Check if free weekday electricity tariffs are available for your home
“Free weekday electricity” tariffs (sometimes marketed as free power in a set weekday window) can reduce your bills if you can shift usage—for example running the washing machine, tumble dryer, dishwasher, or charging an EV during the free period. The catch is that these deals often come with different rates outside the free window, and the rules can vary by supplier.
Use the form to get a tailored comparison for your postcode and usage. We’ll show you eligible tariffs, highlight key terms, and help you switch to a suitable domestic energy deal.
Tip: If you have (or are getting) a smart meter or EV, these tariffs can be easier to benefit from. If you don’t, availability may be more limited depending on supplier requirements.

Why choose a free weekday electricity tariff?
These tariffs can work well for certain households, but they’re not a universal win. The key is whether you can reliably use more electricity during the weekday free window and use less outside it.
Lower cost for shiftable usage
If you can run appliances during the free period, you could reduce your paid kWh—especially for laundry and dishwashing.
Potentially strong for EV charging
Some households with daytime charging options (or workplace charging patterns) may benefit, depending on the tariff’s weekday timing and caps.
A structured way to cut waste
A defined “free” window makes it easier to build routines and avoid high-consumption habits at expensive times.
Good fit for at-home weekdays
Home workers, carers, retirees and families with flexible schedules often find weekday windows easier to use than overnight-only deals.
Compare beyond the headline
EnergyPlus shows you the full picture: standing charge, non-free unit rates, contract length and any fees.
Switching is straightforward
In most cases your supply won’t be interrupted. Your new supplier handles the switch and you’ll get a final bill from the old one.
How “free weekday electricity” tariffs work (and what to watch)
A free weekday electricity tariff typically provides a set window on weekdays where the electricity unit rate is discounted to £0.00 per kWh (or close to it). Outside that window, you pay the standard unit rate set by the tariff, plus the standing charge.
1) The free window
Check the exact weekday hours. Some exclude bank holidays or have seasonal variations.
2) The paid rates
Unit rates outside the free period may be higher than a standard tariff. Compare the overall cost, not just “free”.
3) Meter requirements
Many time-based deals require a smart meter for accurate time-of-use billing.
4) Limits & terms
Some tariffs apply caps, fair usage policies, or specific conditions. Always read the tariff information label.
Common variations you might see
Weekday free electricity (fixed hours)
A defined weekday slot where electricity is free, with a single paid rate for the rest of the time.
Time-of-use (TOU) with cheap/peak periods
Not necessarily “free”, but offers lower off-peak rates and higher peak rates. Often paired with smart meters.
What to compare so you don’t overpay
With free weekday electricity deals, the headline can be tempting. The right way to choose is to compare the tariff’s total expected annual cost for your usage pattern and location.
| Tariff feature | Why it matters | What to check |
|---|---|---|
| Free electricity window | Savings depend on shifting consumption into that time. | Exact hours, weekdays only, bank holiday treatment, time zone rules. |
| Unit rate outside the window | Can be higher than standard tariffs, offsetting “free” periods. | Peak/day rate, night rate (if any), and how these apply on weekends. |
| Standing charge | You pay this daily regardless of usage. | Compare electricity (and gas if dual fuel) standing charge by region. |
| Contract length & exit fees | Flexibility matters if prices move or the deal doesn’t suit you. | Any early termination fees and when they apply. |
| Meter type / eligibility | Time-based billing usually needs accurate half-hourly reads. | Smart meter requirement, prepay availability, and any restrictions. |
Practical check: Review when your home uses the most electricity. If your biggest usage is evenings and weekends, a weekday-only free window may not be cost-effective unless you can move those loads.

Eligibility and practical requirements
Eligibility for energy tariffs with free weekday electricity varies by supplier and product design. The points below help you understand what might affect availability and pricing for your home.
Smart meters and half-hourly reads
Many weekday free electricity tariffs rely on time-of-use measurement. A smart meter often makes this possible because reads can be captured by time period. If you’re unsure, we’ll help you check.
Your region and network area
Unit rates and standing charges differ across Great Britain due to regional network costs. That means the same tariff name can price differently in different postcodes.
Payment method
Some deals are only available for certain payment types (e.g. monthly Direct Debit). If you prefer prepayment, options may be more limited.
Home setup and lifestyle
You’ll benefit more if you can run appliances in the weekday free slot safely and conveniently. Timers, smart plugs and modern appliances can help.
Common mistakes when choosing “free electricity” deals
Focusing on the free hours only
If the paid unit rate is higher, you can end up worse off unless you consistently shift enough usage into the free window.
Ignoring standing charges
A higher standing charge can outweigh savings, especially for lower-usage households and smaller flats.
Assuming weekends are included
“Weekday” usually means Monday–Friday. Weekends may be billed at the standard rate (or a different time-of-use structure).
FAQs: energy tariffs with free weekday electricity (UK)
Is the electricity genuinely free?
During the defined weekday window, the unit rate may be set to 0p/kWh (or heavily discounted). You’ll usually still pay a standing charge, and electricity used outside the free window will be charged at the tariff’s standard rates. Always confirm the tariff terms and the Tariff Information Label.
Do I need a smart meter?
Often, yes. Time-of-use and free-hour tariffs usually require a smart meter so the supplier can bill usage by time period. If you don’t have one, we can still check what’s available—some suppliers offer alternatives, but they’re less common.
Will switching affect my supply?
In most cases, no. Your gas and electricity supply stays on during the switch. You’ll receive a final bill from your old supplier and start paying your new supplier from the agreed switch date.
Can I get this type of tariff on prepay?
Sometimes, but availability can be limited. If you’re on a prepayment meter, it’s still worth checking—EnergyPlus will show options where available for your postcode and setup.
Will it help if I don’t use much electricity in the daytime?
Potentially not. If most of your usage happens in the evenings/weekends, a weekday-only free window may not reduce your overall cost. In that case, a competitive fixed tariff or another time-of-use option could be better—comparison is the safest way to decide.
Is this the same as Economy 7?
Not necessarily. Economy 7 is a traditional two-rate setup (day/night). “Free weekday electricity” is a different structure that may offer a zero-rate window and different pricing outside it. The best choice depends on your meter, heating type and when you use electricity.
