Leasehold property is a common form of ownership in England and Wales, particularly in urban areas and commercial settings. When a leaseholder wishes to transfer their interest in a lease to another party, the legal mechanism used is known as a lease assignment. This process allows the incoming tenant to take over the lease on the same terms, subject to the landlord’s consent and other legal requirements.
At Blackstone Solicitors, we regularly advise clients on lease assignments for both residential and commercial properties. This article explains what lease assignment is, how it works, and the key legal considerations involved.

Understanding Leasehold Property
Before exploring lease assignment, it is important to understand the nature of leasehold property.
Leasehold ownership means that the tenant (or leaseholder) holds the right to occupy and use the property for a fixed period, as set out in the lease agreement. The freeholder (or landlord) retains ownership of the land and building. The lease will specify the duration, rent, service charges, rights, and obligations of both parties.
Leasehold interests can be bought and sold, but unlike freehold property, the transaction involves transferring the lease rather than the title to the land.
What Is Lease Assignment?
Lease assignment is the legal process by which a leaseholder transfers their lease to another person or entity. The assignee steps into the shoes of the original tenant and assumes all rights and responsibilities under the lease.
Key Features:
- The lease remains unchanged in terms of duration and conditions.
- The assignee becomes the new tenant.
- The assignor (original tenant) is released from their obligations, unless the lease or landlord requires otherwise.
- The landlord’s consent is usually required.
Lease assignment is distinct from subletting, where the original tenant retains responsibility and grants a separate tenancy to a subtenant.
When Is Lease Assignment Used?
Lease assignment is commonly used in the following scenarios:
- Sale of a Leasehold Property
A residential leaseholder selling their flat will assign the lease to the buyer.
- Business Transfer
A commercial tenant selling their business may assign the lease to the purchaser as part of the transaction.
- Exit from Lease Obligations
A tenant wishing to vacate the premises before the lease expires may assign the lease to a new tenant.
- Group Restructuring
Companies may assign leases between group entities for operational or tax reasons.
Legal Requirements for Lease Assignment
Lease assignment must comply with the terms of the lease and relevant legislation. The key legal requirements include:
- Landlord’s Consent
Most leases contain a clause requiring the landlord’s written consent before assignment. This is known as a qualified covenant against assignment.
The landlord must act reasonably and cannot withhold consent arbitrarily. However, they may impose conditions, such as:
- Approval of the assignee’s financial standing
- Payment of legal and administrative fees
- Execution of a deed of covenant by the assignee
- Licence to Assign
The landlord’s consent is usually documented in a formal licence to assign. This sets out the terms of the consent and any conditions imposed.
- Deed of Assignment
The actual transfer of the lease is effected by a deed of assignment. This legal document sets out the parties, the property, and the terms of the transfer.
- Registration
If the lease is registered at HM Land Registry (typically leases over seven years), the assignment must be registered. The assignee becomes the new registered proprietor.
Financial and Practical Considerations
Lease assignment involves various financial and practical considerations for both parties.
For the Assignor:
- Release from obligations: Subject to landlord approval, the assignor may be released from future liabilities.
- Costs: The assignor may be responsible for legal fees, landlord’s costs, and any outstanding rent or service charges.
- Timing: Assignments can take time, especially if landlord consent is delayed.
For the Assignee:
- Due diligence: The assignee should review the lease terms, service charge history, and any disputes or arrears.
- Financial checks: The landlord may require evidence of financial standing.
- Legal obligations: The assignee assumes all tenant obligations under the lease.
Restrictions and Conditions in Leases
Leases often contain restrictions on assignment, which must be carefully reviewed.
Common Restrictions:
- Absolute prohibition: Some leases prohibit assignment entirely. These are rare and may be challengeable.
- Qualified consent: Most leases require landlord consent, which must not be unreasonably withheld.
- Permitted assignments: Some leases allow assignment to group companies or specific parties without consent.
Conditions Imposed by Landlords:
- Rent deposit: The landlord may require a deposit from the assignee.
- Guarantor: A personal or corporate guarantor may be required.
- Deed of covenant: The assignee may need to enter into a deed confirming compliance with lease terms.
Legal advice is essential to interpret these clauses and negotiate appropriate terms.
Common Issues in Lease Assignment
Lease assignments can encounter various challenges, including:
- Delay in Landlord Consent
Landlords may take time to review the assignee’s credentials or impose onerous conditions.
- Disputes Over Service Charges
Outstanding service charges or disputes with the freeholder can complicate the transaction.
- Unclear Lease Terms
Ambiguities in the lease may lead to disagreements over assignment rights or obligations.
- Unregistered Leases
Older or short leases may not be registered, requiring additional steps to prove title.
At Blackstone Solicitors, we help clients navigate these issues and ensure a smooth assignment process.
Tax and Regulatory Implications
Lease assignment may have tax and regulatory consequences, depending on the nature of the transaction.
Stamp Duty Land Tax (SDLT)
SDLT may be payable by the assignee, depending on the premium paid and the rent. Residential and commercial rates differ, and reliefs may apply.
VAT
If the property is opted to tax, VAT may be payable on the assignment. Legal advice is essential to ensure correct treatment.
Regulatory Compliance
Commercial assignments may involve regulatory considerations, such as planning use classes or licensing requirements.
