All you need to do is introduce a friend to the service by sharing with them your referral code:

• To access your referral code to share, simply click the main menu (top left "≡" symbol) of the app and select "Free Cleans". All you need to do now is share it with your friends!
  
  
• For every friend you refer, you will receive £10 credit towards your next order and your friend will receive £10 off their first order.
  
  
• There is no limit to how many times you can do this and how much credit you can earn!
