The Short Answer (Because You’re Busy)
If you don’t want the full chat, here it is: overnight. Specifically, between 10 PM and 7 AM.
That’s when electricity is cheapest on most time-of-use tariffs (like Economy 7 or Economy 10). You know, the ones where your smart meter grumbles at you during the day.
But wait—are you on a standard tariff? Then it doesn’t matter. The price is flat. So, you can run it at 3 PM on a Tuesday and it costs the same as 3 AM on a Sunday. Annoying, isn’t it?
The Full Breakdown (For The Nerds Among Us)
1. Economy 7 & Economy 10: The Night Owls
If you’ve got one of these tariffs, you’re paying less for seven (or ten) hours overnight. That’s your golden window.
Set your machine’s delay start function. Pop it on just before bed. Let it rumble while you dream about winning the lottery.
Just be careful: some machines are noisy. That spin cycle at 2 AM might wake the neighbours. Or your cat. Or your cat’s imaginary friend.
2. Off-Peak Weekends (The Sneaky Hack)
Some energy suppliers offer cheaper rates on weekends. Especially if you’re on a time-of-use tariff with a weekend boost.
Check your provider’s app or website. It’s not common, but it exists. Think of it like finding a fiver in an old coat—unexpected and brilliant.
If you spot a weekend discount, do a load of towels. Then do another. You’ve earned it, you domestic superstar.

3. Standard Tariffs: The Great Equaliser
Here’s the sad truth: if you’re on a standard variable tariff, the price is the same 24/7. No midnight specials. No happy hour for your undies.
But don’t despair. You can still save money by washing less often. Wait until you have a full load. That’s the real trick.
And use a 30°C or 20°C cycle. Modern detergents work miracles at lower temps. Your clothes won’t know the difference, but your bank account will.
What About ‘Peak Times’? Should I Avoid Them?
Yes, if you’re on a time-of-use tariff. Peak times are usually 4 PM to 7 PM on weekdays. That’s when everyone is boiling kettles and charging phones.
Running your machine during peak hours is like ordering caviar at a budget restaurant—expensive and a bit silly.
But if you’re on a standard tariff, peak times don’t matter. The price is the price. No drama.
The ‘Delay Start’ Button: Your New Best Friend
Most modern machines have a delay start button. It looks like a little clock or a timer symbol.
Use it. Set it to start at 10 PM or 11 PM. It’s like sending your laundry to a night shift—it works while you sleep.
Plus, you get that smug feeling when you wake up to clean clothes. “Look at me, I’m so efficient,” you’ll think. And you’ll be right.

What About Solar Panels? (The Eco-Warrior’s Choice)
Got solar panels? Lucky you. The cheapest time is midday to 3 PM when the sun is doing its thing.
Run your machine when your panels are generating free electricity. It’s like a renewable energy hug for your electric bill.
But if it’s cloudy, don’t bother. You’re back to the same old grid power. Sorry, sunshine.
One More Thing: Don’t Be a Hero
I get it. You want to save money. But don’t run your washing machine at 3 AM if it wakes you up. Sleep is priceless.
And don’t let laundry pile up for three weeks just to wait for a weekend off-peak window. That’s how you end up wearing your partner’s socks (again).
Balance is key. Use the delay start when you can, but life happens. If you need to wash your lucky jeans at 6 PM, go for it. The energy fairies won’t arrest you.
The Final Spin (Literally)
So, to boil it all down: overnight is cheapest if you’re on a time-of-use tariff. If not, just wash when it’s convenient and lower the temperature.
And always, always check your energy tariff. It’s boring, I know. But it’s the difference between spending a fiver or a tenner on a single load.
Now, go forth and wash. But maybe do it after 10 PM. Your wallet will thank you. And your cat will judge you either way.
