For tenancies created before January 1989, this was the usual type of private letting. Except in very limited circumstances, no new regulated tenancies could be created after January 1989. The greatest decline in such lettings was among those whose rent was not registered. Nowadays, the majority of tenants with regulated tenancies are elderly people, often living alone. Under a regulated tenancy, either the landlord or the tenant can apply to the local rent officer for registration of a fair rent.
Fair rents are generally lower than market rents for the same type of property.
The requirement to go to court where the tenant does not leave also applies to this type of tenancy. Residents of these have certain rights under the Mobile Homes Act 1983, such as security of tenure and a written agreement with the park owner. However, most conditions of the arrangement are a matter for the agreement. It is estimated that there are 200,000 permanent residents of park homes. Mostly they are retired people, living alone or as part of a couple.
