Understanding cheap electricity rates

Electricity prices in the UK can vary significantly, influenced by factors like wholesale costs, network charges, and supplier overheads. Finding "cheap" electricity often means finding a tariff that aligns with your usage patterns and offers lower unit rates or standing charges.

What makes electricity cheaper?

The cost of electricity is a complex mix. Wholesale prices, which suppliers pay for the energy itself, are a major component. Other costs include maintaining the grid, environmental levies, and supplier operating expenses. Tariffs designed to encourage off-peak usage, for instance, offer lower rates when demand on the National Grid is typically lower. This helps balance supply and demand across the network.

The role of the energy price cap

Ofgem, the UK's energy regulator, sets an energy price cap that limits the maximum unit rate and standing charge suppliers can charge for standard variable tariffs. For a Direct Debit household on a Standard Variable Tariff, the electricity unit rate is 26.11p per kWh from 1 July to 30 September 2026. This cap is reviewed quarterly and influences the overall cost of electricity for millions of households.

Exploring time-of-use tariffs

Time-of-use tariffs offer different electricity rates depending on the time of day, encouraging consumers to shift their usage to off-peak periods when electricity is cheaper.

Economy 7 and Economy 10 explained

Economy 7 tariffs provide a cheaper rate for seven hours during the night, with a higher rate during the day. These tariffs were originally designed for homes with storage heaters that could charge up overnight. The exact off-peak hours can vary by supplier and region, so it is important to check with your provider for your specific schedule.

Economy 10 tariffs are similar but offer ten hours of cheaper electricity, often split into periods during the afternoon, evening, and overnight. While beneficial for those who can shift significant energy use to these times, Economy 10 tariffs are less common than Economy 7.

When is electricity cheapest in the UK?

Electricity is generally cheapest during off-peak hours, typically overnight. For Economy 7 tariffs, these seven hours occur overnight, but specific timings depend on your supplier and location. It is crucial to check with your energy provider for your exact off-peak schedule, as these times can also be affected by changes between British Summer Time (BST) and Greenwich Mean Time (GMT).

Smart meters: unlocking cheaper rates

Smart meters are essential for accessing most modern time-of-use tariffs, including many Economy 7 deals. They automatically record and send your energy readings, allowing suppliers to accurately bill you for your usage at different rates.

Older off-peak tariffs often relied on Radio Teleswitch Service (RTS) meters, which use a radio signal to switch between peak and off-peak rates. However, the RTS system is being phased out, with the signal switch-off beginning on 30 June 2025. If you have an RTS meter, your current supplier should contact you to arrange a free upgrade to a smart meter. Once upgraded, you will be able to access a wider range of tariffs.

Finding the best cheap electricity deals

Finding a cheaper electricity deal requires a proactive approach, comparing options and understanding the details of each tariff.

Comparing tariffs and suppliers

The UK energy market is competitive, and comparing tariffs from different suppliers is key to finding a better deal. Comparison websites can help you see what is available based on your postcode and estimated usage. However, always check the terms and conditions directly with the supplier before committing.

What to look for in a cheap rate electricity tariff

When comparing tariffs, consider not just the unit rate but also the daily standing charge, which is a fixed daily fee regardless of how much energy you use. For time-of-use tariffs, evaluate if the cheaper off-peak rate genuinely offsets the potentially higher peak rate, given your household's energy habits. Look for transparency in pricing and clear information about contract length and any exit fees.

Avoiding common pitfalls when switching

One common mistake is not regularly comparing tariffs; loyalty does not always pay in the energy market. Another pitfall is misunderstanding how time-of-use tariffs work or failing to adjust your energy consumption to maximise savings during off-peak hours. Sticking with outdated meters, like RTS, can also limit your tariff options. Ensure you understand the off-peak times and whether a tariff truly suits your lifestyle before switching. You can learn more about the switching process to make an informed decision.

How to switch to a cheaper electricity provider

Switching energy suppliers in the UK is a straightforward process designed to encourage competition and consumer savings.

The step-by-step switching process

1. Understand your current usage: Review past bills to get an idea of your annual or monthly electricity consumption. The average UK home uses around 2,500 kWh of electricity per year1.
2. Check your meter type: Confirm if you have a smart meter or a traditional meter, as this affects tariff eligibility. If you have a manual meter, you can still switch to Fuse on a standard tariff and are eligible for a free smart meter upgrade after switching in.
3. Compare tariffs: Use comparison tools to find deals that match your usage and meter type.
4. Initiate the switch: Once you have chosen a new supplier and tariff, they will handle most of the switching process. This typically involves contacting your old supplier and arranging the transfer.
5. Provide a meter reading: You will usually be asked for a final meter reading on the day of the switch to ensure accurate billing from both your old and new suppliers.

What happens after you switch?

After your switch is complete, your new supplier will send you a welcome pack with your tariff details and information on how to manage your account. You will start being billed at your new rates, and your old supplier will send a final bill. The physical electricity supply to your home remains uninterrupted throughout the process.

Maximising your savings with cheap electricity

Finding a cheap electricity tariff is only the first step; optimising your energy usage is crucial for long-term savings.

Adjusting your energy usage

To truly benefit from time-of-use tariffs, you need to shift high-energy activities to off-peak hours. This could include running washing machines, dishwashers, and tumble dryers overnight. If you have electric vehicle charging, scheduling it during the cheapest hours can lead to significant savings. Smart appliances and smart plugs can help automate this process, making it easier to take advantage of lower rates.

Beyond tariffs: long-term energy management

Beyond simply switching tariffs, consider long-term energy management strategies. This includes understanding your energy consumption patterns, making your home more energy-efficient, and exploring options like solar panels or battery storage to generate and store your own electricity.
