Compare cheaper alternatives to an EPG-linked tariff
The Energy Price Guarantee (EPG) is a government-backed mechanism that effectively limits the unit rates suppliers can charge for standard variable tariffs and some default tariffs, subject to your region, payment method and meter type. It doesn’t mean your bills are capped, and it doesn’t always mean you’re on the cheapest available deal.
If you’re asking, “Can I switch to a cheaper Energy Price Guarantee tariff?”—the key point is that you can often switch to a tariff with prices below typical EPG-linked levels (for example, a competitive fixed deal or a tariff with lower standing charges in your area). EnergyPlus is a whole-of-market comparison service for UK home energy, so you can see what’s available for your postcode.
Quick answer: In most cases, yes—you can switch supplier or tariff while EPG-linked pricing exists. The main things to check are exit fees (if you’re on a fixed deal), your meter type (standard, smart or prepayment) and your payment method (direct debit vs pay on receipt).
When switching is usually straightforward
- You’re on a standard variable tariff (often EPG-linked) and want to move to a fixed or cheaper variable option
- You have no exit fees (or the savings justify any fees)
- You’re not in debt to your current supplier, or you can repay/agree a plan
- You’re switching gas, electricity or both for a residential address in the UK

Not sure what tariff you’re on? No problem. Enter your postcode and we’ll help you find suitable options based on your property and meter type.
Important: The EPG affects typical unit rates, but your total bill depends on your usage, standing charges, tariff type, region and payment method. Always compare based on your own home and meter setup.
Why switch if I’m already on EPG-linked prices?
Lower standing charges
Some tariffs compete on standing charge rather than unit rate. If your usage is low or seasonal, a lower standing charge can matter.
Fix for predictability
A fixed tariff can protect you from price changes during the fixed period—useful for budgeting and avoiding surprises.
Better fit for your home
Smart meters, Economy 7, prepayment and region all affect what’s available. A tariff that suits your setup may beat typical EPG pricing.
Avoid loyalty penalties
Staying on an older default tariff can mean missing newer offers. Comparing keeps you aligned with current market options.
Switch without disruption
Your gas and electricity won’t be cut off when you switch. The change is administrative and handled by the suppliers.

How the Energy Price Guarantee affects your tariff
The Energy Price Guarantee is often misunderstood as a cap on bills. In practice, it affects the unit rates (what you pay per kWh) and can vary by region, meter type (including prepayment) and payment method. Your total cost still depends on how much energy your household uses and the standing charge you pay each day.
EPG-linked (often standard variable)
- Prices can move when the underlying cap/guarantee changes
- Usually no exit fee
- May not be the cheapest once the market becomes more competitive
Alternative tariffs (fixed/tracker)
- Fixed: stable unit rate for the fixed term
- Tracker: rate changes via an agreed formula/benchmark
- May include exit fees—worth checking before switching
EPG vs your actual bill: what to compare
Tip: If you can’t find your unit rates, take a photo/screenshot of your latest bill and look for “electricity supply charges” and “gas supply charges”. That’s what matters when comparing.
What you’ll need to switch (and what happens next)
Useful information to have
- Your postcode (to show region-specific prices)
- Meter type (smart/standard, prepayment, Economy 7)
- Payment method (Direct Debit or otherwise)
- Usage (kWh) or annual spend estimate (if you have it)
- Tariff end date and any exit fees if you’re fixed
How the switch typically works
- Compare available tariffs for your postcode and meter type
- Choose the tariff that suits your budget and risk preference (fixed/variable/tracker)
- Apply through EnergyPlus (no disruption to supply)
- Supplier handles the switch and notifies your old supplier
- Provide a meter reading (if requested) to ensure accurate final bill
Will I lose the EPG if I switch? The EPG is not a personal “membership” benefit. It’s a pricing mechanism that applies to eligible tariffs. If the tariff you switch to isn’t EPG-linked (e.g. a fixed deal), your price will be the one agreed in your new contract.
Will switching actually save me money?
Potentially—especially if your current EPG-linked tariff has higher standing charges for your region, or if the market offers competitive fixed deals. The most reliable way to know is to compare quotes using your postcode and (ideally) your usage.
If you use a lot of energy
Focus on unit rates. Even a small reduction in p/kWh can add up over a year.
If you use less energy
Standing charges can dominate. A tariff with a lower standing charge may be better even if the unit rate is similar.
If you’re risk-averse
A fixed deal can provide budget certainty—compare the premium (if any) against peace of mind.
A simple way to judge whether to switch
Households with smart meters: you may be offered additional tariff types (including smart or time-of-use options). These can be cheaper depending on when you use electricity.
Common mistakes when switching from EPG-linked pricing
Comparing only unit rates
Standing charges can change the outcome, especially for smaller homes and low usage. Compare total estimated cost where possible.
Forgetting exit fees
If you’re fixed, check any early termination charge. Sometimes it’s still worth switching—but calculate it first.
Choosing the wrong meter type
Economy 7 and prepayment tariffs can price differently. If you’re unsure, check your bill or compare with help via the form above.
Switching without a meter reading
Providing an accurate reading helps prevent billing issues. Smart meters can submit this automatically, but it’s good to double-check.
FAQs: switching to a cheaper tariff while the EPG exists
Is there an “Energy Price Guarantee tariff” I can choose?
Most households experience EPG-linked pricing through a standard variable tariff or default tariff structure. Suppliers may brand tariffs differently, but EPG is not usually a standalone product you “sign up” to. If you switch to a fixed deal, you’ll pay the fixed prices agreed in that contract.
Will I pay an exit fee if I leave an EPG-linked tariff?
Standard variable tariffs typically don’t have exit fees. Exit fees are more common on fixed deals. If you’re unsure, check your latest bill, your online account, or your contract summary.
Can I switch if I’m in credit or I owe money?
If you’re in credit, you should receive that credit back (often after your final bill). If you owe money, you may need to clear it or agree a repayment plan—rules vary by situation and supplier. Comparing still helps you understand your options.
Can I switch with a smart meter or prepayment meter?
Yes, often. Availability depends on your tariff type and supplier criteria. Some offers may require smart meter compatibility, and prepayment tariffs can differ by region and meter setup. Enter your postcode to compare relevant options.
How long does switching take?
Switching times can vary. In general, it’s an administrative process and your energy supply stays on. Your new supplier will confirm key dates and any actions needed (such as providing a meter reading).
Do I need my MPAN or MPRN to switch?
Not always. Your postcode and address are often enough to start a comparison. If required, your electricity MPAN and gas MPRN are found on your bill.
