What is Ofgem’s standing charge cap proposal?

Ofgem’s standing charge cap proposal is a potential change to the price cap rules that would limit (cap) the daily standing charge on energy bills. Standing charges are the fixed daily amounts you pay for having a gas and/or electricity supply, regardless of usage. If introduced, a cap could reduce the fixed part of bills for many households.

Who would save the most if standing charges are capped?

Typically, low-energy users and smaller households (including people who live alone, some flats, and homes that use less gas/electricity) benefit most from lower standing charges because a larger share of their bill is fixed costs. High-energy users may see smaller savings from a standing charge cap, depending on whether any costs are shifted into unit rates.

Would a standing charge cap reduce my overall energy bill?

It could, but it depends on how the policy is implemented. If standing charges are capped and the remaining costs are not moved into unit rates, many customers would pay less overall. If some costs are recovered through higher unit rates, lower users may still save while higher users could see less benefit.

What is a standing charge and why do suppliers charge it?

A standing charge is a fixed daily fee that helps cover costs such as maintaining the energy network, meter reading, operating customer service, and policy costs. It applies even if you use no energy on a given day.

Will a standing charge cap affect electricity and gas prices the same way?

Not necessarily. Electricity and gas have separate standing charges and unit rates, and changes could be applied differently depending on Ofgem’s final decision. Your impact will depend on whether you have electricity only, gas only, or dual fuel, and your usage levels for each.

Could unit rates increase if standing charges are capped?

Possibly. If the overall amount suppliers need to recover stays the same, limiting standing charges could mean some costs shift to unit rates (the price per kWh). That would tend to favour lower users and reduce the benefit for higher users.

How can I estimate whether I’ll save under a standing charge cap?

Compare how much you currently pay in standing charges (daily charge × 365) against the proposed cap level, then consider how any unit-rate changes might affect your annual kWh costs. The quickest way is to check your latest bill for standing charge and annual usage, then model a lower standing charge and a possible unit rate adjustment.

What can I do now to reduce my energy costs?

You can often reduce costs by reviewing your tariff, comparing suppliers, and choosing the best value fix or variable deal for your usage. If you have a smart meter, use it to understand peak usage. To see potential savings, compare energy deals here: https://www.energyplus.co.uk/

Is the standing charge cap confirmed and when would it start?

It’s a proposal, so timings depend on Ofgem’s consultation process and final decision. If adopted, it would typically be introduced in a future price cap period. Keep an eye on updates and consider switching if a better tariff is available in the meantime.

Ofgem standing charge cap proposal: who saves most?

If Ofgem caps standing charges, it could reduce fixed daily costs on energy bills — but the biggest winners may not be the households you’d expect. This guide explains who’s likely to benefit most, what could change on your unit rates, and how to check your options safely.

Fast answer: who’s most likely to save if standing charges are capped?

A cap on standing charges generally benefits households that pay the standing charge every day but use relatively little energy. That often includes people in smaller homes, single occupants, some flat-dwellers, and households who are extremely careful with usage.

Most likely to benefit

Low users of gas/electric (standing charge forms a large share of the bill)
Electricity-only homes (especially if heat is not gas)
Some prepayment customers (depending on how any cap is designed)
Households in higher-standing-charge regions (today’s regional variation matters)

May benefit less (or see trade-offs)

High-usage households (savings may be smaller compared to total spend)
All-electric heating / EV charging homes (unit rates matter more)
Anyone on a fix with a very low unit rate already (switching could change that)
Homes with multiple meters / complex setups (standing charges may apply per meter)

Key takeaway

If standing charges are capped, suppliers may recover some revenue elsewhere (for example, via unit rates). So the best outcome for you depends on your usage level, payment method, meter type and region — not just the headline standing charge.

Important: Ofgem’s standing charge cap is a proposal (not a guaranteed change). Details such as the cap level, which tariffs it applies to, and whether unit rates rise in response can materially affect who saves.

Check what you could pay (without guessing)

If standing charges change, the “best” tariff can change too — especially for low users. Compare whole-of-market home energy deals based on your postcode, payment method and meter type.

What you’ll need

Your postcode
Rough annual usage (or a recent bill)
Whether you pay by Direct Debit, cash/cheque, or prepay
Meter info (smart, standard, Economy 7, etc.)

Why it matters

Standing charges vary by region and fuel
Unit rates can move in the opposite direction
Prepay and Economy 7 can price differently
Exit fees may apply on fixed deals

Tip: If you’re on a fixed tariff, check whether there’s an exit fee before switching. A standing charge cap (if introduced) would typically affect the price cap level, but your fix may not automatically change.

Who saves most under a standing charge cap (and why)

Standing charges are fixed daily costs that help fund networks and other system costs. Because they’re charged regardless of usage, they hit low users hardest as a percentage of their bill. A cap would typically reduce those fixed charges — but it may also lead to changes elsewhere (often via unit rates).

High standing charge, low usage = biggest proportional gain

If your usage is low, reducing the standing charge can be a meaningful share of your annual bill. Typical examples include a one-bedroom flat, a single occupant, a second home with minimal usage, or a household that’s out at work most days.

Electricity-only homes may see clearer impact

With only one fuel, any cut to the electricity standing charge is easier to “feel” in your monthly cost. Dual-fuel homes could benefit on both meters — but unit-rate trade-offs could also apply to both.

Scenario 1: low-use flat (electricity-only)

Assumptions (illustrative): 1,800 kWh/year electricity; single-rate meter; monthly Direct Debit. Current standing charge 60p/day. Proposed cap reduces it to 35p/day. To keep overall revenue similar, unit rate increases by 1.5p/kWh.

Estimated annual change:
Standing charge: (0.60 - 0.35) × 365 = £91.25 saving
Unit rate: 0.015 × 1,800 = £27.00 increase
Net estimated saving: £91.25 - £27.00 = £64.25/year

What this shows: a standing charge cut can outweigh a modest unit-rate increase for low users.

Scenario 2: family home (gas + electric, higher usage)

Assumptions (illustrative): 3,600 kWh/year electricity and 12,000 kWh/year gas; Direct Debit. Electricity standing charge 60p/day to 35p/day (cap). Gas standing charge 32p/day to 20p/day. Unit rates rise by 1.5p/kWh (electric) and 0.35p/kWh (gas).

Estimated annual change:
Standing charges: Elec (0.25×365)=£91.25 saving; Gas (0.12×365)=£43.80 saving; Total £135.05 saving
Unit rates: Elec 0.015×3,600=£54.00 increase; Gas 0.0035×12,000=£42.00 increase; Total £96.00 increase
Net estimated saving: £135.05 - £96.00 = £39.05/year

What this shows: higher users can still save, but the unit-rate trade-off can reduce the benefit.

Reality check: These are not forecasts of Ofgem’s final numbers. They’re examples to explain the mechanics. Actual changes would depend on Ofgem’s final design, your region, your supplier, meter type (including Economy 7 and prepay), and how suppliers set tariffs.

Quick comparison: who tends to gain most from a standing charge cap?

Use this table as a practical guide. Your actual outcome still depends on your tariff’s unit rate and standing charge, plus regional price cap levels.

Household type	Typical usage pattern	Why a cap could help	What to watch
Low-use flat (electricity-only)	Low annual kWh; standing charge is a big share	Lower fixed daily cost can materially reduce bill	Unit rate rises can offset savings; check single vs Economy 7
Dual-fuel, moderate usage	Average gas heating and normal electricity use	You’d save on two standing charges (gas + electric)	Any unit-rate increases apply to both fuels
High-use home (kids, home working)	High kWh; usage dominates total cost	Standing charge saving still exists, but smaller vs total spend	Even small unit-rate rises can outweigh standing charge cuts
All-electric heating / EV charging	Very high electricity kWh; time-of-use may matter	Lower electricity standing charge helps, but often not the main driver	Unit rates/time bands are critical; cap may not improve your best deal
Prepayment customer	Often pays higher costs; budgeting is key	Lower fixed daily charge could reduce the “always on” cost	Rules can differ by meter and supplier; check debt recovery settings

Decision checklist (60 seconds)

Is your usage low? (Standing charge makes up a big part of your bill.)
Do you have gas + electric? (You pay two standing charges.)
Are you on prepay or Economy 7? (Pricing structures can differ.)
Are you in a high-standing-charge region? (Your postcode matters.)
Are you on a fixed tariff with exit fees? (Switching may not be worth it.)

If you want one action to take

Find your current standing charge and unit rate (on your bill or in-app), then compare tariffs based on your typical usage.

Costs, exclusions and common pitfalls

A standing charge cap sounds simple, but real bills are shaped by several UK-specific factors. These are the most common reasons people don’t see the savings they expect.

1) Unit rate trade-off

If suppliers recover revenue via higher unit rates, high-usage homes may see smaller net savings (or none). Always compare annual cost, not just standing charge.

2) Region and network costs

Price cap values vary by region. Two households with the same usage can have different standing charges due to local distribution costs.

3) Payment method differences

Direct Debit, standard credit, and prepayment can price differently. A cap might apply differently depending on how Ofgem designs it.

4) Economy 7 / multi-rate meters

If you have Economy 7 (day/night rates) or a time-of-use tariff, a standing charge change may be less important than the split between your day and night usage.

5) Fixed tariff exit fees

Some fixed tariffs include exit fees. Even if a cap reduces future standing charges, switching early might not be worthwhile if fees outweigh the estimated benefit.

A quick “bill check” you can do today

Find your standing charge (p/day) and unit rate (p/kWh) for each fuel on your latest bill.
Estimate your annual standing charge cost: standing charge × 365.
Estimate your annual usage cost: unit rate × annual kWh (use your bill’s annual figures if available).
Compare tariffs using the same annual usage so you’re comparing like-for-like.

FAQs

What is a standing charge (in plain English)?

It’s a fixed daily cost you pay to have an energy supply, regardless of how much you use. It contributes to network and system costs and can differ by region, fuel and payment method.

If Ofgem caps standing charges, will my bill definitely go down?

Not definitely. A lower standing charge reduces fixed costs, but suppliers could adjust unit rates. Whether you save overall depends on your usage, tariff type and region.

Does the price cap mean my tariff is capped?

The Ofgem price cap limits the maximum rates for typical standard variable (default) tariffs, and it influences the wider market. Fixed tariffs can be above or below the cap, and their prices won’t automatically change unless the tariff terms allow.

Do standing charges differ across the UK?

Yes. Electricity standing charges and unit rates vary by region because local network costs differ. That’s why postcode-based comparisons are important.

What if I’m on prepayment?

Prepay pricing can differ from Direct Debit tariffs. A cap could help, but outcomes depend on the final policy design and supplier pricing. Also check whether any meter debt repayments are being taken from top-ups, as that can affect what you experience week-to-week.

I have Economy 7. Does a standing charge cap matter as much?

It can still matter, but Economy 7 outcomes are often driven by your day/night split and the difference between the two unit rates. If most of your usage is daytime, an Economy 7 tariff may not suit you even with a lower standing charge.

Should I switch now or wait?

It depends. If you’re on an expensive standard variable tariff and a competitive fix is available, switching could still reduce your costs. If you’re already on a good fix, check exit fees and remaining term before making changes based on a proposal.

Is there anyone a standing charge cap could disadvantage?

Potentially. If unit rates rise to compensate, households with higher usage (including some medically vulnerable households with high electricity needs) could see less benefit. That’s why it’s important to look at total estimated annual cost, not one line of the bill.

How we assess “who saves most”

We assess likely beneficiaries by looking at how a change to the standing charge would affect households with different annual usage (kWh) and meter/payment types, while allowing for the realistic possibility that unit rates could change in the opposite direction.

Core idea: standing charges are fixed; so savings are proportionally bigger for low users.
What we modelled in examples: a standing charge reduction paired with a modest unit rate increase to illustrate the trade-off.
What we did not do: predict Ofgem’s final cap level or supplier behaviour; these are illustrative mechanics, not forecasts.
UK specifics considered: regional pricing differences, dual-fuel vs electricity-only, and the reality of prepayment and multi-rate tariffs.

Limitations: Your exact standing charge and unit rates depend on where you live, how you pay, your meter setup, and your tariff. If you have multiple meters (for example, separate supplies), standing charges may apply more than once.
