Section 2 of the Leasehold Reform (Ground Rent) Act 2022 (c. 1) (“the 2022 Act”) provides for certain business leases to be excepted from the 2022 Act. Where use of the premises for business purposes are expressly permitted by the lease and the use of the premises as a dwelling significantly contributes to the business purposes, the lease will be excepted from the 2022 Act if the landlord and tenant (or prospective landlord and tenant) each give the other a written notice as specified in section 2.
