Got a best friend or two you’d like to introduce to DuelFuel, so that you can both get exclusive discounts on DuelFuel products? Every super-cool human* you introduce will get a sharp, crisp, freshly printed fiver off their first order over £40 and you’ll get exactly the same; although yours might have a slightly different serial number.

Our bean counters and legal eagles have asked us to point out the following;-
- We’ll ping your super-cool best friend* a discount code for £5 off their first order over £40. Its magic powers are valid for thirty days, but expire thereafter.
- For your friend to qualify for the discount, they need to be a new customer to DuelFuel, over the age of 16, not like Coldplay** and qualify for the conditions of the reward.
