by | 28 Aug 2023 | Informative


As a specialist telecoms surveyor company, The Phone Mast Advice Company is committed to helping landlords across the UK navigate the complex world of phone mast leases. We understand that the vast array of terminology used by phone mast operators and industry professionals can be overwhelming and challenging to grasp. In this blog post, we aim to demystify the jargon frequently encountered in Heads of Terms and Lease Agreements for phone masts. By gaining a better understanding of these terms, landlords can make informed decisions and protect their interests effectively.

Heads of Terms (HoT)

Heads of Terms form the foundation of negotiations between the landlord and the phone mast operator. These are non-legally binding documents outlining the key commercial points of the lease agreement. Common terms include:

  1. Rent (Initial Rent and Rent Reviews): The amount the operator will pay the landlord for the use of their land. Rent reviews indicate how and when the rent will be adjusted in the future to account for inflation or other factors.
  2. Term of Agreement: The length of time the lease will be in effect. Typically, this ranges from 10 to 25 years
  3. Site Sharing: This clause indicates whether the operator can share the site with other telecom providers, potentially affecting the rent and the site’s capacity.
  4. Break Clause: A provision allowing either party to terminate the lease before the expiration of the term under specific conditions.
  5. Mast Sale (Premium Lease Payments): Also known as “premium lease payments,” this term refers to a lump sum payment made by the phone mast operator to the landlord for the leasehold or ownership of the lease of the mast itself, not the piece of land it sits on. It provides an immediate financial benefit to the landlord and is agreed upon during negotiations.

Lease Agreement

Once the Heads of Terms are agreed upon, they form the basis for the legally binding Lease Agreement. Some key terms that landlords should be familiar with include:

  1. Permitted Use: Specifies the purposes for which the operator can use the site for telecom equipment installation.
  2. Access Rights: Outlines the operator’s rights to access the site for installation, maintenance, and repair of telecom equipment.
  3. Insurance and Liability: Details the responsibilities of both parties regarding insurance coverage and liability for damages or accidents.
  4. Upgrades and Alterations: Clarifies how and when the operator can modify or upgrade their equipment on the site.
  5. Rent Review Mechanism: The process and frequency of rent adjustments based on predefined criteria.
  6. Open Market Value (OMV): The Open Market Value refers to the rental value that the site would achieve if it were available for letting on the open market, assuming both parties are willing and not under any compulsion to proceed. OMV serves as a benchmark for determining a fair and competitive rent during rent reviews.
  7. Retail Price Index (RPI): RPI is a measure of inflation used to adjust the rent periodically during the lease term. The RPI figure indicates the percentage increase in the general level of prices for goods and services in the UK. It helps ensure that the rent keeps up with inflation, protecting both the landlord and the operator from the eroding effects of rising costs.

Wayleave Agreement

A Wayleave Agreement is different from a lease agreement and is usually required when the telecom equipment is installed on private land. Key terms in this agreement include:

  1. Easement: A legal right granted by the landowner to the operator, allowing them to use the land for specific purposes without transferring ownership.
  2. Wayleave Fee: The compensation paid to the landlord for granting the easement.


Understanding the terminology used by phone mast operators and industry professionals is crucial for landlords who have phone masts on their land. By grasping the key terms in Heads of Terms and Lease Agreements, landlords can ensure fair agreements, protect their rights, and make informed decisions about their properties.
