The overall average UK energy bill in 2019 was:
£1,289 per year
However, your electricity and gas bill will vary depending on many factors, for example, how large your house is, your home’s energy performance, and what tariff you’re on.
If you want to find out if your bill is above or below average, you need to take these differences into account.
Note the average gas and electric bill has increased since 2018 when it was £1,234 per year. Both these figures are based on government energy statistics.
Is gas or electricity more expensive?
In 2019 the average UK electricity bill was £679 per year. The average UK gas bill was £610 per year for a dual fuel household.
Per unit, electricity is significantly more expensive, at around 15p plus standing charges compared to around 4p per unit of gas. However, most households will use significantly less electricity than gas. Heating your home with gas tends to be much cheaper than electric heating.
What is the average energy bill for different house sizes?
For a typical UK household with gas and electricity the average annual energy bill would vary with house size as follows:
- 1 to 2 bedrooms: £795 per year
- 3 to 4 bedrooms: £1,163 per year
- 5 or more bedrooms: £1,639 per year
Note that if you have more people in the house for more of the day, you’d expect your bills to be slightly higher than these estimates. Similarly, a household with only one or two members who are out at work for most of the day should expect slightly lower than average bills.
The type of property you live in can also increase your bills. The typical electric bill for a 2 bed flat on the middle floor will be slightly lower than the average bill for a 2 bed detached house. This is because the flat will benefit from the heat of neighbouring properties.
You can see the full breakdown in the following tables:
| Dual Fuel | Cost | Usage (kWh) | ||
| Bedrooms | Monthly | Annually | Monthly | Annually |
| 1-2 | £66 | £795 | 817 | 9,800 |
| 3-4 | £97 | £1,163 | 1,242 | 14,900 |
| 5+ | £137 | £1,639 | 1,775 | 21,300 |
| Electricity | Cost | Usage (kWh) | ||
| Bedrooms | Monthly | Annually | Monthly | Annually |
| 1-2 | £34 | £403 | 150 | 1,800 |
| 3-4 | £49 | £590 | 242 | 2,900 |
| 5+ | £70 | £846 | 358 | 4,300 |
| Gas | Cost | Usage (kWh) | ||
| Bedrooms | Monthly | Annually | Monthly | Annually |
| 1-2 | £33 | £392 | 667 | 8000 |
| 3-4 | £49 | £572 | 1,000 | 12,000 |
| 5+ | £66 | £793 | 1,417 | 17,000 |
How does the average bill vary for different parts of the UK?
Overall, the differences in cost per unit across the UK are relatively small. Electricity bills are typically higher in Scotland and cheaper in Northern Ireland. As an example, in 2019 for the same usage of 3,600 kWh/year you would pay the following average electricity costs:
- England & Wales: £682
- Scotland: £688
For average gas usage of 13,600 kWh/year you would pay:
- England & Wales: £610
- Scotland: £605
How much higher should my electric bill be in winter?
If you pay monthly your energy bills should be flattened out across the year, so while your usage increases in winter the amount you pay should remain steady. If you are on a pay as you go plan then you should expect higher bills in winter months.
On average electricity usage is 36% higher on a winter’s day compared to an average summer day, so expect your energy bill to be 36% higher through winter, depending on the weather.
How is my average bill impacted by my energy plan?
The amount you pay can vary significantly based on the energy plan you’ve selected. According to Ofgem figures for April 2020 the average energy costs by type of tariff were:
- Standard variable tariff: £1,125 per year
- Cheapest fixed tariffs: £783 per year
Fixed tariffs can be hundreds of pounds cheaper than variable tariffs, so it’s important to shop around and switch regularly.
What should I do if my gas or electricity bill is higher than average?
There are many changes you can make to reduce your energy bill, here are just a few examples:
1. Make sure you’re on a fairly priced plan
If you haven’t switched recently you may be on a standard variable tariff, which means you will be paying more than average for every unit of energy that you use. Compare energy deals to see if there is a better deal for you.
2. Improve your energy performance & insulation
If you’re a renter, your landlord is obligated to upgrade the property to meet certain energy performance standards.
If you own the property you can look into ways to improve insulation, some changes can be done yourself, or you may be able to get a grant for these improvements.
3. Reduce your energy consumption
There are many ways to do this, from upgrading inefficient appliances, to changing your work from home habits.
