As is the case with assured shorthold tenancies, lodger agreements will stipulate when the lodger can leave the property.
Lodgers with fixed term agreements can leave the property if their agreements contain a break clause that allows for this or by following the notice procedure (if any) set out in their agreements. Lodgers can also try to obtain the agreement of their landlords to an early termination. Without this agreement, lodgers will be liable to pay rent until the end of the fixed term.
If the lodger has a periodic agreement, they must give the landlord the notice set out in the agreement.
If the lodger has an excluded licence, the notice period must be "reasonable". The standard notice period will be at least the length of the rent period and will end on a rent day. However, the lodger and the landlord are free to agree otherwise.
