Vacant building insurance covers a structure that nobody occupies, and the product is the same shape whether the building is a house or a warehouse: shorter terms, a narrower peril list, higher excesses and a set of conditions about security, water and inspection. What differs is which of those conditions the insurer leans on hardest.
What the cover contains
Fire, lightning, explosion and aircraft always. Storm, flood and impact usually. Escape of water, theft and malicious damage variably and often at a large excess. Property owners liability included, because an empty building still owes duties to anybody lawfully on or near it. Contents limited or excluded.
Commercial conditions
Security dominates. Locks to a specification, vulnerable openings secured or boarded, an alarm on higher value buildings, services isolated, and frequently the water drained because metal theft damages pipe runs and the flood costs more than the theft. Inspection intervals are shorter, sometimes weekly.
Residential conditions
Water and heat dominate. A minimum temperature maintained through the colder months or a full drain down, gutters clear, post removed, and inspections fortnightly in most wordings. Contents left in the building are usually limited and valuables excluded, which matters in probate cases where the belongings are still there.
Questions people ask about vacant building insurance
Is vacant the same as unoccupied?
For most UK insurers yes, though a few reserve vacant for a building also empty of contents and out of use.
Why do commercial voids have stricter security conditions?
Because metal theft makes an empty commercial unit a target, and the water damage after a stripped pipe run costs more than the theft itself.
How long are the terms?
Three, six or twelve months, usually renewable and often extendable monthly.
