Generally, a landlord cannot lawfully end your tenancy solely to avoid the Rent Pressure Zone (RPZ) rent-increase rules or reset the rent. A tenancy may be ended only on a permitted ground, such as intending to sell, move into the property, carry out substantial refurbishment or change its use, and the required notice procedure must be followed. The applicable rent-setting rules can depend on the tenancy and when it began. If you suspect a termination is retaliatory or based on a false ground, contact the RTB, and consider getting advice from a qualified housing solicitor.
