Fast answer: a standing charge cap helps some households — but it can shift costs elsewhere
Ofgem’s standing charge cap proposal (as consulted on) is designed to reduce the fixed daily charge many households pay for gas and electricity. In practice, a cap usually means someone pays less in standing charges, but suppliers may recover the difference through higher unit rates (pence per kWh) or changes to how costs are shared.
More likely to win
- Low-use homes (e.g., small flats, single occupants, very efficient homes)
- Homes that use very little gas (e.g., electric-only properties)
- Some households who struggle with fixed charges even when they reduce usage
More likely to lose
- Higher-use homes (large families, older/less insulated homes)
- Homes with electric heating (often high electricity kWh usage)
- Anyone on a tariff where the supplier responds by raising unit rates
Key caveat: the impact depends on the exact cap design (e.g., “hard cap”, “zero standing charge option”, regional variation) and how suppliers rebalance prices. Always compare the total estimated annual cost, not just the standing charge.
What is the standing charge — and what is Ofgem proposing?
Your energy bill is typically made up of:
- Standing charge (pence per day)
- A fixed daily amount to cover things like network costs and supplier operating costs. You pay it even if you use no energy.
- Unit rate (pence per kWh)
- What you pay for each unit of gas/electricity you use.
What a “cap” could mean in real life
Ofgem already sets a broader price cap for default tariffs. A standing charge cap proposal would add additional limits or structures around the daily charge. Depending on the final rules, this could look like:
- Lower maximum standing charge allowed on certain tariffs
- More of the cost moved into unit rates (so bills depend more on usage)
- Optional “low/zero standing charge” tariffs with higher unit rates
Why this matters: if fixed costs move into unit rates, it can help low users but increase bills for people who can’t easily cut usage (e.g., families, electric heating, medical needs).
Compare tariffs the right way (not just the standing charge)
If a standing charge cap arrives, suppliers can still compete in different ways. The safest approach is to compare tariffs using your estimated annual usage and your property’s details.
Check 1: What meter type are you on?
Smart meter, standard credit, or prepayment can change which tariffs you can access and the rates you see.
Check 2: Do you have a multi-rate tariff?
If you’re on Economy 7 / multi-rate electricity, your night/day split matters more than the standing charge alone.
Check 3: Are you in a high standing charge region?
Standing charges vary by region (distribution area). A cap may narrow differences, but it won’t necessarily remove them.
Tip: find your annual kWh on a recent bill. If you’re not sure, use an estimate — but treat comparisons as indicative until you confirm usage.

Two realistic scenarios (with numbers)
Below are simplified examples to show why a standing charge cap can create winners and losers. They are illustrative estimates using the same methodology for both households.
Scenario A: Low-use flat (more likely to benefit)
- Electricity use: 1,800 kWh/year
- Gas use: 0 kWh/year (electric-only)
- Assumed current electricity standing charge: 60p/day
- Assumed current unit rate: 28p/kWh
Estimated annual cost today
Standing charge: 0.60 × 365 = £219
Unit cost: 1,800 × £0.28 = £504
Total: £723
Illustrative “capped” design
Standing charge reduced to 30p/day (-30p) but unit rate rises to 31p/kWh (+3p).
New standing charge: 0.30 × 365 = £110
New unit cost: 1,800 × £0.31 = £558
Total: £668 (about £55 less)
Scenario B: Family home (may pay more)
- Electricity use: 4,200 kWh/year
- Gas use: 12,000 kWh/year
- Assumed electricity: 60p/day & 28p/kWh
- Assumed gas: 32p/day & 7p/kWh
Estimated annual cost today
Elec standing charge: 0.60 × 365 = £219
Elec unit: 4,200 × £0.28 = £1,176
Gas standing charge: 0.32 × 365 = £117
Gas unit: 12,000 × £0.07 = £840
Total: £2,352
Illustrative “capped” design
Elec standing charge to 30p/day, unit to 31p/kWh; gas standing charge to 15p/day, unit to 8p/kWh.
New elec standing: 0.30 × 365 = £110
New elec unit: 4,200 × £0.31 = £1,302
New gas standing: 0.15 × 365 = £55
New gas unit: 12,000 × £0.08 = £960
Total: £2,427 (about £75 more)
What these examples show: a standing charge cap can act like a transfer from higher users to lower users if costs move into unit rates. Actual impacts depend on your tariff, region, meter type and the final Ofgem rules.
Who wins and who loses: quick comparison table
Use this as a decision aid. The “winner/loser” outcome is most likely where suppliers offset lower standing charges with higher unit rates.
| Household / situation | If standing charge falls… | …and unit rate rises | What to do next |
|---|---|---|---|
| Low electricity user (e.g., 1,500–2,500 kWh/yr) | Usually helpful | Often still benefits | Compare totals using your kWh; consider “low standing charge” options |
| High electricity user (e.g., 4,000+ kWh/yr) | Helpful on paper | Can lose overall | Prioritise unit rate; check Economy 7/multi-rate suitability |
| Low gas user (small/efficient home) | Likely helpful | Often still benefits | Compare gas standing charge vs unit rate; don’t ignore exit fees on fixes |
| High gas user (older/less insulated, family) | Some benefit | Higher chance of paying more | Run totals with your gas kWh; consider fixes with competitive unit rates |
| Prepayment meter | Could help affordability | Depends on tariff availability | Check payment method options; ask supplier about smart prepay tariffs |
| Electric heating (no gas, high kWh) | Standing charge cut may help | Unit rate rise can significantly hurt | Focus on unit rate; consider multi-rate if you can shift usage |
Decision checklist: it may suit you if…
- Your usage is low and the standing charge forms a big share of your bill
- You’re willing to accept a slightly higher unit rate for a lower fixed cost
- You want bills that are more sensitive to how much energy you actually use
It may not suit you if…
- Your home has high usage you can’t easily reduce (family size, health needs)
- You have electric heating and already pay high electricity kWh
- You’re comparing tariffs by standing charge only (risk of choosing a higher total cost)
Costs, exclusions and common pitfalls to watch
A standing charge cap sounds simple, but billing outcomes can be affected by tariff structure and eligibility. Here are the most common gotchas we see.
1) Higher unit rates can outweigh the cap
If the unit rate rises by a few pence per kWh, higher users can pay more overall even with a much lower standing charge.
2) Regional variation still matters
Standing charges vary by distribution region. A cap may reduce extremes, but different areas can still see different outcomes.
3) Payment method and meter type can limit choice
Some tariffs are only available to direct debit customers, smart meter users, or certain meter configurations (e.g., multi-rate).
4) Exit fees on fixed tariffs
If you’re on a fixed deal, check for exit fees before switching. A better standing charge doesn’t help if fees outweigh the benefit.
5) Multi-rate tariffs need a usage pattern match
Economy 7 can work if you use a meaningful share overnight. If not, a higher day rate can cancel out any standing charge benefit.
6) “Low standing charge” isn’t the same as “cheapest”
Some tariffs are marketed on a low standing charge but have unit rates that make them poor value for average or high usage homes.

FAQs: Ofgem standing charge cap proposal
Will a standing charge cap definitely reduce my bill?
Not necessarily. If the standing charge falls but unit rates rise, low users may benefit while higher users may pay more overall. Always compare the estimated annual total using your kWh.
Can suppliers increase unit rates if standing charges are capped?
Depending on the final rules, suppliers may rebalance how they recover costs (within any wider price cap rules that apply). That’s why the total cost is what matters, not one line item.
Does the standing charge differ across the UK?
Yes. Standing charges and unit rates vary by region (distribution area). They can also vary by payment method and meter type (e.g., prepayment vs direct debit).
What if I have a prepayment meter?
You can still compare tariffs, but availability can be more limited. If you have a smart prepayment meter, ask suppliers what tariffs are available and whether you can move to (or from) prepay without replacing your meter.
Could a cap affect customers with electric heating more?
Often, yes. Electric heating usually means higher electricity consumption. If unit rates rise to offset a lower standing charge, those extra kWh can add up quickly. Comparing unit rates becomes even more important.
Should I switch now or wait?
It depends on your current tariff, any exit fees, and the deals available to you today. If you’re on an expensive variable tariff, comparing fixed options can still be worthwhile. If you’re already on a competitive fix with exit fees, it may be better to review nearer the end of the term.
Are standing charges the same as the Ofgem price cap?
No. The Ofgem price cap limits the overall rates for default tariffs (including standing charge and unit rates). A standing charge cap proposal is specifically about limiting or restructuring the daily fixed charge.
What details do I need to do a proper comparison?
A postcode, fuel type (gas/electricity), meter type (smart/standard/prepay), whether you’re Economy 7/multi-rate, and your annual kWh (or a reasonable estimate). This lets you compare tariffs on a like-for-like basis.

How we assess who wins/loses
- We compare total annual cost under two pricing structures: “current-style” vs “lower standing charge + higher unit rate”.
- We test both low-use and higher-use households.
- We treat results as directional (not predictions) because supplier responses can differ.
Assumptions & limitations
- Illustrative rates are simplified and don’t represent all regions or suppliers.
- We exclude discounts, boiler cover bundles and time-of-use variants unless stated.
- Actual bills vary with weather, occupancy, and how much you can shift usage.
