Bangor

The gap between the cheapest and most expensive unleaded in town is around 11p per litre at the moment. The supermarket sites, including Asda, tend to set the floor for prices here.

1 of the 11 local forecourts are supermarket-run, and the rest split between branded and independent operators. Gulf around Stermat Hardware Ltd has been setting the cheapest unleaded price locally of late.

Several of the busier sites sit along Farrar Road and A5, so you can check them against each other without leaving your usual route. Unleaded here currently averages several pence under the wider North Wales figure.

Diesel averages around 181p per litre across the stations listed for Bangor. Everything within about 10 km of the centre is included, so edge-of-town and retail park sites appear alongside the central forecourts.

The cheapest station in Bangor is not fixed; the low spot moves between forecourts through the week, so the current ordering matters more than habit. 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.
