Section 20 Consultation UK: How to Consult Leaseholders on Major Works (2026)

Section 20 of the Landlord and Tenant Act 1985 requires freeholders and property managers to formally consult leaseholders before carrying out qualifying works that will cost any single leaseholder more than £250, or qualifying long-term agreements worth more than £100 per leaseholder per year. Skipping the process — or doing it badly — caps your cost recovery at £250 per leaseholder, no matter how much you spent.

What triggers the obligation

The £250 threshold applies per leaseholder, not per block or total contract value. A job costing £3,000 across a building with 10 flats triggers section 20 if any one leaseholder's share exceeds £250. Freeholders often miscalculate this by dividing the total equally, then discover that one leaseholder's apportionment under their specific lease pushes them past the threshold.

Qualifying long-term agreements — typically contracts with a single contractor lasting more than 12 months — are caught by a separate £100-per-leaseholder-per-year threshold. Maintenance contracts, cleaning agreements and grounds-keeping deals all count if they run long enough.

Works carried out by a right-to-manage company or a recognised tenants' association's own contractor are also caught. The obligation follows the function, not the legal entity doing the spending.

The three-stage process under the Service Charges (Consultation Requirements) (England) Regulations 2003

The statutory procedure divides into three notices. Getting the sequence right matters — courts and the First-tier Tribunal (Property Chamber) have refused to allow cost recovery where landlords have skipped stages or served notices out of order.

Stage 1: Notice of Intention

Send a written notice to every leaseholder and any recognised tenants' association. The notice must describe the proposed works, invite observations within 30 days, and ask leaseholders whether they can nominate a contractor they would like you to invite to tender. The 30-day consultation window is fixed; you cannot shorten it.

Stage 2: Notice of Estimates (Paragraph B notice)

Obtain at least two estimates — one from any contractor nominated by the leaseholders or the tenants' association. Circulate a second notice setting out all estimates, along with a summary of the observations received at stage 1 and your responses. Leaseholders then have a further 30 days to submit observations. If you intend to accept an estimate that is not the lowest, you must state your reasons.

Stage 3: Notice of Reasons (if applicable)

Where you proceed without accepting the lowest tender, or without obtaining a nomination from leaseholders, serve a written notice explaining why. This is not a separate consultation round — it is a disclosure obligation. Courts have treated the absence of reasons as a factor when considering applications to dispense with consultation requirements.

What happens if you get it wrong

The penalty is financial, not regulatory. Under section 20B of the 1985 Act, a landlord who fails to comply with the consultation requirements cannot recover more than £250 per leaseholder from service charges, regardless of what was actually spent. On a 30-flat block with a £120,000 roof replacement, that means a potential recovery shortfall of over £112,000.

Leaseholders can apply to the First-tier Tribunal for a determination that the costs are unreasonable or that the consultation was defective. The Tribunal has wide discretion on what charges are payable. Procedural defects — even minor ones — can result in full cost disallowance, with recovery capped at £250 per leaseholder.

A related trap: the 18-month rule under section 20B(2). If you fail to serve a notice of intent to recover costs within 18 months of incurring them, the right to recover through service charges is lost entirely.

Applying to dispense with consultation

Section 20ZA allows a landlord to apply to the First-tier Tribunal for dispensation — effectively asking it to waive the normal procedure. The Tribunal grants dispensation where it is satisfied that doing so would not prejudice the leaseholders. Emergency works (a roof collapsing, a lift failing mid-winter) are the clearest cases.

Applications must be made before the works begin, or as close to the start as practical. Retrospective dispensation is theoretically available but the Tribunal scrutinises it closely. In Daejan Investments Ltd v Benson [2013] UKSC 14, the Supreme Court held that dispensation can be granted even where there has been procedural failure, provided leaseholders suffer no real prejudice — but the freeholder was required to reduce the leaseholders' aggregate liability for the works by £50,000 as a condition of dispensation. Dispensation is not a get-out-of-jail card.

Recognised tenants' associations

A recognised tenants' association (RTA) under section 29 of the 1985 Act must be included in every notice. The RTA has the right to nominate a surveyor to inspect documents and inspect proposed works. Excluding an RTA — even unintentionally — is a procedural defect the Tribunal takes seriously.

An RTA gains recognition either by certificate from the First-tier Tribunal or by written acknowledgement from the landlord. Check whether one exists before you start. If leaseholders subsequently form an RTA mid-consultation, you may need to restart stage 1.

Practical checklist before you serve notices

Keep a paper trail from the start. Courts and the Tribunal will ask for evidence that notices were served on every leaseholder and, where relevant, the RTA. Recorded delivery alone is not enough — keep an addressed envelope list and proof of posting for each flat.

Check the lease before calculating apportionment. Many leases contain fixed percentage shares that do not divide evenly, and some exclude certain works from service charge recovery altogether. A section 20 consultation cannot override what the lease actually says about recoverable costs.

Use a consistent description of works across all three stages. The Tribunal has rejected consultations where the description in the stage 1 notice differed materially from the works actually carried out — a re-specification mid-consultation may require starting again.

Common mistakes freeholders make

The most frequent error is running stage 1 and stage 2 as a single combined notice. The 1985 Act and the 2003 Regulations treat them as distinct stages with separate observation periods. Combining them has been held to render the consultation void in several tribunal decisions.

A second common failure is treating the 30-day period as a minimum rather than a fixed requirement. Serving a stage 1 notice and then issuing stage 2 notices 25 days later — because a contractor has a scheduling deadline — gives leaseholders grounds to challenge the entire process.

Third: overlooking works carried out by a subsidiary or associated company. Where a freeholder uses an in-house maintenance arm, the arrangement is still caught by section 20 unless the amounts fall below the thresholds. The 2003 Regulations do not distinguish between arms-length and related-party contracts.

What leaseholders can do if consultation fails

Leaseholders who believe consultation was defective can apply to the First-tier Tribunal under section 27A of the 1985 Act for a determination of the reasonableness of service charges. The application costs £100–£200 and does not require a solicitor. The Tribunal can reduce or disallow charges, award costs against the landlord, and recommend the manager be replaced under a management order under the Landlord and Tenant Act 1987.

Where the sums involved are large, leaseholders should also check whether the freeholder has complied with sections 21–22 of the 1985 Act on service charge accounts and inspection rights. Withholding demand for summary accounts is itself a separate breach.

Section 20 consultation is procedural law — the rules exist precisely because the money comes from leaseholders who have no direct control over how it is spent. Follow each stage, document every step, and the process protects both sides.
