Should I Switch Energy Supplier? October 2026 Guide

Next update: when Ofgem announces the January to March 2027 price cap, due by 25 November 2026.

Should you switch energy supplier? As of 25 October 2026, yes if you are on a standard variable tariff or within the last 49 days of a fixed deal, because you can leave with no exit fee and compare fixed tariffs against the £1,723 price cap for a typical home. If your fix has more than 49 days left, only switch if the saving beats your exit fee. The timing matters this autumn: Ofgem will announce the January to March 2027 cap by 25 November 2026, and forecasts published in October put it between £1,999 (Cornwall Insight) and £2,185 (British Gas) a year for a typical dual-fuel home. Forecasts are not official, so this SwitchSquid guide gives you a simple decision tree, the exact rules on exit fees and switching times, and a reminder to re-check after 25 November.

Should I switch energy supplier? The quick decision tree

Find the line that matches your situation. You can see which tariff you are on, and when any fixed deal finishes, on your latest bill or in your supplier’s app.

1. You are on a standard variable tariff (the price cap). You can switch at any time without an exit fee. Compare fixed deals against the cap for your own usage. If a fix costs about the same as or less than the cap today, it protects you if January’s cap goes up as forecast. If every fix is dearer, staying on the cap is a reasonable choice until Ofgem’s 25 November announcement.

2. Your fixed deal finishes within 49 days. Switch now. Citizens Advice confirms you can leave a fixed tariff with no exit fee once you have 49 days or less left. If you do nothing, most suppliers move you onto their standard variable tariff when the fix finishes.

3. Your fix has 50 days or more left. Check the exit fee on your bill or in your account. Switch early only if the saving over the remaining months is bigger than the fee. Often it isn’t, so set a reminder for the date you reach the 49-day window.

4. You owe your supplier money. If the debt is more than 28 days old, you usually need to pay it off before you can switch, unless you have a prepayment meter and owe £500 or less. Our switching when you owe money guide explains the options.

5. You are moving house. You don’t switch in the usual way; you take over the supply at the new address and can then compare. Take meter readings on the day you move.

If you only want the fix-or-stay answer, our should I fix my energy deal guide goes deeper on that one question.

What does the £1,723 price cap mean for your bill?

The price cap is not a cap on your total bill. It limits the unit rates and daily standing charges a supplier can charge on a standard variable tariff. The £1,723 figure is what Ofgem calls a typical dual-fuel home paying by Direct Debit would pay over a year at the current rates. Your bill depends on how much energy you use.

Source: Ofgem, checked on 25 October 2026. Rates vary by region and payment method; our price cap by region guide has the local figures, and the price cap explainer covers how it works.

What the numbers say: to compare a fixed deal fairly, ask for a quote using your own yearly kWh, then compare it with what the same usage would cost at the rates above. If the fix is close to or below the cap, you are paying little or nothing extra for certainty.

Will energy prices go up in January 2027?

Nobody knows for certain until Ofgem publishes, which it says it will do by 25 November 2026 for the period 1 January to 31 March 2027. The forecasts published in October all point upwards. Cornwall Insight forecast £1,999 on 30 September, EDF £2,148 on 16 October, E.ON Next £2,166 on 19 October and British Gas £2,185 in an update on 15 October, all for a typical dual-fuel home. That would be roughly £23 to £39 a month more than today for a typical home.

Treat these as estimates rather than promises. Wholesale prices can move between now and the announcement, and forecasts have been wrong in both directions before. Our January 2027 forecast page tracks each forecast with its date, and when is the next price cap announcement lists the 2027 dates.

Re-check after 25 November

Whatever you decide now, put 25 November 2026 in your diary. Once Ofgem confirms the January cap:

• If you stayed on the cap: compare fixed deals again against the new rates. Fixed prices can change quickly around an announcement, so compare on the day.

• If you fixed: check your new rates against the January cap so you know where you stand. You are protected from the rise for the length of your fix.

• If your fix is due to finish in early 2027: note the date you reach the 49-day window, because you can switch from then with no exit fee.

How long does switching take, and what can go wrong?

Ofgem says suppliers must switch you within five working days, and if they don’t, the new supplier must pay you £40 automatically. You also get a 14-day cooling-off period, starting the day after you agree the contract, during which you can cancel without a fee. Your supply doesn’t go off at any point; only the name on the bill changes.

The things that most often go wrong are simple to avoid:

• No final meter reading. Take a photo of your meters on switch day so the old supplier’s final bill is accurate.

• Credit left behind. If your old account is in credit, ask for the refund. Our credit balance refund guide explains your rights.

• Direct Debit set too high. Check the new supplier’s estimate against your real usage.

Our how long does it take to switch guide walks through each day of the process.

When is switching not worth it?

Switching isn’t always the right move, and it is fine to stay put. It is usually not worth switching when your current fix is cheaper than anything on offer, when the exit fee wipes out the saving, or when the only cheaper deals need you to give up something you value, such as a smart export tariff or an electric vehicle rate. Renters can usually switch if they pay the bills directly; our switching when renting guide covers the exceptions.

Fit summary

• Switch now: you are on a standard variable tariff and a fixed deal costs the same as or less than the cap for your usage, or your fix finishes within 49 days.

• Wait for 25 November: you are on the cap and every fix you are offered is dearer than the cap today.

• Stay where you are: your current fix has months left, an exit fee and a better price than today’s deals.

• Get help first: you owe your supplier money or are struggling with bills. Contact your supplier and Citizens Advice before you switch.

• Exit fees can apply if you leave a fixed tariff with 50 or more days left.

• Not every supplier or tariff appears on every comparison service.

FAQ

Is it worth switching energy supplier now?

It is worth comparing now if you are on a standard variable tariff or your fix finishes within 49 days, because you can switch without an exit fee. Forecasts published in October suggest the cap may rise in January 2027. If no fixed deal beats the cap for your usage, waiting until Ofgem’s 25 November announcement is a reasonable choice.

Can I switch energy supplier without paying an exit fee?

Yes, if you are on a standard variable tariff, or you have 49 days or less left on a fixed deal. With 50 days or more left, your supplier may charge an exit fee. Check the amount on your bill or account before you decide.

Will my energy be cut off when I switch?

No. Your gas and electricity keep flowing through the same pipes and cables; only the company that bills you changes. Ofgem says the switch must happen within five working days.

What happens if my fixed deal finishes and I do nothing?

Most suppliers move you onto their standard variable tariff, which is limited by the price cap. You can then switch at any time without an exit fee. You may pay more than you would on a new fix, so it is worth comparing.

When will the January 2027 price cap be announced?

Ofgem says it will announce the cap for 1 January to 31 March 2027 by 25 November 2026. The following announcements are due by 23 February 2027 and 26 May 2027.

Can I change my mind after switching?

Yes. You have a 14-day cooling-off period, starting the day after you agree the new contract, and you can cancel during that time without paying a fee.

Can I switch if I have a prepayment meter?

Usually yes. If you owe up to £500 on a prepayment meter, you may still be able to switch and take the debt with you. Our prepayment switching guide covers the details.

Final decision card

If you are on a standard variable tariff or within 49 days of your fix finishing, compare fixed deals today against the £1,723 cap for your own usage, because you can move with no exit fee and switching takes no more than five working days. If nothing beats the cap, there is no harm in waiting for Ofgem’s announcement on or before 25 November 2026 and comparing again then.
