What is Void Period?
A period when a rental property is empty and earning no rent, during which the landlord continues to bear costs such as Council Tax, utilities and mortgage interest.
Full Definition
A void period is the interval between one tenancy ending and a new tenant moving in. Even well-managed properties experience voids: tenant turnover, property refurbishment between lets, difficulty finding suitable tenants, and wider market conditions can all cause gaps in income. The national average void period for UK buy-to-let properties is typically estimated at two to four weeks per year in normal market conditions, but this can extend considerably during economic downturns, in oversupplied rental markets, or for properties with specific characteristics that limit the tenant pool. During a void, the landlord remains responsible for all fixed costs: Council Tax (the landlord pays Council Tax on empty properties, though some councils offer a discount for the first month), utilities (if included in the tenancy or standing charges for disconnected properties), mortgage interest payments, and buildings insurance. Experienced landlords typically allow a 5-8% void allowance in their cashflow models -- equivalent to approximately 2.5 to 4 weeks per year -- when assessing the viability of a buy-to-let investment. The void allowance is a key variable in calculating net rental yield and should be based on local market data rather than national averages.
