How much is 1 kWh of electricity in the UK? 26.11p Under the cap

The average unit rate for electricity under the Ofgem Price Cap for 1 July to 30 September 2026 is 26.11p per kWh for customers paying by Direct Debit. This figure, set by the energy regulator Ofgem, provides a benchmark for what households on standard variable tariffs can expect to pay for their electricity usage. However, the exact cost you pay per kilowatt-hour (kWh) can vary based on your region, payment method, and the specific tariff you are on.

Understanding the components of your electricity bill, including unit rates and standing charges, is key to managing your energy costs. Fuse Energy offers clear visibility of your energy usage through its app, helping you to understand and manage your costs per kWh. Click here to get started.

Understanding your electricity bill: unit rates and standing charges

Your electricity bill isn't just about how much energy you consume; it's a combination of different charges. Understanding these components is the first step towards taking control of your energy costs.

What is a kilowatt-hour (kWh)?

A kilowatt-hour (kWh) is the standard unit of measurement for electricity consumption. It represents the amount of energy used by a 1,000-watt (1 kilowatt) appliance running for one hour. For example, a 100-watt light Bulb left on for 10 hours would consume 1 kWh of electricity. Energy suppliers charge you based on the total kWh you use.

The electricity unit rate explained

The unit rate is the price you pay for each kWh of electricity you consume. This is the core cost that fluctuates with market conditions and is subject to the energy price cap for standard variable tariffs. For the period of 1 July to 30 September 2026, the average electricity unit rate under the price cap is 26.11p per kWh for Direct Debit customers. This rate covers the wholesale cost of electricity, network charges, operating costs, and environmental levies.

Daily standing charges: what you pay just to be connected

Beyond the unit rate, your electricity bill includes a daily standing charge. This is a fixed daily fee you pay regardless of how much electricity you use, covering the cost of maintaining the energy network and other fixed operational expenses. Ofgem's energy price cap also sets a maximum daily standing charge for electricity. For Direct Debit customers, this averages 57.19p per day from 1 July to 30 September 2026. Standing charges can vary slightly depending on your region.

The energy price cap and its impact on UK electricity prices

The energy price cap is a crucial mechanism designed to protect consumers from excessive energy costs. You can find a more detailed energy price cap explained in our other articles.

How Ofgem sets the price cap

Ofgem, the UK's energy regulator, sets the energy price cap every three months. This cap limits the maximum amount suppliers can charge for each unit of gas and electricity, as well as the daily standing charge, for customers on standard variable tariffs. The calculation considers various factors, primarily wholesale energy prices, which account for a significant portion of a typical bill.

What the price cap covers (and what it doesn't)

The price cap applies to standard variable tariffs (SVTs), which most households are on if they haven't actively chosen a fixed deal or if their fixed deal has ended. It caps the unit rate and standing charge, but it does not cap your total energy bill. The more energy you use, the higher your bill will be, even under the cap. Fixed tariffs are not covered by the price cap.

Historical trends and future forecasts

The energy price cap is reviewed and adjusted quarterly (in January, April, July, and October), meaning prices can fluctuate seasonally. For the period of 1 July to 30 September 2026, the cap saw an increase of 13%, primarily driven by higher wholesale gas prices. Ofgem announces the next cap levels on specific dates: 26 August 2026 (for 1 October to 31 December 2026), 25 November 2026 (for 1 January to 31 March 2027), and 23 February 2027 (for 1 April to 30 June 2027). Prices remain well below the 2022 peak, when the government capped bills at £2,500.

Factors influencing the price per kWh

Several interconnected factors contribute to the price you pay for each kWh of electricity.

Wholesale energy costs

The largest component of your electricity bill is the wholesale cost of energy - what suppliers pay for gas and electricity on the open market. These costs are volatile and can be influenced by global events, supply and demand, and geopolitical factors. Fluctuations in wholesale prices are the primary driver behind changes in the energy price cap.

Network charges and operating costs

Network charges cover the costs of building, maintaining, and upgrading the infrastructure that delivers electricity to your home, including power lines and substations. Operating costs encompass everything from customer service and billing to metering and debt management. These costs are factored into both the unit rate and the standing charge.

Environmental levies and VAT

Environmental levies are charges designed to fund government initiatives aimed at reducing carbon emissions and promoting renewable energy. These policy costs are included in your bill. All tariff rates (unit rates and standing charges) are quoted inclusive of VAT at 5%.

Comparing electricity tariffs and finding the best deal

Understanding your options and actively comparing tariffs can lead to significant savings on your electricity bill.

Fixed vs variable tariffs

Energy tariffs typically fall into two main categories:

• Fixed tariffs: Your unit rate and standing charge are locked in for a set period, usually between 12 and 18 months. This offers predictability but might come with exit fees if you switch before the contract ends.
• Variable tariffs: Your unit rate and standing charge can change based on market conditions. These are usually subject to the energy price cap. While they offer flexibility, prices can go up or down. For more information, read our article on fixed vs variable energy tariffs.

Smart meters and tariff eligibility

Smart meters automatically send your electricity and gas readings to your supplier, eliminating estimated bills and the need for manual submissions. They also unlock eligibility for a wider range of tariffs, including time-of-use or dual-rate tariffs, which can offer cheaper electricity during off-peak periods. Many suppliers offer smart meter installation for free.

How to compare suppliers effectively

To find the best deal, compare tariffs from different suppliers, including Fuse Energy. Look beyond just the unit rate; consider the standing charge, contract length, exit fees, and customer service quality. Fuse's digital-first app provides clear visibility of your energy usage, helping you understand and manage your costs per kWh. Fuse also offers 24/7 human customer support to clarify billing and tariff queries. For a deeper dive, check out our guide on understanding your energy bill.

Strategies to manage and reduce your electricity costs

Taking an active role in managing your energy consumption can help you reduce your electricity bill.

Understanding your typical consumption

The average UK home uses around 2,500 kWh of electricity per year (Ofgem's medium typical domestic consumption value, effective 1 July 2026)1. Knowing your own typical consumption is key to understanding your bill and identifying areas for reduction. Your energy bill or supplier's app (like Fuse's) can provide insights into your usage patterns.

Optimising appliance usage

Simple changes in how you use your appliances can make a difference. Consider running high-energy appliances like washing machines or dishwashers during off-peak hours if you are on a time-of-use tariff. Unplug devices when not in use to avoid 'phantom load' and ensure your appliances are running efficiently.

The role of smart technology in cost control

Smart meters and smart home devices offer greater control over your energy use. Smart meters provide real-time data, allowing you to see how much energy you're using and when. This information empowers you to make informed decisions about your consumption, moving beyond a scarcity mindset towards making informed choices for more energy.

Managing your energy bills should be clear and easy to understand. Fuse Energy focuses on straightforward pricing, so you can see exactly what you're paying without unnecessary complexity. If you have a smart meter, you can view detailed usage data through the app or website, helping you understand how you can lower your bills. If you don't have a smart meter, Fuse Energy can upgrade your non-smart meter, completely for free. This can make it easier to track spending and make informed decisions about your energy use.
