Help a friend to join us and you’ll both get up to £20 credit*

Encourage a friend to go green, and help their community by switching to CitizEn Energy’s competitively priced two year tariff*. They could save hundreds by switching, and you’ll both get up to £20 credit.

Here’s how it works:

  1. Give your friend your CitizEn Energy account number (this is a 9-digit number and will start with a 5). Log in to your account to find this. 

  2. Your friend should then reference this number when they sign up – either over the phone, or online (in the ‘Originator code’ box) during the sign up process. 

  3. You will both receive up to £20 credit to your CitizEn Energy account (£10 for gas tariff switched and £10 for electricity tariff switched).

Forward this link (along with your account number) to your friends today, to see if you could both save!


Terms and conditions

*You’ll get the credit added to your account once your friend has signed up to our 2 year fixed tariff – either gas, electric, or both (the credit will be applied to your energy accounts within three months of your friend joining). The account credits will only be applicable to customers that successfully complete their switch. Any cancellations or objections etc. won’t be eligible. This offer is limited to the first 1,000 referrals from 1 Aug 2019.

Our green electricity tariffs are certified as being sourced from UK based wind and solar generators. For every Megawatt hour (MWh) of electricity purchased for our customers, we also purchase a Renewable Energy Guarantee of Origin (REGO) certificate, which proves the electricity is certified as being sourced either directly from the renewable generators or through a green wholesale energy provider.
