Why finding a cheap electricity supplier matters
Electricity is one of your biggest monthly outgoings. Even a small difference in your unit rate (p/kWh) or standing charge can add up to significant savings over a year. By regularly checking the market and switching to cheaper electricity tariffs when they become available, UK households can avoid paying more than they need to.
With the energy price cap changing several times a year and different suppliers competing for your business, it can be hard to keep track of what “good value” looks like. Our comparison tools and expert guides are designed to make it clear and simple.

Types of cheap electricity tariffs available in the UK
Different households have different needs. The cheapest electricity supplier for you will depend on how you use energy, how long you want to fix your rate for and whether you prefer flexibility or long-term certainty. Below are the main tariff types you’ll see when you compare.
1. Fixed-rate electricity tariffs
With a fixed tariff, your unit rate and standing charge are locked in for a set period, typically 12–24 months. This protects you from price rises during the contract.
- Great for budgeting and peace of mind.
- Exit fees may apply if you leave early.
- Not always the absolute cheapest rate, but more stable than variable tariffs.
2. Variable-rate electricity tariffs
Variable tariffs track the wholesale cost of electricity and the Ofgem price cap. Your rate can go up or down, typically with notice from your supplier.
- Often the supplier’s default or standard tariff.
- More flexibility — usually no exit fees.
- Can be cheap when wholesale prices fall, but can also increase.
3. Green and renewable electricity tariffs
If you want cheaper bills and a lower carbon footprint, look for green electricity suppliers. These tariffs use energy from renewable sources such as wind, solar and hydro, or match your usage with renewable certificates.
- Support the UK’s transition to net-zero.
- Costs are increasingly competitive with standard tariffs.
- Some suppliers offer 100% renewable electricity as standard.
4. Prepayment (pay-as-you-go) tariffs
Prepayment electricity meters use a key, card or smart top-up, letting you pay in advance for the energy you use.
- Helps you stay in control if you prefer to pay as you go.
- Historically more expensive, but capped by Ofgem.
- Cheap prepayment tariffs are available, especially on modern smart meters.
5. Economy 7 and time-of-use tariffs
If you use more electricity overnight, an Economy 7 or other time-of-use tariff can offer cheaper night rates in exchange for higher daytime rates.
- Best for homes with storage heaters or heavy night-time usage.
- Requires a compatible two-rate meter.
- Can be one of the cheapest options if you can shift your usage.
What affects the price of your electricity?
When you compare electricity suppliers, keep in mind that your total bill depends on several factors:
- Location: Different regions of the UK have different network costs.
- Usage: The more kWh you use, the more a cheap unit rate will save you.
- Meter type: Standard, smart, Economy 7 or prepayment.
- Payment method: Paying by monthly Direct Debit is usually cheaper.
- Tariff length: Longer fixes can be slightly higher, but protect against future rises.
Our comparison tool factors all of this in to highlight tariffs that are genuinely cheap for your home.
Dual fuel vs electricity-only: which is cheaper?
Many UK suppliers offer dual fuel tariffs, combining your gas and electricity into one plan. This can be convenient and sometimes cheaper overall, but it’s not always the best option.
When you compare cheap electricity suppliers with EnergyPlus, you can:
- See the cost of electricity-only tariffs.
- Compare them against dual fuel deals from the same or different suppliers.
- Mix and match — choose the cheapest electricity from one supplier and the cheapest gas from another.
We’ll clearly highlight which approach gives you the lowest combined bill based on your usage.
Can I switch if I’m in debt or renting?
Tenants: If you pay your energy supplier directly, you usually have the right to switch, even if your landlord suggests a preferred provider. Always check your tenancy agreement, but unfair restrictions can often be challenged.
Customers in debt: If you owe money to your current supplier, you may still be able to switch electricity supplier, especially if the debt is under 28 days old. Prepayment customers have specific rules that allow switching when you owe below a set limit.
If you’re unsure, start a comparison — we’ll explain your options based on your circumstances.
Tips for getting the cheapest electricity deal
Provide accurate usage details
The more accurate your electricity usage (from a recent bill or your online account), the more precise your comparison will be. This helps highlight tariffs that are truly cheap for your home, not just in theory.
Consider your payment method
Most suppliers offer discounts if you pay by monthly Direct Debit and opt for online billing. Choosing these options can unlock the very cheapest electricity prices.
Look beyond the unit rate
A low p/kWh rate can be offset by a high standing charge. Always compare the estimated annual cost for your usage — not just the individual rates.
Check exit fees and contract length
Some of the cheapest fixed tariffs come with exit fees. If you value flexibility, a slightly higher rate with no exit fee may work out better in the long run.
Use a smart meter if available
Smart meters give accurate readings and unlock certain cheap time-of-use tariffs. They also help you spot waste and take control of your energy habits.
Review your tariff regularly
When your fixed deal ends, you’ll often be moved onto a more expensive standard tariff. Set calendar reminders, or register for alerts, so you can switch again when cheaper suppliers become available.
Frequently asked questions about cheap electricity suppliers
The cheapest electricity supplier changes regularly as wholesale prices move and new tariffs launch. There is no single provider that’s always cheapest for every home. The only reliable way to find the lowest price for your property is to compare live tariffs using your postcode and usage.
Yes. The Ofgem energy price cap limits the maximum unit rates and standing charges suppliers can charge on default tariffs, but it does not cap the total bill you pay, and it does not stop suppliers offering cheaper fixed or promotional deals. Many households can still save by moving away from their standard variable tariff.
No. Your electricity is delivered through the same national network regardless of which supplier you pay. When you move to a cheap electricity supplier, the change is purely administrative — there is no interruption to your power supply.
To get the most accurate results, have the following to hand:
- Your postcode.
- Your current electricity supplier and tariff name.
- Your annual usage in kWh (found on your latest bill or online account).
- Your meter type (standard credit, smart, Economy 7 or prepayment).
If you don’t have your exact usage, we can still provide an estimate based on similar homes in your area.
Not necessarily. As renewable generation has grown across the UK, many green electricity suppliers now offer tariffs that are competitive with, or even cheaper than, standard deals. When you compare with EnergyPlus, you can filter for green tariffs and see which options offer the best combination of price and sustainability.
Most switches complete within 5 working days under Ofgem’s switching rules, though some suppliers may offer a cooling-off period. You’ll receive confirmation of your switch date, and you can continue to use electricity as normal while everything is processed.
