Ofgem Energy Switching Rights in 2026: 8 Week Rule Explained

LAST REVIEWED 2026-09-06

How long does an energy switch take under Ofgem rules?

Under Ofgem rules, a domestic energy switch should complete within 8 weeks. This is the maximum time allowed for the transfer from your old supplier to the new one. The 8-week period starts when you request the switch, and your new supplier must handle the process.

The switch process involves several steps. First, you contact a new supplier or use a comparison site. The new supplier then initiates the switch with your current supplier. Your current supplier must provide final readings and close your account. The new supplier takes over supply on the agreed date.

In practice, most switches complete faster than 8 weeks, often within 2 to 3 weeks. However, if there are complications, such as a smart meter issue or a dispute over readings, the switch may take longer. Ofgem's rules ensure that the process is not unduly delayed.

To check the progress of your switch, contact your new supplier. They must keep you informed. If the switch takes longer than 8 weeks, you may be entitled to compensation.

When switching, ensure you have your current supplier name, your account number, and your postcode. Your new supplier will handle the rest. You do not need to contact your old supplier directly.

What are your rights when switching energy suppliers?

When switching energy suppliers, you have several rights under Ofgem rules. You also have a 14-day cooling-off period after signing a new contract, during which you can cancel without penalty.

Your new supplier must provide clear information about the tariff, including the unit rates and standing charges. They must also inform you of your right to cancel. If you are switching from a supplier that has gone bust, the Supplier of Last Resort process applies, and your switch may be paused temporarily.

You have the right to a final bill from your old supplier within 6 weeks of the switch. This bill must be accurate and based on actual readings if possible. If you have a smart meter, readings are automatic.

If you encounter problems during the switch, you can complain to the Energy Ombudsman. Ofgem also has rules to protect vulnerable customers, such as the Priority Services Register. These rights ensure that switching is straightforward and fair.

What is the 8-week rule for energy switching?

The 8-week rule is a key Ofgem regulation that sets a maximum time limit for energy switches. It means that from the moment you request a switch, your new supplier must complete the transfer within 8 weeks. This rule is designed to prevent delays and ensure a smooth transition.

The 8-week period begins when you sign up with a new supplier or when you give your consent to switch. Your new supplier is responsible for managing the process. They must coordinate with your old supplier to transfer your supply.

If the switch is not completed within 8 weeks, you may be entitled to compensation. However, the 8-week rule itself does not automatically trigger compensation; it is a service standard.

In practice, most switches are completed well within 8 weeks. The average switch time is around 2 to 3 weeks. However, if you have a complex meter setup or if there is a dispute, it could take longer. Always keep records of your switch request and any correspondence.

How does the Supplier of Last Resort affect your switch?

If your energy supplier goes out of business, Ofgem's Supplier of Last Resort (SoLR) process is triggered. This means that Ofgem will appoint a new supplier to take over your supply. This process can affect an ongoing switch.

If you were in the middle of switching away from a supplier that fails, your switch may be paused. The SoLR process takes priority, and your new supplier may need to wait until the transfer is sorted. In most cases, the switch will still go ahead, but it may be delayed.

If you were switching to a supplier that fails, the switch will not complete. You will be assigned to a new supplier under the SoLR process. Your new supplier will contact you with details of your new tariff.

During the SoLR process, your energy supply is never interrupted. You will continue to receive gas and electricity. Any credit balance you have with the failed supplier will be protected. The SoLR process is designed to minimise disruption to customers.

What are the steps to switch energy supplier in 2026?

Switching energy supplier in 2026 is a straightforward process. First, compare tariffs from different suppliers. You can use comparison websites or contact suppliers directly. Look at the unit rates and standing charges to find the best deal for your usage.

Once you have chosen a new supplier, contact them to start the switch. You will need to provide your current supplier's name, your account number, and your postcode. The new supplier will then initiate the switch.

Your new supplier will handle the transfer process. They will contact your old supplier and arrange for the switch to take place. You do not need to do anything else. Your supply will continue without interruption.

After the switch, you will receive a final bill from your old supplier within 6 weeks. Your new supplier will send you a welcome letter with details of your new tariff. You have a 14-day cooling-off period to change your mind.

If you have a smart meter, it will continue to work after the switch. Your new supplier may need to update the meter's settings. In some cases, the smart meter may lose some functionality temporarily.

What should you check before switching energy supplier?

Before switching energy supplier, there are several things to check. First, check if you are on a fixed tariff. If so, you may have to pay an exit fee to leave early. Exit fees are typically around £25 per fuel, but they can be higher.

Check your current tariff's unit rates and standing charges. Compare these with the new supplier's rates. Also, check if the new tariff has any exit fees or additional charges. Look for any introductory discounts that may end after a certain period.

Check the new supplier's customer service record and financial stability. You can read reviews and check their Ofgem accreditation. Also, check if the new supplier offers any incentives, such as cashback or rewards.

Finally, check your meter readings. Provide accurate readings to your new supplier to ensure your final bill is correct. If you have a smart meter, readings are automatic. If not, take a reading on the day of the switch.

How does the energy price cap affect switching?

The energy price cap sets a maximum price that suppliers can charge for standard variable tariffs. In 2026, the cap for a typical dual fuel household is £1,663 from July to September, and £1,723 from October to December. This cap affects switching because it limits the savings you can get from switching to a standard variable tariff.

If you are on a standard variable tariff, you are already paying the cap rate. Switching to another standard variable tariff will not save you money, as they are all capped at the same level. However, you may find fixed tariffs that are cheaper than the cap.

These can be lower than the cap, but they may have exit fees. When comparing tariffs, consider the cap as a benchmark. If a fixed tariff is below the cap, it may be a good deal.

The cap is reviewed every three months. From January 2027, the cap will be announced in late November 2026. Keep an eye on the cap changes to decide when to switch.

What are the common problems when switching energy suppliers?

Common problems when switching energy suppliers include delays, incorrect final bills, and issues with smart meters. Delays can occur if your old supplier does not respond quickly or if there are technical issues. Ofgem's 8-week rule is designed to prevent excessive delays.

Incorrect final bills can happen if your old supplier uses estimated readings instead of actual ones. To avoid this, provide accurate readings on the day of the switch. If you have a smart meter, this is automatic.

Smart meter issues can arise after a switch. Some smart meters may lose their smart functionality, meaning they no longer send automatic readings. This is usually temporary, and your new supplier should fix it.

Another problem is being switched without your consent. This is known as 'slamming'. If this happens, contact your new supplier immediately. You have the right to be switched back to your original supplier.

If you have a complaint, you can contact the Energy Ombudsman. They can help resolve disputes between you and your supplier.

How to complain about an energy switch?

If you have a problem with your energy switch, you can complain to your supplier. Start by contacting their customer service team. Explain the issue and give them a chance to resolve it. Keep a record of all communications.

If your supplier does not resolve the issue within 8 weeks, you can escalate your complaint to the Energy Ombudsman. The Ombudsman is an independent body that can investigate and make a binding decision. They can order the supplier to compensate you.

When complaining, be clear about what you want. For example, you may want a correction to your bill or compensation for a delay. Provide evidence, such as emails or letters.

Ofgem also has rules about how suppliers must handle complaints. Suppliers must respond to complaints within a certain time frame. If they fail to do so, they may be in breach of their licence conditions.

Remember, you have the right to a fair and timely resolution. Do not be afraid to escalate if necessary.

What happens after you switch energy supplier?

After you switch energy supplier, your new supplier will take over your supply. You will receive a welcome letter with details of your new tariff. Your old supplier will send you a final bill within 6 weeks. This bill should be based on actual readings.

Your new supplier will also set up your account and may ask for a direct debit. You have a 14-day cooling-off period to cancel the switch if you change your mind. After this period, you are committed to the new tariff.

If you have a smart meter, it will continue to work. Your new supplier may need to update the meter's settings. In some cases, the smart meter may lose some functionality temporarily.

You should also check that your final bill is correct. If you have overpaid, your old supplier must refund the credit balance. If you owe money, you will need to pay it.

Finally, keep an eye on your new tariff's end date. When it ends, you may be moved to a standard variable tariff, which could be more expensive. Consider switching again to get a better deal.
