Tools (19)

`accounts`read-only	The company's latest filed accounts read into plain figures, this year and last. From Companies House's tagged (iXBRL) accounts document - net assets, current assets, cash, debtors, creditors due within and after a year, equity, turnover and profit where the accounts include them, average employees, for the current and prior period; audit status, standards, dormant flag; what the accounts leave out. Accounts filed as a PDF can't be read and the call's credits go back.
`aml_register`read-only	Is a business on HMRC's Money Laundering Regulations supervised business register, for what, and since when. Matched on the business's name as the register writes it (a company number brings its registered and former names), with the register's postcode district checked against the registered office. Current registrations with sectors and status (Approved, Applied, Expired), former ones with the date they went, and every change recorded for the name since 7 October 2026. HMRC is one supervisor among several, so absence never means unsupervised. People never loaded.
`charges`read-only	A company's registered charges in plain English. From the Companies House register of charges - total and outstanding, the lenders (individuals never named), what each secures and over what, fixed or floating, a floating charge over everything, and the latest creation date.
`charity_check`read-only	Is this a registered charity, is it in good standing, and what do its accounts say. Read live from the Charity Commission for England and Wales' register, by charity number, by company number (matched through the Companies House number the register holds) or by name (up to three matches, registered first). Registered or removed with dates and reason; CIO or charitable company; insolvency, administration and interim-manager flags; reporting status; latest accounts and up to six years of income and spend broken down; what it does, for whom and where; trustee count and chair; governing document, objects, other regulators. England and Wales only. Trustees counted, never named. Contains information from the Charity Commission, Open Government Licence v3.0.
`company_search`read-only	Search UK registered companies. Companies House search, cleaned and confidence-ranked (company-level only, never officer personal data).
`contracts_won`read-only	Public-sector contracts a UK company has been awarded. From Contracts Finder and Find a Tender award notices — count, notified value, top buyers and the latest awards. Matched by company number where a notice gives one, else by exact registered name.
`cqc_check`read-only	Is this company a CQC-registered care provider, how are its services rated, and has that changed. Matched on our daily copy of the Care Quality Commission's register of providers (the CQC's own Companies House number, then the company's registered and former names, or a CQC provider or location id); the provider and up to twelve of its registered locations are then read live from the CQC. Registered or deregistered with dates; the kind of provider; every location (care homes, agencies, surgeries, clinics) with its overall rating, the five key questions, inspection and report dates; every change recorded for it since 2 October 2026. England only. Organisations and services only, never people. Contains CQC information licensed under the Open Government Licence v3.0.
`deadlines`read-only	Every deadline a UK company has, sorted, with days left. Accounts and confirmation statement (Companies House), each director's and PSC's identity-verification date as counts (the earliest among those not yet showing as verified), the ICO data protection fee renewal (the fee register entry matching the company's name), and the next payment practices and gender pay gap reports where the company reports them. Overdue first. The reply carries the address of a free calendar feed for the company.
`distress_signals`read-only	What the Companies House register shows about a company's health. Status, strike-off proposals, insolvency cases, overdue filings, recent charges and directors leaving — each graded serious / watch / info with a date, plus a one-line summary. Matched by company number only.
`gender_pay_gap`read-only	An employer's gender pay gap reports, read and benchmarked. Median and mean gaps, bonus gaps, women by pay quarter, year-on-year trend and rank against all reporters and the sector.
`late_payment`read-only	Statutory interest and fixed compensation on a late business invoice. Under the Late Payment of Commercial Debts (Interest) Act 1998, interest at 8% over the Bank Rate on the previous 30 June or 31 December (each half-year at its own rate), simple, by the day, from the day after the due date to the paid date (today if unpaid), plus the fixed compensation (£40 / £70 / £100 by the invoice's size). The Bank Rate is read from the Bank of England's page daily.
`ownership`read-only	Who controls the company, followed up the register. The people-with-significant-control chain followed company by company while the controller is a UK-registered company (up to five levels) - each company's name, number, status and insolvency flag, what each controller holds, where the register ends (a foreign parent, a listed company, a PSC statement), and any trouble above. Individuals counted, never named.
`payment_practices`read-only	How fast a large UK company pays its suppliers. From the company's statutory Payment Practices reports (OGL v3) — average days to pay, share paid late against agreed terms, terms, trend over its last reports, benchmark against all recent reporters, and a plain reading for suppliers. 1 credit. A name also returns otherMatches (other reporting companies it matches, by number).
`ppn_018`read-only	A company's statutory payment reports against the PPN 018 tests and the Fair Payment Code tiers. The last two Payment Practices reports read against PPN 018's tests (at least 95% of invoices paid within 60 days, 90% with an action plan; all invoices paid within an average of 45 days) and the Fair Payment Code's percentage tiers (Gold 95% within 30 days; Bronze 95% within 60; Silver can't be judged from the report). A company that doesn't report is said so.
`public_record`read-only	Everything the public record says about a UK company, joined and read. Registry facts, distress signals, directors' and PSCs' ID verification against the deadline, and (for large companies) the payment-practices record, with the three things most worth knowing first. Also public contracts won, the gender pay gap, Environment Agency registrations and a UK Sanctions List check.
`registers`read-only	Environment Agency registrations and a UK Sanctions List check for one company. Waste carrier / broker / dealer status and expiry, permits, exemptions and enforcement actions (England), plus whether the company's number, name or former names match an entity on the UK Sanctions List (a lead to confirm, never a finding).
`sponsor_licence`read-only	Is an organisation on the register of licensed sponsors (workers), on which routes and at what rating. Matched on the organisation's name as the register writes it (a company number brings its registered and former names), with the register's town checked against the registered office. Current licences, former licences with the date they went, and every change recorded for the name since 6 October 2026.
`sra_check`read-only	Is this an SRA-authorised law firm, what kind, since when, and has that changed. From our daily copy of the Solicitors Regulation Authority's register of regulated organisations. Matched on the register's own Companies House number, then the company's registered and former names, or by SRA number. Authorised, authorised with conditions, ceased, revoked or intervened, with dates; the kind of firm; work areas, offices and head office; trading and former names; every change recorded for the firm since 8 October 2026. Firms only, never individuals. Data supplied by the Solicitors Regulation Authority.
`will_they_pay`read-only	A large customer's payment habits from the supplier's side, with what its lateness is worth on your invoice. From the company's statutory Payment Practices reports - typical days to pay against your terms, the share paid late and past 60 days, the trend over its last reports - and the statutory interest plus fixed compensation its typical lateness is worth on an invoice of your size. A company that doesn't report is said so.
