Average UK Energy Bills in 2025

What You’re Likely to Pay & How to Reduce Your Costs

Find out how much the average UK household pays for gas and electricity in 2025. Based on Ofgem’s latest price cap data. Includes monthly averages, usage by house size, and proven ways to reduce your energy bills.

Average Energy Bills in the UK in 2025

Energy prices continue to be one of the biggest concerns for UK households. With Ofgem updating the energy price cap every quarter, it can be difficult to keep track of exactly what the "average" household is paying and what that means for your own bills.

This guide breaks down 2025 cost data, explains what influences your bills and shows you practical ways to bring your monthly spending down.

Average Monthly Electricity Bill in the UK (2025)

For a medium-use household, the average monthly electricity bill in the UK in 2025 is approximately £73.41. This figure is based on Ofgem’s estimate that a typical household uses around 2,700 kWh of electricity per year, which works out to roughly 225 kWh per month.

The Ofgem price cap for electricity between 1 July and 30 September 2025 sets the unit rate at 25.73p per kWh, with a daily standing charge of 51.37p. When calculated, this results in a monthly cost of £15.52 for the standing charge and £57.89 for consumption, bringing the total to £73.41 per month.

Average Monthly Gas Bill in the UK (2025)

The average monthly gas bill for a typical UK household is around £69.72. Ofgem estimates that such a household consumes 11,500 kWh of gas per year, or 960 kWh per month.

For the same period (1 July to 30 September 2025), the price cap for gas sets the unit rate at 6.33p per kWh and a daily standing charge of 29.82p. This equates to £8.95 for the standing charge and £60.77 for consumption, totaling £69.72 per month. More details are available on Ofgem’s gas price cap page.

Average Monthly Energy Bill by House Size (2025)

Ofgem publishes guidance on typical energy usage for different household sizes, which helps estimate what an average monthly dual-fuel bill looks like in 2025.

According to, Ofgem - smaller households, such as flats or one-bedroom homes, are "Low usage".

These properties typically use around 150 kWh of electricity per month, along with 625 kWh of gas. Based on the current price cap, this results in an average monthly energy bill of approximately £102.85.

A medium-sized home, usually a two or three-bed property, falls into Ofgem’s “medium usage” category. These households consume roughly 225 kWh of electricity and 960 kWh of gas each month. Using the same capped rates, the average monthly energy cost rises to about £143.25.

Larger homes, generally four bedrooms or more fall under “high usage”. These properties typically require around 342 kWh of electricity and 1,415 kWh of gas each month. As a result, the average monthly energy bill for a high-usage household is approximately £202.28.

Why Your Own Energy Bill May Be Higher or Lower

While Ofgem calculates the national “average” energy bill using a typical medium-use household, individual bills can vary significantly depending on several real-world factors.

One of the biggest influences is your actual energy consumption. Homes that use more electricity or gas, whether due to lifestyle, property size, or inefficient appliances - will naturally see higher monthly costs, while lower-usage households may pay considerably less.

Your tariff also plays a major role. The Ofgem price cap only applies to standard variable tariffs, meaning it does not cover fixed-rate or specialist tariffs. Depending on when a fixed tariff was set, you might pay either more or less than the capped rate. For more details, see Which’s guide on energy price caps.

Where you live is another important factor. Energy distribution costs vary by region, which means standing charges and unit prices can be slightly higher or lower depending on the part of the UK you’re in. Learn more on Ofgem’s energy price cap explainer page.

Your payment method can also affect the total amount you pay. Customers who pay by Direct Debit usually benefit from lower overall costs compared to those who pay on receipt of bill or use prepayment methods.

Finally, the time of year has a major impact. Energy bills tend to rise in the winter months when households rely more heavily on heating and lighting, and they fall in summer when usage naturally drops. For this reason, even your own monthly bills can fluctuate throughout the year, regardless of your tariff.

How to Reduce Your Gas and Electricity Bills

One of the simplest ways is to switch tariffs or providers. If you are currently on a standard variable tariff, there’s a good chance you could be overpaying. Comparing deals and opting for a fixed-rate plan can lock in predictable costs and protect you from future price cap increases. You can explore current options on Ofgem’s energy price cap page.

Reducing your energy consumption is another effective strategy. Even small changes can make a noticeable difference. Simple actions include using LED bulbs, fully switching off devices instead of leaving them on standby, lowering your boiler flow temperature, and improving home insulation to retain heat more efficiently.

For long-term savings, consider installing solar panels. Solar energy can significantly reduce electricity bills over time, especially when paired with battery storage systems, which allow you to store excess power for use when needed. You can see available schemes and government support on the UK Government solar panel grants page.

Your payment method also matters. Paying your energy bills by Direct Debit is usually the cheapest option under Ofgem’s price cap framework, helping you avoid additional charges that can occur with other payment methods.

Finally, staying informed about the energy price cap is important because it changes quarterly. Keeping an eye on Ofgem updates can help you plan your energy use, anticipate price changes, and identify opportunities to switch deals or make efficiency improvements.

Final Thoughts: Navigating Your Energy Costs in 2025

In 2025, the average UK dual-fuel household can expect to pay around £143 per month for energy. However, your actual costs may be higher or lower depending on factors like your home size, energy usage, tariff choice, and location.

The good news is that there are concrete steps you can take to manage these costs. From switching to a better tariff, reducing energy consumption, and investing in home efficiency to exploring solar panel schemes, you have the tools to take control of your bills. Staying informed about the Ofgem price cap and monitoring your household usage can help you anticipate changes and make smarter decisions.

Ultimately, while energy costs may fluctuate throughout the year, being proactive and strategic can mean lower bills, greater predictability, and even long-term savings. By understanding your energy consumption and using the available support schemes, you can stay one step ahead and make your home more energy-efficient and wallet-friendly in 2025 and beyond.
