Understanding cheap gas and electricity prices

UK domestic energy bills are mainly driven by two pricing elements on your tariff:

  • Unit rate measured in pence per kWh, the price you pay for the energy you use.
  • Standing charge a daily fixed charge that covers the cost of supplying your property, regardless of usage.

The cheapest plan for you depends on how much energy you use and when you use it, your region, your meter type, and whether you pay by direct debit, on receipt of bill, or via prepayment. Ofgem sets a price cap for standard variable tariffs, which limits default tariff rates but does not guarantee the lowest possible price. Fixed deals and specialist tariffs may offer better value depending on your circumstances.

To find genuinely cheap gas and electric deals, compare the total annual cost and consider your usage pattern rather than only chasing the lowest unit rate or standing charge in isolation.

Types of domestic energy tariffs

Fixed rate tariffs

Lock your unit rate and standing charge for 12 to 24 months. Helpful for budgeting. Early exit fees may apply if you switch before the end date.

Variable rate tariffs

Prices can go up or down in line with wholesale and market changes, and are subject to the Ofgem price cap where applicable. Usually no exit fees.

Dual fuel deals

Get gas and electricity from the same supplier. This can simplify billing and sometimes includes a dual fuel discount.

Smart meter time of use

Tariffs such as Economy 7, Economy 10, or EV charging plans offer cheaper off peak rates for overnight usage if you can shift consumption.

Prepayment tariffs

Pay as you go using a key, card, or smart top up. Useful for budgeting, but unit rates and standing charges can be higher than direct debit options.

Green energy tariffs

Support renewable generation with 100 percent renewable electricity or carbon offset gas. Prices can be competitive while reducing your footprint.

How to get the cheapest gas and electric for your home

  • Use kWh from a recent bill for the most accurate comparison. If new to a property, we can estimate from the home size and occupancy.
  • Consider direct debit many suppliers offer lower prices for monthly direct debit compared to payment on receipt of bill.
  • Check exit fees and end dates fixed deals may have charges if you leave early. You can switch within the last 49 days of a fixed term without exit fees.
  • Install a smart meter unlocks access to time of use tariffs and more accurate billing. Availability depends on supplier and location.
  • Match tariffs to your lifestyle off peak users may benefit from Economy 7 or EV tariffs. Home workers may prefer a low daytime rate.
  • Improve efficiency draught proofing, insulation, LEDs, and smart heating controls can reduce your kWh consumption before you even switch.

Moving home or renting

When you move in, you will usually be placed on a deemed or default tariff with the existing supplier at the property. Submit opening meter readings and compare tariffs right away to avoid paying more than you need to. Tenants can usually switch supplier unless the tenancy agreement explicitly states otherwise and the landlord is the bill payer.

Cheap gas and electric FAQs

Will my energy supply be interrupted when I switch?

No. Switching is a seamless administrative process overseen by industry rules. Your gas and electricity keep flowing throughout.

How long does it take to switch?

Most switches complete in about 5 working days after cooling off, though timings can vary. You will receive confirmation and final bills from your old supplier.

Do I need a smart meter to get cheap tariffs?

Not always. Fixed and variable deals are available without a smart meter, but some of the cheapest time of use and EV tariffs require one.

What information do I need to compare prices?

Your postcode, current supplier and tariff, meter type, and annual usage in kWh if possible. A recent bill contains all of this.

Are there exit fees?

Some fixed tariffs have exit fees if you switch early. You can leave a fixed deal fee free in the last 49 days of the contract.

Can I switch if I am on a prepayment meter or in debt?

Prepayment customers can often switch. There are extra rules if you owe money. Check your eligibility before starting a switch.
