Energy tariffs with free evening electricity in the UK (2026)

Compare free evening electricity tariffs (UK homes)

Free evening electricity tariffs reward households that can shift usage into a set evening window — for example charging an EV, running appliances, or heating water later in the day. The key is understanding what counts as “free” (it’s usually the unit rate for electricity during the window) and what still applies (a standing charge and a higher peak rate at other times).

EnergyPlus is a whole-of-market comparison service for UK home energy. We help you find evening and off-peak style tariffs where available and compare them against standard fixed and variable deals — all benchmarked against the current Ofgem cap — so you can choose what’s actually cheapest for your household pattern.

What you’ll need to compare

• Postcode (to show regional rates & supplier availability)
• Contact details (so we can send results and help you switch)
• If you know it: your current tariff, typical monthly bill, and whether you have a smart meter

Lower-cost evenings for high usage

If you can run the dishwasher, washing machine, tumble dryer, immersion heater, or EV charging during the free window, you may slash the cost of your heaviest electricity hours.

Clearer behaviour-based savings

Unlike broad “cheap energy” claims, these tariffs create a simple target: shift usage into specific hours. That makes potential savings easier to estimate against the cap.

Useful for smart home & EV schedules

Smart meters, EV chargers and appliance timers automate the shift. If you already schedule loads, a free-evening window slots into your routine.

Works well alongside daytime solar

Some households use solar during the day and push discretionary consumption into the evening free window, reducing grid imports across the day.

Options beyond “free evenings”

If a true free-evening offer isn’t available in your area, we can still compare evening-heavy time-of-use tariffs and off-peak rates that may be cheaper overall.

Whole-of-market checks

EnergyPlus compares across the market so you can see whether the “free” window outweighs peak pricing versus a fixed deal at the cap.

Do I need a smart meter?

Usually, yes. Most free-evening and other time-of-use tariffs rely on half-hourly smart meter readings. If you don’t currently have a smart meter, many suppliers can install one free of charge — but eligibility and appointment times vary.

If you have a smart meter but it isn’t sending readings reliably, we’ll advise whether the tariff is still suitable.

What if I’m on Economy 7 or Economy 10?

Some households have multi-rate meters (commonly used for storage heating). Switching to a free-evening style tariff may involve meter considerations, and not every supplier supports every configuration.

We’ll help you compare like-for-like options and avoid switching you onto a tariff that doesn’t fit your meter setup.

EV owners

If your charging schedule can reliably run during the evening window, the “free” unit rate can have a meaningful impact — EV charging is often the single biggest saving.

Families with predictable routines

Laundry, cooking, showers and cleaning can be planned around the same time daily or weekly.

Smart home users

Appliance timers, smart plugs, battery storage and EV chargers can automate shifting usage into the cheap window.

Use appliance delay timers

Most washing machines, dishwashers and tumble dryers have a delay-start function. Set them to run inside the free window so the heaviest cycles cost you nothing per unit.

Schedule EV charging

Set your car or charger to charge only during the free hours. A single overnight or evening charge is often the largest, most controllable load in the home.

Heat water in the window

If you have an immersion heater or hot-water cylinder, use its timer to heat during the free period and store the hot water for later use.

Charge a home battery

A home battery can soak up free-window electricity and discharge it during peak hours, smoothing out the higher rates you’d otherwise pay outside the window.

Batch your high-power tasks

Group cooking, ironing, vacuuming and similar high-draw jobs into the window where practical, rather than spreading them across peak hours.

Check your first bills

Review your first one or two statements to confirm the free period is being applied and that your shifted usage is landing inside the window.

A simple way to sense-check savings

1. Estimate how many kWh you can shift into the evening window each week (EV charging, appliances, immersion, etc.).
2. Multiply those kWh by the rate you’d otherwise pay (the cap is 26.11p/kWh) to approximate the “value” of the free window.
3. Compare that value with any increase in peak unit rate and standing charge on the new tariff.

If you can’t shift much usage: a tariff marketed as “free” may cost more overall than a competitively priced fixed tariff at or below the cap.

What we compare for you

• Peak vs off-peak/free window unit rates
• Standing charges by region
• Tariff type (fixed/variable), contract length and exit fees
• Supplier availability for your postcode
• Meter requirements (including smart meter considerations)
• How each deal compares to the current Ofgem cap

Assuming “free” means the whole bill is cheaper

A free-evening tariff can come with a peak unit rate above the cap. The best deal depends on your usage across the entire day — not just the free window.

Not checking the exact time window

“Evening” may not match your routine. If your main loads happen before or after the window, savings shrink quickly.

Overlooking standing charges

Standing charges vary by region and can be a bigger factor than people expect — especially for low-usage households.

Switching without meter compatibility checks

Some tariffs need a smart meter or specific configuration. If your meter can’t support the readings, billing can become complicated.
