Ofgem standing charge cap proposal 2026 calculator
Estimate how a potential Ofgem standing charge cap in 2026 could affect your household electricity and gas bills, then compare whole-of-market tariffs with EnergyPlus.co.uk.
- Get a clear estimate for electricity and gas (daily standing charge and unit rate impact)
- See who tends to gain most from a cap (low, medium, and high usage households)
- Submit your details once to compare whole-of-market options and switch if you want to
Estimates are illustrative only and not Ofgem advice. Standing charges and unit rates vary by region, meter type, and payment method.
Calculate the potential 2026 standing charge cap impact
Ofgem has discussed options that could reduce (or cap) the daily standing charge portion of bills. This page helps you estimate how a hypothetical cap might change your annual costs based on your usage, then lets you request a whole-of-market comparison to see today’s best available home tariffs.
How this calculator works: We ask for your postcode (to match regional standing charge bands), approximate annual usage, and whether you have gas. We’ll use these details to estimate a “current-like” baseline vs a “cap scenario” so you can see the potential difference.
Important: This is an estimate. Actual prices depend on supplier tariffs, payment method, meter type (including prepayment and smart meters), and future Ofgem decisions.
What you’ll get
- Estimated annual standing charge for electricity and (if applicable) gas
- Estimated annual energy cost from your unit rates and usage
- “Cap scenario” range to reflect uncertainty around 2026 policy
- Option to compare whole-of-market tariffs using the same details
Request your whole-of-market comparison
Fill in the form and we’ll send your personalised comparison and next-step options. No obligation to switch.
Tip: If you have a recent bill to hand, your annual usage (kWh) is usually shown for electricity and gas. If not, estimates are fine—your comparison can still be useful.
What the Ofgem standing charge cap proposal could mean in 2026
A standing charge is the fixed daily amount you pay to cover network costs and certain policy costs—regardless of how much energy you use. A standing charge cap (if introduced) could limit how high that daily charge can be, potentially shifting more of the cost recovery into unit rates (the price per kWh) or into other mechanisms.
Why Ofgem is looking at standing charges
- Standing charges have risen in recent years and are highly visible on bills.
- Low-usage households can feel disproportionate impact from fixed daily costs.
- There are fairness questions around how essential network costs are shared.
Why the impact isn’t always straightforward
- If standing charges fall, unit rates could rise to recover allowed costs.
- Regional differences (distribution networks) still matter.
- Different payment methods and meter types can have different pricing.
That’s why the best next step is to: (1) estimate your likely exposure based on your usage, then (2) compare current tariffs across the market and choose what fits your household now.
Who might benefit most from a standing charge cap?
A cap may help some households more than others. The key factor is how much of your annual bill is made up of standing charges vs unit rates.
Low usage households
If you use relatively little energy (for example, a small flat or a household that’s out all day), standing charges can be a larger share of your bill.
- Potentially more benefit if standing charges fall
- But watch for unit rate increases
Typical usage households
If your usage is around average, the effect can be mixed—your overall change depends on your tariff’s unit rate and how the cap is implemented.
- Small savings or small increases are both possible
- Comparing tariffs can make a bigger difference than the cap
High usage households
If you use lots of energy (larger homes, electric heating, many occupants), your bill is driven more by unit rates.
- Less benefit if savings are mainly on the standing charge
- More exposed if unit rates rise
Practical takeaway: Don’t rely on headlines. Your postcode region and your annual kWh usage are the two biggest inputs for a realistic estimate—then you can compare actual tariffs available to your home.
How to use this calculator alongside a whole-of-market comparison
Even if a standing charge cap is introduced in 2026, your costs between now and then depend on today’s unit rates, standing charges, and how well your tariff fits your usage pattern. Use the calculator for context—then compare real offers.
- Find your usage: from your bill or app (annual kWh for electricity and gas). If you don’t have it, use a best guess—this still helps.
- Enter your postcode: to reflect regional standing charge differences.
- Compare tariffs whole-of-market: look at total annual cost, not just the headline unit rate.
- Check tariff type: fixed vs variable, exit fees, and any incentives—then choose what suits your household.
- Switch when you’re ready: switching is usually straightforward and you won’t have your supply interrupted.
Quick reference: what to look for on a tariff
Standing charge cap: common misconceptions
- “A cap means everyone pays less.” Not always—costs can move into unit rates.
- “Standing charges are the same everywhere.” They vary by region and sometimes by meter/payment.
- “It only affects electricity.” There can be separate considerations for electricity and gas.
- “I should wait until 2026 to switch.” Many households can benefit from reviewing tariffs sooner.
Regional considerations (why postcode matters)
Standing charges can differ across Great Britain because electricity distribution networks vary by region. That’s why we ask for your postcode—it helps produce a more realistic estimate and a more accurate whole-of-market comparison.
Electricity region
Your distribution area influences daily standing charges and sometimes unit rates.
Meter & payment method
Credit, direct debit, and prepayment can have different price structures.
Single vs dual fuel
If you have both gas and electricity, you’ll typically have two standing charges.
If you’re in Northern Ireland
Energy regulation and tariffs differ in Northern Ireland. If your postcode is in Northern Ireland, your comparison options may differ from Great Britain.
FAQs: Ofgem standing charge cap proposal 2026
Is the standing charge definitely being capped in 2026?
No. It’s a proposal/discussion area and could change. This page provides estimates to help you understand the possible direction of travel and your exposure—not a guarantee of future prices.
If the standing charge goes down, will my bill go down?
Not automatically. If suppliers recover allowed costs elsewhere (often via unit rates), some households—especially higher users—could see little change or even pay more.
Why do I pay a standing charge at all?
It contributes to fixed costs such as maintaining the energy networks, metering, and other charges that don’t depend on how much energy you use.
Can I get a tariff with no standing charge?
Some tariffs advertise low or zero standing charges, but often have higher unit rates or specific conditions. A whole-of-market comparison helps you assess the true annual cost.
What information do I need for the best estimate?
Your postcode and annual usage in kWh (electricity and gas if you have it). If you don’t know your usage, a rough estimate is still useful for comparison.
Does switching affect my supply?
No—switching supplier doesn’t interrupt your gas or electricity supply. The pipes and wires stay the same; only the billing supplier changes.
