Holding over describes the situation where a tenant or occupier remains in possession of premises after the contractual lease or tenancy has expired, without a new lease yet completed. It is a descriptive term used in property and landlord and tenant practice across England and Wales, Scotland, Northern Ireland and Ireland, rather than a technical statutory label.Legally, the consequences of holding over depend on the parties’ conduct, any statutory framework and the terms of the expired lease. Common outcomes include: a statutory continuation tenancy (for example under the Landlord and Tenant Act 1954 in England and Wales, or Irish landlord and tenant legislation), an implied periodic tenancy on the same or similar terms, or the occupier becoming a tenant at sufferance or trespasser liable for mesne profits or damages for use and occupation.Key issues when advising on holding over include: whether rent has been accepted; whether notices to quit, break notices or statutory notices have been served; the impact on security of tenure and renewal rights; and potential dilapidations and liability exposure. Usage and core concepts are broadly consistent across the UK and Ireland, though the detailed statutory regimes differ by jurisdiction.
