Price cap applies to default variable tariffs, not fixed deals. Savings depend on your region, meter type and usage. For domestic customers only.
Compare the cheapest home energy tariffs available in your area
After a price cap change, the best-value tariff for your home can shift quickly—especially if you’re on a standard variable tariff (SVT) or coming to the end of a fixed deal. EnergyPlus helps you compare whole-of-market home energy tariffs using the details that matter: your postcode region, meter type and estimated usage.
To find “cheapest”, we consider the annualised cost (unit rates + standing charges) so you can judge value beyond headline rates. If you have a smart meter, we can also highlight tariffs that may suit your pattern of use.
Tip: The Ofgem price cap is a limit on the unit rates and standing charges suppliers can charge on SVTs, not a cap on your total bill. Your bill still depends on how much energy you use.
Already on an SVT? After a price cap change, SVT rates can move up or down in line with the new cap. Comparing fixed deals and tracker tariffs can reveal better value—especially if your current rates sit near the cap limit.
Why compare after the Ofgem price cap change?
Rates shift by region
The cap level differs across the UK because network costs vary. “Cheapest” in one postcode can be mid-pack in another.
Standing charges matter
A low unit rate can be offset by a higher standing charge. We help you compare total annual cost for your usage.
Fixing can protect your budget
If you prefer predictable bills, a fixed tariff can reduce uncertainty for the term (subject to any exit fees).
End of fix? Don’t roll onto SVT
When a fixed deal ends, many customers move to an SVT automatically. Comparing before that happens can help avoid higher rates.
Tariff types have expanded
Beyond standard fixed deals, suppliers may offer trackers or smart tariffs that better match your use.
Switching is usually seamless
In most cases there’s no interruption to your supply. Your new supplier handles the switch and updates your account.
What the price cap change means for your energy bills
The Ofgem energy price cap limits what suppliers can charge for unit rates (pence per kWh) and standing charges (pence per day) on default tariffs (including standard variable tariffs). When the cap changes, suppliers can adjust SVT rates to reflect the new limits.
Key points to remember
- It’s not a cap on your total bill—using more energy still costs more.
- The cap level varies by region and by payment method (e.g. Direct Debit vs prepayment).
- Fixed tariffs are not capped in the same way, so they can be lower or higher than SVT rates.
- Standing charges can significantly affect low-usage households and flats.
If you’re asking “what’s the cheapest tariff after the cap?”
There isn’t one single cheapest tariff for everyone. The cheapest deal depends on your postcode, meter (credit, prepay, smart), and annual consumption. Comparing with your details is the fastest way to see what’s genuinely cheapest for your home.
What “cheapest” usually looks like (and what to check)
When the price cap changes, suppliers often reprice their SVTs and review fixed offers. The cheapest available tariffs for many households tend to share a few traits—but always verify the full cost breakdown.
| Tariff feature | Why it matters | What to look for |
|---|---|---|
| Unit rates (p/kWh) | Main driver of cost for medium/high usage households. | Compare electricity and gas unit rates separately; watch for day/night rates if applicable. |
| Standing charges (p/day) | Can dominate the bill for low-usage homes. | Check your region’s standing charge; compare across tariffs even if unit rate is lower. |
| Tariff type | Determines how often your rate can change. | Fixed (price certainty), Variable (changes), Tracker (moves with an index). |
| Exit fees | Can reduce flexibility if cheaper deals appear. | If you may switch again soon, prefer low/no exit fees. |
| Discounts & incentives | May affect your first-year cost but not ongoing value. | Focus on ongoing rates and annual cost; treat incentives as a bonus. |
Practical shortcut: If you don’t know your exact usage, you can still compare using a reasonable estimate. Your supplier can confirm your annual kWh on your bill, or via your online account.
Fixed vs variable after a cap update: which is cheapest?
The cheapest tariff type depends on market pricing at the time you switch. Here’s how to evaluate options after a price cap change without relying on guesswork.
Fixed tariffs
- Price certainty for the term (commonly 12–24 months)
- Can be cheaper than SVT if suppliers price competitively
- May include exit fees if you leave early
- Best for budgeting and avoiding surprises
Variable / SVT / tracker tariffs
- Rates can change (SVT aligns with cap limits; tracker follows an index)
- Usually more flexible, often no exit fees
- May fall when the cap drops, but can rise at the next update
- Best if you value flexibility or expect better deals soon
Rule of thumb: Compare the annual cost based on your usage and region, then consider whether exit fees and term length still make it the right deal for you.
How switching works with EnergyPlus
Switching energy supplier is typically straightforward. In most cases, your supply stays on and your new supplier coordinates the process.

- Compare whole-of-market tariffs including unit rates, standing charges, term length and exit fees.
- Choose a tariff that fits your budget and risk preference (fixed vs variable).
- Apply to switch. Your new supplier normally handles the admin and keeps you updated.
- Provide meter readings when asked, so your final bill and new account start accurately.
No disruption
Your gas and electricity supply continues as normal during the switch.

Common mistakes to avoid when hunting the cheapest tariff
Comparing unit rates only
A tariff with slightly higher unit rates can still be cheaper overall if the standing charge is lower for your region and meter type.
Ignoring tariff end dates
If your fixed deal ends soon, you may be moved onto an SVT. Set a reminder and compare early so you can choose rather than default.
Overlooking exit fees
A low-rate fixed tariff might include exit fees that make switching again costly if prices fall or better deals appear.
Using the wrong usage figures
If possible, use your annual kWh from a recent bill. This produces a more accurate “cheapest tariff” ranking for your household.
Regional and meter considerations (UK homes)
Energy pricing isn’t one-size-fits-all. The same named tariff can cost different amounts depending on where you live and how you pay.
Postcode region
Distribution network costs vary. Always compare with your actual postcode to see accurate standing charges and unit rates.
Payment method
Direct Debit deals may differ from prepayment or pay-on-receipt options. Compare like-for-like for your situation.
Meter type
Smart, prepay and legacy meters can affect eligibility for certain tariffs. We’ll only show available deals for your setup.
Electric-only homes: If you don’t have mains gas (common in flats or rural areas), the “cheapest” approach often focuses on electricity unit rates and standing charges, and potentially smart tariffs if you can shift usage to cheaper times.
FAQs: cheapest energy tariffs after the price cap change
Does the price cap mean everyone pays the same?
No. The cap sets maximum unit rates and standing charges for default tariffs, but the exact rates differ by region and payment method. Your total bill also depends on usage.
Are fixed deals cheaper than the capped SVT?
Sometimes. Fixed deals can be priced below, similar to, or above SVT rates depending on market conditions. Comparing your postcode and usage is the most reliable way to see which is cheapest for you.
Can I switch if I’m on a prepayment meter?
Often yes, but tariff availability can be different. Some suppliers offer fewer prepay tariffs, and eligibility can depend on your meter setup. Compare with “prepayment” selected to see relevant options.
Will switching affect my supply?
In most cases, no. Your gas and electricity are delivered via the same networks. Switching changes the supplier billing you, not the physical supply to your home.
What information do I need to compare accurately?
Your postcode, fuel type and payment method are a good start. For greater accuracy, use your annual consumption in kWh from a recent bill and confirm your meter type (standard, smart, or prepayment).
What if I’m in a fixed contract with exit fees?
You can still compare. If exit fees apply, include them in your decision by weighing the fee against expected savings over the remainder of the term.
