Why change your energy supplier?

Changing your energy supplier empowers you to demand more from your energy provider. It's a power play focused on gaining better value, service, and control over your household energy.

Seeking better value and fairer tariffs

The energy market is dynamic, with tariffs and deals constantly changing. By regularly comparing options, you can ensure you are not overpaying for your electricity and gas, potentially leading to significant energy bill savings. This isn't about scarcity; it's about making sure your money works harder for you.

Improving customer service and support

Poor customer service can be a major source of frustration. If your current supplier leaves you feeling unheard or unsupported, a switch offers the chance to find a provider committed to responsive and helpful support.

Gaining control over your energy usage

Many homeowners feel a lack of transparency over their energy supply and costs. Switching can provide access to tools and insights that give you a clearer understanding of your usage, helping you manage your energy more effectively.

The energy switching process: step by step

Changing energy supplier is a simple, regulated process designed to be hassle-free. Here's how to switch energy supplier in a few key steps:

Gather your current energy details

Before you begin, collect information about your current energy supply. This includes your existing supplier's name, your current tariff name, and ideally, your annual energy usage. Having a recent bill to hand will make this step easy.

Compare energy deals and tariffs

Use an impartial comparison service to review energy deals and tariffs from various suppliers. This allows you to compare prices, contract lengths, and customer service ratings to find a deal that best suits your household's needs.

Initiate the switch with your new supplier

Once you've chosen a new supplier and tariff, you can initiate the switch. Your new supplier will handle most of the transfer process, including notifying your old supplier.

Final meter readings and account closure

You'll need to provide a final meter reading on the day your switch completes. If you have a manual meter, you submit this reading to your new supplier, who then forwards it to your old supplier for an accurate final bill. For smart meters, your new supplier will typically handle sending the final reading automatically.

Key considerations before you switch

Understanding some key aspects of the switching process can alleviate common concerns and ensure a smooth transition.

Understanding the 14-day cooling-off period

After agreeing to a new energy contract, you have a 14-day cooling-off period during which you can cancel without penalty. This period starts from your switch-in date and is a consumer right under UK law, providing peace of mind if you change your mind.

How long does it take to switch energy suppliers?

Switching energy suppliers in Great Britain typically takes 5 working days from the moment you apply to the completion of the transfer. Ofgem's Faster Switching rules mandate this timeframe, ensuring a quick and efficient transition.

Switching with a smart meter

Having a smart meter does not prevent you from changing energy suppliers. Smart meters are designed to work across different providers, so you can switch and continue to benefit from automatic meter readings and other smart features, such as those offered by an Aclara smart meter.

Switching if you have energy debt

You can switch energy suppliers even if you owe money to your current provider, particularly if you have a prepayment meter. Under the Debt Assignment Protocol (DAP), if your debt is up to £500 per fuel (electricity and gas), your new supplier may agree to take on this debt, allowing you to switch.

What happens if your switch is delayed?

Ofgem's regulations require switches to complete within 5 working days. If your switch is delayed or mishandled beyond this timeframe, energy suppliers are required to compensate customers, typically £40 for such delays.

What information do you need to switch?

To make the switch as quick and easy as possible, have the following details ready:

Your current supplier and tariff name

This information is usually found on a recent energy bill or by logging into your current supplier's online account.

Annual energy consumption

Knowing your annual electricity and gas usage helps comparison sites provide accurate quotes. For context, the average UK home uses around 2,700 kWh of electricity per year. You can find your specific usage on your annual statement or recent bills.

Personal and property details

You'll need to provide your full address, contact information, and bank details for setting up direct debits with your new supplier.

Making the most of your new energy supplier

Once you've switched, your new supplier should offer features that enhance your energy experience.

Digital tools for energy management

Modern energy suppliers often provide digital-first apps that offer real-time insights into your energy usage and costs. This transparency empowers you to understand and manage your consumption effortlessly, helping you to make the most of agile pricing models.

Access to human customer support

The quality of customer support can significantly impact your experience. Look for suppliers that offer accessible, human customer service, providing peace of mind and support when you need it.

Understanding your new tariff and billing

Take the time to familiarise yourself with your new tariff's unit rates and standing charges. Understanding your billing cycle and how to access your statements will help you stay on top of your energy costs.
