Electricity Price per kWh in the UK: Tips to Reduce Your Costs
Electricity costs are a significant part of household and business expenses in the UK, and understanding how much you pay per kilowatt-hour (kWh) is the first step to managing your bills effectively. With prices fluctuating due to regional differences, tariff types, and market conditions, many people wonder how they can calculate their energy costs and find ways to save.
In this guide, we’ll break down the current price of electricity per kWh in the UK, explain how your consumption affects your average electric bill, and offer practical tips to save energy. Whether you’re looking to switch tariffs, monitor your usage, or explore innovative solutions like portable power stations, this article will help you take control of your electricity costs and make informed decisions.
Current Electricity Prices per kWh in the UK
As of mid-2025, the average electricity price per kWh in the UK is around 25.73p for most households. In addition to the per-unit cost, households also pay a daily standing charge of about 51.57p, which covers the cost of maintaining the electricity supply and related services. These charges apply regardless of how much electricity is actually used.
Electricity costs can vary depending on your region and the type of tariff you are on. For example, households in London may pay slightly less per kWh than the national average, while northern regions may see marginally higher rates. Payment methods also affect prices: direct debit customers typically benefit from lower rates compared to prepayment meters.
For businesses, UK business electricity prices per kWh tend to be more variable. Rates depend heavily on consumption level, meter type, contract terms, and negotiated energy deals—meaning commercial users often pay different prices compared to domestic households.
To put it into perspective, a household using 3,000 kWh per year at 25.73p per kWh would spend around £772 on electricity units. Adding the standing charge for 365 days (about £188) brings the total annual electricity cost close to £960. Actual bills will vary based on usage, tariff, and regional differences.
You can compare this with the average electric bill in the UK, which helps you understand whether your household is spending above or below typical levels. Linking your usage with current per-kWh prices makes it easier to estimate your annual costs and identify areas where you might reduce consumption. If you want to work out your own monthly or yearly electricity spend, you can easily use a method to calculate electricity bill estimates by multiplying your total kWh usage by your tariff rate and adding the daily standing charge.
What Determines Electricity Prices in the UK
Electricity prices in the UK are influenced by a mix of market, regulatory, and consumption factors. The Energy Price Cap, set by Ofgem, plays a central role in determining how much households pay per kilowatt-hour. This cap sets a maximum price that energy suppliers can charge for standard variable tariffs, ensuring that prices remain fair for the average consumer.
Several key elements feed into the overall cost:
Wholesale Energy Costs – The price suppliers pay for electricity on the wholesale market fluctuates with supply and demand. Factors such as international energy markets, fuel costs, and geopolitical events can all impact these rates.
Network and Infrastructure Costs – Maintaining and upgrading the national grid, including transmission and distribution networks, is reflected in the standing charge portion of electricity bills.
Government Levies and Taxes – Policies aimed at reducing carbon emissions, funding renewable energy initiatives, or supporting vulnerable households are included in the final electricity price.
Regional Differences – Electricity costs vary slightly across the UK due to regional network costs and local supply conditions.
Consumption Patterns – How much energy a household or business uses affects total bills. The Energy Price Cap is based on typical domestic consumption values, meaning higher or lower usage will result in bills above or below the capped estimate.
Understanding these factors can help you make informed decisions about energy use, tariff choices, and ways to reduce costs.
Tips to Reduce Your Electricity Costs
Cutting your electricity bill isn’t just about using less energy — smart energy management and storage can make a real difference. Here are some practical tips:
1. Portable Power Stations for Managing Peak Costs
For homes that need reliable, mobile backup during UK winter outages—or that want to manage high evening tariffs, where time-of-use billing applies—a portable power station offers a practical, easy-to-deploy option.
The EcoFlow DELTA 3 Max Plus Portable Power Station (2048Wh) serves as a household core backup by delivering 3,000 W continuous output (up to 6,000 W surge), so it can keep your fridge, boiler timer and broadband running together during an outage. Its <10 ms pro-grade UPS auto-switch then steps in to prevent interruptions to online work or streaming, while industry-first full-tab LFP cells and a smart BMS ensure safer operation and a longer service life—reducing the risk and cost of early battery replacement.

By contrast, for larger homes or multi-day outages, the EcoFlow DELTA Pro 3 Portable Power Station + Smart Extra Battery bundle steps up the scale, combining higher capacity with a design built for frequent, long-term use and rated for up to 4,000 cycles to 80% capacity. With 4,000 W of continuous AC output and up to 8,000 W surge power, it can run heavy appliances while supporting whole-house load-shifting, including EV charging in many setups. Dual solar input of up to 2,600 W allows faster daytime replenishment where solar is available, and its modular design makes it straightforward to size the system for longer outages or higher household demand.
2. Adopt Energy-Saving Habits
Beyond equipment upgrades, many households overlook simple ways to save energy in everyday life.
Replace incandescent or halogen bulbs with LEDs and use lighting only where needed.
Set heating one degree lower, use a programmable thermostat or TRVs (thermostatic radiator valves) and avoid overheating rooms you’re not using.
Run washing machines and dishwashers on full loads and lower-temperature cycles; boil only the water you need in the kettle.
Draught-proof doors and windows and dry clothes outside or on a radiator airer when possible to reduce tumble-dryer use.
3. Reduce Standby Power Consumption
Identify common vampire loads (TVs, set-top boxes, games consoles, phone chargers) and switch them off at the socket when idle.
Use switched extension leads or smart plugs to cut power to clusters of devices at once.
Keep always-on kit that must remain live (e.g. broadband router) on a dedicated circuit or smart plug, so other devices are easy to isolate.
4. Monitor Usage with a Smart Meter
Install a SMETS-compatible smart meter or use your supplier’s app to view near-real-time consumption and cost data.
Check daily/weekly trends to spot spikes, then test suspect appliances (switch one off at a time) to find the culprits.
Combine smart-meter insight with a couple of smart plugs that report kWh for appliance-level measurements — this gives quick, actionable data.
Conclusion
Keeping an eye on how you use electricity and making a few smart changes can really add up. Whether it’s switching to energy-efficient lighting, unplugging unused devices, or using solar-powered storage like the EcoFlow DELTA series, every step helps lower your bills. Understanding the price of electricity per kWh in the UK and managing your usage wisely can save you money while making your home more self-sufficient and eco-friendlier.
FAQs
How much does 1 kWh of electricity cost in the UK?
As of 2025, the average price of 1 kWh of electricity in the UK is around 25–26 pence, based on the current Ofgem price cap. However, the exact rate you pay can vary depending on your supplier, tariff type, region, and whether you use a standard variable tariff or a fixed contract. Prepayment customers and those living in higher-cost regions may pay slightly more. Standing charges also influence your total bill, so your overall electricity costs depend not only on the price per kWh but also on how much energy your household consumes each day.
Is 40 kWh per day a lot in the UK?
Yes—using 40 kWh per day is considered high for a typical UK household. Most homes consume around 8–12 kWh daily, depending on property size, heating type, and appliance use.
