Section 20 Consultation: Complete Guide for UK Managing Agents

What is Section 20 Consultation?

Section 20 of the Landlord and Tenant Act 1985 requires landlords and managing agents to consult leaseholders before carrying out qualifying works or entering into qualifying long-term agreements. Fail to follow the correct procedure and your ability to recover costs from leaseholders is capped at £250 per leaseholder — regardless of what the work actually costs.

For a 20-unit block spending £100,000 on a roof replacement, that means you could only recover £5,000 from leaseholders if you skipped Section 20 consultation. The remaining £95,000 would be unrecoverable.

Understanding Section 20 is not optional for managing agents — it's one of the most important legal obligations in residential leasehold management.

When Does Section 20 Apply?

Section 20 consultation is required in two situations:

1. Qualifying works — any works to a building where any one leaseholder would be asked to contribute more than £250.

2. Qualifying long-term agreements — any agreement with a contractor or supplier lasting more than 12 months where any one leaseholder would contribute more than £100 per year.

The £250 threshold is per leaseholder, not per project. So for a 10-unit block, works costing more than £2,500 in total would typically trigger Section 20.

The Three-Stage Consultation Process

Section 20 consultation for qualifying works involves three formal stages:

### Stage 1 — Notice of Intention

The landlord or managing agent must serve a written Notice of Intention on:

• Every leaseholder who would contribute to the cost
• Any recognised tenants' association (RTA)

The notice must:

• Describe the proposed works (in general terms)
• State why the works are needed
• Invite leaseholders to make observations within 30 days
• Invite leaseholders to nominate a contractor to be invited to tender

Key point: You must genuinely consider any observations received and any contractors nominated by leaseholders.

### Stage 2 — Notice of Estimates (Paragraph (b) Notice)

After the observation period, you must obtain at least two estimates for the works. If any leaseholder or the RTA nominated a contractor in Stage 1, that contractor must be invited to tender.

You must then serve a Notice of Estimates on all leaseholders, including:

• A copy of at least two estimates
• An invitation to make observations within 30 days
• A summary of observations received in Stage 1

If you intend to award the contract to a contractor who was not nominated by leaseholders or an RTA, you must include your reasons in the notice.

### Stage 3 — Award of Contract (if applicable)

If the contract is awarded to a contractor not nominated by leaseholders or the RTA, you must within 21 days of awarding the contract notify each leaseholder and the RTA of:

• The contractor selected
• The reason for selecting that contractor if not the lowest estimate

Common Section 20 Mistakes

Starting works before completing consultation

Works must not begin until the consultation process is complete. Emergency works are the only exception — and even then, you should apply for dispensation retrospectively.

Inadequate description of works

The Notice of Intention must describe the works clearly enough for leaseholders to understand what is proposed and make meaningful observations.

Missing leaseholders

Every qualifying leaseholder must receive the notices. If a leaseholder has sublet their property, you must serve the notice on the leaseholder (the person named in the lease), not the tenant.

Not considering nominations

If leaseholders nominate a contractor, you must invite that contractor to tender. You don't have to appoint them, but you must give them the opportunity to quote.

Incorrect timescales

Both the 30-day observation periods must be genuine — you cannot serve the Stage 2 notice before the Stage 1 observation period has expired.

Emergency Works and Dispensation

If works are genuinely urgent — for example, emergency roof repairs following storm damage — you can proceed without completing the full consultation process. However, you should:

1. Carry out the emergency works to make the building safe
2. Apply to the First-tier Tribunal (Property Chamber) for dispensation as soon as practicable
3. Keep records of why the works were urgent

The Tribunal has discretion to grant dispensation if leaseholders would not be prejudiced by the failure to consult.

Qualifying Long-Term Agreements

The Section 20 process for qualifying long-term agreements (contracts over 12 months exceeding £100 per leaseholder per year) follows a similar two-stage process:

1. Notice of Intention — describing the proposed agreement and inviting observations
2. Notice of Proposals — sharing details of at least two proposals with leaseholders

Common qualifying long-term agreements include:

• Cleaning contracts
• Lift maintenance agreements
• Caretaking or concierge contracts
• Insurance policies (in some circumstances)

Tracking Section 20 Consultations

Managing the Section 20 process manually — tracking notice dates, observation periods, nominations, and estimates — is error-prone. A missed deadline or forgotten notice can cost the block tens of thousands of pounds.

PropLinker's block management platform helps managing agents track Section 20 consultations alongside the rest of their property management workflow, ensuring no step is missed.

Conclusion

Section 20 consultation is one of the most consequential legal obligations in UK leasehold management. The financial penalty for non-compliance — being limited to £250 per leaseholder regardless of actual cost — can be catastrophic for larger projects.

The key principles are simple: consult before you commit, serve notices on every qualifying leaseholder, allow genuine observation periods, and consider all nominations and observations received.

If you're managing a leasehold block, PropLinker can help you stay on top of Section 20 obligations alongside service charge collection, GoCardless payments, and financial reporting.
