Ofgem standing charge cap proposal (2026): estimated savings
A practical guide to what a standing charge cap could mean for your electricity and gas bills in 2026—who’s most likely to benefit, realistic examples, and what you can do now.
- See where standing charges sit on your bill and why they vary by region and payment method
- Estimate the size of savings under different cap levels (with clear assumptions)
- Check if switching (or a different tariff type) could beat any future cap
Estimates only. Any Ofgem changes are proposals until confirmed. Your standing charge depends on region, meter type and payment method.
Fast answer: could a standing charge cap save you money in 2026?
Potentially, yes—but only if the cap is below your current standing charge and your tariff doesn’t increase unit rates to compensate. Standing charges are paid every day you’re connected, so a cap can help most for homes with low energy use or where standing charges are high in their region.
What you might save
If your standing charge dropped by 10p/day, that’s roughly £36.50 per fuel per year (10p × 365). For dual fuel, that’s about £73/year—before any changes to unit rates.
Who benefits most
Low users (small flats, single occupants), households with long periods away, and anyone in an area with above-average standing charges.
Main caveat
Suppliers could respond by shifting costs into the unit rate. If that happens, high-usage homes may save less—or even pay more overall.
Important: Ofgem has discussed options around standing charges, including reforms and caps, but details and timing can change. This page explains how to estimate possible outcomes and what to do in the meantime.
How a standing charge cap could affect your bill
Your energy bill is usually made up of:
- Standing charge (p/day)
- A fixed daily amount covering things like metering, billing, network costs and policy costs. It can differ by region, payment method (e.g. direct debit vs prepayment), and sometimes meter type.
- Unit rate (p/kWh)
- What you pay for each unit of energy used. If standing charges are reduced, suppliers could adjust unit rates to keep overall revenue similar.
A simple savings formula you can use
Estimated annual saving ˜ (Your current standing charge - Proposed cap) × 365
Example: current 55p/day capped at 45p/day ? 10p/day saving ? about £36.50/year for that fuel.
Reality check: your total bill depends on both standing charges and unit rates. The cap helps most when (1) your standing charge is currently above the cap and (2) unit rates don’t rise enough to cancel it out.
Two realistic 2026 scenarios (with numbers)
These are illustrative examples to help you understand the maths. Standing charges and unit rates vary by region and tariff. We show the assumptions clearly so you can adapt them.
Scenario A: low-use flat (electricity only)
- Usage: 1,600 kWh/year
- Current standing charge: 60p/day
- Proposed cap (illustration): 45p/day
- Unit rate change: +0.5p/kWh (possible supplier response)
Standing charge saving: (0.60-0.45)×365 ˜ £54.75
Unit rate increase cost: 1,600×£0.005 ˜ £8.00
Net estimated change: ~£46.75/year lower
Scenario B: family home (dual fuel, higher use)
- Electricity usage: 3,500 kWh/year
- Gas usage: 12,000 kWh/year
- Current standing charges: 55p/day elec, 32p/day gas
- Illustrative caps: 45p/day elec, 27p/day gas
- Unit rate change: +0.8p/kWh (elec), +0.15p/kWh (gas)
Standing charge saving: [(0.55-0.45)+(0.32-0.27)]×365 ˜ £54.75
Unit rate increase cost: (3,500×£0.008) + (12,000×£0.0015) ˜ £46.00
Net estimated change: ~£8.75/year lower
Takeaway: a cap tends to help low users more, because standing charges are a bigger part of their total bill. For high usage, any shift into unit rates matters more.
Check your best available tariff
If standing charges fall in 2026, prices may still vary by supplier and tariff. Compare now to see what you could pay based on your postcode and preferences.
Tip: When comparing, look at the annual cost (standing charge + unit rate for your usage), not just the standing charge alone.
What to gather (2 minutes)
- Your latest bill (or app screenshot) showing unit rate and standing charge
- Payment method (direct debit / receipt of bill / prepayment)
- Meter type (smart, credit, prepay; and whether you have Economy 7)
- Rough annual usage in kWh (if available)
Compare outcomes: cap vs switching vs doing nothing
A standing charge cap (if introduced) would change one part of your bill. Switching can change both standing charge and unit rate—sometimes delivering bigger savings, depending on your tariff and usage.
| Option | Best for | What could change | Key risks / watch-outs |
|---|---|---|---|
| Standing charge cap (if implemented) | Low usage; high current standing charge | Standing charge may fall up to the cap level | Unit rates could rise; timing/details may change |
| Switch tariff/supplier now | Anyone on a poor-value tariff; households willing to compare | Standing charge and unit rates can both improve | Exit fees on fixed deals; ensure tariffs fit your meter (e.g. Economy 7) |
| Do nothing (stay put) | Those in fixed deals with good rates and/or exit fees | No immediate change; you keep current tariff structure | You may miss cheaper tariffs; your rates may change at end of fix |
Quick decision checklist
- Find your standing charge (p/day) for gas and/or electricity on your bill.
- Compare it to likely cap levels (if announced). If you’re already below, a cap may not help much.
- Check your unit rate (p/kWh). A small unit rate change can outweigh standing charge savings for high usage.
- Look for exit fees if you’re on a fixed tariff.
- Confirm your meter setup: smart/prepay, Economy 7, and whether you have dual fuel.
Who it suits / who it doesn’t
More likely to suit
- Low users where standing charges make up a big share of costs
- Homes in regions with higher standing charges
- People who want predictable daily costs and compare tariffs by annual total
Less likely to suit
- High-usage households if unit rates rise materially
- Anyone with an excellent fixed deal (especially with exit fees)
- Economy 7 users on specialist tariffs (needs careful comparison)
Costs, exclusions and common pitfalls
Standing charge reform can be confusing because your bill depends on tariff structure and personal usage. These are the most common things that trip people up.
Pitfall 1: ignoring unit rates
A lower standing charge can be offset by a higher unit rate. For higher usage, even 0.5–1.0p/kWh can outweigh standing charge savings.
Pitfall 2: assuming the cap is the same everywhere
Standing charges vary by electricity distribution region and by payment method. Any cap could still leave differences—or apply differently.
Pitfall 3: fixed tariff exit fees
Switching early can cost money if your current fixed deal has exit fees. Always check your tariff terms before moving.
Prepayment meters: standing charges and unit rates can be different compared with direct debit. If you’re considering changing payment method, check eligibility and whether it’s possible with your meter type and credit situation.
Economy 7 / multi-rate meters: comparing tariffs needs care because you have day and night unit rates. A lower standing charge isn’t automatically better if the day rate is higher for your usage pattern.
What you can do now (even before any 2026 change)
- Find your current rates: standing charge (p/day) and unit rate (p/kWh) for each fuel.
- Estimate your annual cost using your typical kWh (or Ofgem/Citizens Advice guidance if you don’t have it).
- Compare whole-of-market options by total annual cost (not just one component).
- Check contract terms: exit fees, end date, and whether your tariff is fixed or variable.
FAQs
What is a standing charge?
A fixed daily cost you pay to have gas/electricity available at your property. You pay it even if you use no energy that day.
Why do standing charges vary by region in Great Britain?
Electricity standing charges often vary by distribution region because network costs differ. Gas can vary too. Payment method (direct debit vs prepayment) can also affect the standing charge and unit rate.
Would a standing charge cap apply to my tariff automatically?
If a cap is introduced, suppliers would typically update prices in line with the rules that apply to your tariff type. However, how a change is implemented can depend on the final Ofgem decision and your tariff terms—especially if you are on a fixed deal.
Could my unit rate go up if standing charges are capped?
It could. If suppliers need to recover costs, they may shift some charges into the unit rate. That’s why it’s important to compare using your estimated kWh usage, not just the daily charge.
I have a prepayment meter—does this change anything?
Prepayment prices can differ from direct debit. If reforms target certain customer groups, the impact may differ by payment method. If you can move from prepay to credit meters, check your supplier’s rules and whether you have any outstanding debt arrangements.
Does this apply in Northern Ireland?
Energy regulation differs in Northern Ireland. Ofgem’s price cap and related standing charge rules apply to Great Britain (England, Scotland and Wales). If you’re in Northern Ireland, check with the Utility Regulator and your supplier for local pricing structures.
Is it worth switching now or waiting for 2026?
If you’re on a poor-value tariff, switching can reduce your overall annual cost now. If you’re on a strong fixed deal (or would pay exit fees), it may be better to review closer to your end date. Use comparisons based on annual cost for your usage.
Where can I find my standing charge and unit rate?
They’re usually on page 1–2 of your bill (or in your supplier app) under “Your tariff” or “How we calculate your bill”. Look for p/day (standing charge) and p/kWh (unit rate).

How we assess “estimated savings”
Because a 2026 standing charge cap is a policy proposal until confirmed, we use a transparent “what-if” calculation:
- Inputs: your current standing charge (p/day), a hypothetical cap level (p/day), and your annual usage (kWh).
- Standing charge change: (current - cap) × 365.
- Unit rate sensitivity: we show how a unit rate increase (p/kWh) affects the outcome: usage × unit-rate change.
- Scope: guidance is for domestic customers in Great Britain; not business energy.
Limitations: This page cannot predict final Ofgem decisions, supplier pricing strategies, or your exact tariff availability. Regional network costs, prepayment pricing, Economy 7 structures and fixed-deal terms can materially change the result.
