Compare Economy 7 vs single-rate tariffs (whole-of-market)

Economy 7 can still be worth it in the UK, but only for the right homes. The night rate can be much cheaper, while the day rate is usually higher. The key question is how much electricity you can reliably shift into the night window.

Use the form to get a tailored comparison across UK suppliers. If Economy 7 doesn’t stack up for your usage pattern, we’ll help you spot strong single-rate alternatives too.

What we’ll use to judge if Economy 7 is worth it

  • Your current meter (Economy 7 / smart / standard) and tariff type
  • Where you live (rates vary by region and network area)

What is an Economy 7 tariff?

Economy 7 is a two-rate electricity tariff that charges one price for daytime electricity and a cheaper price for electricity used overnight for a set number of hours (usually 7 hours). It’s designed for homes that can use a large chunk of electricity at night.

It’s most commonly linked with storage heaters and immersion heaters, which can charge/heat water overnight and release heat through the day.

Economy 7 in one sentence

You pay less per kWh at night but typically more per kWh in the day compared with a standard single-rate tariff.

Why people are asking “is it still worth it?”

  • Price differences change: the gap between day and night rates can widen or shrink by supplier and region.
  • More smart tariffs: some households can access time-of-use options that better match their routine than a fixed 7-hour window.
  • Home tech is different: heat pumps, EV chargers and smart home timers can shift usage, but only if the tariff timings fit.
  • Lifestyle shifts: working from home often increases daytime usage, which can reduce Economy 7 savings.

When is Economy 7 worth it in the UK?

Economy 7 is usually worth considering if you can consistently use a significant portion of your electricity during the cheaper night hours. As a rule of thumb, many households start to benefit when around 35–45% or more of electricity use happens overnight — but the true breakeven depends on the exact rates you’re offered.

Good fit

  • Storage heaters set up to charge overnight
  • Immersion heater scheduled for night hours
  • EV charging mostly overnight
  • Dishwasher / washing / tumble dryer often run at night

Maybe

  • Smart meter but unsure of your day/night split
  • Heat pump with a hot water cylinder (can sometimes pre-heat overnight)
  • Shift work or night-time home occupancy
  • High electricity use overall, but flexible timing

Often not worth it

  • Most usage is daytime (WFH, electric cooking, gaming, daytime laundry)
  • Gas central heating and low overnight electricity use
  • No timer controls for major loads
  • You regularly miss the night window

Tip: If you have a smart meter, your supplier may show a breakdown by time of day in your app or online account. That’s the quickest way to check how close you are to the Economy 7 breakeven point.

Quick check: does Economy 7 suit your household?

Use these questions to sense-check whether you’re likely to save. If you answer “yes” to most, it’s worth running a whole-of-market comparison.

  1. Do you have (or can you get) a two-rate meter?
    Economy 7 needs a meter that records day and night usage separately.
  2. Can you use at least ~35–45% of electricity overnight?
    Storage heaters, immersion heaters and EV charging can push you into the right range.
  3. Can your biggest loads be scheduled reliably?
    Timers, smart plugs and appliance delay-start features help avoid accidentally paying daytime rates.
  4. Are you comfortable with slightly higher daytime unit rates?
    If you’re home all day, the higher day rate can outweigh night savings.

Economy 7 rates, night hours and what to look for

Economy 7 always has two unit rates (p/kWh): day and night. The night period is usually 7 hours, but the exact start and end time depends on your meter and region. Some meters switch at different times in summer/winter.

What to compare (beyond the headline)

Tariff detail Why it matters
Day unit rate A higher day rate can wipe out night savings if you’re home during the day.
Night unit rate The bigger the discount vs day rate, the easier it is to benefit.
Standing charge A higher standing charge can reduce savings, especially for low users.
Night hours If the window doesn’t match your routine (or your meter changes with BST/GMT), you may pay the day rate by mistake.
Exit fees / fixed term If you switch and it doesn’t work out, fees can make it costly to change again.

Typical night-time windows (guide)

Night hours vary. These are common examples only — always confirm your exact switching times with your supplier/meter display.

Pattern Example (illustrative)
Single 7-hour block 00:00–07:00 or 23:00–06:00
Split blocks E.g. 00:30–02:30 and 04:30–09:30
BST/GMT change Times may shift by an hour when clocks change

Practical check: Look at your meter display late evening and again after midnight to see when it switches between Rate 1 / Rate 2 (labels differ by meter).

Common Economy 7 mistakes that cost households money

1) Not knowing your night hours

Running appliances at 22:30 thinking it’s “night rate” can mean you pay the higher day rate. Confirm your switching time on the meter or with the supplier.

2) Using more electricity in the day

If your routine changes (e.g. working from home), the higher day rate may outweigh night savings. Re-check your usage split periodically.

3) Storage heaters set incorrectly

Storage heaters can be economical when charged overnight and used efficiently. Incorrect input/output settings can lead to costly top-up heating during the day.

Avoid a surprise bill

  • Use delay-start settings so appliances run fully inside the night window.
  • Schedule hot water heating (immersion) overnight where possible.
  • If you’ve switched to single-rate, check whether your meter setup needs updating.

Economy 7 vs single-rate: what’s better for most UK homes?

For many households without storage heaters, a single-rate tariff can be simpler and sometimes cheaper overall — especially if most electricity is used during the day. But if you can reliably move major loads overnight, Economy 7 may still reduce costs.

The best approach is to compare like-for-like using your estimated usage and timings, rather than relying on averages.

If you… Often consider…
Have storage heaters / immersion Economy 7 (or another time-of-use option)
Work from home most days Single-rate, unless you can shift big loads overnight
Run an EV charger overnight Economy 7 or a smart EV-focused tariff
Can’t control when you use electricity Single-rate (simplicity reduces the risk of paying higher day rates)
Compare both options Read Economy 7 FAQs

Regional considerations across the UK

Economy 7 prices can vary by region because electricity network costs differ across the country. You may see different day/night rates (and standing charges) in London vs the Midlands, Scotland, Wales or the South West.

Postcode matters

We use your postcode to pull the correct regional rates, so you compare like-for-like.

Supplier availability differs

Not every supplier offers every tariff in every region, especially for specific meter setups.

Meter timings can vary

Economy 7 switching times are not universal. Confirm your meter’s schedule before changing habits.

Economy 7 FAQs (UK)

Is Economy 7 cheaper than normal electricity?

It can be, but only if you use enough electricity during the night rate. The day rate is usually higher than a single-rate tariff, so households with mostly daytime use may pay more overall.

How do I know if I’m on an Economy 7 meter?

Your bill may show two electricity unit rates (often labelled Day/Night or Rate 1/Rate 2). Many meters have two registers. If you’re unsure, we can help you identify it during the comparison.

Can I switch from Economy 7 to a single-rate tariff?

Often yes, but it depends on your meter and supplier processes. Sometimes a meter reconfiguration or exchange is required. Always check potential fees and lead times before switching.

Do Economy 7 times change when the clocks change?

Some meters do, some don’t. That’s why it’s important to verify your exact night window (especially around BST/GMT changes) to avoid using electricity at the wrong rate.

Is Economy 7 only for storage heaters?

No, but storage heaters are one of the most common reasons it works well. EV charging, hot water heating and scheduled appliances can also make it worthwhile.

What if I’m not sure how much I use at night?

Start with your meter type and lifestyle. If you have a smart meter, you can often view hourly usage in your supplier app. Otherwise, we’ll help estimate your split as part of the comparison.
