Overview

Economy 7 tariffs can offer significant savings for specific households, but they aren't suitable for everyone. In this article, we’ll explore how these tariffs work and help you determine if switching could benefit your finances.

What is Economy 7?

Economy 7 is an energy tariff that provides reduced electricity rates during off-peak hours, typically at night. This can be a great option for households that use a significant portion of their electricity during these times, particularly those relying on storage heaters or electric water heating systems.

The off-peak period usually runs from midnight to 7 am, but these times can vary based on your energy supplier. To maximize savings, it's essential to shift most of your energy consumption to these cheaper hours.

How to Determine If Economy 7 is Right for You

To see if Economy 7 is a viable option for your household, you need to analyze your energy usage. If you consume around 40% or more of your electricity at night, it might be worth considering this tariff. Check your energy bills for the breakdown of day and night usage.

For example, if your total energy consumption is 3,900 kWh a year and 1,500 kWh is used during off-peak hours, you're likely to benefit from Economy 7 rates.

Switching to Economy 7

If you've decided that Economy 7 could save you money, switching is relatively straightforward. Most suppliers allow you to switch without changing your meter. However, having a smart meter can simplify tracking and managing your energy usage, allowing for a more seamless transition between tariffs.

With Smart Expense, you can easily log any expenses related to switching your energy tariff, helping you keep track of potential savings or costs associated with the change.

Maximizing Your Savings

To truly benefit from an Economy 7 tariff, you need to adjust your daily routines. Use timers for appliances like washing machines and dishwashers to run during off-peak hours. Charge your devices overnight and ensure that any heating systems are programmed correctly to utilize cheaper electricity.

Smart Expense can help you monitor these changes in your energy expenditure, allowing you to see how well you are maximizing your savings over time.

Potential Pitfalls

While Economy 7 can be advantageous, it’s not suitable for everyone. If you use more electricity during peak hours, you may end up paying more than you would with a standard tariff. It’s crucial to evaluate your energy habits before making the switch.

Additionally, ensure that your meter is functioning correctly, as inaccuracies can lead to overpaying. If you notice discrepancies, contact your supplier promptly.
