What Do the PSTI Act 2026 Changes Mean for Phone Mast Landlords?

The Product Security and Telecommunications Infrastructure Act 2022 (PSTI Act) represents the most significant change to telecommunications lease law in over a decade. From 7 April 2026, Sections 61-64 come into force, fundamentally altering how rent is calculated for lease renewals on phone masts, telecom cabinets, and related infrastructure.

For UK phone mast landlords, this isn't just another regulatory update — it's a potential £100,000+ impact on your portfolio. Understanding these changes and acting strategically could be the difference between securing fair rent and accepting significantly reduced income for the next 25 years.

This comprehensive guide explains everything you need to know about the PSTI Act 2026 changes and what they mean for your phone mast investments.

Understanding the PSTI Act: The Big Picture

What Is the PSTI Act?

The Product Security and Telecommunications Infrastructure Act 2022 was enacted to:

1. Improve UK telecommunications security
2. Mandate minimum security standards for connectable products
3. Reform how telecom operators pay for site access (this is the part affecting landlords)

The Act received Royal Assent on 6 December 2022, with most provisions taking effect in stages. The critical date for landlords is 7 April 2026 — when Sections 61-64 take effect.

Why Does It Matter for Landlords?

Prior to these changes, when a phone mast lease came up for renewal, rent was typically calculated based on:

• Market value: What the site would fetch in open competition
• Existing use value: The value of having an established telecom installation
• Comparable rents: Evidence from similar sites in the area

This system generally favoured landlords, particularly those with well-located sites and existing infrastructure.

From 7 April 2026, the calculation changes dramatically:

Rent will be based on the "no-network" assumption — as if the telecom equipment didn't exist.

In plain English: operators will only pay for the land, ignoring the value of their mast, equipment, and network infrastructure.

The Four Key Sections Explained

Section 61: The "No-Network" Assumption

This is the core provision affecting landlords. Section 61 establishes that when calculating rent for Code rights:

The value of the electronic communications network (the mast, equipment, and infrastructure) must be disregarded in calculating the consideration payable for the grant of rights.

What this means:

• If your site is worth £15,000/year under the old system, you might now receive £5,000-£8,000
• The operator's equipment adds no value in the calculation
• Only bare land value counts

Section 62: Application to Existing Leases

Section 62 clarifies when the new rules apply:

• New leases: The new rules apply to any lease granted after 7 April 2026
• Renewals: Any renewal notice served after 7 April 2026 falls under new rules
• Transitional: Leases with notices served BEFORE 7 April 2026 may still use old rules

Critical planning point: If your operator serves a Section 26 Notice before 7 April 2026, you may still negotiate under the old system. This is why timing matters.

Section 63: Tribunal Determination

Section 63 establishes the dispute resolution process:

• Either party can apply to the First-tier Tribunal (Property Chamber) if they disagree on rent
• The tribunal must apply the "no-network" assumption
• Landlords can still challenge procedural issues

Section 64: Code Consolidation

Section 64 tidies up various Code provisions but includes important clarifications on how the new provisions interact with existing law.

The Financial Impact: Real Examples

Understanding the numbers is crucial. Here's how the PSTI Act might affect you:

Example 1: Suburban Mast

Before PSTI:

• Current rent: £12,000/year
• Market value at renewal: £14,000/year
• Operator offer: £10,500/year

After PSTI (7 April 2026):

• Land-only value: £5,500/year
• Operator likely offer: £4,000-£5,000/year
• Potential reduction: £5,000-£7,000/year
• Over a 25-year lease: £125,000-£175,000 lost income

Example 2: Rural Mast

Before PSTI:

• Current rent: £5,500/year
• Market value at renewal: £6,500/year
• Operator offer: £5,000/year

After PSTI:

• Land-only value: £2,000/year
• Operator likely offer: £1,500-£2,000/year
• Potential reduction: £3,000-£4,000/year
• Over 25 years: £75,000-£100,000 lost income

Example 3: Urban/High-Value Site

Before PSTI:

• Current rent: £28,000/year
• Market value at renewal: £35,000/year
• Operator offer: £26,000/year

After PSTI:

• Land-only value: £12,000/year
• Operator likely offer: £9,000-£11,000/year
• Potential reduction: £15,000-£19,000/year
• Over 25 years: £375,000-£475,000 lost income

These figures are indicative. Actual values depend on location, site characteristics, and specific circumstances.

Strategic Responses: What Landlords Can Do

1. Act Before 7 April 2026

If your lease is coming up for renewal, serving notice before 7 April 2026 may preserve your right to negotiate under the old rules.

Action steps:

• Review all upcoming lease expiry dates in your portfolio
• Instruct a specialist surveyor to assess renewal strategy
• Serve counter-notices or initiate negotiations immediately
• Document everything — timing is evidence

2. Lock In Current Rent

If you have a current lease with favourable terms, consider:

• Extending the lease term before 7 April 2026
• Negotiating a rent review now to lock in higher rates
• Exploring break clauses that favour you

3. Prepare for Tribunal

If negotiations fail and you must go to tribunal:

• Gather evidence of current market conditions
• Obtain independent valuation under both old and new rules
• Prepare arguments on procedural fairness
• Engage specialist telecom counsel

4. Portfolio Review

Conduct a comprehensive review of your entire portfolio:

• Identify which sites have renewals coming up
• Prioritise high-value sites for immediate action
• Consider selling sites where the PSTI impact is greatest

What Operators Are Doing Now

Major operators (Vodafone, EE, O2, Three) are already adjusting their renewal strategies:

Current Operator Tactics

1. Accelerating renewals: Operators are rushing to serve Section 26 Notices before 7 April 2026 to lock in old-system rents

2. Lower initial offers: Expect aggressive opening positions — operators know the new rules favour them

3. "Take it or leave it" approach: Some operators are offering minimal negotiation, knowing the tribunal will apply the new rules

4. Site surveys: Increased activity as operators assess which sites are worth the investment under new economics

What This Means for You

The operator knows they have leverage. Without expert representation, you're at a significant disadvantage. The playing field has tilted further toward operators — professional help is more important than ever.

Frequently Asked Questions

Q: Will ALL my leases be affected?

A: Only leases that grant rights under the Electronic Communications Code. Traditional commercial leases not under the Code are unaffected.

Q: Can I challenge the "no-network" valuation?

A: You can challenge procedural issues and ensure the calculation is done correctly, but the "no-network" assumption is now law. The tribunal must apply it.

Q: What if my lease renews automatically?

A: Many Code leases include automatic renewal provisions. Check whether these trigger under the new rules or preserve old terms.

Q: Should I sell my mast sites now?

A: This depends on your individual circumstances. Some landlords are selling before the new rules take effect to lock in current values. Others are holding for longer-term income. Get specialist advice on your specific situation.

Q: What about sites with shared infrastructure?

A: Shared sites (multiple operators on one mast) are more complex. The new rules apply to each operator's rights separately.

Q: Can I still negotiate better than the formula?

A: Yes. The formula provides a floor, but you can negotiate above it, particularly for:

• Sites with strategic value
• Premium locations
• Good operator relationships
• Strong negotiation

Q: What about compensation for equipment removal?

A: Under the new rules, operators must remove equipment at lease end (subject to certain exceptions). This may provide some leverage, but it's not compensation in the traditional sense.

The Role of Professional Advice

Case Study: Protecting £85,000 in Annual Income

Situation: A landlord with three sites (two rural, one suburban) faced renewal notices from CTIL. Under the old system, market rent was approximately £22,000/year combined. Under PSTI, operator offered £11,000/year.

Our approach:

1. Served counter-notices before 7 April deadline on two sites
2. Negotiated aggressively on the third (already past the deadline)
3. Secured £18,500/year combined (vs. £11,000 offered)

Result: £187,500 additional value over 25 years compared to accepting operator offers.
