Navigating the Complexities of Assignments and Sharing in Phone Mast Leases Under the Electronic Communications Code (2024)

by | 30 Apr 2024 | Advice

In the intricate landscape of phone mast leases, certain clauses hold significant weight, dictating the extent to which operators can assign or share their rights with third parties. These clauses often evoke questions and uncertainties, especially among landlords who may not be well-versed in the nuances of telecom leases.

In this blog, we’ll delve into the concepts of assignments and sharing, shedding light on their implications and how they intersect with the evolving framework of the Electronics Communication Code Rights in the UK (the Code).

Assignments: Passing the Baton

Assignments in phone mast leases refer to the transfer of rights and responsibilities from one party (the tenant/operator) to another. This could involve the tenant relinquishing control over the mast site to a different operator or entity. The terms surrounding assignments vary, with leases typically stipulating whether assignments are permissible, the conditions for approval (if required), and any associated premium payments.

Key Considerations

Consent Requirement: Many leases mandate that assignments must be approved by the landlord (not to be unreasonably denied). This ensures that the new operator meets certain criteria and aligns with the landlord’s interests.Premium Payments: Some leases necessitate the payment of a premium to the landlord upon assignment. This compensates the landlord for the transfer of rights and potential changes to the property’s use.Restrictions on Assignees: In certain cases, operators may only be allowed to assign to specific entities, such as group companies. This limitation aims to maintain control over who operates the mast and ensures alignment with the landlord’s preferences.

Complexities of assignments and sharing in phone mast leases under the electronic communications code

Sharing: Collaboration or Complication?

Sharing provisions in phone mast leases allow operators to co-locate their equipment on a single mast site, often referred to as site sharing or code sharing. This arrangement can be mutually beneficial, enabling operators to reduce costs and optimise network coverage. Similar to assignments, the terms governing sharing vary and can impact the landlord’s rights and obligations.

Key Considerations

Landlord’s Consent: Lease agreements typically specify whether sharing requires the landlord’s consent (not to be unreasonably denied). This ensures that the landlord remains informed and can assess any potential impacts on their property.

Premium Payments: Depending on the lease terms, landlords may be entitled to receive additional payments from operators engaging in sharing arrangements. This compensates for the increased use of the property and any associated wear and tear.

Code Operators: In some cases, leases restrict sharing to code operators, ensuring that only licensed operators can access the mast site. This safeguards against unauthorised use and maintains compliance with regulatory requirements.

Aligning with the Electronics Communication Code Rights

The emergence of the Electronics Communication Code in the UK has introduced a new framework for governing telecom leases. Under this Code, operators are now able to share existing equipment on site for free. This significant change impacts the dynamics of sharing provisions in leases completed after 2017.

Implications for Landlords

Automatic Rights: Leases completed after 2017 grant operators the automatic right to share existing equipment on site without the need for specific lease provisions.

Potential Nullification: Restrictive site sharing clauses in pre-2017 leases could render the agreement null and void due to non-compliance with the Code.

Additional Considerations for New Phone Mast Leases

In new leases, landlords should consider incorporating an Authorised Guarantee Agreement (AGA) for assignments. This agreement ensures that the original tenant remains liable for the performance of the lease obligations, providing added security for the landlord in case of assignment.


Assignments and sharing clauses in phone mast leases represent critical aspects that can impact both operators and landlords. By understanding the implications of these clauses and their alignment with the Electronics Communication Code Rights, landlords can navigate telecom leases more effectively and safeguard their interests. As the telecom landscape continues to evolve, staying informed and proactive is key to ensuring mutually beneficial lease agreements for all parties involved.
