord isn’t supplying energy as part of the rent.
- If you have debt with your current supplier, switching may be limited depending on circumstances and meter type.
What can affect available deals
- Region: distribution charges vary across the UK.
- Meter: standard credit, smart, Economy 7, or prepay can change the tariff list.
- Payment method: direct debit vs other payment methods can affect pricing.
On a fixed tariff already?
You can still compare. Before switching, check your current contract end date and any exit fees. If you’re close to the end, waiting may reduce fees—while still allowing you to plan your next fix (or switch to a tariff that can benefit if prices fall).
FAQs: cheapest fix and fall energy tariffs
Is there a specific “fix and fall” tariff product?
Usually, no. It’s more often a switching approach: choose a fixed deal for stability, then review again if the market offers a cheaper tariff. Some tracker tariffs can benefit from falling prices, but they don’t provide the same price certainty as a fix.
What makes a fixed tariff “cheap” in practice?
A cheap fixed tariff is one with a lower estimated annual cost for your usage. That depends on unit rates and standing charges in your region. The best-value deal for a high-usage household can differ from the best-value deal for a low-usage home.
Do exit fees always apply on fixed deals?
Not always, but many fixed tariffs include exit fees if you leave before the end of the term. If you’re planning a “fix then fall” strategy, compare exit fees carefully and weigh them against potential savings from switching later.
Will I lose supply when I switch?
No—switching supplier shouldn’t interrupt your gas or electricity supply. Your energy still comes through the same network; only the company billing you changes.
Is it cheaper to switch gas and electricity together?
Sometimes. Dual fuel can be convenient and may reduce cost, but it’s not guaranteed to be the cheapest overall. Comparing both together and separately helps you find best value.
Can I compare if I’m on a prepay meter?
Yes, though available tariffs can be more limited depending on supplier and meter type. Submit your details and we’ll help identify what’s available for your home and whether moving to a credit meter is an option.
How often should I review tariffs for a fix-and-fall approach?
A practical cadence is every 3–6 months, and always 4–6 weeks before your fixed term ends. Review more often if market conditions change quickly—but avoid switching purely on headlines; compare total annual cost and any exit fees.
