Fast answer: how to compare electricity-only tariffs in the UK (2026)
For most homes, the best way to compare electricity-only deals is to look at your annual estimated cost using your postcode, meter type and payment method — then sanity-check the tariff’s unit rate (p/kWh), standing charge (p/day), contract length and exit fees.
Key takeaways (what usually matters most)
- Region affects price. Standing charges and unit rates vary by distribution area, so always compare using your postcode.
- Electricity-only ≠ “single fuel”. You might still have gas for heating, but your electricity tariff is separate.
- Standing charge can dominate for low users. If you use little electricity, a lower standing charge can be worth more than a slightly lower unit rate.
- Smart meters can unlock more options. Some tariffs (especially time-of-use) require a working smart meter.
- Pay attention to fees and restrictions. Exit fees, time-of-use rules, and discounts for Direct Debit can change the real cost.
Quick “best fit” guide
- Fixed tariff
- Often suits households that want budget stability for 12–24 months (but check exit fees).
- Variable tariff
- More flexible (usually no exit fee), but prices can change — sometimes quickly.
- Tracker tariff
- Price follows a published reference (supplier rules vary). Can be cheaper or more expensive depending on the market.
- Time-of-use
- Can benefit EV drivers or homes that can shift usage (dishwasher, washing machine) to off-peak.
Good to know: If you’re on a prepayment meter or have a restricted meter (such as Economy 7 / legacy multi-rate setups), your eligible tariffs may be different. We cover this below.
How to compare electricity-only tariffs (step-by-step)
Use this checklist before you request quotes. It helps you compare like-for-like and avoid switching to a deal that doesn’t fit your meter or lifestyle.
- Confirm your meter type. Single-rate, Economy 7/multi-rate, or smart meter with half-hourly readings. If you’re unsure, check your latest bill or online account.
- Choose your payment method. Direct Debit is often cheapest; pay-on-receipt and prepayment can cost more.
- Estimate annual usage (kWh). Bills usually show this. If not, use a rough estimate based on household size (see scenarios below).
- Compare both unit rate and standing charge. The cheapest unit rate isn’t always the cheapest overall if the standing charge is high.
- Check contract length and exit fees. Fixed deals may charge to leave early. Variable deals may be more flexible.
- Look for eligibility rules. Some tariffs require a smart meter, online account management, or certain payment methods.
- Read the tariff information label. This summarises pricing, fees, and key terms so you can compare fairly.
Tenant? You can usually switch the electricity supplier if you pay the bill, even if you rent. If bills are included in rent, you usually can’t switch because you’re not the account holder.
Two realistic cost scenarios (estimates)
These examples show why you should check both unit rate and standing charge. They are illustrative and use simplified assumptions.
Scenario A: Low-to-medium user (flat)
Usage: 2,000 kWh/year (electricity-only bill; heating may be gas or communal).
Tariff 1 (lower standing charge): 27p/kWh + 45p/day
Estimated annual cost: (2,000×£0.27) + (365×£0.45) = £540 + £164.25 = £704.25
Tariff 2 (lower unit rate, higher standing charge): 25p/kWh + 60p/day → £500 + £219.00 = £719.00
Scenario B: Higher user (family home)
Usage: 4,200 kWh/year (typical for a larger household).
Tariff 1: 27p/kWh + 45p/day → (4,200×£0.27) + (365×£0.45) = £1,134 + £164.25 = £1,298.25
Tariff 2: 25p/kWh + 60p/day → £1,050 + £219.00 = £1,269.00
At higher usage, a lower unit rate can outweigh a higher standing charge.
Assumptions used: Single-rate electricity; no discounts, cashbacks or bundling; no price changes during the year; Direct Debit pricing. Your actual prices depend on postcode region, meter, supplier and tariff terms.

Electricity-only tariff types: comparison table (UK)
Use this table to narrow down the type of tariff to compare. Exact prices, fees and eligibility vary by supplier and region.
| Tariff type | Price changes? | Typical exit fee | Who it can suit | Watch-outs |
|---|---|---|---|---|
| Fixed (12–24 months common) | Unit rate/standing charge fixed for term (supplier terms apply) | Often yes | Budget planners; anyone wanting stability | Early exit cost; may miss price drops |
| Standard variable | Supplier can change prices (often with notice) | Usually no | Short-term flexibility; people likely to switch soon | Less certainty; may be higher than the best fixed deals |
| Tracker | Moves with a published reference (rules vary) | Varies | People comfortable with price movement | Can rise quickly; read cap/limit terms carefully |
| Time-of-use (e.g. day/night rates) | Depends on tariff (can be fixed or variable) | Varies | EV drivers; shiftable usage; storage heating (where appropriate) | Peak rates can be high; needs the right meter setup |
| Prepayment (PAYG) | Depends on supplier/tariff | Often no | People who prefer pay-as-you-go budgeting | May have fewer deals; ensure top-up method suits you |
Decision checklist (printable)
- My current meter type is: single-rate / Economy 7 / smart / not sure
- I can pay by: Direct Debit / receipt of bill / prepayment
- I prefer: price certainty / flexibility / I’m comfortable tracking prices
- I’m happy to manage my account: online only / phone support needed
- I can shift usage off-peak (if time-of-use): yes / no
- I’ve checked: exit fees, contract length, eligibility and any discounts
Who electricity-only comparisons help most
- Often a good fit if…
- You don’t have mains gas, you’re on an all-electric home, you’re comparing an EV/time-of-use tariff, or you simply want to review your electricity costs independently.
- May be less useful if…
- Your landlord pays the bill, you’re tied to a complex communal energy setup, or your meter is restricted and needs specialist advice before switching.
Switching basics: In most cases, your electricity supply won’t be interrupted when you switch. You’ll still use the same wires and infrastructure — only the company billing you changes.
Costs, exclusions and common pitfalls (UK-specific)
Electricity-only tariffs can look similar on the surface. These are the most common reasons people end up on a deal that doesn’t work for them.
1) Standing charge surprises
Two tariffs can have similar headline rates, but a higher standing charge can cost more over the year — especially for low users or empty properties.
2) Meter mismatch
Economy 7/multi-rate and some legacy restricted meters may need specific tariffs. Switching to the wrong tariff can make heating or hot water far more expensive.
3) Payment method changes
If a quote assumes Direct Debit but you plan to pay on receipt of bill (or vice versa), your price can change. Always compare on your real payment method.
4) Exit fees and renewal rates
A fixed tariff can be good value, but check what it costs to leave early and what happens at the end of the term (often you move to a variable rate).
5) Time-of-use realism
Time-of-use only works if you can reliably shift usage. If most of your consumption stays at peak times, you may pay more overall.
6) “Green” tariff assumptions
Suppliers describe green electricity differently (e.g. renewable matching certificates). If this matters, read how the supplier defines it and what evidence they provide.
Prepayment households: If you’re struggling to top up or you’re in debt to a supplier, there may be extra steps before switching is possible. Independent help is available via Citizens Advice.
FAQs: electricity-only tariffs (UK homes)
Is electricity-only cheaper than dual fuel?
Not automatically. Dual fuel is simply having gas and electricity with the same supplier. Any “discount” varies, and you should still compare the electricity unit rate and standing charge on their own merits.
Can I switch if I rent?
Usually yes if your name is on the electricity bill and you pay the supplier directly. If your rent includes bills or the landlord is the account holder, you typically can’t switch.
Do I need a smart meter to get the best electricity-only tariff?
Not always. Many fixed and variable tariffs don’t require one. However, most time-of-use tariffs and some newer pricing models require a working smart meter capable of sending readings.
What if I’m on Economy 7 (two-rate electricity)?
Compare using your day and night usage split. If you can’t use much electricity off-peak, an Economy 7 tariff might cost more than a single-rate tariff. Always check your meter setup before switching.
Will switching interrupt my electricity supply?
In most cases, no. Your supply infrastructure stays the same. The switch is an administrative change between suppliers (unless there’s a complex meter issue that needs engineering work).
How long does it take to switch electricity supplier in the UK?
Timelines vary. Many switches complete within days, but it can take longer if there are meter details to resolve, debt/prepayment restrictions, or address matching issues. Your new supplier will confirm the dates.
What should I check before I agree to an electricity-only deal?
Confirm the unit rate (p/kWh), standing charge (p/day), contract length, exit fees, payment method assumptions, and any eligibility requirements (smart meter, online-only, paper billing charges).
What does “whole of market” mean in practice?
It means comparing across a broad range of suppliers and tariff types rather than a single provider. Availability can still vary by region, meter compatibility and supplier criteria.

How we assess electricity-only tariffs (and limitations)
This guide is designed to help UK households compare electricity-only tariffs in a way that reflects how bills are actually calculated.
- Core comparison factors: unit rate (p/kWh), standing charge (p/day), contract length, exit fees, payment method pricing, meter compatibility (single-rate vs multi-rate vs smart), and tariff structure (fixed/variable/tracker/time-of-use).
- Regional variation: we treat postcode/region as essential because distribution charges and standing charges differ across Great Britain.
- Usage sensitivity: we prioritise estimated annual cost and provide examples showing how low vs high usage can flip which tariff is cheaper.
- Eligibility checks: we highlight common restrictions (smart meter requirement, online-only management, Direct Debit assumptions, prepayment constraints).
- Limitations: we do not list “the cheapest tariff” on this page because prices change, suppliers update products, and availability depends on your details. Always confirm with the tariff information label and your supplier’s terms before agreeing.
Important: If your home has a complex meter setup (restricted hours, multiple MPANs, communal supply), get tailored advice before switching as the wrong tariff can increase costs.
