There are around 20 active fuel forecourts in Guernsey. Most are supplied by one of three main distributors: CIFL, Rubis, or GPD. The supplier largely determines when prices change and what loyalty schemes are available.

CIFL-supplied stations typically update prices on Mondays and Tuesdays. Rubis stations update on Fridays. Some forecourts also sell premium grades such as Super Unleaded (RON 97 or RON 99) or biofuel alternatives.

Prices at the pump include Guernsey road fuel duty, currently set at 90.5p per litre. This is separate from UK fuel duty and is one reason island prices move independently from the mainland.
