Section 146 Notice for Commercial Lease Breaches

A Section 146 notice is generally required before a commercial landlord can enforce a right of re-entry or forfeiture for a breach of lease other than non-payment of rent. The notice must identify the breach, require remedy where the breach is capable of remedy and require monetary compensation.

Section 146 notice: the short answer

What is a Section 146 notice?

A Section 146 notice is a formal notice served under section 146 of the Law of Property Act 1925 before a landlord enforces a right of re-entry or forfeiture for many breaches of a lease other than non-payment of rent.

The notice must specify the breach complained of. If the breach is capable of remedy, it must require the tenant to remedy it. It must also require the tenant to make compensation in money for the breach.

The landlord must then allow the tenant a reasonable time to comply before the right of re-entry or forfeiture is enforced.

Serving a Section 146 notice does not itself end the lease. It is a statutory step that may be required before forfeiture can later be pursued.
Statutory requirements

What must a Section 146 notice contain?

The wording must reflect the actual lease, breach and remedy sought. A generic template should not be used without checking the facts.

01

Specify the breach

The notice must identify the particular breach relied upon clearly enough for the tenant to understand the allegation.

02

Require remedy where possible

If the breach is capable of remedy, the notice must require the tenant to remedy it.

03

Require compensation

Section 146 requires the notice to require the tenant to make compensation in money for the breach.

04

Allow reasonable time

The tenant must be given a reasonable opportunity to remedy the breach where it is capable of remedy and to make reasonable compensation.

Rent arrears and other breaches

Is a Section 146 notice required for unpaid commercial rent?

Non-payment of rent

Section 146 is generally not the rent-arrears notice

Section 146 does not generally require this notice before forfeiture for non-payment of rent.

Where rent arrears have triggered a contractual right of re-entry, the landlord may instead need to consider whether the objective is possession through forfeiture or rent recovery through CRAR.

Other covenant breaches

Section 146 usually applies before forfeiture

For many breaches other than non-payment of rent, the landlord cannot enforce the right of re-entry or forfeiture until the statutory notice requirements have been satisfied.

The lease must still contain an applicable right of re-entry, and the breach relied upon must actually have occurred.

Common commercial lease breaches

When might a Section 146 notice be used?

The lease wording and evidence must be checked in every case, but common examples include the following.

Unauthorised alterations

Structural or other works carried out without consent where the lease required landlord approval.

Disrepair

Failure to comply with repairing, reinstatement or maintenance obligations, subject to additional statutory protections in qualifying cases.

Unauthorised assignment or subletting

Assignment, sharing or occupation arrangements made contrary to the lease's alienation provisions.

Prohibited use

Use outside the permitted-use covenant, or activity expressly prohibited by the lease.

Nuisance or interference

Conduct affecting neighbouring occupiers, common areas or the wider property contrary to lease covenants.

Insurance or compliance breach

Conduct affecting insurance or breaching contractual safety, access or regulatory obligations.

From breach to service

What happens before a Section 146 notice is served?

1

Check the lease

Confirm the breached covenant, the forfeiture or re-entry clause and any contractual conditions affecting enforcement.

2

Establish the breach

Gather photographs, reports, correspondence, inspection material or other evidence supporting the allegation.

3

Check whether the right has been waived

Conduct recognising the lease as continuing after knowledge of the breach can affect the landlord's right to rely on that breach for forfeiture.

4

Prepare the notice

The notice should identify the breach precisely and reflect whether remedy is possible, the compensation requirement and the relevant evidence.

5

Serve and preserve evidence

The approved service method should be used and the date, time, location, recipient or delivery method and supporting evidence retained.

6

Allow reasonable time

The landlord should assess compliance and remedy after a reasonable period before deciding whether any later forfeiture step is available.

No universal deadline

How long does a Section 146 notice have to give the tenant?

Section 146 does not prescribe one fixed number of days that applies to every commercial lease breach.

Where the breach is capable of remedy, the tenant must be allowed a reasonable time to remedy it. What is reasonable depends on the nature of the breach, the work or action required, the circumstances of the premises and the surrounding facts.

Important: a notice should not simply insert a standard deadline without considering what the breach would realistically require the tenant to do.
Legal and practical safeguards

Issues that can change the Section 146 route

Service of a notice does not cure a defective right to forfeit. These matters should be considered before the notice is relied upon.

Waiver of the right to forfeit.
Disputed breach or disputed lease wording.
Repair breaches and the Leasehold Property (Repairs) Act 1938.
Administration, liquidation or another insolvency process.
Residential or mixed-use occupation.
Whether the breach is capable of remedy.
Whether the proposed time for remedy is reasonable.
Potential relief from forfeiture.

Frequently asked questions

What is a Section 146 notice?
A Section 146 notice is a formal notice under the Law of Property Act 1925 that is generally required before a landlord enforces a right of re-entry or forfeiture for many lease breaches other than non-payment of rent.
When is a Section 146 notice required?
It is generally required where a landlord intends to enforce a right of re-entry or forfeiture for a qualifying breach of covenant other than non-payment of rent. The lease must contain an applicable right of re-entry and the breach relied upon must have occurred.
What must a Section 146 notice contain?
The notice must specify the breach, require the tenant to remedy it where the breach is capable of remedy, and require compensation in money for the breach.
Is a Section 146 notice required for commercial rent arrears?
Generally no. Section 146 does not usually require this notice before forfeiture for non-payment of rent. Rent arrears may instead raise separate questions about lease forfeiture, CRAR and waiver.
How long must a Section 146 notice give the tenant?
There is no universal number of days for every breach. The tenant must be allowed a reasonable time to remedy the breach where it is capable of remedy. What is reasonable depends on the breach and surrounding circumstances.
Does a Section 146 notice terminate the lease?
No. Serving the notice does not itself terminate the lease. It is a statutory preliminary step before forfeiture may later be considered in a qualifying case.
Can a Section 146 notice be used for disrepair?
Potentially, but repair covenant breaches can be subject to additional statutory protections under the Leasehold Property (Repairs) Act 1938. Qualifying cases require particular care and legal advice.
What happens if the tenant remedies the breach?
The effect depends on the breach, the lease and the circumstances. Where the breach is capable of remedy, Section 146 requires the tenant to be given the opportunity to remedy it before the landlord enforces the right of re-entry.
Can the tenant apply for relief from forfeiture?
Yes. A tenant and certain other interested parties may in appropriate circumstances apply to the court for relief from forfeiture. Proper service of a Section 146 notice does not prevent such an application.
Who can serve a Section 146 notice?
The notice is served on behalf of the person entitled to the reversion and the relevant right of re-entry. A professional process server or enforcement agent can carry out service, but the authority, recipients and permitted service method should be checked first.
Can UK Bailiffs prepare and serve a Section 146 notice?
UK Bailiffs can support preparation from the client's approved instructions and arrange professional service with evidence. Where the legal basis, drafting or right to forfeit is disputed or complex, solicitor approval should be obtained before service.
