A quick checklist to understand Economy 7
- Check whether you have an Economy 7-compatible meter by contacting your supplier.
- Review how much electricity you use overnight.
- Compare total annual cost, not just the off-peak nighttime rate.
- Consider EV tariffs if you charge an EV at home.
- Check standing charges as well.
Economy 7 is an electricity tariff designed for households that can shift a meaningful share of their energy use to off-peak hours, usually overnight. It works through a dual-rate structure. You pay one price for electricity used during the day and a lower price for electricity used during a seven-hour off-peak window at night. At Fuse Energy, the off-peak window for our off-peak tariffs is between 12am and 7:30am.
This can work well for households with storage heaters, immersion heaters, or EVs, where significant usage can be moved into cheaper periods. However, the peak rate is usually higher than on a standard single-rate tariff, so the value of Economy 7 depends entirely on how well your usage matches the tariff.
Understanding peak and off-peak rates
With Economy 7, your electricity bill is split between off-peak and peak usage. The off-peak rate is designed to be cheaper, while the peak rate is usually more expensive than a standard tariff. The exact off-peak hours can vary by supplier and region, so it is important to confirm the specific timings for your property before switching.
Do you need a special meter?
Yes. To access Economy 7, you need a meter that can record peak and off-peak consumption separately on two distinct registers. This could be a traditional multi-register meter or a smart meter configured for dual-rate tariffs. If you're unsure if your meter is compatible with Economy 7 tariffs, contact your energy supplier who will be able to advise you.
Comparing Economy 7 tariffs is essential because the overall cost depends on more than just the cheap overnight rate. Many households focus on the night unit rate and overlook the day rate or standing charge, which can lead to a poor comparison. The right Economy 7 tariff can lower your bills if you use enough electricity overnight. The wrong one can increase your costs if too much of your usage remains in the daytime period. That is why an effective energy comparison needs to consider your actual usage pattern rather than just the headline price.
Common mistakes to avoid
A common mistake is assuming that Economy 7 is automatically cheaper. In reality, it only tends to work well when a significant portion of your electricity use happens overnight. Another issue is switching without confirming meter compatibility. Without the correct setup, you cannot be billed properly on a dual-rate tariff. It is also easy to rely too heavily on estimated usage. If your actual pattern differs from what a comparison site assumes, the savings may not materialise in practice.
What to look for in an Economy 7 comparison
The most useful comparison looks at the day unit rate, the night unit rate, and the standing charge together. A tariff with a very low night rate may still be poor value if the day rate is high and most of your usage happens outside the off-peak window. In the same way, a reasonable standing charge can make a noticeable difference over the full year.

Is Economy 7 worth it?
Economy 7 can be worth it if you use enough electricity overnight or can shift your usage to off-peak times accordingly. It is often most effective for homes with storage heaters, immersion heaters, or electric vehicles. If most of your usage happens during the day, it may not be the cheapest option.
Do I need a special meter for Economy 7?
Yes. You need a meter that can separately record day and night usage. This is usually a dual-rate meter or a compatible smart meter.
