What Is a Concurrent Lease?

A concurrent lease is granted by a landlord out of their own reversion while an existing lease of the same premises is already in place. The concurrent lessee steps into the position of the immediate landlord — collecting the existing tenant's rent and performing the head landlord's obligations. The existing tenant's occupation is unaffected; only their immediate landlord changes.

Commercial Uses

Concurrent leases arise in: sale and leaseback (freeholder grants concurrent lease to investor who collects profit rent); mezzanine finance (lender takes concurrent lease as security — on default, the lender enforces the lease and collects rent directly from the sitting tenant); profit rent investment; leasehold enfranchisement structures (subject to LRHUDA 1993 scrutiny and LFRA 2024 reforms).

LTA 1954 — Concurrent Lessee as Competent Landlord

The concurrent lessee becomes the competent landlord under LTA 1954 s.44 for commercial tenancies. The concurrent lessee must deal with all s.25 notices and s.26 requests. Ground (g) (own occupation) is only available if the concurrent lessee genuinely intends to occupy. Careful timing of concurrent lease terms and LTA 1954 notices is essential.

Forfeiture and Practical Risks

Forfeiture of the concurrent lease by the freeholder ends the concurrent lessee's interest. The concurrent lessee has relief from forfeiture rights (LPA 1925 s.146). The primary commercial risk is the existing tenant's insolvency — the concurrent lessee must pay the head rent regardless of whether the existing tenant pays. A rent deposit from the existing tenant and rent suspension provisions in the concurrent lease are essential protections.

Frequently asked questions

What is a concurrent lease?+

A concurrent lease (or reversionary lease) is a lease granted by a landlord out of their own interest while an existing lease of the same property is already in place. The concurrent lessee becomes the immediate landlord of the existing tenant — collecting the existing tenant's rent and performing the head landlord's obligations — while the freeholder collects a lower head rent from the concurrent lessee.

How does a concurrent lease differ from subletting?+

In a subletting (underlease), the existing tenant grants a new lease out of their own leasehold interest. In a concurrent lease, the landlord grants a lease out of their own reversion while the existing tenant remains in occupation. The existing tenant is unaffected — only their immediate landlord changes.

Does the existing tenant need to consent to a concurrent lease?+

No. The existing tenant does not consent to the grant of a concurrent lease. However, the existing tenant must be notified of the change of landlord (s.3 LTA 1985; s.48 LTA 1987). The concurrent lessee must serve a s.48 notice providing an England and Wales address for service — until this is done, the existing tenant's rent is not lawfully due.

Commercial Lease Law
Section 25 Notice UK — LTA 1954 Landlord Termination Guide
A section 25 notice is the formal notice by which a commercial landlord terminates a business tenancy protected by the Landlord and Tenant Act 1954 (LTA 1954) and either proposes terms for a new tenancy or opposes renewal on a statutory ground. Key features: served between 6 and 12 months before the proposed termination date; Form 1 (hostile — opposing renewal) or Form 2 (friendly — proposing new tenancy terms). Grounds of opposition (s.30(1)): (a) breach of repair; (b) persistent delay in rent; (c) other substantial breach; (d) alternative accommodation; (e) uneconomic sub-tenancy of whole; (f) intention to demolish or reconstruct (genuine, firm, settled intention required at date of notice and trial); (g) own occupation (14-month ownership required). Tenant's response: court application within 4 months of s.25 notice or right to new tenancy lost; deadline can be extended by written agreement under s.29B LTA 1954. Compensation (ss.37, 37A): where renewal opposed on grounds (e), (f) or (g) and landlord succeeds — rateable value; double rateable value if tenant occupied 14+ years. Interim rent (ss.24A-24D LTA 1954): either party can apply; runs from earliest possible termination date in s.25 notice. Scotland: LTA 1954 does not apply — tacit relocation governs commercial lease renewal.
Mortgage & Finance Law
LPA Receiver UK — Law of Property Act 1925 Receiver and Buy-to-Let Landlords
An LPA receiver (Law of Property Act receiver or fixed charge receiver) is a property professional appointed by a mortgagee (lender) under LPA 1925 ss.101–109 without a court order when a borrower defaults on a mortgage. The receiver is deemed by statute to be the agent of the mortgagor (LPA 1925 s.109(2)) — meaning the lender is not liable for the receiver's acts. Statutory powers (s.109(3)): collect rents and income; grant/accept surrender of leases up to 21 years; insure; repair — usually supplemented by express contractual powers. Power arises when: mortgage is by deed; mortgage money is due; and the power is exercisable (s.103): one month's notice served; or interest is two months in arrears; or another mortgage covenant is in breach. Impact on existing tenancies: existing ASTs and tenancy agreements continue and bind the receiver; tenants redirect rent to the receiver; the receiver steps into the landlord's shoes to manage, enforce covenants, serve notices, and take possession; all statutory landlord duties (gas safety; EICR; deposit protection; Renters' Rights Act 2025) apply to the receiver. Landlord in default: loss of rent (all rents belong to the receiver from appointment); loss of management control; no automatic possession (receiver must take possession proceedings for vacant possession); sale by receiver under power of sale in mortgage deed; duty of care to obtain proper market value (Silven Properties v Royal Bank of Scotland [2003] CA). Corporate borrowers: registration at Companies House within 7 days required (Companies Act 2006 s.859A); agency terminates on winding-up or administration. MCOB compliance: regulated lenders must follow FCA MCOB 13 before enforcement.

Underlease UK
Underleases (sub-leases): obtaining consent to underlet (LTA 1988), the fundamental rule that the underlease cannot exceed the head lease, intermediate landlord obligations, LTA 1954 security of tenure for commercial undertenants (including the s.65 risk), forfeiture of the head lease, and the intermediate landlord's trapped position.
