Ofgem price cap October 2026: how much will I pay?
A UK-focused guide to what the October–December 2026 Ofgem price cap could mean for your bills, with clear assumptions, examples, and how to get a personalised quote based on your home and usage.
- Understand what the price cap is (and what it isn’t) for households in Great Britain
- See how unit rates and standing charges drive your bill more than the headline “typical” figure
- Estimate your costs with two realistic scenarios and a simple step-by-step method
Estimates are illustrative only. The price cap applies to standard variable and default tariffs in Great Britain (not Northern Ireland). Your actual bill depends on your tariff, meter type, payment method, and usage.
Fast answer: what will you pay under the October 2026 price cap?
You won’t pay a single “cap amount” for October 2026. The Ofgem price cap sets maximum unit rates (p/kWh) and standing charges (p/day) for standard variable and other default tariffs in Great Britain. Your bill in October–December 2026 will mainly depend on:
Your usage (kWh)
Higher use = higher bills. The cap doesn’t limit total spend.
Your region & meter
Cap rates vary by distribution region and by meter type (credit vs prepay).
Tariff type
The cap applies to default tariffs. Fixed deals can be above or below it.
Important: Ofgem announces the cap level closer to each cap period. For October 2026, you can’t know exact cap rates until Ofgem publishes them. You can still estimate what you might pay by using the same calculation structure (standing charges + unit rates × usage), then swapping in the published cap rates when they’re released.
- If you’re on a standard variable tariff (SVT)
- Your supplier’s SVT rates must be at or below the cap for your region/meter. Your bill will still vary with your usage.
- If you’re on a fixed tariff
- The cap doesn’t usually apply. You’ll pay your agreed rates until the fix ends (check exit fees and end date).
How to estimate what you’ll pay in Oct–Dec 2026 (step-by-step)
When Ofgem publishes the October 2026 cap, you’ll see unit rates and standing charges for electricity and gas. To estimate your bill for the quarter, use this structure:
- Find your daily standing charge (electricity + gas). Multiply by days in the period.
- Find your unit rate (p/kWh). Multiply by your expected usage (kWh) for the period.
- Add standing charges + usage charges for electricity and gas.
- If you pay by Direct Debit, check whether your supplier uses a smoothing plan (monthly payments can differ from the quarterly cost).
Where to find the official rates: use Ofgem’s cap announcement and your supplier’s tariff information label / online account. Ofgem publishes regional cap levels and explains the cap structure on its website.

Two realistic scenarios (illustrative numbers)
Because October 2026 cap rates are not published yet, the scenarios below use example rates to show the method. Swap in the October 2026 rates (and your own kWh) when available.
Scenario A: small flat, low gas use
- Period: 92 days (Oct–Dec)
- Usage: 700 kWh electricity, 2,000 kWh gas
- Example rates: elec 28p/kWh + 55p/day; gas 7p/kWh + 32p/day
Estimated cost:
Electricity: (700×£0.28)=£196 + (92×£0.55)=£50.60 → £246.60
Gas: (2,000×£0.07)=£140 + (92×£0.32)=£29.44 → £169.44
Total for quarter: £416.04 (illustrative)
Scenario B: family home, higher winter demand
- Period: 92 days (Oct–Dec)
- Usage: 1,100 kWh electricity, 7,000 kWh gas
- Example rates: elec 28p/kWh + 55p/day; gas 7p/kWh + 32p/day
Estimated cost:
Electricity: (1,100×£0.28)=£308 + (92×£0.55)=£50.60 → £358.60
Gas: (7,000×£0.07)=£490 + (92×£0.32)=£29.44 → £519.44
Total for quarter: £878.04 (illustrative)
Why your Direct Debit might not match these totals: many suppliers set a monthly amount to spread costs across the year. A high-cost winter quarter can be paid partly in summer via credit on your account.

Quick check before you compare
- Know whether you have gas + electricity or electricity-only.
- Check your payment method (Direct Debit, cash/cheque, prepayment).
- If you’re on a fix, look for exit fees and the end date.
Price cap vs fixed tariff: what’s the difference in October 2026?
If you’re asking “how much will I pay?”, the key decision is often whether to stay on a capped standard variable tariff (SVT) or switch to a fixed deal. This table highlights the practical differences that affect your costs and risk.
| Feature | Capped SVT / default tariff | Fixed tariff |
|---|---|---|
| Does the Ofgem cap apply? | Yes (unit rates/standing charges limited by region & meter type) | Usually no (you pay the fixed rates agreed in your contract) |
| What changes in Oct 2026? | Supplier adjusts SVT rates to the new cap (or lower) | Nothing, unless your fix ends or your supplier changes terms after contract end |
| Budget certainty | Lower—rates can change each cap period | Higher—rates stay fixed for the term (e.g., 12–24 months) |
| Exit fees | Typically none | Common—check before switching away |
| Who it can suit | People who want flexibility and don’t want to commit | People who want predictable rates and are happy to commit for a term |
Decision checklist: it may suit you to stay on the cap if…
- You might move home soon (and want to avoid exit fees).
- You want flexibility to switch quickly if prices fall.
- You’re not sure how your usage will change (e.g., new baby, working from home).
It may suit you to consider a fix if…
- You value predictable rates over short-term flexibility.
- Your budget is tight and you’d rather reduce uncertainty.
- A fixed deal’s unit rates and standing charges compare well for your usage (not just the headline “estimated annual cost”).
Tip: compare using your kWh (from recent bills or your smart meter) rather than relying only on “typical consumption” figures. A tariff that looks good for a typical user may not suit a high- or low-usage home.
Costs, exclusions and common pitfalls (UK-specific)
These are the reasons people get caught out when trying to estimate their October 2026 bill.
1) The cap doesn’t cover every tariff
The cap is mainly for standard variable and other default tariffs. Fixed deals and some specialist tariffs can sit above or below it.
2) Your region changes the cap
Price cap levels vary by electricity distribution region (and standing charges can differ). Your postcode matters.
3) Prepayment vs credit can be different
The cap can differ by meter type and payment method (e.g., prepayment meters vs credit meters).
4) Standing charges can dominate low-usage bills
If you use relatively little energy, standing charges can make up a big chunk of your bill—especially over a full quarter.
Great Britain vs Northern Ireland: Ofgem’s price cap applies to households in England, Scotland and Wales. Northern Ireland has a different energy market and regulator arrangements.
Direct Debit smoothing: if you’re “in credit” or “in debit”, your supplier may adjust your monthly payment even if unit rates are unchanged.
Before switching: quick checks to avoid surprises
Check exit fees: fixed tariffs often charge if you leave early (fees vary by supplier and product).
Check what happens at the end of a fix: you may be moved to a default tariff (which is capped) unless you choose another deal.
Compare on unit rates + standing charges: don’t rely only on an “estimated annual cost” if your usage is unusual.

FAQs: October 2026 Ofgem price cap
When will the October 2026 price cap be announced?
Ofgem announces each cap shortly before it starts. For October–December 2026, look for Ofgem’s published decision in the lead-up to October 2026 on its energy price cap page.
Is the price cap the maximum I can pay per month?
No. It caps unit rates and standing charges on default tariffs. If you use more energy, you pay more. If you use less, you pay less.
Does the cap apply to fixed energy deals?
Usually not. Fixed deals follow the rates in your contract. If your fixed deal ends, you may move onto a default tariff that is capped (unless you choose another deal).
Why do people in different areas pay different prices under the cap?
The cap varies by region to reflect differences in network costs (among other factors). That’s why two households with the same usage can have different capped rates.
I have a prepayment meter. Does the cap work the same way?
The principle is the same (limits on unit rates and standing charges), but the cap level can differ between prepayment and credit meters. Use the Ofgem figures for your meter type.
If the cap goes down in October 2026, will my supplier automatically reduce my bill?
If you’re on a capped default tariff, your supplier should update rates in line with the new cap period (or keep them lower). Your monthly Direct Debit might not drop immediately if you’re repaying a debit balance or rebuilding credit.
What if I’m on an Economy 7 or other multi-rate electricity tariff?
Multi-rate tariffs can have day/night unit rates. The cap is more complex in these cases. Check your tariff information and Ofgem’s explanations, and compare using your actual split of day vs night usage.
Where can I get help if I can’t afford my energy bills?
Start by contacting your supplier to discuss payment plans and support. You can also get independent help from Citizens Advice, and check benefits/support information on GOV.UK.
