Compare Economy 7 tariffs (whole-of-market) — no smart meter required
If you don’t have a smart meter, you can still switch to Economy 7 as long as your home has (or can get) a two-rate meter and you’re happy to provide day and night readings when asked. We’ll help you compare tariffs that fit your household.
What you’ll need
- Your postcode (to show available suppliers and tariffs)
- Rough usage details or a recent bill (helpful, not essential)
- Your meter type (we’ll explain how to check below)
What is Economy 7?
Economy 7 is a UK electricity tariff with two unit rates: a cheaper night rate for around 7 hours, and a higher day rate for the rest of the time. The exact off-peak times vary by region and meter setup, but they typically fall overnight.
Two readings, two prices
Your bill separates consumption into day and night units. A compatible meter is essential — otherwise suppliers can’t bill two rates accurately.
Works best with overnight use
Storage heaters, immersion heaters and EV charging can be timed to run mostly during the cheaper window.
Not always cheaper overall
If you don’t shift enough usage to off-peak hours, the higher daytime rate can outweigh the savings.
Switching to Economy 7 without a smart meter: what’s required
A smart meter can make Economy 7 billing simpler, but it isn’t always mandatory. What matters is whether your meter can record two separate registers (day and night). If you have a traditional Economy 7 meter (or can get one installed), many suppliers will let you switch.
If you already have an Economy 7 meter
- You can usually choose an Economy 7 tariff without changing the meter.
- You’ll provide manual meter readings (often two readings) if you don’t have a smart meter.
- Your supplier may ask for photos of the meter to confirm the registers.
If you have a single-rate (standard) meter
- To use Economy 7, you’ll normally need a meter exchange to a two-rate meter.
- Some suppliers prefer installing a smart meter for dual-rate tariffs, but it depends on what they can support in your area.
- There may be a charge for a meter change in some circumstances — always check before agreeing.
How to check if you have an Economy 7 meter (without a smart meter)
Before you switch, confirm your meter type. Most Economy 7 meters show two separate readings (or two labelled registers). Here’s what to look for.
Step 1: Check your bill
If your bill shows two unit rates (for example Day and Night, or Rate 1 and Rate 2), you likely have Economy 7 metering.
Step 2: Look at the meter display
On many meters, a button cycles through readings. You may see labels like R1/R2, Low/Normal, or Day/Night. Take a photo for reference.
Step 3: Confirm the off-peak hours
Off-peak times can differ across the UK and may shift with daylight saving. Ask your supplier for your meter’s off-peak window before you change how you use appliances.
Common meter types and what they mean
Who is Economy 7 best for?
Economy 7 is less about the meter and more about when your household uses electricity. If you can shift a meaningful chunk of usage to the night rate, it can reduce your bills. If you can’t, it can increase costs.
Good fit
- Electric storage heaters
- Immersion heater with timer
- EV charging overnight
- Flexible appliance use (dishwasher/washing machine overnight where safe)
May be a poor fit
- Home occupied all day with high daytime use
- Most heating is gas and electricity use is mainly daytime
- Limited ability to shift usage (e.g. electric cooking, daytime laundry)
Best practice
- Know your off-peak hours
- Use timers/controls to shift load
- Submit accurate day & night readings
- Review your tariff at renewal
Economy 7 rates, costs and common pitfalls
When you move to Economy 7, the key trade-off is cheaper night units versus more expensive day units. Understanding the practical details can prevent surprises on your first bill.
What could affect your costs?
- Day-to-night split: the more you use overnight, the better it tends to work.
- Standing charge: fixed daily cost — compare it as well as unit rates.
- Off-peak timing: if your cheap window doesn’t match your usage, savings may be limited.
- Electric heating controls: storage heaters and immersion heaters need correct timers/settings.
Avoid these common mistakes
- Assuming Economy 7 is always cheaper: it depends on your lifestyle and heating.
- Submitting only one reading: two-rate meters need both day and night reads.
- Using appliances at the wrong time: confirm off-peak hours first.
- Not checking compatibility: some properties have complex setups (e.g. older heating circuits).
Will I be charged to change to an Economy 7 meter?
It depends. Some suppliers may exchange a meter at no upfront cost in certain scenarios, while others may quote for a meter change — particularly if there’s extra work required. If you’re switching supplier, ask whether the new supplier will install a dual-rate meter and whether any charges apply before you agree to switch.
FAQs: Economy 7 without a smart meter
Do I need a smart meter to get an Economy 7 tariff?
Not always. Many suppliers will offer Economy 7 if you have a compatible dual-rate meter. Without a smart meter, you’ll normally provide manual readings for both day and night registers when requested.
Can I switch to Economy 7 if I have a standard (single-rate) meter?
You can switch to an Economy 7 tariff only if your metering supports two rates. With a single-rate meter, you would normally need a meter exchange to a dual-rate meter (or a smart meter configured for dual-rate billing).
How do I submit Economy 7 readings without a smart meter?
You’ll provide two readings (day and night). The labels vary (e.g. R1/R2). Take clear photos, note the readings carefully, and submit both values to your supplier via their app, website, or customer service.
What time does Economy 7 switch to night rate?
It varies by area and meter configuration. Your off-peak hours may not be exactly midnight to 7am. Ask your supplier for your precise times before you change how you run heating, hot water or appliances.
Is Economy 7 the same as off-peak or night tariffs?
Economy 7 is a specific two-rate structure (about 7 off-peak hours). Other time-of-use tariffs exist, and some older setups are Economy 10 or other multi-rate arrangements. Your meter type often determines what tariffs are possible.
Can I switch away from Economy 7 later?
Often yes, but you may need a meter change back to single-rate billing depending on the supplier and meter configuration. Compare options before switching, especially if your heating or lifestyle changes.
