Garston

At the bottom of the local market, unleaded starts around 144p per litre right now. 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.

The supermarket sites, including Sainsburys and Asda, tend to set the floor for prices here. 6 of the 26 local forecourts are supermarket-run, and the rest split between branded and independent operators.

Costco around Hartspring Lane has been setting the cheapest unleaded price locally of late. Forecourts on St Albans Road and Watling Street carry much of the passing trade, and their prices often move first.

The town's unleaded average sits slightly below the East of England norm at the moment. For diesel, expect an average of roughly 172p 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 Garston regularly, note that the price ordering below changes often enough that last month's cheapest stop may not be this week's.
