Energy Price Cap October 2026 Explained: What the 4% Rise Means for You

Your energy supplier has probably emailed to say your Direct Debit is changing, and the news is talking about a '4% rise'. What matters is whether that 4% is your number — and for many homes it isn't, because this time gas and electricity moved in very different directions.

I've put this together from Ofgem's own announcement and rate tables. It's for households on a standard variable (default) tariff in England, Scotland and Wales.

From 1 October to 31 December 2026, the price cap for a typical household using gas and electricity and paying by Direct Debit is £1,723 a year, up from £1,663. That's £60 a year, or about £5 a month. Ofgem points out that prices are still 52% below the peak of the 2022 energy crisis.

If you're on a fixed tariff, none of this changes your rates until your fix ends. Ofgem says that covers around 35% of households.

Ofgem says the rise comes from higher wholesale gas prices linked to the conflict in the Middle East. At the same time, the government removed VAT from domestic electricity bills from 1 October 2026 to 31 March 2027. Put together, gas bills rise by about 8%, while electricity stays broadly stable.

So the more of your energy that comes from gas, the more of the rise you feel. Ofgem says households that don't use gas at all will see an increase of less than 1%. Without the VAT change, the typical bill would have been around £45 higher.

These are Ofgem's averages across England, Scotland and Wales for Direct Debit customers. Your exact rates depend on your region, payment method and meter, so check your supplier's letter or app.

Electricity figures no longer include VAT; gas figures include 5% VAT. Because of the VAT change, Ofgem warns that these costs can't be compared directly with earlier periods.

Typical annual levels by payment type, as published by Ofgem:

Gas central heating (most UK homes): you'll feel most of the rise, because heating is usually the biggest part of the bill. Better heating control has never mattered more — see how smart thermostat savings actually work.

All-electric homes: your bill should be broadly flat this quarter thanks to the VAT removal. Heaters on timers and plugs that measure power use help you see where the money goes.

Prepayment meters: your typical level rises by a similar 4%. The standing charge still builds up when you're not using energy, so check your balance before long cold spells.

High users: the headline number is for a 'typical' home. A large or poorly insulated house can use far more, and the rise scales with use.

1. Take a meter reading (or check your smart meter sent one) so you're billed accurately at the changeover. Our guide on how to read your smart meter shows where to look.

2. Compare fixed deals. Ofgem says fixed tariffs are available at £100 or more below the October cap. A fix isn't automatically cheaper over its whole term, so check exit fees and the length of the deal.

3. Turn your boiler's flow temperature down if you have a combi boiler — it's a free change that helps the boiler run more efficiently.

4. Stop heating empty rooms. Smart radiator valves let each room heat only when it's used — compare options in our best smart radiator valves guide.

5. Find what's costing you. A home energy monitor or a metering smart plug shows which appliances are expensive to run. Our free calculators put numbers on standby drain and thermostat changes.

The cap changes every three months. Ofgem is due to announce the level for 1 January to 31 March 2027 in late November. I'll publish a follow-up when the official figures are out, rather than guess. The VAT removal on electricity is due to run until 31 March 2027.
