What Is a Section 20 Notice and When Does It Apply?

A Section 20 notice is part of a formal consultation process that protects leaseholders from being charged for certain major works or longer-term service contracts without being given information and a chance to comment first.

For residential leasehold property in England, the rules usually apply where a proposed cost would exceed either:

£250 for any one leaseholder’s contribution towards qualifying works; or

£100 for any one leaseholder in any accounting period under a qualifying long-term agreement lasting more than 12 months.

This guide explains what counts as a Section 20 consultation, when it is required, the notices involved, what happens if the process is missed, and how RMC and RTM directors can manage it with confidence.

This article is a general guide to the consultation rules in England. It is not legal advice. Lease wording, the planned works, the contractual structure and the facts of a dispute can all affect the position.

The legal basis

Section 20 of the Landlord and Tenant Act 1985 requires consultation before a landlord, or another party entitled to recover costs through residential service charges, incurs certain major expenditure.

The detailed process is set out in the Service Charges (Consultation Requirements) (England) Regulations 2003. The procedure is not identical in every case: it varies depending on whether the proposal concerns standalone qualifying works, a qualifying long-term agreement, or qualifying works carried out under an existing long-term agreement.

The principle is simple: before leaseholders are asked to meet significant costs through their service charge, they should have an opportunity to understand the proposal, make written observations and, in many cases, nominate a contractor.

When Section 20 applies

There are two principal triggers.

Qualifying works

Qualifying works are works to a building or other premises. They can include repair, maintenance, improvement or replacement work.

Consultation is required if the contribution of any one leaseholder towards the relevant works is expected to exceed £250. This is assessed by reference to the relevant set of works, not by simply adding every cost incurred during a service-charge year.

Common examples may include:

Roof repairs or roof replacement

External redecorations

Structural repairs

Major electrical, plumbing or fire-safety works to common parts

Replacement of communal windows or entrance doors

Major lift repairs, refurbishment or replacement

Resurfacing parking areas or private accessways

For example, if external redecorations are expected to cost £20,000 and one leaseholder’s estimated service-charge contribution is £1,000, the Section 20 consultation requirements are likely to apply.

Qualifying long-term agreements

A qualifying long-term agreement, often shortened to QLTA, is an agreement for works or services that lasts for more than 12 months.

Consultation is generally required if the contribution of any one leaseholder will exceed £100 in any accounting period under that agreement.legislation+1

Typical examples include longer-term contracts for:

Cleaning

Gardening and grounds maintenance

Concierge or security services

Lift maintenance

Managing-agent services

Some maintenance or compliance contracts

A three-year cleaning agreement, for example, may be a QLTA if it lasts more than 12 months and the cost allocated to any leaseholder exceeds £100 in a relevant accounting period.

Building insurance is an area that needs particular care. Whether consultation is required will depend on the contractual and service-charge arrangements, rather than insurance being automatically included in every Section 20 case.

The consultation process

People often describe Section 20 as a “three-stage” process. That is helpful as a broad introduction, but it can be misleading.

For many qualifying-works projects, there are two main consultation stages and, where the chosen contractor is neither the lowest estimate nor a leaseholder nominee, a subsequent notice explaining the reasons for selection may be required. QLTAs and works under QLTAs follow different prescribed procedures.

The notices should always be prepared against the relevant schedule in the 2003 Regulations.

Stage one: Notice of Intention

For a typical qualifying-works consultation, the landlord must serve a written Notice of Intention on each leaseholder and any recognised tenants’ association.

The notice must explain the proposed works in general terms, give the reasons they are considered necessary, invite written observations and state the deadline for responding. Leaseholders must be given at least 30 days to respond. legislation

The notice will usually also invite leaseholders and any recognised tenants’ association to nominate contractors from whom the landlord should try to obtain an estimate.

A nomination does not mean that a contractor must be appointed. However, where a proper nomination is made, it must be taken seriously and the landlord must make a reasonable effort to obtain an estimate from that contractor where the regulations require it. england.shelter

Stage two: Notice of Proposals

After obtaining estimates, the landlord must issue a Notice of Proposals in the form required for that type of consultation.

For qualifying works, this generally gives leaseholders information about the estimates, explains where supporting documents can be inspected and invites further written observations over another consultation period of at least 30 days.

The landlord should consider all observations received and respond to observations made within the statutory period. The consultation is meaningful, but it is not a leaseholder veto: the landlord or management company normally retains responsibility for making the final decision.

Notice of Reasons

Where the contract is awarded to a contractor whose estimate was neither the lowest nor obtained from a nominated contractor, the landlord may need to provide a notice explaining the reasons for the choice.

The notice is generally required within 21 days of entering into the contract. It is important to record the decision at the time, including relevant factors such as scope, competence, programme, warranties, references, insurance and value not just headline price. legislation

Different routes for QLTAs

A QLTA is not simply “qualifying works with a longer contract term.” The regulations contain distinct schedules for QLTAs, and certain circumstances may require public notice rather than the standard contractor-nomination route. Qualifying works delivered under a QLTA can also create an additional consultation requirement.

That is why it is worth identifying the legal structure before issuing the first notice. Starting the wrong process can create delay, additional cost and uncertainty about recoverability.

What happens if consultation is missed?

Failure to comply with Section 20 does not automatically prevent works from going ahead. It can, however, severely limit what can be recovered from leaseholders through the service charge.

For qualifying works, recovery is generally capped at £250 per leaseholder unless dispensation is granted. For a QLTA, recovery is generally capped at £100 per leaseholder in the relevant accounting period unless dispensation is granted.legislation+1

That risk can be significant. If essential roof works cost £80,000 but the required consultation was not completed, the management company or landlord may be unable to recover most of the expenditure through service charges.

This is especially important for RMCs and RTM companies. A procedural mistake can leave the company with a funding gap, create tension between neighbours and expose directors to difficult questions about how the decision was made.

Dispensation from consultation

The First-tier Tribunal (Property Chamber) can dispense with all or part of the consultation requirements under Section 20ZA of the Landlord and Tenant Act 1985.

Dispensation may be sought before works begin, particularly where urgent works are necessary, or after a consultation failure has occurred. The key question is usually whether leaseholders have suffered relevant prejudice because the statutory procedure was not followed.legislation+1

Urgency alone does not make consultation irrelevant. A water ingress emergency, dangerous structural issue or critical safety repair may make it impractical to wait through the full consultation periods, but evidence of the urgency, decision-making and communications with leaseholders remains important.

A company seeking dispensation should be ready to show why the normal process could not be followed, what information leaseholders received, how costs were tested and why leaseholders were not materially disadvantaged.

RMC and RTM responsibilities

In a self-managed block, the RMC or RTM company may be the party with the consultation duty, depending on its role, the lease and the contractual arrangements. Resident directors are not necessarily the landlord in their personal capacity, but they are responsible for ensuring that the company follows the required process.

This means directors should not treat Section 20 as a last-minute paperwork exercise. Before committing to a project or signing a longer-term contract, they should establish:

Whether the proposal is qualifying works, a QLTA or works under a QLTA

Whether any leaseholder’s contribution is likely to cross the relevant threshold

Which consultation schedule applies

When notices must be served and consultation periods expire

Whether leaseholder nominations need to be invited

How estimates, observations and the final decision will be documented

A complete record can be crucial if service charges are challenged later.

A better compliance workflow

Good Section 20 administration is as much about evidence as it is about sending notices.

Start by mapping the project before the supplier is selected. Define the scope, estimate the likely leaseholder contribution, identify whether the contract will run for more than 12 months and check the service-charge provisions in the leases.

Issue the correct notices early enough to respect the statutory timescales. Avoid treating the 30-day periods as a formality: they are minimum consultation windows, and decisions should not be finalised before they end.

Keep a single, accessible record containing the notices, proof of service, supplier invitations, estimates, leaseholder observations, responses, meeting notes, contractor-selection rationale, contract and subsequent works documentation.

Also communicate in plain English alongside the formal paperwork. A formal notice may meet the legal requirement, but a short explanation of why the work matters, how costs are being controlled and what happens next can substantially reduce avoidable disputes.

How Manage.Management helps

Section 20 consultations involve documents, deadlines, supplier information, resident communications and board decisions that need to be retained in a defensible audit trail.

Manage.Management provides a shared workspace for management companies, resident directors and homeowners to organise documents, track decisions, communicate with residents and keep operational records together rather than across individual inboxes.

Only include this section once the integration name and claim have been checked against the partner agreement, product documentation and live functionality.

Common misconceptions

“Section 20 only applies to huge construction projects”

Not necessarily. The trigger is based on the contribution attributable to any one leaseholder. Relatively modest communal works can require consultation if that threshold is exceeded.

“If nobody responds, we can skip the rest”

No. A lack of responses does not remove the obligation to follow the applicable process. The relevant consultation steps must still be completed.
