Shares are worked out from the rounded counts. No figure filed means the company has not filed a machine-readable headcount: it may be large or small, and it is never counted as zero. A filed 0 is a real answer and sits under micro.
What is counted
- Sector
- Engineering design and consultancy (SIC 71.12), and the engineering manufacturing divisions: fabricated metal products, electronics, electrical equipment, machinery, motor vehicles, other transport equipment including aerospace, and the repair and installation of machinery (divisions 25 to 30 and 33). Architecture and technical testing are not included. SIC 2007: division 25 (Manufacture of fabricated metal products, except machinery and equipment); division 26 (Manufacture of computer, electronic and optical products); division 27 (Manufacture of electrical equipment); division 28 (Manufacture of machinery and equipment n.e.c.); division 29 (Manufacture of motor vehicles, trailers and semi-trailers); division 30 (Manufacture of other transport equipment); division 33 (Repair and installation of machinery and equipment); 71121 (Engineering design activities for industrial process and production); 71122 (Engineering related scientific and technical consulting activities); 71129 (Other engineering activities).
- Companies
- Active companies on the Companies House register, placed by registered office postcode, which is approximate near a border. A company with several of these codes counts once.
- Headcounts
- 76% of these companies have an employee count in accounts we have read. The rest are shown as No figure filed, never as zero.
- Dates
- Each company's size is from its latest filed accounts, read up to 24 October 2026. Accounts are filed up to nine months after the year end, so a figure can describe a year that ended some time ago.
- Rounding
- Counts are rounded to two significant figures, and under 20 are shown only as fewer than 10 or fewer than 20, so no count points at a single company. The report is exact.

How up to date is this?
The register is the Companies House snapshot of 1 September 2026, and new accounts are read every day; these figures use accounts filed up to 24 October 2026. Each company's headcount is as of its own accounts date, which can be a year or more before the day it was filed.
