How this list was made

• 62011 – Ready-made interactive leisure and entertainment software development
• 62012 – Business and domestic software development
• 62020 – Information technology consultancy activities

Location

The whole UK: every company on the register, wherever its registered office is.

Periods compared

Each company's latest annual accounts. The previous year's figure is shown for context and does not affect the ranking.

Ranking

Ranked by the average number of employees in the latest filed accounts. Companies with fewer than 10 employees are left out.

Exclusions

Companies that are dissolved, in liquidation, in administration or proposed to be struck off; dormant companies; and companies whose latest accounts end more than 21 months before the newest accounts in the data (or are dated after it). Figures that cannot be right, which are most likely filing errors, are also left out:

• an employee number identical to the net assets figure, or above 100,000
• more employees than the company's accounts category allows (micro: 50, small: 250, with a margin)
• less than £5,000 of turnover per employee, or a round number of thousands with no turnover to check it against
