Cheapest UK Home Energy Suppliers Right Now

Who are the cheapest UK home energy suppliers right now?

The "cheapest" UK home energy supplier changes regularly because wholesale gas and electricity prices, network charges and supplier tariffs are constantly being updated. On top of that, the Energy Price Cap set by Ofgem can change every three months, affecting what suppliers charge for standard variable tariffs.

Instead of relying on outdated price tables, we pull live tariff information from a panel of UK suppliers. This allows us to show you which suppliers are offering the lowest priced home energy plans for your specific usage and postcode at the time you run your quote.

Some of the types of suppliers and tariffs you might see when you compare include:

• Big Six & major brands – familiar household names that many UK homes already use.
• Challenger suppliers – smaller brands that often offer very competitive home energy prices.
• Fixed-rate tariffs – your unit rates are locked in for 12–24 months, protecting you from certain price rises.
• Standard variable tariffs – prices can move up or down but are protected by the Ofgem price cap.
• Green home energy tariffs – electricity backed by renewable generation certificates and, in some cases, carbon-offset gas.

Because every household uses energy differently, there is no single supplier that is cheapest for everyone. A low-use flat with an electric-only tariff will see different results compared with a large, high-use family home using dual fuel.

How to switch to a cheaper UK home energy supplier

Moving to a cheaper home energy supplier is straightforward and fully regulated. In most cases, you will not notice anything other than a smaller bill. Here is how the process works:

1. Get a personalised comparison
   Enter your postcode and a few details about your home and current tariff. We will show you a list of live deals including the cheapest suppliers for you.
2. Choose your new tariff
   Review projected annual costs, rates, contract lengths and exit fees. Pick the home energy deal that suits your budget and preferences.
3. Confirm your switch online
   Provide a few extra details (such as your full address and bank details for direct debit) so your new supplier can set up the account.
4. Let the suppliers handle the rest
   Your new provider contacts your old supplier and manages the switch. You will normally provide a meter reading on or around your switch date.
5. Start saving on your home energy bills
   Your energy will continue to be delivered through the same pipes and cables – there is no interruption to your gas or electricity supply.

If you have a smart meter, it will usually continue to work with your new supplier, although some may temporarily treat it as a traditional meter until it is fully integrated.

Our comparison clearly labels each tariff type and shows any exit fees, so you can balance certainty vs flexibility when choosing the cheapest home energy supplier for your household.

Smart meters and cheap home energy tariffs

Many of the cheapest UK home energy suppliers now encourage or require smart meters for their best value tariffs. Smart meters automatically send readings to your supplier, so your bills are based on actual usage, not estimates.

With a smart meter you may also get access to:

• Time-of-use tariffs – cheaper rates at off-peak times if you can shift some usage.
• Accurate budgeting tools – see your usage in pounds and pence on your in-home display.
• Faster switching and billing – meter reads are automated during a switch, reducing admin errors.

When you compare, simply tell us if you already have a smart meter or if you are happy to have one installed, and we will include relevant smart-enabled home energy deals in your results.

Ways to cut your home energy bills beyond switching

Switching to one of the cheapest UK home energy suppliers is one of the fastest ways to lower your bills, but there are also simple changes you can make around the home to reduce how much energy you use in the first place:

• Use a programmable thermostat and lower your heating by 1 °C.
• Fit LED bulbs in frequently used rooms.
• Only boil the water you need in the kettle.
• Turn appliances off at the plug instead of leaving them on standby.
• Wash clothes at 30 °C where possible and air-dry when you can.
• Draught-proof doors, windows and chimneys in older homes.

These small changes, combined with a cheaper home energy tariff, can add up to significant savings over the course of a year.
