What is an Economy 10 tariff?
Economy 10 (often shortened to E10) is a UK electricity tariff designed for homes that can use more power at off-peak times — typically properties with electric heating or hot water systems that can charge overnight or in scheduled daytime off-peak windows.
10 off-peak hours
You get ~10 hours of cheaper electricity per day, usually split across night-time and one or two daytime blocks (varies by region and meter setup).
Two (or more) unit rates
Most Economy 10 tariffs have a peak unit rate and an off-peak unit rate. Some meters may record multiple registers.
Not always widely available
Economy 10 tariffs can be more limited than standard single-rate deals, and compatibility depends on your meter and supplier support.
Economy 10 vs Economy 7: Economy 7 offers 7 off-peak hours (usually overnight). Economy 10 offers more off-peak time, often including daytime, which can better suit storage heaters, immersion heaters and some heat pump schedules.
So, what is the cheapest UK Economy 10 tariff this month?
Because Economy 10 pricing is regional and availability depends on your meter, the cheapest deal this month is best defined as: the lowest total estimated cost for your household (standing charge + peak units + off-peak units) among Economy 10-compatible tariffs available in your postcode.
Why there isn’t one national ‘cheapest’ E10
- Regional pricing: standing charges and unit rates vary by distribution region.
- Meter type: some E10 meters have specific switching restrictions.
- Usage split: the more you can move into off-peak, the more competitive E10 can be.
- Tariff structure: some deals have attractive off-peak rates but higher peak rates.
The fastest way to find your cheapest deal
- Enter your postcode (to match regional rates).
- Confirm you’re looking for a home Economy 10 tariff.
- Tell us roughly how you use electricity (especially heating/hot water).
- We shortlist compatible tariffs and show a total cost estimate.
If you only use a small amount of electricity off-peak, a standard single-rate tariff might work out cheaper overall — even if the off-peak price on Economy 10 looks low. That’s why we compare by total cost, not headline unit rates.
Eligibility: who can get an Economy 10 tariff?
Economy 10 is most common in homes with electric heating. Whether you can switch to (or remain on) Economy 10 depends on your meter type and local arrangements.
Typical good fit
- Storage heaters
- Immersion heater hot water tank
- Electric underfloor heating
- Some heat pump schedules
Meter types you may have
- Traditional multi-rate meter (multiple registers)
- Two-meter setup (less common)
- Smart meter configured for multi-rate (where supported)
When it can be harder
- Restricted/legacy meters needing specialist support
- Limited supplier support in your region
- Property has low off-peak usage
Not sure what meter you have? Look at your electricity bill for terms like ‘Day/Night’, ‘Peak/Off-peak’, multiple readings, or an ‘Eco 10’ label. We can help you interpret it during your comparison.
What to compare on Economy 10 (so you don’t overpay)
To find the cheapest Economy 10 tariff for your home, compare the full picture — not just the off-peak unit rate.
| What to check | Why it matters | Quick rule of thumb |
|---|---|---|
| Standing charge | A higher standing charge can cancel out cheaper unit rates. | Compare monthly/annual total cost, not rate-by-rate. |
| Peak unit rate | If you use lots of electricity at peak times, E10 can become expensive. | If most usage is daytime/early evening, check single-rate too. |
| Off-peak unit rate | This drives savings for heating/hot water charging periods. | The more you can shift (heating/hot water/laundry), the better. |
| Off-peak times | Economy 10 hours vary; wrong timing reduces benefit. | Ask your supplier/meter documentation for exact windows. |
| Meter compatibility | Some tariffs won’t support your multi-rate meter setup. | Only compare tariffs confirmed as compatible for your meter type. |
About “this month”: supplier pricing can move during the month. The most accurate way to find the cheapest Economy 10 tariff is to compare available rates in real time for your postcode and meter — exactly what our form is designed for.
How to tell if Economy 10 will actually be cheaper for you
Economy 10 tends to suit homes that can consistently use a meaningful chunk of electricity during off-peak periods. Here’s how to sanity-check value before you switch.
A practical checklist
- Check if heating/hot water can run off-peak (timers, storage, schedules).
- Estimate your off-peak share (even a rough % helps).
- Compare against a single-rate tariff using total cost estimates.
- Confirm the off-peak time windows match your household routine.
- Verify your meter can stay multi-rate after switching.
Common mistakes that increase bills
- Choosing the lowest off-peak rate without checking the peak rate.
- Assuming Economy 10 hours are the same everywhere (they’re not).
- Switching suppliers without confirming meter compatibility first.
- Not using timers for immersion heaters or storage heating.
- Comparing by unit rates only (not standing charge + usage).
If you want, complete the comparison form and we’ll guide you through the options that are actually available for your meter and postcode.
Regional considerations (why your postcode matters)
In the UK, electricity standing charges and unit rates can differ across distribution regions. That means two households with identical usage — but different postcodes — can see different ‘cheapest’ Economy 10 tariffs this month.
Standing charge differences
Even small daily changes add up over a month, especially for lower-usage homes.
Off-peak windows vary
Your Economy 10 schedule can be influenced by local arrangements and meter configuration.
Supplier availability
Some suppliers support fewer Economy 10 setups, so deal availability can differ by region.
Bottom line: postcode-first comparison is the most reliable way to find the cheapest Economy 10 tariff this month for your home.
Economy 10 FAQs
Is Economy 10 cheaper than standard electricity?
It can be, but only if you use enough electricity during off-peak hours. If most of your usage is during peak times, a single-rate tariff may cost less overall.
What times are Economy 10 off-peak?
Off-peak periods vary by region and meter setup. Many schedules include overnight plus one or two daytime blocks. Your bill, meter manual, or supplier can confirm exact windows.
Can I get Economy 10 with a smart meter?
Sometimes. It depends on whether your smart meter and supplier support multi-rate configurations for Economy 10. We’ll focus your results on compatible options.
Do all suppliers offer Economy 10?
No. Economy 10 availability can be limited compared with single-rate deals. That’s why a whole-of-market comparison is helpful — it highlights what’s actually available for your setup.
Will switching affect my heating and hot water circuits?
It can if you have complex or restricted setups. Before switching, confirm how your meter controls off-peak supply to storage heaters or immersion circuits so your heating schedule still works as expected.
How often do Economy 10 prices change?
Suppliers can update prices, withdraw tariffs, or change availability at short notice. The most accurate answer for “this month” comes from checking live options for your postcode and meter type.
