Bank-Grade Security for
UK Accounting Practices
We adhere to the highest standards of UK data protection, HMRC security mandates, and regulatory oversight to safeguard sensitive financial data.

All practice database entities, tax schedules, client bank transactions, and uploaded receipt attachments are stored exclusively in UK data centres (London region), fully compliant with post-Brexit UK regulations.
HMRC Anti-Fraud API Standards
Built to HMRC's rigorous digital API technical specifications. Features strict transaction-level audit logs, automated anti-fraud telemetry headers, and cryptographically verified submission tokens.
Bank-Grade 256-Bit AES Encryption
All client entity records and sensitive tax numbers (UTR, NI, VAT) are protected by AES-256 encryption at rest and enforced TLS 1.3 encryption in transit with HTTP Strict Transport Security (HSTS).
Granular Role-Based Access (RBAC)
Provide fine-grained permission controls across Partners, Senior Accountants, Junior Bookkeepers, and Clients with dedicated practice isolation and end-to-end audit logging.
Our Architectural Security Principles
UK Post-Brexit Data Sovereignty
Under UK GDPR and the Data Protection Act 2018, accounting firms are legally accountable for cross-border data transfers. LedgerHQ ensures that 100% of client financial data, payroll details, and tax schedules reside strictly within ISO 27001-certified UK sovereign data centres (London region).
Cryptographic HMRC Audit Trails
Every digital submission made through LedgerHQ transmits full HMRC fraud prevention telemetry headers, recording client IP, agent credentials, submission timestamps, and digital signing hashes.
Enterprise Practice Isolation & Privacy
Every practice operates within a dedicated, cryptographically protected environment with enforced database-level isolation. Your firm's client entities, tax filings, and document vaults remain completely private and accessible exclusively to your authorised team members.
Continuous Backups & Disaster Recovery
Your practice data and client records are protected by continuous automated backups, encrypted multi-zone redundancy, and enterprise disaster recovery protocols to ensure complete data integrity and uninterrupted business continuity.
