Section 20 Consultation: UK Landlord Guide 2026
Last updated: 15 September 2026
A Section 20 consultation is the statutory process under the Landlord and Tenant Act 1985 that landlords and managing agents in England and Wales must follow before charging leaseholders for major works or long-term service contracts. It currently applies once costs exceed £250 per leaseholder for works or £100 per leaseholder per year for agreements, though the government has proposed raising these thresholds to £600 and £300 respectively as of 2026.
Key Takeaways
- Priority First notes that Section 20 consultation is required under the Landlord and Tenant Act 1985 and the Service Charges (Consultation Requirements) (England) Regulations 2003 before a landlord recovers major works or long-term contract costs above set thresholds.
- Priority First highlights that the current threshold is £250 per leaseholder for qualifying works and £100 per leaseholder per year for qualifying long-term agreements, unchanged for over two decades according to the RICS Property Journal (2026).
- Priority First reports that government reform proposals, subject to a consultation that closed on 26 September 2026, would raise these thresholds to £600 and £300 per leaseholder, according to Lexology (2026).
- Failure to consult properly caps recoverable costs at £250 per leaseholder for works or £100 per leaseholder per year for agreements, per the Leasehold Knowledge Partnership (2019).
- The First-tier Tribunal can dispense with all or part of the consultation requirement under Section 20ZA where it is reasonable to do so, a route landlords increasingly rely on when timescales are tight.
What is a Section 20 consultation?
A Section 20 consultation is the formal notice-and-response procedure landlords in England and Wales must follow under Section 20 of the Landlord and Tenant Act 1985 before recovering the cost of qualifying major works or qualifying long-term agreements from leaseholders through the service charge. The detailed mechanics sit in the Service Charges (Consultation Requirements) (England) Regulations 2003, a statutory instrument that sets out notice content, timings and leaseholder rights at each stage.
The obligation applies to any landlord, freeholder, resident management company (RMC) or right-to-manage company (RTM) collecting service charges from long leaseholders. Leaseholders paying a variable service charge — one calculated against actual costs rather than a fixed sum — are the group the legislation protects.
Priority First works alongside managing agents across prime central London blocks, including in Chelsea and Knightsbridge, where 28 of its 37 documented client contracts sit as of August 2026. Understanding where Section 20 obligations begin is inseparable from the wider building management remit these blocks require, spanning maintenance planning through to compliance record-keeping.
When is a landlord legally required to carry out a Section 20 consultation?
A landlord must carry out a Section 20 consultation whenever the cost of qualifying works exceeds £250 per leaseholder, or when a qualifying long-term agreement — a contract running for more than 12 months, such as a lift maintenance or managing agent contract — will cost any leaseholder more than £100 in a service charge year.
These figures are per leaseholder, not per building, so a block with many flats reaches the threshold faster than one with few. A 2012 High Court case, Phillips and others v Francis, cast doubt on whether a "per set of works" threshold existed at all, before the Court of Appeal overturned that ruling in October 2014 and reinstated what practitioners call the "sets approach", according to the Leasehold Knowledge Partnership (2019).
Emergency works carried out to prevent immediate danger — a burst pipe or failed fire door, for example — do not remove the consultation obligation outright, but a landlord facing genuine urgency can apply to the tribunal for dispensation rather than delay essential safety measures.
What are the specific stages and timings a landlord must follow?
The Section 20 consultation process runs through two or three formal stages, each carrying its own minimum notice period and leaseholder response window. Stage one is the Notice of Intention, stage two is the Notice of Estimates, and stage three — the Notice of Reasons — only applies where leaseholders' preferred contractor was not chosen.
For stages one and two, leaseholders must be given at least 30 days to reply, meaning the full Section 20 consultation will still take at least two to three months from start to finish, according to The Property Institute (TPI) Advice Note (2026). That timescale assumes no delays in gathering estimates or responding to leaseholder observations.
| Stage | Notice | Minimum period | Purpose |
|---|---|---|---|
| 1 | Notice of Intention | 30 days | Describes proposed works; invites nomination of contractors |
| 2 | Notice of Estimates | 30 days | Shares at least two estimates; invites observations |
| 3 | Notice of Reasons | No fixed minimum, but must be given "within 21 days" of contract award | Explains choice where a nominated contractor was not selected |
Government reform proposals under consideration could shorten the 30-day windows to 21 days and introduce standardised notice forms, alongside a new 12-month deadline to start works once consultation concludes, per Lexology (2026).
What cost threshold triggers the requirement for a Section 20 consultation?
The trigger for a Section 20 consultation is currently £250 per leaseholder for qualifying works and £100 per leaseholder per year for qualifying long-term agreements, figures set by the 2003 regulations and never revised since. The RICS Property Journal (2026) confirms these qualification thresholds have not been reviewed for over 20 years, a gap widely cited as a driver behind current reform.
The government published a consultation paper titled "Strengthening leaseholder protections over charges and services" on 4 July 2026, according to GOV.UK (2026). That consultation closed on 26 September 2026 and proposed raising the works threshold to £600 per leaseholder and the long-term agreement threshold to £300 per leaseholder, per Lexology (2026).
| Threshold type | Current (2026) | Proposed | Source |
|---|---|---|---|
| Qualifying works, per leaseholder | £250 | £600 | Lexology (2026) |
| Qualifying long-term agreement, per leaseholder/year | £100 | £300 | Lexology (2026) |
Landlords and agents should budget on the current £250/£100 figures until secondary legislation confirms any change, since the Leasehold and Freehold Reform Act 2026 requires further statutory instruments before the new thresholds take legal effect.
Who is responsible for issuing the Section 20 notices?
The landlord — which may be a freeholder, a resident management company, or a right-to-manage company — bears the legal responsibility for issuing Section 20 notices, even where a managing agent handles the paperwork day to day. Delegating administration to an agent does not transfer statutory liability away from the landlord under the Landlord and Tenant Act 1985.
Managing agents typically draft and serve the Notice of Intention and Notice of Estimates on the landlord's instruction, following guidance such as the RICS Service Charge Residential Management Code. Where an RMC or RTM company is the landlord, its directors carry personal exposure to leaseholder challenge if consultation is defective, which is why competent block management matters as much as the works themselves.
"Blocks tend to buy security and building management as separate contracts, and the gaps between the two are exactly where problems live. The concierge who notices a leak, the patrol officer who spots a failed door closer — when one team owns the whole building, nothing falls between contracts." — Mo Hassan, Managing Director, Priority First
That same principle of unified accountability applies to compliance processes like Section 20: fragmented ownership between landlord, agent and contractor is where notices go missing or deadlines slip.
Can leaseholders apply to a tribunal to dispense with consultation requirements?
Leaseholders do not apply for dispensation — landlords do, under Section 20ZA of the Landlord and Tenant Act 1985, asking the First-tier Tribunal (Property Chamber) to waive all or part of the consultation requirement. The tribunal grants dispensation where it considers this reasonable, typically weighing genuine urgency, such as a collapsed roof or failed fire safety system, against any prejudice leaseholders would suffer from a shortened process.
Landlords can apply for dispensation either in advance of urgent works or retrospectively after a consultation failure comes to light. The tribunal will usually still require evidence that leaseholders were kept informed and that costs were reasonable, even where formal notice periods were bypassed.
Leaseholders opposing an application can raise financial prejudice — the argument that a properly run consultation would have secured a materially cheaper price or a better contractor. Where the tribunal finds no real prejudice, dispensation is commonly granted subject to conditions, such as a reduced recoverable cost or a requirement to obtain a second estimate retrospectively.
What happens if a landlord fails to properly consult under Section 20?
A landlord who fails to consult properly cannot recover the full cost of works or a long-term agreement from leaseholders through the service charge. The statutory minimum recoverable in that scenario is capped at £250 per leaseholder for building works or £100 per leaseholder per year for a long-term contract, according to the Leasehold Knowledge Partnership (2019).
That cap can leave a landlord or RMC absorbing tens of thousands of pounds in shortfall on a substantial roofing or lift replacement project. It is a powerful incentive for accurate record-keeping — proof that notices were served, dates were met and estimates were genuinely obtained — since defective consultation is challenged before the First-tier Tribunal under Section 27A of the same Act, which determines the reasonableness and payability of service charges.
Priority First's approach to evidence discipline in physical security carries a direct lesson here: on one 152-checkpoint mixed-use development in West London, every patrol now requires a photograph, GPS location and timestamp before it counts as complete, replacing an "all in order" occurrence book that could not prove what had actually happened. The same principle — a documented record standing in place of an assertion — is exactly what protects a landlord facing a Section 20 dispute, where the tribunal will ask for dated evidence of every notice served.
Your Section 20 consultation checklist
- Confirm whether proposed costs exceed £250 per leaseholder (works) or £100 per leaseholder per year (long-term agreements).
- Serve the Notice of Intention with at least 30 days for leaseholder observations and contractor nominations.
- Obtain a minimum of two estimates, including one from any contractor leaseholders have nominated.
- Serve the Notice of Estimates with a further 30-day response window.
- Issue a Notice of Reasons within 21 days if a nominated or lower-cost contractor was not chosen.
- Apply to the First-tier Tribunal under Section 20ZA for dispensation where genuine urgency prevents full consultation.
- Retain dated proof of service for every notice, in case of a future Section 27A service charge challenge.
- Review budgets against the current £250/£100 thresholds until the Leasehold and Freehold Reform Act 2026 reforms take statutory effect.
FAQ
What is a Section 20 consultation?
A Section 20 consultation is the statutory notice process under the Landlord and Tenant Act 1985 requiring landlords to consult leaseholders before charging them for major works over £250 per leaseholder or long-term agreements over £100 per leaseholder per year.
How long does a Section 20 consultation take?
A Section 20 consultation takes a minimum of two to three months, since stages one and two each require at least 30 days for leaseholder responses, according to The Property Institute (TPI) (2026).
What is the difference between a Section 20 consultation and a Section 20B notice?
A Section 20 consultation governs the process before major works or long-term contracts are charged, while a Section 20B notice is a separate rule requiring landlords to demand service charge costs from leaseholders within 18 months of those costs being incurred, or lose the right to recover them at all.
Can a landlord skip Section 20 consultation for emergency repairs?
A landlord cannot automatically skip Section 20 consultation for emergency repairs but can apply to the First-tier Tribunal under Section 20ZA for dispensation, which the tribunal grants where it is reasonable given the urgency and any prejudice to leaseholders.
What happens if a Section 20 consultation is not carried out correctly?
If a Section 20 consultation is not carried out correctly, the landlord's recoverable costs are capped at £250 per leaseholder for works or £100 per leaseholder per year for agreements, per the Leasehold Knowledge Partnership (2019).
Are Section 20 thresholds changing in 2026?
Section 20 thresholds have been proposed to rise from £250 to £600 per leaseholder for works and from £100 to £300 for long-term agreements, following a government consultation that closed on 26 September 2026, but the current figures still apply until secondary legislation under the Leasehold and Freehold Reform Act 2026 is enacted.
Who must issue Section 20 notices — the landlord or the managing agent?
The landlord holds legal responsibility for issuing Section 20 notices even where a managing agent prepares and serves them on the landlord's behalf, meaning liability for a defective consultation ultimately rests with the freeholder, RMC or RTM company.
Managing compliance and buildings together with Priority First
Section 20 consultation failures rarely happen in isolation — they tend to surface alongside wider gaps in how a block's compliance, maintenance and access records are kept. Priority First brings building management and security under one accountable team, so the documentation trail that protects a landlord in a service charge dispute is the same discipline applied to patrols, deliveries and contractor access across a site.
Priority First's operational data shows the value of that approach: across a 16-building prime estate, Priority First now records 250 to 280 photo-backed patrols per building, evidence that was previously unprovable under a paper-based system. That same standard of dated, verifiable record-keeping is what a landlord needs when demonstrating to the First-tier Tribunal that notices were served and estimates obtained on time.
If your block's building management, compliance record-keeping or security cover could do with a single accountable partner, get in touch with Priority First for a consultation on facilities management tailored to your building.
