Company sizes
Our company sizes are based on the UK's legislative definition on company sizes.
Company size rules changed (from 6 April 2025)
Logic: Companies now meet both conditions (turnover and employees) in our checks.
New limits (old in brackets):
-
Micro: Turnover ≤ £1m (£632k) and Employees ≤ 10
-
Small: Turnover ≤ £15m (£10.2m) and Employees ≤ 50
-
Medium: Turnover ≤ £54m (£36m) and Employees ≤ 250
-
Large: Anything above the Medium caps (e.g. turnover ≥ £54m).
Action: Recheck your company sizes.
Here are our company size definitions:
| Company Size | Annual Turnover (£) | Number of Employees |
| Micro | Less than 1m | Less than 10 |
| Small | Less than 15m | Less than 50 |
| Medium | Less than 54m | Less than 250 |
| Large | More than 54m | More than 250 |
Our company sizes are based on the UK’s legislation definition on company sizes. We also have a category for no employees or turnover.
A given company must meet both conditions to be categorised accordingly. If a company meets only one condition, its company size categorisation will only increase when it meets both.
A company must have a registered postcode to be categorised into a company size bracket.
