Why change energy supplier?

Staying with the same energy supplier year after year often means missing out on potential benefits. The energy market is dynamic, and new deals, improved services, and greener options emerge regularly. Switching is not just about saving money; it is about finding a supplier that truly meets your needs.

Potential savings and better deals

The most common reason people change energy supplier is to find a cheaper tariff. Energy prices fluctuate, and new customer deals can offer significant savings compared to staying on an older, less competitive tariff. Even if you are on a variable tariff, regularly comparing deals ensures you are not paying more than you need to.

Improved customer service

Poor customer service can be a major source of frustration. If you are struggling to get issues resolved, facing long wait times, or finding your current supplier unhelpful, switching can offer a fresh start. Many new suppliers prioritise customer experience, offering responsive support and transparent app experiences designed to give you peace of mind and control.

Access to greener tariffs

For those looking to reduce their environmental impact, switching suppliers can provide access to tariffs that source a higher percentage of their electricity from renewable generation. This allows you to align your energy consumption with your values, supporting a move towards a more sustainable future.

The energy switching process explained

Understanding the mechanics of switching can demystify the process. It is designed to be simple and quick, with clear protections for consumers.

How long does it take to switch?

Under Ofgem's Faster Switching rules, your new energy supplier must complete your switch within 5 working days of you agreeing to a new contract and providing all necessary information. This means you could be with a new supplier in less than a week. If your switch is delayed beyond this 5-working-day timeframe, you are entitled to £40 compensation under Ofgem's Guaranteed Standards, which your new supplier should pay automatically.

The 14-day cooling-off period

When you agree to a new energy contract, you have a 14-day cooling-off period during which you can cancel without incurring an exit fee. This period begins when you submit your switch request - the day you agree to the contract - not when your energy supply actually starts. Since the switch itself is now much faster, your supply will often begin well within this 14-day window, but the clock for cancellation started earlier.

Understanding exit fees

Some fixed-term energy tariffs include exit fees, which are charges for leaving your contract early. These fees vary between suppliers and tariffs, but they typically apply if you switch before your contract's end date and after your 14-day cooling-off period has expired. If you are on a variable tariff, there are usually no exit fees. Always check your current contract terms before initiating a switch to understand any potential charges.

Addressing common switching concerns

Many people hesitate to switch due to anxieties about complexity, hidden costs, or specific personal circumstances. However, most common concerns have clear solutions and consumer protections in place.

Switching with debt: the debt Assignment Protocol

If you have a prepayment meter and owe your current supplier money, you might still be able to switch. Under Ofgem's Debt Assignment Protocol (DAP), prepayment meter customers can switch if they owe up to £500 per fuel (electricity and gas are assessed separately). Your new supplier may agree to take on this debt as part of the switch. If you have a credit meter and owe money, your current supplier may object to your switch if the debt is older than 28 days, so it is usually best to clear any outstanding balance first.

Can renters change energy suppliers?

Yes, if you are a renter and you pay your energy bills directly to a supplier, you generally have the right to change suppliers. Your landlord cannot unreasonably prevent you from switching. However, it is always a good idea to check your tenancy agreement for any clauses regarding energy suppliers and to inform your landlord of your intention to switch. If your landlord includes energy bills in your rent, they are responsible for the supplier choice.

What if something goes wrong?

The energy switching process is regulated by Ofgem, the UK's energy regulator, which sets rules to protect consumers. If you encounter problems during your switch, such as delays, incorrect billing, or issues with compensation, you should first contact your new supplier to try and resolve the issue. If you are not satisfied with their response, you can escalate your complaint to the Energy Ombudsman, an independent body that handles unresolved disputes between consumers and energy companies. Citizens Advice also offers free, impartial advice on energy issues.

Step-by-step guide to changing your energy supplier

Switching is a straightforward process once you know the steps. Here is how to change energy supplier efficiently:

Gather your information

Before you start comparing, have your latest energy bill to hand. You will need:

• Your current supplier's name and your tariff name.
• Your annual energy consumption (in kWh) for both electricity and gas. This is usually listed on your bill or annual statement. According to Ofgem, the average UK home uses around 2,500 kWh of electricity and 9,500 kWh of gas per year.1
• Your Meter Point Administration Number (MPAN) for electricity and Meter Point Reference Number (MPRN) for gas. These unique numbers identify your supply points and are found on your bill.
• Your address and postcode.

Compare energy deals

Use an Ofgem-accredited price comparison website to compare tariffs from different suppliers. These sites will ask for your postcode, current usage, and payment preferences to provide personalised quotes. Look beyond just the unit rate; consider the standing charge, contract length, exit fees, and customer service ratings. You can also visit suppliers' websites directly to see their offerings.

Initiate the switch

Once you have chosen a new supplier and tariff, they will handle the rest of the switching process. You will provide them with your personal details and confirm your switch. Your new supplier will then contact your old supplier and manage the transfer through industry systems. You will not experience any interruption to your energy supply.

Final meter readings and bills

On your switch-in date, you will need to provide a final meter reading to your new supplier. If you have a smart meter, this is often done automatically. For manual meters, submitting an accurate reading ensures you are billed correctly by both your old and new suppliers. Your old supplier will use this reading to generate your final bill, and your new supplier will use it to start your new account.

After you switch: what to expect

The process does not end the moment you switch. A few key steps ensure a smooth transition and accurate billing.

Your first bill with the new supplier

Review your first bill from your new supplier carefully. Check that the meter readings are correct and that you are being charged at the agreed tariff rates. If anything looks incorrect, contact your new supplier's customer service team immediately. Many modern suppliers offer transparent app experiences that allow you to track your usage and bills in real-time, giving you greater control.

Getting a refund from your old supplier

If you were in credit with your previous supplier, that money does not automatically transfer. You will need to contact your previous supplier to get a refund to your bank account.

Managing your account and usage

Once settled with your new supplier, take advantage of any tools they offer to manage your energy. This could include online accounts, mobile apps, or smart meter insights. Regularly monitoring your usage can help you understand your consumption patterns and potentially identify ways to be more energy-efficient, for instance, by considering the running cost of an air source heat pump or improving your home's overall air source heat pump efficiency if you have these systems. With features like responsive customer support and transparent app experiences, managing your energy can become an empowering act of control and value.
