Company Check alternative: a REST API instead of a UK credit-report website

Company Check is a browser tool for one-off and subscription UK company and director checks. Prometiam is a REST API that returns the Companies House record — officers and PSC beneficial ownership — plus more countries, corporate events, insolvency notices and sanctions screening. Prometiam does not return a company score; UK annual accounts as filed come from the Scale plan and cover digitally filed iXBRL accounts only; say that up front.

TL;DR

Company Check unlocks UK company and director reports — a 0-100 company score, an insolvency-risk read, County Court Judgments, mortgages, charges and linked-director views — for £20+VAT per report, or £35/month (£350/year) for unlimited reports. No API is advertised. Prometiam is a REST API: the UK Companies House record (officers, PSC) plus every other registry the API covers on one key, with corporate events, insolvency notices across sixteen markets and sanctions screening (beta), priced publicly from a free trial of 500 credits over 14 days. It has no company score and no credit limit; UK annual accounts as filed are available from the Scale plan, for digitally filed iXBRL accounts only (about three in four filings; small and micro companies often have no profit and loss).

Who should pick Company Check

• You want a 0-100 company score and a recommended credit limit before extending trade terms — a judgment call Prometiam does not make.
• You want director-level views: combined finances across a director's linked companies, in a single web report.
• You look up companies occasionally and would rather pay £20+VAT per report, or browse free basic data, than integrate an API.
• You need debt-recovery or Letter Before Action support referred from the same site — outside anything Prometiam offers.

Who should pick Prometiam

• You are building software, not browsing a website: one key, one response shape, across Companies House plus every other registry the API covers.
• You need officers and UK PSC beneficial-ownership data returned as structured fields, not read off a rendered page.
• You screen counterparties against sanctions and US export-control lists (beta) and watch a portfolio for insolvency events across sixteen markets, and for strike-off warnings on UK companies, in the same integration.
• You want published per-call pricing and a 14-day free trial to start today, rather than a flat monthly or per-report fee.

Scope limits, stated plainly

• Prometiam returns no company score and no credit limit — if that is what you need, Company Check's product is built for it.
• Beneficial ownership is the UK PSC register only; every other registry on Prometiam returns officers or directors, not beneficial owners.
• Ireland, Finland, Sweden, Croatia, Belgium, Denmark, Estonia, Slovakia, Switzerland, Latvia, Cyprus, Romania, Lithuania, Canada, Australia, Japan, Israel, Singapore, Colombia, Taiwan, Germany, Ukraine, Serbia, Ecuador, Chile, Mexico, the Netherlands, Brazil, Argentina and the United States are company-level: no officers. Norway has register-change events only, from 14 Oct 2026 (no gazette).
• Insolvency notices are corporate only, across sixteen markets (FR, DE, GB, AT, CH, NO, FI, US, NL, DK, HR, SE, ES, LV, EE, SG).
• Sanctions screening is beta; PEP screening is beta and Spain only, with no relatives or close associates.

What Company Check publishes

Its company-credit-reports page describes a 0-100 company score, a forward-looking insolvency-risk read over 12 months, a recommended credit limit, and Companies House and financial information alongside County Court Judgments, mortgages and charges. A single report unlocks for £20+VAT; a Business Monthly subscription is £35/month and Business Annual is £350/year, both billed with no long-term commitment and both for unlimited reports. Company Check also lists director checks, a company monitoring dashboard, prospecting lists for finding new UK businesses, and a referred debt-recovery and legal service. No API, developer page or machine-readable feed was found on the homepage, the pricing page or the product page checked on 16 September 2026 — the site's own copy describes advanced search, free company accounts and credit reports “across the UK and Ireland”, delivered through the website.

How the two fit together

A credit controller who wants a human-readable judgment on one UK counterparty — score, limit, CCJs — is well served by Company Check's report. A developer building onboarding, monitoring or screening into a product needs a structured response and a key, not a page to read: GET /companies/search?country=GB&company_number= returns the record, GET /companies/{id}?include=all embeds officers, PSC and events, and GET /sanctions/screen?name=&threshold=80 screens the same counterparty. See the Companies House guide for what the underlying UK registry itself contains.

Beyond the registry record

Two derived signals, neither of them a rating. Both are dated facts carrying the source they came from, so whoever reviews your file can check them.

• Companies that stopped filing. A company that quietly stops trading rarely dissolves; the register notices first. The registry_compliance flag returns that state in one shape for Spain (provisional closure of the registry sheet), the United Kingdom (a strike-off proposal, or annual accounts overdue), Ireland (the strike-off list) and Norway (compulsory liquidation). Read it on GET /companies/{id}?include=risk_flags, or list those companies with risk_flag_type=registry_compliance. It is a compliance signal, not an insolvency: read it together with status.
• Public contracts, and the buyer behind them. GET /procurement/awards returns public-contract awards from Spain, France, the UK, Ireland, Poland and Norway by supplier, buyer, identifier, CPV code and date, linked to the supplier’s registry record where the identifier resolves. GET /procurement/buyer/{id} scores the contracting body itself: the probability that its next award draws a single bid, and the probability that a supplier it awards to enters insolvency within two years.

Both are ordinary REST calls on the published price and included in the 14-day trial. Procurement awards cover Spain, France, the UK, Ireland, Poland and Norway (Ireland, Poland and Norway above the EU thresholds only), the buyer scores are Spain and France and in beta, and a score is a prompt to look, never a finding of wrongdoing.

FAQ

No. Prometiam does not return a company score or a credit limit; UK annual accounts as filed are available from the Scale plan, for digitally filed iXBRL accounts only (about three in four filings; small and micro companies often have no profit and loss). It returns registry facts, corporate events, insolvency notices and sanctions matches, with a match_score used only for name-matching confidence.

Does Prometiam cover Ireland the way Company Check does?
Prometiam serves Irish company records from the CRO at company level; officer data for Ireland is not yet available. Company Check's product pages describe UK Companies House data, though its own site copy references Ireland.

Can I get UK beneficial-ownership data from Prometiam?
Yes, from the UK PSC register, embedded in the company and person endpoints. That is the only registry that returns true beneficial ownership on Prometiam.
