Newport

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.

8 of the 25 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 Texaco.

Forecourts on Pencarn Way and Lower Dock Street carry much of the passing trade, and their prices often move first. The town's unleaded average sits slightly below the South Wales norm at the moment.

Diesel averages around 180p per litre across the stations listed for Newport. The comparison covers stations up to roughly 10 km out, which keeps out-of-town supermarkets and bypass sites in the same view as the town centre.

Prices in Newport 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.
