UK Price Tracker
We record product prices across major UK retailers on a schedule and keep the history. This page is a live, public view of what we track and where prices are falling right now — over a rolling 90-day window. Free to read, free to cite.
Methodology
Prices are captured on a recurring schedule from retailer product feeds and public APIs, then stored as time-series observations. The figures above cover a rolling 90-day window and are recomputed hourly. “Was” is the first price we observed for a product in the window; “Now” is the most recent. We don’t adjust for promotions or bundles — the numbers are exactly what we recorded. Continuous tracking in this window began 3 July 2026.
