What Happens If You Don't Serve Section 20

Section 20 of the Landlord and Tenant Act 1985 requires landlords to consult leaseholders before carrying out qualifying works, or entering into a qualifying long-term agreement, that will result in service charge contributions above the statutory threshold. The mechanics are in the Service Charges (Consultation Requirements) (England) Regulations 2003. If the consultation is not carried out — or not carried out correctly — the landlord's ability to recover the cost through the service charge is capped.

What the cap actually is

For qualifying works, the cap is £250 per contributing leaseholder, no matter what the works cost. If you spend £180,000 on external decorations across a block of 20 flats and you didn't consult, you can recover £250 from each leaseholder — £5,000 total. The remaining £175,000 falls on the landlord.

For a qualifying long-term agreement (QLTA), the cap is £100 per leaseholder per year. A 5-year unconsulted lifts contract at £3,000 a year per leaseholder becomes £100 a year per leaseholder in cost recovery.

The cap is not discretionary. It is not a maximum penalty that a tribunal might choose to impose. It is the statutory ceiling on what a leaseholder is liable to pay, and the tribunal's role is to apply it.

Why "honest mistake" isn't a defence

Section 20 is procedural. The tribunal is not asked whether the works were reasonable, whether the price was fair, or whether the landlord acted in good faith — those questions belong to a separate reasonableness challenge under section 19. The Section 20 question is narrower and colder: was the consultation carried out in accordance with the regulations?

Honest mistakes fail that test as reliably as bad ones. A notice served a day late is a notice served a day late. A Stage 2 statement that omitted a summary of the observations received on Stage 1 is non-compliant, even if no observations were received. A contract awarded before the 30-day observation window closed is awarded outside the consultation, even if every leaseholder would have supported it.

The one escape route: Section 20ZA dispensation

Section 20ZA of the 1985 Act allows the First-tier Tribunal to dispense with any or all of the consultation requirements. It is the only route back from a failed consultation. Two things about it matter.

First, it is discretionary. The tribunal is not obliged to grant dispensation, and you have to apply and pay a fee for the privilege of asking. Second, since the Supreme Court's decision in Daejan Investments Ltd v Benson [2013] UKSC 14, the analysis is dominated by prejudice. The tribunal asks whether the leaseholders have suffered any relevant prejudice as a result of the failure to consult, and if so whether that prejudice can be addressed by conditions — commonly a reduction in the recoverable cost or a payment of the leaseholders' legal fees.

Where the failure is minor and no prejudice is shown, dispensation is often granted. Where the failure is systemic — no consultation at all, contracts already awarded, work already done — expect the tribunal to look hard at what leaseholders lost and to impose conditions accordingly. Dispensation is a life-raft, not a plan.

Genuine emergencies

Dispensation is also the mechanism for genuine emergencies. If a roof section collapses in a storm and the works cannot wait 30 days, the landlord can apply to the tribunal under Section 20ZA for dispensation from consultation for those specific works. The application should be prompt and the emergency real; "we ran out of time" is not an emergency.

What "getting it right" actually looks like

The compliant path is not complicated, but it is unforgiving of gaps:

• A Notice of Intention that contains all the statutory content, served on every contributing leaseholder, with proof of service recorded per leaseholder.
• A 30-day observation window counted from the date of service, with any observations received filed and considered.
• A Statement of Estimates naming at least two estimates — one from a wholly unconnected party — with a summary of the Stage 1 observations and the landlord's response, again served on every contributing leaseholder with proof.
• Where required, a Notice of Reasons within 21 days of contract award, addressing the observations on the estimates.
• An audit trail that lets you produce, on demand, the notices served, the dates served, the addresses served to, and the observations received.

Whether you build that with spreadsheets, Word and Outlook, or with a tool designed for the job, the substance is the same. What you cannot do is skip it and hope. The £250 cap does not care.
