Ofgem standing charge cap proposal: who would save?
A clear, UK-focused guide to what a cap on standing charges could mean for different households — with examples, caveats, and how to compare tariffs safely.
- Best for low energy users (often single-person homes, some flats, or homes away a lot)
- Not always a win: any “lost” standing charge may be shifted into higher unit rates
- Payment method, meter type and region can still affect what you pay
Figures on this page are estimates for illustration. Standing charges and unit rates vary by region, payment method, meter type and supplier.
Fast answer: who is most likely to save if standing charges are capped?
If Ofgem introduced a cap that lowers standing charges, households that use less gas/electricity typically benefit the most — because standing charges are a larger share of their bill. However, a cap doesn’t automatically mean bills fall for everyone: suppliers may recover some costs by raising unit rates (pence per kWh), which can reduce or reverse savings for higher users.
More likely to save
- Low energy users (e.g. some single-person homes, smaller flats, homes empty in daytime)
- Homes with good insulation and lower heating demand
- Households who use electric-only but modestly (e.g. small flat) and feel standing charges are disproportionate
May save less (or pay more)
- Higher energy users (large homes, electric heating, poor insulation)
- Anyone whose supplier increases unit rates to offset lower standing charges
- Customers with limited ability to switch (e.g. certain meter setups or tariff constraints)
Important: Ofgem discussions have included different options (for example, reducing standing charges, introducing a cap, or offering alternatives). The impact depends on the final design and how suppliers price tariffs afterwards. Always compare using your usage in kWh, not just headline standing charges.
Compare tariffs the right way (standing charge vs unit rate)
A lower standing charge can look attractive, but your total cost depends on both:
- Find your annual usage in kWh (electricity and, if you have it, gas) from a recent bill, statement, or your online account.
- Check your payment method (Direct Debit, Pay on Receipt/standard credit, or prepayment). Price cap levels differ.
- Compare total estimated annual cost, not just the standing charge line.
- Check tariff terms: fixed vs variable, exit fees, and whether rates can change.
If you’re unsure of your usage, you can still compare — but your results will be more accurate if you enter real kWh figures (especially when standing charges change).
Two realistic scenarios (with numbers)
These examples show why low users tend to gain from a lower standing charge, and why higher users can see smaller savings if unit rates rise. They’re illustrative only (rates vary by region, supplier, meter type and payment method).
Scenario A: low user (electricity only)
- Annual usage
- 1,500 kWh
- Current standing charge
- 60p/day
- Current unit rate
- 25p/kWh
Estimated current annual cost = (0.60×365) + (0.25×1,500) = £219 + £375 = £594
Illustrative cap outcome: standing charge falls by 20p/day to 40p/day, and unit rate rises by 1p/kWh to 26p/kWh.
Estimated new annual cost = (0.40×365) + (0.26×1,500) = £146 + £390 = £536
Estimated change: £58/year cheaper (about £4.80/month)
Scenario B: higher user (gas + electricity)
- Elec usage
- 3,600 kWh
- Gas usage
- 12,000 kWh
- Elec standing charge
- 60p/day
- Gas standing charge
- 32p/day
- Elec unit rate
- 25p/kWh
- Gas unit rate
- 6.5p/kWh
Estimated current annual cost = (0.60×365)+(0.32×365)+(0.25×3,600)+(0.065×12,000) = £219+£117+£900+£780 = £2,016
Illustrative cap outcome: elec standing charge falls 20p/day, gas standing charge falls 10p/day; unit rates rise by 1.5p/kWh (elec) and 0.4p/kWh (gas).
Estimated new annual cost = (0.40×365)+(0.22×365)+(0.265×3,600)+(0.069×12,000) = £146+£80+£954+£828 = £2,008
Estimated change: £8/year cheaper (nearly neutral)
What to take from these examples: the lower your usage, the more a standing charge reduction can matter. The higher your usage, the more sensitive you are to unit rate increases.
Get a comparison (whole-of-market)
Tell us a few details and we’ll show tariffs that fit your home. It’s the simplest way to see whether a lower standing charge would likely help you once unit rates are factored in.
Tip: If you’re on a fixed tariff, check for exit fees before switching. If you have a smart meter on prepay, confirm whether your chosen tariff supports it.
Quick comparison: who benefits most from a standing charge cap?
This table is a practical way to judge whether a lower standing charge is likely to help you. Your outcome depends on how much the unit rate changes and how much energy you use.
| Household pattern | Standing charge share of bill | If standing charge falls… | …but unit rates rise | Likely result |
|---|---|---|---|---|
| Low user (small flat, often out) | Higher | Can reduce a meaningful fixed cost | Less energy purchased, so impact smaller | More likely to save |
| Typical user (average home) | Medium | Some savings possible | Could offset part of the standing charge drop | Depends on tariff |
| High user (large home, electric heating, poor insulation) | Lower | Standing charge change matters less | More kWh means increases can outweigh savings | May save little / may pay more |
| Two-meter / complex setup (e.g. some legacy multi-rate tariffs) | Varies | Harder to predict | Tariff rules can dominate outcomes | Get tailored quotes |
Decision checklist: it probably suits you if…
- You use low gas/electricity and standing charges feel disproportionate
- You can switch to a tariff with competitive unit rates as well as a lower standing charge
- You’re happy to compare using kWh (not just headline “daily charge”)
It may not suit you if…
- You’re a high user and any unit rate increase would hit hard
- You’re on a fixed deal with exit fees that outweigh likely savings
- Your meter/tariff type makes switching options limited (check before you commit)
Costs, exclusions and common pitfalls to watch
Standing charge reforms can be confusing because different costs can move around the bill. These are the key gotchas UK households run into.
1) Unit rates may rise
If standing charges are capped lower, suppliers may price more cost into the p/kWh unit rate. That can dilute savings for medium/high users. Compare using your annual kWh.
2) Your region still matters
Standing charges and unit rates vary across Great Britain due to regional network costs. A cap could reduce differences, but it may not remove them.
3) Payment method affects prices
The price cap is set separately for Direct Debit, prepayment and standard credit. Always compare tariffs that match how you pay (or plan to pay).
4) Meter type can limit options
Some households have smart prepay, legacy multi-rate tariffs, or other setups that not every supplier supports. Confirm compatibility before switching.
5) Exit fees can wipe out gains
If you’re in a fixed tariff, check the exit fee per fuel. Compare the fee against the estimated annual saving before deciding.
6) “Zero standing charge” isn’t always best
Some tariffs market very low standing charges but have higher unit rates. They can suit very low users, but they’re often poor value for average usage.
If you’re struggling to pay: don’t wait for policy changes. You may be able to get help now (repayment plans, emergency credit for prepay, or support schemes). See Citizens Advice guidance in the sources below.
FAQs
What is a standing charge and why do we pay it?
A standing charge is a daily fixed amount that helps cover costs such as maintaining energy networks, metering, and supplier operating costs. You pay it even if you use no energy that day.
Would an Ofgem cap guarantee my bill goes down?
No. A cap that lowers standing charges could reduce your fixed costs, but suppliers may adjust unit rates. Your total depends on your kWh usage, region, payment method and tariff type.
Do standing charges differ across the UK?
Yes, across Great Britain they vary by region due to different network costs. (Northern Ireland has separate arrangements and regulators.) Payment method and meter type can also change the level you see.
I barely use energy — can I reduce standing charges today?
Potentially, by switching to a tariff with a lower standing charge, but always check the unit rate. A tariff with a very low standing charge can have a higher p/kWh that makes it poor value at average usage.
Does the Ofgem price cap set my exact tariff prices?
No. It limits the maximum suppliers can charge for default tariffs (like standard variable tariffs) for typical consumption assumptions, and is expressed as unit rates and standing charges. Fixed deals can be priced differently.
Could a cap affect prepayment customers differently?
Possibly. Price cap levels are set separately for prepayment (including smart prepay). If standing charges reduce and unit rates rise, low-usage prepay customers may benefit more than higher-usage households — but it depends on the final rules and supplier pricing.
What if I have debt on my energy account?
You can often still switch, but it depends on your situation (especially for prepay). If you’re in difficulty, speak to your supplier and consider free advice from Citizens Advice before making changes.
What’s the single best way to judge if I’d save?
Run a comparison using your annual kWh usage and your postcode. Then compare the total estimated annual cost across tariffs — not only the standing charge line.

How we assess “who would save”
We focus on the underlying bill maths:
- Annual cost ˜ (standing charge × 365) + (unit rate × annual kWh)
- If standing charges fall but unit rates rise, your break-even point depends on how many kWh you use.
For the scenarios on this page, we used simple illustrative inputs to show the direction of change:
- Standing charges and unit rates shown are example figures, not a forecast.
- We modelled a standing charge reduction alongside a plausible unit-rate increase to demonstrate sensitivity.
- We assume 365 billing days and standard annual usage totals in kWh for each scenario.
Limitations (please read)
- Policy design matters: a “cap” could mean different things (e.g. maximum standing charge level, rebalancing between standing charge and unit rate, or targeted changes). Outcomes vary.
- Not all households can switch easily: meter type, debt position, or tariff constraints may affect options.
- Regional variation remains important for network costs and therefore standing charges/unit rates.
- We don’t account for rebates/support schemes, time-of-use tariffs, or unique metering arrangements in the simplified examples.
