What is an evening-rate (off-peak) electricity tariff?

An evening-rate (off-peak) tariff is an electricity plan with cheaper unit rates during set evening hours. If you can shift energy-heavy use—like EV charging, laundry, or dishwasher cycles—into those hours, you can reduce your overall bill. Always check the exact off-peak window and the peak rate you’ll pay outside it.

Are cheap evening tariffs good for EV charging at home?

Yes—if you regularly charge in the evening window, a cheap evening-rate tariff can significantly cut your cost per mile. Pairing an off-peak tariff with a smart EV charger helps schedule charging automatically, so you consistently hit the cheaper rate without changing your routine.

What should I compare when choosing an evening-rate energy tariff?

Compare: (1) the off-peak time window (start/end times), (2) off-peak unit rate, (3) peak unit rate, (4) daily standing charge, (5) contract length and exit fees, and (6) whether a smart meter is required. The best tariff depends on how much electricity you can move into the evening period.

Do I need a smart meter for cheap evening-rate tariffs in the UK?

Often, yes. Many time-of-use (evening/off-peak) tariffs require a working smart meter to accurately record usage by time band. If you don’t have one, check whether the supplier will install it and how long setup takes before you switch.

What are the risks of switching to an evening-rate tariff?

The main risk is paying more at peak times if you don’t shift enough usage into the evening window. Review your typical routine (cooking, heating, hot water, and daytime appliance use) and estimate whether off-peak savings outweigh any higher peak rate and standing charge.

How can I maximise savings on an evening-rate tariff?

Schedule high-consumption tasks during the off-peak window: EV charging, washing/drying, dishwasher, immersion heater or hot-water boosts (where safe and appropriate), and battery storage charging (if you have it). A smart EV charger can automate charging to start when the cheaper rate begins.

Can I use a smart EV charger to automatically charge at the cheapest evening rate?

Yes. Many smart EV chargers let you set schedules (or integrate with apps) so charging starts and stops within your off-peak evening period. This helps improve conversion of cheap-rate hours into real savings—without manually plugging in at specific times. Learn more about EV charging options at https://www.energyplus.co.uk/ev-charger/.

Are evening-rate tariffs better than overnight EV tariffs?

It depends on when you can charge. Overnight tariffs can be ideal if your car is plugged in all night. Evening-rate tariffs can suit households that get home earlier and prefer to charge in the evening. Compare the off-peak window length and price, plus peak rates, to find the best match for your routine.

Fast answer: what counts as a “cheap evening rate” in the UK?

In practice, UK tariffs marketed as having cheap evenings usually fall into one of these types:

1) Evening off-peak windows

A lower unit rate for a set window (often late evening to night). Best if you can shift usage into that window.

2) EV/“smart” time-of-use tariffs

Cheaper electricity when you schedule/automate charging (sometimes with an app). Usually needs a smart meter.

3) Legacy multi-rate meters (e.g., Economy 7)

Traditionally cheaper overnight (not always “evening”). Works for storage heaters; less ideal if most use is daytime.

Key point: a cheap evening rate can be offset by a higher daytime unit rate and/or a higher standing charge. The “best” tariff depends on when you use electricity, your meter, your region, and how you pay.

Key takeaways (quick scan)

Most people benefit only if they can move a meaningful chunk of usage into the evening/off-peak window (often EV charging or a heat pump running later).
Smart meter often required for the cheapest time-of-use tariffs; Economy 7/10 needs the right meter setup.
Always compare the full bill: standing charge + day rate + evening/off-peak rate + any peak windows.
Check tariff rules: app control, compatible charger/vehicle, minimum off-peak hours, and whether export rates (solar) change.

How evening-rate tariffs work (in plain English)

You pay different unit rates at different times: For example, a lower rate in the evening/night and a higher rate the rest of the day. Standing charge usually stays the same every day.
Your meter must record usage by time: Most modern time-of-use tariffs need a working smart meter. Older multi-rate meters (e.g., Economy 7) can also work if correctly configured.
You benefit when you shift usage: If most of your electricity is used outside the cheap window, you can end up paying more—even if the off-peak rate looks great.

Two realistic UK scenarios (with numbers)

These examples are illustrative estimates to help you judge whether a cheap evening rate could work for you. Your actual prices depend on supplier, region and the tariff’s exact hours.

Scenario A: EV driver charging mainly in the evening

Home use: 3,600 kWh/year electricity
Of which off-peak: 40% (EV charging scheduled in the evening/night)
Tariff 1 (single-rate): 26p/kWh, standing charge 55p/day
Tariff 2 (evening/off-peak): 35p/kWh day, 12p/kWh off-peak, standing charge 60p/day

Estimated annual cost (energy + standing):
Single-rate: (3,600×£0.26)=£936 + (365×£0.55)=£200.75 ? £1,136.75
Evening-rate: (2,160×£0.35)=£756 + (1,440×£0.12)=£172.80 + (365×£0.60)=£219 ? £1,147.80

What this shows: even with a great off-peak rate, a higher day rate can cancel it out. If off-peak share rose to ~50–55%, Tariff 2 could start to win in this example.

Scenario B: Non-EV household, some evening shifting

Home use: 2,900 kWh/year electricity
Of which off-peak: 20% (dishwasher/laundry after 9pm)
Tariff 1 (single-rate): 26p/kWh, standing charge 55p/day
Tariff 2 (evening/off-peak): 34p/kWh day, 14p/kWh off-peak, standing charge 60p/day

Estimated annual cost (energy + standing):
Single-rate: (2,900×£0.26)=£754 + (365×£0.55)=£200.75 ? £954.75
Evening-rate: (2,320×£0.34)=£788.80 + (580×£0.14)=£81.20 + (365×£0.60)=£219 ? £1,089.00

What this shows: if you only shift a small amount, evening/off-peak tariffs can cost more. They’re usually best when a big load (EV/heat pump/storage heating) runs off-peak.

Quick self-check: Roughly what % of your electricity can you reliably move into the cheap window? If it’s under ~25%, a standard tariff often competes well (but not always). If it’s 40%+, an evening/off-peak plan becomes more likely to stack up—especially if standing charge and day rate are reasonable.

Evening-rate tariff types (UK) — quick comparison

Not every supplier uses the same hours, names or rules. Use this table to understand what you’re likely comparing.

Tariff type	Typical cheap window	Usually requires	Main trade-off to check
Time-of-use (evening/night)	Often late evening ? morning (varies by tariff)	Smart meter (commonly)	Higher day rate and/or higher standing charge
EV smart charging	Cheap slots when charging is scheduled/managed	Smart meter + compatible EV/charger/app (often)	Control/automation rules, peak pricing, and data/app dependence
Economy 7 / multi-rate	Typically ~7 off-peak hours overnight (region/meter dependent)	Economy 7-capable meter & correct registers	Day rate can be materially higher than single-rate
Standard single-rate	No cheap window (one unit rate)	Any meter	No “cheap hours” benefit; simplicity can still win overall

Decision checklist: who it suits

You can reliably run a big load in the cheap window (EV charging, heat pump, immersion heater, laundry).
You have (or can get) a working smart meter for time-of-use tariffs.
You’re happy to schedule appliances or automate via a charger/app.
You’ve checked standing charge and day rate don’t wipe out the off-peak benefit.

Who it often doesn’t suit

Most electricity use happens daytime (home working, electric cooking, electric heating during the day).
You have low overall electricity use—standing charge differences matter more.
You can’t use the cheap window consistently (shift work, noise restrictions, shared meters).
You’re in a fixed deal with exit fees that outweigh any likely benefit.

Tip: If you have solar panels or a battery, check how an evening-rate import tariff affects your export tariff and any battery charging rules. Some households benefit from pairing import and export tariffs—but terms vary.

Costs, exclusions & common pitfalls (UK)

1) Standing charge differences

A tariff with “cheap evenings” can still cost more overall if the standing charge is higher—especially for low users or flats.

2) Day rate can be the real price

If you cook, work from home, or heat with electricity during the day, a higher day rate can outweigh off-peak savings.

3) Smart meter and tariff eligibility

Many time-of-use tariffs require a working smart meter in smart mode. If your meter isn’t communicating, you may not qualify.

4) Payment method and credit checks

Some deals are for Direct Debit (credit) customers. Prepayment options exist but vary by supplier and region.

5) Exit fees on fixed tariffs

If you’re mid-fix, leaving early may cost a fee (often per fuel). Compare that against any estimated benefit.

6) Economy 7 timing isn’t universal

Economy 7 hours can differ by region and meter setup. Don’t assume your cheap hours match a neighbour’s.

FAQs

Are “cheap evening rates” the same as Economy 7?

Not always. Economy 7 is a traditional multi-rate setup (usually ~7 off-peak hours overnight). Many “cheap evening” tariffs are modern time-of-use products with different hours and rules, typically needing a smart meter.

Do I need a smart meter to get cheaper evening electricity?

For most time-of-use deals, yes—a working smart meter is commonly required. If you already have a multi-rate meter (e.g., Economy 7), you may be able to access certain multi-rate tariffs without a smart meter, depending on supplier and meter configuration.

Will I definitely save money with an evening/off-peak tariff?

No. Savings depend on how much electricity you use in the cheap window versus the day/peak windows, plus standing charge and any higher day rate. Use a whole-bill comparison and sanity-check it against your real usage pattern.

What time are the cheap evening rates?

It varies by tariff and supplier. Some have a fixed off-peak window (often late evening to morning). EV smart charging tariffs can assign cheaper slots dynamically when charging. Always check the tariff’s published “rate times” and whether they can change with notice.

If I have a heat pump, are evening rates a good idea?

Sometimes. If your heat pump runs heavily during daytime cold periods, a higher day rate can hurt. If you can pre-heat or run more during off-peak (and your home’s insulation supports it), time-of-use can help. It’s worth comparing using your seasonal usage, not just summer months.

Can tenants switch to an evening-rate tariff?

Usually yes, as long as you pay the energy bills and your tenancy doesn’t include energy as part of rent. If you have a prepayment meter, your options may be more limited. If you want a smart meter, your supplier typically needs access to install it.

What if my smart meter isn’t sending readings?

Some time-of-use tariffs may not be available if your meter can’t reliably record usage by time. You can ask your supplier to troubleshoot (signal, commissioning, in-home display, or meter exchange). Availability varies.

Does a cheap evening import tariff affect solar export payments?

It can. Some suppliers bundle import/export products or offer export only if you meet certain conditions (like having a smart meter). If you export solar, check export unit rates, eligibility, and whether you need to switch both import and export together.

How we assess “cheap evening rates”

For this page, we consider an evening-rate option “competitive” when it can reduce estimated annual cost for a household that genuinely uses a meaningful share of electricity in off-peak/evening hours.

Inputs that change results: postcode region, meter type (single vs multi-rate vs smart), payment method (Direct Debit vs prepay), and consumption pattern by time.
What we compare: standing charges, all unit rates (day/off-peak/peak), and any tariff restrictions (app control, smart charging requirements, eligibility rules).
Limitations: suppliers can change prices, withdraw tariffs, or adjust time windows with notice; your real usage split by time can differ from estimates.
