Fast answer: EDF Economy 7 tariff rates and night times
EDF Economy 7 tariff rates and night times usually mean two electricity unit rates (a cheaper night rate for about 7 hours and a higher day rate) with the off‑peak window set by your meter’s configuration, not by a universal UK timetable. Your exact EDF rates and night times can vary by region, meter type and tariff.
Key takeaway 1
“Night times” aren’t always midnight–7am. They can shift (and may be split into two blocks) depending on your meter and local setup.
Key takeaway 2
Economy 7 tends to work best if you can reliably use a meaningful share of electricity overnight (e.g. storage heating, immersion heater, EV charging).
Key takeaway 3
The only safe way to know whether EDF Economy 7 is good value for you is to compare using your usage pattern and postcode — not headline “night rate” claims.
Quick check: If you don’t have storage heaters/immersion/EV and most of your electricity is used during the day/evening, Economy 7 can cost more than a single-rate tariff because the day unit rate is often higher.
How Economy 7 works (and what “EDF Economy 7” means)
Economy 7 is a two-rate electricity pricing structure. You’re billed for electricity at a day (peak) unit rate for most of the day and a night (off‑peak) unit rate for around 7 hours overnight. You’ll also pay a daily standing charge.
When people say “EDF Economy 7”, they usually mean they’re with EDF and on an Economy 7‑style tariff. However, the exact rates and the exact off‑peak hours depend on your tariff, meter configuration and where you live. Suppliers can offer multiple tariffs that use Economy 7 metering, and those tariffs can change over time.
What can change EDF Economy 7 rates?
- Region (electricity distribution area) — costs vary across Great Britain.
- Payment method — e.g. direct debit vs prepayment can differ.
- Meter type — traditional Economy 7 meters vs smart meters configured for two rates.
- Tariff type — fixed, variable and other structures can price day/night differently.

How to check your Economy 7 night times (step by step)
The safest way to confirm your off‑peak window is to check your meter and your tariff information. “Night” hours can differ between households even within the same supplier.
- Look at your latest bill or online account for two electricity unit rates (often labelled “Day” and “Night”, “Peak” and “Off‑peak”, or Rate 1 / Rate 2).
- Identify which register is day vs night. Some meters label registers in a way that isn’t intuitive (e.g. “Rate 1” might be night on one setup and day on another).
- Check your meter’s clock if it’s an older Economy 7 meter. The meter’s displayed time can drift, meaning the “night” switch may not align perfectly with real time.
- Do a simple observation test: note the reading on both registers shortly before a suspected changeover time, then check again shortly after to see which register advanced.
- If you have a smart meter, ask your supplier (or check your in‑home display/app) which hours are configured as off‑peak for your tariff.
Caveat: Some Economy 7 configurations use a split off‑peak window (for example, a few hours late evening and the rest early morning). Don’t assume it’s always a single 7‑hour block.
What to do if your night times don’t match what you expected
- Don’t change your routine based on assumptions. Confirm the switching times first (especially if you rely on timers).
- If your meter clock is wrong, contact your supplier. A drifting clock can shift the cheaper hours.
- If you’re on the wrong tariff for your lifestyle, compare alternatives (single-rate or other time-of-use options) using your postcode.
Economy 7 vs single-rate: what to compare (not just the night rate)
To decide whether an EDF Economy 7 tariff is right for you, compare the whole bill: both unit rates, the standing charge, and how much electricity you can realistically shift into the off‑peak window.
| What you’re comparing | Economy 7 (two-rate) | Single-rate (one-rate) | Why it matters |
|---|---|---|---|
| Day unit rate | Usually higher than single-rate | One rate all day | If most usage is daytime/evening, higher day rates can outweigh cheaper nights. |
| Night unit rate | Cheaper for ~7 hours | Not applicable | Only valuable if you can use enough electricity during your off-peak window. |
| Standing charge | Applies daily | Applies daily | A low night rate doesn’t help if standing charges (and day rates) are higher overall. |
| Off-peak hours | Set by meter configuration | Not applicable | If your cheap hours don’t align with timers or your lifestyle, you may not benefit. |
| Exit fees / terms | Varies by tariff | Varies by tariff | Check tariff end dates, price changes, and any fees before switching. |
Economy 7 may suit you if…
- You have storage heaters and/or an immersion heater designed to heat overnight.
- You can regularly run big loads overnight (dishwasher, washing machine) using timers safely.
- You charge an EV or home battery primarily during the off‑peak window.
- You can keep a meaningful share of your electricity use at night (many households aim for a substantial portion, but the “right” share depends on rates).
Economy 7 may not suit you if…
- Most of your usage is evenings and weekends (cooking, TV, heating controls, tumble dryer).
- You don’t have anything significant to run overnight (or you’re not comfortable using timers).
- Your property’s heating is mainly gas boiler (or you use little electricity for heating).
- You’re unsure which hours are off‑peak and can’t easily check the register changeover.
Two realistic scenarios (with numbers you can personalise)
These examples show how to think about Economy 7 — they are not EDF quotes. Replace the placeholder rates with the live figures you see when you compare.
Scenario A: Flat with storage heating (Economy 7-friendly)
- Assumptions
- Annual electricity use: 4,200 kWh. Off‑peak share: 55% (storage heating + hot water overnight). Example rates to test: Night 12p/kWh, Day 34p/kWh. Standing charge ignored for simplicity (compare it separately).
- Estimated unit-cost calculation
- Night: 2,310 kWh × 12p = £277.20
Day: 1,890 kWh × 34p = £642.60
Total (units only): £919.80/year
If a single-rate alternative were, for example, 28p/kWh, the same 4,200 kWh would cost £1,176 (units only). In this style of usage pattern, Economy 7 can be competitive — if your real night share stays high.
Scenario B: Family home without storage heating (often not ideal)
- Assumptions
- Annual electricity use: 3,100 kWh. Off‑peak share: 20% (a few appliances on timer). Example rates to test: Night 12p/kWh, Day 34p/kWh. Standing charge ignored for simplicity.
- Estimated unit-cost calculation
- Night: 620 kWh × 12p = £74.40
Day: 2,480 kWh × 34p = £843.20
Total (units only): £917.60/year
With the same single-rate example of 28p/kWh, 3,100 kWh would cost £868 (units only). With low off‑peak usage, the higher day rate can cancel out the cheaper nights.
How to use these scenarios: In your quote results, plug in the actual day/night rates and your best estimate of off‑peak percentage. This gives a quick “sanity check” before you commit to switching.
Costs, exclusions and common pitfalls to avoid
Economy 7 can be a great fit for the right home, but it’s easy to get caught out. These are the issues we see most often when households compare EDF Economy 7 tariff rates and night times.
1) Assuming night times are universal
Off‑peak hours are tied to your meter configuration. Always confirm your exact window before changing appliance timers.
2) Not checking which register is which
Rate 1/Rate 2 labels can be confusing. A quick reading check around changeover can prevent billing misunderstandings.
3) Day rate shock
If you work from home or have high daytime use, the higher day rate can outweigh the night discount.
4) Standing charge and payment method
Comparisons should include standing charge and your payment type (direct debit vs prepayment), as these affect the total.
5) Heating controls set incorrectly
Storage heater/immersion timers should align with off‑peak hours. If not, you may accidentally heat water/rooms at the day rate.
6) Switching and meter compatibility
Some tariff types require specific metering configurations. If you’re unsure, compare first and confirm what your meter supports.
Safety note: If you plan to run appliances overnight, follow manufacturer guidance and avoid running high-risk appliances unattended. Economy savings aren’t worth a safety risk.
FAQs
What are EDF Economy 7 night times?
EDF Economy 7 night times are the off‑peak hours when your electricity is billed at the cheaper “night” unit rate on a two‑rate tariff. The exact hours aren’t universal and are usually set by your meter’s configuration (and sometimes shown on your bill or online account).
How many hours is Economy 7 off-peak?
Economy 7 typically gives around 7 hours of off‑peak pricing per day, but the window can vary by meter setup and can sometimes be split across two time blocks. Always confirm the actual hours for your meter before relying on timers.
Are EDF Economy 7 rates the same everywhere in the UK?
No. EDF Economy 7 rates can vary by region (your electricity distribution area), payment method (such as direct debit or prepayment), meter type and the specific tariff you’re on. Use a postcode-based comparison to see live rates for your home.
How do I know if Rate 1 is night or day on my Economy 7 meter?
Don’t assume. Rate 1 and Rate 2 labels vary by meter configuration. The simplest method is to note both readings shortly before a suspected changeover time and then again shortly after — the register that increases during the off‑peak window is your night register.
Can I switch from Economy 7 to a single-rate tariff?
Often yes, but it depends on your meter type and the tariff you choose. Some households may need their metering configuration changed. Compare tariffs first, then confirm what’s required for your specific setup before you agree to switch.
Does a smart meter change my Economy 7 night times?
A smart meter doesn’t automatically change your off‑peak hours. The night window is defined by your tariff and how the meter is configured for that tariff. If you’re unsure, ask your supplier to confirm the off‑peak times tied to your account.
Is Economy 7 cheaper with an electric vehicle?
It can be, if you can charge most of your EV within your off‑peak window and the day rate/standing charge don’t make the overall tariff more expensive. Compare tariffs using your expected overnight charging to see whether a two‑rate option beats a single-rate alternative for your home.
What should I check before choosing an EDF Economy 7 tariff?
Check the day rate, night rate, standing charge, the exact off‑peak hours, tariff end date, and any fees or terms that apply. Then estimate how much electricity you can realistically shift to off‑peak. A tariff is only “good value” if it fits your usage pattern.

How we assess “Economy 7 rates and night times”
This guide is designed to help you make a decision even when supplier pricing changes. We focus on the parts that are stable and user‑verifiable: what Economy 7 is, what makes night times vary, and what you should compare to avoid bill surprises.
- No live-rate claims: We don’t state EDF’s current Economy 7 unit rates, standing charges, or tariff names because these vary by postcode, meter type and tariff and change frequently.
- Examples use placeholder rates: Scenario calculations use example p/kWh figures only to show the method. Swap in the live day/night rates from your quote results for a personalised view.
- Limitations: Real bills include standing charges, VAT and (for some homes) other costs. Meter timing can drift on older meters. Off‑peak windows may be split depending on configuration.
