October 2026 Energy Price Cap Rise: Watch Your Exit Fees

Ofgem has set the energy price cap for October 2026 at £1,723 a year for a typical dual-fuel household paying by direct debit — a rise of roughly 4% on the previous period, according to coverage of the announcement.

That figure is the headline, and the headline is the least useful part of it. The cap is not a maximum bill. It caps unit rates and standing charges for a typical usage profile, so a household that uses more than typical will pay more than £1,723, and a household that uses less will pay less. What the cap actually does is reset the benchmark against which every fixed tariff on the market is priced and sold.

What the rise actually changes for a household

If you are on a standard variable tariff, your unit rate and standing charge move with the cap from the start of the October period. Nothing is required of you. Your direct debit may be recalculated, sometimes with a lag, and any credit or debit balance carried from the summer will absorb part of the change before you feel it.

If you are on a fix, nothing happens at all in October. Your rates are what your contract says they are until it ends. The relevant date for you is not the cap change but your own contract end date — and that is the date most people cannot name without going and looking it up.

The practical consequence of a cap rise is that suppliers reprice their fixed offers around it within days. Fixes that looked expensive against the old cap can look competitive against the new one, and the market briefly fills with tariffs quoting savings "versus the October cap". Those comparisons are arithmetically true and strategically incomplete, because they compare a fixed price against a single known cap period rather than against the average of the cap periods that will run across the life of the fix.

Fixed versus variable is a question about volatility, not price

A fix is not a bet that prices will rise. It is a purchase of certainty, and certainty has a price. Historically, fixed tariffs are offered at a small premium or a small discount to the prevailing cap depending on what wholesale markets expect over the coming year. If you take a twelve-month fix at slightly below the October cap, you win only if the cap stays at or above that level for most of the year. If subsequent cap periods fall, you may end up paying more than you would have on the variable rate.

That trade-off is legitimate either way. Some households genuinely value a predictable monthly figure more than the possibility of a modest saving, particularly if the budget has no slack in it. Others can absorb variation and would rather track the market down. Neither position is wrong. What matters is knowing which one you are taking deliberately.

The variable rate has one structural advantage that is easy to forget: it carries no exit fee. You can leave a standard variable tariff at any time without penalty. That optionality is worth something, and it is precisely what you give up when you fix.

Exit fees are the term that decides the outcome

Exit fees on fixed energy tariffs are usually quoted per fuel — so a dual-fuel household with a fee of, say, £25 per fuel is looking at £50 to leave early. Some fixes carry no exit fee at all. Some carry considerably more. Many waive the fee in the final weeks of the contract, which is a detail that materially changes when you can start shopping without penalty.

This is the number that determines whether a fix is a floor or a cage. A twelve-month fix with no exit fee is close to a free option: you get price certainty and you can still leave if the market moves against you. The same tariff with a substantial per-fuel exit fee is a genuine commitment, and it needs to be priced as one. Before signing, it is worth working out how far the cap would have to fall before switching away became worthwhile once the fee is paid. If a fall of a few percent is enough to make leaving sensible, and the fee wipes out that gain, the fix is doing less for you than the headline suggests.

The corresponding trap on the other side is the rollover. When a fix ends, you are moved to the supplier's standard variable tariff unless you act. That is not automatically a bad outcome — the variable rate is capped — but it is rarely the best available rate, and it happens silently. Suppliers are required to notify you before a fix ends, and those notifications routinely arrive as one email among forty.

What to check before the October period

Before comparing anything, gather the facts about the tariff you already have. Most poor switching decisions come from comparing a new offer against a vague memory of the old one.

• Your tariff name and whether it is fixed or standard variable
• The exact end date of any fix, and whether the exit fee is waived in the final weeks
• Your unit rate in pence per kWh and your daily standing charge, for each fuel
• The exit fee, stated per fuel
• Your annual consumption in kWh — from a recent statement, not from the typical-household assumption
• Whether the tariff was a promotional rate, and what it reverts to

With those six items you can compare offers properly. Without them, you are comparing a supplier's marketing estimate for a typical household against your actual bill, which is not a comparison at all.

This is the sort of information that has no natural home. It is spread across a welcome email, a PDF statement, an in-app dashboard and a renewal notice, and it goes stale every twelve months. NYROX exists partly for this: you record the tariff type, unit rates, standing charge, contract end date and exit fee once, and the app tracks the renewal window and flags when a promotional rate is about to revert. It stays on your device, encrypted — no bank connection, no email scanning, and no ability for anyone at NYROX to read your consumption figures, which are more revealing about your household than most people assume.

The realistic timeline

If you are on a fix ending within the next few months, the useful window opens roughly seven weeks before your end date, when most suppliers let you switch without penalty. Note that date now rather than waiting for the reminder.

If you are on the variable rate, the October increase applies whether or not you act, and there is no deadline attached to reviewing fixes. Take the time to check the exit fee terms rather than the headline saving.

If you are mid-fix with an exit fee, the calculation is narrow: the saving from a new tariff over the remaining term, minus the fee. Often it does not clear. Sometimes it comfortably does. The arithmetic only works if you know the fee.

None of this is advice about what you should do — the right answer depends on your usage, your tolerance for a variable bill and what the market offers on the day you look. But every version of the decision runs through the same handful of numbers, and having them written down somewhere you trust makes the next cap announcement a ten-minute review rather than an afternoon of searching for old emails.
