Are Electronic Signatures Legal in the UK?

The Legal Basis for Electronic Signatures in the UK

Electronic signatures became legally recognised in the UK through the Electronic Communications Act 2000, which established that electronic signatures are admissible as evidence in legal proceedings and can satisfy legal requirements for a signature. Following Brexit, the UK retained the EU eIDAS regulation domestically as 'UK eIDAS', maintaining the same legal framework for electronic signatures in England, Wales, Scotland, and Northern Ireland. A simple electronic signature — such as typing your name, drawing a signature, or clicking an 'I agree' button — is legally valid for the vast majority of commercial contracts and documents in the UK.

Three Types of Electronic Signatures Under UK eIDAS

UK eIDAS defines three levels of electronic signature, each with different technical requirements and legal weight:

• Simple Electronic Signature (SES): The most common type — includes typed names, scanned signatures, and drawn signatures on screen. Legally valid for most commercial contracts, employment agreements, and business documents.
• Advanced Electronic Signature (AES): Must be uniquely linked to the signatory, capable of identifying them, and created using data under their sole control. Provides stronger evidence of identity and integrity.
• Qualified Electronic Signature (QES): The highest level — requires a qualified certificate issued by a trust service provider. Has the same legal effect as a handwritten signature throughout the UK.

What Documents Can Be Signed Electronically in the UK?

The vast majority of commercial documents can be signed electronically in the UK without any restriction:

• Employment contracts and offer letters
• Commercial leases and tenancy agreements (assured shorthold tenancies)
• Non-disclosure agreements and confidentiality agreements
• Service agreements and terms of business
• Supplier contracts and purchase orders
• Client engagement letters (legal and accountancy)
• GDPR consent forms and data processing agreements

When Wet Signatures Are Still Required

Certain documents continue to require handwritten signatures or specific formalities:

• Wills — must be signed in wet ink and witnessed in person under the Wills Act 1837
• Deeds — require specific execution formalities, though electronic execution is increasingly accepted
• Land Registry transfers — must follow Land Registry practice guides
• Statutory declarations and oaths
• Documents requiring notarisation for use abroad
