Types of domestic energy tariffs

Fixed-rate tariffs

Your unit rates and standing charge are fixed for a set term (e.g. 12–24 months). Your monthly cost may still vary with usage. Early exit fees can apply if you leave before the end of the term.

Standard variable tariffs (SVT)

Rates can move up or down. For most households in Great Britain, the Ofgem price cap limits the maximum a supplier can charge on default SVTs, and it is reviewed quarterly.

Time-of-use tariffs

Pay different rates at different times (e.g. Economy 7 or smart time-of-use). Cheaper off-peak rates can benefit homes that can shift usage to night-time or off-peak periods.

Prepayment (PAYG)

Top up a key/card or smart meter in advance. Useful for budgeting, though unit rates and standing charges can differ from credit meters.

Green & renewable tariffs

Electricity backed by Renewable Energy Guarantees of Origin (REGO). Some suppliers also offer carbon-offset gas. Terms and sources vary by supplier.

Dual fuel

Get your gas and electricity from the same supplier. It’s convenient and may offer incentives, but always compare against single-fuel options.

Understanding your bill: standing charge and unit rates

Your energy bill has two main parts:

  • Standing charge: A daily fixed amount (pence per day) to cover the cost of supplying your home, regardless of usage.
  • Unit rate: The price you pay for each kWh of electricity or gas you use.

Estimated annual cost is based on your expected usage multiplied by unit rates, plus standing charges. Actual costs vary with how much energy you use. When comparing tariffs, check:

  • Unit rates and standing charge for each fuel
  • Contract length and any exit fees
  • Payment method discounts (e.g. direct debit)
  • Eligibility and regional pricing differences

Smart meters and time-of-use pricing

Smart meters automatically send readings to your supplier, helping you track usage and avoid estimated bills. They can unlock time-of-use tariffs with cheaper off-peak rates. You can usually switch supplier with a smart meter — if your new supplier can’t support your meter model in smart mode, it will function like a traditional meter until it’s upgraded.

What you need to compare energy deals

  • Your postcode
  • A recent bill with your annual kWh usage or monthly spend
  • Meter type (standard, Economy 7/10, smart, prepayment)
  • Current supplier and tariff name (if applicable)
  • Preferred payment method (monthly direct debit, payment on receipt, prepayment)

Easy ways to lower your home energy costs

  • Use your accurate kWh usage when comparing to get realistic annual cost estimates.
  • Consider a fixed tariff for budgeting, or remain on a variable tariff if you prefer flexibility.
  • If you have a smart meter, explore off-peak time-of-use tariffs and shift usage to cheaper hours where possible.
  • Lower your thermostat by 1°C, draught-proof doors and windows, and upgrade to LED lighting.
  • Wash at 30°C and run full loads; avoid standby by switching devices off.

Financial support and priority services

If you’re struggling with bills, contact your supplier. You may be eligible for schemes such as the Warm Home Discount (subject to eligibility and availability) and support via the Priority Services Register for additional help if you have specific needs. Independent advice is available from Citizens Advice and gov.uk.

Where our comparison applies

Our domestic energy comparison is designed for households in Great Britain (England, Scotland and Wales). The energy market in Northern Ireland operates differently with separate suppliers and regulation, so tariff availability and switching options may vary.

Domestic energy comparison FAQs

Will my energy supply be interrupted if I switch?
No. Your gas and electricity are delivered through the same pipes and wires. Only your billing company changes, so there’s no downtime.
How long does an energy switch take?
Most domestic switches complete within about 5 working days once confirmed by your new supplier. You’ll usually have a 14-day cooling-off period in which you can cancel.
What is the Ofgem price cap?
The price cap limits the maximum unit rates and standing charges suppliers can charge customers on standard variable/default tariffs in Great Britain. It is reviewed quarterly. It is not a cap on your total bill, which depends on how much energy you use.
Can I switch if I’m on a fixed tariff?
Yes, but check for early exit fees. Some fixed deals charge a fee per fuel if you leave before the end date. We show any fees alongside your results.
Do I need a smart meter to switch?
No. You can switch with traditional or smart meters. If you have a smart meter, most suppliers can support it. If not, it will still work like a traditional meter until upgraded.
What if I rent my home?
Tenants can usually switch supplier if they pay the bill directly. Check your tenancy agreement for any clauses. If bills are included in rent, discuss options with your landlord.
Can I switch if I’m in debt on a prepayment meter?
You may be able to switch if your debt is below a certain threshold and has been owed for less than a year. Speak to your current supplier for guidance.
What information do I need for the most accurate comparison?
Your postcode, meter type and annual kWh usage for electricity and/or gas from a recent bill give the most accurate results.
