A group right for leaseholders of flats to manage the building they live in without proving that their manager is at fault or paying any premium. The right must be exercised through a special company (an RTM company) set up by leaseholders for that purpose. A number of conditions must be met for this right to be exercisable, notably that two-thirds of the flats must be occupied by qualifying tenants. A qualifying tenant is any leaseholder whose lease was originally granted for a period exceeding 21 years. Where an RTM company has acquired RTM, it will be responsible for the management functions under all of the leases held by qualifying tenants in the building, such as services, repairs, maintenance, insurance, and management of the whole or part of the premises.
