A Guide to Section 26 Notices
This is the relevant Section of the Landlord and Tenant Act 1954 which a Tenant can use to bring their current lease to an end and is commonly used to extend the current terms of the lease which will continue until the end of the Notice period.
Section 26 Notices served by Tenants can be no less than six and no more than twelve months in length.
If the Landlord has not served a Section 25 Notice bringing the arrangement to an end, then service of a Section 26 Notice will block the Landlords ability to serve a Section 25 Notice and possibly be of advantage to the Tenant, in particular in retaining the current level of rent until the end of the Notice period.
