In this guide, we'll walk you through the process, answer your burning questions, and empower you to make the best choice for your energy needs.

What it means to change your energy supplier.

Switching energy suppliers means choosing a different company to provide your electricity, gas or both.

Think of it as a bit like changing your phone or internet contract – you're looking for a better deal, better service, or maybe even an environmentally-conscious option. And since energy prices fluctuate, regularly reviewing your current energy tariff can help you get the best deal.

What are the common reasons for changing energy suppliers?

People may switch energy providers for many different reasons, such as:

Cost savings.

Switching could unlock significant savings on your energy costs.

Leaf.

Greener options.

Make a positive impact on the planet by choosing a supplier that offers renewable energy tariffs.

Customer service that cares.

Tired of long wait times and unhelpful customer support? Get an energy supplier that has great customer service.

Tariff flexibility.

Find a tariff that perfectly matches your normal energy use and lifestyle. This could be a fixed tariff for a year or a tariff designed for electric vehicle chargers.

What are the key considerations before changing energy suppliers?

Before switching, check for exit fees and your contract terms such as your contract end date. 

Check your current energy use, and have your recent energy bills, current tariff information, accurate meter readings and your current supplier’s details to hand.

How much could you save by switching energy supplier?

This is the burning question for most of us. While we can't promise a specific number because it varies person to person, a change of energy supplier could unlock savings on your annual energy costs.

Your old tariff may have been great at the time, but the unit rates and standing charges might not be competitive now. Since energy prices are constantly going up and down due to the price cap, reviewing your energy deal every 3-6 months could help ensure you're not paying over the odds.

To truly understand your potential savings, you'll need to look beyond the headline price and compare the finer details, including:

  • Unit rate: The cost for each kilowatt hour (kWh) of energy you use.

  • Standing charge: The fixed daily charge that covers the cost of keeping your home connected to the energy network, even if you don't use any energy.

  • Tariff type: Whether it's a fixed rate (where your unit price stays the same for a set period) or a variable rate (which can go up or down).

  • Exit fees: Does your current contract have a fee for leaving early? If so, you'll need to add up whether the savings outweigh that cost.

Choosing the best energy supplier to switch to.

Before you make the switch, there’s a few things you should look into first.

  • Tariff types: Understand the different tariff options available (fixed, variable, dual-fuel, green energy), their pros and cons, and if there’s any exit fees. Try and forecast your annual cost too.

  • Customer service: Look for suppliers with excellent customer service ratings, and Trustpilot scores.

  • Renewable energy options: Looking to cut your carbon footprint? Then look for a supplier offering renewable electricity tariffs.

  • Price caps: Be aware of the energy price cap and how it could affect the tariff you want to switch to.

How to estimate your energy use for a new deal.

You've probably noticed that every good energy quote tool asks for your annual energy use. This is because it’s the only way to get an accurate quote. The simplest and most reliable way to figure out your estimated use is to look at your most recent annual energy statement or bill.

If you can't find your bills, you can always use national averages, however, this will only give you a rough estimate. Using your actual kilowatt-hour (kWh) data is the only way to ensure the quoted price is close to the price you'll actually pay.

How to get the most accurate energy quote.

Getting a quote that reflects your actual energy use is key to making the right choice. Follow our simple checklist to help make the process more straightforward.

1

Have your data ready.

Have your annual kilowatt-hour (kWh) use for electricity and/or gas (if you're switching both).

2

Provide an accurate meter reading.

When you’re asked for your most recent meter readings, provide them as soon as you can. Current readings are essential for the final bill from your old supplier and the opening read for your new one.

3

Know your current tariff details.

When comparing, check the unit rates, standing charges, and end date of your existing contract.

4

Forecast your annual cost.

Use a reliable comparison tool that lets you plug in your annual kWh use to create a forecast of your total annual cost. This overall figure, rather than just the unit rate, is the best way to judge which deal is cheapest for your home.

The switching process explained.

When you switch suppliers, the process is usually broken down into four steps.

1
