Find the cheapest fixed tariff for your home — compared to the price cap
There isn’t one single “cheapest fixed energy tariff” for everyone. The lowest-cost fixed deal depends on your region, meter type (including smart, prepay or Economy 7), payment method, and how much energy you actually use. EnergyPlus compares fixed tariffs from across the market and shows you the options that could be cheapest for your household — including how they stack up against the Ofgem price cap.
Tip: The Ofgem price cap limits the unit rate and standing charge suppliers can set for a typical variable tariff — it’s not a cap on your total bill. If your usage is higher (or lower) than average, the best fixed tariff for you may look different.

What “cheapest fixed energy tariff” means after the price cap
After an Ofgem price cap change, many households search for the cheapest fixed tariff to lock in certainty. But “cheapest” isn’t just the lowest headline unit rate. To choose well, you need to look at the total expected cost for your household and the terms of the fix.
Total annual cost (not just unit rates)
The cheapest option for you is usually the tariff with the lowest estimated yearly bill for your usage, including the standing charge.
Exit fees & flexibility
A low price can come with exit fees. If prices fall, a flexible fix (or a shorter term) may work out better.
Compatibility (meter + payment)
Not every cheap fixed deal is available for prepay, Economy 7, or some smart meter setups. We filter by your details.
Good to know: The Ofgem price cap applies to default variable tariffs (and certain prepayment tariffs). A fixed tariff can be priced below or above the cap depending on wholesale costs and supplier strategy.
Fixed tariff vs Ofgem price cap: what you’re actually comparing
When people say they want a fixed tariff “after the Ofgem price cap”, they usually mean: “Now the cap has changed, is there a fixed deal that will cost me less — and should I lock it in?” Here’s how to compare apples with apples.
| Feature | Price-capped variable tariff | Fixed energy tariff |
|---|---|---|
| Price changes | Can change when the cap changes (and sometimes in between for certain elements). | Unit rates and standing charge are fixed for the term (subject to contract terms). |
| Budget certainty | Lower certainty — costs can rise or fall with future cap reviews. | Higher certainty — easier to plan monthly payments. |
| Exit fees | Usually none. | Often applies if you leave early. Amount varies by supplier and tariff. |
| Who it can suit | Those who want flexibility or expect prices to fall. | Those who value predictability, or who find a fix below their variable option. |
Important: A fixed tariff can still lead to a higher total bill if your usage increases significantly — fixing locks the rates, not the amount you consume.
How to find the best fixed deal after a price cap change
If the cap has just moved, the market can shift quickly. Use this simple process to identify the cheapest fixed energy tariff that’s actually available for your home.
- Use your postcode first to ensure regional pricing is correct (standing charges vary by distribution area).
- Match your meter type (standard, smart, Economy 7, prepay). A great-looking deal may not apply to your setup.
- Compare total annual cost rather than just the unit rate. Standing charge can change the outcome.
- Check the fix length (e.g. 12, 18 or 24 months). Longer fixes may cost more for certainty.
- Review exit fees and decide how much flexibility you want if prices drop.
- Time your switch: if you’re near the end of a fix, you can often line up a new tariff without disruption.
Why the cheapest fixed tariff varies by region, meter and payment method
Energy prices in Great Britain aren’t uniform. Two households using the same amount of gas and electricity can see different costs due to regional network charges and tariff eligibility rules. That’s why a whole-of-market comparison is essential if you’re trying to beat the price cap.
Postcode regions & standing charges
Standing charges and unit rates can differ by distribution region. A fixed deal that’s “cheapest” in one area may be mid-pack in another. Always compare using your actual postcode.
Meter type & tariff eligibility
Prepay and Economy 7 customers often have different tariffs available. Some fixes are Direct Debit only. We help you filter to deals you can actually switch to.
If you’re on Economy 7 or a smart meter
Multi-rate meters can be great for overnight usage (storage heaters, EV charging), but “cheap” depends on your day/night split. When you compare fixed tariffs, check whether the tariff is single-rate or multi-rate, and whether your supplier allows your meter configuration.
Not sure what meter you have? Choose “Not sure” in the form. We’ll show options and highlight where meter type could affect eligibility or price.
Common mistakes when choosing a fixed tariff (and how to avoid them)
Comparing only unit rates
Standing charge can make a “low unit rate” deal cost more overall. Compare the estimated annual bill.
Ignoring exit fees
If you might move home or expect prices to drop, heavy exit fees can reduce savings. Check them before you switch.
Choosing the longest fix by default
A longer fix may cost more for certainty. Consider 12–18 months if you want a balance of price and flexibility.
FAQs: cheapest fixed energy tariffs after the Ofgem price cap
Is there a fixed tariff that’s always cheaper than the price cap?
No. The price cap affects variable tariffs, and fixed deals are priced by suppliers based on wholesale costs and competition. Sometimes a fixed tariff is cheaper than a price-capped variable option; other times it’s higher but offers certainty. The most reliable way to find the cheapest fixed option is to compare using your postcode and meter details.
Does the Ofgem price cap apply to fixed tariffs?
Typically, no. The cap is designed to limit the rates on default variable tariffs (and certain prepayment tariffs). Fixed tariffs are contract products with their own rates and terms.
Will switching disrupt my gas or electricity supply?
In most home switches, your energy supply continues as normal. You’re changing who bills you, not the pipes or wires. You’ll usually keep the same meter, and your supply shouldn’t be interrupted.
Can I switch if I’m in debt to my current supplier?
It depends on your setup and supplier. Some customers can still switch, while others may need to agree a plan first (particularly on prepayment arrangements). Compare tariffs anyway — we’ll show what’s available and you can check eligibility during the application.
What if I’m near the end of my current fixed deal?
Many suppliers move you to a variable tariff when your fix ends. Comparing before then can help you avoid rolling onto a potentially higher rate. When you choose a new fix, check if exit fees apply for leaving early.
How do you decide which fixed tariff is “cheapest” for me?
We prioritise tariffs by estimated annual cost using your postcode, meter type and payment method, then surface key terms (like exit fees and fix length). That way you can pick the best balance of price and flexibility.
