Compare electricity and gas prices for your consumption

These comparison sites work with current supplier tariffs. Enter your yearly usage and postcode, tick prepayment or Economy 7 if that is your meter, and you have a result in two minutes. You sign up directly with the supplier.

  • Yearly bill (consumption in kWh)
  • How you pay and meter type (prepayment, Economy 7)
  • Your postcode

Comparison sites

How we order them: sites that pay us a commission come first and carry the label Partner link. The others pay us nothing and we list them because more choice helps you. Where the regulator runs its own comparison tool, you find it on this page too.

What happens after you click

  1. On the comparison site you enter your consumption and postcode and see prices. Nothing is signed at this point.
  2. If you decide to switch, the site asks for your name, address, e-mail and payment details, sometimes a phone number. That is normal: a switch cannot be arranged without them.
  3. The new supplier does the rest, including telling your old supplier. Your supply is never interrupted and you have 14 days to change your mind.

Comparing deals in Great Britain: six checks

  • Compare against the price cap. A fix is only worth taking if its annual cost beats the capped standard variable tariff for your usage (£1,723 for a typical home from 1 October 2026).
  • Say how you really pay. Prepayment, Direct Debit and paying on receipt of a bill are priced differently, so tick prepayment or Economy 7 if that is your meter.
  • Use your own annual kWh from a bill, app or statement, and compare the total including standing charges.
  • Check the exit fee and the end date. With 49 days or fewer left on a fix you can leave without paying one.
  • Many sites don't cover the whole market, so try two before you decide.
  • Never give your meter number or bank details to someone who knocked or cold-called. A genuine switch is one you start.

Facts, not promises

How switching works in Great Britain

  • Suppliers must complete a switch within 5 working days. If they don't, the new supplier must pay you £40.
  • You can cancel a switch within 14 days, without paying a fee.
  • Only the company that bills you changes. The meter, pipes and wires stay the same and nobody needs to visit.
  • If a supplier goes bust, Ofgem moves you to a new one and your supply is not interrupted. Household credit balances are protected.
  • No exit fee in the last 49 days of a fixed deal, and none at all on a standard variable tariff, which Ofgem's price cap limits (£1,723 a year for a typical home from 1 October 2026).
  • Complaints go to the Energy Ombudsman free of charge once the supplier has had 8 weeks to sort them out.

Count the total yearly cost

Not just the unit price but also the standing charge. With low consumption the standing charge can decide.

Check the contract term

Fixed period, early-exit fees and automatic renewal. Set up the contract alert.

Never agree at the door

A genuine switch is one you start yourself, online or by phone. Never give your meter number or bank details to someone who knocked on your door or cold-called you.

Read before you compare

Common questions

Which comparison site is best?
All listed sites work with current supplier tariffs. They differ in how many suppliers they cover and whether they arrange the switch for you. Enter your consumption into two of them and compare the results.
What should I prepare?
Your last yearly bill: consumption in kWh, tariff or meter type, and your postcode.
Is switching safe?
Yes. The network operator and meter do not change and supply never stops. The new supplier handles the switch, including telling your old supplier.
How does Switchly earn money?
If you go to a comparison site through a link marked Partner link and use its service, that site pays us a commission. The service and the price are the same for you. Commission does not influence our articles. It does influence the order on this page: paying partners come first and free alternatives follow.
