Swansea

The cheapest unleaded in town currently starts near 159p per litre. The very top of the local range is set by a small number of expensive outliers, and most stations sit much closer together than the headline gap suggests.

Supermarket forecourts from Tesco and Morrisons usually anchor the bottom of the local range. 7 of the 37 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 Esso around Mile End Service Station. Forecourts on Upper Forest Way and M4 carry much of the passing trade, and their prices often move first.

Local unleaded prices average slightly above the wider South Wales figure. Diesel averages around 182p per litre across the stations listed for Swansea.

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 Swansea 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.
