Compare fix and fall energy tariffs for your home
If you’re searching for the best fix and fall energy tariff deals in the UK, the “best” option usually depends on your postcode, current supplier, meter type (credit, prepayment or smart), and whether you prefer stability or flexibility. Fix and fall tariffs are designed for households that want a degree of price protection but also want a route to pay less if prices move down.
Use the form to tell us the essentials. We’ll use your details to guide you towards tariffs that match your preferences — including checking the important parts of any fix-and-fall offer such as exit fees, unit rates, standing charges and the conditions that trigger a price drop.
Quick tip: Two tariffs with the same “headline” saving can cost different amounts over a year because standing charges vary by region. Always compare the estimated annual cost as well as the unit rate.

Already on a fixed deal? If you have exit fees, it may still be worth comparing. We’ll help you check whether switching now or waiting makes sense.
What is a fix and fall energy tariff?
A fix and fall energy tariff is a type of deal where your price is protected (like a fixed tariff), but you may also benefit if the supplier reduces prices during your contract. The exact mechanism varies by supplier: some reduce rates automatically when they cut their standard variable tariff; others apply reductions at set review points; and some provide a one-off price decrease when certain conditions are met.
Fixed (price certainty)
Your unit rates and standing charges are typically set for the contract term. This can help budgeting.
Fall (potential reductions)
If the supplier lowers prices, you may be moved to the lower rate without needing to switch.
Terms matter
Not all deals “fall” the same way. It’s essential to check how and when reductions apply.
Why households choose fix and fall tariffs
Fix and fall tariffs can suit homeowners and renters who want protection against sudden increases but don’t want to feel “locked in” if the market improves. Here are common reasons people compare them.
Budgeting confidence
More predictable costs than standard variable tariffs, useful if your payments are tightly managed.
Less “rate regret”
If prices drop, you may benefit without starting a new switch (depending on the tariff rules).
A practical middle ground
Often chosen by people who don’t want fully variable pricing but still want a route to pay less later.
Potentially fewer switches
If reductions apply, you might not need to switch again as quickly — but always re-check near renewal.
Clearer risk limits
Compared with fully variable, your maximum rate is typically capped for the contract duration.
Useful if you’re watching the market
Some households prefer a deal that can improve while they keep an eye on future switching opportunities.
How to find the best fix and fall deal (in plain English)
To identify good fix and fall tariff deals in the UK, you need to compare more than a single “pence per kWh” figure. A tariff can look cheap on unit rates but cost more overall due to a higher standing charge — especially depending on your region.
EnergyPlus helps you compare with the details that matter for real household bills.
- Tell us your postcode so we can reflect local standing charges and availability.
- Share contact details so we can send options and answer questions about tariff terms.
- Compare like-for-like using estimated annual cost, contract length and fees.
- Check the “fall” rules — when reductions apply and what triggers them.
- Switch with confidence once you’re happy with the total cost and conditions.
Household-only note: This page is focused on home energy (domestic supply). If you’re looking for business energy, tariff structures and eligibility can differ.
What to check before choosing a fix and fall tariff
The quality of a fix and fall tariff comes down to the full set of terms and your household’s usage. Use the checklist below to compare deals properly.
| What to compare | Why it matters | What “good” can look like |
|---|---|---|
| Estimated annual cost | Shows the likely total cost for your household, not just one rate. | Lower total cost at your usage, with clear assumptions. |
| Unit rates (electricity & gas) | The price per kWh drives most of the bill for higher-usage households. | Competitive rates with no confusing add-ons. |
| Standing charge | Can make a big difference for low-usage homes and varies by region. | Reasonable standing charge for your area. |
| Contract length | Affects how long you’re tied to the rates and conditions. | A term that matches your preference (e.g., 12 months vs longer). |
| Exit fees | You may pay a fee if you switch before the contract ends. | Low or no exit fees, or fees that you’re comfortable with. |
| “Fall” mechanism | Determines whether (and when) you actually benefit if prices drop. | Clear triggers and timing, applied automatically where possible. |
| Payment method & meter compatibility | Some tariffs are limited to Direct Debit, smart meters, or certain meter types. | Matches your household setup without forced changes. |
Common mistake: comparing only the unit rate
If your usage is low, the standing charge can dominate. If your usage is high, small unit-rate differences can add up fast.
Common mistake: assuming all “fix & fall” terms are identical
Always read how reductions are applied. Some deals reduce only certain components, or only at specific points in time.
Eligibility and regional considerations (UK homes)
Fix and fall energy tariff availability can vary across the UK and by household setup. Here’s what can affect which deals you’ll see.
Your postcode & region
Standing charges and unit rates can vary by region, so “best” depends on where you live.
Meter type
Some suppliers limit particular tariffs to smart meters or have different pricing for prepayment meters.
Dual fuel vs single fuel
Dual fuel can be convenient, but the best overall price may come from separate suppliers.
Tip for renters: You can usually switch your energy supplier if you pay the bills, but check your tenancy agreement and ensure the account is in your name.
Fix and fall energy tariffs UK: FAQs
Are fix and fall tariffs cheaper than standard variable?
They can be, but not always. The total cost depends on your postcode, usage, and how competitive the supplier’s rates are. The “fall” feature may help if the supplier reduces prices during your term, but you should still compare estimated annual cost.
Do I automatically get the lower rate if prices fall?
It depends on the tariff terms. Some apply reductions automatically; others only at scheduled review points, or only when specific conditions are met. Always check the tariff’s “fall” clause and whether both unit rate and standing charge can change.
Are there exit fees on fix and fall tariffs?
Often, yes. Exit fees vary by supplier and contract length. If you might switch again soon, compare deals with lower exit fees, or factor the fee into your expected saving.
Is a fix and fall tariff good for low-usage households?
It can be, but low-usage households should pay close attention to standing charges. A slightly higher unit rate may be fine if the standing charge is lower in your region.
Can I switch if I have a smart meter or prepayment meter?
In many cases, yes. However, not every supplier offers every tariff to every meter type. Availability can also vary by region. Using your postcode is the quickest way to see what’s realistic for your home.
How quickly can I switch?
Switching times can vary by supplier and circumstances (for example, meter checks or debt on a prepayment meter). Once you choose a tariff, you’ll be given an estimated timeline and next steps.
