Check if “free electricity weekends” are available for your home
In the UK, truly “free” electricity at the weekend is uncommon and often marketed under specific smart or time-of-use structures. Some tariffs offer discounted weekend hours (e.g. evenings/weekends), others offer lower rates in set time windows, and a few promotions have limited “free” periods with conditions.
EnergyPlus is a whole-of-market comparison service. We’ll help you compare your current costs with:
- Standard single-rate tariffs (same unit rate all day)
- Economy 7 / multi-rate tariffs (off-peak periods set by your meter/network)
- Smart time-of-use tariffs (rates vary by time/day; weekend offers may appear here)
- Fixed deals for price certainty versus variable flexibility
Important: A tariff advertised as “free weekends” can still cost more overall if weekday unit rates or standing charges are higher. Always compare based on your likely usage pattern, not the headline.

Which UK suppliers offer free electricity weekends?
In today’s UK market, “free electricity weekends” is more often a tariff feature than a permanent supplier promise. Offers can appear, change, or be withdrawn at short notice, and eligibility can depend on your meter type (smart meter or multi-rate), region, and payment method.
What EnergyPlus does: instead of listing a static “top suppliers” list that may be out of date, we check live whole-of-market tariff data for your postcode and highlight any tariffs that include weekend/off-peak incentives.
Time-of-use (smart) tariffs
Some suppliers run smart tariffs with lower rates at certain times, sometimes including weekend windows. These may suit households that can shift usage (washing, EV charging, dishwasher) into those cheaper periods.
Multi-rate (Economy 7 / Economy 10)
Not “free”, but off-peak can land overnight and sometimes differs by region. Good for storage heaters or flexible users, but the day rate can be higher.
Promotional weekend incentives
Occasionally, suppliers trial limited “weekend credit” or discounted blocks. Terms may include caps, specific hours, app participation, or minimum spend.
How “free weekend electricity” tariffs work (and how to spot the catch)
A weekend offer can mean very different things depending on the tariff. Before you switch, it’s worth translating the headline into unit rates, time bands, and standing charges.
Check the exact hours
“Weekend” might mean Saturday–Sunday all day, or just a set window (for example, Saturday and Sunday afternoons/evenings). If the times don’t match your heavy usage, you may not benefit.
Compare weekday rates and standing charges
Some tariffs recover the “free” cost through higher weekday unit prices or a higher standing charge. Always compare annual cost estimates for your usage.
Look for caps, fair-use policies, or credits
Some “free” structures are actually a credit applied up to a limit, or a discounted rate rather than £0.00/kWh. Terms matter.
Confirm meter requirements
Many time-based offers require a smart meter or a compatible multi-rate setup. If you don’t have one, we’ll show alternatives that still cut bills.
Practical tip: If you can move high-load appliances to the weekend (laundry, tumble dryer, batch cooking), a weekend-discount tariff can help. If your usage is spread evenly across the week, a strong fixed single-rate deal may win.
What to check before choosing a free weekend electricity tariff
Use this checklist to avoid switching to a deal that looks good in a headline but costs more over a year.
| What to check | Why it matters | What EnergyPlus highlights |
|---|---|---|
| Weekend time window | Your savings depend on whether your usage lines up with the “free/cheap” hours. | Clear time bands and when they apply (Sat/Sun, evenings, bank holidays if stated). |
| Weekday unit rate | A higher weekday rate can wipe out weekend savings. | Side-by-side estimate versus strong single-rate alternatives. |
| Standing charge | Even if some kWh are £0, you still pay a daily charge. | Standing charge differences and annual impact. |
| Meter & eligibility | Some offers require a smart meter or specific metering setup. | Whether your tariff options depend on smart/multi-rate metering. |
| Exit fees & fix length | A fix can protect price, but exit fees reduce flexibility. | Key terms so you can decide if you want flexibility or certainty. |
| Fair-use caps/credits | Some “free” structures are capped or applied as bill credit. | Where terms suggest limits or conditions, we flag them for review. |
Could free weekend electricity actually save you money?
It depends on how much electricity you can shift into the weekend window. The biggest wins tend to be for homes that can concentrate usage into fewer hours (for example, families doing laundry on weekends or households charging an EV at home). Below are typical patterns to help you decide what to compare.
When weekend offers can work well
- You regularly run high-load appliances at weekends (washing machine, tumble dryer, dishwasher).
- You can batch tasks into a specific time window (e.g. Saturday afternoon).
- You have a smart meter and are comfortable with time-based rates.
- Your weekday daytime usage is relatively low (out at work/school).
When a strong fixed/single-rate tariff may be better
- Your electricity use is evenly spread across the week.
- You can’t reliably use energy during the “free/cheap” hours.
- The tariff has a higher standing charge that erodes benefits.
- You prefer predictable bills with fewer time bands to track.
Reality check: Even if electricity is advertised as “free” on weekends, you’ll still pay a standing charge and you may pay higher rates at other times. Comparing total annual cost is the safest way to judge value.
Eligibility and regional considerations (UK homes)

Free electricity weekends UK: FAQs
Is there really a UK energy tariff with free electricity all weekend?
Genuinely £0 electricity for every kWh across the whole weekend is uncommon. When you see “free weekends”, it often means discounted rates during specific weekend hours, a promotion with conditions, or a benefit that’s balanced by higher rates at other times. Always check the tariff details and compare total annual cost.
Use the comparison form to see what’s available where you live.
Do I need a smart meter for weekend electricity deals?
Often, yes. Many weekend/time-of-use offers rely on smart metering to measure usage by time band. If you don’t have a smart meter, you may still be able to access Economy 7/multi-rate options (depending on your setup) or choose a competitive single-rate tariff.
Will “free weekends” help if I work from home?
It can, but only if your highest electricity usage happens in the discounted weekend window. If your weekday daytime usage is high (heating controls, cooking, computers), a higher weekday unit rate may cancel out the benefit. Comparing your estimated annual cost is key.
Are weekend tariffs good for EV charging?
They can be, depending on the hours and your charger schedule. Some EV-focused tariffs prioritise overnight off-peak rather than weekends. EnergyPlus can help you compare weekend-window options versus overnight off-peak alternatives so you can choose what matches how you charge.
Could I pay more overall with a free weekend tariff?
Yes. The most common pitfalls are higher weekday unit rates, higher standing charges, and discounted hours that don’t match your routine. That’s why we recommend comparing the total annual estimate (and reviewing key terms) rather than choosing based on “free” messaging.
How often do these tariffs change in the UK?
Availability and pricing can change frequently. Suppliers can launch or withdraw promotions quickly, and rates vary by region. Checking live options for your postcode is the most reliable approach.
