Companies House runs a free, official API to the public register of UK companies. It returns the company name and number, status, registered address, incorporation date, SIC codes, officers, persons with significant control (PSCs) and filing history.
The API costs nothing. The work is in building the integration properly: keeping the key secure, staying inside the rate limits, mapping the data into your system and handling the awkward cases, such as dissolved companies, LLPs and numbers that don't exist. See the Companies House API gotchas.
Tools like SmartSearch bundle Companies House data into wider AML checks, and they're fine for standard onboarding. They charge per check, and the data stays in their dashboard. A custom integration makes sense when the data needs to live in your own system, or when your volume makes per-check pricing expensive. Thinking of scraping the website instead? Read why the API is the better route.
Not included: AML, sanctions or fraud screening, structured financial figures, and changes to your platform outside the integration.
Payment for Starter and Standard is 50% to start and the balance on completion. Plus is split into three: 40% to start, 30% at the halfway point and 30% on completion. For what drives the price, read what a Companies House integration costs.
The Companies House lookup is a live demo. Search any UK company and see what the API returns.
Send a short written spec by WhatsApp, text, email or the form: your platform, what triggers the lookup and what you need to do with the data. I'll reply within 24 hours with a quote.
Yes. There are no per-search fees or subscriptions, just a rate limit of 600 requests every five minutes. You only pay for building the integration.
No. Filed accounts come back as PDF documents, not as turnover or profit figures you can search. For structured financial data you need a credit reference agency.
Yes. The register covers England, Wales, Scotland and Northern Ireland, and the build handles the different company number formats. Channel Islands and Isle of Man companies aren't on it.
Yes. It's free and registered in your name, so you're never dependent on me for access. I'll tell you exactly what to set up.
If your system has an API, accepts webhooks or has a database the integration can write to, yes. Tell me what it's built on in your spec and I'll tell you how it connects.
Changes are announced in advance. On the optional retainer, updates are covered. Without it, I quote for the change.
