What is Economy 10 and how does it work?

Economy 10 is a multi-rate electricity tariff designed to provide ten hours of cheaper electricity each day. Unlike standard tariffs that charge a flat rate regardless of the time of day, Economy 10 divides the 24-hour cycle into peak and off-peak periods. During the ten off-peak hours, the unit rate for electricity is significantly lower, encouraging households to shift high-energy activities to these specific windows.

The multi-rate tariff structure

The core principle of Economy 10 is its multi-rate structure. This means you pay different prices for electricity depending on when you use it. The ten off-peak hours are usually broken down into three separate blocks throughout the day and night. The remaining 14 hours are charged at a higher, peak rate. To benefit from this tariff, you need a compatible multi-rate meter, such as a smart meter or a traditional multi-register meter, which can record consumption during different time bands.

How off-peak pricing benefits the grid

Off-peak pricing structures like Economy 10 encourage consumers to use electricity when overall demand on the National Grid is lower. This helps to balance the grid, reducing strain during peak demand times and making the electricity network more efficient. By spreading out electricity consumption, it can also help to integrate more renewable energy sources, which often generate electricity intermittently.

Understanding Economy 10 off-peak hours

The specific off-peak times for Economy 10 tariffs are not universal. They can vary significantly depending on your energy supplier and even your geographical region within the UK. This variability is a key factor to consider when evaluating if Economy 10 is right for your household.

Typical Economy 10 time slots

While exact times vary, Economy 10 tariffs commonly offer three distinct off-peak periods. A typical example might include a few hours in the afternoon, a longer block overnight, and a short period in the morning. For instance, you might find cheaper rates between 1pm and 4pm, then again from 8pm to 10pm, and finally from 1am to 6am. These examples are illustrative; your actual times will differ.

Why off-peak times vary by supplier and region

Energy suppliers set their Economy 10 time slots based on various factors, including regional network capacity, local demand patterns, and their own wholesale energy purchasing strategies. This means that an Economy 10 tariff from one supplier might have completely different off-peak hours than an Economy 10 tariff from another, even if you live in the same area. It is also possible for the same supplier to offer different Economy 10 schedules in different parts of the country. Some suppliers may also change their off-peak hours when the clocks go back or forward.

How to find your specific Economy 10 schedule

The most reliable way to confirm your Economy 10 off-peak hours is to contact your current energy supplier directly. They will be able to provide you with the exact timings that apply to your tariff and meter. This information is crucial for planning your energy usage effectively and ensuring you benefit from the cheaper rates. You can usually find this information on your bill or by logging into your online account.

Economy 10 vs Economy 7: key differences

Economy 10 and Economy 7 are both multi-rate tariffs, but they differ significantly in the number of cheaper hours they offer and how those hours are distributed. Confusing the two can lead to unexpected energy bills.

Number of off-peak hours compared

The primary difference is in the name: Economy 10 provides ten hours of cheaper electricity, while Economy 7 offers seven hours. This additional three hours of off-peak electricity with Economy 10 can be a significant advantage for households that can shift more of their consumption away from peak times.

Peak and off-peak period distribution

Economy 7 typically offers its seven off-peak hours in a single block overnight, usually between 11pm and 8am (though this can vary). Economy 10, conversely, splits its ten off-peak hours into three distinct periods across the day and night. This distribution can make Economy 10 more flexible for households that might not be able to utilise a single overnight block effectively but can benefit from cheaper rates during an afternoon or early evening slot.

Suitability for different lifestyles

Economy 7 is often best suited for households with significant overnight electricity use, such as those with storage heaters or electric vehicles that can charge exclusively during the night. Economy 10, with its more spread-out off-peak periods, can be a better fit for households that can shift some daytime or early evening usage, in addition to overnight consumption. For example, if you work from home and can run appliances in the afternoon, or if you have an electric vehicle that can charge during a late evening slot, Economy 10 might offer more flexibility.

Pros and cons of an Economy 10 tariff

Economy 10 tariffs offer both opportunities and challenges for households. Understanding these can help you decide if this tariff structure aligns with your energy consumption habits.

Potential for significant savings

The main advantage of an Economy 10 tariff is the potential for significant savings on your electricity bills. By consciously shifting a substantial portion of your energy use to the ten cheaper off-peak hours, you can reduce your overall cost per unit of electricity. This is particularly beneficial for high-energy activities like running washing machines, tumble dryers, dishwashers, or charging electric vehicles.

Requires active energy management

To truly benefit from Economy 10, active energy management is essential. This means being aware of your specific off-peak times and making a conscious effort to use your most energy-intensive appliances during those periods. If you do not adjust your habits, you might find yourself paying higher peak rates for the majority of your consumption, negating any potential savings.

Higher peak rates and standing charges

A key drawback of Economy 10 tariffs is that the peak rate for electricity is typically higher than the flat rate on a standard tariff. Additionally, some multi-rate tariffs may come with slightly higher standing charges. If you struggle to shift enough of your usage to the off-peak windows, the higher peak rates could result in higher overall bills compared to a standard single-rate tariff. It is crucial to assess your ability to adapt your energy consumption patterns before switching.

Is Economy 10 right for your household?

Deciding if an Economy 10 tariff is suitable for you involves a careful assessment of your household's energy consumption patterns and your willingness to adapt.

Assessing your energy consumption patterns

Start by understanding when you use the most electricity. Review your past energy bills or use a smart meter's data to identify your peak usage times. If a significant portion of your electricity consumption already occurs during potential off-peak hours, or if you can easily adjust your routine to do so, Economy 10 could be a good fit. According to Ofgem, the average UK home uses around 2,700 kWh of electricity per year, which equates to roughly 7.5 kWh per day. Knowing your own daily usage helps in this assessment.

Appliances that benefit most from off-peak use

Appliances with high energy consumption are the best candidates for off-peak use. These typically include:

• Washing machines and tumble dryers
• Dishwashers
• Electric vehicle chargers
• Storage heaters
• Immersion heaters for hot water

If you regularly use these appliances, especially if they have timers, you have a strong opportunity to benefit from an Economy 10 tariff.

The role of smart meters in optimisation

Smart meters are invaluable for optimising an Economy 10 tariff. They provide real-time data on your electricity consumption, often broken down by peak and off-peak periods. This visibility allows you to see exactly how much energy you are using and when, helping you to fine-tune your habits and maximise your savings. Dual-rate tariffs, including Economy 10, require either a smart meter or a multi-register (dual-rate) traditional meter to function correctly.

Getting and optimising your Economy 10 tariff

If you have determined that an Economy 10 tariff might be beneficial, there are a few steps to take to get set up and ensure you are making the most of it.

Checking your meter compatibility

Before switching to an Economy 10 tariff, you need to ensure you have a compatible meter. This will typically be a smart meter or a traditional multi-register meter designed to record consumption at different rates. If you have an older meter, such as a Radio Teleswitch Service (RTS) meter, you will need to arrange for it to be replaced. The RTS phase-out began on 30 June 2025, meaning RTS meters will need to be replaced with smart meters by your current supplier.

Switching to an Economy 10 tariff

Once you have confirmed meter compatibility, you can contact energy suppliers to compare their Economy 10 offerings. Look closely at the specific off-peak hours, the unit rates for both peak and off-peak periods, and any standing charges. Compare these against your current usage patterns and estimated shifted usage to calculate potential savings.

Tips for maximising your savings

• Use appliance timers: Set washing machines, dishwashers, and tumble dryers to run during off-peak hours.
• Charge electric vehicles overnight: If you have an EV, schedule charging to coincide with the cheapest rates.
• Pre-heat water: Use immersion heaters during off-peak times to heat water for later use.
• Monitor your usage: Use your smart meter's in-home display or your energy supplier's app to track your consumption and identify areas for further optimisation.

Beyond Economy 10: modern time-of-use tariffs

While Economy 10 has been a traditional option for managing energy costs, the energy landscape is evolving rapidly. Modern time-of-use tariffs, enabled by smart meter technology, offer even greater flexibility and control.

The evolution of dynamic pricing

The energy industry is moving towards more dynamic pricing models. These tariffs can offer even more granular control over pricing, with rates changing not just between peak and off-peak, but sometimes even hourly or half-hourly depending on wholesale market prices and grid conditions. This evolution allows for more precise optimisation of energy use and greater potential savings for those who can adapt.

How smart meters unlock greater control

Smart meters are fundamental to these modern tariffs. They provide the real-time data necessary for dynamic pricing and enable automated processes, such as smart charging for electric vehicles, which can automatically charge when electricity is cheapest. This level of insight and automation empowers households to take unprecedented control over their energy consumption and costs.
