Compare this week’s UK fix and fall energy tariffs
A fix and fall tariff (sometimes described as a “tracker with protection” or “capped variable”) aims to give you downside protection if wholesale prices rise, while still allowing your unit rates to move down if the market eases. Not every supplier offers these, and terms can vary a lot — so comparison matters.
EnergyPlus is a whole-of-market comparison service for home energy in the United Kingdom. Complete the form and we’ll match you to available fix-and-fall style deals based on your location, meter type and usage.
What you’ll see in your results
- Estimated annual and monthly cost for your usage
- Unit rates and standing charges where available
- Contract length, exit fees and any price protection cap
- Eligibility notes (e.g., smart meter, payment method)
Tip: Have your latest bill handy if possible. Your usage (kWh) helps us estimate costs more accurately than price-per-unit alone.
Why choose a fix and fall tariff?
Fix-and-fall style tariffs are designed for households that want more certainty than a standard variable but don’t want to be locked into a strict fixed rate if the market drops. The right choice depends on your appetite for risk, how long you plan to stay put, and whether you can tolerate short-term price movement.
Protection if prices rise
Many fix-and-fall deals include a cap or protection mechanism, helping reduce the shock of sudden increases (subject to tariff terms).
Potential to pay less if prices fall
Unlike a standard fixed tariff, your rates may move down with the market, so you’re not stuck paying yesterday’s price.
More flexibility than long fixes
Some plans have shorter commitments or lower exit fees — but always check the contract length and switching terms.
Better matched to real-life usage
Comparing using your estimated kWh can highlight tariffs with lower standing charges or unit rates that suit your home.
Whole-of-market visibility
Fix-and-fall options can be limited. A broad comparison helps ensure you’re not missing a better fit available in your region.
Clearer decision-making
Seeing caps, fees, and terms side-by-side reduces the risk of switching to a tariff that looks cheap but costs more over time.
How fix and fall energy tariffs work in the UK
The name “fix and fall” is used in different ways. In general, these tariffs aim to limit upward movement (or provide some form of price protection) while letting your rates decrease when the underlying index or market price reduces.
In practice, the supplier may link your unit rate to a benchmark or adjust prices periodically. Some products are closer to a capped variable; others resemble a tracker. Always read the tariff information before switching.
- We match your postcode to available tariffs for your region, meter type and payment options.
- You compare key terms such as standing charge, unit rate, cap/protection, contract length and exit fees.
- You choose a tariff and apply. Switching is usually handled by the supplier and your energy supply continues uninterrupted.
Fix vs variable vs fix & fall
| Tariff type | How prices change | Typical trade-off |
|---|---|---|
| Fixed | Unit rates stay the same for the term. | Certainty, but you may miss out if prices fall. |
| Standard variable | Supplier can change prices; often tracks broader market. | Flexibility, but less protection from rises. |
| Fix & fall | Can move down; upward movement may be capped or protected. | Balanced approach, but terms can be complex. |
Table is a general guide. Specific rules (caps, review periods and calculation methods) differ by supplier and product.
What to check before choosing a fix and fall deal
“Best” depends on your household. When you compare fix and fall energy tariffs in the UK, focus on the details that change your actual bill — not just headline rates.
1) The cap / protection mechanism
Check what is capped (unit rate, whole bill, or something else), how often prices are reviewed, and whether there are any exceptions.
2) Standing charge vs unit rate
Low unit rates can be offset by higher standing charges. This matters for low-usage households and flats.
3) Exit fees and contract length
If you want flexibility, look for short contracts and check whether there’s a fee to leave early.
4) Meter and payment eligibility
Some deals require a smart meter, are restricted by region, or differ for direct debit vs prepayment.
Common switching mistakes (and how to avoid them)
- Comparing on unit rate only: always consider the standing charge and your usage.
- Ignoring exit fees: a tariff can look good now but be costly to leave later.
- Not checking meter type: Economy 7, smart meters and prepayment can change availability.
- Forgetting end dates: set a reminder to review your tariff before it ends.
Regional pricing, meters and why your postcode matters
Energy prices can vary across the UK due to regional distribution costs, and availability can differ depending on your meter type and payment method. That’s why we start with your postcode — it helps us filter to tariffs you can actually get.
Different regions, different standing charges
Your electricity distribution region affects the standing charge and sometimes unit rates. Two households using the same kWh can pay different amounts.
Smart meters and time-of-use
If you have (or can get) a smart meter, you may see extra tariff types. Fix-and-fall style deals may still have eligibility rules.
Prepayment vs direct debit
Some tariffs are restricted by payment method. If you’re on prepayment, your available choices can be different.
Fix and fall tariffs: FAQs
Are fix and fall tariffs the same as a tracker?
Not always. Some are tracker-like (moving with an index), while others are variable tariffs with a cap or protection. Your comparison results should show the key mechanism and terms.
Will my bill definitely go down if prices fall?
It depends on the tariff rules and review periods. Some tariffs adjust monthly or quarterly; others only change under specific conditions.
Do fix and fall tariffs have exit fees?
Some do, some don’t. Exit fees and contract length vary by supplier. Always check the tariff information before you switch.
Is it safe to switch energy supplier?
Yes — your energy supply doesn’t stop during a switch. Your new supplier typically handles the process. Keep your meter readings and confirm your Direct Debit details.
Can I switch if I’m in debt with my current supplier?
Possibly. Eligibility depends on your supplier, the size of the debt and your payment arrangement. Use the form and we’ll show what’s available based on your details.
How do I know what’s “best this week” for me?
The best fix-and-fall deal depends on your postcode, usage, meter type and whether you want a cap, shorter term or lower standing charge. Comparing with your details is the quickest way to find the best fit.
