Barry

At the bottom of the local market, unleaded starts around 148p per litre right now. The gap between the cheapest and most expensive unleaded in town is around 6p per litre at the moment.

Supermarket forecourts from Asda and Morrisons usually anchor the bottom of the local range. 6 of the 10 local forecourts are supermarket-run, and the rest split between branded and independent operators.

The low end of the market has recently been held by Tesco around Culverhouse Cross. 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 South Wales figure closely. Diesel averages around 162p per litre across the stations we track in Barry.

The comparison covers stations up to roughly 8 km out, which keeps out-of-town supermarkets and bypass sites in the same view as the town centre. Prices in Barry 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.

Use the live table for the exact prices at each site, or set an alert if you would rather be told when your usual stations drop.
