Why UK households are switching to free weekend electricity

Zero cost for weekend electricity

Pay nothing for the electricity you use at weekends — zero unit rate for Saturday and Sunday (or specific off-peak windows), which can cut hundreds of pounds from your annual bill if you're home at weekends.

No lifestyle changes required

Unlike Economy 7 which requires you to shift usage to the middle of the night, free weekend tariffs let you use electricity normally — cooking, washing, watching TV — just on different days of the week.

Perfect for home workers and families

Households that are home on Saturdays and Sundays — families, home workers, people who batch cook at weekends — benefit most. The savings are proportional to how much electricity you actually use on free days.

Which UK suppliers currently offer free weekend electricity?

The free weekend electricity market is one of the most actively changing areas in UK energy in 2026. Suppliers regularly launch new offers, adjust terms and pause deals based on grid conditions and wholesale prices. Below is the current landscape — always use our live comparison tool for the most up-to-date availability at your postcode.

Octopus Energy

Octopus offers free electricity events through Octopus Power-Ups — targeted free electricity windows for customers on Agile and Intelligent tariffs. These are triggered by surplus renewable energy on the grid and can include weekend slots. Octopus Intelligent also offers guaranteed cheap overnight EV charging rates, which can extend to weekends.

Best for: smart meter households, EV drivers, tech-savvy switchers who want to maximise free periods.

E.ON Next

E.ON Next has previously offered free weekend electricity promotions for new customers switching through comparison sites, typically as a fixed-term bonus on a standard variable or fixed tariff. Availability fluctuates — check the live comparison for current E.ON Next weekend offers.

Best for: households wanting a straightforward tariff switch with weekend savings built in.

EDF Energy

EDF offers weekend and off-peak electricity incentives through their GoElectric range and smart tariff products. These are particularly aimed at EV drivers but available to all households with a compatible smart meter. EDF's weekend rates can be significantly below the standard unit rate.

Best for: EV owners and households wanting a well-established supplier with weekend rate benefits.

OVO Energy

OVO periodically offers weekend energy credits and free-hour bonuses through their OVO Beyond plan, rewarding customers who reduce usage during peak periods. These can include weekend free slots and bonus credits applied to your bill.

Best for: environmentally-conscious households who want rewards for flexible energy use.

Important: Free weekend tariff availability changes frequently. The above reflects the general market as of early 2026 — use the EnergyPlus comparison tool to see which specific free weekend deals are live at your postcode right now.

How free weekend electricity tariffs work

The two types of free weekend tariff

Type How it works
Zero unit rate weekends Electricity used on Saturday and Sunday is billed at 0p/kWh. You pay only the standing charge on those days.
Weekend credits / rebates Weekend usage is billed normally but offset by credits applied to your account — effectively making it free on your monthly bill.

Both approaches deliver the same financial outcome. The difference is cosmetic — your bill layout may look different but the annual saving is equivalent.

What to run at weekends to maximise savings

  1. EV home charging — plug in Saturday morning and charge throughout the weekend for free.
  2. Washing machine and tumble dryer — batch your laundry on weekends instead of weeknights.
  3. Dishwasher — run full loads on Saturday and Sunday rather than daily through the week.
  4. Immersion water heater — if on a timer, set it to heat at weekends to reduce weekday hot water costs.
  5. Home battery charging — if you have a battery storage system, charge it free at weekends and discharge on weeknights.

Do you need a smart meter for free weekend electricity?

Yes — almost all free weekend electricity tariffs require a smart meter, because your supplier needs to measure your usage separately for weekdays and weekends. If you don't have a smart meter, you can request one free of charge from your current supplier. Most installations are completed within 2–4 weeks.

Is a free weekend electricity tariff worth it for you?

A free weekend tariff is likely worth it if…

  • You or your family are regularly at home on Saturdays and Sundays.
  • Weekends account for 30% or more of your total weekly electricity usage.
  • You have an EV you can charge at home over the weekend.
  • You do high-consumption tasks at weekends — laundry, cooking, cleaning.
  • You have a smart meter already installed (or are willing to get one).

A standard tariff may suit you better if…

  • You're rarely home at weekends — at work, travelling or away regularly.
  • Your electricity usage is evenly spread across all seven days of the week.
  • The free weekend tariff's higher weekday unit rate outweighs your weekend savings.
  • You don't have a smart meter and aren't able to get one installed.

Key calculation: Free weekend tariffs often come with slightly higher weekday unit rates. The tariff is only worth switching to if your total weekend savings exceed the extra you'd pay on weekdays. Check your smart meter app for your weekend vs weekday usage split — if weekends account for 30%+ of your usage, the maths almost always works in your favour. Use our free comparison tool to calculate your personalised annual saving right now.

Smart meters and free weekend electricity: what you need to know

A smart meter is the essential requirement for any free weekend electricity tariff. Without one, your supplier cannot measure when at the weekend you're using electricity — and cannot offer you a zero weekend rate. Here's what you need to know about smart meter eligibility and installation.

Getting a smart meter installed

Smart meters are available free of charge from your current energy supplier. Request one through your supplier's app, website or customer service line. Most installations take 1–2 hours and are available at a time convenient to you.

SMETS1 vs SMETS2 meters

Older SMETS1 smart meters sometimes lose smart functionality when you switch supplier. SMETS2 meters (installed since 2018) work across all suppliers. If you switch to a free weekend tariff, confirm your meter type is compatible with your new supplier before switching.

Checking your weekend usage split

Most supplier apps and in-home displays can show your electricity usage broken down by day of the week. Check the last 4 weeks of data to see what percentage of your total usage falls on Saturdays and Sundays — this is the most accurate way to estimate your potential saving.

How to maximise your free weekend electricity savings

Once you're on a free weekend electricity tariff, the goal is simple: shift as much of your high-consumption electricity use as possible to Saturday and Sunday. Here's how to get the most from every free hour available to you.

Shift these tasks to weekends

  • All laundry — washing machine and tumble dryer cycles.
  • Dishwasher — run full loads on Saturday and Sunday.
  • EV charging — plug in Friday night and charge through the weekend.
  • Batch cooking — use your oven, hob or slow cooker for the week ahead.
  • Home battery charging — charge fully on Saturday to discharge on weekday evenings.
  • Vacuuming and high-power cleaning appliances.

Reduce these during the week

  • Avoid running the washing machine or tumble dryer on weekday evenings if possible.
  • Use a timer on your dishwasher to run at weekends rather than after weeknight meals.
  • Charge devices, laptops and tablets at weekends rather than overnight on weekdays.
  • Use a slow cooker or prep meals at the weekend to reduce weekday cooking time and energy use.

How much could you save? A realistic estimate

  1. Check your smart meter app for your average weekend electricity usage in kWh (Saturday + Sunday combined).
  2. Multiply that by your current unit rate in pence per kWh to get your current weekend spend.
  3. On a zero-rate weekend tariff, that figure goes to zero — that's your gross weekly saving.
  4. Multiply by 52 for your annual saving, then subtract any increase in weekday unit rates to get your net annual saving.

At the current UK average unit rate of around 24p/kWh, a household using 10 kWh per weekend day saves roughly £250 per year before accounting for any weekday rate difference. Higher usage households and EV owners can save significantly more.

Common mistakes with free weekend electricity tariffs — and how to avoid them

Only comparing the weekend rate

Free weekend tariffs often carry a higher weekday unit rate than standard deals. Always compare the total projected annual cost — not just the zero-rate weekend headline — before switching. Our comparison tool does this calculation automatically.

Not checking smart meter compatibility

Switching to a free weekend tariff with an incompatible SMETS1 meter can mean losing smart functionality entirely, leaving you unable to access time-of-use rates. Confirm meter compatibility with your new supplier before completing any switch.

Forgetting to actually shift usage

The savings only materialise if you actively move high-consumption tasks to the weekend. Households who switch but don't change their habits often find the benefit is marginal. Set reminders and use appliance timers to lock in the habit.

Thinking of switching away from a free weekend tariff?

If your weekday usage has increased — due to home working, a new appliance or a change in routine — it's worth re-running the comparison to check whether you'd still save overall. Use the comparison form and we'll show you the full picture.

Free weekend electricity FAQs

What counts as "weekend" on a free weekend electricity tariff?

This varies by supplier and tariff. Most define the weekend as the full 48-hour period from midnight Friday night through to midnight Sunday night. Some tariffs define a narrower window — for example, Saturday and Sunday daytime only. Always check the specific tariff terms before switching.

Are free weekend electricity tariffs available on prepayment meters?

Some suppliers offer free weekend rates on smart prepayment meters, but availability is more limited than for credit meter customers. If you're on a prepayment meter, use our comparison tool to see which free weekend deals are currently available to you.

Can I get free weekend electricity with a dual fuel tariff?

Free weekend rates typically apply to electricity only — gas is billed at standard rates regardless of the day. Some dual fuel tariffs include a free weekend electricity component alongside a standard gas rate. We'll show the full tariff breakdown, including gas costs, in your comparison results.

Will I still pay a standing charge at weekends?

Yes — the daily standing charge applies every day of the week, including weekends, on all UK energy tariffs. Only the unit rate for electricity consumed goes to zero. The standing charge covers network maintenance costs and is fixed regardless of your usage or the day of the week.

How is free weekend electricity different from Octopus Agile?

Octopus Agile charges a rate that changes every 30 minutes based on wholesale electricity prices — meaning rates can be very low (or even negative) at weekends when renewable generation is high, but are not guaranteed to be free. A dedicated free weekend tariff gives you a guaranteed zero rate on weekends regardless of wholesale market conditions.

Is free weekend electricity the same as Economy 7?

No — they are completely different tariff types. Economy 7 gives you cheaper (but not free) electricity for seven hours overnight, every night of the week. Free weekend tariffs give you zero-rate electricity on Saturdays and Sundays at any time. The right choice depends entirely on when you use the most electricity.
