About companydig
UK company accounts, decoded
companydig turns the accounts UK companies file at Companies House into something you can read at a glance: every year from incorporation to the latest filing, as profit and loss, balance sheet and cash flow statements, with charts, ratios and the story behind the numbers.

Where the data comes from
Everything comes from Companies House: the company register, filing history, officers, persons with significant control, charges and insolvency records through its public data API, and the accounts documents themselves.
Tagged accounts (iXBRL)
Read exactlyMost accounts filed in recent years carry machine-readable tags, so every figure is taken exactly as filed.
Scanned accounts (PDF)
Read with OCROlder and some larger companies' accounts are images. These are read with optical character recognition (OCR), which is less reliable.
How accuracy is checked
- Check the arithmetic. Every year's figures are tested against the accounts' own sums: gross profit should equal revenue less cost of sales, net assets should equal total equity, and so on.
- Repair obvious misreads. Where a scanned figure has clearly been misread (a lost digit or minus sign) and only one correction makes the sums add up, it is corrected and marked.
- Flag the rest. Anything that still doesn't add up is highlighted in the tables, and hovering over a figure shows which filing it came from.
For AI assistants and developers
The same data is available in forms that AI assistants, agents and scripts read easily. No account or key is needed.
