Section 20 Consultation Requirements: How to Challenge Non-Compliance at Tribunal

Last updated: March 2026

Quick Answer

Section 20 of the Landlord and Tenant Act 1985 requires landlords to consult leaseholders before carrying out qualifying works costing more than £250 per leaseholder or entering into qualifying long-term agreements costing more than £100 per leaseholder per year. If the landlord fails to consult, the maximum amount recoverable through the service charge is capped at £250 per leaseholder (for works) unless the tribunal grants dispensation. Leaseholders can challenge non-compliance at the First-tier Tribunal (Property Chamber), and your bundle should include the lease, service charge demands, evidence of the consultation failure, any dispensation application from the landlord, and correspondence documenting the breach.

Why Section 20 Consultation Matters

The section 20 consultation procedure exists to protect leaseholders from being presented with large service charge bills for works or contracts they knew nothing about and had no opportunity to influence. It is one of the most important safeguards in leasehold law, and landlords who bypass it face real financial consequences.

In practice, consultation failures are surprisingly common. Some landlords genuinely do not understand the requirements. Others cut corners under time pressure, particularly when dealing with urgent repairs. A smaller number deliberately avoid consultation because they prefer to award contracts without leaseholder scrutiny.

Whatever the reason, a failure to consult properly is not merely a procedural technicality. It directly affects the amount the landlord can recover. Understanding how the consultation process works — and knowing how to challenge non-compliance — puts leaseholders in a significantly stronger position.

The Legal Framework

Section 20 of the Landlord and Tenant Act 1985

Section 20 (as substituted by section 151 of the Commonhold and Leasehold Reform Act 2002) provides that landlords must consult leaseholders before:

• Carrying out qualifying works where the contribution of any leaseholder exceeds £250
• Entering into a qualifying long-term agreement (a contract for a term of more than 12 months) where the contribution of any leaseholder in any accounting period exceeds £100

If the landlord fails to consult, or fails to follow the prescribed consultation stages, the amount recoverable from each leaseholder is capped at £250 (for qualifying works) or £100 (for qualifying long-term agreements) — unless the First-tier Tribunal grants dispensation under section 20ZA.

The Service Charges (Consultation Requirements) (England) Regulations 2003

The detailed consultation procedure is set out in the 2003 Regulations. The procedure differs depending on whether the landlord is carrying out qualifying works or entering into a qualifying long-term agreement, and whether the landlord intends to enter into a public notice contract.

The Consultation Stages: Qualifying Works

For standard qualifying works (the most common scenario), the consultation procedure has three stages:

Stage 1: Notice of Intention

The landlord must serve a written notice on each leaseholder (and any recognised tenants' association):

Stage 2: Estimates and Notification

After obtaining at least two estimates (including one from a contractor nominated by a leaseholder, if any was nominated), the landlord must serve a further notice:

Stage 3: Notification of Award

If the landlord does not select the lowest estimate or the nominated contractor's estimate, they must within 21 days of entering into the contract give written notice to each leaseholder:

• Stating the reasons for awarding the contract to the selected contractor
• Providing a summary of any observations received and the landlord's response to them

Common Stage Failures

Each stage has specific timing and content requirements. The most frequent failures include:

• Skipping Stage 1 entirely — proceeding straight to commissioning works without any notice to leaseholders
• Insufficient description of works — a vague notice that does not allow leaseholders to understand what is proposed
• Inadequate observation period — giving leaseholders fewer than 30 days to respond
• Ignoring nominated contractors — failing to obtain an estimate from a contractor nominated by a leaseholder
• No Stage 3 notice — awarding the contract to a more expensive contractor without explanation

Qualifying Long-Term Agreements

The consultation process for qualifying long-term agreements (contracts exceeding 12 months, such as management agreements, cleaning contracts, or lift maintenance contracts) follows a similar but distinct procedure. The key differences are:

• The threshold is £100 per leaseholder per accounting year (not £250)
• The stages focus on the terms of the proposed agreement rather than specific works
• The landlord must describe the proposed agreement and invite observations before entering into it

Long-term agreement consultation failures are arguably more significant than works consultation failures, because a single agreement can affect service charges for many years. A five-year management contract awarded without consultation locks leaseholders into costs they had no opportunity to challenge.

Challenging Non-Compliance at the Tribunal

Your Options as a Leaseholder

If the landlord has failed to comply with section 20, leaseholders have two main routes:

1. Challenge the service charge under section 27A. You can apply to the tribunal for a determination that the service charges relating to the unconsulted works or agreement are limited to £250 per leaseholder (for works) or £100 per leaseholder per year (for agreements). This effectively enforces the statutory cap.

2. Oppose a dispensation application. If the landlord realises (or is advised) that consultation was defective, they may apply to the tribunal under section 20ZA for dispensation from the consultation requirements. You have the right to oppose that application and to argue that dispensation should be refused or granted only on conditions.

The Dispensation Application: Section 20ZA

Section 20ZA gives the tribunal discretion to dispense with the consultation requirements "if satisfied that it is reasonable to dispense with them." Following the Supreme Court's decision in Daejan Investments Ltd v Benson [2013] UKSC 14, the key question is whether the leaseholders would be prejudiced by the dispensation.

In Daejan, the Supreme Court held that:

• The primary question is whether leaseholders have suffered real prejudice in terms of the service charge they are required to pay
• A failure to consult does not automatically mean dispensation should be refused
• The tribunal should focus on the practical consequences of the consultation failure, not the failure itself
• Dispensation can be granted on conditions — for example, requiring the landlord to pay the leaseholders' costs of the dispensation proceedings

This means that even where consultation was entirely absent, the landlord may obtain dispensation if they can show that the works were reasonably priced and that leaseholders suffered no financial prejudice. The burden of proving that dispensation is reasonable falls on the landlord.

Preparing Your Tribunal Bundle

Whether you are challenging service charges on the basis of consultation failure or opposing a dispensation application, your bundle needs to demonstrate clearly what happened — and what did not happen.

Essential Documents

Building Your Case Against Dispensation

If you are opposing a landlord's dispensation application, your bundle should focus on demonstrating prejudice — the practical harm caused by the consultation failure:

Financial prejudice. Can you show that the works could have been carried out more cheaply? Were alternative contractors available who would have quoted lower prices? Did the absence of consultation mean you had no opportunity to propose a cheaper alternative?

Loss of opportunity to influence. Even if the works were reasonably priced, did the consultation failure deprive you of the opportunity to comment on the scope, timing, or specification of the works? Could you have proposed alternative approaches that would have been equally effective but less expensive?

Pattern of non-compliance. If the landlord has a history of failing to consult, this is relevant to the tribunal's exercise of discretion. A one-off failure is treated differently from a pattern of deliberate avoidance.

Lack of transparency. Where the landlord cannot produce documentation showing that the works were competitively tendered or reasonably priced, the absence of evidence is itself evidence of prejudice — because the leaseholders cannot verify the reasonableness of the charges.

Practical Examples: When Consultation Fails

Example 1: Emergency Works

A water pipe bursts in the communal boiler room, causing flooding. The landlord commissions emergency repairs costing £8,000 (£400 per leaseholder in a block of 20 flats). No consultation takes place because the landlord argues the works were urgent.

The law: Urgency is not a statutory exemption from consultation. The landlord should have consulted — or, if genuine urgency made that impossible, applied for dispensation promptly.

Your position: Challenge the charges under section 27A. If the landlord applies for dispensation, argue that whilst the initial emergency repair may have been unavoidable, the subsequent permanent remedial works should have been subject to full consultation. The tribunal may grant dispensation for the emergency element but require consultation for the main works.

Example 2: Repainting the Exterior

The landlord commissions exterior redecoration of the building at a cost of £60,000 (£3,000 per leaseholder). A Stage 1 notice is served, but Stage 2 is skipped — the landlord awards the contract without sending leaseholders a summary of estimates or inviting further observations.

The law: The consultation is defective. Stage 2 was omitted, depriving leaseholders of the opportunity to review competing estimates and nominate contractors.

Your position: Apply under section 27A. The recoverable amount is capped at £250 per leaseholder unless the tribunal grants dispensation. In the dispensation proceedings, argue that the leaseholders were prejudiced because they had no opportunity to review estimates, propose alternatives, or comment on the selected contractor's price. Include comparable quotes to show the works could have been done more cheaply.

Example 3: Long-Term Management Agreement

The landlord enters into a five-year management agreement with a managing agent at £15,000 per year for a block of 30 flats (£500 per leaseholder per year). No consultation takes place.

The law: This is a qualifying long-term agreement. The recoverable amount is capped at £100 per leaseholder per year without dispensation — a significant reduction from the £500 actually charged.

Your position: The financial impact of non-consultation is dramatic here. Without dispensation, the landlord can recover only £100 per leaseholder per year instead of £500. This creates strong leverage to negotiate better terms or a change of managing agent.

The Impact on Service Charges

Understanding the financial consequences of consultation failure is essential:

The cap applies per leaseholder. In a block of 50 flats where qualifying works cost £250,000, the cap reduces the recoverable amount from £5,000 per leaseholder to £250 per leaseholder — a saving of £4,750 each. The financial incentive to challenge non-compliance is often substantial.

Frequently Asked Questions

Does the landlord need to consult on every repair?

No. The consultation requirement only applies to qualifying works where the cost to any individual leaseholder exceeds £250, and qualifying long-term agreements where the cost to any leaseholder exceeds £100 per year. Routine maintenance and minor repairs below these thresholds do not require consultation.

Can the landlord avoid consultation by splitting works into smaller jobs?

Artificially splitting works to avoid the consultation threshold is not permitted. The tribunal will look at whether the works are properly regarded as a single project. Repainting the entire exterior of a building over three consecutive weekends is one set of qualifying works, not three separate jobs below the threshold.

What if the landlord says the works were an emergency?

There is no emergency exemption from section 20 consultation. However, the landlord can apply for dispensation under section 20ZA, and genuine urgency is a factor the tribunal will consider. The tribunal may grant dispensation for truly emergency works (such as making safe a collapsed wall) but is unlikely to do so for works that could reasonably have been planned and consulted upon.

Can dispensation be granted after the works are completed?

Yes. There is no time limit for applying for dispensation, and many applications are made after the works have been carried out. The timing of the application does not prevent dispensation from being granted, though the tribunal will consider whether the leaseholders were prejudiced by the post-hoc nature of the application.

What conditions can the tribunal attach to dispensation?

Following Daejan, the tribunal can impose conditions on dispensation. Common conditions include requiring the landlord to pay the leaseholders' reasonable costs of the dispensation proceedings, or limiting the amount recoverable to a figure lower than the full cost. The conditions should be tailored to address the prejudice caused by the consultation failure.

Can I challenge consultation failure years after the works were done?

Yes. There is no specific time limit for challenging service charges on the basis of consultation failure, though the Limitation Act 1980 may apply to restrict recovery of overpaid amounts to six years. The sooner you act, the better — evidence is fresher and documents are more readily available.

Should I make a section 20C application alongside my challenge?

Yes. A section 20C application prevents the landlord from adding its legal costs of the tribunal proceedings to the service charge. This is important because without it, the landlord could effectively pass the cost of defending the proceedings back to the very leaseholders who brought the challenge.
