Forfeiture is one of the most powerful tools a landlord has, but it is also one of the easiest to get wrong. When a commercial or long residential tenant breaches the lease, forfeiture allows the landlord to bring the tenancy to an end and recover possession of the property.
That sounds straightforward, but the rules around how and when you can do it are strict, and a misstep can leave the landlord on the wrong end of a damages claim or, worse, having waived the right to forfeit altogether. This guide walks through what forfeiture actually involves in England and Wales, the notices and procedures a landlord needs to follow, and the practical points worth thinking about before taking action.
It is written for landlords trying to understand their position, not as a replacement for talking through your specific situation with someone experienced.
What this document is
Forfeiture is the landlord's right to bring a lease to a premature end because the tenant has broken one of the obligations set out in it. The right does not exist automatically. It only arises where the lease itself contains a forfeiture clause (sometimes called a re-entry clause or proviso for re-entry), which spells out the circumstances in which the landlord can take the property back.
Without that clause, the landlord generally cannot forfeit, even if the tenant is clearly in breach. The breaches that most commonly trigger forfeiture are non-payment of rent, failure to carry out repairs, unauthorised alterations, insolvency of the tenant, and breaches of user covenants (using the property for something the lease does not permit).
How forfeiture is carried out depends on the type of breach. Rent arrears follow one route, other breaches follow another, and long residential leases carry extra protections for the tenant. Getting the category right at the start is essential, because the procedure is not interchangeable.
How to use this document
- Confirm the lease allows forfeiture. Read the lease carefully and check for a forfeiture or re-entry clause. Identify exactly what the clause covers, because some clauses list specific breaches while others are drafted more broadly. If the lease is silent, forfeiture is almost certainly off the table and you will need to consider other remedies such as a damages claim or, for rent arrears, commercial rent arrears recovery.
- Identify the breach and avoid waiver. Pin down precisely what the tenant has done wrong and when you became aware of it. From that moment, be careful not to do anything that suggests you still treat the lease as alive, such as demanding or accepting rent, because this can waive your right to forfeit for that breach. Waiver is one of the most common traps landlords fall into, and it can be accidental.
- Serve a section 146 notice (for breaches other than rent). For any breach apart from non-payment of rent, you must serve a notice under section 146 of the Law of Property Act 1925 before forfeiting. The notice has to specify the breach, require it to be remedied if it can be, and give the tenant a reasonable period to put things right. What counts as reasonable depends on the nature of the breach.
- Observe extra protections where they apply. Where the breach relates to disrepair and the lease has a certain length remaining, the Leasehold Property (Repairs) Act 1938 may apply and the tenant can serve a counter-notice requiring the landlord to get court permission before proceeding. Long residential leases carry further protections under the Commonhold and Leasehold Reform Act 2002, which restricts forfeiture for small arrears or unproven breaches.
- Take possession by peaceable re-entry or court proceedings. Once the notice period has expired without remedy, the landlord can either re-enter the property peaceably (typically by changing the locks outside business hours, and only for commercial premises) or issue court proceedings for possession. Peaceable re-entry is quicker but carries real risks, including the tenant applying for relief from forfeiture, which the courts grant more often than many landlords expect.
Common questions
Q Can a landlord forfeit a lease without a forfeiture clause?
In most cases, no. The right to forfeit comes from the lease itself, so if there is no forfeiture or re-entry clause, the landlord cannot simply end the tenancy because of a breach. There are very limited exceptions, but they are rare in practice. If the lease does not give you this right, you will normally need to rely on other remedies such as suing for damages, pursuing rent arrears, or negotiating a surrender.
Q What is waiver and why does it matter?
Waiver happens when the landlord, knowing about a breach, does something that treats the lease as continuing. The classic example is sending a rent demand or accepting rent after finding out about the breach. Once waiver occurs, the right to forfeit for that particular breach is lost, although future or continuing breaches may still give rise to a fresh right. Because waiver can happen through routine administrative actions, landlords need to be cautious from the moment a breach comes to light.
Q Do I need a court order to forfeit a commercial lease?
Not necessarily. For commercial premises, a landlord can often forfeit by peaceable re-entry, meaning physically retaking the property by changing the locks, usually when the building is unoccupied. However, this route carries risks, and if the tenant applies for relief from forfeiture, the court can reinstate the lease. Court proceedings are slower but give a clearer outcome. Many landlords take the court route where the position is contested or the stakes are high.
Q Can a tenant get the lease reinstated after forfeiture?
Yes. Tenants can apply to the court for relief from forfeiture, and the court has wide discretion to grant it, particularly where the breach has been remedied or the tenant offers to remedy it and pay the landlord's costs. Relief is granted fairly readily for rent arrears where the tenant pays what is owed. For other breaches, it depends on the circumstances. This is why forfeiture is rarely the clean ending landlords sometimes expect.
Q Is forfeiture available for residential tenancies?
The position is more restricted for residential property. Statutory protections prevent landlords of dwellings from using peaceable re-entry while anyone is lawfully residing there, so a court order is required. For long residential leases, additional protections under the Commonhold and Leasehold Reform Act 2002 limit when forfeiture can be pursued, including restrictions on forfeiting for small arrears or breaches that have not been formally determined. Short assured shorthold tenancies follow an entirely different possession regime.
Q How long should the section 146 notice period be?
The statute says the tenant must be given a reasonable time to remedy the breach, but it does not put a number on what reasonable means. It depends heavily on the type of breach. Simple breaches might need only a short period, while substantial repair obligations could take months. Getting this wrong is a real risk: too short a period and the forfeiture may be challenged. It is worth thinking carefully about what is genuinely achievable.
Q What happens to sub-tenants when a lease is forfeited?
Sub-tenancies and other derivative interests generally fall away when the head lease is forfeited, which can be harsh on parties who have done nothing wrong. However, sub-tenants and mortgagees have their own right to apply for relief from forfeiture and can often secure a new lease directly from the landlord on the original terms. This is something landlords should factor in before forfeiting, particularly where the property has valuable occupational sub-tenants.
