Phone Mast Lease: What UK Landlords Need to Know in 2026
What a phone mast lease is, the clauses it contains, how long it lasts, what happens when it expires, what the operator may do without asking, what changed on 7 April 2026, and the mistakes to avoid before you sign.
Written by Matt Restall, founder, specialist telecoms surveyor. Last reviewed 19 October 2026.
In short
A phone mast lease is a commercial lease with one big difference: the operator holds statutory rights under the Electronic Communications Code that override many of the clauses. The lease does not end when the term expires, the operator can usually upgrade and share without consent, restrictions on assignment are void, and the Tribunal can impose terms. Since 7 April 2026 even legacy leases renewing under the Landlord and Tenant Act 1954 are valued on the Code basis. The money side is covered in our phone mast rent guide; the practical next step is a free lease check.
What is a phone mast lease?
A phone mast lease is a legal contract that grants an operator exclusive possession of land or part of a building for a period of time, fixed or periodic, in return for rent (called consideration under the Code). Not all phone mast agreements are leases: some are structured as licences or wayleaves, which do not grant exclusive possession. The distinction matters because the rights and protections available to both landlord and operator differ depending on the type of agreement.
In essence a phone mast lease is very similar to a normal commercial lease for a shop or an industrial unit. The exception is that the tenant benefits from “code powers” under the Electronic Communications Code, set out in Schedule 3A to the Communications Act 2003 (inserted by the Digital Economy Act 2017), which replaced the old code in the Telecommunications Act 1984 on 28 December 2017. Those powers sit above the contract: several clauses a landlord would expect to rely on are overridden or void.
Until 28 December 2017, phone mast leases were given security of tenure under Part II of the Landlord and Tenant Act 1954. Leases granted before that date and protected by the 1954 Act are still renewed under that Act. Leases granted after it are not protected by the 1954 Act; instead the Code gives operators their own form of security of tenure, with no option for the landlord to contract out.
What clauses does a phone mast lease contain?
These are the standard clauses and provisions you would expect to find, and what each one does:
- Date and parties
- When the lease was granted, and who the lessor (landlord) and lessee (operator) are.
- Premises
- The exact area the operator has exclusive possession of: the compound or the roof area, with a plan.
- Term and commencement date
- How long the lease runs and from when; the commencement date can differ from the date of the document.
- Rent
- What the operator pays, normally annually. Under the Code it is called consideration.
- Permitted use
- Normally restricted to telecommunications.
- The rights and equipment rights
- What the operator may install, maintain and upgrade on the site.
- Sharing and assignment
- The operator's rights to share the site with other operators and to assign the lease. Both changed under the 2017 Code: restrictions are largely void.
- Group companies
- Whether companies in the operator's group may benefit from the lease.
- Rent review and review dates
- The method (often the higher of market value or an index such as RPI) and the frequency, typically every three to five years.
- Tenant and landlord break clauses
- The dates and the procedure for either side to end the lease early.
- Lift and shift
- The right to require equipment to be moved or removed for essential repairs or works, and who pays.
- Access and emergency access
- The route to the site, notice for routine visits, and the procedure in an emergency.
- Switch off
- How the equipment is powered down in an emergency or during works.
- Insurance and indemnity
- Who insures what, and the process if there is a claim.
- Yield up and reinstatement
- What the operator must remove and restore when the lease ends (Paragraph 40 of the Code).
- Wayleaves and easements
- The landlord's obligations to allow third parties to install power and communication links to the site.
What are heads of terms, and why do they matter?
Heads of Terms are the main points of the lease, negotiated between the landlord’s and the operator’s surveyors before solicitors are instructed. Agreeing good Heads of Terms in principle first saves both sides time and legal fees, because the solicitors then document what has been agreed rather than negotiating it.
Draft Heads of Terms arrive from the operator’s advisers and represent their opening position. They should be negotiated by a specialist telecoms surveyor so that the wording, and the protections it gives you, are right before the lease is drafted. See phone mast solicitors or surveyors: who you need, and when.
What does the Electronic Communications Code let the operator do?
The Code grants Ofcom-registered operators statutory rights to install, maintain, upgrade and share telecommunications apparatus on private land. What makes it significant for landowners is that it gives operators the power to apply to the Tribunal (in England and Wales, the First-tier Tribunal (Property Chamber) or the Upper Tribunal (Lands Chamber)) to have an agreement imposed on an unwilling site provider. Under Paragraph 21, the Tribunal will impose an agreement if the prejudice to the site provider is capable of being adequately compensated in money and the public benefit of the installation outweighs that prejudice. In practice, operators almost always satisfy this test.
The redevelopment defence: Paragraph 21(5)
The principal defence available to landowners is the redevelopment ground: if you can demonstrate a firm, settled and unconditional intention to redevelop your land, and a reasonable prospect of carrying it out, the Tribunal may refuse the operator’s application. This test was confirmed in EE Ltd v Sir James Chichester [2019] UKUT 164 (LC) and applied more recently in CTIL v Firoka (Kings Cross) Ltd (2025), where a hotel owner defeated a rooftop installation application on genuine redevelopment grounds.
How long does a phone mast lease last, and can it be ended early?
Duration and break clauses
The Code prescribes no minimum or maximum duration. In practice the Tribunal typically imposes a 10-year term with break clauses. EE Ltd & Hutchison 3G UK Ltd v AP Wireless II (UK) Ltd [2024] UKUT 216 (LC) (Vache Farm) set the current standard: a 10-year lease with a tenant break at year 5 and a landlord’s redevelopment break exercisable on or after the fifth anniversary on 18 months’ notice. The Tribunal confirmed that the landlord’s right to terminate is not limited to non-telecoms redevelopment.
What happens when a phone mast lease expires?
Continuation after expiry: Paragraphs 30 and 31
Paragraph 30 provides that a phone mast lease does not end when the contractual term expires. It continues in force as a matter of statute until actively determined under the Code. Simply waiting for the lease to run out does not remove the operator from your land.
To end a lease, the site provider must serve a Paragraph 31 noticegiving at least 18 months’ notice and specifying one of four statutory grounds: substantial breach, persistent payment delays, intention to redevelop, or that the Paragraph 21 public benefit test is no longer met. If the operator serves a counter-notice within three months, the agreement continues until the Tribunal determines the matter.
If the operator wants a new agreement instead, it serves a Paragraph 33 notice, or for a 1954 Act lease a Section 26 request: see our Section 26 notice guide and the renewal letter explainer.
Can the operator upgrade, share or assign the lease without my consent?
Upgrading and sharing: Paragraph 17
Under Paragraph 17, an operator may upgrade apparatus or share it with another operator without the landowner’s consent, provided the changes have no more than a minimal adverse impact on the appearance of the apparatus and impose no additional burden on the site provider. The Product Security and Telecommunications Infrastructure Act 2022 strengthened these rights: Section 58 inserted Paragraph 17A, extending automatic upgrading and sharing rights to legacy agreements pre-dating 2017, subject to 21 days’ notice. In On Tower UK Limited v Green [2022] 4 WLR 27 the Court of Appeal upheld unrestricted upgrading rights.
Assignment: Paragraph 16
Any term that prevents or limits assignment to another operator is void. The only protection available is to require the outgoing operator to enter into an authorised guarantee agreement. In Vodafone Ltd v Potting Shed Bar and Gardens Ltd [2023] EWCA Civ 825 the Court of Appeal confirmed that an operator who acquires Code rights by assignment retains full rights to seek renewal under Paragraph 33.
Rent review
Standard practice, as confirmed in recent Tribunal decisions, is for rent to be reviewed every five years in line with RPI or CPI. The Tribunal has also accepted an open market review trigger if the operator ceases to hold Code rights or assigns to a non-Code operator. How the rent itself is valued is explained in the phone mast rent guide.
What is different for rooftop sites?
Leases for rooftop installations involve considerations that do not arise with standalone masts:
What should a standalone mast lease include?
Greenfield mast sites on farmland, rural estates or open ground present their own points:
Which court decisions shape phone mast lease terms?
Vache Farm [2024] UKUT 216 (LC)
The current leading authority on both rent and lease terms for rural mast sites: a 10-year lease, tenant break at year 5, landlord's redevelopment break from the fifth anniversary on 18 months' notice, RPI-linked reviews every five years, and the current rural rent benchmark.
On Tower UK Ltd v BT plc [2025] EWCA Civ 844
Strict compliance with every condition of a break clause is essential when founding a Paragraph 31 termination notice. BT's termination was void because the notice cited the wrong ground. Now before the Supreme Court.
On Tower UK Ltd v Green [2022] 4 WLR 27
Landowners cannot contractually prevent equipment upgrades where the Paragraph 17 conditions are satisfied.
Vodafone Ltd v Potting Shed Bar and Gardens Ltd [2023] EWCA Civ 825
Operators who acquire Code rights through assignment retain full renewal rights under the Code, which matters where the original operator has been replaced through corporate restructuring.
Cornerstone v Compton Beauchamp Estates [2022] UKSC 18
Operators with existing agreements protected under the Landlord and Tenant Act 1954 must renew under that Act, not under the Code. One of the most important protections for landowners with pre-2017 leases until the PSTI Act changes took effect on 7 April 2026. The Phone Mast Advice Company instigated and advised on this case.
What changed on 7 April 2026?
On 7 April 2026, Sections 61 to 64 of the PSTI Act 2022 came into force, inserting a new Section 34A into the Landlord and Tenant Act 1954. For the first time, qualifying telecoms tenancies that renew under the 1954 Act are subject to the Code’s no-network assumption when rent is assessed on renewal. This removed the financial advantage that landowners with pre-2017 leases previously enjoyed under Compton Beauchamp.
- →Transitional provisions ensure that rents already received are not required to be repaid
- →Interim rent is split: periods before 7 April 2026 are valued under the old rules, and periods from that date onwards under the new framework
- →Since 30 July 2026, new 1954 Act renewal proceedings for these telecoms leases are heard by the First-tier Tribunal and the Upper Tribunal instead of the courts; Code disputes have been heard by the First-tier Tribunal (Property Chamber) since 6 April 2024
- →Since November 2023, an operator must consider alternative dispute resolution, where reasonably practicable, before applying to impose Code rights, and both sides must do so before applying for new terms under Paragraph 33

Phone mast lease: frequently asked questions
How long does a phone mast lease last?
There is no statutory minimum or maximum, but the Upper Tribunal now typically imposes a 10-year term with a tenant break at year 5 and a landlord's redevelopment break exercisable from the fifth anniversary on 18 months' notice, the pattern set in the 2024 Vache Farm decision. Rent is usually reviewed every five years, linked to RPI or CPI.
What happens when my phone mast lease expires?
It does not simply end. Under Paragraph 30 of the Electronic Communications Code the agreement continues in force by statute until it is properly terminated. To end it, the site provider must serve a Paragraph 31 notice giving at least 18 months' notice on one of four statutory grounds, and if the operator serves a counter-notice within three months, the matter goes to the Tribunal.
Can I refuse a phone mast lease or make the operator leave?
Rarely. Under Paragraph 21 the Tribunal can impose an agreement if the prejudice to you can be adequately compensated in money and the public benefit outweighs it, a test operators almost always satisfy. The main exception is the redevelopment defence under Paragraph 21(5): a firm, settled and unconditional intention to redevelop, with a reasonable prospect of carrying it out.
Can the operator upgrade or share the mast without my consent?
Usually, yes. Paragraph 17 permits upgrading and sharing without consent where there is no more than a minimal adverse impact on appearance and no additional burden on you, and the PSTI Act extended similar rights to older agreements through Paragraph 17A, subject to 21 days' notice. Terms restricting assignment to another operator are void under Paragraph 16.
Should I sign the operator's proposed lease terms?
Not without advice. Draft Heads of Terms are prepared by the operator's advisers and represent an opening position. Break clause drafting is critical: in On Tower v BT (2025) a termination failed because the break notice cited the wrong ground. Protections such as fee recovery, reinstatement obligations and rent review terms are commonly improved with landlord-side input.
Is a phone mast agreement always a lease?
No. Some agreements are licences or wayleaves, which do not grant exclusive possession. The label matters less than the substance: what the operator actually has on the ground, and whether the agreement pre-dates 28 December 2017 and is protected by the Landlord and Tenant Act 1954, decide which renewal regime applies.
