How do I get a 60 litre cylinder refill(s) when the one(s) I have is/are empty?

Place an order for a 'gas exchange’ When you receive your gas refill, inside your package you will also find a Collect+ returns label. Package the empty cylinder/s up using the box your gas refills arrived in. Apply the Collect+ returns address label and take to your nearest Collect+ store, which can be found here. Collect+ will then return the cylinder to us. PLEASE NOTE: At the time you order we will charge you for a full cylinder. (Cylinder User Licence Fee and gas content). Once you return to us the empty cylinder/s you currently hold we will automatically credit you for the empty cylinder/s once we receive it in our warehouse. Payments can take 2-5 working days to show on your card. The credit will be applied to the same credit card you used for the purchase of the gas refills. Please make sure to keep your receipt for the return of the cylinder.
