Frequently Asked Questions
General Questions
What is DataLedger?
DataLedger transforms raw Companies House filings into structured, searchable UK company financial data. Our datasets include balance sheets, profit and loss accounts, ratios, and company metadata - available through API, AI chat, or bespoke downloads.
Who uses DataLedger?
Fintechs, CRMs, accountants, analysts, journalists, and local authorities who need reliable financial intelligence on UK companies. It’s ideal for prospecting, onboarding, benchmarking, or regional business research.
How is DataLedger different from Companies House?
Companies House provides raw filings. DataLedger normalises, cleans, and structures that data, adding calculated fields, ratios, industry and region tags, and consistent formats that are ready for analysis or integration.
How current is the data?
Our database updates daily as new filings and changes appear in Companies House. This ensures trends and ratios remain accurate and up to date.
Is DataLedger an official government source?
No. We use Companies House as an official source but enhance it for commercial use. DataLedger is an independent data company built by developers who needed structured company accounts themselves.
Data and Coverage
What data do you include?
Our core dataset includes:
Balance sheet metrics (assets, liabilities, equity, current/fixed asset breakdowns).
Profit and loss fields (turnover, profit, margin).
Derived ratios (debt-to-equity, liquidity, asset growth, profitability trends).
Company profile details (SIC codes, address, incorporation date, local authority).
How often is the data refreshed?
Daily for filings and updates; full reconciliations monthly to maintain consistency between ourselves and Companies House.
Which companies are included?
All active UK-registered companies that file electronic accounts - over 5 million records, including SMEs, limited partnerships, and LLPs.
Do you include dissolved or dormant companies?
Yes. Historical and dormant entities are included for trend and risk analysis, though users can filter them out easily via the API.
Are the figures verified?
Yes. Each account record includes flags for verified and calculated values (e.g. cVerified, pVerified) to indicate reliability and derivation method.
API and Technical
What does the API provide?
A RESTful JSON API delivering structured company data: balance sheet, P&L, financial ratios, SIC codes, and metadata. It supports search by name, company number, SIC, region, or financial filters.
Is there documentation?
Yes - full OpenAPI/Swagger documentation is available at api.dataledger.uk/docs/v1.
Can I test the API for free?
Yes. New users receive free tokens to explore the API and CHat interface. Developers can query up to a set number of records before subscribing.
What authentication method is used?
Simple API key authentication via the x-api-key header. Each plan includes a unique key and usage tracking.
Can I integrate with Zapier, n8n, or Google Sheets?
Absolutely. We provide ready-made connectors and workflows for popular automation tools. You can also use the AI-powered CHat assistant for natural-language queries.
AI & CHat Assistant
What is the DataLedger CHat?
It’s an AI-powered assistant that understands natural English queries like “Show me manufacturing companies in Yorkshire with strong balance sheets.” It translates your request into API calls automatically.
Do I need coding skills to use it?
No. CHat is designed for non-technical users who want quick company insights without writing SQL or API queries.
Can I use CHat in my own app?
Yes. The same endpoints can be embedded or connected to OpenAI-compatible interfaces for custom assistants.
Bespoke Datasets
What is a bespoke dataset?
It’s a custom CSV or Excel export filtered to your exact criteria - for example, companies in specific SIC codes, regions, or meeting financial thresholds.
How fast is delivery?
Typically within one business day for standard criteria.
What file formats are available?
CSV, Excel, or JSON. Datasets are suitable for import into CRMs, analytics tools, or data warehouses.
Can I use the data commercially?
Yes. All paid datasets and API subscriptions include a commercial reuse licence.
Legal, Licensing & Support
Is the data GDPR-compliant?
Yes. We only use publicly available corporate information from Companies House.
What’s the licence for using DataLedger data?
