Electronic signatures for tenancy agreements in the UK

Landlords and letting agents sign more documents than almost any other small business: the tenancy agreement itself, inventories, deposit paperwork, guarantor agreements, renewals and notices. This guide explains when an electronic signature works for each, where a deed or a witness is still required, what changed with the Renters' Rights Act 2025, and a practical workflow for getting a tenancy signed in a day without a printer. It covers England primarily, with notes on Wales, Scotland and Northern Ireland.

The short answer

• An ordinary residential tenancy agreement can be signed electronically. A lease for three years or less taking effect in possession at a market rent does not need to be a deed (Law of Property Act 1925, s 54(2)), so it needs no witness, and the general rule that a signature is not invalid for being electronic applies.
• Longer leases, and anything that must be a deed, are different. Deeds need a witness physically present, and leases over seven years need Land Registry registration with the registry's own signature rules.
• Guarantor agreements are often drafted as deeds; if yours is, it needs a witness and should not go through an ordinary e-signature flow.
• Serving documents is a separate question from signing them. Deposit information, the gas safety certificate, the EPC and the government's tenant guidance must be given to the tenant on time; a signing tool helps evidence that, but check the current rules.

Why a tenancy agreement can be e-signed

Three rules combine. First, under section 54(2) of the Law of Property Act 1925, "leases taking effect in possession for a term not exceeding three years ... at the best rent which can be reasonably obtained without taking a fine" can be created without a deed; in fact they need no writing at all, though every sensible landlord uses a written agreement. Second, the Electronic Communications Act 2000 and the retained eIDAS Regulation mean an electronic signature on that written agreement is admissible and cannot be refused effect merely for being electronic. Third, the Law Commission's 2019 report confirmed that an electronic signature can validly execute a document where the signer intends to authenticate it and any formalities are met; for a short residential tenancy there are no extra formalities.

So a 12-month assured tenancy signed by landlord and tenant through a signing tool, with a consent record, a timestamped audit trail and a hashed final PDF, is as effective as the same agreement signed in ink, and better evidenced. Our legal-validity page has the statutory detail.

The Renters' Rights Act 2025

The Renters' Rights Act 2025 received Royal Assent on 27 October 2025 and its first phase took effect on 1 May 2026. From that date, new private tenancies in England are periodic assured tenancies rather than fixed-term assured shorthold tenancies, existing ASTs converted automatically, and section 21 "no-fault" notices were abolished. The Act also changed the documents landlords must give tenants and the government withdrew the old "How to rent" guide on the same day.

For signing, this changes the content of the agreement more than the method: a periodic assured tenancy is still a short lease and can still be signed electronically. It does mean that any template you built before May 2026 needs reviewing, and that you should take the written-statement and information requirements from current GOV.UK guidance rather than from older checklists. If you use AiresDocs templates, update the PDF and the template together.

When a deed is needed

A deed must be signed by the individual "in the presence of a witness who attests the signature" and delivered (Law of Property (Miscellaneous Provisions) Act 1989, s 1(3)); a company signs under section 44 of the Companies Act 2006 (two authorised signatories, or a director with a witness). The Law Commission concluded that the witness must be physically present; watching over a video call does not satisfy the requirement under current law. HM Land Registry takes the same position and, for deeds it registers, accepts only conveyancer-certified electronic signatures (witness present, one-time code by text, platform audit report retained) or qualified electronic signatures.

In lettings, deeds appear in a few places:

• Leases over three years (and any lease that is not at a market rent or does not take effect immediately) must be made by deed. Leases over seven years must also be registered.
• Deeds of variation or surrender of a lease.
• Guarantor agreements drafted as deeds (see below).
• Some agreements for lease in commercial lettings.

AiresDocs does not provide a witness workflow. For these documents, sign on paper with a witness, or use a conveyancer's process that meets practice guide 82.

Guarantors

A guarantee must be in writing and signed by the guarantor (Statute of Frauds 1677, s 4). Many guarantor agreements are drafted as deeds so that the landlord does not have to show consideration moving to the guarantor; if yours says "executed as a deed" or has a witness block, treat it as a deed and get it witnessed in person. If it is drafted as a simple contract supported by consideration (for example, the landlord granting the tenancy in reliance on the guarantee), it can be signed electronically like the tenancy. Ask whoever drafted your template which it is, and keep the guarantor's signing event separate from the tenant's: their own invitation, their own email address, ideally an access code given by phone, since guarantors are the party most likely to dispute later that they signed.

The paperwork around the agreement

Several documents must be given to the tenant, and the audit trail is a good way to evidence that they were. The usual list in England:

Scotland, Wales and Northern Ireland

Scotland uses the private residential tenancy under the Private Housing (Tenancies) (Scotland) Act 2016, with a model agreement and statutory notes. Scots law on electronic documents is in the Requirements of Writing (Scotland) Act 1995 as amended, which recognises electronic signatures and sets its own rules for when an electronic document is self-proving. An ordinary PRT can be signed electronically. Wales replaced tenancies with occupation contracts under the Renting Homes (Wales) Act 2016, which requires a written statement of the contract within 14 days; signing is governed by the same England-and-Wales law of signatures. Northern Ireland has its own Private Tenancies legislation with a required tenancy information notice; the law of deeds and electronic signatures is similar to England's. In each case the short-lease principle holds: ordinary residential tenancies are not deeds and can be e-signed, while deeds need a witness.

A landlord's signing workflow

1. Prepare the pack as one PDF. Tenancy agreement, then the deposit prescribed information, then any acknowledgements. One document, one signing session, one certificate.
2. Save it as a template with roles "Landlord", "Tenant 1", "Tenant 2" and "Guarantor" if used (not for deed-style guarantees). Place signature fields on the agreement, initials on key clauses if you like, and "received" checkboxes on the information pages.
3. Create the document from the template, type the names and email addresses, choose sequential signing (tenants first, you last) so you countersign only after they have committed, and set an expiry of a few days to keep the process moving.
4. Send. Each tenant signs from their phone; you sign last. Everyone receives the completed PDF with the certificate.
5. Protect the deposit and record the dates from the certificate in your tenancy register.

Keeping the evidence

A tenancy may be examined years later in a possession claim or a deposit dispute. Keep the sealed PDF with its certificate, the completion email, and a note of the document ID. Export your documents and audit JSON periodically. If a tenant later disputes a term, the hash of the original upload shows exactly which text they were shown; if they dispute signing at all, the trail shows the address, time, device and consent. Read audit trails explained for how to work through it, and how to verify a signed contract for the mechanics.
