An Authorised Guarantee Agreement (AGA) is the statutory guarantee given by an Outgoing Tenant when assigning a "new" commercial lease — one granted on or after 1 January 1996 in England & Wales or Northern Ireland — where the Landlord conditions its consent to assignment on the Outgoing Tenant guaranteeing the Incoming Tenant's performance. Use our free UK AGA template to give the precise statutory guarantee permitted by section 16 of the Landlord and Tenant (Covenants) Act 1995 — covering the s.16(4) limits that prevent over-reaching (no binding after the Incoming Tenant is itself released; no sub-guarantee following Good Harvest Partnership v Centaur Services [2010] EWHC 330 (Ch)) and the s.16(5) permitted content (primary obligation, joint and several liability, covenant to take a new lease if the lease is forfeited or disclaimed). The AGA is executed as a deed and triggers the s.17 six-month landlord notification window for any recovery from the Outgoing Tenant.

An Authorised Guarantee Agreement (AGA) is the statutory form of guarantee that an Outgoing Tenant gives the Landlord on assigning a UK commercial lease — covering the assignee Tenant's performance of the tenant covenants in the lease. The AGA replaces the open-ended privity-of-contract liability that applied to leases granted before 1996, under which an original tenant remained on the hook for rent and other tenant covenants for the entire term of the lease regardless of how many times the lease had been assigned. From 1 January 1996, the Landlord and Tenant (Covenants) Act 1995 (LTCA 1995) released the original tenant on assignment (s.5) but allowed the Landlord to require the Outgoing Tenant to give an AGA under s.16 as a precondition of consent.
An AGA only operates for "new tenancies" granted on or after 1 January 1996 in England & Wales and Northern Ireland (Scotland has its own distinct commercial leasing regime and does not use AGAs). The form and content of the AGA is tightly constrained by statute: section 16(4) LTCA 1995 prohibits the AGA from binding the Outgoing Tenant after the Incoming Tenant is itself released on a further assignment (so the Outgoing Tenant guarantees only the IMMEDIATE assignee, not the assignee's assignee), and prohibits it from binding anyone other than the Outgoing Tenant (so a sub-guarantee from a third party is unenforceable — Good Harvest Partnership LLP v Centaur Services Ltd [2010] EWHC 330 (Ch)). Section 16(5) sets out what the AGA MAY contain: a primary obligation (the Outgoing Tenant promises performance directly, not just as a secondary guarantor), joint and several liability with the Incoming Tenant, and a covenant to take a new lease on the same terms if the original lease is forfeited or disclaimed on the Incoming Tenant's insolvency.
AGAs are MANDATORY for landlord consent in many commercial assignments under the Landlord and Tenant Act 1927 s.19(1A) — which permits a Landlord of a commercial lease granted on or after 1 January 1996 to withhold consent to assignment on conditions agreed in the lease, almost always including the giving of an AGA. The practical effect for UK commercial Tenants: the Outgoing Tenant's contractual exit from a lease through assignment is not a clean break — they remain economically on the hook for the Incoming Tenant's performance for as long as the Incoming Tenant holds the lease, subject only to the s.17 six-month landlord notification window for any fixed-charge recovery and the s.16(4) statutory ceiling on the period of guarantee.
This UK AGA template covers the full statutory architecture of section 16 LTCA 1995, with a Free baseline for the simple guarantee and an Expert tier covering the s.16(5) permitted content and s.17 protective limits.
Outgoing Tenant, Incoming Tenant and Landlord with Companies House numbers, registered offices and named signatories.
Date of grant, term, premises description and address — confirming the lease is "new" (granted on or after 1 January 1996) and therefore within the LTCA 1995 regime.
Date of assignment and annual rent payable under the Original Lease — anchors the AGA to the specific transaction.
All tenant covenants under the Original Lease (UK Landlord standard) or specified covenants only (Outgoing Tenant-favoured for high-value or specialised covenants).
England and Wales or Northern Ireland with matching exclusive jurisdiction — Scotland excluded (different commercial leasing regime).
Express restatement of the protective limits — AGA cannot bind after Incoming Tenant is released on further assignment; AGA binds only the Outgoing Tenant (no sub-guarantee per Good Harvest v Centaur).
Outgoing Tenant covenants performance directly, not just as secondary guarantor — permitted by s.16(5)(a) and confirmed enforceable in K/S Victoria Street v House of Fraser [2011] EWCA Civ 904.
Outgoing Tenant and Incoming Tenant jointly and severally liable for the tenant covenants — Landlord may pursue either or both.
Outgoing Tenant covenants to take a new lease on the same terms if the Original Lease is forfeited following Incoming Tenant default.
Outgoing Tenant covenants to take a new lease if the Original Lease is disclaimed by an Incoming Tenant insolvency office-holder or trustee in bankruptcy.
The new lease takes effect for the unexpired residue of the Original Lease term — typically the s.16(5) maximum.
Express restatement of the Landlord's obligation to serve a section 17 notice within six months of any fixed-charge liability arising — failure to serve releases the Outgoing Tenant.
Time within which the Outgoing Tenant must pay following demand under a s.17 notice; interest on unpaid sums at the rate in the Original Lease.
Landlord's legal costs of any enforcement action against the Outgoing Tenant — typically on an indemnity basis.
Outgoing Tenant indemnity against any third-party claim arising from the assignment, where the Outgoing Tenant has structured the assignment to defeat the Landlord's rights.
Executed as a deed under s.44 Companies Act 2006 (corporate) or s.1 Law of Property (Miscellaneous Provisions) Act 1989 (individual) — necessary because the AGA is gratuitous from the Outgoing Tenant's perspective.
Permitted execution in counterparts — practical for multi-party three-way signature flows.
eIDAS-compliant electronic signing under Law Commission 2019 guidance and case law — accepted for deeds where formalities followed.
Assignment of a registered leasehold estate is registrable at HM Land Registry; the AGA is noted against the Landlord's title where appropriate.
Detailed cross-reference back to the Original Lease tenant covenants — the AGA picks up everything the assignee Tenant must do under the lease.
Follow these steps to give a UK statutory AGA on assignment of a commercial lease.
Check the Original Lease was granted on or after 1 January 1996. AGAs only apply to "new tenancies" under LTCA 1995 — older leases continue under the privity-of-contract regime.
Provide the Outgoing Tenant (giving the AGA), Incoming Tenant (assignee) and Landlord with addresses, Companies House numbers and named signatories.
Insert the date of grant, term, premises description, address and annual rent of the Original Lease — these anchor the AGA to the specific transaction.
Enter the date of the assignment — the AGA takes effect from this date.
Choose all tenant covenants under the Original Lease (UK Landlord standard) or specified covenants only (Outgoing Tenant-favoured).
Tick the express restatement of the s.16(4) protective limits — AGA cannot bind after further assignment; no sub-guarantee.
Tick primary obligation, joint and several liability, new lease covenant on forfeiture and on disclaimer. Set the maximum new lease term (typically the unexpired residue).
Tick the express restatement of the Landlord's obligation to serve a s.17 notice within six months of any fixed-charge liability arising.
Tick Landlord costs of recovery and (if applicable) third-party indemnity against assignment-defeating structures.

UK AGAs sit at the precise intersection of the Landlord and Tenant (Covenants) Act 1995 (release and guarantee), the Landlord and Tenant Act 1927 (assignment consent), the Law of Property Act 1925, and the deed-execution formalities under the Companies Act 2006 and Law of Property (Miscellaneous Provisions) Act 1989. Each must be addressed correctly or the AGA risks being void as exceeding the s.25 anti-avoidance limits or unenforceable through defective execution.
This template is for informational purposes only and does not constitute legal advice. UK commercial lease assignments and AGAs are highly specialised — for any lease with annual rent above £50,000, any lease of premises above 1,000 square metres, any group reorganisation assignment, or any lease with sub-letting or sub-guarantee structures, professional legal advice from real estate counsel is strongly recommended.

Section 5 of the Landlord and Tenant (Covenants) Act 1995 releases the assigning tenant from the tenant covenants of the lease on assignment of a "new tenancy" — a tenancy granted on or after 1 January 1996. This reversed the privity-of-contract rule under which an original tenant remained liable for the entire term of the lease regardless of subsequent assignments. Section 16 then permits the Landlord to require the assigning tenant to give an Authorised Guarantee Agreement under which the Outgoing Tenant guarantees the IMMEDIATE assignee's performance — not the assignee's assignee, and not anyone other than the Outgoing Tenant. The combined effect is a single-step economic liability chain: the Outgoing Tenant remains on the hook until the Incoming Tenant itself assigns onwards.
Section 16(4) LTCA 1995 sets out the protective limits on AGA content: paragraph (a), the AGA must not bind the Outgoing Tenant after the Incoming Tenant is itself released on a further assignment; paragraph (b), the AGA must not bind any other person (i.e. a sub-guarantee from a third party is unenforceable). Good Harvest Partnership LLP v Centaur Services Ltd [2010] EWHC 330 (Ch) confirmed that a sub-guarantee given by a director of the Outgoing Tenant (in an attempt to secure a chain of guarantees through subsequent assignments) is void under s.16(4)(b) — a Landlord cannot drag third parties into the AGA chain. K/S Victoria Street v House of Fraser (Stores Management) Ltd [2011] EWCA Civ 904 confirmed that the s.16(5) permitted-content list is exhaustive but generous — primary obligation drafting per s.16(5)(a) is valid.
Section 17 LTCA 1995 imposes a strict procedural condition on any landlord recovery of a fixed charge (rent, service charge, insurance rent, interest) from the Outgoing Tenant under an AGA. The Landlord must serve a section 17 notice on the Outgoing Tenant within SIX MONTHS of the fixed charge becoming due. If the Landlord fails to serve a s.17 notice within the six-month window, the Outgoing Tenant is released from liability for that fixed charge in full. The notice must specify the nature of the charge, the amount, and that the Landlord intends to recover from the Outgoing Tenant. The six-month deadline runs separately for each instalment of rent and is the single most important protective limit on Outgoing Tenant exposure under an AGA.
Section 19(1A) of the Landlord and Tenant Act 1927 (inserted by LTCA 1995 s.22) permits a Landlord of a commercial lease granted on or after 1 January 1996 to withhold consent to assignment on conditions agreed in the lease — almost always including the requirement that the Outgoing Tenant give an AGA. This contrasts with the general s.19(1) reasonableness test for residential and pre-1996 commercial leases. The practical effect: where the Original Lease contains an AGA-consent condition (and most modern UK commercial leases do), the Landlord is entitled to require an AGA without any further reasonableness scrutiny. The Outgoing Tenant cannot avoid the AGA by arguing the Landlord is being unreasonable — the lease itself has predetermined that an AGA is reasonable in the parties' eyes.
Section 16(5) LTCA 1995 sets out the matters that an AGA may permissibly cover. Paragraph (a) permits the Outgoing Tenant to give a primary obligation — promising performance directly rather than just as a secondary guarantor (K/S Victoria Street confirms this is valid and not a disguised privity-of-contract revival). Paragraph (b) permits joint and several liability with the Incoming Tenant. Paragraph (c) permits a covenant by the Outgoing Tenant to take a new lease on substantially the same terms if the Original Lease is forfeited by the Landlord or disclaimed by an Incoming Tenant insolvency office-holder or trustee in bankruptcy. The new lease covenant is the most commercially significant of the s.16(5) permissions — it gives the Landlord a fallback tenant on the same terms if the chain breaks.
Section 25 LTCA 1995 voids any agreement that purports to exclude, modify or frustrate the operation of the Act — in particular, the s.5 release and the s.16(4) limits. EMI Group Ltd v O&H Q1 Ltd [2016] EWHC 529 (Ch) addressed a structural attempt to defeat the s.25 anti-avoidance regime by assigning the lease back to the original tenant. The court held that such an assignment back is void where it is structured to revive privity-of-contract liability that LTCA 1995 had released. The implication for AGA drafting: the AGA must operate exactly within the s.16 statutory envelope — any attempt to extend the guarantee beyond the immediate assignee, or to drag in third parties, or to revive original-tenant liability after release, is void under s.25.
