Cheapest first means cheapest in this reading — the order of the prices as published, not what any of these forecourts is charging now. A forecourt that published no price for the selected fuel is listed with an em dash, left out of the ordering and out of the median rather than counted as zero. That is not evidence it does not sell it.
Wider than BT55
The cheapest and dearest E10 here are 0.0p apart. Across the 1,374 districts with enough forecourts to compare, the median gap is 5.0p — how far apart forecourts are in one district is a page of its own.
A postcode district is a sorting boundary, not a driving one. Both of these measure from the middle of the forecourts we hold in BT55 — a point we derived, not your address — and both cross into neighbouring districts wherever the forecourts are.
