Time-of-use energy tariffs in the UK: are they worth it in 2026?
Time-of-use (TOU), agile and Economy 7 tariffs charge different electricity prices through the day. Whether they beat the July 2026 (Q3) price cap of 26.11p/kWh depends on how much of your usage you can shift to cheap off-peak hours.

Fast answer: are time-of-use tariffs worth it?
A time-of-use tariff is worth it when you can reliably move a big chunk of your electricity into cheap off-peak hours — typically overnight EV charging, a heat pump, storage heaters, or a home battery. In those cases the cheapest off-peak rates (often around 7p–10p/kWh on the best 2026 EV and smart tariffs) sit far below the July 2026 price cap of 26.11p/kWh, so the savings can be substantial.
It is usually not worth it if your home is busiest in the late-afternoon-to-evening peak (cooking, heating, screens) and you can’t shift much, because peak rates on TOU tariffs commonly run higher than the cap (often 30p–45p/kWh). The only way to know for sure is to compare against your real usage — get a free whole-of-market quote.
Check if a time-of-use tariff fits your home
Time-of-use energy tariffs charge different unit rates depending on the time of day (and sometimes day of week). They can be excellent value if you can shift a meaningful share of your electricity use into cheaper periods — for example overnight EV charging, running a dishwasher after 11pm, charging a home battery, or heating water off-peak.
But TOU isn’t automatically cheaper. With the July 2026 cap setting standard single-rate electricity at 26.11p/kWh (plus a 57.19p/day standing charge), a TOU tariff only wins if your discounted off-peak hours outweigh its more expensive peak rate. The quickest way to know is to compare options available for your postcode and your meter type.
What you’ll need to get an accurate comparison
- Your postcode (tariffs vary by region and network area)
- Whether you have a smart meter or a traditional meter
- Rough idea of when you use electricity (daytime vs evenings vs overnight)
- Any big flexible loads — EV, heat pump, storage heaters or a battery

So… are time-of-use tariffs worth it in the UK in 2026?
They can be, but only when the cheaper time bands line up with your real-life usage. Measured against the July 2026 cap of 26.11p/kWh, TOU tariffs tend to be worth it when:
- You can consistently use electricity overnight or in other off-peak windows (e.g. EV charging, a heat pump on a timer, washing, tumble drying, immersion heater, battery charging).
- You have (or can get) a smart meter sending half-hourly readings, which most modern TOU and agile tariffs require.
- You’re comfortable avoiding peak slots for flexible loads, especially during winter evenings when peak rates bite hardest.
They’re often not worth it if your household is busiest at peak times (cooking, heating, entertainment in the early evening) and you can’t move much usage — in that case a competitive fixed tariff at or just below the cap is usually the safer choice.
Who benefits most from time-of-use tariffs?
EV drivers
If you charge overnight, dedicated EV tariffs in 2026 offer off-peak rates around 7p–10p/kWh — roughly a third of the 26.11p cap. For a typical 10,000-mile-a-year driver that can mean three-figure annual savings on charging alone.
Heat pump homes
A heat pump scheduled to do most of its work in off-peak windows (and pre-heat the home before peak) pairs well with TOU and heat-pump-specific tariffs, cutting the cost of the largest electrical load in the house.
Electric hot water & storage heaters
Economy 7/10-style setups can perform well when your heating and hot water are designed to charge up off-peak. The longer, cheaper night window does the heavy lifting.
Solar + battery (where available)
A battery lets you import cheap off-peak electricity and discharge it through peak hours, sidestepping the priciest rates. (Note: GivEnergy entered administration in April 2026 — we don’t recommend that hardware; choose a supported brand.)
Flexible households (WFH, smart appliances)
If you can run laundry, dishwashers, dehumidifiers, or batch cooking outside peak periods, TOU can reward that flexibility — especially with appliance timers or a smart-home setup.
People who track usage
If you’re happy reviewing your app or in-home display and adjusting routines, you’re more likely to get value from TOU pricing. The data is your friend.

How time-of-use tariffs work (UK explanation)
A time-of-use tariff sets different electricity unit rates for different time bands. Some tariffs have two rates (day/night), while others use multiple bands (off-peak, shoulder and peak). A handful are fully dynamic ("agile") and change every half-hour based on wholesale prices. Your standing charge can also differ from standard tariffs.
Key point: A “cheap off-peak rate” only helps if enough of your kWh land in that window. If your peak rate is well above the 26.11p cap, shifting just a small amount may not be enough to win overall. As a rough guide, you usually need to move at least 30–40% of your electricity off-peak for a TOU tariff to beat a good single-rate deal.
Common UK TOU tariff types and how their rates compare
| Tariff type | How pricing works | Typical 2026 rate shape | Best for | Watch-outs |
|---|---|---|---|---|
| Economy 7 | Two rates: a night rate for ~7 hours and a higher day rate for the rest. | Night rate often well below 26.11p; day rate usually above it. | Storage heaters, overnight usage, some EV charging. | Day rate can exceed single-rate; night hours vary by region/meter setup. |
| Economy 10 | Off-peak split across day/night blocks (often 10 hours total). | Three cheaper windows spread across 24 hours; peak rate elevated. | Electric heating where extra daytime off-peak helps. | Not available everywhere; supplier choice can be narrower. |
| EV / smart TOU (multi-band) | A cheap fixed off-peak window (often a set 5–7 night hours) plus a standard or peak rate. | Off-peak roughly 7p–10p/kWh; day/peak around or above the cap. | EVs, batteries, heat pumps, flexible households. | Day rate can be higher than the cap; timings can change at renewal. |
| Agile / dynamic half-hourly | Rates change every 30 minutes, tracking wholesale prices (capped per Ofgem rules). | Very cheap (occasionally near-zero) overnight; pricey late-afternoon peaks. | People comfortable with variability, automation and monitoring. | Peaks can spike well above the cap in volatile markets; needs engagement. |
Rate shapes are illustrative of mid-2026 market patterns and vary by supplier, tariff and region. The 26.11p/kWh and 7.33p/kWh figures are the Ofgem July–September 2026 (Q3) price cap averages. Always check the exact tariff terms before switching.
A simple way to judge “worth it” before you switch
- Estimate your off-peak share: what percentage of your electricity can realistically happen in cheap hours? Aim for 30%+ to make TOU stack up.
- Check the peak rate vs the cap: a peak price well above 26.11p/kWh can cancel out gains if you still use lots of electricity at tea time.
- Compare standing charges: TOU tariffs may have a different standing charge from the 57.19p/day cap level, which affects low users most.
- Confirm meter compatibility: smart TOU and agile usually need a smart meter; Economy 7/10 needs the right meter configuration.
- Compare whole-of-market: prices and eligibility vary by supplier and region — use a comparison service rather than guessing.

Potential savings (and the most common mistakes)
Where TOU can save you money
- Overnight EV charging at ~7p–10p/kWh instead of the 26.11p cap rate
- Charging a home battery off-peak to cover peak-hour demand
- Shifting wet appliances (dishwasher, washing machine, dryer) to off-peak
- Running a heat pump or immersion heater off-peak where suitable
- Reducing peak usage during winter evenings when rates can be highest
Common mistakes that make TOU more expensive
- Not changing routines (usage stays in peak hours above the cap rate)
- Ignoring standing charges when comparing monthly cost
- Assuming Economy 7 helps everyone — it often needs high night usage to win
- Forgetting seasonal behaviour (more evening usage in winter)
- Overlooking the day rate, which on EV tariffs can sit above 26.11p/kWh
Quick rule of thumb
The lower your off-peak unit rate, the longer the off-peak window, and the more usage you can move into it, the easier it is to beat the July 2026 cap. If you can’t shift much, a competitive fixed tariff around the cap is often the lower-risk option. If you’re not sure, comparing quotes based on your details is the safest way to avoid a costly switch.
Regional considerations, meter types & eligibility
Why your postcode matters
Energy prices vary across Great Britain because the Ofgem cap and supplier pricing differ by region — the 26.11p/kWh and 57.19p/day figures are GB averages. TOU availability and off-peak rates can also differ by region. That’s why comparing with your postcode is essential.
Smart meter vs traditional meter
Most modern TOU and agile tariffs require half-hourly readings from a smart meter. Economy 7/10 typically needs a meter set up for multiple registers. If you’re unsure what you have, we can guide you after you submit the form.
Before you switch: a compatibility checklist
- Do you know your current tariff type? Single rate, Economy 7, or a smart/agile TOU product.
- Do you have electric heating, a heat pump or an EV? These often change the equation in favour of TOU.
- Can you shift usage? If your peak-time usage is “fixed” (cooking, family routines), be cautious.
- Are you on prepayment? Some TOU tariffs have different availability (we’ll check options for your situation).

Time-of-use tariffs UK: FAQs
What is a time-of-use energy tariff?
A time-of-use tariff charges different electricity unit rates at different times. You pay less in off-peak periods (often overnight) and more during peak periods, plus a daily standing charge. The best 2026 off-peak rates fall around 7p–10p/kWh, well under the July 2026 price cap of 26.11p/kWh, while peak rates can run above it.
Are time-of-use tariffs worth it in 2026?
They’re worth it if you can move a large share of your usage (roughly 30%+) into cheap off-peak hours — for example with overnight EV charging, a heat pump, storage heaters or a battery. If most of your usage stays in the evening peak, you may pay more than a fixed tariff at or just below the 26.11p cap. Compare against your real usage before switching.
Is Economy 7 the same as time-of-use?
Economy 7 is a traditional type of time-of-use tariff with two rates (a ~7-hour night rate and a higher day rate). Modern smart and agile TOU tariffs can have multiple bands or change every half-hour, but the principle is the same: reward shifting usage to cheaper times.
Do I need a smart meter for a TOU tariff?
Usually yes, especially for multi-band smart and agile tariffs that rely on half-hourly readings. Economy 7/10 can work on compatible multi-rate meters. Availability depends on the supplier and your setup.
Can a time-of-use tariff increase my bill?
Yes. If you don’t shift enough usage into off-peak periods, the higher peak unit rate (often above the 26.11p cap) and any different standing charge can mean you pay more overall than on a standard single-rate tariff.
Are TOU tariffs good for electric cars?
Often yes. EV charging is one of the easiest large loads to schedule into off-peak hours, and dedicated 2026 EV tariffs offer off-peak rates around 7p–10p/kWh — roughly a third of the cap rate. The best tariff depends on your mileage, charger power and off-peak window.
Do TOU tariffs suit heat pumps and home batteries?
They can be a strong match. A heat pump scheduled around off-peak windows, or a battery charged overnight and discharged through peak hours, lets you buy most of your electricity at the cheapest rates. Avoid GivEnergy battery hardware, which entered administration in April 2026, and choose a supported brand.
Will TOU affect my gas prices too?
No. TOU pricing applies to electricity only. Gas is charged at a single rate — under the July 2026 cap that’s 7.33p/kWh plus a 29.04p/day standing charge. Your final quote will show both fuels if you’re comparing dual fuel.
Is a whole-of-market comparison better for TOU?
Yes — TOU products vary widely by supplier, eligibility and region. A whole-of-market comparison shows which options you can actually get for your postcode and meter, rather than one provider’s headline off-peak rate.
