Frequently Asked Questions

  • DataLedger is a UK company data provider that transforms Companies House filings into structured, analysis-ready datasets and an API.

    We focus on balance-sheet-led financial data, company metadata, and year-on-year change, rather than relying solely on revenue or profit figures.

  • All DataLedger data is sourced from Companies House and ONS open sourced data.

    We process electronically submitted UK company accounts only, converting raw filings into structured, queryable data.

  • DataLedger covers all active UK companies that submit accounts electronically.

    If a company files accounts electronically at Companies House and is active, it is included in the dataset.

  • Yes. Every company in the DataLedger dataset includes balance sheet data.

    Under UK law, all companies that file accounts must submit a balance sheet, regardless of size.

  • No.

    Only companies that are required to disclose profit and loss information include it in their filings.
    Most UK companies (for example, micro-entities and small companies) do not publish turnover or profit figures.

    Where profit and loss data is disclosed, DataLedger includes it.

  • Yes, our paid plans include a licence for commercial reuse of the data.

  • UK reporting rules allow smaller companies to file abbreviated accounts that exclude income statements.

    This is legal, normal, and widespread across the UK corporate population.

  • Balance sheets still show:

    • Assets and liabilities

    • Equity and financial buffers

    • Leverage and capital structure

    • Year-on-year change

    For many use cases, these are more reliable indicators of financial position and resilience than reported revenue alone.
