What is a fix and fall energy tariff?

A fix and fall energy tariff typically combines two features: you fix your unit rates for a set term (helping protect you from price rises) and you may be able to benefit if the supplier reduces prices during your contract (the ‘fall’ element). Always check the specific tariff terms, how/when any reductions apply, and whether there are exit fees.

How does the ‘fall’ part work on fix and fall deals?

On some fix and fall deals, your rates are fixed but can be adjusted down if the supplier drops prices, if Ofgem’s Price Cap falls, or if the tariff includes a review mechanism. The exact trigger varies by tariff, so confirm whether reductions are automatic, how often they’re reviewed, and whether both gas and electricity rates can decrease.

Are fix and fall tariffs cheaper than a standard variable tariff?

They can be, but it depends on current market rates, your usage, and the tariff’s standing charge and unit rates. A fix and fall tariff may offer budget certainty with potential savings if prices drop, while a standard variable tariff can track market movements but may rise unexpectedly. Compare the full yearly cost using your typical kWh usage before switching.

Do fix and fall energy deals have exit fees?

Many fixed-term tariffs (including fix and fall deals) can include exit fees if you leave before the end date. Some may offer fee-free switching within a certain window near the end of the contract. Check the tariff’s exit fee amount, the end date, and any conditions before you sign up.

Who should consider a fix and fall energy tariff in the UK?

Fix and fall tariffs can suit households that want predictable bills but still want the possibility of paying less if prices drop. They may be useful if you prefer budgeting certainty, are concerned about price rises, or want a compromise between fully fixed and fully variable pricing.

Can I switch to a fix and fall tariff if I’m currently in a contract?

You can usually switch, but you may have to pay an exit fee if you’re leaving a fixed deal early. If you’re near your contract end date, you may be able to switch without fees. Review your current tariff terms and compare potential savings against any exit fee.

What should I compare when choosing between fix and fall energy deals?

Compare unit rates (p/kWh), standing charges (p/day), contract length, exit fees, payment method discounts, and how the ‘fall’ mechanism is applied. Also consider customer service, billing options (direct debit vs. pay on receipt), and whether the tariff is available for your meter type (credit, prepayment, or smart meter).

How do I get a quote or switch on EnergyPlus?

To see available tariffs and potential savings, start your quote and compare prices on EnergyPlus. You’ll typically need your postcode, current supplier, and an estimate of your annual gas and electricity usage (or a recent bill). Once you choose a deal, switching is usually handled for you, with minimal disruption to your supply.

Will my energy supply be interrupted when I switch tariffs?

No—switching supplier or tariff should not interrupt your gas or electricity supply. The change is administrative and your energy continues to flow through the same pipes and wires. You’ll be informed of key dates and may be asked for meter readings around the switch date.

Compare fix & fall energy tariff deals in the UK

“Fix and fall” is a common way people describe tariffs designed to protect you from sudden price rises, while still giving you a route to benefit if prices drop. In practice, suppliers may label these as price promise, guarantee, cap-linked or tracker tariffs, or as fixed deals with downward price adjustments during the term.

EnergyPlus helps you compare whole-of-market home energy deals so you can weigh up cost, certainty, and exit fees. If you’re unsure what you’re currently paying, we can still estimate using typical usage and your meter details.

Tip: If you’re on a standard variable tariff (SVT), you’re typically affected by changes to the Ofgem price cap. A fix and fall-style option may suit you if you want more predictability but still want a fair way to benefit if the market moves down.

What are “fix and fall” energy tariff deals?

In the UK, “fix and fall” isn’t a single regulated tariff type. It’s a consumer shorthand for deals that aim to give you upside if prices drop while offering some protection if prices rise. Depending on the supplier and product, that could mean:

Tracker tariffs

Your unit rate moves up and down based on a published reference (often linked to the Ofgem price cap or wholesale market indicators). If the reference falls, your rate can fall too.

Fixed tariffs with a promise

Some fixed deals include a supplier “price promise” that may reduce your rate during the term if their equivalent deal price drops (rules vary and may be time-limited).

Cap-style protections

Certain products are structured so increases are limited, while decreases can still be passed on. Always check how the cap is applied and what triggers changes.

Important: A “fix and fall” outcome depends on the tariff rules. Some “fixed” deals do not drop in price at all during the term. Others may drop only under specific conditions. EnergyPlus helps you compare the terms clearly before you decide.

Why households choose fix & fall-style deals

If you’re deciding whether to fix, track, or stay on a standard variable tariff, the best choice usually comes down to how you feel about risk and how long you plan to stay put.

Potential to benefit if prices fall

Unlike a typical fixed tariff, tracker and promise-style deals can reduce your costs when the reference price drops (subject to the tariff rules).

Less “timing the market” pressure

If you’re worried about fixing at the wrong moment, a price-tracking option can feel more flexible than a long fixed term.

Clearer budgeting than full volatility

Some products change on set dates or within defined rules, which may be easier to plan around than open-ended price movements.

Option to avoid long exit fees

Many tracker tariffs have low or no exit fees, which can help if you expect to move house or switch again soon.

Better fit for smart monitoring

If you track usage closely (smart meter or regular readings), it’s easier to spot when a changing tariff is no longer competitive.

Whole-of-market choice

Comparing across tariff types can uncover better value than only looking at “fixed” offers from your current supplier.

Trade-off to watch: if prices rise, a tracker can become more expensive quickly. If you need certainty, a fixed tariff may still be the better fit.

How fix & fall-style tariffs work (in plain English)

Before choosing any deal, it helps to understand what can change, when it can change, and what happens if you want to leave early.

Identify the tariff “mechanism”. Is it fixed, tracker, or a fixed deal with a price promise? Look for wording about review dates, indexing or cap linkage.
Check unit rates and standing charges. Your total cost depends on both. A slightly lower unit rate can be offset by a higher standing charge (or vice versa), especially for low-usage homes.
Review exit fees and term length. If your plan changes (moving home, changing meter, switching supplier), fees can reduce the value of a “good” tariff.
Confirm meter and payment compatibility. Some tariffs are restricted by meter type (e.g., prepayment) or payment method.
Compare estimated annual cost. Use your kWh usage if you have it; otherwise use your bill amount and we can estimate.

Good to know: even “fix and fall” style tariffs can change through updates to standing charges, changes to the reference price, or changes at agreed review points. Always read the key terms before switching.

Fix vs tracker vs standard variable (SVT): what’s the difference?

Use this table as a quick guide. Exact features vary by supplier and product.

Tariff type	What changes?	When can it change?	Best for
Fixed	Unit rate usually stays the same for the term (standing charge may still vary depending on terms).	Typically fixed for 12–24 months, with defined end date.	People wanting predictable costs and less price volatility.
Tracker	Unit rate follows a reference price (can go up or down).	Daily, monthly, or at set review points (depends on product).	Households comfortable with change and watching the market.
SVT (price cap-influenced)	Supplier can change prices; in many cases the Ofgem cap affects typical prices.	Often changes in line with cap updates and supplier decisions.	Short-term flexibility; people who don’t want a contract term.
“Fix and fall” style	Varies: can be tracker-based or fixed with downward adjustments under conditions.	Usually at defined review points or when the reference falls.	People wanting a balance: some protection with a route to benefit from falls.

Cost clarity: for a true comparison, focus on estimated annual cost using your usage (kWh) and region, not just the headline unit rate.

Eligibility: who can get fix & fall-style home energy deals?

Availability depends on supplier criteria and your household setup. When you compare with EnergyPlus, we’ll help match you to tariffs that fit your circumstances.

Meter type

Credit meters: widest choice.
Smart meters: may unlock more options and easier readings.
Prepayment: choice can be narrower; comparison is still worthwhile.

Payment and account factors

Some deals prefer Direct Debit.
Credit checks may apply for certain payment methods.
If you’re in debt with a supplier, switching rules may differ.

Moving home? If you expect to move within the next 6–12 months, look closely at exit fees and whether the tariff can be transferred to your new address.

Common mistakes when choosing fix & fall energy tariffs

Focusing only on the unit rate

Standing charges can make a big difference, particularly for smaller homes or lower usage. Compare total estimated annual cost.

Assuming “fixed” means it will fall

Many fixed tariffs don’t reduce if the market drops. If you want the ability to fall, check whether there’s an explicit promise or tracking mechanism.

Ignoring exit fees

A low headline price can be less attractive if you’ll likely switch again soon. Always balance savings against potential fees.

Not checking how often prices can change

Tracker tariffs can change daily, monthly or quarterly. Make sure the change frequency matches your comfort level.

Comparing with the wrong baseline

If you’re currently on SVT, your comparison should reflect your actual rates and region, not a generic national average.

Forgetting dual fuel vs single fuel

Gas + electricity is often convenient, but not always cheapest. Compare both dual-fuel and separate supply options where possible.

Fix and fall energy tariff deals UK: FAQs

Are “fix and fall” tariffs guaranteed to go down?

No. The phrase is informal. Some tariffs can fall (e.g., trackers or fixed deals with specific promises), but others are fully fixed for the term. Always check the tariff’s rules for when and how prices can change.

Is a tracker tariff the same as a fix and fall deal?

Often, yes in practical terms: a tracker can go up and down. But a “fix and fall” deal could also be a fixed tariff with a supplier promise to reduce prices under defined conditions. The name varies; the mechanism matters most.

What should I compare first: standing charge or unit rate?

Compare the estimated annual cost using your usage, then check the split between standing charge and unit rate. If your usage is low, standing charge changes can have a bigger impact on your total bill.

Can I switch if I have a smart meter or prepayment meter?

In many cases, yes. Smart meters can help make switching smoother, and prepayment customers can still have options (though the range may be smaller). We’ll match tariffs to your meter type when you request quotes.

Do fix and fall tariffs have exit fees?

Some do, some don’t. Fixed tariffs commonly include exit fees; many trackers are fee-free, but not always. If you may switch again soon, exit fees should be a key part of your decision.

How quickly can my price change on a tracker?

It depends on the product. Some update daily; others monthly or at set review points. If you want fewer changes, consider a fixed tariff or a tracker with less frequent reviews.

Still unsure? Go back to compare options and we’ll help you identify which type fits your home.
