General

What is DataLedger?

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.

Where does DataLedger’s data come from?

All DataLedger data is sourced from Companies House. We also use ONS reference data for consistent geography and classification.

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

Which UK companies are included?

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.

Financial data coverage

Do all companies have balance-sheet data?

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.

Do all companies have profit and loss data?

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Most UK companies (for example, micro-entities and small companies) do not publish turnover or profit figures.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.

Why doesn’t every company report turnover or profit?

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.

If profit and loss data is missing, what insight can I still get?

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.

How many years of financial data do you provide?

• API access includes the latest filed accounts, which contain:

  • Current year figures

  • Prior year figures (as reported in the filing)

• Custom datasets include one additional historical year beyond the latest filing.

API access

Do you offer an API for UK company data?

Yes.

DataLedger provides a JSON API that allows you to search, filter and retrieve UK company financial data programmatically.

What data is available via the API?

The API provides access to:

• Company metadata (status, SIC, location, age)

• Structured balance-sheet data

• Profit and loss data where disclosed

• Current and prior year figures from the latest filing

How is the API priced?

API access is priced using a credit-based package system.

Packages start from £5 and scale based on usage volume.

What is a credit?

A credit represents a unit of API usage.

Most endpoints cost 1 credit per request, with some more complex endpoints costing 2 credits.

Is there rate limiting?

Yes.

API usage is rate limited to 50,000 credits per hour across all plans to ensure reliability.

Custom datasets

What is a custom dataset?

A custom dataset is a one-off extract of DataLedger data, built to your specifications.

It is delivered as a file rather than accessed via the API.

What formats are custom datasets delivered in?

Custom datasets are delivered in:

• CSV

• Excel

What can I filter by in a custom dataset?

You can filter by:

• SIC codes

• Location (postcode, local authority, region)

• Company status or age

• Balance-sheet values or ratios

• A specific list of company numbers

How much do custom datasets cost?

Custom datasets start from £295, depending on size and complexity.

Pricing scales based on record count and requirements.

Use cases

Who uses DataLedger?

DataLedger is used by:

• Private equity and investment teams

• Lenders and credit risk teams

• Lead generation and commercial teams

• Software companies building financial products

Can I use DataLedger data for lead generation?

Yes.

Many customers use balance-sheet signals to identify financially relevant companies that do not disclose revenue.

Can I integrate DataLedger data into my own product?

Yes.

The API is designed for commercial reuse and integration into internal tools, platforms and workflows.

Data freshness and quality

How often is the data updated?

DataLedger processes electronic Companies House submissions on an ongoing basis.

New filings are incorporated as they are published.

Do you include paper-filed accounts?

No.

DataLedger only processes electronic submissions, as these can be reliably structured and validated.

Is DataLedger an official Companies House service?

No.

DataLedger is an independent data provider that builds on open Companies House data to provide structured, enhanced access.
