What Commercial Lease Breaches Commonly Lead To Forfeiture Notices?
Commercial forfeiture issues most often arise from unpaid sums, unauthorised use, unlawful occupation changes, disrepair, alterations, insurance failures and breaches of statutory compliance duties. Rent arrears are usually treated differently from non-rent breaches: many commercial leases allow forfeiture for unpaid rent without first serving a section 146 notice, while most other breaches generally require a valid notice under section 146 of the Law of Property Act 1925.
Which Breaches Are Usually Remediable By A Commercial Tenant?
Most non-rent breaches are fact-sensitive but potentially remediable, including disrepair, unauthorised alterations, failure to insure, failure to provide certificates, nuisance, signage breaches, waste accumulation and planning control breaches. Remedies commonly include paying arrears, reinstating works, stopping unauthorised use, removing occupiers, carrying out repairs, providing documents or reimbursing the landlord’s costs.
What Evidence Should A Landlord Gather Before Serving A Notice?
- Payment breaches: rent ledgers, invoices, demands, bank statements and correspondence about arrears.
- Physical breaches: inspection notes, photographs, surveyor reports, schedules of dilapidations and contractor quotes.
- Occupation or use breaches: Land Registry/company checks, adverts, licences, sublease documents, witness notes and site photographs.
- Compliance breaches: enforcement notices, safety certificates, inspection reports, risk assessments and correspondence with regulators.
Why Does The Breach Type Matter For A Notice Of Forfeiture?
The breach type affects the wording of the notice, whether the tenant must be given time to remedy, and what compensation or remedial steps may be demanded. Misidentifying the covenant or asking for an unrealistic remedy can increase the risk of dispute, waiver arguments or an application for relief from forfeiture.
