eSignature UK: the short answer
Searched as eSignature UK, electronic signature UK, or "is an e-signature legal in UK", the answer is the same: yes, for ordinary business documents, under Electronic Communications Act 2000 + UK eIDAS (Electronic Identification and Trust Services for Electronic Transactions Regulations 2016). What varies is which documents are carved out and which tier of signature they need, and that is the part worth reading rather than the general rule.
The UK recognizes electronic signatures under the Electronic Communications Act 2000 and the post-Brexit UK eIDAS framework (which retained the substance of EU Regulation 910/2014). UK law identifies three signature tiers: Simple Electronic Signature (SES) for everyday commercial contracts, Advanced Electronic Signature (AdES) for higher-assurance transactions, and Qualified Electronic Signature (QES), the only signature that is automatically equivalent to a handwritten signature with no need to demonstrate authenticity at trial. The Law Commission confirmed in 2019 that electronic signatures satisfy the statutory "in writing" requirement for most contracts, and a witnessed eSignature can validly execute a deed.
What makes an eSignature valid in United Kingdom
- Intention to sign, the signer's subjective intent to authenticate
- Authenticity, the signature is attributable to the named signer
- Identifiability of the signer, link between signature and identity
- Integrity, document hasn't been altered post-signature
- For deeds: witnessing requirement may apply
Where eSignatures are not valid
- Wills (Wills Act 1837, wet-ink + witnesses still required)
- Lasting Powers of Attorney (LPA execution remains formal)
- Some land-registration documents (HM Land Registry exceptions)
- Certain trust deeds and statutory declarations
FAQ
Are electronic signatures legal in the UK?
Yes. The Electronic Communications Act 2000 and UK eIDAS make electronic signatures legally binding for nearly all commercial contracts.
Can I sign a contract under English law with an electronic signature?
Yes. The Law Commission confirmed in 2019 that electronic signatures satisfy the statutory "in writing" requirement and can validly execute most contracts and even deeds (with appropriate witnessing).
Is a QES required for UK contracts?
No. Simple Electronic Signature (SES) is enough for nearly all UK B2B and B2C contracts. QES is reserved for transactions where the law specifically mandates a Qualified signature.
How does Brexit affect eSignature recognition?
UK eIDAS retained the substance of EU eIDAS post-Brexit. UK signatures remain valid in the EU under the mutual-recognition framework, with some specific cross-border QES nuances.
What PDF Verified is, and what it is not
Electronic signature law is settled in broad terms and specific in the details. The ESIGN Act, UETA, eIDAS and their equivalents recognise electronic signatures across more than 190 countries, and what decides a particular case is intent to sign plus evidence connecting the signature to the signer, which is what the audit certificate records. Certain document types carry their own formalities wherever you are: deeds, wills, some property instruments, and anything requiring a witness or a notary. Sign only what you are authorised to sign, since applying another person signature without their authority is forgery whatever tool is used.
PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
