## Tools (5)

- `charity_profile`: Full profile of a charity in England and Wales by charity number: status, what it does, address and contacts, latest income and spending, staff, volunteers, trustees and five years of income history. (cost: 2 credits)
- `charity_search`: Find a registered charity in England and Wales by name and get its charity number, status and registration date. Use to check a charity is real before donating, partnering or paying it. (cost: 1 credit)
- `company_accounts`: Headline figures from a UK company's latest filed accounts at Companies House: net assets, cash, debtors, creditors, employees and, where published, turnover and profit, with the prior year for comparison. Works for most small and medium companies that file digital accounts; large companies and groups usually file PDF only, and then the tool says so and links the filing. Use for supplier and credit checks: is it solvent, how much cash, is it growing. (cost: 3 credits)
- `fca_firm`: Full FCA register check on a financial firm by firm reference number (FRN) or name: authorisation status, what it is permitted to do, trading names, addresses and complaints contact, regulators, client money, and any fines or enforcement history. Use before dealing with a bank, lender, broker, adviser, insurer or investment firm, and to spot cloned firms. (cost: 2 credits)
- `fca_individual`: FCA register check on a person by individual reference number: approval status, current and past regulated roles and the firms they hold them at, and any disciplinary history. Use to check a financial adviser, mortgage broker or senior manager. (cost: 1 credit)
