What is Ofgem’s standing charge cap proposal?

Ofgem is consulting on changes that could place a cap on energy standing charges (the fixed daily fee on your bill). If introduced, this could shift some costs away from fixed charges and into unit rates, depending on the final policy design.

What is a standing charge and why does it matter?

A standing charge is a fixed amount you pay each day to cover network costs, metering and other charges, regardless of how much energy you use. It matters because it can make bills higher for low-usage households and affects the value of switching tariffs.

How does the standing charge cap proposal calculator work?

You enter (or estimate) your current standing charge and energy usage. The calculator then models how your bill could change if standing charges were reduced (or capped) and the difference was reflected in unit rates. It provides an indicative comparison to help you understand possible outcomes.

Will a standing charge cap make my energy bill cheaper?

Not always. If standing charges fall but unit rates rise to recover costs, low-usage households may benefit while higher-usage households may pay the same or more. Your result depends on how much gas and electricity you use and the final rules Ofgem introduces.

Who could benefit most from lower standing charges?

Typically, households with lower overall energy consumption (for example, smaller homes, single occupants, or people who are often away) may benefit more if fixed charges are reduced. High-usage homes may see less benefit if more cost moves into unit rates.

Does the standing charge cap apply to prepayment meters?

Ofgem consultations can include different approaches for credit and prepayment customers. Whether and how a cap applies to prepayment meters depends on the final decision. Use the calculator as a guide and check your meter type and tariff details when comparing options.

Is this calculator official or guaranteed to match future bills?

No. It’s an estimate designed to help you understand potential bill impacts under different standing charge scenarios. Actual bills will depend on Ofgem’s final policy, your supplier’s tariff structure, and future price cap levels.

What should I do if the calculator suggests I’d pay more?

If your costs could rise under a standing charge cap, consider ways to reduce usage (insulation, heating controls, efficiency measures) and review your tariff options. You can also compare business energy or home energy options with Energy Plus to see what rates are available for your situation.

How can I compare my current standing charge and unit rates?

Check your latest bill, online account, or smart meter in-home display. Look for the ‘standing charge’ (p/day) and ‘unit rate’ (p/kWh) for both electricity and gas. Comparing these figures helps you understand what a standing charge cap could change.

Fast answer: what a standing charge cap could change

Ofgem has explored options to reduce and/or cap standing charges (the daily fixed amount you pay regardless of usage). If a cap were introduced, your bill could go down, stay similar, or shift between standing charge and unit rates depending on how suppliers recover costs.

Important: A cap on standing charges does not automatically mean lower total bills. Suppliers could (partly) increase unit rates, and impacts vary by region, meter type and payment method.

Key takeaway 1

If you use low energy (small flats, single occupants, well-insulated homes), a lower standing charge can matter more.

Key takeaway 2

If unit rates rise to compensate, high-usage households could see little benefit or even pay more.

Key takeaway 3

The best move today is still to compare whole-of-market tariffs on your actual postcode and meter details.

Standing charge cap estimator (proposal-style)

This is a simple estimator to help you understand the direction of travel. You choose the standing charge amounts you want to compare, then we show the annual difference.

How the estimator works

Step 1: Pick fuel type (electricity/gas/both) and your current standing charge(s) in pence per day.
Step 2: Enter the proposed cap standing charge(s) in pence per day.
Step 3: We calculate the annual difference: (current - cap) × 365. This isolates the standing charge element only.

Quick example (electricity)

If your standing charge is 60p/day and a cap were 45p/day, the standing charge portion would be ~£54.75/year lower (15p × 365).

What it doesn’t show

It does not predict whether unit rates would increase. Use it as an aid, then compare real tariffs for your postcode.

Tip: You can find your standing charge on a recent bill, in your online account, or within your tariff information label. It’s usually shown in p/day and can differ for electricity vs gas.

Estimator inputs (use your own numbers)

Fuel type

Standing charges are applied separately for each fuel.

Electricity standing charge today (p/day)

Electricity proposed cap (p/day)

Gas standing charge today (p/day)

Gas proposed cap (p/day)

This page provides the method and examples. If you want a personalised tariff comparison using your postcode and meter details, use the quote form alongside.

Two realistic scenarios (with assumptions)

Scenario A: low-usage flat (electricity only)

Current standing charge: 60p/day
Illustrative cap: 40p/day
Estimated standing charge change: 20p × 365 = £73.00/year lower

Assumption: unit rates unchanged. In practice, unit rates could move, changing the total outcome.

Scenario B: family home (dual fuel)

Electricity: 62p/day ? 45p/day (-17p)
Gas: 32p/day ? 27p/day (-5p)
Estimated standing charge change: (17p + 5p) × 365 = £80.30/year lower

Assumption: changes apply evenly all year. Actual bills still depend heavily on unit rates and usage.

Compare tariffs on your details (whole of market)

If you’re deciding whether to act now, the most reliable step is to compare current tariffs for your postcode, payment preference and meter setup.

First name

Surname

Postcode

We use this to show prices for your region and network costs.

Telephone (optional)

Useful if you want help understanding meter or tariff options.

How do you usually pay?

Meter type (best guess)

No obligation. Prices and eligibility vary; we’ll show options based on the details you provide.

Why this matters for standing charge changes: standing charges are affected by region (network area), meter setup, and sometimes payment method. Your comparison should reflect those factors, not national averages.

Compare the outcomes: cap vs no cap (what to look at)

A standing charge cap could shift how costs are collected. Use the table below to sense-check what a change might mean for your household and what to verify when you compare tariffs.

What changes?	Likely winners	Likely losers	What to check when comparing
Standing charge is capped/lowered	Low-usage homes; empty properties paying daily charges year-round	If unit rates rise, higher-usage homes may see little net benefit	Total annual cost for your usage (kWh), not just p/day
Unit rate increases to recover costs	Still potentially low-usage (less kWh exposure)	Electric heating users; larger families; EV charging at home	p/kWh by fuel and (if applicable) day/night rates
Regional differences remain	Depends on your network area; some areas currently have higher standing charges	Households expecting a national “one price” outcome	Your postcode region and tariff information label
Different treatment by payment type/meter	Some proposals consider fairness across payment methods	If you’re on prepayment or Economy 7, comparisons can be less like-for-like	Eligibility, meter type, prepayment availability, time-of-use structure

Decision checklist (quick)

Know your meter: smart/standard, single-rate vs Economy 7, prepayment.
Check your payment method: Direct Debit vs prepay vs on receipt of bill.
Use your usage: annual kWh for electricity and gas (from your bill or online account).
Compare total annual cost: standing charge + unit rates, not one number alone.
Check exit fees: fixed deals may charge to leave early.
Confirm eligibility: some tariffs exclude prepayment or certain meter types.

Who a cap could suit (and who it may not)

May suit: low usage, second homes, people trying to reduce fixed costs.

May not: very high usage if unit rates rise materially; Economy 7 users if the structure changes.

These are general patterns. Your actual outcome depends on tariff prices available in your region.

Costs, exclusions and common pitfalls

Pitfall 1: focusing only on the standing charge

A lower standing charge can be offset by higher unit rates. Always compare the estimated annual cost using your kWh figures.

Pitfall 2: assuming it’s the same everywhere

Standing charges vary by region/network area. National headlines often quote averages; your postcode can differ.

Pitfall 3: exit fees on fixed tariffs

If you’re on a fixed deal, check for early exit fees. A future policy change may not justify switching today if fees outweigh benefits.

Exclusions to be aware of

Prepayment: some tariffs aren’t available for prepay meters, and pricing can differ.
Economy 7 / time-of-use: you have more than one unit rate; a simple “average” comparison may mislead.
Smart meter requirements: some tariffs (especially time-of-use) require a working smart meter.
Billing method: Direct Debit vs pay on receipt can change prices for some tariffs.
Debt on meter: switching may have additional steps if you owe your current supplier (especially prepayment).

If you’re struggling to pay

A standing charge change is policy-level and may take time. If you need help now, you may be able to access support such as payment plans, emergency credit (prepay), or grants.

FAQs

What is a standing charge on UK energy bills?

A standing charge is a daily fixed cost for each fuel (electricity and/or gas). It helps cover things like maintaining the networks, metering, and other system costs. You pay it even if you use no energy that day.

Is Ofgem definitely bringing in a standing charge cap?

Not necessarily. Ofgem may consult on options, revise proposals, or choose alternative measures. This page helps you estimate impacts if standing charges were capped — it isn’t a prediction or guarantee.

Would a cap lower my total bill?

It could, but it depends. If suppliers recovered costs through higher unit rates, high-usage households might see smaller benefits. The most accurate check is comparing tariffs on your postcode, meter type and usage.

Why do standing charges differ by region?

A large part of the standing charge relates to network costs, which vary by distribution region. That’s why two households on similar tariffs can still have different standing charges in different parts of Great Britain.

Does the Ofgem price cap include standing charges?

Yes. Ofgem’s energy price cap sets limits on the overall level of charges suppliers can levy for standard variable tariffs, including how standing charges and unit rates are set within the cap methodology. A separate standing charge cap would be an additional design change.

Do prepayment customers have different standing charges?

Often, yes. Prices can differ for prepayment compared with Direct Debit, and tariff availability is narrower. If you’re on prepay, it’s especially important to compare like-for-like.

What if I have Economy 7 or a time-of-use tariff?

You’ll have more than one unit rate (e.g., day and night). A standing charge change could interact with how those rates are set. Compare using your actual split of usage if you can (or ask your supplier for it).

Should I switch now or wait?

If you can find a tariff that suits your needs today (price certainty, customer service, features) it may be worth switching — but check exit fees and your current deal end date. Policy changes can take time and aren’t guaranteed to reduce bills for everyone.

How we assess this (methodology), plus sources

Our approach

People-first intent: we separate what you can estimate (standing charge change) from what you cannot (future unit rates).
Transparent maths: annual standing charge impact is calculated as (current p/day - capped p/day) × 365, converted into pounds.
UK-specific factors: we highlight how region, payment method, meter type (including Economy 7 and prepay) affects outcomes.
Decision support: we include a checklist and comparison table to help you avoid common traps.

Limitations (what this page can’t do)

It does not forecast Ofgem decisions or implementation dates.
It does not predict how suppliers might rebalance standing charges vs unit rates.
It does not replace a personalised quote based on your postcode and consumption.

If you want a like-for-like comparison, use your annual kWh figures (electricity and gas) and compare the estimated annual cost across tariffs.
