Bangor

At the bottom of the local market, unleaded starts around 151p per litre right now. The gap between the cheapest and most expensive unleaded in town is around 4p per litre at the moment.

The supermarket sites, including Asda and Tesco, tend to set the floor for prices here. 4 of the 16 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 Asda. Several of the busier sites sit along Circular Road and Rathgael Road, so you can check them against each other without leaving your usual route.

Average unleaded here tracks the wider Northern Ireland figure closely. Diesel averages around 173p per litre across the stations listed for Bangor.

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. 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.
