Check the best Sunday free electricity-style tariffs for your home
Some UK suppliers offer time-of-use (TOU) tariffs that include a zero or heavily discounted unit rate on Sundays (often during set hours). These deals can be ideal if you can shift energy-heavy tasks—washing, tumble drying, batch cooking, EV charging—into the free window.
EnergyPlus compares whole-of-market home energy tariffs, including TOU options where available. We’ll help you understand the full cost (including standing charge, peak/off-peak rates, and any eligibility rules) so you can choose confidently.
Good to know before you compare
- “Free” usually means unit rate only during set Sunday hours; you still pay the standing charge.
- Most TOU tariffs require a smart meter (or you’ll need one installed).
- It’s not always best-value if weekday peak rates are higher—always compare the total estimated annual cost.

Why choose a tariff with free electricity on Sundays?
If your household can move a portion of usage to Sundays, a free-Sunday electricity tariff (or similar Sunday discounted rate) can reduce your average unit cost. The key is understanding when the free window applies and whether any weekday peak rates offset the benefit.
Make Sundays your low-cost day
Run energy-heavy appliances during the free period—washing machine, dishwasher, tumble dryer, immersion heater (if suitable), and batch cooking.
Potentially ideal for EV drivers
If the tariff includes a Sunday zero-rate window, it can complement overnight off-peak charging—especially for households that do longer journeys at weekends.
Transparent, measurable savings
With a smart meter, you can see exactly how much energy you used during the free window and whether the tariff is working for you.
No need to change weekdays
Even if your weekdays are busy, concentrating big jobs on a Sunday can still deliver value—provided peak rates aren’t excessive.
Better use of renewable generation
Some TOU products are designed to encourage demand when the grid is greener or less strained, which can align with lower costs.
Compare properly (not just the headline)
EnergyPlus highlights standing charges, all time bands, contract length and exit fees so you can compare apples with apples.
How “free electricity on Sundays” tariffs work in the UK
In the UK, “free Sunday electricity” is typically offered as part of a smart time-of-use tariff. You’ll see different rates depending on the day/time. The supplier may set the Sunday unit rate to 0p/kWh (or a very low rate) for a specific window.
- Check eligibility: These tariffs usually require a smart meter. Some suppliers limit availability by region or meter configuration.
- Understand the time bands: You may have peak rates (higher), off-peak rates (lower), and the Sunday free window.
- Shift flexible usage: To benefit, move discretionary loads into Sunday (and/or off-peak) while keeping an eye on weekday peak usage.
- Compare total cost: The right choice depends on your annual kWh, lifestyle, and standing charge—headline “free” doesn’t always win overall.
Important clarification
“Free electricity Sundays” does not usually mean your entire bill is free on Sundays. In most cases, the unit rate for electricity during set Sunday hours is free/discounted, but your standing charge still applies and gas (if applicable) is billed separately.
What to check before switching to a free Sunday tariff
To find the best UK energy tariff with free electricity Sundays for your home, look beyond the headline. Use this checklist to avoid surprises and improve your chances of real savings.
If you want a personalised view of Sunday tariff availability and whether you’d likely save, use the comparison form and we’ll match options to your home details.
Savings examples: when free Sundays can (and can’t) help
Real savings depend on how much electricity you can shift into the free window and what you pay at other times. Here are simple examples to illustrate the principle (figures are illustrative; your rates and usage will differ).
Example A: family home shifting laundry to Sunday
- Shifted usage into Sunday window: 12 kWh/week (laundry + dishwasher + batch cooking)
- Typical unit rate you’d otherwise pay: 28p/kWh
- Potential weekly saving: £3.36
- Potential annual saving: ~£175
But: check weekday peak rates and standing charge—those can reduce net savings.
Example B: low-usage flat (may not suit)
- Shifted usage into Sunday window: 3 kWh/week
- Potential annual saving at 28p/kWh: ~£44
- If the tariff’s standing charge is higher by 15p/day: extra annual cost ~£55
Outcome: could be worse overall. A standard fixed or competitive variable tariff may win.
A quick way to estimate if it’s worth it
Add up the appliances you can realistically run in the Sunday free window (kWh). Multiply by the unit rate you’d otherwise pay. Then subtract any extra standing charge or higher weekday peak costs. If you’re unsure, submit the form and we’ll help you compare on total cost.
Regional considerations across the UK
Your available electricity tariffs (including Sunday free electricity offers) can vary by postcode because network costs differ by region. That’s why comparing with your postcode is essential.
England
Standing charges and unit rates differ by electricity distribution region. A strong Sunday deal in one area may not be best elsewhere.
Scotland
Some TOU tariffs are available, but pricing and availability can vary more by region—especially where network costs are higher.
Wales
You may see different standing charges compared with nearby English regions. Always check total annual cost, not just the Sunday headline.
Northern Ireland uses a different retail market structure from Great Britain. If you’re in NI, availability may differ—use your postcode and we’ll advise the appropriate route.
FAQs: free electricity Sundays & UK time-of-use tariffs
Do I need a smart meter for a free Sunday tariff?
Usually, yes. Sunday free electricity-style tariffs are typically smart time-of-use products that rely on half-hourly readings. If you don’t have a smart meter, the supplier may arrange installation.
Is the whole day Sunday free?
Not always. Many tariffs offer a free or discounted time window on Sunday. The window and rules differ by supplier—always confirm the hours and any caps/conditions.
Will I still pay a standing charge?
Yes in most cases. The standing charge is separate from the unit rate. When we compare, we include the standing charge so you can judge the true cost.
Can I get free Sundays on gas too?
These offers are usually for electricity. Gas is commonly priced as a single unit rate plus standing charge, though suppliers may offer separate incentives.
Are free Sunday tariffs good for heat pumps?
They can be, but only if the tariff’s peak rates don’t outweigh the benefit and your heating pattern allows some flexibility. For many heat pump homes, a tariff with strong off-peak rates (not just Sundays) may be more suitable.
How quickly can I switch?
Switching is typically straightforward and doesn’t interrupt your supply. The exact timing depends on supplier processes and any cooling-off periods.
