Rising energy costs are pushing many UK households to rethink how and when they use power. Since 1 April 2022, the energy price cap has soared by 54%, meaning what once cost £25 a week may now be closer to £37.50. With prices still sitting high, even small adjustments in usage times can make a noticeable difference. One of the most effective and overlooked solutions? Making smarter use of off-peak electricity. 

This guide explores when off-peak hours typically occur, how to know if your tariff supports them, and the best ways to take advantage of cheaper rates without sacrificing comfort.

Understanding off‑peak electricity use helps cut costs and reduce waste - a smarter, greener way to power your home every day.

 

What Are Off‑Peak Times?

Off‑peak electricity typically applies during the night when demand on the grid is low. Under most time-of-use tariffs like Economy 7 or Economy 10, off‑peak hours can range from 10 pm to 8 am, though exact windows depend on your provider. Economy 7 offers seven cheaper hours, while Economy 10 delivers ten, often split across night, evening, and afternoon periods.

 

Do You Actually Benefit From Off‑Peak Tariffs?

Off‑peak isn't automatically cheaper; your daily habits matter. Providers like CompareTheMarket suggest that you need to use 40% or more of your energy during these cheaper hours, especially with electric storage heaters or to charge EVs, to see a real difference. Without shifting usage, you might end up paying more than a standard tariff.

 

Check If You're Already On An Off‑Peak Tariff

Your electricity bill or meter should list separate day and night rates, or your meter will display two readings. Still unsure? Calling your supplier or asking a local electrician can help optimise your setup. Smart meters now support multi-rate billing seamlessly.

 

Best Practices For Off‑Peak Savings

  • Run big appliances at night, like dishwashers, washing machines, and EV charging, and set timers to start after 10 pm. 
  • Use storage heaters and immersion heaters during off‑peak hours to store heat for daytime use. 
  • Consider a home battery system which charges during off‑peak and discharges during peak for even more savings. 
  • Install a smart meter; it enables precise time-of-use billing and gives real-time consumption feedback. 

 

Additional Ways To Slash Your Energy Bill

Even without time-of-use tariffs, these quick steps can reduce energy waste: 

  • Unplug chargers when not in use; laptops, phones, and gadgets on standby can add up. 
  • Air-drying clothes instead of tumble-drying laundry lines is low effort and high savings. 
  • Disable standby modes on TVs, gaming consoles, kettles, and microwaves. 
  • Lower your heating by one degree and switch to LED bulbs for excellent ROI. 

 

Smart Meters & The Future Of Energy Use

Smart meters aren't just gadgets; and they provide real-time data that helps both consumers and grid operators. Average energy usage drops by 3–5% when smart meter feedback is available. They enable utilities to introduce flexible tariffs that align with renewable supply and demand spikes. With the UK aiming for a decarbonised grid by 2030, shifting demand to off‑peak times will shape the future of electricity pricing.

FAQs

What are off-peak electricity times in the UK?

Off-peak times are usually between 10 pm and 8 am when electricity demand is lower. These hours can vary depending on your energy supplier and whether you're on a time-of-use tariff like Economy 7 or Economy 10.

How do I find out my off-peak electricity hours?

Check your electricity bill or meter. Time-of-use tariffs will show separate day and night rates. Your meter may also display two readings. When in doubt, contact your energy supplier directly for clarification.

Do all UK energy suppliers offer off-peak electricity rates?

No, many suppliers still use flat-rate pricing. To benefit from off-peak usage, you need a time-of-use tariff like Economy 7 or 10. Always confirm with your supplier whether such rates are available to you.

What's the difference between Economy 7 and standard tariffs?

Economy 7 offers seven hours of cheaper electricity overnight, while standard tariffs charge the same rate all day. If you use over 40% of your electricity at night, Economy 7 may be more cost-effective.

Are off-peak electricity times the same across the UK?

No, off-peak hours vary by supplier and region. Although 10 pm to 8 am is typical, it's essential to confirm the exact times with your provider to maximise potential savings.

How do smart meters affect off-peak electricity usage?

Smart meters help monitor electricity usage in real-time, making it easier to track when you're using power. They support time-of-use tariffs and encourage smarter energy habits for better control and savings.
