How this list is chosen

Ranked by data, not by deals

Chosen automatically: Every match comes straight from our live catalogue, collected from UK specialty roasters’ own shops. Nothing is hand-picked, and no roaster can pay to appear.
The bar to appear: Only coffees that are in stock and carry a comparable price per kilo qualify — sold-out and unpriceable products are excluded. If fewer than five clear the bar, we don’t publish the page at all.
The ranking: Ordered by price per kilo, cheapest first — a straight calculation with no editorial overrides and no sponsored slots. All 13 qualifying coffees are shown.
Kept current: Prices and stock are re-checked on a rolling crawl of each roaster’s site, and this page rebuilds against the live data roughly every hour. The roaster’s checkout is always the final word.

We may earn a commission when you buy through our links — it never affects what’s listed or how it’s ranked. Read our full methodology or how we make money.
