Your postcode: where you live will affect which electricity companies you'll be able to switch to. Which? Switch needs your postcode to be able to compare the electricity tariffs from suppliers in your area.
Existing electricity supplier and tariff: how much you'll be able to save by switching electricity suppliers will depend on who you're currently with, and the tariff you're on. Find the name of your tariff on your last bill or by contacting your current energy supplier.
How much energy you use: the amount of money you could save by switching electricity supplier also depends on how much electricity you use. You can work this out accurately by looking at your last couple of electricity bills, or estimating how much you pay for electricity each month.

Green electricity suppliers

All energy suppliers are obliged to generate a certain portion of energy from renewable sources. If you're looking for a greener option, Which? Switch allows you to rank your results by the percentage each electricity supplier generates via renewable means.

Most electricity suppliers also offer 'green' energy tariffs - most won't provide your home with energy sourced directly from clean or renewable energy projects, but will ensure that some of your money goes towards green energy, carbon-offsetting or other environmental projects.
