Section 27 notice: tenant's notice to terminate
A tenant of a business lease has a statutory right to a lease renewal under the Landlord and Tenant Act 1954 (LTA 1954).
If the tenant does not want the tenancy to continue, it can serve a notice on the landlord under section 27(1) of the LTA 1954. If the tenancy is already continuing under section 24 of the LTA 1954, the tenant can serve a notice to bring the tenancy to an end under section 27(2) of the LTA 1954.
There is no prescribed form of section 27 notice.
