Cardiff

At the bottom of the local market, unleaded starts around 156p per litre right now. Unleaded currently varies by roughly 9p per litre between the cheapest and dearest forecourts, which is enough to notice on a full tank.

Supermarket forecourts from Tesco and Asda usually anchor the bottom of the local range. 22 of the 50 local forecourts are supermarket-run, and the rest split between branded and independent operators.

Texaco has been setting the cheapest unleaded price locally of late. Several of the busier sites sit along Ferry Road and Retail Park, so you can check them against each other without leaving your usual route.

Average unleaded here tracks the wider Wales figure closely. Diesel averages around 181p per litre across the stations listed for Cardiff.

Everything within about 15 km of the centre is included, so edge-of-town and retail park sites appear alongside the central forecourts. Prices in Cardiff can move mid-week as well as at weekends, so the ordering above is worth a glance even if you always use the same forecourt.
