UK e-signature law is built on the Electronic Communications Act 2000 (ECA 2000) and UK eIDAS. The ECA 2000 establishes that e-signatures are legally admissible evidence. UK eIDAS provides three signature tiers: SES, AES, and QES.
ECA 2000 and UK eIDAS: the two pillars of UK electronic signature law.
Financial services (FCA), healthcare (CQC/NHS), and legal (SRA) sectors have additional requirements beyond ECA 2000. Zignature's compliance stack addresses the most common sector requirements.

The Electronic Communications Act 2000 (ECA 2000) provides the primary legal basis — Section 7 deems electronic signatures legally admissible. UK eIDAS (retained EU law) provides the regulatory framework for different signature tiers. The Law Commission's 2019 report confirmed the validity of e-signatures for most commercial documents.
Simple Electronic Signature (SES): any electronic mark showing intent — valid for most commercial contracts. Advanced Electronic Signature (AES): uniquely linked to signatory, capable of identifying them, with tamper detection — required for some regulated documents. Qualified Electronic Signature (QES): AES plus a qualified certificate from a trust service provider — highest legal standard.
Some documents still require wet-ink: wills and codicils (Wills Act 1837), land transfer forms lodged at HMRC or Land Registry (legal charges, transfers), and certain deed formats. E-signatures are valid for most commercial, employment, and tenancy documents.
Zignature's audit trail — signer identity, IP address, browser fingerprint, timestamp, and cryptographic document hash — satisfies the admissibility requirements under the Civil Evidence Act 1995 and ECA 2000 Section 7 for electronic signature evidence.
The ECA 2000 applies across the UK. Scottish and Northern Irish contract law has some differences (e.g., Scots law has its own contract formation rules), but e-signatures are legally valid across all UK jurisdictions for most commercial documents.
Post-Brexit, UK businesses must comply with both UK eIDAS (for UK documents) and EU eIDAS (for EU counterparty documents). Zignature supports both standards. For documents requiring QES in both jurisdictions, use a trust service provider recognised in both UK and EU.
