Belfast

At the bottom of the local market, unleaded starts around 150p per litre right now. Right now roughly 9p per litre separates the cheapest unleaded from the dearest locally.

The supermarket sites, including Tesco, tend to set the floor for prices here. 5 of the 64 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 BP around Spar Stores. Several of the busier sites sit along Tullynacross Road and M1, so you can check them against each other without leaving your usual route.

Average unleaded here tracks the wider Northern Ireland figure closely. For diesel, expect an average of roughly 172p per litre locally.

The comparison covers stations up to roughly 12 km out, which keeps out-of-town supermarkets and bypass sites in the same view as the town centre. Prices in Belfast 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.
