Four jobs, one source of UK company data

Check a company before you commit

Accounts, owners and compliance flags in plain English - before you sign a lease, extend credit, or take on a supplier.

• See director history, PSC ownership and account status in one page
• Buy a one-off report (£4.99) or search free, no account needed
• Watch the company afterwards for compliance-risk changes

e.g. a landlord vetting a corporate tenant before signing a commercial lease

Keep a client book compliant

Know which clients will get blocked before Companies House tells them - and bill the chase, not the panic.

• Scan a whole client list against the live register free
• See exactly who is unverified at each client and their own deadline
• Turn the gap report into a ready-to-send chase pack

e.g. an accountancy practice with 180 clients preparing for ECCTA enforcement

Build UK company data into your product

The Companies House plumbing you'd rather not build: parsed iXBRL, resolved PSC chains, cached and rate-limit-proof.

• Structured financials, director networks and PSC chains in clean JSON
• Cached and rate-limit-proof - no Companies House quota to manage yourself
• One key covers everything, with starter kits in Python, Node and curl

e.g. a salary-sacrifice platform checking employer eligibility inside its own signup flow

Qualify a whole list

Turn a list of company numbers into a qualified, risk-scored book overnight.

• Submit up to 500 company numbers in one batch
• We manage the Companies House rate limit for you
• Poll for results - no timeouts, no queuing logic on your side

e.g. an FX provider qualifying counterparties before onboarding
