What the average UK household pays in 2026
Under the Ofgem price cap that takes effect in October 2026, a typical dual-fuel home paying by direct debit faces an annual bill of around £1,738. That figure is built on Ofgem’s “typical” usage of 2,700 kWh of electricity and 11,500 kWh of gas a year. Use more than that and you pay more; the cap limits the price per unit, not your total bill.
Two numbers sit underneath it. In most regions in 2026, electricity costs roughly 24.5p per kWh and gas roughly 6.2p per kWh, plus standing charges of about 60p a day for electricity and 30p a day for gas. Those standing charges alone come to around £330 a year before you have used a single unit of energy.
Where the money actually goes
When Ofgem breaks down a typical bill, the largest slice by far is the wholesale cost of the energy itself, usually a little over a third of what you pay. The rest is made up of network costs (maintaining the pipes and wires), policy costs (funding social and environmental schemes), the supplier’s operating costs, and a small profit margin that Ofgem caps at around 2-3%. So when bills rise, it is almost always wholesale gas prices doing the moving, not supplier greed, whatever the headlines say.
- Wholesale energy: the biggest single component, and the most volatile.
- Network costs: a fixed-ish cost that largely sits in your standing charge.
- Policy and social costs: fund schemes like the Warm Home Discount and home-insulation grants.
- Supplier margin: the smallest slice, capped by Ofgem.
Heating is the bill
For a typical gas-heated home, space heating and hot water account for roughly 80% of the gas you burn, and gas is the bulk of the energy you use by volume. The Energy Saving Trust estimates that heating a home makes up well over half of the total annual energy bill. That single fact decides where the savings are: turning your attention to how you heat the house will always beat fiddling with appliances.
To put it in pounds: of an £1,738 bill, something in the region of £900-£1,000 is going on keeping the house and its water warm. Lighting and the dozens of small appliances most people worry about are a much smaller share.
What a typical day’s electricity looks like
It helps to see where the units go. At 24.5p per kWh, here is roughly what common uses cost to run:
| Use | Energy used | Rough cost |
|---|---|---|
| Boiling a full kettle | 0.1 kWh | about 2.5p |
| A 30-minute electric shower | 4.5 kWh | about £1.10 |
| One tumble-dryer cycle (vented) | 2.5 kWh | about 60p |
| An hour of oven use | 2.0 kWh | about 50p |
| Charging an electric car (40 kWh) | 40 kWh | about £9.80 at peak, or £2.80 on a 7p overnight rate |
The electric-car line is the clearest example of the single biggest lever most homes have: when you use power, not just how much. A time-of-use tariff that charges 7p overnight instead of 24.5p turns a £9.80 charge into £2.80.
Why two identical houses get different bills
Plenty of the variation between homes has nothing to do with the cap:
- How the house is heated: an old gas boiler, a heat pump and direct electric heating produce wildly different bills for the same warmth.
- Insulation: an uninsulated loft can lose around a quarter of a home’s heat, according to the Energy Saving Trust. A well-insulated home simply needs fewer units.
- Occupancy and habits: a house occupied all day, heated to 21C, costs far more than one heated to 18C for a few hours.
- Region and payment method: unit rates and standing charges vary by region, and prepayment or “on receipt of bill” customers pay more than direct-debit ones.
Where the savings really are
Because heating dominates, the things that move the bill most are, in rough order of impact: insulating what is not insulated (loft and cavity walls first, as the cheapest wins), turning the thermostat down a degree (the EST estimates this can save around £90 a year on its own), upgrading a very old heating system, and shifting flexible electricity use to a cheaper time-of-use window. Swapping every bulb for LEDs and switching off standby gadgets is worth doing, but it nibbles at the small slice, not the big one.
