It is important to decide whether you will take in a lodger or a sub-tenant. Sub-tenants have more rights than lodgers, and may be harder to evict if you want them to leave.
Lodgers
A lodger does not have exclusive rights to any part of the property. This means that you as will keep the right to go into any rooms used by the lodger.
If you have an introductory tenancy, you will need to contact your local Housing Office to request permission to take in a lodger.
Secure tenants can take in lodgers without requesting permission as long at this doesn’t cause overcrowding at the property.
Sub-tenants
A sub-tenant has exclusive rights to part of the property. This means that you would not be able to go into their room without permission. They may have a lock on the door to their room.
You must contact your local Housing Office to request permission to take in a sub-tenant.
