Average Energy Bills UK 2026: What Households Actually Pay
The average UK household pays approximately £1,723 per year for gas and electricity combined at the Ofgem price cap for October to December 2026. But averages hide huge variation. A well-insulated 2 bed flat might pay £1,420 while a poorly insulated 5 bed detached house pays over £3,200. Here is the full breakdown.
See how much you could save
If your bills are above the averages for your property type, you are losing money through poor insulation or an inefficient heating system. Use our insulation calculator or heat pump calculator to see how much you could reduce your bills.
Current energy prices (October to December 2026)
These are the Ofgem price cap rates for 1 October to 31 December 2026, announced on 26 August 2026. The price cap changes quarterly.
Electricity: 26.32p per kWh with a daily standing charge of 54.83p. Gas: 7.97p per kWh with a daily standing charge of 29.68p. Ofgem also lowered its typical consumption values on 1 July 2026 to 2,500 kWh of electricity and 9,500 kWh of gas a year (from 2,700 and 11,500), which is why the headline £1,723 is not directly comparable with earlier typical bills.
Average energy bills by property type
| Property type | Gas bill/yr | Electricity bill/yr | Total/yr | Total/month |
|---|---|---|---|---|
| 1 bed flat | £560 | £710 | £1,270 | £106 |
| 2 bed flat | £680 | £740 | £1,420 | £118 |
| 2 bed terrace | £800 | £770 | £1,570 | £131 |
| 3 bed semi (average insulation) | £1,025 | £853 | £1,878 | £157 |
| 3 bed semi (good insulation) | £820 | £810 | £1,630 | £136 |
| 3 bed detached | £1,270 | £890 | £2,160 | £180 |
| 4 bed detached | £1,620 | £950 | £2,570 | £214 |
| 5 bed detached | £2,210 | £1,010 | £3,220 | £268 |
Based on the Ofgem price cap for October to December 2026. Gas bills calculated from EST consumption data by property type. Electricity bills use Ofgem typical consumption scaled by property size. Includes standing charges. Actual bills depend on insulation, occupancy, thermostat settings, and tariff.
Why your bill might be higher than average
Poor insulation. A poorly insulated 3 bed semi can use 40% to 50% more gas than a well-insulated one. That is the difference between an £820 and a £1,270 gas bill. Our energy bills by EPC rating guide shows what each band typically pays. Insulation is the single biggest factor in your energy bill, and many households qualify for free insulation through ECO4.
Old inefficient boiler. A 20-year-old boiler might operate at 70% to 80% efficiency versus 90% to 92% for a modern condensing boiler. That 15% to 20% efficiency gap translates directly into higher bills. A heat pump or new boiler can close this gap.
High thermostat setting. Every degree above 20C adds roughly 10% to your heating bill. The Energy Saving Trust recommends 18C to 21C for most households.
Standard variable tariff. If you have never switched supplier or tariff, you are likely on the most expensive rate. Fixed tariffs and smart tariffs can offer savings of 5% to 15%.
Average gas consumption by property type
| Property type | Gas (kWh/yr) | Insulation level | Annual gas cost |
|---|---|---|---|
| 1 bed flat | 5,500 | Average | £547 |
| 2 bed mid-terrace | 8,500 | Average | £786 |
| 3 bed semi-detached | 11,500 | Average | £1,025 |
| 3 bed semi-detached | 8,500 | Good | £786 |
| 3 bed detached | 14,000 | Average | £1,224 |
| 4 bed detached | 18,000 | Average | £1,543 |
| 5 bed detached | 24,000 | Average | £2,021 |

Average electricity consumption by property type
| Property type | Electricity (kWh/yr) | Annual electricity cost |
|---|---|---|
| 1 bed flat (1-2 people) | 1,800 | £674 |
| 2 bed terrace (2-3 people) | 2,300 | £805 |
| 3 bed semi (3-4 people) | 2,700 | £911 |
| 4 bed detached (4-5 people) | 3,500 | £1,121 |
| With electric vehicle | +2,500 | +£658 |
| With heat pump | +2,500 to 4,500 | +£658 to £1,184 |

How to reduce your energy bills
The most impactful actions, ranked by potential savings:
1. Insulate your home. Loft and cavity wall insulation can cut gas bills by 20% to 35%. Many households get it free through ECO4. This is the cheapest, most effective improvement.
2. Switch to a better tariff. Check comparison sites for fixed-rate deals below the price cap. Smart tariffs with time-of-use pricing can save 10% to 20% if you shift usage to off-peak hours.
3. Turn down your thermostat. Reducing your thermostat by 1C saves roughly £80 to £130 per year for an average home. A smart thermostat (£150 to £300) automates this and can improve your EPC by 2 to 4 points.
4. Consider a heat pump. For homes on oil, LPG, or electric heating, a heat pump can cut heating costs by 30% to 70%. The £7,500 BUS grant makes the upfront cost competitive with a new boiler. For homes on gas, savings are smaller but improve with good insulation and a smart tariff.
5. Add solar panels. A 4 kW solar system can reduce electricity bills by £450 to £750 per year. With 0% VAT until March 2027, the payback period is 8 to 12 years.
