Boston

Unleaded currently varies by roughly 2p 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.

Supermarkets account for 2 of the 7 stations here, with branded and independent sites making up the remainder. EG around The Quadrant has been setting the cheapest unleaded price locally of late.

Several of the busier sites sit along Lister Way and Coney Way, so you can check them against each other without leaving your usual route. On average the town runs a touch over the East Midlands norm for unleaded.

For diesel, expect an average of roughly 168p per litre locally. 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 Boston regularly, note that the price ordering below changes often enough that last month's cheapest stop may not be this week's. The table below carries the exact live figures per station, and alerts can flag a drop at the forecourts you actually use.
