How is this calculated?

This leaderboard ranks companies by their active UK vacancies, regardless of where they are headquartered. Only UK-eligible jobs contribute to the rankings. We periodically check companies' official careers pages and update our listings when vacancies are added or removed. International roles are excluded.

Select a job category to rank companies by their active UK vacancies in that category. Rankings and weekly movements are calculated independently for each category. All jobs counts each distinct eligible vacancy once; category rankings use roles assigned to that category.

Active job counts and ranks are live. Weekly ranking and job-count changes compare the two latest completed Friday 00:00 Europe/London snapshots for the selected category, so a new snapshot does not reset the movement column to zero. Figures reflect advertised vacancies on our platform, not confirmed hires or total recruitment activity.

Live figures calculated 3 Nov 2026, 15:05. Weekly change uses the two most recent completed Friday snapshots for this category.
