Portsmouth

At the bottom of the local market, unleaded starts around 149p per litre right now. Right now roughly 11p per litre separates the cheapest unleaded from the dearest locally.

Supermarket forecourts from Asda and Tesco usually anchor the bottom of the local range. 4 of the 26 local forecourts are supermarket-run, and the rest split between branded and independent operators.

Sainsburys around Fitzherbert Road has been setting the cheapest unleaded price locally of late. Forecourts on Commercial Road and The Bridge carry much of the passing trade, and their prices often move first.

Average unleaded here tracks the wider South East England figure closely. Diesel averages around 165p per litre across the stations we track in Portsmouth.

Everything within about 8 km of the centre is included, so edge-of-town and retail park sites appear alongside the central forecourts. If you drive through Portsmouth regularly, note that the price ordering below changes often enough that last month's cheapest stop may not be this week's.
