Energy switch offers UK: compare deals against the October 2026 price cap

Budget 28 Oct 2026: gas standing charges due to go in 2027 — what it means for your bill.

Update 27 October 2026: supplier forecasts for the January cap are now £2,161–£2,192 against today's £1,723 (forecasts, not Ofgem figures). Latest forecasts.

Written by: EnergySwitch editorial team · Last reviewed: 26 October 2026

Direct answer: An energy switch offer is only worth having if it beats what you would pay under Ofgem’s price cap once you include the standing charge, the contract length and any exit fee. From 1 October to 31 December 2026 the cap is £1,723 a year for a typical dual-fuel household paying by Direct Debit (electricity 26.32p per kWh and 54.83p a day; gas 7.97p per kWh and 29.68p a day). Ofgem has not yet announced the cap for January to March 2027; it says it will do so by 25 November 2026. Any January figure you see before then is a forecast, not an official price.

This page explains how switch offers sit against the cap, what to check before you take one, and how switching works. We do not list “cheapest” deals or promise savings here: offers change daily and depend on your postcode, meter and usage.

Where the energy price cap stands now (October–December 2026)

Ofgem announced the current cap on 26 August 2026. For a typical household paying by Direct Debit for gas and electricity it is £1,723 a year, up 4% on July–September. Ofgem says the rise reflects higher wholesale gas prices.

These are averages across England, Scotland and Wales. Your own capped rates depend on your region, meter and how you pay: see price cap rates by region and the energy price cap hub. The cap limits unit rates and standing charges, not your total bill.

January 2027: not announced yet

Ofgem’s published schedule says the cap for 1 January to 31 March 2027 will be announced by 25 November 2026, and that it may publish earlier if it needs to. Until then there are no official January rates. Industry forecasts are not Ofgem figures. We track the forecasts we can check at source, each with its date, in January 2027 price cap forecasts vs Ofgem, and explain why EDF’s scenario sits at the top of the range in EDF’s January forecast explained.

What counts as an energy switch offer?

Most “offers” fall into a few types. Each has to be judged against the cap and your own usage.

Common types of household energy offer and what to check
Type of offerHow it compares with the capWhat to check
Fixed-rate tariffPrices set for the term, so a future cap rise or fall does not change themUnit rates, standing charges, length, exit fee
Standard variable (default) tariffThis is the tariff the cap applies to; prices change each quarterYour regional capped rates
Tracker or time-of-use tariffPrices follow wholesale prices or vary by time of day, not the capWhen you use energy, smart meter needs, how often rates change
Sign-up reward or cashbackA one-off extra, not a lower priceConditions for receiving it, and the tariff it comes with

Ofgem says you are not affected by cap changes if you are on a fixed rate tariff. Its August 2026 announcement said around 35% of households (about 11 million) were on fixed tariffs.

Should you take a fixed offer now or wait for January?

A fix gives you certainty; it does not guarantee you pay less than the cap over the whole term. Compare the fixed unit rates and standing charges with your current capped rates, check the exit fee in case the cap falls, and remember the January cap is not yet known. We go through the trade-offs in should I fix my energy deal this winter?

What to check before you take an offer

  1. Unit rates and standing charges together. A lower unit rate can come with a higher daily charge. See standing charges from October 2026.
  2. Exit fees. Ofgem says you may have to pay your old supplier an exit fee if you leave a fixed tariff before it ends. See how to compare energy deals with exit fees.
  3. Contract length. Know when it ends and what you move onto afterwards.
  4. Payment method. Direct Debit, standard credit and prepayment are priced differently. See prepayment vs Direct Debit.
  5. Warm Home Discount. If you are eligible for the £150 discount this winter, check the new supplier is in the scheme. See Warm Home Discount 2026/27.
  6. Debt or credit on your account. See switching when you’re in debt or in credit.
  7. Customer service. Citizens Advice scores the largest domestic suppliers out of 5. Its latest scores cover April to June 2026, with the next update due in December 2026.

How switching works

  • Your new supplier needs your postcode, current supplier and tariff, and your annual usage, all of which are on your bill.
  • Ofgem says suppliers must switch you within 5 working days. If they don’t, your new supplier must pay you £40.
  • You can cancel a switch within 14 days if you change your mind.
  • If you owe your supplier money, you can usually still switch if the debt is under 28 days old, or up to £500 on a prepayment meter.
  • Your supply is not interrupted. Only the company billing you changes.

Business energy is different

The price cap does not cover business energy contracts, and business contracts have no cooling-off period. If you are comparing for a business site, use business energy comparison instead.

Energy switch offers: FAQs

What is the energy price cap right now?

From 1 October to 31 December 2026 it is £1,723 a year for a typical dual-fuel household paying by Direct Debit. Electricity averages 26.32p per kWh with a 54.83p daily standing charge, and gas 7.97p per kWh with a 29.68p daily standing charge.

Has the January 2027 price cap been announced?

No. As of 26 October 2026 Ofgem has not announced it. It says it will do so by 25 November 2026.

Are switch offers cheaper than the price cap?

Some are and some are not. Compare the offer’s unit rates and standing charges with your regional capped rates, then add any exit fee and check the contract length.

Is a sign-up reward or cashback worth it?

Only if the tariff underneath is good value for you. A one-off reward does not change the unit rate or standing charge you pay for the rest of the contract.

Can I cancel a switch?

Yes. Ofgem says you can cancel within 14 days.

Do switch offers apply to businesses?

Household offers do not. Business energy is bought on commercial contracts and is not covered by the price cap.
