Fast answer: what’s usually cheapest after a standing charge cut?

After a standing charge cut, tariffs with low unit rates still matter most for most households — but the balance shifts slightly towards tariffs that don’t “overcharge” on the daily fixed cost. The cheapest option for you depends on your annual kWh usage, your region, meter type (single-rate vs Economy 7 vs smart), and payment method.

Key point: A standing charge cut helps everyone a bit, but it helps low-usage homes most. High-usage homes still win most from a lower unit rate (p/kWh).

If you use less electricity

  • Prioritise lower standing charge (p/day)
  • Be cautious of tariffs advertising a slightly lower unit rate but a much higher standing charge
  • Check if you can reduce costs further with direct debit (often cheapest payment method)

If you use more electricity

  • Prioritise unit rate (p/kWh) and any time-of-use pricing
  • Standing charge matters, but usually less than saving 2–5p/kWh on higher usage
  • Check for exit fees on fixes if you might move or want flexibility

If you have Economy 7 / two-rate

  • Compare day rate, night rate and standing charge together
  • If your night usage is low, Economy 7 can cost more than a single-rate tariff
  • Confirm your meter and tariff type before switching

What to do next: collect your last bill (or app screenshot) and note: (1) unit rate(s), (2) standing charge, (3) annual usage (kWh), and (4) whether you pay by direct debit, cash/cheque, or prepayment.

How to compare tariffs after a standing charge cut (simple method)

  1. Find your annual usage (kWh). Use your last 12 months’ bill if possible. If you don’t have it, use your supplier app or monthly statements. (Avoid comparing tariffs without usage: it can mislead.)
  2. Note your meter type: single-rate, Economy 7/two-rate, or smart time-of-use. Only compare like with like.
  3. Calculate the annual standing charge: standing charge (p/day) × 365 ÷ 100.
  4. Calculate the annual unit cost: unit rate (p/kWh) × annual kWh ÷ 100. (For Economy 7: do this separately for day and night using your split.)
  5. Add them together and include any fixed extras (e.g., add-on services) if you pay for them.
  6. Check the contract terms: exit fees, end date, and whether rates can change (variable) or are fixed.

Why the standing charge cut can change “cheapest”: When the daily fixed cost drops, a tariff that previously looked expensive for low users may become competitive — but only if its unit rate isn’t significantly higher.

Scenario 1: Low usage flat (standing charge matters more)

Assumptions (illustrative): Single-rate meter, Direct Debit, 1,500 kWh/year. Standing charge falls by 10p/day after a cut. Compare Tariff A vs Tariff B.

Item Tariff A Tariff B
Unit rate 26p/kWh 24p/kWh
Standing charge (after cut) 45p/day 60p/day
Estimated annual unit cost 1,500 × 26p = £390 1,500 × 24p = £360
Estimated annual standing charge 365 × 45p = £164.25 365 × 60p = £219.00
Estimated total £554.25 £579.00

Even with a higher unit rate, Tariff A is cheaper here because the standing charge difference is large for a low-usage household. This is exactly the kind of outcome a standing charge cut can make more common.

Scenario 2: High usage home (unit rate matters more)

Assumptions (illustrative): Single-rate meter, Direct Debit, 4,200 kWh/year. Standing charge falls by 10p/day after a cut. Compare Tariff C vs Tariff D.

Item Tariff C Tariff D
Unit rate 26p/kWh 23p/kWh
Standing charge (after cut) 45p/day 65p/day
Estimated annual unit cost 4,200 × 26p = £1,092 4,200 × 23p = £966
Estimated annual standing charge 365 × 45p = £164.25 365 × 65p = £237.25
Estimated total £1,256.25 £1,203.25

Here, Tariff D is cheaper despite the higher standing charge because the lower unit rate dominates at higher usage.

These scenarios are simplified examples to show the trade-off. Real tariffs vary by region (distribution area), VAT is typically included in domestic rates, and some tariffs have different prices by time of day.

Tariff types compared: which tends to be cheapest after a standing charge cut?

There isn’t one universally “cheapest electricity tariff” in the UK. But you can shortlist the right type quickly by matching your usage, risk tolerance and meter setup.

Tariff type What it is Can be cheapest for… Watch-outs
Standard Variable (SVT) Supplier’s default tariff (often price-capped); rates can change. People who want flexibility and no exit fees; those waiting for a better fix. May be beaten by competitive fixed deals; prices can rise/fall with cap changes.
Fixed (12–24 months) Unit rate and standing charge fixed for a term. People who value price certainty; households expecting steady usage. Exit fees may apply; “fixed” doesn’t always mean cheapest overall.
No-exit-fee fix Fixed rates but with more flexible terms. Renters and movers; anyone wanting to switch again if prices improve. Sometimes priced slightly higher than exit-fee fixes.
Economy 7 / two-rate Cheaper night rate, higher day rate; single standing charge. Homes with storage heaters or EV charging at night (high night usage share). If you don’t use enough at night, total cost can be higher than single-rate.
Time-of-use (smart tariffs) Prices vary by time/day; often requires smart meter. EV owners, flexible households who can shift use off-peak. Complex pricing; peaks can be expensive; not suitable if you can’t shift usage.

Decision checklist (who it suits / who it doesn’t)

Likely to suit you

  • You know your approximate annual kWh (so comparisons are meaningful)
  • You can pay by Direct Debit (often best-priced)
  • You want to avoid overpaying on standing charge after the cut
  • You’re happy to review again if rates change

May not suit you (or needs care)

  • You’re on prepayment and have limited tariff choice (it’s improving, but still different)
  • You have Economy 7 but most usage is daytime (single-rate may be cheaper)
  • You’re tempted by “cheap” headlines that ignore regional pricing and standing charges
  • You might move soon and a fix has high exit fees

Quick checks before switching

  • Is the quote for your region (postcode) and payment method?
  • Does it match your meter type (single vs two-rate)?
  • Are there exit fees and when does the tariff end?
  • Are you comparing estimated annual cost using your kWh?

Costs, exclusions and common pitfalls (UK-specific)

Standing charge changes can make comparisons feel confusing. These are the most common issues we see when people try to find the cheapest electricity tariff.

1) Comparing unit rates but ignoring standing charge

After a cut, standing charges are lower, but they’re still a meaningful part of the bill — especially for low usage. Always compare the estimated annual cost, not just p/kWh.

2) Not accounting for regional price differences

Electricity rates vary by region (your local distribution area). A tariff headline price may not match what you can get in your postcode.

3) Payment method differences (Direct Debit vs others)

Many suppliers price tariffs differently depending on whether you pay by monthly Direct Debit, receipt of bill, or prepayment. Make sure quotes match how you actually pay (or how you plan to pay).

4) Economy 7: the split matters

With Economy 7, the “cheapest” tariff depends on your day vs night usage. If you can’t estimate your split, start by checking a bill or asking your supplier.

5) Exit fees and moving home

Fixed tariffs can be competitive, but check exit fees. If you’re renting or might move, consider flexible or no-exit options where suitable.

6) “Cheapest” doesn’t mean “best for you”

Service levels, billing accuracy, and support matter. If two tariffs are close, consider supplier reputation and support channels alongside price.

Important: If you’re in debt to your current supplier, you can often still switch, but there may be limits (especially for prepayment). If you’re struggling to pay, get free, impartial help from Citizens Advice energy guidance.

FAQs

What is a standing charge, and why does it change?

A standing charge is a daily fixed cost for your energy supply (separate from unit rates). It can change due to regulatory updates, network costs, supplier pricing decisions, and market conditions. It also varies by region and payment method.

Does a standing charge cut mean my bill will definitely fall?

Not necessarily. If the standing charge falls but the unit rate rises (or your usage increases), your total bill may not drop. The only reliable way to tell is to compare estimated annual cost using your kWh.

What’s the cheapest tariff type right now: fixed or variable?

It depends on what suppliers are offering in your region at the time you compare. Fixed deals can beat the SVT, but not always. Variable tariffs can be competitive and flexible, but prices can change. Compare both using the same usage assumptions.

Do I need a smart meter to get the cheapest electricity tariff?

No. Many competitive tariffs are available without a smart meter. However, some time-of-use tariffs require one, and they only suit you if you can shift usage to cheaper times.

I’m on Economy 7 — should I switch to a single-rate tariff after the cut?

Possibly, but base it on your day/night usage. Economy 7 tends to work best when a meaningful share of your electricity is used overnight (e.g., storage heaters or EV charging). If most of your usage is daytime, a single-rate tariff can be cheaper overall.

Can I switch electricity supplier if I rent?

In most cases, yes — if you pay the energy bills and have a standard domestic supply. You usually can’t change the meter or make physical alterations without permission, but switching supplier is normally allowed. If bills are included in rent, the landlord may control the supply contract.

Will switching affect my electricity supply?

No. Your electricity keeps flowing; only the company billing you changes. Switches are designed to be seamless, though you should provide accurate meter readings when asked (unless you have a working smart meter sending reads).

What should I check on a tariff before I agree to switch?

Confirm: unit rate(s), standing charge, contract length, exit fees, payment method pricing, and whether it’s fixed or variable. Also check any eligibility rules (for example, smart-meter requirement for certain tariffs).

How we assess “cheapest” (methodology), plus trust & sources

Trust details

Our approach (plain English)

When we say “cheapest”, we mean lowest estimated annual cost for your household, based on:

  • Standing charge (p/day) × 365
  • Unit rate (p/kWh) × annual usage (kWh) — or day/night split for Economy 7
  • Tariff structure (fixed, variable, time-of-use) and any eligibility requirements
  • Payment method (e.g., Direct Debit vs prepayment) and region (postcode)

We prioritise like-for-like comparisons and highlight trade-offs such as exit fees and suitability for your meter type.

Limitations and caveats

  • Tariffs can change frequently; a “cheapest” result is time-sensitive.
  • Prices vary by region, meter type and payment method.
  • Time-of-use tariffs may require a smart meter and depend on when you use electricity.
  • Any scenario figures on this page are illustrative and not a quote.
