A cheaper Pay As You Go plan

Our Pay As You Go plan reflects the true cost of energy, so you’re always on our best deal. And we don’t believe in fixed-price contracts or exit fees, which means you’ll never pay a loyalty tax by sticking around.

Green energy as standard

You don't have to choose between saving money and saving CO2. We supply 100% renewable electricity and 100% carbon neutral gas, and we'll never charge extra for green energy.


Sign up and sit back

Sign up in just 2 minutes - we take care of the rest. We’ll let your old supplier know you’re leaving, and if they charge you exit fees, we’ll refund you up to £120.

Over 50,000 places to top up

Top up at any Paypoint or Payzone - there’s over 50,000 in the UK. Or if you’ve got a compatible smart meter, you can switch to our Smart Pay As You Go plan.

Speedy support when you need it

We're easy to get hold of by phone, email or online chat. We don't like to toot our own trumpet (so it's lucky that our members do it for us).
