There is no universal instruction for leaving water and electricity on or off. A sensible decision considers the property’s equipment, security systems, insurance requirements and the practical consequences of each choice.
Water
Turning off the supply may reduce the volume released by some leaks, but it can affect irrigation, appliances, heating equipment or other systems. Leaving it on supports normal operation but increases exposure if a connection fails. A plumber should advise where system design is unclear.
Electricity
Some homes need power for alarms, internet equipment, pumps, ventilation, refrigeration or remote sensors. Other circuits may be unnecessary during vacancy. Switching the entire supply off without understanding connected systems can create new problems.
Write down the chosen state
The property profile should identify what remains on, what may be tested and what an inspector must never alter without permission. Labels at the consumer board should be accurate, whilst any electrical concern is referred to a qualified electrician.
Align inspections with the decision
A home left with active water and multiple powered systems may justify more frequent oversight. A visual inspection confirms agreed status and looks for obvious warning signs; it is not electrical or plumbing certification.
Discuss the property during a Guardemar assessment and ensure your own insurer and technical advisers are consulted where relevant.
