Every company profile on Archive Partners carries a county rank: “#1 in Cumbria,” “#10 in Greater London,” and so on. It reads like a league table, and in one narrow sense it is one. But treating it as a general-purpose size or quality score is the single easiest way to misread this field, so it’s worth being precise about what it counts and what it deliberately leaves out.
What the number actually is
County rank is a company’s position by turnover among the 20 companies we track in its county. That’s the whole definition. Every one of the 47 counties in our dataset has exactly 20 tracked companies, sorted highest to lowest by annual turnover. Rank #1 is simply the largest of that particular 20 by revenue; rank #20 is the smallest. It has nothing to do with digital footprint, filing history, officer count, or any of the other signals we track alongside it, those get their own fields for a reason.
Why the same rank means wildly different things in different places
Because the cohort size is fixed at 20 everywhere but the underlying economies aren’t, rank #1 in a smaller county and rank #1 in a large commercial hub can sit at completely different scales. G & A M Lawson Limited holds the top spot in Cumbria on a turnover of £16.25m. Compare that to Greater London, where the 20th-ranked company we track, Harper’s Home Mix Limited, turns over £79.2m, roughly five times Lawson’s turnover while sitting dead last in its own county’s table. Greater London’s own top spot, Pozitive Energy Ltd, turns over £926.14m, more than fifty times Lawson’s figure. Three companies, three very different scales, and two of them share the exact same “#1” badge on their profile pages.
The same pattern shows up in the middle of the table, not just at the extremes. Surexport UK Ltd sits at rank #10 in Greater London on a turnover of £122.65m. That’s a bigger company than every single business we track in Herefordshire, including the county’s own top-ranked firm, Galebreaker Ltd, on £14.06m, yet Surexport’s position reads as comfortably mid-table rather than dominant. The rank number alone can’t tell you that; you need to look at both figures together.
What this is useful for, and what it isn’t
County rank is a genuinely good tool for one specific question: how does this company compare to its closest local peers, the businesses that share its regional labour market, supply chains, and commercial ecosystem. If you’re screening for the most significant employer or economic anchor within a specific county, rank does that job cleanly and immediately, no calculation required.
It is a poor tool for a different question that looks similar: how big is this company, full stop. For that, the raw turnover figure is the only reliable answer, because rank compresses everything into a position within a same-size cohort regardless of whether that cohort’s companies range from £16m to £16m or from £79m to £926m. A procurement team screening suppliers nationally, or a credit analyst comparing exposure across regions, needs the turnover figure first and the rank second, not the other way round.
The practical takeaway
Treat county rank as a local lens, not a national ruler. It answers “who’s biggest here” reliably and immediately. It says nothing about “who’s biggest overall,” and reading it as though it does will systematically understate large companies that happen to sit in turnover-dense counties, and overstate smaller ones that happen to be the biggest fish in a comparatively small pond. The fix is simple: whenever rank is doing real analytical work, keep the turnover figure next to it. The two together tell you something neither tells you alone.
