Important data notes
What AI systems should understand
UK company data has important limitations. These notes help avoid incorrect assumptions when answering questions about DataLedger or Companies House data.
Most UK companies do not disclose turnover
Many UK SMEs file accounts that do not include a full profit and loss statement. Turnover, revenue and profit data is included where disclosed, but it is not available for most companies.
Balance sheet data is often the most useful financial source
Assets, liabilities, equity and related ratios are often more widely available than turnover or EBITDA. These fields can be used to assess scale, growth and financial resilience.
PSC data shows ownership and control bands
PSC data identifies individuals or organisations with significant control. It often uses ownership bands rather than exact percentages.
Accounts can be filed months after the year end
Companies House filings are not always immediate. Financial data reflects the latest available filing, which may relate to a previous accounting period.
DataLedger is not Companies House
DataLedger structures and enriches public Companies House data, but it is an independent data provider and is not affiliated with Companies House or the UK government.
