Tips for Businesses
Match the signature type to the document – use simple signatures for routine contracts and advanced or qualified signatures for high-value or sensitive agreements. Confirm all parties consent to electronic signing beforehand. Use a reputable platform that generates audit trails, and always store a signed copy securely after execution.
Electronic signatures allow businesses to sign legally binding documents digitally, without the need for pen and paper. In the UK, they are recognised under a clear legal framework and accepted across a wide range of business transactions. This article will explore the legality, benefits, and challenges of electronic signing in business document transactions.
Electronic Signature Regulations
The Electronic Communications Act 2000 and the UK Electronic Identification and Trust Services for Electronic Transactions Regulations 2016 (UK eIDAS) govern the use of electronic signatures in the UK. These regulations have established a clear legal framework for electronic signatures, making them a valid and legally binding way to sign legal documents in various business contexts.
It is no longer a legal requirement to sign most legal documents physically, with electronic signatures now widely accepted across most business transactions
These regulations cover several types of electronic signatures. Let us explore this in further detail below.
1. Simple Electronic Signatures
Simple electronic signatures, also known as basic electronic signatures, are generally accepted for most routine business documents. These can take the form of a scanned image of a handwritten signature or a typed name.
For example, a simple electronic signature could be:
- typing your name at the end of an email;
- clicking an “I accept” button on a website; or
- using a stylus or finger to sign on a touchscreen device.
The Electronic Communications Act 2000 recognises the validity of simple electronic signatures as long as they fulfil the basic requirements of:
- identifying the signatory; and
- indicating their intent to sign the document.
2. Advanced Electronic Signatures (AES)
Advanced electronic signatures offer higher security and authenticity within electronic transactions. They require unique authentication and are often created using digital signature software or hardware tokens.
An advanced electronic signature must be:
- uniquely linked to the signatory;
- capable of identifying the signatory;
- created using electronic signature creation data that the signatory can, with a high level of confidence, use under their sole control; and
- linked to the data signed in such a way that any subsequent change in the data is detectable.
AES is particularly important for transactions involving high-value contracts or sensitive information, such as property agreements or financial contracts.
3. Qualified Electronic Signatures (QES)
Qualified electronic signatures are the most secure form of electronic signature and have the equivalent legal effect of a handwritten signature.
QES requires the involvement of a qualified trust service provider. Parties will likely utilise QES for highly regulated transactions, such as notarised documents or certain land registry applications.
What Types of Documents Can You Sign Electronically?
Most of your business documents can use electric signatures in the UK, including:
- commercial contracts and agreements;
- employment contracts;
- non-disclosure agreements;
- purchase orders and invoices;
- terms and conditions; and
- internal business documents.
However, certain documents still require physical signatures or additional formalities, including:
- wills and codicils;
- certain land transfers and leases;
- powers of attorney (in most cases); and
- documents requiring witnessing under specific statutory requirements.
It is important to check whether your specific document type has any particular signing requirements before proceeding with an electronic signature.

Benefits of Electronic Signatures
There are various benefits to using the aforementioned electronic signatures. Let us explore these in further detail below.
| Benefits of Electronic Signatures | What This Means for Businesses |
| Efficiency | Electronic signatures can reduce the time and effort involved in signing documents. This is especially useful for businesses that regularly send contracts, agreements or forms for signature. |
| Cost savings | Businesses can reduce costs associated with paper, printing, postage, physical storage and in-person signing. Over time, this can create meaningful operational savings. |
| Accessibility | Electronic signatures allow people to review and sign documents remotely, provided they have internet access. This can speed up approvals and make signing easier for clients, employees and other stakeholders. |
| Improved security | Many electronic signature platforms use encryption, authentication and audit trails to help protect signed documents and reduce the risk of tampering or fraud. |
| Environmental impact | Using electronic signatures can reduce paper consumption and waste, supporting a business’ broader sustainability goals. |
How to Make an Electronic Signature Legally Valid
Knowing which type of electronic signature to use is only part of the process. You must ensure the correct application of the signature.
Here are some practical steps to help ensure your electronic signature holds up:
- Choose the right signature type. Use a simple electronic signature for routine documents. Use an advanced or qualified electronic signature for high-value or sensitive contracts.
- Record consent. Make sure all parties agree to sign electronically before the process begins. This can be as simple as a short confirmation email.
- Use a reliable platform. Platforms such as DocuSign or Adobe Sign automatically create audit trails, timestamps and authentication records. These records help prove the signature is genuine if a dispute arises.
- Keep a copy. Store a signed copy of every document securely. Both parties should receive a copy immediately after signing.
- Check document-specific rules. Some documents have additional requirements. Always confirm the rules before sending anything for signature.
Challenges of Electronic Signatures
However, electronic signatures also have some challenges and disadvantages. Let us explore these disadvantages in further detail.
| Challenges of Electronic Signatures | What This Means for Businesses |
| Acceptance and trust | Some clients, suppliers or organisations may be hesitant to rely on electronic signatures, even where they are legally valid. This can slow adoption or require additional reassurance. |
| Technology requirements | Businesses need suitable software or electronic signature platforms. This may create challenges for organisations with limited technology resources or internal resistance to new systems. |
| Compliance and regulation | Some industries, document types or transactions may have specific signing requirements. Businesses should check whether an electronic signature is appropriate for the document being signed. |
| Cybersecurity risks | Because electronic signatures are digital, businesses should protect signing platforms from cyber threats and unauthorised access. Strong security controls help preserve document integrity. |
| User training | Employees and stakeholders may need guidance on how to use electronic signature platforms correctly, particularly during the initial rollout. |
Key Takeaways
While electronic signatures provide significant efficiency, cost savings, and security advantages, they are not without challenges. Building trust, ensuring compliance, and protecting against cyber threats are critical considerations for businesses looking to implement electronic signature solutions.

Frequently Asked Questions
Are electronic signatures legally binding in the UK?
Yes, electronic signatures are legally binding in the UK under the Electronic Communications Act 2000 and the UK eIDAS Regulations 2016. Provided the electronic signature meets the basic requirements of identifying the signatory and indicating their intent to sign, it will generally be valid and enforceable. The level of security required may vary depending on the type of document and transaction involved.
Can I use an electronic signature for a contract with a client?
In most cases, yes. Electronic signatures are widely accepted for commercial contracts in the UK. However, you should ensure that the contract does not fall within the limited categories of documents that require physical signatures or specific formalities.
What is the difference between a simple and an advanced electronic signature?
A simple electronic signature is a basic form of electronic signature, such as a typed name or scanned signature image, that identifies the signatory and shows their intent to sign. An advanced electronic signature (AES) offers greater security as it must be uniquely linked to and capable of identifying the signatory, created using data under the signatory’s sole control, and linked to the signed data so that any subsequent changes are detectable. AES is typically used for higher-value or more sensitive transactions.
Do I need special software to create electronic signatures?
Not necessarily. Simple electronic signatures can be created using basic tools such as typing your name in an email or document. However, for advanced or qualified electronic signatures, you will typically need specialised electronic signature software or services that provide the necessary security features, authentication, and audit trails.
