Figures are indicative. Your cheapest option depends on where you live, your meter and how you pay. Always check unit rates, standing charges and any exit fees.
Fast answer: what’s the cheapest electricity tariff after the July Ofgem review?
After Ofgem’s July price cap review, the cheapest electricity tariff for you is usually the one with the lowest estimated annual cost for your home once you include:
Unit rate (p/kWh)
What you pay for each unit of electricity you use.
Standing charge (p/day)
Daily cost for having the supply, even if you use no power.
Tariff terms
Exit fees, fix length, payment method, and eligibility.
Important: Ofgem’s price cap is not a cap on your total bill, and it does not mean all tariffs cost the same. It limits what suppliers can charge an average customer on a default (standard variable) tariff, expressed as unit rates and standing charges, which vary by region and payment method.
Key takeaways (UK-specific)
- Region matters: unit rates and standing charges differ across GB electricity distribution regions.
- Payment method matters: Direct Debit tariffs are often priced differently from prepayment (PAYG) meters.
- Meter type matters: single-rate, Economy 7/10 and smart tariffs can change what “cheapest” looks like.
- Standing charge can dominate: low users often benefit more from a lower standing charge than a tiny unit-rate saving.
- Fix vs variable: a fixed deal can be cheaper (or not) depending on current market pricing and any exit fees.
How to find the cheapest electricity tariff (after July’s cap update)
If you’re searching for the “cheapest electricity tariff after the Ofgem July review”, you’ll get the best result by comparing like-for-like using your own details. Use this sequence:
- Confirm your meter setup: single-rate, Economy 7/10, smart meter, or prepayment. Your tariff options (and prices) can differ.
- Get your current rates: find your unit rate(s), standing charge, and tariff name on a recent bill or in your online account.
- Check your annual usage (kWh): use your bill, your IHD/app if you have a smart meter, or an estimate if you’ve just moved.
- Compare total estimated annual cost: not just a headline unit rate. Standing charges and split day/night rates can flip the result.
- Read tariff terms: exit fees, price change rules (variable/tracker), contract length, and any discounts that can end.
Quick sense-check: if a deal looks cheaper but has a much higher standing charge, it may only suit higher electricity users. For low usage homes (e.g., small flats), standing charge differences can outweigh unit rate savings.
Two realistic scenarios (with numbers)
Scenario A: Low usage flat (single-rate)
Assumptions: 1,800 kWh/year electricity, Direct Debit, single-rate meter. Comparing two illustrative tariffs (not a promise of availability).
- Tariff 1 (lower unit, higher standing)
- 25p/kWh + 70p/day → annual estimate: (1,800×£0.25) + (365×£0.70) = £450 + £255.50 = £705.50
- Tariff 2 (slightly higher unit, lower standing)
- 26p/kWh + 45p/day → annual estimate: (1,800×£0.26) + (365×£0.45) = £468 + £164.25 = £632.25
Why it matters after July: when price cap levels change, suppliers can rebalance unit rates vs standing charges. Always compare the whole annual estimate.
Scenario B: Family home (single-rate)
Assumptions: 4,200 kWh/year electricity, Direct Debit, single-rate meter. Comparing illustrative tariff shapes.
- Tariff 1 (lower unit, higher standing)
- 25p/kWh + 70p/day → annual estimate: (4,200×£0.25) + (365×£0.70) = £1,050 + £255.50 = £1,305.50
- Tariff 2 (higher unit, lower standing)
- 26p/kWh + 45p/day → annual estimate: (4,200×£0.26) + (365×£0.45) = £1,092 + £164.25 = £1,256.25
Even here, the “headline cheapest unit rate” doesn’t automatically win. The break-even point depends on your usage and the standing charge gap.
Compare electricity tariffs for your home
Tell us a few details and we’ll help you compare available home energy options. This is a quote request — prices and availability vary by region, meter and supplier criteria.
Tip: If you have Economy 7/10 or a prepayment meter, mention it when we contact you. Those details can materially change which tariff is cheapest.
Compare your options after the July Ofgem review
The July Ofgem review updates the price cap level for default tariffs. But you can still choose between several tariff types. This table helps you decide what to compare first.
| Tariff type | How pricing changes | Typical upsides | Watch-outs |
|---|---|---|---|
| Standard Variable (SVT) / default | Can change; constrained by Ofgem price cap levels (unit rates/standing charges vary by region & payment method). | No lock-in; usually no exit fees; simple. | May not be cheapest; prices can rise at future cap updates; standing charges can be high for low users. |
| Fixed (e.g., 12 months) | Unit rate(s) and standing charge fixed for the term (subject to contract terms). | Budget certainty; can be cheaper than SVT if priced well. | Exit fees may apply; may miss future price falls; check what happens at end of fix. |
| Tracker | Price moves with an index/rule (supplier-defined), not the Ofgem cap level directly. | Can fall when markets fall; transparent rules (if clearly published). | Can rise quickly; not everyone wants day-to-day variability; may have minimum/maximum rules. |
| Time-of-use (smart tariffs) | Different rates at different times (e.g., peak/off-peak); may change per tariff rules. | Can be very good if you can shift usage (EV charging, flexible appliances). | Not always cheapest if you can’t shift usage; check peak rates and required smart meter. |
Decision checklist: who the “cheapest” tariff tends to suit
Often suits you if…
- You can pass a credit check and pay by Direct Debit.
- You know your approximate annual kWh, so you can compare fairly.
- You’re happy to switch online and keep an eye on renewal dates.
- You’re on a standard variable tariff and a competitively priced fix is available in your region.
- You have a smart meter and can shift usage (for time-of-use tariffs).
May not suit you if…
- You’re likely to move home soon and the deal has exit fees.
- You’re on prepayment and a tariff requires Direct Debit or a credit meter.
- You have Economy 7/10 and the “cheap” tariff assumes single-rate usage.
- You prefer price stability but are considering a tracker without understanding the pricing rule.
- You’re a very low user and the cheapest unit-rate deal has a high standing charge.
Renters: you can usually switch your electricity supplier if you pay the bill, even if you’re not the property owner. If bills are included in rent, you typically can’t switch — ask your landlord/agent.
Costs, exclusions and common pitfalls (read this before switching)
After a price cap review, it’s common to see headlines about “cheapest tariffs”. The details are where money can be won or lost. Here are the big gotchas to check.
Standing charge vs low usage
If you use relatively little electricity, a higher standing charge can wipe out a “cheap” unit rate. Compare annual estimates using your kWh.
Exit fees and moving
Many fixed tariffs have exit fees. If you might move, check whether fees are waived when you move home (supplier policies vary).
Economy 7/10 assumptions
Day/night splits matter. If you can’t shift usage to off-peak, an Economy 7 deal can cost more than a single-rate tariff.
Direct Debit vs prepayment
Some “best buys” assume Direct Debit on a credit meter. Prepayment customers can have different tariffs and eligibility requirements.
Discounts and intro offers
Some tariffs include time-limited discounts or bundled perks. Make sure you know when any discount ends and what prices revert to.
Timing around cap changes
A fixed deal cheaper than SVT today isn’t automatically “best” if future cap levels fall. Balance price certainty vs flexibility.
Not sure what you’re on? Your current tariff name, meter type and payment method should appear on your bill. If you’ve just moved in, you may be placed on a deemed/standard tariff — it’s still worth comparing once you have your first bill or meter readings.
FAQs
Does the Ofgem July price cap mean tariffs are cheaper?
Not automatically. The cap level can move up or down each quarter, and it applies to default tariffs (SVTs) rather than fixed deals. The cheapest tariff for you depends on your region, meter type, usage and the deals currently available.
Is the “price cap” a cap on my total bill?
No. It’s a cap on unit rates and standing charges for an average customer on a default tariff. Your total bill still depends on how much electricity you use.
Can I get a cheaper tariff if I have a prepayment meter?
Sometimes, yes — but options can be more limited and some tariffs require a credit meter paid by Direct Debit. If you can switch meter type, speak to your supplier first; eligibility and installation rules apply.
What if I’m in Scotland/Wales/England — does it change the cheapest tariff?
Yes, potentially. Electricity prices vary by distribution region, which doesn’t map neatly to national borders. Two homes with identical usage can pay different standing charges and unit rates depending on the local network area.
Should I fix after the July review?
Fixing can make sense if the best available fixed rate is lower than your current tariff’s likely cost over the term, and you’re comfortable with any exit fees. If you value flexibility (or expect prices to fall), a variable or tracker may suit better. Compare total estimated annual cost and read the terms.
How do I compare Economy 7 tariffs properly?
Use your actual (or best-estimate) day vs night split in kWh. Economy 7 can be cheaper if you use a meaningful share off-peak (often via storage heaters or EV charging), but peak rates can be higher.
Will switching affect my electricity supply?
Your physical supply doesn’t change. Switching is an administrative transfer. You’ll normally just need meter readings (or smart reads) and to set up payment with the new supplier.
I’ve just moved — can I switch straight away?
Usually yes, if you’re responsible for the bill. Take opening meter readings and find out who currently supplies the property. You may need your first bill or account setup before some suppliers can complete a switch.

How we assess “cheapest after the July Ofgem review”
We don’t label one tariff as universally cheapest, because the cheapest option depends on personal factors. Instead, this guide explains how to identify the cheapest tariff for your home after a price cap update.
- We focus on total estimated annual cost using: (unit rate × annual kWh) + (standing charge × 365).
- We account for UK-specific variation: region (distribution area), payment method (Direct Debit vs prepayment), and meter type (single-rate vs Economy 7/10 vs smart/time-of-use).
- We treat tariffs by structure (SVT, fixed, tracker, time-of-use) because the “best” choice can be about risk and flexibility, not just today’s price.
- We highlight terms that change outcomes: exit fees, end-of-contract changes, discounts, and eligibility requirements.
Limitations: The worked examples on this page use illustrative rates to show how the maths works. Market tariffs change frequently and availability differs by postcode, meter and supplier rules. Always confirm rates and contract terms before switching.
