Section 146 notice preparation and service
Structured notice support for commercial landlords, managing agents and solicitors dealing with a tenant's breach of covenant before forfeiture is considered. We review the supplied documents, prepare or serve the notice within the agreed scope and provide clear evidence of service.
Document-led assessment
The lease, forfeiture clause, breach evidence and authority are reviewed first.
Professional service
Planned delivery with an attendance record and appropriate evidence of service.
Integrated support
Notice service can connect with later forfeiture action where the legal conditions are met.
Notice before forfeiture
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. It is generally required before a 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 alleged breach. If the breach is capable of remedy, it must require the tenant to remedy it; it must also require monetary compensation for the breach. The landlord must then allow a reasonable time for the tenant to comply before pursuing forfeiture.
Serving the notice does not itself end the lease. It is one stage within a wider legal process, and an invalid or premature notice can undermine later action. The lease, the facts and any specialist statutory restrictions should therefore be checked before service.
Commercial lease breaches
When might a Section 146 notice be considered?
The lease must contain an enforceable right of re-entry or forfeiture, and the identified conduct must amount to a breach. Common examples include the following, but the wording and facts must be checked in every case.
Disrepair
Failure to comply with repairing, maintenance or reinstatement covenants, subject to additional statutory rules.
Unauthorised assignment or subletting
Transfer, sharing or occupation arrangements made contrary to the alienation provisions in the lease.
Prohibited use
Operating outside the permitted-use clause or using the premises for unlawful or expressly prohibited activity.
Nuisance or interference
Conduct affecting neighbouring occupiers, common areas or the wider property in breach of a lease covenant.
Insurance or compliance breach
Conduct that invalidates insurance or breaches contractual safety, access or regulatory obligations.
Evidence matters:
photographs, inspection records, correspondence, professional reports and the
relevant lease provisions should support the allegation. A Section 146 notice should not be used simply as a
pressure tactic where the breach or right to forfeit has not been established.
Law of Property Act 1925
What the notice must address
Section 146 restricts enforcement of a right of re-entry or forfeiture until the required notice has been served and the tenant has failed, within a reasonable time, to remedy the breach where it is capable of remedy and to make reasonable monetary compensation.
The wording must reflect the particular covenant and evidence. Service of a generic template without checking the lease and circumstances can create unnecessary risk.
Read the legislation at section 146 of the Law of Property Act 1925.
Specify the breach
The notice must identify the covenant and conduct relied upon with enough clarity for the tenant to understand the allegation.
Require remedy where possible
If the breach is capable of remedy, the notice must require the tenant to put it right.
Require monetary compensation
The statutory wording also requires the tenant to make compensation in money for the breach.
Allow a reasonable time
What is reasonable depends on the breach, the work or action required and the surrounding circumstances.
From documents to evidence of service
Our Section 146 notice process
Each instruction is treated as a document-led notice matter. The scope is confirmed before drafting or service work begins, and unresolved legal questions are referred back to the client or their solicitor.
Instruction received
You provide the lease, breach details, evidence, parties, property information and authority to act.
Initial review
We identify missing information and check the proposed service scope against the documents supplied.
Notice prepared or supplied
The notice is prepared from approved instructions, or your solicitor's completed notice is accepted for service.
Service planned
The service address, lease provisions, recipients, access, timing and evidence requirements are confirmed.
Notice served
An agent attends or uses the approved method, records what occurred and captures appropriate service evidence.
Report returned
You receive the service record so compliance, remedy and any later legal or forfeiture decision can be reviewed.
Legal and practical safeguards
Issues to resolve before relying on the notice
Notice service is not a substitute for determining whether the landlord has a current and enforceable right to forfeit. These issues can materially change the route.
Waiver of the right to forfeit
Demanding or accepting rent with knowledge of the breach may waive the right to forfeit that breach. Obtain advice before communicating or accepting payment.
Repairing covenant restrictions
Repair breaches can engage the Leasehold Property (Repairs) Act 1938 and require additional wording, time and court-related steps in qualifying leases.
Insolvency protection
Administration, liquidation, restructuring or other insolvency procedures may restrict enforcement or require consent from an office-holder or the court.
Relief from forfeiture
A tenant, subtenant or other interested party may seek relief. Service of a notice does not remove that right or guarantee possession.
Residential and mixed-use premises
Long residential leases and premises containing living accommodation can attract additional protections and are outside a routine commercial-only assessment.
Disputed or irremediable breach
Whether a breach occurred, whether it can be remedied and whether the proposed time is reasonable may require specialist legal advice or determination.
Frequently asked questions
Section 146 notice FAQs
Practical answers about commercial lease breaches, notice content, service, remedy and later forfeiture action.
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 a lease breach other than non-payment of rent.
When is a Section 146 notice required?
It is generally required where a landlord intends to rely on a breach of covenant other than non-payment of rent before pursuing forfeiture. The lease must contain a relevant right of re-entry, and the right must have arisen on the facts.
Is a Section 146 notice required for commercial rent arrears?
Generally, no. Section 146 does not normally require this notice before forfeiture for non-payment of rent. Rent recovery and forfeiture are different remedies, and the lease and current legal position should still be checked.
What must a Section 146 notice contain?
The notice must specify the breach, require it to be remedied if it is capable of remedy, and require the tenant to make compensation in money for the breach. Its wording should match the lease, facts and remedy sought.
How long must a Section 146 notice give the tenant?
The statute does not prescribe one universal period for every breach. The tenant must be allowed a reasonable time to remedy the breach where it is capable of remedy and to make reasonable compensation. What is reasonable is fact-specific.
Does serving a Section 146 notice end the lease?
No. The notice does not itself forfeit or terminate the lease. It is a required preliminary stage in qualifying cases before the landlord may consider court proceedings or peaceable re-entry.
Can a tenant remedy a breach after receiving the notice?
If the breach is capable of remedy, the notice must require the tenant to remedy it and a reasonable time must be allowed. Whether particular conduct is remediable can be legally complex and should not be assumed.
Can a Section 146 notice be used for disrepair?
Potentially, but repairing covenant breaches can engage additional protections under the Leasehold Property (Repairs) Act 1938. Qualifying cases may require special wording, a 28-day counter-notice opportunity and further court-related steps.
Who can serve a Section 146 notice?
The notice is served on behalf of the person entitled to the reversion and right of re-entry. A professional process server or enforcement agent can carry out service, but authority, recipients and the permitted method should be confirmed first.
Can the tenant apply for relief from forfeiture?
Yes. The tenant and some other interested parties may apply to the court for relief from forfeiture. Proper service of a Section 146 notice does not remove that right or guarantee that the landlord will recover possession.
Can UK Bailiffs prepare and serve the notice?
UK Bailiffs can support notice preparation from the client's approved instructions and arrange professional service with evidence. Where the breach, drafting or right to forfeit is disputed or complex, the notice should be approved by the client's solicitor.
What documents are needed to instruct a Section 146 notice?
Normally provide the complete lease and variations, title or ownership information, the forfeiture clause, the breached covenant, evidence of the breach, correspondence, tenant and property details, and written authority to prepare or serve the notice.
Section 146 instruction
Submit the lease and breach information for review
Use the secure form to provide the parties, property, lease, breach, evidence and intended outcome. State clearly whether UK Bailiffs is being asked to prepare and serve a notice or to serve a solicitor-approved notice.
Important:
submitting the form does not create a contract, confirm a right to forfeit or mean
that a notice has been approved or served. No action begins until the documents and scope have been reviewed
and the instruction has been expressly accepted.
