There are a number of risks your property is vulnerable to when left unoccupied that need specific attention, including:
Burglary: thieves are far more likely to target a home they think is unoccupied.
Vandalism: an obviously empty home can be an easy target for vandalism. Common issues include; broken windows, graffiti and arson.
Water damage: burst water pipes can be a significant hazard and they are often costly to repair and put right any damage caused. Properties left empty in winter are particularly at risk.
Fire: as well as the risk of arson, fires can be caused by faulty wiring, gas leaks or a poorly maintained heating system. The risk of significant damage is much greater in unoccupied properties as hazards often go unnoticed until it is too late.
Squatters: the longer a home is unoccupied, the more appealing it is to squatters. Eviction of squatters can often incur a lengthy, and costly, legal battle.
