Compare free weekend electricity tariffs against the whole market

“Free weekend electricity” sounds simple, but your savings depend on what happens the rest of the week: higher unit rates on weekdays, different standing charges, and eligibility rules (such as smart meter requirements or specific payment methods).

EnergyPlus is a UK home energy comparison service. Tell us your details and we’ll show you suitable tariffs across the market, including time-of-use and “free” weekend-style deals where available.

What you’ll need (takes about 2 minutes)

  • Your postcode (to check regional pricing and availability)
  • How you pay and your meter type (smart or standard)
  • Approximate usage, or your current supplier info

Tip: If you can move 30%+ of your electricity use into weekends (laundry, dishwasher, batch cooking, EV charging, hot water schedules), weekend-free deals may be worth a closer look. If most of your use is Mon–Fri daytime, they often aren’t.

Important: “Free weekend electricity” usually applies to electricity unit rates in specific time windows. Your standing charge still applies, and weekday unit rates can be higher.

When free weekend electricity tariffs are worth it (UK homes)

These deals can work well in the right household, but they’re not automatically cheaper. The question is: can you reliably move enough kWh into the free period to offset higher weekday prices?

You use lots of electricity at weekends

If your busiest energy days are Saturday/Sunday (big family home, lots of cooking, laundry, devices), free weekend unit rates may reduce your bill.

You can shift demand (without inconvenience)

Dishwasher, washing machine, tumble dryer and batch cooking are easy to move. Savings improve if you’re not forced to use costly weekday peak times.

You can automate usage

Timers, smart plugs, EV chargers and heat pump controls can help you reliably take advantage of the free window each week.

Your weekday rate isn’t significantly higher

Some “free” deals add a premium to weekday unit rates. If that premium is small, your break-even point becomes much easier to hit.

You’re a higher electricity user

The more kWh you can shift to weekends, the more impactful “free” kWh becomes. Low users may see minimal benefit.

You’ve compared properly

The only fair test is to compare the estimated annual cost against fixed, tracker, and other time-of-use tariffs based on your household’s pattern.

How “free weekend electricity” tariffs actually work

In the UK, these tariffs usually provide 0p (or heavily discounted) unit rates for electricity during defined weekend hours. Outside those hours, you pay a standard (often higher) unit rate plus a standing charge.

1) Check the free window

It might be all weekend, specific hours, or a “free period” that resets weekly. Always read the time band.

2) Understand weekday pricing

Weekday unit rates can be higher than a comparable fixed tariff. This is where many households lose savings.

3) Factor in standing charge

Standing charges apply every day regardless of “free” periods, and they vary by region.

4) Track real usage

Smart meter data can show whether you’re genuinely moving kWh into the weekend window over time.

Plain English: You’re swapping some weekday cost for weekend discount. It’s only “free” if the weekend savings outweigh any weekday premium and any differences in standing charge.

Quick savings check: are you likely to benefit?

Use this simple check before you switch. You don’t need perfect numbers—just a realistic view of your routine.

Step 1: Estimate your weekend shift potential

  • Easy to shift: washing, drying, dishwasher, ironing, vacuuming, batch cooking, hobby tools
  • Depends on your home: immersion heater schedules, heat pump hot water, EV charging
  • Hard to shift: weekday showers/cooking, home working equipment, medical devices

If you can only move one or two loads of laundry, savings may be small. If you can move multiple high-kWh activities, the deal can be meaningful.

Step 2: Sanity-check the maths

Ask: “How much higher is the weekday unit rate compared with a normal tariff?”

Rule of thumb: If weekday rates are meaningfully higher, you typically need to shift a larger share of usage (often 25–40%) into the free weekend window to break even.

Compare tariff types: what to check before choosing “free weekends”

Different tariff structures suit different lifestyles. Use the table below to understand what you’re comparing a free weekend electricity tariff against.

Tariff type Best for Watch-outs What to compare
Free weekend electricity Homes that can shift a big chunk of kWh into weekend windows Higher weekday unit rates; eligibility; “free” time bands vary Weekday unit rate vs your alternative; standing charge; free window rules
Fixed tariff Budgeting and predictable costs Exit fees may apply; might miss price falls Unit rates, standing charges, term length, exit fees
Tracker tariff Households comfortable with price movement Rates can rise; rules differ by supplier Tracking method, caps/limits, exit terms
Time-of-use (peak/off-peak) Smart meter homes that can avoid peak hours Peak rates can be expensive; requires behaviour change Peak times, off-peak rates, your usage profile

If you’re comparing deals, ask for the estimated annual cost based on your usage. It’s more useful than focusing on one “free” feature.

Eligibility and meter types (what UK households should know)

Smart meters and time bands

Many weekend-free and time-of-use tariffs rely on a smart meter to measure usage by time period. If you don’t have one, availability may be limited, or you may need to arrange installation.

If you already have a smart meter, check it’s communicating correctly—accurate time-of-use billing needs reliable readings.

Payment methods and switching

Some tariffs are only available with certain payment methods (such as Direct Debit) or online account management. Switching is usually straightforward, but always review any exit fees on your current plan.

If you’re in a prepayment arrangement, options may be different. We’ll show what’s available for your postcode.

Regional note: Electricity standing charges and unit rates vary across Great Britain by distribution region. That’s why postcode-based comparisons are essential.

Common mistakes with free weekend electricity tariffs

Assuming “free” means cheaper overall

If weekday unit rates are significantly higher, you can pay more across the week even with free weekends.

Not checking the actual time window

Some deals aren’t “all weekend”. A short free band may not match your lifestyle (or your appliance cycles).

Forgetting standing charges

Standing charges can make a big difference, especially for low users. Always compare the total estimated annual cost.

Underestimating weekday usage

Home working, school routines and evening cooking often drive Mon–Fri consumption more than people expect.

Changing behaviour for small gains

If savings are marginal, it may not be worth planning your week around a tariff. Choose a plan that fits your life.

Comparing the wrong numbers

Don’t compare only the free rate. Compare weekday unit rates, standing charges, exit fees and the estimated annual cost.

FAQs: free weekend electricity tariffs in the UK

Is weekend electricity really free?

Usually it means the electricity unit rate is 0p (or discounted) during a defined weekend period. You still pay the standing charge, and you’ll pay normal (often higher) unit rates outside the free window.

Always confirm the exact time band and any caps or fair use policies in the tariff terms.

Do I need a smart meter for a free weekend tariff?

Often, yes. Because billing needs to track usage by time period, many suppliers require a smart meter. If you don’t have one, you may have fewer options, or you may need installation before the tariff can apply.

What appliances make the biggest difference at weekends?

High-consumption appliances used in batches can help: tumble dryers, washing machines, dishwashers, electric ovens, immersion heating, and EV charging. The best results come from activities you’ll do anyway—just timed to the free window.

Are free weekend tariffs good for electric vehicles (EVs)?

They can be, if you mainly charge at home and can schedule most charging for weekend free hours. However, compare against EV-focused off-peak night tariffs too—some households charge more during weekday nights than weekends.

Can I save money if I’m out most weekends?

Often not. If you’re rarely at home on weekends, you may not use enough free kWh to make up for higher weekday unit rates. A straightforward fixed tariff may work better.

How do I compare deals fairly?

Compare the estimated annual cost using your usage pattern, and review:

  • Weekday unit rates (and any peak periods)
  • Standing charges (region-specific)
  • The exact free weekend time window
  • Contract length and any exit fees
