Coulsdon

At the bottom of the local market, unleaded starts around 150p per litre right now. Unleaded currently varies by roughly 13p per litre between the cheapest and dearest forecourts, which is enough to notice on a full tank.

The supermarket sites, including Asda and Tesco, tend to set the floor for prices here. 4 of the 44 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 around Marlow Way. Several of the busier sites sit along Marlow Way and Reigate Road, so you can check them against each other without leaving your usual route.

Average unleaded here tracks the wider Greater London figure closely. For diesel, expect an average of roughly 175p per litre locally.

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. If you drive through Coulsdon regularly, note that the price ordering below changes often enough that last month's cheapest stop may not be this week's.
