Firmwatch is a software-as-a-service product that monitors UK companies registered at Companies House and sends alerts when their records change. Users add companies to their portfolio by entering company numbers or uploading a CSV file. The product then tracks those companies against the Companies House register and notifies users of changes, including winding-up petitions, liquidation, administration, strike-off action, overdue annual accounts, overdue confirmation statements, director appointments and resignations, registered office changes, and newly registered charges. Alerts can be filtered by type and severity. Users can choose between instant email notifications and a daily digest. Scheduled deadline reminders for accounts and confirmation statements are staged at 60, 30, 14, and 7 days before the filing date, as well as on the due date and when overdue. All plans include unlimited team members, bulk CSV import, change history, and CSV export. Pricing is tiered by portfolio size, starting at £19 per month for up to 100 monitored companies and ranging to £299 per month for up to 10,000. A 7-day trial is available and there is no minimum contract. Data is sourced from the official Companies House register and refreshed multiple times per day. Firmwatch is not a credit reference agency and does not provide credit scores, credit limits, KYC, AML, or sanctions checking. Typical use cases include client compliance monitoring for accountancy practices, customer and supplier risk monitoring for credit control and finance teams, and tracking of filing deadlines across multi-company portfolios.
