Every major works project in a UK leasehold building starts long before the contractor arrives — it starts with a notice. Section 20 of the Landlord and Tenant Act 1985 requires property managers to consult leaseholders before carrying out qualifying works over £250 per leaseholder, or entering a service contract over £100 per leaseholder a year. Behind every valid notice is a maintenance plan: condition surveys, cost estimates, a consultation timetable, and a paper trail that has to survive a Tribunal challenge.

Section 01
Where Section 20 Consultations Break Down
Section 20 was written to stop leaseholders being landed with unexpected, unreasonable bills for major works — and to give them a genuine say before contracts are signed. In practice, most disputes that reach the First-tier Tribunal (FTT) are not arguments about whether the roof needed fixing. They are arguments about process: a notice sent late, an observation ignored, an estimate never obtained from a nominated contractor.
01
Missed 30-Day Windows
Each of the three stages carries its own minimum 30-day observation period. Tracking three separate deadlines across dozens of open projects by spreadsheet is where compliance quietly slips.
02
Incomplete Estimate Comparison
Landlords must obtain at least two estimates, including one from any contractor nominated by leaseholders. Skipping a nominated contractor is one of the most common grounds for a successful challenge.
03
No Record of Observations
Every leaseholder comment must be considered and summarised before the next notice goes out. Without a logged record, a landlord cannot prove that consideration ever happened.
04
Cost Recovery Capped
Get the process wrong and the amount recoverable per leaseholder is capped at £250 for qualifying works, or £100 a year for a long-term agreement — regardless of the actual bill.
Section 02
The Three-Stage Notice Process
Section 20, as set out in the Service Charges (Consultation Requirements) (England) Regulations 2003, runs through three sequential notices. Each one has to land, and be answered, before the next can be served.
Stage 1
Notice of Intention
Describes the proposed works and the reasons for them, and invites leaseholders to submit written observations and nominate a contractor within 30 days.
Estimates
Obtaining Estimates
At least two estimates must be obtained, including one from any leaseholder-nominated contractor, before the second notice is prepared.
Stage 2
Statement of Estimates
Sets out the estimates received and a summary of Stage 1 observations, giving leaseholders a further 30 days to comment before a contractor is chosen.
Stage 3
Notice of Award / Reasons
Confirms which contractor was appointed. Where the choice was not the cheapest estimate or the leaseholder nomination, reasons must be given within 21 days.
Three notices, three 30-day clocks, one leaseholder register to keep straight.
OxMaint tracks every Section 20 notice against its statutory deadline, logs leaseholder observations against each stage, and keeps the estimate comparison ready for the day a challenge lands at the Tribunal.
Section 03
Follow the Process, or Cap the Recovery
Section 20 gives property managers a binary outcome. Run the consultation correctly and the full cost is recoverable through the service charge. Skip a step and the shortfall lands on the managing agent or freeholder, not the leaseholders.
Process Followed
Full Cost Recoverable
Notices served on time, estimates obtained from every nominated contractor, and observations properly considered and summarised at each stage.
Full works cost recoverable through service charges
Consultation record defends against FTT challenge
Leaseholder trust maintained through transparency
Process Skipped
Recovery Capped by Law
A missed notice, an unobtained nominated estimate, or an unanswered observation window is enough to trigger the statutory cap, regardless of intent.
Recovery capped at £250 per leaseholder for works
Capped at £100 a year for long-term agreements
Dispensation from the FTT possible only for genuine urgency
Section 04
Manual Tracking vs a Managed Consultation
The same three-stage process, run two different ways, produces very different outcomes for a busy managing agent handling multiple blocks at once.

Manual Tracking

Deadline Tracking
30-day windows tracked in a diary or spreadsheet across dozens of open blocks

Estimate Comparison

Estimates logged against the project, including nominated contractor status, ready to attach to the notice
Leaseholder Observations
Comments arrive by letter, email, and phone — easy to lose track of who raised what
Observations logged against each leaseholder and stage, with a summary ready for the next notice
Tribunal Readiness
Evidence assembled from paper files if a challenge is ever raised
Complete, timestamped consultation record exportable the same day a challenge is raised
Section 05
Running Compliant Consultations Without the Admin Load
Section 20 is a paperwork-heavy process by design — that is what protects leaseholders. The cost is the hours a property manager spends chasing deadlines and estimates by hand across every block they manage.
Notice and Deadline Tracking
Every Notice of Intention, Statement of Estimates, and Notice of Award is logged against its own 30-day or 21-day clock, with automatic alerts before a window closes.
Core Gap Solution
Estimate and Nomination Register
Contractor estimates and leaseholder nominations are logged in one place, so the two-estimate rule and the nominated-contractor requirement are visibly satisfied before a notice goes out.
Leaseholder Observation Log
Every observation is timestamped and attributed to a leaseholder, with a running summary ready to attach to the next stage's notice.
Frequently Asked Questions
What counts as qualifying works under Section 20?
Qualifying works are repairs, maintenance, or improvements to a building or its common parts — roof repairs, external redecoration, or lift replacement are typical examples. Consultation is required whenever the cost to any single leaseholder would exceed £250, even if the total project cost is much higher across a block of flats.
Can a landlord skip consultation for urgent works?
Yes, but only with permission. Under Section 20ZA, a landlord can apply to the First-tier Tribunal for dispensation from all or part of the consultation requirements. The Tribunal will only grant this where it is satisfied the situation is genuinely urgent and reasonable steps were still taken to inform leaseholders.
What happens if a landlord doesn't follow the Section 20 process correctly?
The amount recoverable from each leaseholder is capped by law — £250 for qualifying works, or £100 a year for a qualifying long-term agreement — regardless of the actual cost of the works. The landlord cannot recover the shortfall unless the Tribunal grants dispensation after the fact.
Does a qualifying long-term agreement need a separate consultation for works carried out under it?
Yes, in most cases. Consulting on the long-term agreement itself does not exempt individual works carried out under that agreement if those works would separately cost a leaseholder more than £250. A further consultation is generally required for that specific piece of work.
