Are Electronic Signatures Legally Binding in the UK?
Yes — electronic signatures are legally binding in the UK for the vast majority of business documents. Here's what the law says, what makes a signature valid, and the handful of exceptions you should know about.
The Legal Framework
Two pieces of legislation govern electronic signatures in the UK:
The Electronic Communications Act 2000 established that electronic signatures are admissible in legal proceedings and have the same legal standing as handwritten signatures, provided the signatory intended to authenticate the document.
Following Brexit, the UK retained and adapted the EU's eIDAS Regulation into domestic law as the UK Electronic Identification and Trust Services (UK eIDAS) framework. This defines three tiers of electronic signature: Simple Electronic Signatures (SES), Advanced Electronic Signatures (AdES), and Qualified Electronic Signatures (QES). For most business contracts, a Simple Electronic Signature — such as typing your name or clicking an "I agree" button — is sufficient.
The Law Commission of England and Wales confirmed in 2019 that electronic signatures can validly execute documents, including deeds, provided the formalities are met.
What Makes an Electronic Signature Valid?
For an electronic signature to be legally enforceable, three elements need to be present:
Intent to sign
The signer must have intended to authenticate the document. This is evidenced by the signer actively clicking to sign, rather than a signature being applied automatically.
Identity of the signer
There must be a way to associate the signature with a specific individual. This is typically achieved via email verification — the signer receives a link to their email address and must click it to access the document.
Audit trail
A record should exist showing who signed, when, from what IP address, and on what device. This is the evidential backbone of any enforceable e-signature.
VedaSign captures all three: signers authenticate via their email link, the signature is applied by an explicit action, and a full audit trail is generated recording the IP address, timestamp, device/browser information, and the email address used. This audit certificate is permanently attached to the signed document.

What About Deeds?
Deeds — such as guarantees, certain property documents, and some powers of attorney — have additional execution requirements under the Law of Property (Miscellaneous Provisions) Act 1989. They must be signed in the presence of a witness. Whilst the signature itself can be electronic, the witnessing requirement typically means the parties need to be in the same physical location, or use a video witnessing arrangement. For most commercial purposes, a contract (rather than a deed) is sufficient and can be signed entirely electronically.
