Estimates only. Your best tariff depends on region, meter type, payment method, and usage (including standing charges and any off-peak rules).

Fast answer: the “cheapest” tariff for an electric cooker depends on your meter and when you cook

If you cook mostly at typical meal times (roughly 5–8pm), the cheapest option is usually the best-priced single-rate tariff (lowest total annual cost once standing charge is included), because most multi-rate discounts don’t apply during peak evening hours.

Important: Don’t shop by unit rate alone. A tariff can have a low p/kWh but a higher standing charge, which can cost more overall—especially if your cooker is your main electrical load.

Key takeaways

  • Single-rate suits most homes with electric cooking at normal hours.
  • Off-peak tariffs (e.g., Economy 7 / smart time-of-use) only help if you can shift meaningful usage to cheaper hours.
  • Check standing charge, exit fees, payment method, and meter compatibility before switching.
  • “Cheap” for a cooker is really “cheap for your whole home’s electricity use”.

What you should gather before comparing

Your postcode
Tariffs vary by region (network area), so postcode matters.
Meter type
Single-rate, Economy 7/10, smart meter, or prepayment.
Rough annual electricity use (kWh)
If you don’t know it, use a recent bill estimate—then refine later.

Compare tariffs the right way (and why cooker-only comparisons mislead)

An electric cooker is a high-power appliance, but it’s usually used in short bursts. That means the tariff that’s “cheapest for cooking” is the one that’s cheapest for your overall electricity profile—including standing charges and any day/night splits.

What typically drives the best deal

  • Standing charge (p/day): often the biggest reason two “similar” tariffs cost different amounts.
  • Unit rate(s) (p/kWh): single rate vs day/night (Economy 7) vs smart time-of-use windows.
  • Payment method: Direct Debit usually differs from prepayment options.
  • Region: distribution network costs vary across Great Britain.
  • Contract terms: fixed vs variable, exit fees, and price change rules.

Renters/tenants: you can usually switch supplier even if you don’t own the property, but check your tenancy agreement and make sure you’re responsible for the energy bills.

Two realistic cooking scenarios (with numbers)

Scenario A: evening cooking, single-rate often wins

Assumptions (illustrative): 2,900 kWh/year total electricity. Cooker uses ~450 kWh/year, mostly 5–8pm. Compare two tariffs:

  • Tariff 1 (single-rate): 24p/kWh, 55p/day standing charge
  • Tariff 2 (time-of-use): 18p/kWh off-peak, 30p/kWh peak, 60p/day standing charge

If most cooking sits in peak hours, Tariff 2’s cheaper off-peak rate may not help much, while the higher standing charge adds cost every day. The “cheapest cooker unit rate” can still mean a higher annual bill.

Why this matters: cooking is time-specific; your tariff needs to match when you use power.

Scenario B: shiftable load + smart tariff can help

Assumptions (illustrative): 4,200 kWh/year. Household can shift usage overnight (dishwasher, laundry, some batch cooking) and has a compatible smart meter.

  • Single-rate: 25p/kWh, 55p/day
  • Economy 7: 29p/kWh day, 14p/kWh night, 55p/day

If you can move, say, 35–45% of electricity to night rate (including some cooking/prep like slow cooker, bread maker, batch oven use earlier/later), Economy 7 can reduce estimated annual cost. If only ~10–15% moves, it often won’t.

Key check: your current day/night split (from bills or smart app) before switching.

Numbers are illustrative only: rates vary by region and supplier, and can change. Use them to understand the trade-offs, not as a quote.

Quick self-check: what cooker do you have?

  • Electric oven / ceramic hob: standard electricity profile.
  • Induction hob: often more efficient than ceramic (can reduce kWh for the same cooking).
  • Range cooker: can add meaningful annual usage—standing charge still matters.

Efficiency affects how much you use (kWh), not the tariff itself—but it changes what “best value” looks like for you.

Tariff types for electric cooking: what usually works

Most UK households cook at similar times, which is why single-rate is often the simplest “cheap” choice. But there are cases where multi-rate tariffs make sense—particularly if you can shift other electricity use too.

1) Single-rate tariffs

One unit rate all day. Usually best if cooking is mainly evenings and you don’t have big overnight loads.

  • Pros: easy to compare, predictable.
  • Watch: standing charge differences; exit fees on fixed deals.

2) Economy 7 / Economy 10

Two (or more) rates with cheaper off-peak hours. Historically linked to storage heaters, but can work if you can shift usage.

  • Pros: cheap night electricity can reduce costs if you shift enough kWh.
  • Watch: day rate often higher; exact off-peak times vary by region/meter.

3) Smart time-of-use tariffs

Rates vary by time/day and need a working smart meter. Some offer cheap windows but can be pricey at peak times.

  • Pros: can reward flexible households.
  • Watch: you must understand peak pricing; eligibility/region rules can apply.

What about “dual fuel”? If you also have gas, comparing gas + electricity together can still be worth doing—but a “dual fuel discount” is not guaranteed, and many suppliers price each fuel independently. Always compare total cost.

Comparison table: which tariff type is most likely cheapest for your cooker use?

Use this to narrow down what to compare. It’s a guide—your best match still depends on actual prices in your region and your household’s usage split.

Your situation Often best starting point Why What to check before switching
You cook mostly 5–8pm and have no big overnight loads Single-rate (fixed or variable) Peak-heavy use rarely benefits from off-peak discounts Standing charge, exit fees, payment method
You already have Economy 7 and use storage heating / overnight appliances Economy 7 Night rate can materially reduce average cost Your day/night split; off-peak hours; day rate increase
You can batch cook at cheaper times and have a smart meter Smart time-of-use Rewards flexibility, but only if you avoid high peak windows Peak prices, eligibility, how rates change, bill volatility
You’re on prepayment (PAYG) Best-value prepayment tariff you can access Tariff choice is more limited; standing charge still applies Debt on meter, smart PAYG options, top-up method/fees

Decision checklist: who it suits / who it doesn’t

A cheap single-rate tariff suits you if:

  • You cook mainly evenings
  • You want predictable bills
  • You don’t have large overnight electricity use

Off-peak / time-of-use may suit you if:

  • You can shift a meaningful share of kWh
  • You have (or can get) the right meter
  • You’re comfortable managing peak windows

The quickest way to sanity-check “cheapest”

  1. Write down your standing charge (p/day) and unit rate (p/kWh) from a recent bill.
  2. Note your meter type (single-rate vs Economy 7 vs smart).
  3. Compare deals by estimated annual cost for your usage—not by unit rate alone.
  4. Check tariff end date and exit fees if fixing.

Costs, exclusions and common pitfalls (UK-specific)

These are the most common reasons people pick a “cheap” tariff and later find it wasn’t right for their cooking and household use.

1) Standing charge can outweigh small unit-rate wins

If you’re a lower user (or only use electricity heavily for cooking), a higher standing charge can wipe out a lower p/kWh.

Compare the total estimated annual cost. It includes both standing charge and usage.

2) Economy 7 can raise costs if you don’t use enough at night

Many Economy 7 tariffs have a higher day rate. If most cooking is at standard times, you may pay more overall.

Tip: check your bill for separate day/night kWh, or ask your supplier for your split.

3) Smart tariffs may have expensive peak windows

If your household is busiest at peak times (often early evening), a time-of-use tariff can be costlier even if it has very cheap hours elsewhere.

Always read the tariff’s time bands and whether prices can change.

4) Meter compatibility and switching timelines

Some tariffs require a smart meter or a specific multi-rate meter. If you switch tariff type, you may need a meter reconfiguration.

In Great Britain, switching processes and timescales can vary; your supplier should confirm what’s required.

5) Fixes can include exit fees

If you leave a fixed tariff early, you may pay an exit fee per fuel. This matters if you’re planning to move home or switch again soon.

6) Don’t overlook payment method

Direct Debit, cash/cheque, and prepayment tariffs can differ. Make sure the price you compare matches how you pay.

If your cooker is your biggest electrical load: it can still be worth focusing on standing charge + the most common cooking hours. For many homes, that’s a strong indicator of best value.

FAQs: cheapest tariff for electric cooking (UK)

Is there a special “cooker tariff” in the UK?

Not usually. Your cooker uses electricity like any other appliance, so you’re choosing the best electricity tariff for your home’s overall usage (including standing charge and any time bands).

Is Economy 7 cheaper for an electric oven?

Only if you can shift enough electricity into the cheaper night hours. Most oven use is in the evening, which is typically charged at the higher day rate on Economy 7.

Do smart time-of-use tariffs help with cooking costs?

They can, but only if you can avoid expensive peak windows or move other usage (laundry, dishwashing, charging) into cheap periods. If you must cook at peak times, they may cost more overall.

Do electric cookers use a lot of electricity?

They can be high power (kW) while on, but usage is often short. Your annual kWh depends on household size and cooking habits. A range cooker used for long periods can noticeably increase annual electricity use.

Can I switch tariffs if I rent?

In many cases, yes—if you’re the bill payer. If you have a prepayment meter or the landlord pays the bills, your options can be different. If in doubt, check your tenancy agreement and ask your supplier.

Will switching interrupt my electricity supply?

Switching supplier normally doesn’t interrupt supply. Your new supplier should handle the transfer process, though timelines and steps can vary, especially if a meter exchange or reconfiguration is needed.

What if I have a prepayment meter?

You can still compare, but tariff availability may be narrower. If you have debt on the meter, it can affect switching. Consider whether a smart prepayment meter could widen options (depending on eligibility).

What’s the single biggest thing to look for?

The estimated annual cost for your postcode, meter type and usage. It’s the most reliable way to judge “cheapest”, because it accounts for standing charge and any time-of-use rates.

How we assess “cheapest” for electric cooker use

We don’t label one tariff as universally cheapest. Instead, we explain how to identify the lowest estimated annual cost tariff for your household, because:

  • Electricity prices vary by region and payment method.
  • Standing charges can materially change the result.
  • Multi-rate tariffs depend on when you use electricity, not just how much.

Our examples use illustrative rates to show trade-offs. When you request a quote, we compare tariffs available for your postcode and meter type, and we encourage checking:

  • unit rate(s) and standing charge
  • contract length and exit fees
  • any eligibility requirements (e.g., smart meter needed)
  • how/when prices can change (fixed vs variable, time bands)

Limitations and caveats

  • Tariffs and rates can change; always confirm details on the supplier’s tariff information label before switching.
  • Off-peak hours for Economy 7/10 can vary by meter and region; verify times with your supplier.
  • If you’re in Northern Ireland, the market and switching process differs from Great Britain.
  • Some tariffs require a smart meter in credit mode; smart prepayment options vary.
