Every company that's
actually employing. Updated
when you need it.
A licensed file covering company identity, classification, registered address, and year-on-year headcount for active UK companies with one or more reported employees. Licence the full database, or a single industry, and add monthly updates to keep it current. Need a narrower band — 21–50 staff, 200+, a specific sector? The file scopes to whatever range you need.
One record per company, three groups of fields.
Every row ties a registered company to its identity, its classification, and two years of comparable headcount data — current period against prior period, so growth is visible without a join.
Identity & address
- Company number
- Company name
- Registered address (lines 1–2, town, country, postcode)
- Incorporation date
Classification
- SIC code + description
Headcount
- Employees — this year
- Employees — last year
Active companies by reported headcount
Figures below are as filed with Companies House. The standard product covers active companies with one or more reported employees — pick a single band or any combination, from sole employers up to 200+.
2,106,664 active companies report one or more employees. A further 1,770,000 report zero or have no headcount field on file, and are excluded from the standard product by default.
As of 31st July 2026

A small share of LLPs file no SIC code at all. Address line 2 and country are optional fields on a company's filing and aren't always supplied.

Delivered the way you work.
The dataset is built and hosted on AWS. You choose how it reaches you — a dedicated S3 prefix, a secure download link, an email attachment or a shared cloud-drive folder — all under a direct licence between us, with no third-party marketplace in the middle.
Daily pull
Company filings are pulled from Companies House daily and normalised against the schema — new incorporations, updated accounts, and revised filings are picked up as they land.
Monthly build
On the first business day of each month, the full dataset is compiled into a dated CSV and XLSX export, alongside a checksum manifest for integrity verification, for customers on monthly updates.
Your choice of handoff
Your first delivery is the file you've licensed: the full database or your chosen industry. If you've added monthly updates, a refreshed full file follows every month the same way. You're notified automatically when files are ready.
S3 prefix
A dedicated, encrypted prefix on AWS S3 for your account, with read-only access limited to your own files.
Secure download link
A time-limited signed link to each file, so there are no credentials to hold or set up.
Email attachment
The file sent to your inbox as a CSV attachment, compressed where needed. Best suited to smaller files; if a file is too large for your mail server, we send a signed link instead.
Cloud drive share
A shared cloud-drive folder, set up with you, where each file lands as it's delivered.
S3 access model
Either a scoped IAM user/role limited to your own prefix (read-only, least privilege), or 7-day signed URLs if you'd rather not hold AWS credentials at all.
Encryption
Files held in S3 are encrypted at rest (SSE-S3 or SSE-KMS on request), and every S3 or signed-link download uses TLS in transit.
S3 versioning
Bucket versioning is enabled — every monthly drop is retained under its own dated folder, nothing is overwritten.
File formats
UTF-8 CSV for pipelines, formatted XLSX for analysts, plus a SHA-256 manifest so you can confirm the file arrived intact.
S3 notification
An email (or SNS topic, on request) fires the moment a new month's files land in your prefix.
Why not Marketplace
This is a direct annual licence, not a metered listing — no revenue share, no usage metering, and terms set between us rather than a third party.
Monthly updates
Your licence delivers one annual file. To keep it current, add monthly updates: a refreshed full file each month, delivered by the method you chose. Or reorder the whole file at any time to receive the latest data. £200 a month for a single industry, £400 a month for the full database. See pricing below.
Most company data files are 30% graveyard — dissolved businesses, phantom employers, headcounts from three years ago. Staff Data solved that for us. Every record is an active UK company that's genuinely employing, with year-on-year headcount you can actually trust, and the monthly refresh means it stays that way. Being able to scope the file to a specific staff band or sector saves us cleaning and filtering on our end. Straightforward to deal with, and the product does exactly what it says.

Each licence delivers one annual file. Monthly updates are an optional add-on, or you can reorder the whole file at any time to receive the latest data. Narrower slices by region, or a bespoke field set, are available on request. A written data licence covering permitted use and redistribution is put in place before delivery begins.
Build a bespoke dataset
The full-database licence covers the whole active-employer universe, and the single-industry licence covers one sector. If you need a different slice, we'll scope and quote a custom extract — filtered on any combination of the criteria below, delivered by any of the methods above.
Employee range
- Any single band, e.g. 21–50
- Or a custom range you define
- Combine multiple bands
Geographic location
- Region, county, or post town
- Postcode area or district
- England, Scotland, Wales, or NI
Industry
- One or more SIC codes
- Sector groupings on request
- Exclude sectors instead, if easier
Tell us the range, location, or sector you need and we'll come back with a scoped quote based on what's involved in delivering it.

Where does the underlying data come from?
Company filings held at Companies House, published under the Open Government Licence. What you're licensing here is the extraction, structuring, and headcount modelling layered on top, delivered on a fixed monthly schedule.
Why not deliver through AWS Marketplace?
Marketplace suits metered, self-serve products. This is an annual licence with optional monthly files. We deliver by S3, secure download link, email or a shared cloud drive, so you get the same AWS-hosted data without marketplace fees or listing overhead.
Can we get historical months?
Yes — past monthly snapshots are available outside the standard tier. Get in touch and we'll scope it against what you need.
What happens if a filing is corrected after delivery?
Corrections are picked up in the next daily extract and reflected in the following month's file for customers on monthly updates. Each monthly export is a full snapshot, not an incremental diff, so you always have the complete current picture.
