Comparison Guide: 7 Best Electronic Signature Apps in the UK (2025)

Signing documents doesn’t look the way it used to. Gone are the days of printing contracts, scanning signatures, or waiting on postage. Whether you’re closing a client deal or approving a supplier agreement, doing it online with an electronic signature is now the standard — not a workaround.

For UK businesses, freelancers, and teams working remotely, using a trusted eSignature app saves time, reduces admin work, and makes the process legally sound. And depending on your needs, you don’t always have to pay — some tools even offer electronic signature for free, with a limited number of documents or a basic free e sign plan.

But with so many options out there, choosing the right signature app can be confusing. Some are built for high-volume workflows, others are ideal for one-off signings. Some focus on privacy and legal compliance, while others prioritise speed or integrations.

In this guide, we’ve tested and shortlisted the 7 best electronic signature apps available in the UK. Whether you’re after something simple or something that fits into a broader document workflow, you’ll find a tool here that works for your setup.

What Makes a Good eSignature App?

Not all electronic signature tools are created equal. While most apps will let you add a signature to a document, the real difference lies in how easy they are to use, how well they handle compliance, and whether they support the way your business operates — especially if you’re based in the UK.

Here’s what we looked for when selecting the best tools:

✅ Legally Recognised Signatures

An app must provide signatures that are legally valid under UK law and eIDAS regulations. This includes audit trails, timestamps, and tamper-proof records, especially important for contracts, agreements, or onboarding workflows.

✅ Ease of Use

The best eSignature apps make things simple for both sides. Whether you’re signing a contract or sending one out, the process should take minutes — without creating an account or installing extra tools.

✅ Security and Verification

Some tools go beyond basic signing with digital signature support — which adds cryptographic protection and proof of signer identity. This is especially useful when signing legal, financial, or client-sensitive documents.

✅ Templates and Automation

If you’re sending similar documents regularly, the ability to use templates or auto-fill fields is a huge time-saver. Some tools also offer integrations with CRMs or cloud storage, so everything stays connected.

✅ Free Plans or Flexible Pricing

Not everyone needs an enterprise solution. We made sure to include options that offer e signatures free or electronic signature for free through a trial or limited monthly plan — especially useful for freelancers or early-stage startups.

How Finexer Fits Into Your Digital Signing Workflow

Choosing the right electronic signature tool is just one part of building a smooth, secure customer journey. Before documents are signed, there’s often a bigger need: making sure you’re actually dealing with a real person or business.

That’s where Finexer comes in.

Whether you’re signing agreements with customers, partners, or contractors, Finexer can help you verify identities before anything is signed — using Open Banking, document checks, and facial recognition.

How It Works with Any Signature App

Finexer runs pre-signature verification, so you know who’s on the other end before they even open the document. It works alongside any eSignature app, and here’s what it adds:

✅ Bank-Verified Identity

• Check if your customer’s name matches their bank records
• Get a clear pass/fail match before sending a contract

✅ Face Match & Document Extraction

• Upload a selfie and ID (passport, driving licence, etc.)
• Finexer compares the two and gives a similarity score
• Helps reduce fraud, fake accounts, and identity theft

✅ Financial Insight Reports

• Get cash flow and transaction summaries for KYB
• Understand financial behaviour before signing long-term contracts or onboarding clients

✅ Single Workflow, Full Coverage

• Combine bank data, facial recognition, and document checks
• Everything feeds into a single verification report you can store with the signed document

Whether you’re using DocuSign, Signable, or any other tool from this list, Finexer helps make your signing process more secure and reliable — without slowing it down.

Success Story: How VirtualSignature-ID Streamlined Identity Checks Using Finexer

VirtualSignature-ID (VSID), a UK Government-accredited provider of digital signatures and identity verification, specialises in managing sensitive, high-value property transactions and Deed executions. VSID required a comprehensive solution to seamlessly handle electronic signatures, eWitnessing validation, automated AML checks (including PEPs & Sanctions), bank verification, and proof of funds assessments, along with the secure capability to initiate and control client-account fund transfers.

Integrating such diverse validation processes into one coherent workflow was challenging—especially ensuring smooth user experience without escalating costs or operational complexity.

By partnering with Finexer, VSID integrated FCA-compliant open banking directly into their platform. Finexer streamlined VSID’s entire transaction validation process, combining robust bank verification, automated AML screening, proof-of-funds validation, and controlled, secure payment initiation. As a result, VSID achieved faster, fully compliant property transactions, offering greater trust and efficiency to their legal and accountancy clients.

“Finexer provided exactly what we needed—easy integration, robust compliance, and responsive support. They understand our vision and have quickly become a trusted partner.”

David Kern, CEO, VirtualSignature-ID

Key Results of the Partnership:

• Faster AML & Identity Verification: Reduced time for identity checks and fund validation, significantly accelerating property transactions.
• Enhanced Client Experience: VSID now delivers a smoother, quicker onboarding process, exceeding client expectations for security and convenience.
• Integrated Fund Transfers: Securely initiate transfers directly into designated client accounts following thorough validation.

The Finexer and VirtualSignature-ID partnership demonstrates how combining electronic signatures with open banking verification can dramatically improve business processes—securely, quickly, and cost-effectively.
