British Gas Economy 10 tariff rates and times
Economy 10 (E10) gives you 10 cheaper hours of electricity, but the exact times — and whether it’s worth it — depend on your meter and tariff. This page explains how E10 usually works in the UK, what to check on a British Gas account, and how to compare options safely without guesswork.
- Answer-first: what British Gas Economy 10 times typically look like and why they vary
- What to look for on your bill/meter so you don’t switch onto the wrong rates
- Two real-world examples (with assumptions) to help you sanity-check your own costs
You’ll see live availability and prices after you enter your postcode. Economy 10 isn’t offered everywhere and time bands can differ by meter and region.
Fast answer
British Gas Economy 10 tariff rates and times vary by meter setup and local electricity network, but Economy 10 usually gives you 10 off-peak hours split across day, evening and overnight rather than one continuous night block. Your meter/bill will show the exact registers and time bands for your home, so check that before comparing.
What you can rely on
E10 is a two-rate electricity setup: you’ll have a peak (day) rate and an off-peak rate. The off-peak hours are fixed by your meter’s timing and the network rules in your area, not by guesswork.
What often trips people up
Two homes can both be “Economy 10” but have different time bands. On some meters the times drift when the clocks change, and some bills label the registers in confusing ways (Rate 1/Rate 2 instead of “day/night”).
Best next step
Use your postcode to view live tariffs and then sanity-check against your heating/hot water pattern. If most of your electric heating runs outside the off-peak hours, E10 can cost more than a single-rate tariff.
We can’t publish British Gas’s live Economy 10 unit rates, standing charges, or guaranteed time bands here because they change and depend on your meter and region. Use the quote journey for current figures for your postcode.
Economy 10 times: what “10 hours off-peak” usually means
Economy 10 is designed for homes that use lots of electricity for heating and hot water, often with storage heaters or a hot water cylinder. Instead of one overnight off-peak block (like Economy 7), Economy 10 commonly splits cheaper electricity into several blocks across the day.
The exact schedule is not universal. It can differ by:
- Your meter type and configuration
- Some E10 meters have two registers; others have more complex setups. Smart meters can present registers differently again.
- Your local electricity network (region)
- Time bands are often set in line with regional network arrangements, so two UK areas can run different E10 windows.
- Clock changes and meter time drift
- Some meters don’t automatically adjust for British Summer Time. That can make the “cheap hours” feel like they’ve shifted by an hour (annoying, but common).
How to find your actual off-peak times (the practical way)
1) Look at your bill or online account. You’re hunting for a clue like “Rate 1/Rate 2”, “Day/Night”, “Peak/Off-peak”, or an Economy 10 label. Some suppliers show the times; others don’t.
If the times aren’t shown, note the register names and how many rates you’re billed on. That alone helps prevent switching mistakes.
2) Check the meter registers at known times. Pick a daytime hour and a late-night hour. If the “off-peak” register is ticking up in the afternoon or evening, you likely have split time bands (a typical Economy 10 pattern).
Write down the readings with timestamps; it’s surprisingly useful when you’re comparing tariffs.
3) Confirm what your heating is wired to. In some homes, storage heaters or immersion heaters are on a dedicated circuit that’s only live during off-peak windows (or controlled by a time switch). In others, everything runs on the same supply and timing matters more.
If you’re unsure, a qualified electrician can tell you quickly.
If you’re on electric storage heating and your home is set up around off-peak power, avoid switching tariffs based only on a headline “10 cheap hours”. The time bands are the whole point.
Compare Economy 10 options safely (without accidental rate changes)
If you’re specifically looking at British Gas Economy 10, the key is to compare what you have now with what you’d be moved onto — and to confirm your meter setup is supported. Economy 10 tariffs aren’t offered universally, and some suppliers handle legacy E10 meter arrangements differently.
Before you request a switch or a quote, grab three things (two minutes, tops):
- Your postcode (tariffs are priced by region).
- How many rates you’re billed on (one, two, or more).
- A rough off-peak usage share (even a guess: 30%, 50%, 70%).
If you don’t know your off-peak share, don’t stress. The examples below show how a small change in off-peak usage can swing the outcome.

Two quick checks that prevent most Economy 10 mistakes
Check A: Do you have an Economy 10 meter, or just an “off-peak” meter?
People sometimes call any multi-rate setup “Economy 10”. Your bill might show two rates but still be Economy 7, or a different regional arrangement. If you’re unsure, take a photo of the meter display (not decorative; just for your records) and note the register labels.
Check B: Are your storage heaters and hot water actually using off-peak?
If your immersion heater is set to come on at 6pm, Economy 10 won’t magically make that cheap unless that hour is in your off-peak window. Timer settings matter just as much as the tariff.
Economy 10 vs Economy 7 vs single-rate: what changes
These tariff types can all be “fine” — the best one is usually the one that matches when your home uses electricity. Here’s a plain comparison to help you decide what to investigate next.
| Tariff type | Cheaper hours | Typical fit | Common watch-outs |
|---|---|---|---|
| Economy 10 | 10 hours, often split across day/evening/night (varies by meter/region) | Electric heating homes that can shift demand into the off-peak windows | Time bands can differ; billing labels can be confusing; not always widely available |
| Economy 7 | 7 hours, usually overnight (exact start/end varies) | Storage heaters and hot water charging overnight | If you’re awake and using power in the evening, you may pay more at peak rates |
| Single-rate | None (same unit rate all day) | Most homes without storage heating, or anyone who can’t shift usage reliably | You won’t benefit from cheap windows; may be less suitable for storage-heater setups |
Decision checklist (quick and honest)
Economy 10 may suit you if:
- you’ve got storage heaters and/or an immersion heater you can time to off-peak windows
- you can use some electricity in daytime off-peak blocks (common with E10)
- your household routine is fairly regular (so you can actually hit the cheaper hours)
Economy 10 is often a poor fit if:
- your main electricity use is evenings (cooking, showers, tumble dryer) outside the off-peak bands
- you don’t have electric heating, and you’re on E10 “by history” rather than choice
- you can’t control when hot water heating runs
Costs, exclusions and common Economy 10 pitfalls
1) Off-peak hours aren’t “10 hours straight”
Many E10 setups split hours into multiple blocks. That can be brilliant for top-up heat, but it also means you need to know the pattern to benefit. Don’t assume your cheap rate starts at midnight.
2) Register labels can be misleading
“Rate 1” isn’t always day. “Rate 2” isn’t always night. On some meters, the cheaper register is Rate 2; on others it’s Rate 1. If you submit meter readings, send them against the right register names as shown on the bill.
3) Not all suppliers support every E10 setup
Some Economy 10 arrangements are older and can be awkward to bill on certain systems. That doesn’t mean you’re stuck, but it does mean you should confirm the meter type before you switch.
Standing charges and unit rates: Economy 10 doesn’t automatically mean “cheaper overall”. Two-rate tariffs can have higher peak unit rates, and standing charges vary by supplier, region and payment method. Use live quotes for your postcode.
Clock changes: If your cheap hours feel off by an hour around March/October, your meter may not change with BST. You can still use the tariff — you just need to run heating/hot water to the meter’s clock, not your phone’s.
Two realistic scenarios (with numbers you can swap for yours)
Because we can’t publish live British Gas rates here, the examples below use illustrative maths to show how Economy 10 behaves. Replace the rates with the ones you see in your quote results or bill to get a more accurate view.
Scenario A: storage-heated flat that hits off-peak well
Assumptions (example only): 4,500 kWh/year electricity. Off-peak share 65% because storage heaters and immersion heater are timed to off-peak windows. Illustrative rates: off-peak 18p/kWh, peak 35p/kWh. Standing charge ignored to keep the example focused on timing.
| Off-peak usage | 2,925 kWh × £0.18 = £526.50 |
| Peak usage | 1,575 kWh × £0.35 = £551.25 |
| Estimated unit-cost total | £1,077.75 |
Why it works: most kWh are in the cheaper register. If your off-peak share is genuinely high, a two-rate tariff can be competitive even if the peak rate is punchy.
Scenario B: same home, but habits move usage into peak
Assumptions (example only): still 4,500 kWh/year, but off-peak share drops to 35% (more evening heating, more tumble dryer use, immersion not well timed). Same illustrative rates: off-peak 18p/kWh, peak 35p/kWh. Standing charge ignored.
| Off-peak usage | 1,575 kWh × £0.18 = £283.50 |
| Peak usage | 2,925 kWh × £0.35 = £1,023.75 |
| Estimated unit-cost total | £1,307.25 |
Same home, same kWh — but the split changes the outcome. If your off-peak share is low, a single-rate tariff can be easier and sometimes cheaper once standing charges are included.
A quick way to estimate your off-peak share: take two recent bills (or smart readings), note how many kWh were charged on each register, and divide off-peak kWh by total kWh. If the bill doesn’t label off-peak clearly, use the register names shown on the bill and match them to your meter display.
FAQs
What are British Gas Economy 10 times?
British Gas Economy 10 times depend on your meter and region, but Economy 10 usually means 10 off-peak hours split across the day, evening and overnight rather than a single night-only block. Your bill and meter registers are the safest way to confirm the exact time bands for your home.
Why do Economy 10 times vary by area?
Economy 10 time bands are linked to regional electricity network arrangements and meter configurations. That’s why one postcode can have different off-peak windows to another, even if both are labelled “Economy 10”. Your meter’s timing (and whether it adjusts for BST) can also affect what you experience.
How can I tell if I’m on Economy 10 or Economy 7?
Start with your bill: it should show whether you’re billed on one rate or multiple rates, and may mention Economy 7 or Economy 10. If it just shows “Rate 1” and “Rate 2”, check when each register advances by taking readings at a few times across the day and late at night. Split daytime off-peak points more towards E10.
Can I switch away from an Economy 10 meter?
Often yes, but it depends on your meter setup and what tariffs are available for it. If your heating/hot water relies on off-peak circuits, switching to a single-rate tariff without changing wiring or controls can increase costs. Always confirm how your heaters and immersion are connected before making changes.
Does a smart meter change Economy 10 times?
A smart meter doesn’t automatically change your off-peak time bands, but it can change how they’re displayed and billed (for example, how the registers appear on statements). If you move to a different tariff type, the supplier may need to reconfigure how your meter records peak and off-peak usage.
Is Economy 10 cheaper than a normal tariff?
It can be, but only if a good chunk of your electricity use happens in the off-peak windows. If most of your usage lands on the peak rate (often evenings), Economy 10 can work out more expensive than single-rate once you account for both unit rates and standing charges. Use live quotes and your own usage split to check.
What should I do if my Economy 10 meter readings look wrong?
First, confirm you’re reading the correct registers (as named on your bill) and that you’re not mixing day and off-peak. If the numbers are jumping unexpectedly or the display is unclear, contact your supplier to check the meter configuration. Citizens Advice has guidance on what to do if you think your meter or bills are wrong.
Do Economy 10 times change at weekends?
In many setups the off-peak schedule is the same every day, but you can’t assume that for every meter configuration. The only reliable answer is what your meter and tariff documentation specify for your property. If you’re trying to plan appliance use, validate by watching which register advances at different times on a weekday and at the weekend.
Trust, methodology and sources
How we assess Economy 10 guidance on this page
We wrote this to help you avoid the most common Economy 10 problems: assuming the wrong time bands, mis-reading registers, and comparing tariffs without considering when your heating and hot water actually run.
Our approach:
We treat Economy 10 times as meter-specific. Where this guide says “usually” or “commonly”, it’s describing UK-wide patterns without claiming your exact hours.
We don’t publish or guess British Gas unit rates, standing charges, or tariff names. Live prices and availability are shown after you enter your postcode in the quote journey.
We use illustrative scenarios with clearly stated assumptions to show how the peak/off-peak split changes total cost. They’re not promises or personalised projections.
Limitations (so you know what this page can’t do)
Economy 10 is one of those areas where small technical details matter. Without your meter configuration, your region, and your actual usage pattern, no responsible site can tell you your exact times or costs. Use this page to know what to check, then confirm through your supplier documentation and live quotes.
